-**   xvmain.c --- Xv server extension main device independent module.
-**   
-** Author: 
-**
-**   David Carver (Digital Workstation Engineering/Project Athena)
-**
-** Revisions:
-**
-**   04.09.91 Carver
-**     - change: stop video always generates an event even when video
-**       wasn't active
-**
-**   29.08.91 Carver
-**     - change: unrealizing windows no longer preempts video
-**
-**   11.06.91 Carver
-**     - changed SetPortControl to SetPortAttribute
-**     - changed GetPortControl to GetPortAttribute
-**     - changed QueryBestSize
-**
-**   28.05.91 Carver
-**     - fixed Put and Get requests to not preempt operations to same drawable
-**
-**   15.05.91 Carver
-**     - version 2.0 upgrade
-**
-**   19.03.91 Carver
-**     - fixed Put and Get requests to honor grabbed ports.
-**     - fixed Video requests to update di structure with new drawable, and
-**       client after calling ddx.
-**
-**   24.01.91 Carver
-**     - version 1.4 upgrade
-**       
-** Notes:
-**
-**   Port structures reference client structures in a two different
-**   ways: when grabs, or video is active.  Each reference is encoded
-**   as fake client resources and thus when the client is goes away so
-**   does the reference (it is zeroed).  No other action is taken, so
-**   video doesn't necessarily stop.  It probably will as a result of
-**   other resources going away, but if a client starts video using
-**   none of its own resources, then the video will continue to play
-**   after the client disappears.

+**   xvmain.c --- Xv server extension main device independent module.

+**   

+** Author: 

+**

+**   David Carver (Digital Workstation Engineering/Project Athena)

+**

+** Revisions:

+**

+**   04.09.91 Carver

+**     - change: stop video always generates an event even when video

+**       wasn't active

+**

+**   29.08.91 Carver

+**     - change: unrealizing windows no longer preempts video

+**

+**   11.06.91 Carver

+**     - changed SetPortControl to SetPortAttribute

+**     - changed GetPortControl to GetPortAttribute

+**     - changed QueryBestSize

+**

+**   28.05.91 Carver

+**     - fixed Put and Get requests to not preempt operations to same drawable

+**

+**   15.05.91 Carver

+**     - version 2.0 upgrade

+**

+**   19.03.91 Carver

+**     - fixed Put and Get requests to honor grabbed ports.

+**     - fixed Video requests to update di structure with new drawable, and

+**       client after calling ddx.

+**

+**   24.01.91 Carver

+**     - version 1.4 upgrade

+**       

+** Notes:

+**

+**   Port structures reference client structures in a two different

+**   ways: when grabs, or video is active.  Each reference is encoded

+**   as fake client resources and thus when the client is goes away so

+**   does the reference (it is zeroed).  No other action is taken, so

+**   video doesn't necessarily stop.  It probably will as a result of

+**   other resources going away, but if a client starts video using

+**   none of its own resources, then the video will continue to play

+**   after the client disappears.

- * DBE MI Procedure: miDbeWinPrivDelete
- *
- * Description:
- *
- *     This is the MI function for deleting the dbeWindowPrivResType resource.
- *     This function is invoked indirectly by calling FreeResource() to free
- *     the resources associated with a DBE buffer ID.  There are 5 ways that
- *     miDbeWinPrivDelete() can be called by FreeResource().  They are:
- *
- *     - A DBE window is destroyed, in which case the DbeDestroyWindow()
- *       wrapper is invoked.  The wrapper calls FreeResource() for all DBE
- *       buffer IDs.
- *
- *     - miDbeAllocBackBufferName() calls FreeResource() to clean up resources
- *       after a buffer allocation failure.
- *
- *     - The PositionWindow wrapper, miDbePositionWindow(), calls
- *       FreeResource() when it fails to create buffers of the new size.
- *       FreeResource() is called for all DBE buffer IDs.
- *
- *     - FreeClientResources() calls FreeResource() when a client dies or the
- *       the server resets.
- *
- *     When FreeResource() is called for a DBE buffer ID, the delete function
- *     for the only other type of DBE resource, dbeDrawableResType, is also
- *     invoked.  This delete function (DbeDrawableDelete) is a NOOP to make
- *     resource deletion easier.  It is not guaranteed which delete function is
- *     called first.  Hence, we will let miDbeWinPrivDelete() free all DBE
- *     resources.
- *     
- *     This function deletes/frees the following stuff associated with
- *     the window private:
- *
- *     - the ID node in the ID list representing the passed in ID.
- *
- *     In addition, pDbeWindowPriv->nBufferIDs is decremented.
- *
- *     If this function is called for the last/only buffer ID for a window,
- *     these are additionally deleted/freed:
- *
- *     - the front and back pixmaps
- *     - the window priv itself

+ * DBE MI Procedure: miDbeWinPrivDelete

+ *

+ * Description:

+ *

+ *     This is the MI function for deleting the dbeWindowPrivResType resource.

+ *     This function is invoked indirectly by calling FreeResource() to free

+ *     the resources associated with a DBE buffer ID.  There are 5 ways that

+ *     miDbeWinPrivDelete() can be called by FreeResource().  They are:

+ *

+ *     - A DBE window is destroyed, in which case the DbeDestroyWindow()

+ *       wrapper is invoked.  The wrapper calls FreeResource() for all DBE

+ *       buffer IDs.

+ *

+ *     - miDbeAllocBackBufferName() calls FreeResource() to clean up resources

+ *       after a buffer allocation failure.

+ *

+ *     - The PositionWindow wrapper, miDbePositionWindow(), calls

+ *       FreeResource() when it fails to create buffers of the new size.

+ *       FreeResource() is called for all DBE buffer IDs.

+ *

+ *     - FreeClientResources() calls FreeResource() when a client dies or the

+ *       the server resets.

+ *

+ *     When FreeResource() is called for a DBE buffer ID, the delete function

+ *     for the only other type of DBE resource, dbeDrawableResType, is also

+ *     invoked.  This delete function (DbeDrawableDelete) is a NOOP to make

+ *     resource deletion easier.  It is not guaranteed which delete function is

+ *     called first.  Hence, we will let miDbeWinPrivDelete() free all DBE

+ *     resources.

+ *     

+ *     This function deletes/frees the following stuff associated with

- * (Suggestion: First read the macro, then read this explanation.

- * Either generate the next value to OR in to a pixel or break out of this

- *
- * This macro is used when we're trying to generate all 2^n combinations of
- * bits in mask.  What we're doing here is counting in binary, except that
- * the bits we use to count may not be contiguous.  This macro will be
- * called 2^n times, returning a different value in bits each time. Then
- * it will cause us to break out of a surrounding loop. (It will always be
- * called from within a while loop.)
- * On call: mask is the value we want to find all the combinations for
- * base has 1 bit set where the least significant bit of mask is set
- *
- * For example,if mask is 01010, base should be 0010 and we count like this:
- * 00010 (see this isn't so hard), 
- *     then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so
- *      we add that to bits getting (0100 + 0100) =
- * 01000 for our next value.
- *      then we add 0010 to get 
- * 01010 and we're done (easy as 1, 2, 3)

+ * This macro is used when we're trying to generate all 2^n combinations of

+ * the bits we use to count may not be contiguous.  This macro will be

+ * called 2^n times, returning a different value in bits each time. Then

+ * it will cause us to break out of a surrounding loop. (It will always be

+ * called from within a while loop.)

+ * On call: mask is the value we want to find all the combinations for

+ * base has 1 bit set where the least significant bit of mask is set

+ *

+ * For example,if mask is 01010, base should be 0010 and we count like this:

+ * 00010 (see this isn't so hard), 

+ *     then we add base to bits and get 0100. (bits & ~mask) is (0100 & 0100) so

+ *      we add that to bits getting (0100 + 0100) =

+ * 01000 for our next value.

+ *      then we add 0010 to get

-/* dixChangeGC(client, pGC, mask, pC32, pUnion)
- * 
- * This function was created as part of the Security extension
- * implementation.  The client performing the gc change must be passed so
- * that access checks can be performed on any tiles, stipples, or fonts
- * that are specified.  ddxen can call this too; they should normally
- * pass NullClient for the client since any access checking should have
- * already been done at a higher level.
- * 
- * Since we had to create a new function anyway, we decided to change the
- * way the list of gc values is passed to eliminate the compiler warnings
- * caused by the DoChangeGC interface.  You can pass the values via pC32
- * or pUnion, but not both; one of them must be NULL.  If you don't need
- * to pass any pointers, you can use either one:
- * 
- *     example calling dixChangeGC using pC32 parameter
- *
- *     CARD32 v[2];
- *     v[0] = foreground;
- *     v[1] = background;
- *     dixChangeGC(client, pGC, GCForeground|GCBackground, v, NULL);
- * 
- *     example calling dixChangeGC using pUnion parameter;
- *     same effect as above
- *
- *     ChangeGCVal v[2];
- *     v[0].val = foreground;
- *     v[1].val = background;
- *     dixChangeGC(client, pGC, GCForeground|GCBackground, NULL, v);
- * 
- * However, if you need to pass a pointer to a pixmap or font, you MUST
- * use the pUnion parameter.
- * 
- *     example calling dixChangeGC passing pointers in the value list
- *     v[1].ptr is a pointer to a pixmap
- *
- *     ChangeGCVal v[2];
- *     v[0].val = FillTiled;
- *     v[1].ptr = pPixmap;
- *     dixChangeGC(client, pGC, GCFillStyle|GCTile, NULL, v);
- * 
- * Note: we could have gotten by with just the pUnion parameter, but on
- * 64 bit machines that would have forced us to copy the value list that
- * comes in the ChangeGC request.
- * 
- * Ideally, we'd change all the DoChangeGC calls to dixChangeGC, but this
- * is far too many changes to consider at this time, so we've only
- * changed the ones that caused compiler warnings.  New code should use
- * dixChangeGC.

- * Predictable pointer acceleration
- *
- * 2006-2009 by Simon Thum (simon [dot] thum [at] gmx de)
- *
- * Serves 3 complementary functions:
- * 1) provide a sophisticated ballistic velocity estimate to improve
- *    the relation between velocity (of the device) and acceleration
- * 2) make arbitrary acceleration profiles possible
- * 3) decelerate by two means (constant and adaptive) if enabled
- *
- * Important concepts are the
- *
- * - Scheme
- *      which selects the basic algorithm
- *      (see devices.c/InitPointerAccelerationScheme)
- * - Profile
- *      which returns an acceleration
- *      for a given velocity
- *
- *  The profile can be selected by the user at runtime.
- *  The classic profile is intended to cleanly perform old-style
- *  function selection (threshold =/!= 0)

+ * Predictable pointer acceleration

+ *

+ * 2006-2009 by Simon Thum (simon [dot] thum [at] gmx de)

+ *

+ * Serves 3 complementary functions:

+ * 1) provide a sophisticated ballistic velocity estimate to improve

+ *    the relation between velocity (of the device) and acceleration

+ * 2) make arbitrary acceleration profiles possible

+ * 3) decelerate by two means (constant and adaptive) if enabled

+ *

+ * Important concepts are the

+ *

+ * - Scheme

+ *      which selects the basic algorithm

+ *      (see devices.c/InitPointerAccelerationScheme)

+ * - Profile

+ *      which returns an acceleration

+ *      for a given velocity

+ *

+ *  The profile can be selected by the user at runtime.

+ *  The classic profile is intended to cleanly perform old-style

+ *  function selection (threshold =/!= 0)

-/** \file
- * This file contains code than supports cursor movement, including the
- * code that initializes and reinitializes the screen positions and
- * computes screen overlap.
- *
- * "This code is based very closely on the XFree86 equivalent
- * (xfree86/common/xf86Cursor.c)."  --David Dawes.
- *
- * "This code was then extensively re-written, as explained here."
- * --Rik Faith
- *
- * The code in xf86Cursor.c used edge lists to implement the
- * CursorOffScreen function.  The edge list computation was complex
- * (especially in the face of arbitrarily overlapping screens) compared
- * with the speed savings in the CursorOffScreen function.  The new
- * implementation has erred on the side of correctness, readability, and
- * maintainability over efficiency.  For the common (non-edge) case, the
- * dmxCursorOffScreen function does avoid a loop over all the screens.
- * When the cursor has left the screen, all the screens are searched,
- * and the first screen (in dmxScreens order) containing the cursor will
- * be returned.  If run-time profiling shows that this routing is a
- * performance bottle-neck, then an edge list may have to be
- * reimplemented.  An edge list algorithm is O(edges) whereas the new
- * algorithm is O(dmxNumScreens).  Since edges is usually 1-3 and
- * dmxNumScreens may be 30-60 for large backend walls, this trade off
- * may be compelling.
- *
- * The xf86InitOrigins routine uses bit masks during the computation and
- * is therefore limited to the length of a word (e.g., 32 or 64 bits)
- * screens.  Because Xdmx is expected to be used with a large number of
- * backend displays, this limitation was removed.  The new
- * implementation has erred on the side of readability over efficiency,
- * using the dmxSL* routines to manage a screen list instead of a
- * bitmap, and a function call to decrease the length of the main
- * routine.  Both algorithms are of the same order, and both are called
- * only at server generation time, so trading clarity and long-term
- * maintainability for efficiency does not seem justified in this case.

+/** \file

+ * This file contains code than supports cursor movement, including the

+ * code that initializes and reinitializes the screen positions and

+ * computes screen overlap.

+ *

+ * "This code is based very closely on the XFree86 equivalent

+ * (xfree86/common/xf86Cursor.c)."  --David Dawes.

+ *

+ * "This code was then extensively re-written, as explained here."

+ * --Rik Faith

+ *

+ * The code in xf86Cursor.c used edge lists to implement the

+ * CursorOffScreen function.  The edge list computation was complex

+ * (especially in the face of arbitrarily overlapping screens) compared

+ * with the speed savings in the CursorOffScreen function.  The new

+ * implementation has erred on the side of correctness, readability, and

+ * maintainability over efficiency.  For the common (non-edge) case, the

+ * dmxCursorOffScreen function does avoid a loop over all the screens.

+ * When the cursor has left the screen, all the screens are searched,

+ * and the first screen (in dmxScreens order) containing the cursor will

+ * be returned.  If run-time profiling shows that this routing is a

+ * performance bottle-neck, then an edge list may have to be

+ * reimplemented.  An edge list algorithm is O(edges) whereas the new

+ * algorithm is O(dmxNumScreens).  Since edges is usually 1-3 and

+ * dmxNumScreens may be 30-60 for large backend walls, this trade off

+ * may be compelling.

+ *

+ * The xf86InitOrigins routine uses bit masks during the computation and

+ * is therefore limited to the length of a word (e.g., 32 or 64 bits)

+ * screens.  Because Xdmx is expected to be used with a large number of

+ * backend displays, this limitation was removed.  The new

+ * implementation has erred on the side of readability over efficiency,

+ * using the dmxSL* routines to manage a screen list instead of a

+ * bitmap, and a function call to decrease the length of the main

+ * routine.  Both algorithms are of the same order, and both are called

+ * only at server generation time, so trading clarity and long-term

+ * maintainability for efficiency does not seem justified in this case.

-	     *
-	     * When creating the default GC, the server opens up the
-	     * default font once for each screen, which in turn calls
-	     * the RealizeFont function pointer once for each screen.
-	     * During this process both dix's font refcnt and DMX's font
-	     * refcnt are incremented once for each screen.
-	     *
-	     * Later, when shutting down the X server, dix shuts down
-	     * each screen in reverse order.  During this shutdown
-	     * procedure, each screen's default GC is freed and then
-	     * that screen is closed by calling the CloseScreen function
-	     * pointer.  screenInfo.numScreens is then decremented after
-	     * closing each screen.  This procedure means that the dix's
-	     * font refcnt for the font used by the default GC's is
-	     * decremented once for each screen # greater than 0.
-	     * However, since dix's refcnt for the default font is not
-	     * yet 0 for each screen greater than 0, no call to the
-	     * UnrealizeFont function pointer is made for those screens.
-	     * Then, when screen 0 is being closed, dix's font refcnt
-	     * for the default GC's font is finally 0 and the font is
-	     * unrealized.  However, since screenInfo.numScreens has
-	     * been decremented already down to 1, only one call to
-	     * UnrealizeFont is made (for screen 0).  Thus, even though
-	     * RealizeFont was called once for each screen,
-	     * UnrealizeFont is only called for screen 0.
-	     *
-	     * This is a bug in dix.
-	     *
-	     * To avoid the memory leak of pFontPriv for each server
-	     * generation, we can also free pFontPriv if the refcnt is
-	     * not yet 0 but the # of screens is 1 -- i.e., the case
-	     * described in the dix bug above.  This is only a temporary
-	     * workaround until the bug in dix is solved.
-	     *
-	     * The other problem is that the font structure allocated by
-	     * XLoadQueryFont() above is not freed for screens > 0.
-	     * This problem cannot be worked around here since the back-
-	     * end displays for screens > 0 have already been closed by
-	     * the time this code is called from dix.
-	     *
-	     * When the bug in dix described above is fixed, then we can
-	     * remove the "|| screenInfo.numScreens == 1" code below and
-	     * the memory leaks will be eliminated.

+	     * When creating the default GC, the server opens up the

+	     * default font once for each screen, which in turn calls

+	     * the RealizeFont function pointer once for each screen.

+	     * During this process both dix's font refcnt and DMX's font

+	     * refcnt are incremented once for each screen.

+	     *

+	     * Later, when shutting down the X server, dix shuts down

+	     * each screen in reverse order.  During this shutdown

+	     * procedure, each screen's default GC is freed and then

+	     * that screen is closed by calling the CloseScreen function

+	     * pointer.  screenInfo.numScreens is then decremented after

+	     * closing each screen.  This procedure means that the dix's

+	     * font refcnt for the font used by the default GC's is

+	     * decremented once for each screen # greater than 0.

+	     * However, since dix's refcnt for the default font is not

+	     * yet 0 for each screen greater than 0, no call to the

+	     * UnrealizeFont function pointer is made for those screens.

+	     * Then, when screen 0 is being closed, dix's font refcnt

+	     * for the default GC's font is finally 0 and the font is

+	     * unrealized.  However, since screenInfo.numScreens has

+	     * been decremented already down to 1, only one call to

+	     * UnrealizeFont is made (for screen 0).  Thus, even though

+	     * RealizeFont was called once for each screen,

+	     * UnrealizeFont is only called for screen 0.

+	     *

+	     * This is a bug in dix.

+	     *

+	     * To avoid the memory leak of pFontPriv for each server

+	     * generation, we can also free pFontPriv if the refcnt is

+	     * not yet 0 but the # of screens is 1 -- i.e., the case

+	     * described in the dix bug above.  This is only a temporary

+	     * workaround until the bug in dix is solved.

+	     *

+	     * The other problem is that the font structure allocated by

+	     * XLoadQueryFont() above is not freed for screens > 0.

+	     * This problem cannot be worked around here since the back-

+	     * end displays for screens > 0 have already been closed by

+	     * the time this code is called from dix.

+	     *

+	     * When the bug in dix described above is fixed, then we can

+	     * remove the "|| screenInfo.numScreens == 1" code below and

+	     * the memory leaks will be eliminated.

+ * It is possible for one of the DMX "backend displays" to actually be

+ * smaller than the dimensions of the backend X server.  Therefore, it

+ * is possible for more than one of the DMX "backend displays" to be

+ * physically located on the same backend X server.  This situation must

+ * be detected so that cursor motion can be handled in an expected

+ * fashion.

+ *

+ * We could analyze the names used for the DMX "backend displays" (e.g.,

+ * the names passed to the -display command-line parameter), but there

+ * are many possible names for a single X display, and failing to detect

+ * sameness leads to very unexpected results.  Therefore, whenever the

+ * DMX server opens a window on a backend X server, a property value is

+ * queried and set on that backend to detect when another window is

+ * already open on that server.

+ *

+ * Further, it is possible that two different DMX server instantiations

+ * both have windows on the same physical backend X server.  This case

+ * is also detected so that pointer input is not taken from that

+ * particular backend X server.

+ *

+ * The routines in this file handle the property management. */

-<sect>Introduction
-
-<sect1>The Distributed Multihead X Server
-
-<p>Current Open Source multihead solutions are limited to a single
-physical machine.  A single X server controls multiple display devices,
-which can be arranged as independent heads or unified into a single
-desktop (with Xinerama).  These solutions are limited to the number of
-physical devices that can co-exist in a single machine (e.g., due to the
-number of AGP/PCI slots available for graphics cards).  Thus, large
-tiled displays are not currently possible.  The work described in this
-paper will eliminate the requirement that the display devices reside in
-the same physical machine.  This will be accomplished by developing a
-front-end proxy X server that will control multiple back-end X servers
-that make up the large display.
-
-<p>The overall structure of the distributed multihead X (DMX) project is
-as follows: A single front-end X server will act as a proxy to a set of
-back-end X servers, which handle all of the visible rendering.  X
-clients will connect to the front-end server just as they normally would
-to a regular X server.  The front-end server will present an abstracted
-view to the client of a single large display.  This will ensure that all
-standard X clients will continue to operate without modification
-(limited, as always, by the visuals and extensions provided by the X
-server).  Clients that are DMX-aware will be able to use an extension to
-obtain information about the back-end servers (e.g., for placement of
-pop-up windows, window alignments by the window manager, etc.).
-
-<p>The architecture of the DMX server is divided into two main sections:
-input (e.g., mouse and keyboard events) and output (e.g., rendering and
-windowing requests).  Each of these are describe briefly below, and the
-rest of this design document will describe them in greater detail.
-
-<p>The DMX server can receive input from three general types of input
-devices: "local" devices that are physically attached to the machine on
-which DMX is running, "backend" devices that are physically attached to
-one or more of the back-end X servers (and that generate events via the
-X protocol stream from the backend), and "console" devices that can be
-abstracted from any non-back-end X server.  Backend and console devices
-are treated differently because the pointer device on the back-end X
-server also controls the location of the hardware X cursor.  Full
-support for XInput extension devices is provided.
-
-<p>Rendering requests will be accepted by the front-end server; however,
-rendering to visible windows will be broken down as needed and sent to
-the appropriate back-end server(s) via X11 library calls for actual
-rendering.  The basic framework will follow a Xnest-style approach.  GC
-state will be managed in the front-end server and sent to the
-appropriate back-end server(s) as required.  Pixmap rendering will (at
-least initially) be handled by the front-end X server.  Windowing
-requests (e.g., ordering, mapping, moving, etc.) will handled in the
-front-end server.  If the request requires a visible change, the
-windowing operation will be translated into requests for the appropriate
-back-end server(s).  Window state will be mirrored in the back-end
-server(s) as needed.
-
-<sect1>Layout of Paper
-
-<p>The next section describes the general development plan that was
-actually used for implementation.  The final section discusses
-outstanding issues at the conclusion of development.  The first appendix
-provides low-level technical detail that may be of interest to those
-intimately familiar with the X server architecture.  The final appendix
-describes the four phases of development that were performed during the
-first two years of development.
-
-<p>The final year of work was divided into 9 tasks that are not
-described in specific sections of this document.  The major tasks during
-that time were the enhancement of the reconfiguration ability added in
-Phase IV, addition of support for a dynamic number of back-end displays
-(instead of a hard-coded limit), and the support for back-end display
-and input removal and addition.  This work is mentioned in this paper,
-but is not covered in detail.
-
-<!-- ============================================================ -->
-<sect>Development plan
-
-<p>This section describes the development plan from approximately June
-2001 through July 2003.
-
-<sect1>Bootstrap code
-
-<p>To allow for rapid development of the DMX server by multiple
-developers during the first development stage, the problem will be
-broken down into three tasks: the overall DMX framework, back-end
-rendering services and input device handling services.  However, before
-the work begins on these tasks, a simple framework that each developer
-could use was implemented to bootstrap the development effort.  This
-framework renders to a single back-end server and provides dummy input
-devices (i.e., the keyboard and mouse).  The simple back-end rendering
-service was implemented using the shadow framebuffer support currently
-available in the XFree86 environment.
-
-<p>Using this bootstrapping framework, each developer has been able to
-work on each of the tasks listed above independently as follows: the
-framework will be extended to handle arbitrary back-end server
-configurations; the back-end rendering services will be transitioned to
-the more efficient Xnest-style implementation; and, an input device
-framework to handle various input devices via the input extension will
-be developed.
-
-<p>Status: The boot strap code is complete.  <!-- August 2001 -->
-
-
-<sect1>Input device handling
-
-<p>An X server (including the front-end X server) requires two core
-input devices -- a keyboard and a pointer (mouse).  These core devices
-are handled and required by the core X11 protocol.  Additional types of
-input devices may be attached and utilized via the XInput extension.
-These are usually referred to as ``XInput extension devices'',
-
-<p>There are some options as to how the front-end X server gets its core
-input devices:
-
-<enum>
-    <item>Local Input. The physical input devices (e.g., keyboard and
-    mouse) can be attached directly to the front-end X server.  In this
-    case, the keyboard and mouse on the machine running the front-end X
-    server will be used.  The front-end will have drivers to read the
-    raw input from those devices and convert it into the required X
-    input events (e.g., key press/release, pointer button press/release,
-    pointer motion).  The front-end keyboard driver will keep track of
-    keyboard properties such as key and modifier mappings, autorepeat
-    state, keyboard sound and led state.  Similarly the front-end
-    pointer driver will keep track if pointer properties such as the
-    button mapping and movement acceleration parameters.  With this
-    option, input is handled fully in the front-end X server, and the
-    back-end X servers are used in a display-only mode.  This option was
-    implemented and works for a limited number of Linux-specific
-    devices.  Adding additional local input devices for other
-    architectures is expected to be relatively simple.
-
-    <p>The following options are available for implementing local input
-    devices:
-
-    <enum>
-        <item>The XFree86 X server has modular input drivers that could
-        be adapted for this purpose.  The mouse driver supports a wide
-        range of mouse types and interfaces, as well as a range of
-        Operating System platforms.  The keyboard driver in XFree86 is
-        not currently as modular as the mouse driver, but could be made
-        so.  The XFree86 X server also has a range of other input
-        drivers for extended input devices such as tablets and touch
-        screens.  Unfortunately, the XFree86 drivers are generally
-        complex, often simultaneously providing support for multiple
-        devices across multiple architectures; and rely so heavily on
-        XFree86-specific helper-functions, that this option was not
-        pursued.
-
-
-        <item>The <tt/kdrive/ X server in XFree86 has built-in drivers that
-        support PS/2 mice and keyboard under Linux.  The mouse driver
-        can indirectly handle other mouse types if the Linux utility
-        <tt/gpm/ is used as to translate the native mouse protocol into
-        PS/2 mouse format.  These drivers could be adapted and built in
-        to the front-end X server if this range of hardware and OS
-        support is sufficient.  While much simpler than the XFree86
-        drivers, the <tt/kdrive/ drivers were not used for the DMX
-        implementation.
-
-        <item>Reimplementation of keyboard and mouse drivers from
-        scratch for the DMX framework.  Because keyboard and mouse
-        drivers are relatively trivial to implement, this pathway was
-        selected.  Other drivers in the X source tree were referenced,
-        and significant contributions from other drivers are noted in
-        the DMX source code.
-    </enum>
-
-    <item>Backend Input.  The front-end can make use of the core input
-    devices attached to one or more of the back-end X servers.  Core
-    input events from multiple back-ends are merged into a single input
-    event stream.  This can work sanely when only a single set of input
-    devices is used at any given time.  The keyboard and pointer state
-    will be handled in the front-end, with changes propagated to the
-    back-end servers as needed.  This option was implemented and works
-    well.  Because the core pointer on a back-end controls the hardware
-    mouse on that back-end, core pointers cannot be treated as XInput
-    extension devices.  However, all back-end XInput extensions devices
-    can be mapped to either DMX core or DMX XInput extension devices.
-
-    <item>Console Input.  The front-end server could create a console
-    window that is displayed on an X server independent of the back-end
-    X servers.  This console window could display things like the
-    physical screen layout, and the front-end could get its core input
-    events from events delivered to the console window.  This option was
-    implemented and works well.  To help the human navigate, window
-    outlines are also displayed in the console window.  Further, console
-    windows can be used as either core or XInput extension devices.
-
-    <item>Other options were initially explored, but they were all
-    partial subsets of the options listed above and, hence, are
-    irrelevant.
-
-</enum>
-
-<p>Although extended input devices are not specifically mentioned in the
-Distributed X requirements, the options above were all implemented so
-that XInput extension devices were supported.
-
-<p>The bootstrap code (Xdmx) had dummy input devices, and these are
-still supported in the final version.  These do the necessary
-initialization to satisfy the X server's requirements for core pointer
-and keyboard devices, but no input events are ever generated.
-
-<p>Status: The input code is complete.  Because of the complexity of the
-XFree86 input device drivers (and their heavy reliance on XFree86
-infrastructure), separate low-level device drivers were implemented for
-Xdmx.  The following kinds of drivers are supported (in general, the
-devices can be treated arbitrarily as "core" input devices or as XInput
-"extension" devices; and multiple instances of different kinds of
-devices can be simultaneously available):
-    <enum>
-        <item> A "dummy" device drive that never generates events.
-
-        <item> "Local" input is from the low-level hardware on which the
-        Xdmx binary is running.  This is the only area where using the
-        XFree86 driver infrastructure would have been helpful, and then
-        only partially, since good support for generic USB devices does
-        not yet exist in XFree86 (in any case, XFree86 and kdrive driver
-        code was used where possible).  Currently, the following local
-        devices are supported under Linux (porting to other operating
-        systems should be fairly straightforward):
-        <itemize>
-            <item>Linux keyboard
-            <item>Linux serial mouse (MS)
-            <item>Linux PS/2 mouse
-            <item>USB keyboard
-            <item>USB mouse
-            <item>USB generic device (e.g., joystick, gamepad, etc.)
-        </itemize>
-
-        <item> "Backend" input is taken from one or more of the back-end
-        displays.  In this case, events are taken from the back-end X
-        server and are converted to Xdmx events.  Care must be taken so
-        that the sprite moves properly on the display from which input
-        is being taken.
-
-        <item> "Console" input is taken from an X window that Xdmx
-        creates on the operator's display (i.e., on the machine running
-        the Xdmx binary).  When the operator's mouse is inside the
-        console window, then those events are converted to Xdmx events.
-        Several special features are available: the console can display
-        outlines of windows that are on the Xdmx display (to facilitate
-        navigation), the cursor can be confined to the console, and a
-        "fine" mode can be activated to allow very precise cursor
-        positioning.
-    </enum>
-
-
-<!-- May 2002; July 2003 -->
-
-<sect1>Output device handling
-
-<p>The output of the DMX system displays rendering and windowing
-requests across multiple screens.  The screens are typically arranged in
-a grid such that together they represent a single large display.
-
-<p>The output section of the DMX code consists of two parts.  The first
-is in the front-end proxy X server (Xdmx), which accepts client
-connections, manages the windows, and potentially renders primitives but
-does not actually display any of the drawing primitives.  The second
-part is the back-end X server(s), which accept commands from the
-front-end server and display the results on their screens.
-
-<sect2>Initialization
-
-<p>The DMX front-end must first initialize its screens by connecting to
-each of the back-end X servers and collecting information about each of
-these screens.  However, the information collected from the back-end X
-servers might be inconsistent.  Handling these cases can be difficult
-and/or inefficient.  For example, a two screen system has one back-end X
-server running at 16bpp while the second is running at 32bpp.
-Converting rendering requests (e.g., XPutImage() or XGetImage()
-requests) to the appropriate bit depth can be very time consuming.
-Analyzing these cases to determine how or even if it is possible to
-handle them is required.  The current Xinerama code handles many of
-these cases (e.g., in PanoramiXConsolidate()) and will be used as a
-starting point.  In general, the best solution is to use homogeneous X
-servers and display devices.  Using back-end servers with the same depth
-is a requirement of the final DMX implementation.
-
-<p>Once this screen consolidation is finished, the relative position of
-each back-end X server's screen in the unified screen is initialized.  A
-full-screen window is opened on each of the back-end X servers, and the
-cursor on each screen is turned off.  The final DMX implementation can
-also make use of a partial-screen window, or multiple windows per
-back-end screen.
-
-<sect2>Handling rendering requests
-
-<p>After initialization, X applications connect to the front-end server.
-There are two possible implementations of how rendering and windowing
-requests are handled in the DMX system:
-
-<enum>
-    <item>A shadow framebuffer is used in the front-end server as the
-    render target.  In this option, all protocol requests are completely
-    handled in the front-end server.  All state and resources are
-    maintained in the front-end including a shadow copy of the entire
-    framebuffer.  The framebuffers attached to the back-end servers are
-    updated by XPutImage() calls with data taken directly from the
-    shadow framebuffer.
-
-    <p>This solution suffers from two main problems.  First, it does not
-    take advantage of any accelerated hardware available in the system.
-    Second, the size of the XPutImage() calls can be quite large and
-    thus will be limited by the bandwidth available.
-
-    <p>The initial DMX implementation used a shadow framebuffer by
-    default.
-
-    <item>Rendering requests are sent to each back-end server for
-    handling (as is done in the Xnest server described above).  In this
-    option, certain protocol requests are handled in the front-end
-    server and certain requests are repackaged and then sent to the
-    back-end servers.  The framebuffer is distributed across the
-    multiple back-end servers.  Rendering to the framebuffer is handled
-    on each back-end and can take advantage of any acceleration
-    available on the back-end servers' graphics display device.  State
-    is maintained both in the front and back-end servers.
-
-    <p>This solution suffers from two main drawbacks.  First, protocol
-    requests are sent to all back-end servers -- even those that will
-    completely clip the rendering primitive -- which wastes bandwidth
-    and processing time.  Second, state is maintained both in the front-
-    and back-end servers.  These drawbacks are not as severe as in
-    option 1 (above) and can either be overcome through optimizations or
-    are acceptable.  Therefore, this option will be used in the final
-    implementation.
-
-    <p>The final DMX implementation defaults to this mechanism, but also
-    supports the shadow framebuffer mechanism.  Several optimizations
-    were implemented to eliminate the drawbacks of the default
-    mechanism.  These optimizations are described the section below and
-    in Phase II of the Development Results (see appendix).
-
-</enum>
-
-<p>Status: Both the shadow framebuffer and Xnest-style code is complete.
-<!-- May 2002 -->
-
-
-<sect1>Optimizing DMX
-
-<p>Initially, the Xnest-style solution's performance will be measured
-and analyzed to determine where the performance bottlenecks exist.
-There are four main areas that will be addressed.
-
-<p>First, to obtain reasonable interactivity with the first development
-phase, XSync() was called after each protocol request.  The XSync()
-function flushes any pending protocol requests.  It then waits for the
-back-end to process the request and send a reply that the request has
-completed.  This happens with each back-end server and performance
-greatly suffers.  As a result of the way XSync() is called in the first
-development phase, the batching that the X11 library performs is
-effectively defeated.  The XSync() call usage will be analyzed and
-optimized by batching calls and performing them at regular intervals,
-except where interactivity will suffer (e.g., on cursor movements).
-
-<p>Second, the initial Xnest-style solution described above sends the
-repackaged protocol requests to all back-end servers regardless of
-whether or not they would be completely clipped out.  The requests that
-are trivially rejected on the back-end server wastes the limited
-bandwidth available.  By tracking clipping changes in the DMX X server's
-windowing code (e.g., by opening, closing, moving or resizing windows),
-we can determine whether or not back-end windows are visible so that
-trivial tests in the front-end server's GC ops drawing functions can
-eliminate these unnecessary protocol requests.
-
-<p>Third, each protocol request will be analyzed to determine if it is
-possible to break the request into smaller pieces at display boundaries.
-The initial ones to be analyzed are put and get image requests since
-they will require the greatest bandwidth to transmit data between the
-front and back-end servers.  Other protocol requests will be analyzed
-and those that will benefit from breaking them into smaller requests
-will be implemented.
-
-<p>Fourth, an extension is being considered that will allow font glyphs to
-be transferred from the front-end DMX X server to each back-end server.
-This extension will permit the front-end to handle all font requests and
-eliminate the requirement that all back-end X servers share the exact
-same fonts as the front-end server.  We are investigating the
-feasibility of this extension during this development phase.
-
-<p>Other potential optimizations will be determined from the performance
-analysis.
-
-<p>Please note that in our initial design, we proposed optimizing BLT
-operations (e.g., XCopyArea() and window moves) by developing an
-extension that would allow individual back-end servers to directly copy
-pixel data to other back-end servers.  This potential optimization was
-in response to the simple image movement implementation that required
-potentially many calls to GetImage() and PutImage().  However, the
-current Xinerama implementation handles these BLT operations
-differently.  Instead of copying data to and from screens, they generate
-expose events -- just as happens in the case when a window is moved from
-off a screen to on screen.  This approach saves the limited bandwidth
-available between front and back-end servers and is being standardized
-with Xinerama.  It also eliminates the potential setup problems and
-security issues resulting from having each back-end server open
-connections to all other back-end servers.  Therefore, we suggest
-accepting Xinerama's expose event solution.
-
-<p>Also note that the approach proposed in the second and third
-optimizations might cause backing store algorithms in the back-end to be
-defeated, so a DMX X server configuration flag will be added to disable
-these optimizations.
-
-<p>Status: The optimizations proposed above are complete.  It was
-determined that the using the xfs font server was sufficient and
-creating a new mechanism to pass glyphs was redundant; therefore, the
-fourth optimization proposed above was not included in DMX.
-<!-- September 2002 -->
-
-
-<sect1>DMX X extension support
-
-<p>The DMX X server keeps track of all the windowing information on the
-back-end X servers, but does not currently export this information to
-any client applications.  An extension will be developed to pass the
-screen information and back-end window IDs to DMX-aware clients.  These
-clients can then use this information to directly connect to and render
-to the back-end windows.  Bypassing the DMX X server allows DMX-aware
-clients to break up complex rendering requests on their own and send
-them directly to the windows on the back-end server's screens.  An
-example of a client that can make effective use of this extension is
-Chromium.
-
-<p>Status: The extension, as implemented, is fully documented in
-"Client-to-Server DMX Extension to the X Protocol".  Future changes
-might be required based on feedback and other proposed enhancements to
-DMX.  Currently, the following facilities are supported:

-<sect1>Common X extension support
-
-<p>The XInput, XKeyboard and Shape extensions are commonly used
-extensions to the base X11 protocol.  XInput allows multiple and
-non-standard input devices to be accessed simultaneously.  These input
-devices can be connected to either the front-end or back-end servers.
-XKeyboard allows much better keyboard mappings control.  Shape adds
-support for arbitrarily shaped windows and is used by various window
-managers.  Nearly all potential back-end X servers make these extensions
-available, and support for each one will be added to the DMX system.
-
-<p>In addition to the extensions listed above, support for the X
-Rendering extension (Render) is being developed.  Render adds digital
-image composition to the rendering model used by the X Window System.
-While this extension is still under development by Keith Packard of HP,
-support for the current version will be added to the DMX system.
-
-<p>Support for the XTest extension was added during the first
-development phase.
-
-<!-- WARNING: this list is duplicated in the Phase IV discussion -->
-<p>Status: The following extensions are supported and are discussed in
-more detail in Phase IV of the Development Results (see appendix):
-    BIG-REQUESTS,
-    DEC-XTRAP,

-<sect1>OpenGL support
-
-<p>OpenGL support using the Mesa code base exists in XFree86 release 4
-and later.  Currently, the direct rendering infrastructure (DRI)
-provides accelerated OpenGL support for local clients and unaccelerated
-OpenGL support (i.e., software rendering) is provided for non-local
-clients.
-
-<p>The single head OpenGL support in XFree86 4.x will be extended to use
-the DMX system.  When the front and back-end servers are on the same
-physical hardware, it is possible to use the DRI to directly render to
-the back-end servers.  First, the existing DRI will be extended to
-support multiple display heads, and then to support the DMX system.
-OpenGL rendering requests will be direct rendering to each back-end X
-server.  The DRI will request the screen layout (either from the
-existing Xinerama extension or a DMX-specific extension).  Support for
-synchronized swap buffers will also be added (on hardware that supports
-it).  Note that a single front-end server with a single back-end server
-on the same physical machine can emulate accelerated indirect rendering.
-
-<p>When the front and back-end servers are on different physical
-hardware or are using non-XFree86 4.x X servers, a mechanism to render
-primitives across the back-end servers will be provided.  There are
-several options as to how this can be implemented.
-
-<enum>
-    <item>The existing OpenGL support in each back-end server can be
-    used by repackaging rendering primitives and sending them to each
-    back-end server.  This option is similar to the unoptimized
-    Xnest-style approach mentioned above.  Optimization of this solution
-    is beyond the scope of this project and is better suited to other
-    distributed rendering systems.
-
-    <item>Rendering to a pixmap in the front-end server using the
-    current XFree86 4.x code, and then displaying to the back-ends via
-    calls to XPutImage() is another option.  This option is similar to
-    the shadow frame buffer approach mentioned above.  It is slower and
-    bandwidth intensive, but has the advantage that the back-end servers
-    are not required to have OpenGL support.
-</enum>
-
-<p>These, and other, options will be investigated in this phase of the
-work.
-
-<p>Work by others have made Chromium DMX-aware.  Chromium will use the
-DMX X protocol extension to obtain information about the back-end
-servers and will render directly to those servers, bypassing DMX.
-
-<p>Status: OpenGL support by the glxProxy extension was implemented by
-SGI and has been integrated into the DMX code base.
-<!-- May 2003-->

-<!-- ============================================================ -->
-<sect>Current issues
-
-<p>In this sections the current issues are outlined that require further
-investigation.
-
-<sect1>Fonts
-
-<p>The font path and glyphs need to be the same for the front-end and
-each of the back-end servers.  Font glyphs could be sent to the back-end
-servers as necessary but this would consume a significant amount of
-available bandwidth during font rendering for clients that use many
-different fonts (e.g., Netscape).  Initially, the font server (xfs) will
-be used to provide the fonts to both the front-end and back-end servers.
-Other possibilities will be investigated during development.
-
-<sect1>Zero width rendering primitives
-
-<p>To allow pixmap and on-screen rendering to be pixel perfect, all
-back-end servers must render zero width primitives exactly the same as
-the front-end renders the primitives to pixmaps.  For those back-end
-servers that do not exactly match, zero width primitives will be
-automatically converted to one width primitives.  This can be handled in
-the front-end server via the GC state.
-
-<sect1>Output scaling
-
-<p>With very large tiled displays, it might be difficult to read the
-information on the standard X desktop.  In particular, the cursor can be
-easily lost and fonts could be difficult to read.  Automatic primitive
-scaling might prove to be very useful.  We will investigate the
-possibility of scaling the cursor and providing a set of alternate
-pre-scaled fonts to replace the standard fonts that many applications
-use (e.g., fixed).  Other options for automatic scaling will also be
-investigated.
-
-<sect1>Per-screen colormaps
-
-<p>Each screen's default colormap in the set of back-end X servers
-should be able to be adjusted via a configuration utility.  This support
-is would allow the back-end screens to be calibrated via custom gamma
-tables.  On 24-bit systems that support a DirectColor visual, this type
-of correction can be accommodated.  One possible implementation would be
-to advertise to X client of the DMX server a TrueColor visual while
-using DirectColor visuals on the back-end servers to implement this type
-of color correction.  Other options will be investigated.
-
-<!-- ============================================================ -->
-<appendix>
-
-<sect>Background
-
-<p>This section describes the existing Open Source architectures that
-can be used to handle multiple screens and upon which this development
-project is based.  This section was written before the implementation
-was finished, and may not reflect actual details of the implementation.
-It is left for historical interest only.
-
-<sect1>Core input device handling
-
-<p>The following is a description of how core input devices are handled
-by an X server.
-
-<sect2>InitInput()
-
-<p>InitInput() is a DDX function that is called at the start of each
-server generation from the X server's main() function.  Its purpose is
-to determine what input devices are connected to the X server, register
-them with the DIX and MI layers, and initialize the input event queue.
-InitInput() does not have a return value, but the X server will abort if
-either a core keyboard device or a core pointer device are not
-registered.  Extended input (XInput) devices can also be registered in
-InitInput().
-
-<p>InitInput() usually has implementation specific code to determine
-which input devices are available.  For each input device it will be
-using, it calls AddInputDevice():
-
-<descrip>
-<tag/AddInputDevice()/ This DIX function allocates the device structure,
-registers a callback function (which handles device init, close, on and
-off), and returns the input handle, which can be treated as opaque.  It
-is called once for each input device.
-</descrip>
-
-<p>Once input handles for core keyboard and core pointer devices have
-been obtained from AddInputDevice(), they are registered as core devices
-by calling RegisterPointerDevice() and RegisterKeyboardDevice().  Each
-of these should be called once.  If both core devices are not
-registered, then the X server will exit with a fatal error when it
-attempts to start the input devices in InitAndStartDevices(), which is
-called directly after InitInput() (see below).
-
-<descrip>
-<tag/Register{Pointer,Keyboard}Device()/ These DIX functions take a
-handle returned from AddInputDevice() and initialize the core input
-device fields in inputInfo, and initialize the input processing and grab
-functions for each core input device.
-</descrip>
-
-<p>The core pointer device is then registered with the miPointer code
-(which does the high level cursor handling).  While this registration
-is not necessary for correct miPointer operation in the current XFree86
-code, it is still done mostly for compatibility reasons.
-
-<descrip>
-<tag/miRegisterPointerDevice()/ This MI function registers the core
-pointer's input handle with with the miPointer code.
-</descrip>
-
-<p>The final part of InitInput() is the initialization of the input
-event queue handling.  In most cases, the event queue handling provided
-in the MI layer is used.  The primary XFree86 X server uses its own
-event queue handling to support some special cases related to the XInput
-extension and the XFree86-specific DGA extension.  For our purposes, the
-MI event queue handling should be suitable.  It is initialized by
-calling mieqInit():
-
-<descrip>
-<tag/mieqInit()/ This MI function initializes the MI event queue for the
-core devices, and is passed the public component of the input handles
-for the two core devices.
-</descrip>
-
-<p>If a wakeup handler is required to deliver synchronous input
-events, it can be registered here by calling the DIX function
-RegisterBlockAndWakeupHandlers().  (See the devReadInput() description
-below.)
-
-<sect2>InitAndStartDevices()
-
-<p>InitAndStartDevices() is a DIX function that is called immediately
-after InitInput() from the X server's main() function.  Its purpose is
-to initialize each input device that was registered with
-AddInputDevice(), enable each input device that was successfully
-initialized, and create the list of enabled input devices.  Once each
-registered device is processed in this way, the list of enabled input
-devices is checked to make sure that both a core keyboard device and
-core pointer device were registered and successfully enabled.  If not,
-InitAndStartDevices() returns failure, and results in the the X server
-exiting with a fatal error.
-
-<p>Each registered device is initialized by calling its callback
-(dev-&gt;deviceProc) with the DEVICE_INIT argument:
-
-<descrip>
-<tag/(*dev-&gt;deviceProc)(dev, DEVICE_INIT)/ This function initializes the
-device structs with core information relevant to the device.
-
-<p>For pointer devices, this means specifying the number of buttons,
-default button mapping, the function used to get motion events (usually
-miPointerGetMotionEvents()), the function used to change/control the
-core pointer motion parameters (acceleration and threshold), and the
-motion buffer size.
-
-<p>For keyboard devices, this means specifying the keycode range,
-default keycode to keysym mapping, default modifier mapping, and the
-functions used to sound the keyboard bell and modify/control the
-keyboard parameters (LEDs, bell pitch and duration, key click, which
-keys are auto-repeating, etc).
-</descrip>
-
-<p>Each initialized device is enabled by calling EnableDevice():
-
-<descrip>
-<tag/EnableDevice()/ EnableDevice() calls the device callback with
-DEVICE_ON:
-    <descrip>
-    <tag/(*dev-&gt;deviceProc)(dev, DEVICE_ON)/ This typically opens and
-    initializes the relevant physical device, and when appropriate,
-    registers the device's file descriptor (or equivalent) as a valid
-    input source.
-    </descrip>
-
-    <p>EnableDevice() then adds the device handle to the X server's
-    global list of enabled devices.
-</descrip>
-
-<p>InitAndStartDevices() then verifies that a valid core keyboard and
-pointer has been initialized and enabled.  It returns failure if either
-are missing.
-
-<sect2>devReadInput()
-
-<p>Each device will have some function that gets called to read its
-physical input.  These may be called in a number of different ways.  In
-the case of synchronous I/O, they will be called from a DDX
-wakeup-handler that gets called after the server detects that new input is
-available.  In the case of asynchronous I/O, they will be called from a
-(SIGIO) signal handler triggered when new input is available.  This
-function should do at least two things: make sure that input events get
-enqueued, and make sure that the cursor gets moved for motion events
-(except if these are handled later by the driver's own event queue
-processing function, which cannot be done when using the MI event queue
-handling).
-
-<p>Events are queued by calling mieqEnqueue():
-
-<descrip>
-<tag/mieqEnqueue()/ This MI function is used to add input events to the
-event queue.  It is simply passed the event to be queued.
-</descrip>
-
-<p>The cursor position should be updated when motion events are
-enqueued, by calling either miPointerAbsoluteCursor() or
-miPointerDeltaCursor():
-
-<descrip>
-<tag/miPointerAbsoluteCursor()/ This MI function is used to move the
-cursor to the absolute coordinates provided.
-<tag/miPointerDeltaCursor()/ This MI function is used to move the cursor
-relative to its current position.
-</descrip>
-
-<sect2>ProcessInputEvents()
-
-<p>ProcessInputEvents() is a DDX function that is called from the X
-server's main dispatch loop when new events are available in the input
-event queue.  It typically processes the enqueued events, and updates
-the cursor/pointer position.  It may also do other DDX-specific event
-processing.
-
-<p>Enqueued events are processed by mieqProcessInputEvents() and passed
-to the DIX layer for transmission to clients:
-
-<descrip>
-<tag/mieqProcessInputEvents()/ This function processes each event in the
-event queue, and passes it to the device's input processing function.
-The DIX layer provides default functions to do this processing, and they
-handle the task of getting the events passed back to the relevant
-clients.
-<tag/miPointerUpdate()/ This function resynchronized the cursor position
-with the new pointer position.  It also takes care of moving the cursor
-between screens when needed in multi-head configurations.
-</descrip>
-
-
-<sect2>DisableDevice()
-
-<p>DisableDevice is a DIX function that removes an input device from the
-list of enabled devices.  The result of this is that the device no
-longer generates input events.  The device's data structures are kept in
-place, and disabling a device like this can be reversed by calling
-EnableDevice().  DisableDevice() may be called from the DDX when it is
-desirable to do so (e.g., the XFree86 server does this when VT
-switching).  Except for special cases, this is not normally called for
-core input devices.
-
-<p>DisableDevice() calls the device's callback function with
-<tt/DEVICE_OFF/:
-
-<descrip>
-<tag/(*dev-&gt;deviceProc)(dev, DEVICE_OFF)/ This typically closes the
-relevant physical device, and when appropriate, unregisters the device's
-file descriptor (or equivalent) as a valid input source.
-</descrip>
-
-<p>DisableDevice() then removes the device handle from the X server's
-global list of enabled devices.
-
-
-<sect2>CloseDevice()
-
-<p>CloseDevice is a DIX function that removes an input device from the
-list of available devices.  It disables input from the device and frees
-all data structures associated with the device.  This function is
-usually called from CloseDownDevices(), which is called from main() at
-the end of each server generation to close all input devices.
-
-<p>CloseDevice() calls the device's callback function with
-<tt/DEVICE_CLOSE/:
-
-<descrip>
-<tag/(*dev-&gt;deviceProc)(dev, DEVICE_CLOSE)/ This typically closes the
-relevant physical device, and when appropriate, unregisters the device's
-file descriptor (or equivalent) as a valid input source.  If any device
-specific data structures were allocated when the device was initialized,
-they are freed here.
-</descrip>
-
-<p>CloseDevice() then frees the data structures that were allocated
-for the device when it was registered/initialized.
-
-
-<sect2>LegalModifier()
-<!-- dmx/dmxinput.c - currently returns TRUE -->           
-<p>LegalModifier() is a required DDX function that can be used to
-restrict which keys may be modifier keys.  This seems to be present for
-historical reasons, so this function should simply return TRUE
-unconditionally.
-
-
-<sect1>Output handling
-
-<p>The following sections describe the main functions required to
-initialize, use and close the output device(s) for each screen in the X
-server.
-
-<sect2>InitOutput()
-
-<p>This DDX function is called near the start of each server generation
-from the X server's main() function.  InitOutput()'s main purpose is to
-initialize each screen and fill in the global screenInfo structure for
-each screen.  It is passed three arguments: a pointer to the screenInfo
-struct, which it is to initialize, and argc and argv from main(), which
-can be used to determine additional configuration information.
-
-<p>The primary tasks for this function are outlined below:
-
-<enum>
-    <item><bf/Parse configuration info:/ The first task of InitOutput()
-    is to parses any configuration information from the configuration
-    file.  In addition to the XF86Config file, other configuration
-    information can be taken from the command line.  The command line
-    options can be gathered either in InitOutput() or earlier in the
-    ddxProcessArgument() function, which is called by
-    ProcessCommandLine().  The configuration information determines the
-    characteristics of the screen(s).  For example, in the XFree86 X
-    server, the XF86Config file specifies the monitor information, the
-    screen resolution, the graphics devices and slots in which they are
-    located, and, for Xinerama, the screens' layout.
-
-    <item><bf/Initialize screen info:/ The next task is to initialize
-    the screen-dependent internal data structures.  For example, part of
-    what the XFree86 X server does is to allocate its screen and pixmap
-    private indices, probe for graphics devices, compare the probed
-    devices to the ones listed in the XF86Config file, and add the ones that
-    match to the internal xf86Screens&lsqb;&rsqb; structure.
-
-    <item><bf/Set pixmap formats:/ The next task is to initialize the
-    screenInfo's image byte order, bitmap bit order and bitmap scanline
-    unit/pad.  The screenInfo's pixmap format's depth, bits per pixel
-    and scanline padding is also initialized at this stage.
-
-    <item><bf/Unify screen info:/ An optional task that might be done at
-    this stage is to compare all of the information from the various
-    screens and determines if they are compatible (i.e., if the set of
-    screens can be unified into a single desktop).  This task has
-    potential to be useful to the DMX front-end server, if Xinerama's
-    PanoramiXConsolidate() function is not sufficient.
-</enum>
-
-<p>Once these tasks are complete, the valid screens are known and each
-of these screens can be initialized by calling AddScreen().
-
-<sect2>AddScreen()
-
-<p>This DIX function is called from InitOutput(), in the DDX layer, to
-add each new screen to the screenInfo structure.  The DDX screen
-initialization function and command line arguments (i.e., argc and argv)
-are passed to it as arguments.
-
-<p>This function first allocates a new Screen structure and any privates
-that are required.  It then initializes some of the fields in the Screen
-struct and sets up the pixmap padding information.  Finally, it calls
-the DDX screen initialization function ScreenInit(), which is described
-below.  It returns the number of the screen that were just added, or -1
-if there is insufficient memory to add the screen or if the DDX screen
-initialization fails.
-
-<sect2>ScreenInit()
-
-<p>This DDX function initializes the rest of the Screen structure with
-either generic or screen-specific functions (as necessary).  It also
-fills in various screen attributes (e.g., width and height in
-millimeters, black and white pixel values).
-
-<p>The screen init function usually calls several functions to perform
-certain screen initialization functions.  They are described below:
-
-<descrip>
-<tag/{mi,*fb}ScreenInit()/ The DDX layer's ScreenInit() function usually
-calls another layer's ScreenInit() function (e.g., miScreenInit() or
-fbScreenInit()) to initialize the fallbacks that the DDX driver does not
-specifically handle.
-
-<p>After calling another layer's ScreenInit() function, any
-screen-specific functions either wrap or replace the other layer's
-function pointers.  If a function is to be wrapped, each of the old
-function pointers from the other layer are stored in a screen private
-area.  Common functions to wrap are CloseScreen() and SaveScreen().
-
-<tag/miInitializeBackingStore()/ This MI function initializes the
-screen's backing storage functions, which are used to save areas of
-windows that are currently covered by other windows.
-
-<tag/miDCInitialize()/ This MI function initializes the MI cursor
-display structures and function pointers.  If a hardware cursor is used,
-the DDX layer's ScreenInit() function will wrap additional screen and
-the MI cursor display function pointers.
-</descrip>
-
-<p>Another common task for ScreenInit() function is to initialize the
-output device state.  For example, in the XFree86 X server, the
-ScreenInit() function saves the original state of the video card and
-then initializes the video mode of the graphics device.
-
-<sect2>CloseScreen()
-
-<p>This function restores any wrapped screen functions (and in
-particular the wrapped CloseScreen() function) and restores the state of
-the output device to its original state.  It should also free any
-private data it created during the screen initialization.
-
-<sect2>GC operations
-
-<p>When the X server is requested to render drawing primitives, it does
-so by calling drawing functions through the graphics context's operation
-function pointer table (i.e., the GCOps functions).  These functions
-render the basic graphics operations such as drawing rectangles, lines,
-text or copying pixmaps.  Default routines are provided either by the MI
-layer, which draws indirectly through a simple span interface, or by the
-framebuffer layers (e.g., CFB, MFB, FB), which draw directly to a
-linearly mapped frame buffer.
-
-<p>To take advantage of special hardware on the graphics device,
-specific GCOps functions can be replaced by device specific code.
-However, many times the graphics devices can handle only a subset of the
-possible states of the GC, so during graphics context validation,
-appropriate routines are selected based on the state and capabilities of
-the hardware.  For example, some graphics hardware can accelerate single
-pixel width lines with certain dash patterns.  Thus, for dash patterns
-that are not supported by hardware or for width 2 or greater lines, the
-default routine is chosen during GC validation.
-
-<p>Note that some pointers to functions that draw to the screen are
-stored in the Screen structure.  They include GetImage(), GetSpans(),
-PaintWindowBackground(), PaintWindowBorder(), CopyWindow() and
-RestoreAreas().
-
-<sect2>Xnest
-
-<p>The Xnest X server is a special proxy X server that relays the X
-protocol requests that it receives to a ``real'' X server that then
-processes the requests and displays the results, if applicable.  To the X
-applications, Xnest appears as if it is a regular X server.  However,
-Xnest is both server to the X application and client of the real X
-server, which will actually handle the requests.
-
-<p>The Xnest server implements all of the standard input and output
-initialization steps outlined above.
-
-<descrip>
-<tag/InitOutput()/ Xnest takes its configuration information from
-command line arguments via ddxProcessArguments().  This information
-includes the real X server display to connect to, its default visual
-class, the screen depth, the Xnest window's geometry, etc.  Xnest then
-connects to the real X server and gathers visual, colormap, depth and
-pixmap information about that server's display, creates a window on that
-server, which will be used as the root window for Xnest.
-
-<p>Next, Xnest initializes its internal data structures and uses the
-data from the real X server's pixmaps to initialize its own pixmap
-formats.  Finally, it calls AddScreen(xnestOpenScreen, argc, argv) to
-initialize each of its screens.
-
-<tag/ScreenInit()/ Xnest's ScreenInit() function is called
-xnestOpenScreen().  This function initializes its screen's depth and
-visual information, and then calls miScreenInit() to set up the default
-screen functions.  It then calls miInitializeBackingStore() and
-miDCInitialize() to initialize backing store and the software cursor.
-Finally, it replaces many of the screen functions with its own
-functions that repackage and send the requests to the real X server to
-which Xnest is attached.
-
-<tag/CloseScreen()/ This function frees its internal data structure
-allocations.  Since it replaces instead of wrapping screen functions,
-there are no function pointers to unwrap.  This can potentially lead to
-problems during server regeneration.
-
-<tag/GC operations/ The GC operations in Xnest are very simple since
-they leave all of the drawing to the real X server to which Xnest is
-attached.  Each of the GCOps takes the request and sends it to the
-real X server using standard Xlib calls.  For example, the X
-application issues a XDrawLines() call.  This function turns into a
-protocol request to Xnest, which calls the xnestPolylines() function
-through Xnest's GCOps function pointer table.  The xnestPolylines()
-function is only a single line, which calls XDrawLines() using the same
-arguments that were passed into it.  Other GCOps functions are very
-similar.  Two exceptions to the simple GCOps functions described above
-are the image functions and the BLT operations.
-
-<p>The image functions, GetImage() and PutImage(), must use a temporary
-image to hold the image to be put of the image that was just grabbed
-from the screen while it is in transit to the real X server or the
-client.  When the image has been transmitted, the temporary image is
-destroyed.
-
-<p>The BLT operations, CopyArea() and CopyPlane(), handle not only the
-copy function, which is the same as the simple cases described above,
-but also the graphics exposures that result when the GC's graphics
-exposure bit is set to True.  Graphics exposures are handled in a helper
-function, xnestBitBlitHelper().  This function collects the exposure
-events from the real X server and, if any resulting in regions being
-exposed, then those regions are passed back to the MI layer so that it
-can generate exposure events for the X application.
-</descrip>
-
-<p>The Xnest server takes its input from the X server to which it is
-connected.  When the mouse is in the Xnest server's window, keyboard and
-mouse events are received by the Xnest server, repackaged and sent back
-to any client that requests those events.
-
-<sect2>Shadow framebuffer
-
-<p>The most common type of framebuffer is a linear array memory that
-maps to the video memory on the graphics device.  However, accessing
-that video memory over an I/O bus (e.g., ISA or PCI) can be slow.  The
-shadow framebuffer layer allows the developer to keep the entire
-framebuffer in main memory and copy it back to video memory at regular
-intervals.  It also has been extended to handle planar video memory and
-rotated framebuffers.
-
-<p>There are two main entry points to the shadow framebuffer code:
-
-<descrip>
-<tag/shadowAlloc(width, height, bpp)/ This function allocates the in
-memory copy of the framebuffer of size width*height*bpp.  It returns a
-pointer to that memory, which will be used by the framebuffer
-ScreenInit() code during the screen's initialization.
-
-<tag/shadowInit(pScreen, updateProc, windowProc)/ This function
-initializes the shadow framebuffer layer.  It wraps several screen
-drawing functions, and registers a block handler that will update the
-screen.  The updateProc is a function that will copy the damaged regions
-to the screen, and the windowProc is a function that is used when the
-entire linear video memory range cannot be accessed simultaneously so
-that only a window into that memory is available (e.g., when using the
-VGA aperture).
-</descrip>
-
-<p>The shadow framebuffer code keeps track of the damaged area of each
-screen by calculating the bounding box of all drawing operations that
-have occurred since the last screen update.  Then, when the block handler
-is next called, only the damaged portion of the screen is updated.
-
-<p>Note that since the shadow framebuffer is kept in main memory, all
-drawing operations are performed by the CPU and, thus, no accelerated
-hardware drawing operations are possible.
-
-
-<sect1>Xinerama
-
-<p>Xinerama is an X extension that allows multiple physical screens
-controlled by a single X server to appear as a single screen.  Although
-the extension allows clients to find the physical screen layout via
-extension requests, it is completely transparent to clients at the core
-X11 protocol level.  The original public implementation of Xinerama came
-from Digital/Compaq.  XFree86 rewrote it, filling in some missing pieces
-and improving both X11 core protocol compliance and performance.  The
-Xinerama extension will be passing through X.Org's standardization
-process in the near future, and the sample implementation will be based
-on this rewritten version.
-
-<p>The current implementation of Xinerama is based primarily in the DIX
-(device independent) and MI (machine independent) layers of the X
-server.  With few exceptions the DDX layers do not need any changes to
-support Xinerama.  X server extensions often do need modifications to
-provide full Xinerama functionality.
-
-<p>The following is a code-level description of how Xinerama functions.
-
-<p>Note: Because the Xinerama extension was originally called the
-PanoramiX extension, many of the Xinerama functions still have the
-PanoramiX prefix.
-
-<descrip>
-    <tag/PanoramiXExtensionInit()/ PanoramiXExtensionInit() is a
-    device-independent extension function that is called at the start of
-    each server generation from InitExtensions(), which is called from
-    the X server's main() function after all output devices have been
-    initialized, but before any input devices have been initialized.
-
-    <p>PanoramiXNumScreens is set to the number of physical screens.  If
-    only one physical screen is present, the extension is disabled, and
-    PanoramiXExtensionInit() returns without doing anything else.
-
-    <p>The Xinerama extension is registered by calling AddExtension().
-    
-    <p>A local per-screen array of data structures
-    (panoramiXdataPtr&lsqb;&rsqb;)
-    is allocated for each physical screen, and GC and Screen private
-    indexes are allocated, and both GC and Screen private areas are
-    allocated for each physical screen.  These hold Xinerama-specific
-    per-GC and per-Screen data.  Each screen's CreateGC and CloseScreen
-    functions are wrapped by XineramaCreateGC() and
-    XineramaCloseScreen() respectively.  Some new resource classes are
-    created for Xinerama drawables and GCs, and resource types for
-    Xinerama windows, pixmaps and colormaps.
-
-    <p>A region (XineramaScreenRegions&lsqb;i&rsqb;) is initialized for each
-    physical screen, and single region (PanoramiXScreenRegion) is
-    initialized to be the union of the screen regions.  The
-    panoramiXdataPtr&lsqb;&rsqb; array is also initialized with the size and
-    origin of each screen.  The relative positioning information for the
-    physical screens is taken from the array
-    dixScreenOrigins&lsqb;&rsqb;, which
-    the DDX layer must initialize in InitOutput().  The bounds of the
-    combined screen is also calculated (PanoramiXPixWidth and
-    PanoramiXPixHeight).
-
-    <p>The DIX layer has a list of function pointers
-    (ProcVector&lsqb;&rsqb;) that
-    holds the entry points for the functions that process core protocol
-    requests.  The requests that Xinerama must intercept and break up
-    into physical screen-specific requests are wrapped.  The original
-    set is copied to SavedProcVector&lsqb;&rsqb;.  The types of requests
-    intercepted are Window requests, GC requests, colormap requests,
-    drawing requests, and some geometry-related requests.  This wrapping
-    allows the bulk of the protocol request processing to be handled
-    transparently to the DIX layer.  Some operations cannot be dealt with
-    in this way and are handled with Xinerama-specific code within the
-    DIX layer.
-
-    <tag/PanoramiXConsolidate()/ PanoramiXConsolidate() is a
-    device-independent extension function that is called directly from
-    the X server's main() function after extensions and input/output
-    devices have been initialized, and before the root windows are
-    defined and initialized.
-
-    <p>This function finds the set of depths (PanoramiXDepths&lsqb;&rsqb;) and
-    visuals (PanoramiXVisuals&lsqb;&rsqb;)
-    common to all of the physical screens.
-    PanoramiXNumDepths is set to the number of common depths, and
-    PanoramiXNumVisuals is set to the number of common visuals.
-    Resources are created for the single root window and the default
-    colormap.  Each of these resources has per-physical screen entries.
-
-    <tag/PanoramiXCreateConnectionBlock()/ PanoramiXConsolidate() is a
-    device-independent extension function that is called directly from
-    the X server's main() function after the per-physical screen root
-    windows are created.  It is called instead of the standard DIX
-    CreateConnectionBlock() function.  If this function returns FALSE,
-    the X server exits with a fatal error.  This function will return
-    FALSE if no common depths were found in PanoramiXConsolidate().
-    With no common depths, Xinerama mode is not possible.
-
-    <p>The connection block holds the information that clients get when
-    they open a connection to the X server.  It includes information
-    such as the supported pixmap formats, number of screens and the
-    sizes, depths, visuals, default colormap information, etc, for each
-    of the screens (much of information that <tt/xdpyinfo/ shows).  The
-    connection block is initialized with the combined single screen
-    values that were calculated in the above two functions.
-
-    <p>The Xinerama extension allows the registration of connection
-    block callback functions.  The purpose of these is to allow other
-    extensions to do processing at this point.  These callbacks can be
-    registered by calling XineramaRegisterConnectionBlockCallback() from
-    the other extension's ExtensionInit() function.  Each registered
-    connection block callback is called at the end of
-    PanoramiXCreateConnectionBlock().
-</descrip>
-
-<sect2>Xinerama-specific changes to the DIX code
-
-<p>There are a few types of Xinerama-specific changes within the DIX
-code.  The main ones are described here.
-
-<p>Functions that deal with colormap or GC -related operations outside of
-the intercepted protocol requests have a test added to only do the
-processing for screen numbers > 0.  This is because they are handled for
-the single Xinerama screen and the processing is done once for screen 0.
-
-<p>The handling of motion events does some coordinate translation between
-the physical screen's origin and screen zero's origin.  Also, motion
-events must be reported relative to the composite screen origin rather
-than the physical screen origins.
-
-<p>There is some special handling for cursor, window and event processing
-that cannot (either not at all or not conveniently) be done via the
-intercepted protocol requests.  A particular case is the handling of
-pointers moving between physical screens.
-
-<sect2>Xinerama-specific changes to the MI code
-
-<p>The only Xinerama-specific change to the MI code is in miSendExposures()
-to handle the coordinate (and window ID) translation for expose events.
-
-<sect2>Intercepted DIX core requests
-
-<p>Xinerama breaks up drawing requests for dispatch to each physical
-screen.  It also breaks up windows into pieces for each physical screen.
-GCs are translated into per-screen GCs.  Colormaps are replicated on
-each physical screen.  The functions handling the intercepted requests
-take care of breaking the requests and repackaging them so that they can
-be passed to the standard request handling functions for each screen in
-turn.  In addition, and to aid the repackaging, the information from
-many of the intercepted requests is used to keep up to date the
-necessary state information for the single composite screen.  Requests
-(usually those with replies) that can be satisfied completely from this
-stored state information do not call the standard request handling
-functions.

-
-<sect>Development Results
-
-<p>In this section the results of each phase of development are
-discussed.  This development took place between approximately June 2001
-and July 2003.
-
-<sect1>Phase I
-
-<p>The initial development phase dealt with the basic implementation
-including the bootstrap code, which used the shadow framebuffer, and the
-unoptimized implementation, based on an Xnest-style implementation.
-
-<sect2>Scope
-
-<p>The goal of Phase I is to provide fundamental functionality that can
-act as a foundation for ongoing work:
-<enum>
-    <item>Develop the proxy X server
-    <itemize>
-	<item>The proxy X server will operate on the X11 protocol and
-	relay requests as necessary to correctly perform the request.
-	<item>Work will be based on the existing work for Xinerama and
-	Xnest.
-	<item>Input events and windowing operations are handled in the
-	proxy server and rendering requests are repackaged and sent to
-	each of the back-end servers for display.
-	<item>The multiple screen layout (including support for
-	overlapping screens) will be user configurable via a
-	configuration file or through the configuration tool.
-    </itemize>
-    <item>Develop graphical configuration tool
-    <itemize>
-	<item>There will be potentially a large number of X servers to
-	configure into a single display.  The tool will allow the user
-	to specify which servers are involved in the configuration and
-	how they should be laid out.
-    </itemize>
-    <item>Pass the X Test Suite
-    <itemize>
-	<item>The X Test Suite covers the basic X11 operations.  All
-	tests known to succeed must correctly operate in the distributed
-	X environment.
-    </itemize>
-</enum>
-
-<p>For this phase, the back-end X servers are assumed to be unmodified X
-servers that do not support any DMX-related protocol extensions; future
-optimization pathways are considered, but are not implemented; and the
-configuration tool is assumed to rely only on libraries in the X source
-tree (e.g., Xt).
-
-<sect2>Results
-
-<p>The proxy X server, Xdmx, was developed to distribute X11 protocol
-requests to the set of back-end X servers.  It opens a window on each
-back-end server, which represents the part of the front-end's root
-window that is visible on that screen.  It mirrors window, pixmap and
-other state in each back-end server.  Drawing requests are sent to
-either windows or pixmaps on each back-end server.  This code is based
-on Xnest and uses the existing Xinerama extension.
-
-<p>Input events can be taken from (1) devices attached to the back-end
-server, (2) core devices attached directly to the Xdmx server, or (3)
-from a ``console'' window on another X server.  Events for these devices
-are gathered, processed and delivered to clients attached to the Xdmx
-server.
-
-<p>An intuitive configuration format was developed to help the user
-easily configure the multiple back-end X servers.  It was defined (see
-grammar in Xdmx man page) and a parser was implemented that is used by
-the Xdmx server and by a standalone xdmxconfig utility.  The parsing
-support was implemented such that it can be easily factored out of the X
-source tree for use with other tools (e.g., vdl).  Support for
-converting legacy vdl-format configuration files to the DMX format is
-provided by the vdltodmx utility.
-
-<p>Originally, the configuration file was going to be a subsection of
-XFree86's XF86Config file, but that was not possible since Xdmx is a
-completely separate X server.  Thus, a separate config file format was
-developed.  In addition, a graphical configuration
-tool, xdmxconfig, was developed to allow the user to create and arrange
-the screens in the configuration file.  The <bf/-configfile/ and <bf/-config/
-command-line options can be used to start Xdmx using a configuration
-file.
-
-<p>An extension that enables remote input testing is required for the X
-Test Suite to function.  During this phase, this extension (XTEST) was
-implemented in the Xdmx server.  The results from running the X Test
-Suite are described in detail below.
-
-<sect2>X Test Suite
-
-          <sect3> Introduction
-            <p>
-              The X Test Suite contains tests that verify Xlib functions
-              operate correctly.  The test suite is designed to run on a
-              single X server; however, since X applications will not be
-              able to tell the difference between the DMX server and a
-              standard X server, the X Test Suite should also run on the
-              DMX server.
-            <p>
-              The Xdmx server was tested with the X Test Suite, and the
-              existing failures are noted in this section.  To put these
-              results in perspective, we first discuss expected X Test
-              failures and how errors in underlying systems can impact
-              Xdmx test results.
-
-          <sect3>Expected Failures for a Single Head
-            <p>
-              A correctly implemented X server with a single screen is
-              expected to fail certain X Test tests.  The following
-              well-known errors occur because of rounding error in the X
-              server code:
-              <verb>
-XDrawArc: Tests 42, 63, 66, 73
-XDrawArcs: Tests 45, 66, 69, 76
-              </verb>
-            <p>
-              The following failures occur because of the high-level X
-              server implementation:
-              <verb>
-XLoadQueryFont: Test 1
-XListFontsWithInfo: Tests 3, 4
-XQueryFont: Tests 1, 2
-              </verb>
-            <p>
-              The following test fails when running the X server as root
-              under Linux because of the way directory modes are
-              interpreted:
-              <verb>
-XWriteBitmapFile: Test 3
-              </verb>
-            <p>
-              Depending on the video card used for the back-end, other
-              failures may also occur because of bugs in the low-level
-              driver implementation.  Over time, failures of this kind
-              are usually fixed by XFree86, but will show up in Xdmx
-              testing until then.
-
-          <sect3>Expected Failures for Xinerama
-            <p>
-              Xinerama fails several X Test Suite tests because of
-              design decisions made for the current implementation of
-              Xinerama.  Over time, many of these errors will be
-              corrected by XFree86 and the group working on a new
-              Xinerama implementation.  Therefore, Xdmx will also share
-              X Suite Test failures with Xinerama.
-            <p>
-              We may be able to fix or work-around some of these
-              failures at the Xdmx level, but this will require
-              additional exploration that was not part of Phase I.
-            <p>
-              Xinerama is constantly improving, and the list of
-              Xinerama-related failures depends on XFree86 version and
-              the underlying graphics hardware.  We tested with a
-              variety of hardware, including nVidia, S3, ATI Radeon,
-              and Matrox G400 (in dual-head mode).  The list below
-              includes only those failures that appear to be from the
-              Xinerama layer, and does not include failures listed in
-              the previous section, or failures that appear to be from
-              the low-level graphics driver itself:
-            <p>
-              These failures were noted with multiple Xinerama
-              configurations:
-              <verb>
-XCopyPlane: Tests 13, 22, 31 (well-known Xinerama implementation issue)
-XSetFontPath: Test 4
-XGetDefault: Test 5
-XMatchVisualInfo: Test 1
-              </verb>
-            <p>
-              These failures were noted only when using one dual-head
-              video card with a 4.2.99.x XFree86 server:
-              <verb>
-XListPixmapFormats: Test 1
-XDrawRectangles: Test 45
-              </verb>
-            <p>
-              These failures were noted only when using two video cards
-              from different vendors with a 4.1.99.x XFree86 server:
-              <verb>
-XChangeWindowAttributes: Test 32
-XCreateWindow: Test 30
-XDrawLine: Test 22
-XFillArc: Test 22
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-              </verb>
-
-          <sect3>Additional Failures from Xdmx
-            <p>
-              When running Xdmx, no unexpected failures were noted.
-              Since the Xdmx server is based on Xinerama, we expect to
-              have most of the Xinerama failures present in the Xdmx
-              server.  Similarly, since the Xdmx server must rely on the
-              low-level device drivers on each back-end server, we also
-              expect that Xdmx will exhibit most of the back-end
-              failures.  Here is a summary:
-              <verb>
-XListPixmapFormats: Test 1 (configuration dependent)
-XChangeWindowAttributes: Test 32
-XCreateWindow: Test 30
-XCopyPlane: Test 13, 22, 31
-XSetFontPath: Test 4
-XGetDefault: Test 5 (configuration dependent)
-XMatchVisualInfo: Test 1
-XRebindKeysym: Test 1 (configuration dependent)
-              </verb>
-            <p>
-              Note that this list is shorter than the combined list for
-              Xinerama because Xdmx uses different code paths to perform
-              some Xinerama operations.  Further, some Xinerama failures
-              have been fixed in the XFree86 4.2.99.x CVS repository.
-            
-          <sect3>Summary and Future Work
-            <p>
-              Running the X Test Suite on Xdmx does not produce any
-              failures that cannot be accounted for by the underlying
-              Xinerama subsystem used by the front-end or by the
-              low-level device-driver code running on the back-end X
-              servers.  The Xdmx server therefore is as ``correct'' as
-              possible with respect to the standard set of X Test Suite
-              tests.
-            <p>
-              During the following phases, we will continue to verify
-              Xdmx correctness using the X Test Suite.  We may also use
-              other tests suites or write additional tests that run
-              under the X Test Suite that specifically verify the
-              expected behavior of DMX.
-
-<sect2>Fonts
-
-<p>In Phase I, fonts are handled directly by both the front-end and the
-back-end servers, which is required since we must treat each back-end
-server during this phase as a ``black box''.  What this requires is that
-<bf/the front- and back-end servers must share the exact same font
-path/.  There are two ways to help make sure that all servers share the
-same font path:
-
-<enum>
-    <item>First, each server can be configured to use the same font
-    server.  The font server, xfs, can be configured to serve fonts to
-    multiple X servers via TCP.
-
-    <item>Second, each server can be configured to use the same font
-    path and either those font paths can be copied to each back-end
-    machine or they can be mounted (e.g., via NFS) on each back-end
-    machine.
-</enum>
-
-<p>One additional concern is that a client program can set its own font
-path, and if it does so, then that font path must be available on each
-back-end machine.
-
-<p>The -fontpath command line option was added to allow users to
-initialize the font path of the front end server.  This font path is
-propagated to each back-end server when the default font is loaded.  If
-there are any problems, an error message is printed, which will describe
-the problem and list the current font path.  For more information about
-setting the font path, see the -fontpath option description in the man
-page.
-
-<sect2>Performance
-
-<p>Phase I of development was not intended to optimize performance.  Its
-focus was on completely and correctly handling the base X11 protocol in
-the Xdmx server.  However, several insights were gained during Phase I,
-which are listed here for reference during the next phase of
-development.
-
-<enum>
-    <item>Calls to XSync() can slow down rendering since it requires a
-    complete round trip to and from a back-end server.  This is
-    especially problematic when communicating over long haul networks.
-    <item>Sending drawing requests to only the screens that they overlap
-    should improve performance.
-</enum>
-
-<sect2>Pixmaps
-
-<p>Pixmaps were originally expected to be handled entirely in the
-front-end X server; however, it was found that this overly complicated
-the rendering code and would have required sending potentially large
-images to each back server that required them when copying from pixmap
-to screen.  Thus, pixmap state is mirrored in the back-end server just
-as it is with regular window state.  With this implementation, the same
-rendering code that draws to windows can be used to draw to pixmaps on
-the back-end server, and no large image transfers are required to copy
-from pixmap to window.
-
-<!-- ============================================================ -->
-<sect1>Phase II
-
-<p>The second phase of development concentrates on performance
-optimizations.  These optimizations are documented here, with
-<tt/x11perf/ data to show how the optimizations improve performance.
-
-<p>All benchmarks were performed by running Xdmx on a dual processor
-1.4GHz AMD Athlon machine with 1GB of RAM connecting over 100baseT to
-two single-processor 1GHz Pentium III machines with 256MB of RAM and ATI
-Rage 128 (RF) video cards.  The front end was running Linux
-2.4.20-pre1-ac1 and the back ends were running Linux 2.4.7-10 and
-version 4.2.99.1 of XFree86 pulled from the XFree86 CVS repository on
-August 7, 2002.  All systems were running Red Hat Linux 7.2.
-
-<sect2>Moving from XFree86 4.1.99.1 to 4.2.0.0

-<p>For phase II, the working source tree was moved to the branch tagged
-with dmx-1-0-branch and was updated from version 4.1.99.1 (20 August
-2001) of the XFree86 sources to version 4.2.0.0 (18 January 2002).
-After this update, the following tests were noted to be more than 10%
-faster:

-<p>These changes were not caused by any changes in the DMX system, and
-may point to changes in the XFree86 tree or to tests that have more
-"jitter" than most other <tt/x11perf/ tests.

-<sect2>Global changes
-
-<p>During the development of the Phase II DMX server, several global
-changes were made.  These changes were also compared with the Phase I
-server.  The following tests were noted to be more than 10% faster:
-            <verb>
-1.13   Fill 300x300 opaque stippled trapezoid (161x145 stipple)

-0.76   Circulate Unmapped window (75 kids) 
-0.83   Circulate Unmapped window (100 kids) 
-            </verb>
-
-<p>For the remainder of this analysis, the baseline of comparison will
-be the Phase II deliverable with all optimizations disabled (unless
-otherwise noted).  This will highlight how the optimizations in
-isolation impact performance.
-
-<sect2>XSync() Batching
-
-<p>During the Phase I implementation, XSync() was called after every
-protocol request made by the DMX server.  This provided the DMX server
-with an interactive feel, but defeated X11's protocol buffering system
-and introduced round-trip wire latency into every operation.  During
-Phase II, DMX was changed so that protocol requests are no longer
-followed by calls to XSync().  Instead, the need for an XSync() is
-noted, and XSync() calls are only made every 100mS or when the DMX
-server specifically needs to make a call to guarantee interactivity.
-With this new system, X11 buffers protocol as much as possible during a
-100mS interval, and many unnecessary XSync() calls are avoided.
-
-<p>Out of more than 300 <tt/x11perf/ tests, 8 tests became more than 100
-times faster, with 68 more than 50X faster, 114 more than 10X faster,
-and 181 more than 2X faster.  See table below for summary.
-
-<p>The following tests were noted to be more than 10% slower with
-XSync() batching on:
-            <verb>
-0.88   500x500 tiled rectangle (161x145 tile) 
-0.89   Copy 500x500 from window to window 
-            </verb>
-
-<sect2>Offscreen Optimization
-
-<p>Windows span one or more of the back-end servers' screens; however,
-during Phase I development, windows were created on every back-end
-server and every rendering request was sent to every window regardless
-of whether or not that window was visible.  With the offscreen
-optimization, the DMX server tracks when a window is completely off of a
-back-end server's screen and, in that case, it does not send rendering
-requests to those back-end windows.  This optimization saves bandwidth
-between the front and back-end servers, and it reduces the number of
-XSync() calls.  The performance tests were run on a DMX system with only
-two back-end servers.  Greater performance gains will be had as the
-number of back-end servers increases.
-
-<p>Out of more than 300 <tt/x11perf/ tests, 3 tests were at least twice as
-fast, and 146 tests were at least 10% faster.  Two tests were more than
-10% slower with the offscreen optimization:
-            <verb>
-0.88   Hide/expose window via popup (4 kids) 
-0.89   Resize unmapped window (75 kids) 
-            </verb>
-
-<sect2>Lazy Window Creation Optimization
-
-<p>As mentioned above, during Phase I, windows were created on every
-back-end server even if they were not visible on that back-end.  With
-the lazy window creation optimization, the DMX server does not create
-windows on a back-end server until they are either visible or they
-become the parents of a visible window.  This optimization builds on the
-offscreen optimization (described above) and requires it to be enabled.
-
-<p>The lazy window creation optimization works by creating the window
-data structures in the front-end server when a client creates a window,
-but delays creation of the window on the back-end server(s).  A private
-window structure in the DMX server saves the relevant window data and
-tracks changes to the window's attributes and stacking order for later
-use.  The only times a window is created on a back-end server are (1)
-when it is mapped and is at least partially overlapping the back-end
-server's screen (tracked by the offscreen optimization), or (2) when the
-window becomes the parent of a previously visible window.  The first
-case occurs when a window is mapped or when a visible window is copied,
-moved or resized and now overlaps the back-end server's screen.  The
-second case occurs when starting a window manager after having created
-windows to which the window manager needs to add decorations.
-
-<p>When either case occurs, a window on the back-end server is created
-using the data saved in the DMX server's window private data structure.
-The stacking order is then adjusted to correctly place the window on the
-back-end and lastly the window is mapped.  From this time forward, the
-window is handled exactly as if the window had been created at the time
-of the client's request.
-
-<p>Note that when a window is no longer visible on a back-end server's
-screen (e.g., it is moved offscreen), the window is not destroyed;
-rather, it is kept and reused later if the window once again becomes
-visible on the back-end server's screen.  Originally with this
-optimization, destroying windows was implemented but was later rejected
-because it increased bandwidth when windows were opaquely moved or
-resized, which is common in many window managers.
-
-<p>The performance tests were run on a DMX system with only two back-end
-servers.  Greater performance gains will be had as the number of
-back-end servers increases.
-
-<p>This optimization improved the following <tt/x11perf/ tests by more
-than 10%:
-            <verb>

-1.12   Fill 100x100 stippled trapezoid (161x145 stipple) 
-1.20   Circulate Unmapped window (50 kids) 
-1.19   Circulate Unmapped window (75 kids) 
-            </verb>
-            
-<sect2>Subdividing Rendering Primitives
-
-<p>X11 imaging requests transfer significant data between the client and
-the X server.  During Phase I, the DMX server would then transfer the
-image data to each back-end server.  Even with the offscreen
-optimization (above), these requests still required transferring
-significant data to each back-end server that contained a visible
-portion of the window.  For example, if the client uses XPutImage() to
-copy an image to a window that overlaps the entire DMX screen, then the
-entire image is copied by the DMX server to every back-end server.
-
-<p>To reduce the amount of data transferred between the DMX server and
-the back-end servers when XPutImage() is called, the image data is
-subdivided and only the data that will be visible on a back-end server's
-screen is sent to that back-end server.  Xinerama already implements a
-subdivision algorithm for XGetImage() and no further optimization was
-needed.
-
-<p>Other rendering primitives were analyzed, but the time required to
-subdivide these primitives was a significant proportion of the time
-required to send the entire rendering request to the back-end server, so
-this optimization was rejected for the other rendering primitives.
-
-<p>Again, the performance tests were run on a DMX system with only two
-back-end servers.  Greater performance gains will be had as the number
-of back-end servers increases.
-
-<p>This optimization improved the following <tt/x11perf/ tests by more
-than 10%:

-<sect2>Summary of x11perf Data
-
-<p>With all of the optimizations on, 53 <tt/x11perf/ tests are more than
-100X faster than the unoptimized Phase II deliverable, with 69 more than
-50X faster, 73 more than 10X faster, and 199 more than twice as fast.
-No tests were more than 10% slower than the unoptimized Phase II
-deliverable.  (Compared with the Phase I deliverable, only Circulate
-Unmapped window (100 kids) was more than 10% slower than the Phase II
-deliverable.  As noted above, this test seems to have wider variability
-than other <tt/x11perf/ tests.)
-
-<p>The following table summarizes relative <tt/x11perf/ test changes for
-all optimizations individually and collectively.  Note that some of the
-optimizations have a synergistic effect when used together.

-<sect2>Profiling with OProfile
-
-<p>OProfile (available from http://oprofile.sourceforge.net/) is a
-system-wide profiler for Linux systems that uses processor-level
-counters to collect sampling data.  OProfile can provide information
-that is similar to that provided by <tt/gprof/, but without the
-necessity of recompiling the program with special instrumentation (i.e.,
-OProfile can collect statistical profiling information about optimized
-programs).  A test harness was developed to collect OProfile data for
-each <tt/x11perf/ test individually.
-
-<p>Test runs were performed using the RETIRED_INSNS counter on the AMD
-Athlon and the CPU_CLK_HALTED counter on the Intel Pentium III (with a
-test configuration different from the one described above).  We have
-examined OProfile output and have compared it with <tt/gprof/ output.
-This investigation has not produced results that yield performance
-increases in <tt/x11perf/ numbers.
-
-<!--
-<sect3>Retired Instructions
-
-<p>The initial tests using OProfile were done using the RETIRED_INSNS
-counter with DMX running on the dual-processor AMD Athlon machine - the
-same test configuration that was described above and that was used for
-other tests.  The RETIRED_INSNS counter counts retired instructions and
-showed drawing, text, copying, and image tests to be dominated (&gt;
-30%) by calls to Hash(), SecurityLookupIDByClass(),
-SecurityLookupIDByType(), and StandardReadRequestFromClient().  Some of
-these tests also executed significant instructions in
-WaitForSomething().
-
-<p>In contrast, the window tests executed significant
-instructions in SecurityLookupIDByType(), Hash(),
-StandardReadRequestFromClient(), but also executed significant
-instructions in other routines, such as ConfigureWindow().  Some time
-was spent looking at Hash() function, but optimizations in this routine
-did not lead to a dramatic increase in <tt/x11perf/ performance.
--->
-
-<!-- 
-<sect3>Clock Cycles
-
-<p>Retired instructions can be misleading because Intel/AMD instructions
-execute in variable amounts of time.  The OProfile tests were repeated
-using the Intel CPU_CLK_HALTED counter with DMX running on the second
-back-end machine.  Note that this is a different test configuration that
-the one described above.  However, these tests show the amount of time
-(as measured in CPU cycles) that are spent in each routine.  Because
-<tt/x11perf/ was running on the first back-end machine and because
-window optimizations were on, the load on the second back-end machine
-was not significant.
-
-<p>Using CPU_CLK_HALTED, DMX showed simple drawing
-tests spending more than 10% of their time in
-StandardReadRequestFromClient(), with significant time (&gt; 20% total)
-spent in SecurityLookupIDByClass(), WaitForSomething(), and Dispatch().
-For these tests, &lt; 5% of the time was spent in Hash(), which explains
-why optimizing the Hash() routine did not impact <tt/x11perf/ results.
-
-<p>The trapezoid, text, scrolling, copying, and image tests were
-dominated by time in ProcFillPoly(), PanoramiXFillPoly(), dmxFillPolygon(),
-SecurityLookupIDByClass(), SecurityLookupIDByType(), and
-StandardReadRequestFromClient().  Hash() time was generally above 5% but
-less than 10% of total time.

-<sect2>X Test Suite
-
-<p>The X Test Suite was run on the fully optimized DMX server using the
-configuration described above.  The following failures were noted:
-            <verb>
-XListPixmapFormats: Test 1              [1]

-<!-- ============================================================ -->
-<sect1>Phase III
-
-<p>During the third phase of development, support was provided for the
-following extensions: SHAPE, RENDER, XKEYBOARD, XInput.
-
-<sect2>SHAPE
-
-<p>The SHAPE extension is supported.  Test applications (e.g., xeyes and
-oclock) and window managers that make use of the SHAPE extension will
-work as expected.
-
-<sect2>RENDER
-
-<p>The RENDER extension is supported.  The version included in the DMX
-CVS tree is version 0.2, and this version is fully supported by Xdmx.
-Applications using only version 0.2 functions will work correctly;
-however, some apps that make use of functions from later versions do not
-properly check the extension's major/minor version numbers.  These apps
-will fail with a Bad Implementation error when using post-version 0.2
-functions.  This is expected behavior.  When the DMX CVS tree is updated
-to include newer versions of RENDER, support for these newer functions
-will be added to the DMX X server.
-
-<sect2>XKEYBOARD
-
-<p>The XKEYBOARD extension is supported.  If present on the back-end X
-servers, the XKEYBOARD extension will be used to obtain information
-about the type of the keyboard for initialization.  Otherwise, the
-keyboard will be initialized using defaults.  Note that this departs
-from older behavior: when Xdmx is compiled without XKEYBOARD support,
-the map from the back-end X server will be preserved.  With XKEYBOARD
-support, the map is not preserved because better information and control
-of the keyboard is available.
-
-<sect2>XInput
-
-<p>The XInput extension is supported.  Any device can be used as a core
-device and be used as an XInput extension device, with the exception of
-core devices on the back-end servers.  This limitation is present
-because cursor handling on the back-end requires that the back-end
-cursor sometimes track the Xdmx core cursor -- behavior that is
-incompatible with using the back-end pointer as a non-core device.
-
-<p>Currently, back-end extension devices are not available as Xdmx
-extension devices, but this limitation should be removed in the future.
-
-<p>To demonstrate the XInput extension, and to provide more examples for
-low-level input device driver writers, USB device drivers have been
-written for mice (usb-mou), keyboards (usb-kbd), and
-non-mouse/non-keyboard USB devices (usb-oth).  Please see the man page
-for information on Linux kernel drivers that are required for using
-these Xdmx drivers.
-
-<sect2>DPMS
-
-<p>The DPMS extension is exported but does not do anything at this time.
-
-<sect2>Other Extensions
-
-<p>The LBX,
-       SECURITY,
-       XC-APPGROUP, and

-
-<sect1>Phase IV
-
-<sect2>Moving to XFree86 4.3.0
-
-<p>For Phase IV, the recent release of XFree86 4.3.0 (27 February 2003)
-was merged onto the dmx.sourceforge.net CVS trunk and all work is
-proceeding using this tree.
-
-<sect2>Extensions 
-
-<sect3>XC-MISC (supported)
-
-<p>XC-MISC is used internally by the X library to recycle XIDs from the
-X server.  This is important for long-running X server sessions.  Xdmx
-supports this extension.  The X Test Suite passed and failed the exact
-same tests before and after this extension was enabled.
-<!-- Tested February/March 2003 -->
-
-<sect3>Extended-Visual-Information (supported)
-
-<p>The Extended-Visual-Information extension provides a method for an X
-client to obtain detailed visual information.  Xdmx supports this
-extension.  It was tested using the <tt>hw/dmx/examples/evi</tt> example
-program.  <bf/Note that this extension is not Xinerama-aware/ -- it will
-return visual information for each screen even though Xinerama is
-causing the X server to export a single logical screen.
-<!-- Tested March 2003 -->
-
-<sect3>RES (supported)
-
-<p>The X-Resource extension provides a mechanism for a client to obtain
-detailed information about the resources used by other clients.  This
-extension was tested with the <tt>hw/dmx/examples/res</tt> program.  The
-X Test Suite passed and failed the exact same tests before and after
-this extension was enabled.
-<!-- Tested March 2003 -->
-
-<sect3>BIG-REQUESTS (supported)
-
-<p>This extension enables the X11 protocol to handle requests longer
-than 262140 bytes.  The X Test Suite passed and failed the exact same
-tests before and after this extension was enabled.
-<!-- Tested March 2003 -->
-
-<sect3>XSYNC (supported)
-
-<p>This extension provides facilities for two different X clients to
-synchronize their requests.  This extension was minimally tested with
-<tt/xdpyinfo/ and the X Test Suite passed and failed the exact same
-tests before and after this extension was enabled.
-<!-- Tested March 2003 -->
-
-<sect3>XTEST, RECORD, DEC-XTRAP (supported) and XTestExtension1 (not supported)
-
-<p>The XTEST and RECORD extension were developed by the X Consortium for
-use in the X Test Suite and are supported as a standard in the X11R6
-tree.  They are also supported in Xdmx.  When X Test Suite tests that
-make use of the XTEST extension are run, Xdmx passes and fails exactly
-the same tests as does a standard XFree86 X server.  When the
-<tt/rcrdtest/ test (a part of the X Test Suite that verifies the RECORD
-extension) is run, Xdmx passes and fails exactly the same tests as does
-a standard XFree86 X server. <!-- Tested February/March 2003 -->
-
-<p>There are two older XTEST-like extensions: DEC-XTRAP and
-XTestExtension1.  The XTestExtension1 extension was developed for use by
-the X Testing Consortium for use with a test suite that eventually
-became (part of?) the X Test Suite.  Unlike XTEST, which only allows
-events to be sent to the server, the XTestExtension1 extension also
-allowed events to be recorded (similar to the RECORD extension).  The
-second is the DEC-XTRAP extension that was developed by the Digital
-Equipment Corporation.
-
-<p>The DEC-XTRAP extension is available from Xdmx and has been tested
-with the <tt/xtrap*/ tools which are distributed as standard X11R6
-clients. <!-- Tested March 2003 -->
-
-<p>The XTestExtension1 is <em/not/ supported because it does not appear
-to be used by any modern X clients (the few that support it also support
-XTEST) and because there are no good methods available for testing that
-it functions correctly (unlike XTEST and DEC-XTRAP, the code for
-XTestExtension1 is not part of the standard X server source tree, so
-additional testing is important). <!-- Tested March 2003 -->
-
-<p>Most of these extensions are documented in the X11R6 source tree.

-locate -- for completeness and historical interest, citations are

-
-<sect3>MIT-MISC (not supported)
-
-<p>The MIT-MISC extension is used to control a bug-compatibility flag
-that provides compatibility with xterm programs from X11R1 and X11R2.
-There does not appear to be a single client available that makes use of
-this extension and there is not way to verify that it works correctly.
-The Xdmx server does <em/not/ support MIT-MISC.
-
-<sect3>SCREENSAVER (not supported)
-
-<p>This extension provides special support for the X screen saver.  It
-was tested with beforelight, which appears to be the only client that
-works with it.  When Xinerama was not active, <tt/beforelight/ behaved
-as expected.  However, when Xinerama was active, <tt/beforelight/ did
-not behave as expected.  Further, when this extension is not active,
-<tt/xscreensaver/ (a widely-used X screen saver program) did not behave
-as expected.  Since this extension is not Xinerama-aware and is not
-commonly used with expected results by clients, we have left this
-extension disabled at this time.
-
-<sect3>GLX (supported)
-
-<p>The GLX extension provides OpenGL and GLX windowing support.  In
-Xdmx, the extension is called glxProxy, and it is Xinerama aware.  It
-works by either feeding requests forward through Xdmx to each of the
-back-end servers or handling them locally.  All rendering requests are
-handled on the back-end X servers.  This code was donated to the DMX
-project by SGI.  For the X Test Suite results comparison, see below.
-
-<sect3>RENDER (supported)
-
-<p>The X Rendering Extension (RENDER) provides support for digital image
-composition.  Geometric and text rendering are supported.  RENDER is
-partially Xinerama-aware, with text and the most basic compositing
-operator; however, its higher level primitives (triangles, triangle
-strips, and triangle fans) are not yet Xinerama-aware.  The RENDER
-extension is still under development, and is currently at version 0.8.
-Additional support will be required in DMX as more primitives and/or
-requests are added to the extension.
-
-<p>There is currently no test suite for the X Rendering Extension;
-however, there has been discussion of developing a test suite as the
-extension matures.  When that test suite becomes available, additional
-testing can be performed with Xdmx.  The X Test Suite passed and failed
-the exact same tests before and after this extension was enabled.
-

-<sect2>Additional Testing with the X Test Suite
-
-<sect3>XFree86 without XTEST
-
-<p>After the release of XFree86 4.3.0, we retested the XFree86 X server
-with and without using the XTEST extension.  When the XTEST extension
-was <em/not/ used for testing, the XFree86 4.3.0 server running on our
-usual test system with a Radeon VE card reported unexpected failures in
-the following tests:
-<verb>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XGetDefault: Test 5
-XRebindKeysym: Test 1
-</verb>
-
-<sect3>XFree86 with XTEST
-
-<p>When using the XTEST extension, the XFree86 4.3.0 server reported the
-following errors:
-<verb>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XGetDefault: Test 5
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests 20, 21, 24
-XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25
-XGrabKey: Test 8
-XSetPointerMapping: Test 3
-XUngrabButton: Test 4
-</verb>
-
-<p>While these errors may be important, they will probably be fixed
-eventually in the XFree86 source tree.  We are particularly interested
-in demonstrating that the Xdmx server does not introduce additional
-failures that are not known Xinerama failures.
-
-<sect3>Xdmx with XTEST, without Xinerama, without GLX
-
-<p>Without Xinerama, but using the XTEST extension, the following errors
-were reported from Xdmx (note that these are the same as for the XFree86
-4.3.0, except that XGetDefault no longer fails):
-<verb>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests  20, 21, 24
-XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25
-XGrabKey: Test 8
-XSetPointerMapping: Test 3
-XUngrabButton: Test 4
-</verb>
-
-<sect3>Xdmx with XTEST, with Xinerama, without GLX
-
-<p>With Xinerama, using the XTEST extension, the following errors
-were reported from Xdmx:
-<verb>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests 20, 21, 24
-XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25
-XGrabKey: Test 8
-XSetPointerMapping: Test 3
-XUngrabButton: Test 4
-
-XCopyPlane: Tests 13, 22, 31 (well-known XTEST/Xinerama interaction issue)
-XDrawLine: Test 67
-XDrawLines: Test 91
-XDrawSegments: Test 68
-</verb>
-Note that the first two sets of errors are the same as for the XFree86
-4.3.0 server, and that the XCopyPlane error is a well-known error
-resulting from an XTEST/Xinerama interaction when the request crosses a
-screen boundary.  The XDraw* errors are resolved when the tests are run
-individually and they do not cross a screen boundary.  We will
-investigate these errors further to determine their cause.
-
-<sect3>Xdmx with XTEST, with Xinerama, with GLX
-
-<p>With GLX enabled, using the XTEST extension, the following errors
-were reported from Xdmx (these results are from early during the Phase
-IV development, but were confirmed with a late Phase IV snapshot):
-<verb>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests 20, 21, 24
-XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25

-Note that the first two sets of errors are the same as for the XFree86
-4.3.0 server, and that the third set has different failures than when
-Xdmx does not include GLX support.  Since the GLX extension adds new
-visuals to support GLX's visual configs and the X Test Suite runs tests
-over the entire set of visuals, additional rendering tests were run and
-presumably more of them crossed a screen boundary.  This conclusion is
-supported by the fact that nearly all of the rendering errors reported
-are resolved when the tests are run individually and they do no cross a
-screen boundary.
-
-<p>Further, when hardware rendering is disabled on the back-end displays,
-many of the errors in the third set are eliminated, leaving only:

-
-<sect3>Conclusion
-
-<p>We conclude that all of the X Test Suite errors reported for Xdmx are
-the result of errors in the back-end X server or the Xinerama
-implementation.  Further, all of these errors that can be reasonably
-fixed at the Xdmx layer have been.  (Where appropriate, we have
-submitted patches to the XFree86 and Xinerama upstream maintainers.)
-
-<sect2>Dynamic Reconfiguration
-
-<p>During this development phase, dynamic reconfiguration support was
-added to DMX.  This support allows an application to change the position
-and offset of a back-end server's screen.  For example, if the
-application would like to shift a screen slightly to the left, it could
-query Xdmx for the screen's &lt;x,y&gt; position and then dynamically
-reconfigure that screen to be at position &lt;x+10,y&gt;.  When a screen
-is dynamically reconfigured, input handling and a screen's root window
-dimensions are adjusted as needed.  These adjustments are transparent to
-the user.
-
-<sect3>Dynamic reconfiguration extension
-
-<p>The application interface to DMX's dynamic reconfiguration is through
-a function in the DMX extension library:
-<verb>
-Bool DMXReconfigureScreen(Display *dpy, int screen, int x, int y)
-</verb>
-where <it/dpy/ is DMX server's display, <it/screen/ is the number of the
-screen to be reconfigured, and <it/x/ and <it/y/ are the new upper,
-left-hand coordinates of the screen to be reconfigured.
-
-<p>The coordinates are not limited other than as required by the X
-protocol, which limits all coordinates to a signed 16 bit number.  In
-addition, all coordinates within a screen must also be legal values.
-Therefore, setting a screen's upper, left-hand coordinates such that the
-right or bottom edges of the screen is greater than 32,767 is illegal.
-
-<sect3>Bounding box
-
-<p>When the Xdmx server is started, a bounding box is calculated from
-the screens' layout given either on the command line or in the
-configuration file.  This bounding box is currently fixed for the
-lifetime of the Xdmx server.
-
-<p>While it is possible to move a screen outside of the bounding box, it
-is currently not possible to change the dimensions of the bounding box.
-For example, it is possible to specify coordinates of &lt;-100,-100&gt;
-for the upper, left-hand corner of the bounding box, which was
-previously at coordinates &lt;0,0&gt;.  As expected, the screen is moved
-down and to the right; however, since the bounding box is fixed, the
-left side and upper portions of the screen exposed by the
-reconfiguration are no longer accessible on that screen.  Those
-inaccessible regions are filled with black.
-
-<p>This fixed bounding box limitation will be addressed in a future
-development phase.
-
-<sect3>Sample applications
-
-<p>An example of where this extension is useful is in setting up a video
-wall.  It is not always possible to get everything perfectly aligned,
-and sometimes the positions are changed (e.g., someone might bump into a
-projector).  Instead of physically moving projectors or monitors, it is
-now possible to adjust the positions of the back-end server's screens
-using the dynamic reconfiguration support in DMX.
-
-<p>Other applications, such as automatic setup and calibration tools,
-can make use of dynamic reconfiguration to correct for projector
-alignment problems, as long as the projectors are still arranged
-rectilinearly.  Horizontal and vertical keystone correction could be
-applied to projectors to correct for non-rectilinear alignment problems;
-however, this must be done external to Xdmx.
-
-<p>A sample test program is included in the DMX server's examples
-directory to demonstrate the interface and how an application might use
-dynamic reconfiguration.  See <tt/dmxreconfig.c/ for details.
-
-<sect3>Additional notes
-
-<p>In the original development plan, Phase IV was primarily devoted to
-adding OpenGL support to DMX; however, SGI became interested in the DMX
-project and developed code to support OpenGL/GLX.  This code was later
-donated to the DMX project and integrated into the DMX code base, which
-freed the DMX developers to concentrate on dynamic reconfiguration (as
-described above).
-
-<sect2>Doxygen documentation
-
-<p>Doxygen is an open-source (GPL) documentation system for generating
-browseable documentation from stylized comments in the source code.  We
-have placed all of the Xdmx server and DMX protocol source code files
-under Doxygen so that comprehensive documentation for the Xdmx source
-code is available in an easily browseable format.
-
-<sect2>Valgrind
-
-<p>Valgrind, an open-source (GPL) memory debugger for Linux, was used to
-search for memory management errors.  Several memory leaks were detected
-and repaired.  The following errors were not addressed:
-<enum>
-    <item>
-        When the X11 transport layer sends a reply to the client, only
-        those fields that are required by the protocol are filled in --
-        unused fields are left as uninitialized memory and are therefore
-        noted by valgrind.  These instances are not errors and were not
-        repaired.
-    <item>
-        At each server generation, glxInitVisuals allocates memory that
-        is never freed.  The amount of memory lost each generation
-        approximately equal to 128 bytes for each back-end visual.
-        Because the code involved is automatically generated, this bug
-        has not been fixed and will be referred to SGI.
-    <item>
-        At each server generation, dmxRealizeFont calls XLoadQueryFont,
-        which allocates a font structure that is not freed.
-        dmxUnrealizeFont can free the font structure for the first
-        screen, but cannot free it for the other screens since they are
-        already closed by the time dmxUnrealizeFont could free them.
-        The amount of memory lost each generation is approximately equal
-        to 80 bytes per font per back-end.  When this bug is fixed in
-        the the X server's device-independent (dix) code, DMX will be
-        able to properly free the memory allocated by XLoadQueryFont.
-</enum>
-
-<sect2>RATS
-
-<p>RATS (Rough Auditing Tool for Security) is an open-source (GPL)
-security analysis tool that scans source code for common
-security-related programming errors (e.g., buffer overflows and TOCTOU
-races).  RATS was used to audit all of the code in the hw/dmx directory
-and all "High" notations were checked manually.  The code was either
-re-written to eliminate the warning, or a comment containing "RATS" was
-inserted on the line to indicate that a human had checked the code.
-Unrepaired warnings are as follows:
-<enum>
-    <item>
-        Fixed-size buffers are used in many areas, but code has been
-        added to protect against buffer overflows (e.g., XmuSnprint).
-        The only instances that have not yet been fixed are in
-        config/xdmxconfig.c (which is not part of the Xdmx server) and
-        input/usb-common.c.
-    <item>
-        vprintf and vfprintf are used in the logging routines.  In
-        general, all uses of these functions (e.g., dmxLog) provide a
-        constant format string from a trusted source, so the use is
-        relatively benign.
-    <item>
-        glxProxy/glxscreens.c uses getenv and strcat.  The use of these
-        functions is safe and will remain safe as long as
-        ExtensionsString is longer then GLXServerExtensions (ensuring
-        this may not be ovious to the casual programmer, but this is in
-        automatically generated code, so we hope that the generator
-        enforces this constraint).

+<sect>Introduction

+

+<sect1>The Distributed Multihead X Server

+

+<p>Current Open Source multihead solutions are limited to a single

+physical machine.  A single X server controls multiple display devices,

+which can be arranged as independent heads or unified into a single

+desktop (with Xinerama).  These solutions are limited to the number of

+physical devices that can co-exist in a single machine (e.g., due to the

+number of AGP/PCI slots available for graphics cards).  Thus, large

+tiled displays are not currently possible.  The work described in this

+paper will eliminate the requirement that the display devices reside in

+the same physical machine.  This will be accomplished by developing a

+front-end proxy X server that will control multiple back-end X servers

+that make up the large display.

+

+<p>The overall structure of the distributed multihead X (DMX) project is

+as follows: A single front-end X server will act as a proxy to a set of

+back-end X servers, which handle all of the visible rendering.  X

+clients will connect to the front-end server just as they normally would

+to a regular X server.  The front-end server will present an abstracted

+view to the client of a single large display.  This will ensure that all

+standard X clients will continue to operate without modification

+(limited, as always, by the visuals and extensions provided by the X

+server).  Clients that are DMX-aware will be able to use an extension to

+obtain information about the back-end servers (e.g., for placement of

+pop-up windows, window alignments by the window manager, etc.).

+

+<p>The architecture of the DMX server is divided into two main sections:

+input (e.g., mouse and keyboard events) and output (e.g., rendering and

+windowing requests).  Each of these are describe briefly below, and the

+rest of this design document will describe them in greater detail.

+

+<p>The DMX server can receive input from three general types of input

+devices: "local" devices that are physically attached to the machine on

+which DMX is running, "backend" devices that are physically attached to

+one or more of the back-end X servers (and that generate events via the

+X protocol stream from the backend), and "console" devices that can be

+abstracted from any non-back-end X server.  Backend and console devices

+are treated differently because the pointer device on the back-end X

+server also controls the location of the hardware X cursor.  Full

+support for XInput extension devices is provided.

+

+<p>Rendering requests will be accepted by the front-end server; however,

+rendering to visible windows will be broken down as needed and sent to

+the appropriate back-end server(s) via X11 library calls for actual

+rendering.  The basic framework will follow a Xnest-style approach.  GC

+state will be managed in the front-end server and sent to the

+appropriate back-end server(s) as required.  Pixmap rendering will (at

+least initially) be handled by the front-end X server.  Windowing

+requests (e.g., ordering, mapping, moving, etc.) will handled in the

+front-end server.  If the request requires a visible change, the

+windowing operation will be translated into requests for the appropriate

+back-end server(s).  Window state will be mirrored in the back-end

+server(s) as needed.

+

+<sect1>Layout of Paper

+

+<p>The next section describes the general development plan that was

+actually used for implementation.  The final section discusses

+outstanding issues at the conclusion of development.  The first appendix

+provides low-level technical detail that may be of interest to those

+intimately familiar with the X server architecture.  The final appendix

+describes the four phases of development that were performed during the

+first two years of development.

+

+<p>The final year of work was divided into 9 tasks that are not

+described in specific sections of this document.  The major tasks during

+that time were the enhancement of the reconfiguration ability added in

+Phase IV, addition of support for a dynamic number of back-end displays

+(instead of a hard-coded limit), and the support for back-end display

+and input removal and addition.  This work is mentioned in this paper,

+but is not covered in detail.

+

+<!-- ============================================================ -->

+<sect>Development plan

+

+<p>This section describes the development plan from approximately June

+2001 through July 2003.

+

+<sect1>Bootstrap code

+

+<p>To allow for rapid development of the DMX server by multiple

+developers during the first development stage, the problem will be

+broken down into three tasks: the overall DMX framework, back-end

+rendering services and input device handling services.  However, before

+the work begins on these tasks, a simple framework that each developer

+could use was implemented to bootstrap the development effort.  This

+framework renders to a single back-end server and provides dummy input

+devices (i.e., the keyboard and mouse).  The simple back-end rendering

+service was implemented using the shadow framebuffer support currently

+available in the XFree86 environment.

+

+<p>Using this bootstrapping framework, each developer has been able to

+work on each of the tasks listed above independently as follows: the

+framework will be extended to handle arbitrary back-end server

+configurations; the back-end rendering services will be transitioned to

+the more efficient Xnest-style implementation; and, an input device

+framework to handle various input devices via the input extension will

+be developed.

+

+<p>Status: The boot strap code is complete.  <!-- August 2001 -->

+

+

+<sect1>Input device handling

+

+<p>An X server (including the front-end X server) requires two core

+input devices -- a keyboard and a pointer (mouse).  These core devices

+are handled and required by the core X11 protocol.  Additional types of

+input devices may be attached and utilized via the XInput extension.

+These are usually referred to as ``XInput extension devices'',

+

+<p>There are some options as to how the front-end X server gets its core

+input devices:

+

+<enum>

+    <item>Local Input. The physical input devices (e.g., keyboard and

+    mouse) can be attached directly to the front-end X server.  In this

+    case, the keyboard and mouse on the machine running the front-end X

+    server will be used.  The front-end will have drivers to read the

+    raw input from those devices and convert it into the required X

+    input events (e.g., key press/release, pointer button press/release,

+    pointer motion).  The front-end keyboard driver will keep track of

+    keyboard properties such as key and modifier mappings, autorepeat

+    state, keyboard sound and led state.  Similarly the front-end

+    pointer driver will keep track if pointer properties such as the

+    button mapping and movement acceleration parameters.  With this

+    option, input is handled fully in the front-end X server, and the

+    back-end X servers are used in a display-only mode.  This option was

+    implemented and works for a limited number of Linux-specific

+    devices.  Adding additional local input devices for other

+    architectures is expected to be relatively simple.

+

+    <p>The following options are available for implementing local input

+    devices:

+

+    <enum>

+        <item>The XFree86 X server has modular input drivers that could

+        be adapted for this purpose.  The mouse driver supports a wide

+        range of mouse types and interfaces, as well as a range of

+        Operating System platforms.  The keyboard driver in XFree86 is

+        not currently as modular as the mouse driver, but could be made

+        so.  The XFree86 X server also has a range of other input

+        drivers for extended input devices such as tablets and touch

+        screens.  Unfortunately, the XFree86 drivers are generally

+        complex, often simultaneously providing support for multiple

+        devices across multiple architectures; and rely so heavily on

+        XFree86-specific helper-functions, that this option was not

+        pursued.

+

+

+        <item>The <tt/kdrive/ X server in XFree86 has built-in drivers that

+        support PS/2 mice and keyboard under Linux.  The mouse driver

+        can indirectly handle other mouse types if the Linux utility

+        <tt/gpm/ is used as to translate the native mouse protocol into

+        PS/2 mouse format.  These drivers could be adapted and built in

+        to the front-end X server if this range of hardware and OS

+        support is sufficient.  While much simpler than the XFree86

+        drivers, the <tt/kdrive/ drivers were not used for the DMX

+        implementation.

+

+        <item>Reimplementation of keyboard and mouse drivers from

+        scratch for the DMX framework.  Because keyboard and mouse

+        drivers are relatively trivial to implement, this pathway was

+        selected.  Other drivers in the X source tree were referenced,

+        and significant contributions from other drivers are noted in

+        the DMX source code.

+    </enum>

+

+    <item>Backend Input.  The front-end can make use of the core input

+    devices attached to one or more of the back-end X servers.  Core

+    input events from multiple back-ends are merged into a single input

+    event stream.  This can work sanely when only a single set of input

+    devices is used at any given time.  The keyboard and pointer state

+    will be handled in the front-end, with changes propagated to the

+    back-end servers as needed.  This option was implemented and works

+    well.  Because the core pointer on a back-end controls the hardware

+    mouse on that back-end, core pointers cannot be treated as XInput

+    extension devices.  However, all back-end XInput extensions devices

+    can be mapped to either DMX core or DMX XInput extension devices.

+

+    <item>Console Input.  The front-end server could create a console

+    window that is displayed on an X server independent of the back-end

+    X servers.  This console window could display things like the

+    physical screen layout, and the front-end could get its core input

+    events from events delivered to the console window.  This option was

+    implemented and works well.  To help the human navigate, window

+    outlines are also displayed in the console window.  Further, console

+    windows can be used as either core or XInput extension devices.

+

+    <item>Other options were initially explored, but they were all

+    partial subsets of the options listed above and, hence, are

+    irrelevant.

+

+</enum>

+

+<p>Although extended input devices are not specifically mentioned in the

+Distributed X requirements, the options above were all implemented so

+that XInput extension devices were supported.

+

+<p>The bootstrap code (Xdmx) had dummy input devices, and these are

+still supported in the final version.  These do the necessary

+initialization to satisfy the X server's requirements for core pointer

+and keyboard devices, but no input events are ever generated.

+

+<p>Status: The input code is complete.  Because of the complexity of the

+XFree86 input device drivers (and their heavy reliance on XFree86

+infrastructure), separate low-level device drivers were implemented for

+Xdmx.  The following kinds of drivers are supported (in general, the

+devices can be treated arbitrarily as "core" input devices or as XInput

+"extension" devices; and multiple instances of different kinds of

+devices can be simultaneously available):

+    <enum>

+        <item> A "dummy" device drive that never generates events.

+

+        <item> "Local" input is from the low-level hardware on which the

+        Xdmx binary is running.  This is the only area where using the

+        XFree86 driver infrastructure would have been helpful, and then

+        only partially, since good support for generic USB devices does

+        not yet exist in XFree86 (in any case, XFree86 and kdrive driver

+        code was used where possible).  Currently, the following local

+        devices are supported under Linux (porting to other operating

+        systems should be fairly straightforward):

+        <itemize>

+            <item>Linux keyboard

+            <item>Linux serial mouse (MS)

+            <item>Linux PS/2 mouse

+            <item>USB keyboard

+            <item>USB mouse

+            <item>USB generic device (e.g., joystick, gamepad, etc.)

+        </itemize>

+

+        <item> "Backend" input is taken from one or more of the back-end

+        displays.  In this case, events are taken from the back-end X

+        server and are converted to Xdmx events.  Care must be taken so

+        that the sprite moves properly on the display from which input

+        is being taken.

+

+        <item> "Console" input is taken from an X window that Xdmx

+        creates on the operator's display (i.e., on the machine running

+        the Xdmx binary).  When the operator's mouse is inside the

+        console window, then those events are converted to Xdmx events.

+        Several special features are available: the console can display

+        outlines of windows that are on the Xdmx display (to facilitate

+        navigation), the cursor can be confined to the console, and a

+        "fine" mode can be activated to allow very precise cursor

+        positioning.

+    </enum>

+

+

+<!-- May 2002; July 2003 -->

+

+<sect1>Output device handling

+

+<p>The output of the DMX system displays rendering and windowing

+requests across multiple screens.  The screens are typically arranged in

+a grid such that together they represent a single large display.

+

+<p>The output section of the DMX code consists of two parts.  The first

+is in the front-end proxy X server (Xdmx), which accepts client

+connections, manages the windows, and potentially renders primitives but

+does not actually display any of the drawing primitives.  The second

+part is the back-end X server(s), which accept commands from the

+front-end server and display the results on their screens.

+

+<sect2>Initialization

+

+<p>The DMX front-end must first initialize its screens by connecting to

+each of the back-end X servers and collecting information about each of

+these screens.  However, the information collected from the back-end X

+servers might be inconsistent.  Handling these cases can be difficult

+and/or inefficient.  For example, a two screen system has one back-end X

+server running at 16bpp while the second is running at 32bpp.

+Converting rendering requests (e.g., XPutImage() or XGetImage()

+requests) to the appropriate bit depth can be very time consuming.

+Analyzing these cases to determine how or even if it is possible to

+handle them is required.  The current Xinerama code handles many of

+these cases (e.g., in PanoramiXConsolidate()) and will be used as a

+starting point.  In general, the best solution is to use homogeneous X

+servers and display devices.  Using back-end servers with the same depth

+is a requirement of the final DMX implementation.

+

+<p>Once this screen consolidation is finished, the relative position of

+each back-end X server's screen in the unified screen is initialized.  A

+full-screen window is opened on each of the back-end X servers, and the

+cursor on each screen is turned off.  The final DMX implementation can

+also make use of a partial-screen window, or multiple windows per

+back-end screen.

+

+<sect2>Handling rendering requests

+

+<p>After initialization, X applications connect to the front-end server.

+There are two possible implementations of how rendering and windowing

+requests are handled in the DMX system:

+

+<enum>

+    <item>A shadow framebuffer is used in the front-end server as the

+    render target.  In this option, all protocol requests are completely

+    handled in the front-end server.  All state and resources are

+    maintained in the front-end including a shadow copy of the entire

+    framebuffer.  The framebuffers attached to the back-end servers are

+    updated by XPutImage() calls with data taken directly from the

+    shadow framebuffer.

+

+    <p>This solution suffers from two main problems.  First, it does not

+    take advantage of any accelerated hardware available in the system.

+    Second, the size of the XPutImage() calls can be quite large and

+    thus will be limited by the bandwidth available.

+

+    <p>The initial DMX implementation used a shadow framebuffer by

+    default.

+

+    <item>Rendering requests are sent to each back-end server for

+    handling (as is done in the Xnest server described above).  In this

+    option, certain protocol requests are handled in the front-end

+    server and certain requests are repackaged and then sent to the

+    back-end servers.  The framebuffer is distributed across the

+    multiple back-end servers.  Rendering to the framebuffer is handled

+    on each back-end and can take advantage of any acceleration

+    available on the back-end servers' graphics display device.  State

+    is maintained both in the front and back-end servers.

+

+    <p>This solution suffers from two main drawbacks.  First, protocol

+    requests are sent to all back-end servers -- even those that will

+    completely clip the rendering primitive -- which wastes bandwidth

+    and processing time.  Second, state is maintained both in the front-

+    and back-end servers.  These drawbacks are not as severe as in

+    option 1 (above) and can either be overcome through optimizations or

+    are acceptable.  Therefore, this option will be used in the final

+    implementation.

+

+    <p>The final DMX implementation defaults to this mechanism, but also

+    supports the shadow framebuffer mechanism.  Several optimizations

+    were implemented to eliminate the drawbacks of the default

+    mechanism.  These optimizations are described the section below and

+    in Phase II of the Development Results (see appendix).

+

+</enum>

+

+<p>Status: Both the shadow framebuffer and Xnest-style code is complete.

+<!-- May 2002 -->

+

+

+<sect1>Optimizing DMX

+

+<p>Initially, the Xnest-style solution's performance will be measured

+and analyzed to determine where the performance bottlenecks exist.

+There are four main areas that will be addressed.

+

+<p>First, to obtain reasonable interactivity with the first development

+phase, XSync() was called after each protocol request.  The XSync()

+function flushes any pending protocol requests.  It then waits for the

+back-end to process the request and send a reply that the request has

+completed.  This happens with each back-end server and performance

+greatly suffers.  As a result of the way XSync() is called in the first

+development phase, the batching that the X11 library performs is

+effectively defeated.  The XSync() call usage will be analyzed and

+optimized by batching calls and performing them at regular intervals,

+except where interactivity will suffer (e.g., on cursor movements).

+

+<p>Second, the initial Xnest-style solution described above sends the

+repackaged protocol requests to all back-end servers regardless of

+whether or not they would be completely clipped out.  The requests that

+are trivially rejected on the back-end server wastes the limited

+bandwidth available.  By tracking clipping changes in the DMX X server's

+windowing code (e.g., by opening, closing, moving or resizing windows),

+we can determine whether or not back-end windows are visible so that

+trivial tests in the front-end server's GC ops drawing functions can

+eliminate these unnecessary protocol requests.

+

+<p>Third, each protocol request will be analyzed to determine if it is

+possible to break the request into smaller pieces at display boundaries.

+The initial ones to be analyzed are put and get image requests since

+they will require the greatest bandwidth to transmit data between the

+front and back-end servers.  Other protocol requests will be analyzed

+and those that will benefit from breaking them into smaller requests

+will be implemented.

+

+<p>Fourth, an extension is being considered that will allow font glyphs to

+be transferred from the front-end DMX X server to each back-end server.

+This extension will permit the front-end to handle all font requests and

+eliminate the requirement that all back-end X servers share the exact

+same fonts as the front-end server.  We are investigating the

+feasibility of this extension during this development phase.

+

+<p>Other potential optimizations will be determined from the performance

+analysis.

+

+<p>Please note that in our initial design, we proposed optimizing BLT

+operations (e.g., XCopyArea() and window moves) by developing an

+extension that would allow individual back-end servers to directly copy

+pixel data to other back-end servers.  This potential optimization was

+in response to the simple image movement implementation that required

+potentially many calls to GetImage() and PutImage().  However, the

+current Xinerama implementation handles these BLT operations

+differently.  Instead of copying data to and from screens, they generate

+expose events -- just as happens in the case when a window is moved from

+off a screen to on screen.  This approach saves the limited bandwidth

+available between front and back-end servers and is being standardized

+with Xinerama.  It also eliminates the potential setup problems and

+security issues resulting from having each back-end server open

+connections to all other back-end servers.  Therefore, we suggest

+accepting Xinerama's expose event solution.

+

+<p>Also note that the approach proposed in the second and third

+optimizations might cause backing store algorithms in the back-end to be

+defeated, so a DMX X server configuration flag will be added to disable

+these optimizations.

+

+<p>Status: The optimizations proposed above are complete.  It was

+determined that the using the xfs font server was sufficient and

+creating a new mechanism to pass glyphs was redundant; therefore, the

+fourth optimization proposed above was not included in DMX.

+<!-- September 2002 -->

+

+

+<sect1>DMX X extension support

+

+<p>The DMX X server keeps track of all the windowing information on the

+back-end X servers, but does not currently export this information to

+any client applications.  An extension will be developed to pass the

+screen information and back-end window IDs to DMX-aware clients.  These

+clients can then use this information to directly connect to and render

+to the back-end windows.  Bypassing the DMX X server allows DMX-aware

+clients to break up complex rendering requests on their own and send

+them directly to the windows on the back-end server's screens.  An

+example of a client that can make effective use of this extension is

+Chromium.

+

+<p>Status: The extension, as implemented, is fully documented in

+"Client-to-Server DMX Extension to the X Protocol".  Future changes

+might be required based on feedback and other proposed enhancements to

+DMX.  Currently, the following facilities are supported:

+<enum>

+    <item>

+        Screen information (clipping rectangle for each screen relative

+        to the virtual screen)

+    <item>

+        Window information (window IDs and clipping information for each

+        back-end window that corresponds to each DMX window)

+    <item>

+        Input device information (mappings from DMX device IDs to

+        back-end device IDs)

+    <item>

+        Force window creation (so that a client can override the

+        server-side lazy window creation optimization)

+    <item>

+        Reconfiguration (so that a client can request that a screen

+        position be changed)

+    <item>

+        Addition and removal of back-end servers and back-end and

+        console inputs.

+</enum>

+<!-- September 2002; July 2003 -->

+

+

+<sect1>Common X extension support

+

+<p>The XInput, XKeyboard and Shape extensions are commonly used

+extensions to the base X11 protocol.  XInput allows multiple and

+non-standard input devices to be accessed simultaneously.  These input

+devices can be connected to either the front-end or back-end servers.

+XKeyboard allows much better keyboard mappings control.  Shape adds

+support for arbitrarily shaped windows and is used by various window

+managers.  Nearly all potential back-end X servers make these extensions

+available, and support for each one will be added to the DMX system.

+

+<p>In addition to the extensions listed above, support for the X

+Rendering extension (Render) is being developed.  Render adds digital

+image composition to the rendering model used by the X Window System.

+While this extension is still under development by Keith Packard of HP,

+support for the current version will be added to the DMX system.

+

+<p>Support for the XTest extension was added during the first

+development phase.

+

+<!-- WARNING: this list is duplicated in the Phase IV discussion -->

+<p>Status: The following extensions are supported and are discussed in

+more detail in Phase IV of the Development Results (see appendix):

+    BIG-REQUESTS,

+    DEC-XTRAP,

+

+<sect1>OpenGL support

+

+<p>OpenGL support using the Mesa code base exists in XFree86 release 4

+and later.  Currently, the direct rendering infrastructure (DRI)

+provides accelerated OpenGL support for local clients and unaccelerated

+OpenGL support (i.e., software rendering) is provided for non-local

+clients.

+

+<p>The single head OpenGL support in XFree86 4.x will be extended to use

+the DMX system.  When the front and back-end servers are on the same

+physical hardware, it is possible to use the DRI to directly render to

+the back-end servers.  First, the existing DRI will be extended to

+support multiple display heads, and then to support the DMX system.

+OpenGL rendering requests will be direct rendering to each back-end X

+server.  The DRI will request the screen layout (either from the

+existing Xinerama extension or a DMX-specific extension).  Support for

+synchronized swap buffers will also be added (on hardware that supports

+it).  Note that a single front-end server with a single back-end server

+on the same physical machine can emulate accelerated indirect rendering.

+

+<p>When the front and back-end servers are on different physical

+hardware or are using non-XFree86 4.x X servers, a mechanism to render

+primitives across the back-end servers will be provided.  There are

+several options as to how this can be implemented.

+

+<enum>

+    <item>The existing OpenGL support in each back-end server can be

+    used by repackaging rendering primitives and sending them to each

+    back-end server.  This option is similar to the unoptimized

+    Xnest-style approach mentioned above.  Optimization of this solution

+    is beyond the scope of this project and is better suited to other

+    distributed rendering systems.

+

+    <item>Rendering to a pixmap in the front-end server using the

+    current XFree86 4.x code, and then displaying to the back-ends via

+    calls to XPutImage() is another option.  This option is similar to

+    the shadow frame buffer approach mentioned above.  It is slower and

+    bandwidth intensive, but has the advantage that the back-end servers

+    are not required to have OpenGL support.

+</enum>

+

+<p>These, and other, options will be investigated in this phase of the

+work.

+

+<p>Work by others have made Chromium DMX-aware.  Chromium will use the

+DMX X protocol extension to obtain information about the back-end

+servers and will render directly to those servers, bypassing DMX.

+

+<p>Status: OpenGL support by the glxProxy extension was implemented by

+SGI and has been integrated into the DMX code base.

+<!-- May 2003-->

+

+

+<!-- ============================================================ -->

+<sect>Current issues

+

+<p>In this sections the current issues are outlined that require further

+investigation.

+

+<sect1>Fonts

+

+<p>The font path and glyphs need to be the same for the front-end and

+each of the back-end servers.  Font glyphs could be sent to the back-end

+servers as necessary but this would consume a significant amount of

+available bandwidth during font rendering for clients that use many

+different fonts (e.g., Netscape).  Initially, the font server (xfs) will

+be used to provide the fonts to both the front-end and back-end servers.

+Other possibilities will be investigated during development.

+

+<sect1>Zero width rendering primitives

+

+<p>To allow pixmap and on-screen rendering to be pixel perfect, all

+back-end servers must render zero width primitives exactly the same as

+the front-end renders the primitives to pixmaps.  For those back-end

+servers that do not exactly match, zero width primitives will be

+automatically converted to one width primitives.  This can be handled in

+the front-end server via the GC state.

+

+<sect1>Output scaling

+

+<p>With very large tiled displays, it might be difficult to read the

+information on the standard X desktop.  In particular, the cursor can be

+easily lost and fonts could be difficult to read.  Automatic primitive

+scaling might prove to be very useful.  We will investigate the

+possibility of scaling the cursor and providing a set of alternate

+pre-scaled fonts to replace the standard fonts that many applications

+use (e.g., fixed).  Other options for automatic scaling will also be

+investigated.

+

+<sect1>Per-screen colormaps

+

+<p>Each screen's default colormap in the set of back-end X servers

+should be able to be adjusted via a configuration utility.  This support

+is would allow the back-end screens to be calibrated via custom gamma

+tables.  On 24-bit systems that support a DirectColor visual, this type

+of correction can be accommodated.  One possible implementation would be

+to advertise to X client of the DMX server a TrueColor visual while

+using DirectColor visuals on the back-end servers to implement this type

+of color correction.  Other options will be investigated.

+

+<!-- ============================================================ -->

+<appendix>

+

+<sect>Background

+

+<p>This section describes the existing Open Source architectures that

+can be used to handle multiple screens and upon which this development

+project is based.  This section was written before the implementation

+was finished, and may not reflect actual details of the implementation.

+It is left for historical interest only.

+

+<sect1>Core input device handling

+

+<p>The following is a description of how core input devices are handled

+by an X server.

+

+<sect2>InitInput()

+

+<p>InitInput() is a DDX function that is called at the start of each

+server generation from the X server's main() function.  Its purpose is

+to determine what input devices are connected to the X server, register

+them with the DIX and MI layers, and initialize the input event queue.

+InitInput() does not have a return value, but the X server will abort if

+either a core keyboard device or a core pointer device are not

+registered.  Extended input (XInput) devices can also be registered in

+InitInput().

+

+<p>InitInput() usually has implementation specific code to determine

+which input devices are available.  For each input device it will be

+using, it calls AddInputDevice():

+

+<descrip>

+<tag/AddInputDevice()/ This DIX function allocates the device structure,

+registers a callback function (which handles device init, close, on and

+off), and returns the input handle, which can be treated as opaque.  It

+is called once for each input device.

+</descrip>

+

+<p>Once input handles for core keyboard and core pointer devices have

+been obtained from AddInputDevice(), they are registered as core devices

+by calling RegisterPointerDevice() and RegisterKeyboardDevice().  Each

+of these should be called once.  If both core devices are not

+registered, then the X server will exit with a fatal error when it

+attempts to start the input devices in InitAndStartDevices(), which is

+called directly after InitInput() (see below).

+

+<descrip>

+<tag/Register{Pointer,Keyboard}Device()/ These DIX functions take a

+handle returned from AddInputDevice() and initialize the core input

+device fields in inputInfo, and initialize the input processing and grab

+functions for each core input device.

+</descrip>

+

+<p>The core pointer device is then registered with the miPointer code

+(which does the high level cursor handling).  While this registration

+is not necessary for correct miPointer operation in the current XFree86

+code, it is still done mostly for compatibility reasons.

+

+<descrip>

+<tag/miRegisterPointerDevice()/ This MI function registers the core

+pointer's input handle with with the miPointer code.

+</descrip>

+

+<p>The final part of InitInput() is the initialization of the input

+event queue handling.  In most cases, the event queue handling provided

+in the MI layer is used.  The primary XFree86 X server uses its own

+event queue handling to support some special cases related to the XInput

+extension and the XFree86-specific DGA extension.  For our purposes, the

+MI event queue handling should be suitable.  It is initialized by

+calling mieqInit():

+

+<descrip>

+<tag/mieqInit()/ This MI function initializes the MI event queue for the

+core devices, and is passed the public component of the input handles

+for the two core devices.

+</descrip>

+

+<p>If a wakeup handler is required to deliver synchronous input

+events, it can be registered here by calling the DIX function

+RegisterBlockAndWakeupHandlers().  (See the devReadInput() description

+below.)

+

+<sect2>InitAndStartDevices()

+

+<p>InitAndStartDevices() is a DIX function that is called immediately

+after InitInput() from the X server's main() function.  Its purpose is

+to initialize each input device that was registered with

+AddInputDevice(), enable each input device that was successfully

+initialized, and create the list of enabled input devices.  Once each

+registered device is processed in this way, the list of enabled input

+devices is checked to make sure that both a core keyboard device and

+core pointer device were registered and successfully enabled.  If not,

+InitAndStartDevices() returns failure, and results in the the X server

+exiting with a fatal error.

+

+<p>Each registered device is initialized by calling its callback

+(dev-&gt;deviceProc) with the DEVICE_INIT argument:

+

+<descrip>

+<tag/(*dev-&gt;deviceProc)(dev, DEVICE_INIT)/ This function initializes the

+device structs with core information relevant to the device.

+

+<p>For pointer devices, this means specifying the number of buttons,

+default button mapping, the function used to get motion events (usually

+miPointerGetMotionEvents()), the function used to change/control the

+core pointer motion parameters (acceleration and threshold), and the

+motion buffer size.

+

+<p>For keyboard devices, this means specifying the keycode range,

+default keycode to keysym mapping, default modifier mapping, and the

+functions used to sound the keyboard bell and modify/control the

+keyboard parameters (LEDs, bell pitch and duration, key click, which

+keys are auto-repeating, etc).

+</descrip>

+

+<p>Each initialized device is enabled by calling EnableDevice():

+

+<descrip>

+<tag/EnableDevice()/ EnableDevice() calls the device callback with

+DEVICE_ON:

+    <descrip>

+    <tag/(*dev-&gt;deviceProc)(dev, DEVICE_ON)/ This typically opens and

+    initializes the relevant physical device, and when appropriate,

+    registers the device's file descriptor (or equivalent) as a valid

+    input source.

+    </descrip>

+

+    <p>EnableDevice() then adds the device handle to the X server's

+    global list of enabled devices.

+</descrip>

+

+<p>InitAndStartDevices() then verifies that a valid core keyboard and

+pointer has been initialized and enabled.  It returns failure if either

+are missing.

+

+<sect2>devReadInput()

+

+<p>Each device will have some function that gets called to read its

+physical input.  These may be called in a number of different ways.  In

+the case of synchronous I/O, they will be called from a DDX

+wakeup-handler that gets called after the server detects that new input is

+available.  In the case of asynchronous I/O, they will be called from a

+(SIGIO) signal handler triggered when new input is available.  This

+function should do at least two things: make sure that input events get

+enqueued, and make sure that the cursor gets moved for motion events

+(except if these are handled later by the driver's own event queue

+processing function, which cannot be done when using the MI event queue

+handling).

+

+<p>Events are queued by calling mieqEnqueue():

+

+<descrip>

+<tag/mieqEnqueue()/ This MI function is used to add input events to the

+event queue.  It is simply passed the event to be queued.

+</descrip>

+

+<p>The cursor position should be updated when motion events are

+enqueued, by calling either miPointerAbsoluteCursor() or

+miPointerDeltaCursor():

+

+<descrip>

+<tag/miPointerAbsoluteCursor()/ This MI function is used to move the

+cursor to the absolute coordinates provided.

+<tag/miPointerDeltaCursor()/ This MI function is used to move the cursor

+relative to its current position.

+</descrip>

+

+<sect2>ProcessInputEvents()

+

+<p>ProcessInputEvents() is a DDX function that is called from the X

+server's main dispatch loop when new events are available in the input

+event queue.  It typically processes the enqueued events, and updates

+the cursor/pointer position.  It may also do other DDX-specific event

+processing.

+

+<p>Enqueued events are processed by mieqProcessInputEvents() and passed

+to the DIX layer for transmission to clients:

+

+<descrip>

+<tag/mieqProcessInputEvents()/ This function processes each event in the

+event queue, and passes it to the device's input processing function.

+The DIX layer provides default functions to do this processing, and they

+handle the task of getting the events passed back to the relevant

+clients.

+<tag/miPointerUpdate()/ This function resynchronized the cursor position

+with the new pointer position.  It also takes care of moving the cursor

+between screens when needed in multi-head configurations.

+</descrip>

+

+

+<sect2>DisableDevice()

+

+<p>DisableDevice is a DIX function that removes an input device from the

+list of enabled devices.  The result of this is that the device no

+longer generates input events.  The device's data structures are kept in

+place, and disabling a device like this can be reversed by calling

+EnableDevice().  DisableDevice() may be called from the DDX when it is

+desirable to do so (e.g., the XFree86 server does this when VT

+switching).  Except for special cases, this is not normally called for

+core input devices.

+

+<p>DisableDevice() calls the device's callback function with

+<tt/DEVICE_OFF/:

+

+<descrip>

+<tag/(*dev-&gt;deviceProc)(dev, DEVICE_OFF)/ This typically closes the

+relevant physical device, and when appropriate, unregisters the device's

+file descriptor (or equivalent) as a valid input source.

+</descrip>

+

+<p>DisableDevice() then removes the device handle from the X server's

+global list of enabled devices.

+

+

+<sect2>CloseDevice()

+

+<p>CloseDevice is a DIX function that removes an input device from the

+list of available devices.  It disables input from the device and frees

+all data structures associated with the device.  This function is

+usually called from CloseDownDevices(), which is called from main() at

+the end of each server generation to close all input devices.

+

+<p>CloseDevice() calls the device's callback function with

+<tt/DEVICE_CLOSE/:

+

+<descrip>

+<tag/(*dev-&gt;deviceProc)(dev, DEVICE_CLOSE)/ This typically closes the

+relevant physical device, and when appropriate, unregisters the device's

+file descriptor (or equivalent) as a valid input source.  If any device

+specific data structures were allocated when the device was initialized,

+they are freed here.

+</descrip>

+

+<p>CloseDevice() then frees the data structures that were allocated

+for the device when it was registered/initialized.

+

+

+<sect2>LegalModifier()

+<!-- dmx/dmxinput.c - currently returns TRUE -->           

+<p>LegalModifier() is a required DDX function that can be used to

+restrict which keys may be modifier keys.  This seems to be present for

+historical reasons, so this function should simply return TRUE

+unconditionally.

+

+

+<sect1>Output handling

+

+<p>The following sections describe the main functions required to

+initialize, use and close the output device(s) for each screen in the X

+server.

+

+<sect2>InitOutput()

+

+<p>This DDX function is called near the start of each server generation

+from the X server's main() function.  InitOutput()'s main purpose is to

+initialize each screen and fill in the global screenInfo structure for

+each screen.  It is passed three arguments: a pointer to the screenInfo

+struct, which it is to initialize, and argc and argv from main(), which

+can be used to determine additional configuration information.

+

+<p>The primary tasks for this function are outlined below:

+

+<enum>

+    <item><bf/Parse configuration info:/ The first task of InitOutput()

+    is to parses any configuration information from the configuration

+    file.  In addition to the XF86Config file, other configuration

+    information can be taken from the command line.  The command line

+    options can be gathered either in InitOutput() or earlier in the

+    ddxProcessArgument() function, which is called by

+    ProcessCommandLine().  The configuration information determines the

+    characteristics of the screen(s).  For example, in the XFree86 X

+    server, the XF86Config file specifies the monitor information, the

+    screen resolution, the graphics devices and slots in which they are

+    located, and, for Xinerama, the screens' layout.

+

+    <item><bf/Initialize screen info:/ The next task is to initialize

+    the screen-dependent internal data structures.  For example, part of

+    what the XFree86 X server does is to allocate its screen and pixmap

+    private indices, probe for graphics devices, compare the probed

+    devices to the ones listed in the XF86Config file, and add the ones that

+    match to the internal xf86Screens&lsqb;&rsqb; structure.

+

+    <item><bf/Set pixmap formats:/ The next task is to initialize the

+    screenInfo's image byte order, bitmap bit order and bitmap scanline

+    unit/pad.  The screenInfo's pixmap format's depth, bits per pixel

+    and scanline padding is also initialized at this stage.

+

+    <item><bf/Unify screen info:/ An optional task that might be done at

+    this stage is to compare all of the information from the various

+    screens and determines if they are compatible (i.e., if the set of

+    screens can be unified into a single desktop).  This task has

+    potential to be useful to the DMX front-end server, if Xinerama's

+    PanoramiXConsolidate() function is not sufficient.

+</enum>

+

+<p>Once these tasks are complete, the valid screens are known and each

+of these screens can be initialized by calling AddScreen().

+

+<sect2>AddScreen()

+

+<p>This DIX function is called from InitOutput(), in the DDX layer, to

+add each new screen to the screenInfo structure.  The DDX screen

+initialization function and command line arguments (i.e., argc and argv)

+are passed to it as arguments.

+

+<p>This function first allocates a new Screen structure and any privates

+that are required.  It then initializes some of the fields in the Screen

+struct and sets up the pixmap padding information.  Finally, it calls

+the DDX screen initialization function ScreenInit(), which is described

+below.  It returns the number of the screen that were just added, or -1

+if there is insufficient memory to add the screen or if the DDX screen

+initialization fails.

+

+<sect2>ScreenInit()

+

+<p>This DDX function initializes the rest of the Screen structure with

+either generic or screen-specific functions (as necessary).  It also

+fills in various screen attributes (e.g., width and height in

+millimeters, black and white pixel values).

+

+<p>The screen init function usually calls several functions to perform

+certain screen initialization functions.  They are described below:

+

+<descrip>

+<tag/{mi,*fb}ScreenInit()/ The DDX layer's ScreenInit() function usually

+calls another layer's ScreenInit() function (e.g., miScreenInit() or

+fbScreenInit()) to initialize the fallbacks that the DDX driver does not

+specifically handle.

+

+<p>After calling another layer's ScreenInit() function, any

+screen-specific functions either wrap or replace the other layer's

+function pointers.  If a function is to be wrapped, each of the old

+function pointers from the other layer are stored in a screen private

+area.  Common functions to wrap are CloseScreen() and SaveScreen().

+

+<tag/miInitializeBackingStore()/ This MI function initializes the

+screen's backing storage functions, which are used to save areas of

+windows that are currently covered by other windows.

+

+<tag/miDCInitialize()/ This MI function initializes the MI cursor

+display structures and function pointers.  If a hardware cursor is used,

+the DDX layer's ScreenInit() function will wrap additional screen and

+the MI cursor display function pointers.

+</descrip>

+

+<p>Another common task for ScreenInit() function is to initialize the

+output device state.  For example, in the XFree86 X server, the

+ScreenInit() function saves the original state of the video card and

+then initializes the video mode of the graphics device.

+

+<sect2>CloseScreen()

+

+<p>This function restores any wrapped screen functions (and in

+particular the wrapped CloseScreen() function) and restores the state of

+the output device to its original state.  It should also free any

+private data it created during the screen initialization.

+

+<sect2>GC operations

+

+<p>When the X server is requested to render drawing primitives, it does

+so by calling drawing functions through the graphics context's operation

+function pointer table (i.e., the GCOps functions).  These functions

+render the basic graphics operations such as drawing rectangles, lines,

+text or copying pixmaps.  Default routines are provided either by the MI

+layer, which draws indirectly through a simple span interface, or by the

+framebuffer layers (e.g., CFB, MFB, FB), which draw directly to a

+linearly mapped frame buffer.

+

+<p>To take advantage of special hardware on the graphics device,

+specific GCOps functions can be replaced by device specific code.

+However, many times the graphics devices can handle only a subset of the

+possible states of the GC, so during graphics context validation,

+appropriate routines are selected based on the state and capabilities of

+the hardware.  For example, some graphics hardware can accelerate single

+pixel width lines with certain dash patterns.  Thus, for dash patterns

+that are not supported by hardware or for width 2 or greater lines, the

+default routine is chosen during GC validation.

+

+<p>Note that some pointers to functions that draw to the screen are

+stored in the Screen structure.  They include GetImage(), GetSpans(),

+CopyWindow() and RestoreAreas().

+

+<sect2>Xnest

+

+<p>The Xnest X server is a special proxy X server that relays the X

+protocol requests that it receives to a ``real'' X server that then

+processes the requests and displays the results, if applicable.  To the X

+applications, Xnest appears as if it is a regular X server.  However,

+Xnest is both server to the X application and client of the real X

+server, which will actually handle the requests.

+

+<p>The Xnest server implements all of the standard input and output

+initialization steps outlined above.

+

+<descrip>

+<tag/InitOutput()/ Xnest takes its configuration information from

+command line arguments via ddxProcessArguments().  This information

+includes the real X server display to connect to, its default visual

+class, the screen depth, the Xnest window's geometry, etc.  Xnest then

+connects to the real X server and gathers visual, colormap, depth and

+pixmap information about that server's display, creates a window on that

+server, which will be used as the root window for Xnest.

+

+<p>Next, Xnest initializes its internal data structures and uses the

+data from the real X server's pixmaps to initialize its own pixmap

+formats.  Finally, it calls AddScreen(xnestOpenScreen, argc, argv) to

+initialize each of its screens.

+

+<tag/ScreenInit()/ Xnest's ScreenInit() function is called

+xnestOpenScreen().  This function initializes its screen's depth and

+visual information, and then calls miScreenInit() to set up the default

+screen functions.  It then calls miInitializeBackingStore() and

+miDCInitialize() to initialize backing store and the software cursor.

+Finally, it replaces many of the screen functions with its own

+functions that repackage and send the requests to the real X server to

+which Xnest is attached.

+

+<tag/CloseScreen()/ This function frees its internal data structure

+allocations.  Since it replaces instead of wrapping screen functions,

+there are no function pointers to unwrap.  This can potentially lead to

+problems during server regeneration.

+

+<tag/GC operations/ The GC operations in Xnest are very simple since

+they leave all of the drawing to the real X server to which Xnest is

+attached.  Each of the GCOps takes the request and sends it to the

+real X server using standard Xlib calls.  For example, the X

+application issues a XDrawLines() call.  This function turns into a

+protocol request to Xnest, which calls the xnestPolylines() function

+through Xnest's GCOps function pointer table.  The xnestPolylines()

+function is only a single line, which calls XDrawLines() using the same

+arguments that were passed into it.  Other GCOps functions are very

+similar.  Two exceptions to the simple GCOps functions described above

+are the image functions and the BLT operations.

+

+<p>The image functions, GetImage() and PutImage(), must use a temporary

+image to hold the image to be put of the image that was just grabbed

+from the screen while it is in transit to the real X server or the

+client.  When the image has been transmitted, the temporary image is

+destroyed.

+

+<p>The BLT operations, CopyArea() and CopyPlane(), handle not only the

+copy function, which is the same as the simple cases described above,

+but also the graphics exposures that result when the GC's graphics

+exposure bit is set to True.  Graphics exposures are handled in a helper

+function, xnestBitBlitHelper().  This function collects the exposure

+events from the real X server and, if any resulting in regions being

+exposed, then those regions are passed back to the MI layer so that it

+can generate exposure events for the X application.

+</descrip>

+

+<p>The Xnest server takes its input from the X server to which it is

+connected.  When the mouse is in the Xnest server's window, keyboard and

+mouse events are received by the Xnest server, repackaged and sent back

+to any client that requests those events.

+

+<sect2>Shadow framebuffer

+

+<p>The most common type of framebuffer is a linear array memory that

+maps to the video memory on the graphics device.  However, accessing

+that video memory over an I/O bus (e.g., ISA or PCI) can be slow.  The

+shadow framebuffer layer allows the developer to keep the entire

+framebuffer in main memory and copy it back to video memory at regular

+intervals.  It also has been extended to handle planar video memory and

+rotated framebuffers.

+

+<p>There are two main entry points to the shadow framebuffer code:

+

+<descrip>

+<tag/shadowAlloc(width, height, bpp)/ This function allocates the in

+memory copy of the framebuffer of size width*height*bpp.  It returns a

+pointer to that memory, which will be used by the framebuffer

+ScreenInit() code during the screen's initialization.

+

+<tag/shadowInit(pScreen, updateProc, windowProc)/ This function

+initializes the shadow framebuffer layer.  It wraps several screen

+drawing functions, and registers a block handler that will update the

+screen.  The updateProc is a function that will copy the damaged regions

+to the screen, and the windowProc is a function that is used when the

+entire linear video memory range cannot be accessed simultaneously so

+that only a window into that memory is available (e.g., when using the

+VGA aperture).

+</descrip>

+

+<p>The shadow framebuffer code keeps track of the damaged area of each

+screen by calculating the bounding box of all drawing operations that

+have occurred since the last screen update.  Then, when the block handler

+is next called, only the damaged portion of the screen is updated.

+

+<p>Note that since the shadow framebuffer is kept in main memory, all

+drawing operations are performed by the CPU and, thus, no accelerated

+hardware drawing operations are possible.

+

+

+<sect1>Xinerama

+

+<p>Xinerama is an X extension that allows multiple physical screens

+controlled by a single X server to appear as a single screen.  Although

+the extension allows clients to find the physical screen layout via

+extension requests, it is completely transparent to clients at the core

+X11 protocol level.  The original public implementation of Xinerama came

+from Digital/Compaq.  XFree86 rewrote it, filling in some missing pieces

+and improving both X11 core protocol compliance and performance.  The

+Xinerama extension will be passing through X.Org's standardization

+process in the near future, and the sample implementation will be based

+on this rewritten version.

+

+<p>The current implementation of Xinerama is based primarily in the DIX

+(device independent) and MI (machine independent) layers of the X

+server.  With few exceptions the DDX layers do not need any changes to

+support Xinerama.  X server extensions often do need modifications to

+provide full Xinerama functionality.

+

+<p>The following is a code-level description of how Xinerama functions.

+

+<p>Note: Because the Xinerama extension was originally called the

+PanoramiX extension, many of the Xinerama functions still have the

+PanoramiX prefix.

+

+<descrip>

+    <tag/PanoramiXExtensionInit()/ PanoramiXExtensionInit() is a

+    device-independent extension function that is called at the start of

+    each server generation from InitExtensions(), which is called from

+    the X server's main() function after all output devices have been

+    initialized, but before any input devices have been initialized.

+

+    <p>PanoramiXNumScreens is set to the number of physical screens.  If

+    only one physical screen is present, the extension is disabled, and

+    PanoramiXExtensionInit() returns without doing anything else.

+

+    <p>The Xinerama extension is registered by calling AddExtension().

+    

+    <p>A local per-screen array of data structures

+    (panoramiXdataPtr&lsqb;&rsqb;)

+    is allocated for each physical screen, and GC and Screen private

+    indexes are allocated, and both GC and Screen private areas are

+    allocated for each physical screen.  These hold Xinerama-specific

+    per-GC and per-Screen data.  Each screen's CreateGC and CloseScreen

+    functions are wrapped by XineramaCreateGC() and

+    XineramaCloseScreen() respectively.  Some new resource classes are

+    created for Xinerama drawables and GCs, and resource types for

+    Xinerama windows, pixmaps and colormaps.

+

+    <p>A region (XineramaScreenRegions&lsqb;i&rsqb;) is initialized for each

+    physical screen, and single region (PanoramiXScreenRegion) is

+    initialized to be the union of the screen regions.  The

+    panoramiXdataPtr&lsqb;&rsqb; array is also initialized with the size and

+    origin of each screen.  The relative positioning information for the

+    physical screens is taken from the array

+    dixScreenOrigins&lsqb;&rsqb;, which

+    the DDX layer must initialize in InitOutput().  The bounds of the

+    combined screen is also calculated (PanoramiXPixWidth and

+    PanoramiXPixHeight).

+

+    <p>The DIX layer has a list of function pointers

+    (ProcVector&lsqb;&rsqb;) that

+    holds the entry points for the functions that process core protocol

+    requests.  The requests that Xinerama must intercept and break up

+    into physical screen-specific requests are wrapped.  The original

+    set is copied to SavedProcVector&lsqb;&rsqb;.  The types of requests

+    intercepted are Window requests, GC requests, colormap requests,

+    drawing requests, and some geometry-related requests.  This wrapping

+    allows the bulk of the protocol request processing to be handled

+    transparently to the DIX layer.  Some operations cannot be dealt with

+    in this way and are handled with Xinerama-specific code within the

+    DIX layer.

+

+    <tag/PanoramiXConsolidate()/ PanoramiXConsolidate() is a

+    device-independent extension function that is called directly from

+    the X server's main() function after extensions and input/output

+    devices have been initialized, and before the root windows are

+    defined and initialized.

+

+    <p>This function finds the set of depths (PanoramiXDepths&lsqb;&rsqb;) and

+    visuals (PanoramiXVisuals&lsqb;&rsqb;)

+    common to all of the physical screens.

+    PanoramiXNumDepths is set to the number of common depths, and

+    PanoramiXNumVisuals is set to the number of common visuals.

+    Resources are created for the single root window and the default

+    colormap.  Each of these resources has per-physical screen entries.

+

+    <tag/PanoramiXCreateConnectionBlock()/ PanoramiXConsolidate() is a

+    device-independent extension function that is called directly from

+    the X server's main() function after the per-physical screen root

+    windows are created.  It is called instead of the standard DIX

+    CreateConnectionBlock() function.  If this function returns FALSE,

+    the X server exits with a fatal error.  This function will return

+    FALSE if no common depths were found in PanoramiXConsolidate().

+    With no common depths, Xinerama mode is not possible.

+

+    <p>The connection block holds the information that clients get when

+    they open a connection to the X server.  It includes information

+    such as the supported pixmap formats, number of screens and the

+    sizes, depths, visuals, default colormap information, etc, for each

+    of the screens (much of information that <tt/xdpyinfo/ shows).  The

+    connection block is initialized with the combined single screen

+    values that were calculated in the above two functions.

+

+    <p>The Xinerama extension allows the registration of connection

+    block callback functions.  The purpose of these is to allow other

+    extensions to do processing at this point.  These callbacks can be

+    registered by calling XineramaRegisterConnectionBlockCallback() from

+    the other extension's ExtensionInit() function.  Each registered

+    connection block callback is called at the end of

+    PanoramiXCreateConnectionBlock().

+</descrip>

+

+<sect2>Xinerama-specific changes to the DIX code

+

+<p>There are a few types of Xinerama-specific changes within the DIX

+code.  The main ones are described here.

+

+<p>Functions that deal with colormap or GC -related operations outside of

+the intercepted protocol requests have a test added to only do the

+processing for screen numbers > 0.  This is because they are handled for

+the single Xinerama screen and the processing is done once for screen 0.

+

+<p>The handling of motion events does some coordinate translation between

+the physical screen's origin and screen zero's origin.  Also, motion

+events must be reported relative to the composite screen origin rather

+than the physical screen origins.

+

+<p>There is some special handling for cursor, window and event processing

+that cannot (either not at all or not conveniently) be done via the

+intercepted protocol requests.  A particular case is the handling of

+pointers moving between physical screens.

+

+<sect2>Xinerama-specific changes to the MI code

+

+<p>The only Xinerama-specific change to the MI code is in miSendExposures()

+to handle the coordinate (and window ID) translation for expose events.

+

+<sect2>Intercepted DIX core requests

+

+<p>Xinerama breaks up drawing requests for dispatch to each physical

+screen.  It also breaks up windows into pieces for each physical screen.

+GCs are translated into per-screen GCs.  Colormaps are replicated on

+each physical screen.  The functions handling the intercepted requests

+take care of breaking the requests and repackaging them so that they can

+be passed to the standard request handling functions for each screen in

+turn.  In addition, and to aid the repackaging, the information from

+many of the intercepted requests is used to keep up to date the

+necessary state information for the single composite screen.  Requests

+(usually those with replies) that can be satisfied completely from this

+stored state information do not call the standard request handling

+functions.

+

+<!-- ============================================================ -->

+

+<sect>Development Results

+

+<p>In this section the results of each phase of development are

+discussed.  This development took place between approximately June 2001

+and July 2003.

+

+<sect1>Phase I

+

+<p>The initial development phase dealt with the basic implementation

+including the bootstrap code, which used the shadow framebuffer, and the

+unoptimized implementation, based on an Xnest-style implementation.

+

+<sect2>Scope

+

+<p>The goal of Phase I is to provide fundamental functionality that can

+act as a foundation for ongoing work:

+<enum>

+    <item>Develop the proxy X server

+    <itemize>

+	<item>The proxy X server will operate on the X11 protocol and

+	relay requests as necessary to correctly perform the request.

+	<item>Work will be based on the existing work for Xinerama and

+	Xnest.

+	<item>Input events and windowing operations are handled in the

+	proxy server and rendering requests are repackaged and sent to

+	each of the back-end servers for display.

+	<item>The multiple screen layout (including support for

+	overlapping screens) will be user configurable via a

+	configuration file or through the configuration tool.

+    </itemize>

+    <item>Develop graphical configuration tool

+    <itemize>

+	<item>There will be potentially a large number of X servers to

+	configure into a single display.  The tool will allow the user

+	to specify which servers are involved in the configuration and

+	how they should be laid out.

+    </itemize>

+    <item>Pass the X Test Suite

+    <itemize>

+	<item>The X Test Suite covers the basic X11 operations.  All

+	tests known to succeed must correctly operate in the distributed

+	X environment.

+    </itemize>

+</enum>

+

+<p>For this phase, the back-end X servers are assumed to be unmodified X

+servers that do not support any DMX-related protocol extensions; future

+optimization pathways are considered, but are not implemented; and the

+configuration tool is assumed to rely only on libraries in the X source

+tree (e.g., Xt).

+

+<sect2>Results

+

+<p>The proxy X server, Xdmx, was developed to distribute X11 protocol

+requests to the set of back-end X servers.  It opens a window on each

+back-end server, which represents the part of the front-end's root

+window that is visible on that screen.  It mirrors window, pixmap and

+other state in each back-end server.  Drawing requests are sent to

+either windows or pixmaps on each back-end server.  This code is based

+on Xnest and uses the existing Xinerama extension.

+

+<p>Input events can be taken from (1) devices attached to the back-end

+server, (2) core devices attached directly to the Xdmx server, or (3)

+from a ``console'' window on another X server.  Events for these devices

+are gathered, processed and delivered to clients attached to the Xdmx

+server.

+

+<p>An intuitive configuration format was developed to help the user

+easily configure the multiple back-end X servers.  It was defined (see

+grammar in Xdmx man page) and a parser was implemented that is used by

+the Xdmx server and by a standalone xdmxconfig utility.  The parsing

+support was implemented such that it can be easily factored out of the X

+source tree for use with other tools (e.g., vdl).  Support for

+converting legacy vdl-format configuration files to the DMX format is

+provided by the vdltodmx utility.

+

+<p>Originally, the configuration file was going to be a subsection of

+XFree86's XF86Config file, but that was not possible since Xdmx is a

+completely separate X server.  Thus, a separate config file format was

+developed.  In addition, a graphical configuration

+tool, xdmxconfig, was developed to allow the user to create and arrange

+the screens in the configuration file.  The <bf/-configfile/ and <bf/-config/

+command-line options can be used to start Xdmx using a configuration

+file.

+

+<p>An extension that enables remote input testing is required for the X

+Test Suite to function.  During this phase, this extension (XTEST) was

+implemented in the Xdmx server.  The results from running the X Test

+Suite are described in detail below.

+

+<sect2>X Test Suite

+

+          <sect3> Introduction

+            <p>

+              The X Test Suite contains tests that verify Xlib functions

+              operate correctly.  The test suite is designed to run on a

+              single X server; however, since X applications will not be

+              able to tell the difference between the DMX server and a

+              standard X server, the X Test Suite should also run on the

+              DMX server.

+            <p>

+              The Xdmx server was tested with the X Test Suite, and the

+              existing failures are noted in this section.  To put these

+              results in perspective, we first discuss expected X Test

+              failures and how errors in underlying systems can impact

+              Xdmx test results.

+

+          <sect3>Expected Failures for a Single Head

+            <p>

+              A correctly implemented X server with a single screen is

+              expected to fail certain X Test tests.  The following

+              well-known errors occur because of rounding error in the X

+              server code:

+              <verb>

+XDrawArc: Tests 42, 63, 66, 73

+XDrawArcs: Tests 45, 66, 69, 76

+              </verb>

+            <p>

+              The following failures occur because of the high-level X

+              server implementation:

+              <verb>

+XLoadQueryFont: Test 1

+XListFontsWithInfo: Tests 3, 4

+XQueryFont: Tests 1, 2

+              </verb>

+            <p>

+              The following test fails when running the X server as root

+              under Linux because of the way directory modes are

+              interpreted:

+              <verb>

+XWriteBitmapFile: Test 3

+              </verb>

+            <p>

+              Depending on the video card used for the back-end, other

+              failures may also occur because of bugs in the low-level

+              driver implementation.  Over time, failures of this kind

+              are usually fixed by XFree86, but will show up in Xdmx

+              testing until then.

+

+          <sect3>Expected Failures for Xinerama

+            <p>

+              Xinerama fails several X Test Suite tests because of

+              design decisions made for the current implementation of

+              Xinerama.  Over time, many of these errors will be

+              corrected by XFree86 and the group working on a new

+              Xinerama implementation.  Therefore, Xdmx will also share

+              X Suite Test failures with Xinerama.

+            <p>

+              We may be able to fix or work-around some of these

+              failures at the Xdmx level, but this will require

+              additional exploration that was not part of Phase I.

+            <p>

+              Xinerama is constantly improving, and the list of

+              Xinerama-related failures depends on XFree86 version and

+              the underlying graphics hardware.  We tested with a

+              variety of hardware, including nVidia, S3, ATI Radeon,

+              and Matrox G400 (in dual-head mode).  The list below

+              includes only those failures that appear to be from the

+              Xinerama layer, and does not include failures listed in

+              the previous section, or failures that appear to be from

+              the low-level graphics driver itself:

+            <p>

+              These failures were noted with multiple Xinerama

+              configurations:

+              <verb>

+XCopyPlane: Tests 13, 22, 31 (well-known Xinerama implementation issue)

+XSetFontPath: Test 4

+XGetDefault: Test 5

+XMatchVisualInfo: Test 1

+              </verb>

+            <p>

+              These failures were noted only when using one dual-head

+              video card with a 4.2.99.x XFree86 server:

+              <verb>

+XListPixmapFormats: Test 1

+XDrawRectangles: Test 45

+              </verb>

+            <p>

+              These failures were noted only when using two video cards

+              from different vendors with a 4.1.99.x XFree86 server:

+              <verb>

+XChangeWindowAttributes: Test 32

+XCreateWindow: Test 30

+XDrawLine: Test 22

+XFillArc: Test 22

+XChangeKeyboardControl: Tests 9, 10

+XRebindKeysym: Test 1

+              </verb>

+

+          <sect3>Additional Failures from Xdmx

+            <p>

+              When running Xdmx, no unexpected failures were noted.

+              Since the Xdmx server is based on Xinerama, we expect to

+              have most of the Xinerama failures present in the Xdmx

+              server.  Similarly, since the Xdmx server must rely on the

+              low-level device drivers on each back-end server, we also

+              expect that Xdmx will exhibit most of the back-end

+              failures.  Here is a summary:

+              <verb>

+XListPixmapFormats: Test 1 (configuration dependent)

+XChangeWindowAttributes: Test 32

+XCreateWindow: Test 30

+XCopyPlane: Test 13, 22, 31

+XSetFontPath: Test 4

+XGetDefault: Test 5 (configuration dependent)

+XMatchVisualInfo: Test 1

+XRebindKeysym: Test 1 (configuration dependent)

+              </verb>

+            <p>

+              Note that this list is shorter than the combined list for

+              Xinerama because Xdmx uses different code paths to perform

+              some Xinerama operations.  Further, some Xinerama failures

+              have been fixed in the XFree86 4.2.99.x CVS repository.

+            

+          <sect3>Summary and Future Work

+            <p>

+              Running the X Test Suite on Xdmx does not produce any

+              failures that cannot be accounted for by the underlying

+              Xinerama subsystem used by the front-end or by the

+              low-level device-driver code running on the back-end X

+              servers.  The Xdmx server therefore is as ``correct'' as

+              possible with respect to the standard set of X Test Suite

+              tests.

+            <p>

+              During the following phases, we will continue to verify

+              Xdmx correctness using the X Test Suite.  We may also use

+              other tests suites or write additional tests that run

+              under the X Test Suite that specifically verify the

+              expected behavior of DMX.

+

+<sect2>Fonts

+

+<p>In Phase I, fonts are handled directly by both the front-end and the

+back-end servers, which is required since we must treat each back-end

+server during this phase as a ``black box''.  What this requires is that

+<bf/the front- and back-end servers must share the exact same font

+path/.  There are two ways to help make sure that all servers share the

+same font path:

+

+<enum>

+    <item>First, each server can be configured to use the same font

+    server.  The font server, xfs, can be configured to serve fonts to

+    multiple X servers via TCP.

+

+    <item>Second, each server can be configured to use the same font

+    path and either those font paths can be copied to each back-end

+    machine or they can be mounted (e.g., via NFS) on each back-end

+    machine.

+</enum>

+

+<p>One additional concern is that a client program can set its own font

+path, and if it does so, then that font path must be available on each

+back-end machine.

+

+<p>The -fontpath command line option was added to allow users to

+initialize the font path of the front end server.  This font path is

+propagated to each back-end server when the default font is loaded.  If

+there are any problems, an error message is printed, which will describe

+the problem and list the current font path.  For more information about

+setting the font path, see the -fontpath option description in the man

+page.

+

+<sect2>Performance

+

+<p>Phase I of development was not intended to optimize performance.  Its

+focus was on completely and correctly handling the base X11 protocol in

+the Xdmx server.  However, several insights were gained during Phase I,

+which are listed here for reference during the next phase of

+development.

+

+<enum>

+    <item>Calls to XSync() can slow down rendering since it requires a

+    complete round trip to and from a back-end server.  This is

+    especially problematic when communicating over long haul networks.

+    <item>Sending drawing requests to only the screens that they overlap

+    should improve performance.

+</enum>

+

+<sect2>Pixmaps

+

+<p>Pixmaps were originally expected to be handled entirely in the

+front-end X server; however, it was found that this overly complicated

+the rendering code and would have required sending potentially large

+images to each back server that required them when copying from pixmap

+to screen.  Thus, pixmap state is mirrored in the back-end server just

+as it is with regular window state.  With this implementation, the same

+rendering code that draws to windows can be used to draw to pixmaps on

+the back-end server, and no large image transfers are required to copy

+from pixmap to window.

+

+<!-- ============================================================ -->

+<sect1>Phase II

+

+<p>The second phase of development concentrates on performance

+optimizations.  These optimizations are documented here, with

+<tt/x11perf/ data to show how the optimizations improve performance.

+

+<p>All benchmarks were performed by running Xdmx on a dual processor

+1.4GHz AMD Athlon machine with 1GB of RAM connecting over 100baseT to

+two single-processor 1GHz Pentium III machines with 256MB of RAM and ATI

+Rage 128 (RF) video cards.  The front end was running Linux

+2.4.20-pre1-ac1 and the back ends were running Linux 2.4.7-10 and

+version 4.2.99.1 of XFree86 pulled from the XFree86 CVS repository on

+August 7, 2002.  All systems were running Red Hat Linux 7.2.

+

+<sect2>Moving from XFree86 4.1.99.1 to 4.2.0.0

+

+<p>For phase II, the working source tree was moved to the branch tagged

+with dmx-1-0-branch and was updated from version 4.1.99.1 (20 August

+2001) of the XFree86 sources to version 4.2.0.0 (18 January 2002).

+After this update, the following tests were noted to be more than 10%

+faster:

+            <verb>

+1.13   Fill 300x300 opaque stippled trapezoid (161x145 stipple) 

+1.16   Fill 1x1 tiled trapezoid (161x145 tile) 

+1.13   Fill 10x10 tiled trapezoid (161x145 tile) 

+1.17   Fill 100x100 tiled trapezoid (161x145 tile) 

+1.16   Fill 1x1 tiled trapezoid (216x208 tile) 

+1.20   Fill 10x10 tiled trapezoid (216x208 tile) 

+1.15   Fill 100x100 tiled trapezoid (216x208 tile) 

+1.37   Circulate Unmapped window (200 kids) 

+            </verb>

+And the following tests were noted to be more than 10% slower:

+            <verb>

+0.88   Unmap window via parent (25 kids) 

+0.75   Circulate Unmapped window (4 kids) 

+0.79   Circulate Unmapped window (16 kids) 

+0.80   Circulate Unmapped window (25 kids) 

+0.82   Circulate Unmapped window (50 kids) 

+0.85   Circulate Unmapped window (75 kids) 

+            </verb>

+<p>These changes were not caused by any changes in the DMX system, and

+may point to changes in the XFree86 tree or to tests that have more

+"jitter" than most other <tt/x11perf/ tests.

+

+<sect2>Global changes

+

+<p>During the development of the Phase II DMX server, several global

+changes were made.  These changes were also compared with the Phase I

+server.  The following tests were noted to be more than 10% faster:

+            <verb>

+1.13   Fill 300x300 opaque stippled trapezoid (161x145 stipple) 

+1.15   Fill 1x1 tiled trapezoid (161x145 tile) 

+1.13   Fill 10x10 tiled trapezoid (161x145 tile) 

+1.17   Fill 100x100 tiled trapezoid (161x145 tile) 

+1.16   Fill 1x1 tiled trapezoid (216x208 tile) 

+1.19   Fill 10x10 tiled trapezoid (216x208 tile) 

+1.15   Fill 100x100 tiled trapezoid (216x208 tile) 

+1.15   Circulate Unmapped window (4 kids) 

+            </verb>

+

+<p>The following tests were noted to be more than 10% slower:

+            <verb>

+0.69   Scroll 10x10 pixels 

+0.68   Scroll 100x100 pixels 

+0.68   Copy 10x10 from window to window 

+0.68   Copy 100x100 from window to window 

+0.76   Circulate Unmapped window (75 kids) 

+0.83   Circulate Unmapped window (100 kids) 

+            </verb>

+

+<p>For the remainder of this analysis, the baseline of comparison will

+be the Phase II deliverable with all optimizations disabled (unless

+otherwise noted).  This will highlight how the optimizations in

+isolation impact performance.

+

+<sect2>XSync() Batching

+

+<p>During the Phase I implementation, XSync() was called after every

+protocol request made by the DMX server.  This provided the DMX server

+with an interactive feel, but defeated X11's protocol buffering system

+and introduced round-trip wire latency into every operation.  During

+Phase II, DMX was changed so that protocol requests are no longer

+followed by calls to XSync().  Instead, the need for an XSync() is

+noted, and XSync() calls are only made every 100mS or when the DMX

+server specifically needs to make a call to guarantee interactivity.

+With this new system, X11 buffers protocol as much as possible during a

+100mS interval, and many unnecessary XSync() calls are avoided.

+

+<p>Out of more than 300 <tt/x11perf/ tests, 8 tests became more than 100

+times faster, with 68 more than 50X faster, 114 more than 10X faster,

+and 181 more than 2X faster.  See table below for summary.

+

+<p>The following tests were noted to be more than 10% slower with

+XSync() batching on:

+            <verb>

+0.88   500x500 tiled rectangle (161x145 tile) 

+0.89   Copy 500x500 from window to window 

+            </verb>

+

+<sect2>Offscreen Optimization

+

+<p>Windows span one or more of the back-end servers' screens; however,

+during Phase I development, windows were created on every back-end

+server and every rendering request was sent to every window regardless

+of whether or not that window was visible.  With the offscreen

+optimization, the DMX server tracks when a window is completely off of a

+back-end server's screen and, in that case, it does not send rendering

+requests to those back-end windows.  This optimization saves bandwidth

+between the front and back-end servers, and it reduces the number of

+XSync() calls.  The performance tests were run on a DMX system with only

+two back-end servers.  Greater performance gains will be had as the

+number of back-end servers increases.

+

+<p>Out of more than 300 <tt/x11perf/ tests, 3 tests were at least twice as

+fast, and 146 tests were at least 10% faster.  Two tests were more than

+10% slower with the offscreen optimization:

+            <verb>

+0.88   Hide/expose window via popup (4 kids) 

+0.89   Resize unmapped window (75 kids) 

+            </verb>

+

+<sect2>Lazy Window Creation Optimization

+

+<p>As mentioned above, during Phase I, windows were created on every

+back-end server even if they were not visible on that back-end.  With

+the lazy window creation optimization, the DMX server does not create

+windows on a back-end server until they are either visible or they

+become the parents of a visible window.  This optimization builds on the

+offscreen optimization (described above) and requires it to be enabled.

+

+<p>The lazy window creation optimization works by creating the window

+data structures in the front-end server when a client creates a window,

+but delays creation of the window on the back-end server(s).  A private

+window structure in the DMX server saves the relevant window data and

+tracks changes to the window's attributes and stacking order for later

+use.  The only times a window is created on a back-end server are (1)

+when it is mapped and is at least partially overlapping the back-end

+server's screen (tracked by the offscreen optimization), or (2) when the

+window becomes the parent of a previously visible window.  The first

+case occurs when a window is mapped or when a visible window is copied,

+moved or resized and now overlaps the back-end server's screen.  The

+second case occurs when starting a window manager after having created

+windows to which the window manager needs to add decorations.

+

+<p>When either case occurs, a window on the back-end server is created

+using the data saved in the DMX server's window private data structure.

+The stacking order is then adjusted to correctly place the window on the

+back-end and lastly the window is mapped.  From this time forward, the

+window is handled exactly as if the window had been created at the time

+of the client's request.

+

+<p>Note that when a window is no longer visible on a back-end server's

+screen (e.g., it is moved offscreen), the window is not destroyed;

+rather, it is kept and reused later if the window once again becomes

+visible on the back-end server's screen.  Originally with this

+optimization, destroying windows was implemented but was later rejected

+because it increased bandwidth when windows were opaquely moved or

+resized, which is common in many window managers.

+

+<p>The performance tests were run on a DMX system with only two back-end

+servers.  Greater performance gains will be had as the number of

+back-end servers increases.

+

+<p>This optimization improved the following <tt/x11perf/ tests by more

+than 10%:

+            <verb>

+1.10   500x500 rectangle outline 

+1.12   Fill 100x100 stippled trapezoid (161x145 stipple) 

+1.20   Circulate Unmapped window (50 kids) 

+1.19   Circulate Unmapped window (75 kids) 

+            </verb>

+            

+<sect2>Subdividing Rendering Primitives

+

+<p>X11 imaging requests transfer significant data between the client and

+the X server.  During Phase I, the DMX server would then transfer the

+image data to each back-end server.  Even with the offscreen

+optimization (above), these requests still required transferring

+significant data to each back-end server that contained a visible

+portion of the window.  For example, if the client uses XPutImage() to

+copy an image to a window that overlaps the entire DMX screen, then the

+entire image is copied by the DMX server to every back-end server.

+

+<p>To reduce the amount of data transferred between the DMX server and

+the back-end servers when XPutImage() is called, the image data is

+subdivided and only the data that will be visible on a back-end server's

+screen is sent to that back-end server.  Xinerama already implements a

+subdivision algorithm for XGetImage() and no further optimization was

+needed.

+

+<p>Other rendering primitives were analyzed, but the time required to

+subdivide these primitives was a significant proportion of the time

+required to send the entire rendering request to the back-end server, so

+this optimization was rejected for the other rendering primitives.

+

+<p>Again, the performance tests were run on a DMX system with only two

+back-end servers.  Greater performance gains will be had as the number

+of back-end servers increases.

+

+<p>This optimization improved the following <tt/x11perf/ tests by more

+than 10%:

+            <verb>

+1.12   Fill 100x100 stippled trapezoid (161x145 stipple)

+1.45   Circulate Unmapped window (75 kids) 

+1.74   Circulate Unmapped window (100 kids) 

+            </verb>

+

+<p>The following test was noted to be more than 10% slower with this

+optimization:

+            <verb>

+0.88   10-pixel fill chord partial circle 

+            </verb>

+

+<sect2>Summary of x11perf Data

+

+<p>With all of the optimizations on, 53 <tt/x11perf/ tests are more than

+100X faster than the unoptimized Phase II deliverable, with 69 more than

+50X faster, 73 more than 10X faster, and 199 more than twice as fast.

+No tests were more than 10% slower than the unoptimized Phase II

+deliverable.  (Compared with the Phase I deliverable, only Circulate

+Unmapped window (100 kids) was more than 10% slower than the Phase II

+deliverable.  As noted above, this test seems to have wider variability

+than other <tt/x11perf/ tests.)

+

+<p>The following table summarizes relative <tt/x11perf/ test changes for

+all optimizations individually and collectively.  Note that some of the

+optimizations have a synergistic effect when used together.

+<sect2>Profiling with OProfile

+

+<p>OProfile (available from http://oprofile.sourceforge.net/) is a

+system-wide profiler for Linux systems that uses processor-level

+counters to collect sampling data.  OProfile can provide information

+that is similar to that provided by <tt/gprof/, but without the

+necessity of recompiling the program with special instrumentation (i.e.,

+OProfile can collect statistical profiling information about optimized

+programs).  A test harness was developed to collect OProfile data for

+each <tt/x11perf/ test individually.

+

+<p>Test runs were performed using the RETIRED_INSNS counter on the AMD

+Athlon and the CPU_CLK_HALTED counter on the Intel Pentium III (with a

+test configuration different from the one described above).  We have

+examined OProfile output and have compared it with <tt/gprof/ output.

+This investigation has not produced results that yield performance

+increases in <tt/x11perf/ numbers.

+

+<!--

+<sect3>Retired Instructions

+

+<p>The initial tests using OProfile were done using the RETIRED_INSNS

+counter with DMX running on the dual-processor AMD Athlon machine - the

+same test configuration that was described above and that was used for

+other tests.  The RETIRED_INSNS counter counts retired instructions and

+showed drawing, text, copying, and image tests to be dominated (&gt;

+30%) by calls to Hash(), SecurityLookupIDByClass(),

+SecurityLookupIDByType(), and StandardReadRequestFromClient().  Some of

+these tests also executed significant instructions in

+WaitForSomething().

+

+<p>In contrast, the window tests executed significant

+instructions in SecurityLookupIDByType(), Hash(),

+StandardReadRequestFromClient(), but also executed significant

+instructions in other routines, such as ConfigureWindow().  Some time

+was spent looking at Hash() function, but optimizations in this routine

+did not lead to a dramatic increase in <tt/x11perf/ performance.

+-->

+

+<!-- 

+<sect3>Clock Cycles

+

+<p>Retired instructions can be misleading because Intel/AMD instructions

+execute in variable amounts of time.  The OProfile tests were repeated

+using the Intel CPU_CLK_HALTED counter with DMX running on the second

+back-end machine.  Note that this is a different test configuration that

+the one described above.  However, these tests show the amount of time

+(as measured in CPU cycles) that are spent in each routine.  Because

+<tt/x11perf/ was running on the first back-end machine and because

+window optimizations were on, the load on the second back-end machine

+was not significant.

+

+<p>Using CPU_CLK_HALTED, DMX showed simple drawing

+tests spending more than 10% of their time in

+StandardReadRequestFromClient(), with significant time (&gt; 20% total)

+spent in SecurityLookupIDByClass(), WaitForSomething(), and Dispatch().

+For these tests, &lt; 5% of the time was spent in Hash(), which explains

+why optimizing the Hash() routine did not impact <tt/x11perf/ results.

+

+<p>The trapezoid, text, scrolling, copying, and image tests were

+dominated by time in ProcFillPoly(), PanoramiXFillPoly(), dmxFillPolygon(),

+SecurityLookupIDByClass(), SecurityLookupIDByType(), and

+StandardReadRequestFromClient().  Hash() time was generally above 5% but

+less than 10% of total time.

+-->

+

+<sect2>X Test Suite

+

+<p>The X Test Suite was run on the fully optimized DMX server using the

+configuration described above.  The following failures were noted:

+            <verb>

+XListPixmapFormats: Test 1              [1]

+<!-- ============================================================ -->

+<sect1>Phase III

+

+<p>During the third phase of development, support was provided for the

+following extensions: SHAPE, RENDER, XKEYBOARD, XInput.

+

+<sect2>SHAPE

+

+<p>The SHAPE extension is supported.  Test applications (e.g., xeyes and

+oclock) and window managers that make use of the SHAPE extension will

+work as expected.

+

+<sect2>RENDER

+

+<p>The RENDER extension is supported.  The version included in the DMX

+CVS tree is version 0.2, and this version is fully supported by Xdmx.

+Applications using only version 0.2 functions will work correctly;

+however, some apps that make use of functions from later versions do not

+properly check the extension's major/minor version numbers.  These apps

+will fail with a Bad Implementation error when using post-version 0.2

+functions.  This is expected behavior.  When the DMX CVS tree is updated

+to include newer versions of RENDER, support for these newer functions

+will be added to the DMX X server.

+

+<sect2>XKEYBOARD

+

+<p>The XKEYBOARD extension is supported.  If present on the back-end X

+servers, the XKEYBOARD extension will be used to obtain information

+about the type of the keyboard for initialization.  Otherwise, the

+keyboard will be initialized using defaults.  Note that this departs

+from older behavior: when Xdmx is compiled without XKEYBOARD support,

+the map from the back-end X server will be preserved.  With XKEYBOARD

+support, the map is not preserved because better information and control

+of the keyboard is available.

+

+<sect2>XInput

+

+<p>The XInput extension is supported.  Any device can be used as a core

+device and be used as an XInput extension device, with the exception of

+core devices on the back-end servers.  This limitation is present

+because cursor handling on the back-end requires that the back-end

+cursor sometimes track the Xdmx core cursor -- behavior that is

+incompatible with using the back-end pointer as a non-core device.

+

+<p>Currently, back-end extension devices are not available as Xdmx

+extension devices, but this limitation should be removed in the future.

+

+<p>To demonstrate the XInput extension, and to provide more examples for

+low-level input device driver writers, USB device drivers have been

+written for mice (usb-mou), keyboards (usb-kbd), and

+non-mouse/non-keyboard USB devices (usb-oth).  Please see the man page

+for information on Linux kernel drivers that are required for using

+these Xdmx drivers.

+

+<sect2>DPMS

+

+<p>The DPMS extension is exported but does not do anything at this time.

+

+<sect2>Other Extensions

+

+<p>The LBX,

+       SECURITY,

+       XC-APPGROUP, and

+       XFree86-Bigfont

+extensions do not require any special Xdmx support and have been exported.

+extensions are <it/not/ supported at this time, but will be evaluated

+

+<sect1>Phase IV

+

+<sect2>Moving to XFree86 4.3.0

+

+<p>For Phase IV, the recent release of XFree86 4.3.0 (27 February 2003)

+was merged onto the dmx.sourceforge.net CVS trunk and all work is

+proceeding using this tree.

+

+<sect2>Extensions 

+

+<sect3>XC-MISC (supported)

+

+<p>XC-MISC is used internally by the X library to recycle XIDs from the

+X server.  This is important for long-running X server sessions.  Xdmx

+supports this extension.  The X Test Suite passed and failed the exact

+same tests before and after this extension was enabled.

+<!-- Tested February/March 2003 -->

+

+<sect3>Extended-Visual-Information (supported)

+

+<p>The Extended-Visual-Information extension provides a method for an X

+client to obtain detailed visual information.  Xdmx supports this

+extension.  It was tested using the <tt>hw/dmx/examples/evi</tt> example

+program.  <bf/Note that this extension is not Xinerama-aware/ -- it will

+return visual information for each screen even though Xinerama is

+causing the X server to export a single logical screen.

+<!-- Tested March 2003 -->

+

+<sect3>RES (supported)

+

+<p>The X-Resource extension provides a mechanism for a client to obtain

+detailed information about the resources used by other clients.  This

+extension was tested with the <tt>hw/dmx/examples/res</tt> program.  The

+X Test Suite passed and failed the exact same tests before and after

+this extension was enabled.

+<!-- Tested March 2003 -->

+

+<sect3>BIG-REQUESTS (supported)

+

+<p>This extension enables the X11 protocol to handle requests longer

+than 262140 bytes.  The X Test Suite passed and failed the exact same

+tests before and after this extension was enabled.

+<!-- Tested March 2003 -->

+

+<sect3>XSYNC (supported)

+

+<p>This extension provides facilities for two different X clients to

+synchronize their requests.  This extension was minimally tested with

+<tt/xdpyinfo/ and the X Test Suite passed and failed the exact same

+tests before and after this extension was enabled.

+<!-- Tested March 2003 -->

+

+<sect3>XTEST, RECORD, DEC-XTRAP (supported) and XTestExtension1 (not supported)

+

+<p>The XTEST and RECORD extension were developed by the X Consortium for

+use in the X Test Suite and are supported as a standard in the X11R6

+tree.  They are also supported in Xdmx.  When X Test Suite tests that

+make use of the XTEST extension are run, Xdmx passes and fails exactly

+the same tests as does a standard XFree86 X server.  When the

+<tt/rcrdtest/ test (a part of the X Test Suite that verifies the RECORD

+extension) is run, Xdmx passes and fails exactly the same tests as does

+a standard XFree86 X server. <!-- Tested February/March 2003 -->

+

+<p>There are two older XTEST-like extensions: DEC-XTRAP and

+XTestExtension1.  The XTestExtension1 extension was developed for use by

+the X Testing Consortium for use with a test suite that eventually

+became (part of?) the X Test Suite.  Unlike XTEST, which only allows

+events to be sent to the server, the XTestExtension1 extension also

+allowed events to be recorded (similar to the RECORD extension).  The

+second is the DEC-XTRAP extension that was developed by the Digital

+Equipment Corporation.

+

+<p>The DEC-XTRAP extension is available from Xdmx and has been tested

+with the <tt/xtrap*/ tools which are distributed as standard X11R6

+clients. <!-- Tested March 2003 -->

+

+<p>The XTestExtension1 is <em/not/ supported because it does not appear

+to be used by any modern X clients (the few that support it also support

+XTEST) and because there are no good methods available for testing that

+it functions correctly (unlike XTEST and DEC-XTRAP, the code for

+XTestExtension1 is not part of the standard X server source tree, so

+additional testing is important). <!-- Tested March 2003 -->

+

+<p>Most of these extensions are documented in the X11R6 source tree.

+locate -- for completeness and historical interest, citations are

+Proposal. Hewlett Packard, November 1991.

+</descrip>

+

+<sect3>MIT-MISC (not supported)

+

+<p>The MIT-MISC extension is used to control a bug-compatibility flag

+that provides compatibility with xterm programs from X11R1 and X11R2.

+There does not appear to be a single client available that makes use of

+this extension and there is not way to verify that it works correctly.

+The Xdmx server does <em/not/ support MIT-MISC.

+

+<sect3>SCREENSAVER (not supported)

+

+<p>This extension provides special support for the X screen saver.  It

+was tested with beforelight, which appears to be the only client that

+works with it.  When Xinerama was not active, <tt/beforelight/ behaved

+as expected.  However, when Xinerama was active, <tt/beforelight/ did

+not behave as expected.  Further, when this extension is not active,

+<tt/xscreensaver/ (a widely-used X screen saver program) did not behave

+as expected.  Since this extension is not Xinerama-aware and is not

+commonly used with expected results by clients, we have left this

+extension disabled at this time.

+

+<sect3>GLX (supported)

+

+<p>The GLX extension provides OpenGL and GLX windowing support.  In

+Xdmx, the extension is called glxProxy, and it is Xinerama aware.  It

+works by either feeding requests forward through Xdmx to each of the

+back-end servers or handling them locally.  All rendering requests are

+handled on the back-end X servers.  This code was donated to the DMX

+project by SGI.  For the X Test Suite results comparison, see below.

+

+<sect3>RENDER (supported)

+

+<p>The X Rendering Extension (RENDER) provides support for digital image

+composition.  Geometric and text rendering are supported.  RENDER is

+partially Xinerama-aware, with text and the most basic compositing

+operator; however, its higher level primitives (triangles, triangle

+strips, and triangle fans) are not yet Xinerama-aware.  The RENDER

+extension is still under development, and is currently at version 0.8.

+Additional support will be required in DMX as more primitives and/or

+requests are added to the extension.

+

+<p>There is currently no test suite for the X Rendering Extension;

+however, there has been discussion of developing a test suite as the

+extension matures.  When that test suite becomes available, additional

+testing can be performed with Xdmx.  The X Test Suite passed and failed

+the exact same tests before and after this extension was enabled.

+

+

+<sect2>Additional Testing with the X Test Suite

+

+<sect3>XFree86 without XTEST

+

+<p>After the release of XFree86 4.3.0, we retested the XFree86 X server

+with and without using the XTEST extension.  When the XTEST extension

+was <em/not/ used for testing, the XFree86 4.3.0 server running on our

+usual test system with a Radeon VE card reported unexpected failures in

+the following tests:

+<verb>

+XListPixmapFormats: Test 1

+XChangeKeyboardControl: Tests 9, 10

+XGetDefault: Test 5

+XRebindKeysym: Test 1

+</verb>

+

+<sect3>XFree86 with XTEST

+

+<p>When using the XTEST extension, the XFree86 4.3.0 server reported the

+following errors:

+<verb>

+XListPixmapFormats: Test 1

+XChangeKeyboardControl: Tests 9, 10

+XGetDefault: Test 5

+XRebindKeysym: Test 1

+

+XAllowEvents: Tests 20, 21, 24

+XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25

+XGrabKey: Test 8

+XSetPointerMapping: Test 3

+XUngrabButton: Test 4

+</verb>

+

+<p>While these errors may be important, they will probably be fixed

+eventually in the XFree86 source tree.  We are particularly interested

+in demonstrating that the Xdmx server does not introduce additional

+failures that are not known Xinerama failures.

+

+<sect3>Xdmx with XTEST, without Xinerama, without GLX

+

+<p>Without Xinerama, but using the XTEST extension, the following errors

+were reported from Xdmx (note that these are the same as for the XFree86

+4.3.0, except that XGetDefault no longer fails):

+<verb>

+XListPixmapFormats: Test 1

+XChangeKeyboardControl: Tests 9, 10

+XRebindKeysym: Test 1

+

+XAllowEvents: Tests  20, 21, 24

+XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25

+XGrabKey: Test 8

+XSetPointerMapping: Test 3

+XUngrabButton: Test 4

+</verb>

+

+<sect3>Xdmx with XTEST, with Xinerama, without GLX

+

+<p>With Xinerama, using the XTEST extension, the following errors

+were reported from Xdmx:

+<verb>

+XListPixmapFormats: Test 1

+XChangeKeyboardControl: Tests 9, 10

+XRebindKeysym: Test 1

+

+XAllowEvents: Tests 20, 21, 24

+XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25

+XGrabKey: Test 8

+XSetPointerMapping: Test 3

+XUngrabButton: Test 4

+

+XCopyPlane: Tests 13, 22, 31 (well-known XTEST/Xinerama interaction issue)

+XDrawLine: Test 67

+XDrawLines: Test 91

+XDrawSegments: Test 68

+</verb>

+Note that the first two sets of errors are the same as for the XFree86

+4.3.0 server, and that the XCopyPlane error is a well-known error

+resulting from an XTEST/Xinerama interaction when the request crosses a

+screen boundary.  The XDraw* errors are resolved when the tests are run

+individually and they do not cross a screen boundary.  We will

+investigate these errors further to determine their cause.

+

+<sect3>Xdmx with XTEST, with Xinerama, with GLX

+

+<p>With GLX enabled, using the XTEST extension, the following errors

+were reported from Xdmx (these results are from early during the Phase

+IV development, but were confirmed with a late Phase IV snapshot):

+<verb>

+XListPixmapFormats: Test 1

+XChangeKeyboardControl: Tests 9, 10

+XRebindKeysym: Test 1

+

+XAllowEvents: Tests 20, 21, 24

+XGrabButton: Tests 5, 9-12, 14, 16, 19, 21-25

+XGrabKey: Test 8

+XSetPointerMapping: Test 3

+XUngrabButton: Test 4

+

+XClearArea: Test 8

+XCopyArea: Tests 4, 5, 11, 14, 17, 23, 25, 27, 30

+XCopyPlane: Tests 6, 7, 10, 19, 22, 31

+XDrawArcs: Tests 89, 100, 102

+XDrawLine: Test 67

+XDrawSegments: Test 68

+</verb>

+Note that the first two sets of errors are the same as for the XFree86

+4.3.0 server, and that the third set has different failures than when

+Xdmx does not include GLX support.  Since the GLX extension adds new

+visuals to support GLX's visual configs and the X Test Suite runs tests

+over the entire set of visuals, additional rendering tests were run and

+presumably more of them crossed a screen boundary.  This conclusion is

+supported by the fact that nearly all of the rendering errors reported

+are resolved when the tests are run individually and they do no cross a

+screen boundary.

+

+<p>Further, when hardware rendering is disabled on the back-end displays,

+many of the errors in the third set are eliminated, leaving only:

+<verb>

+XClearArea: Test 8

+XCopyArea: Test 4, 5, 11, 14, 17, 23, 25, 27, 30

+XCopyPlane: Test 6, 7, 10, 19, 22, 31

+</verb>

+

+<sect3>Conclusion

+

+<p>We conclude that all of the X Test Suite errors reported for Xdmx are

+the result of errors in the back-end X server or the Xinerama

+implementation.  Further, all of these errors that can be reasonably

+fixed at the Xdmx layer have been.  (Where appropriate, we have

+submitted patches to the XFree86 and Xinerama upstream maintainers.)

+

+<sect2>Dynamic Reconfiguration

+

+<p>During this development phase, dynamic reconfiguration support was

+added to DMX.  This support allows an application to change the position

+and offset of a back-end server's screen.  For example, if the

+application would like to shift a screen slightly to the left, it could

+query Xdmx for the screen's &lt;x,y&gt; position and then dynamically

+reconfigure that screen to be at position &lt;x+10,y&gt;.  When a screen

+is dynamically reconfigured, input handling and a screen's root window

+dimensions are adjusted as needed.  These adjustments are transparent to

+the user.

+

+<sect3>Dynamic reconfiguration extension

+

+<p>The application interface to DMX's dynamic reconfiguration is through

+a function in the DMX extension library:

+<verb>

+Bool DMXReconfigureScreen(Display *dpy, int screen, int x, int y)

+</verb>

+where <it/dpy/ is DMX server's display, <it/screen/ is the number of the

+screen to be reconfigured, and <it/x/ and <it/y/ are the new upper,

+left-hand coordinates of the screen to be reconfigured.

+

+<p>The coordinates are not limited other than as required by the X

+protocol, which limits all coordinates to a signed 16 bit number.  In

+addition, all coordinates within a screen must also be legal values.

+Therefore, setting a screen's upper, left-hand coordinates such that the

+right or bottom edges of the screen is greater than 32,767 is illegal.

+

+<sect3>Bounding box

+

+<p>When the Xdmx server is started, a bounding box is calculated from

+the screens' layout given either on the command line or in the

+configuration file.  This bounding box is currently fixed for the

+lifetime of the Xdmx server.

+

+<p>While it is possible to move a screen outside of the bounding box, it

+is currently not possible to change the dimensions of the bounding box.

+For example, it is possible to specify coordinates of &lt;-100,-100&gt;

+for the upper, left-hand corner of the bounding box, which was

+previously at coordinates &lt;0,0&gt;.  As expected, the screen is moved

+down and to the right; however, since the bounding box is fixed, the

+left side and upper portions of the screen exposed by the

+reconfiguration are no longer accessible on that screen.  Those

+inaccessible regions are filled with black.

+

+<p>This fixed bounding box limitation will be addressed in a future

+development phase.

+

+<sect3>Sample applications

+

+<p>An example of where this extension is useful is in setting up a video

+wall.  It is not always possible to get everything perfectly aligned,

+and sometimes the positions are changed (e.g., someone might bump into a

+projector).  Instead of physically moving projectors or monitors, it is

+now possible to adjust the positions of the back-end server's screens

+using the dynamic reconfiguration support in DMX.

+

+<p>Other applications, such as automatic setup and calibration tools,

+can make use of dynamic reconfiguration to correct for projector

+alignment problems, as long as the projectors are still arranged

+rectilinearly.  Horizontal and vertical keystone correction could be

+applied to projectors to correct for non-rectilinear alignment problems;

+however, this must be done external to Xdmx.

+

+<p>A sample test program is included in the DMX server's examples

+directory to demonstrate the interface and how an application might use

+dynamic reconfiguration.  See <tt/dmxreconfig.c/ for details.

+

+<sect3>Additional notes

+

+<p>In the original development plan, Phase IV was primarily devoted to

+adding OpenGL support to DMX; however, SGI became interested in the DMX

+project and developed code to support OpenGL/GLX.  This code was later

+donated to the DMX project and integrated into the DMX code base, which

+freed the DMX developers to concentrate on dynamic reconfiguration (as

+described above).

+

+<sect2>Doxygen documentation

+

+<p>Doxygen is an open-source (GPL) documentation system for generating

+browseable documentation from stylized comments in the source code.  We

+have placed all of the Xdmx server and DMX protocol source code files

+under Doxygen so that comprehensive documentation for the Xdmx source

+code is available in an easily browseable format.

+

+<sect2>Valgrind

+

+<p>Valgrind, an open-source (GPL) memory debugger for Linux, was used to

+search for memory management errors.  Several memory leaks were detected

+and repaired.  The following errors were not addressed:

+<enum>

+    <item>

+        When the X11 transport layer sends a reply to the client, only

+        those fields that are required by the protocol are filled in --

+        unused fields are left as uninitialized memory and are therefore

+        noted by valgrind.  These instances are not errors and were not

+        repaired.

+    <item>

+        At each server generation, glxInitVisuals allocates memory that

+        is never freed.  The amount of memory lost each generation

+        approximately equal to 128 bytes for each back-end visual.

+        Because the code involved is automatically generated, this bug

+        has not been fixed and will be referred to SGI.

+    <item>

+        At each server generation, dmxRealizeFont calls XLoadQueryFont,

+        which allocates a font structure that is not freed.

+        dmxUnrealizeFont can free the font structure for the first

+        screen, but cannot free it for the other screens since they are

+        already closed by the time dmxUnrealizeFont could free them.

+        The amount of memory lost each generation is approximately equal

+        to 80 bytes per font per back-end.  When this bug is fixed in

+        the the X server's device-independent (dix) code, DMX will be

+        able to properly free the memory allocated by XLoadQueryFont.

+</enum>

+

+<sect2>RATS

+

+<p>RATS (Rough Auditing Tool for Security) is an open-source (GPL)

+security analysis tool that scans source code for common

+security-related programming errors (e.g., buffer overflows and TOCTOU

+races).  RATS was used to audit all of the code in the hw/dmx directory

+and all "High" notations were checked manually.  The code was either

+re-written to eliminate the warning, or a comment containing "RATS" was

+inserted on the line to indicate that a human had checked the code.

+Unrepaired warnings are as follows:

+<enum>

+    <item>

+        Fixed-size buffers are used in many areas, but code has been

+        added to protect against buffer overflows (e.g., XmuSnprint).

+        The only instances that have not yet been fixed are in

+        config/xdmxconfig.c (which is not part of the Xdmx server) and

+        input/usb-common.c.

+    <item>

+        vprintf and vfprintf are used in the logging routines.  In

+        general, all uses of these functions (e.g., dmxLog) provide a

+        constant format string from a trusted source, so the use is

+        relatively benign.

+    <item>

+        glxProxy/glxscreens.c uses getenv and strcat.  The use of these

+        functions is safe and will remain safe as long as

+        ExtensionsString is longer then GLXServerExtensions (ensuring

+        this may not be ovious to the casual programmer, but this is in

+        automatically generated code, so we hope that the generator

+        enforces this constraint).

-     * such a thing as a VGA "standard"...  And, thank the Creator for the fact
-     * that Hilbert spaces are not yet implemented in this industry.
-     *
-     * The following implements a trick suggested by David Dawes.  This sets
-     * [HV]BlankEnd to zero if the blanking interval does not already contain a
-     * 0-point, and decrements it by one otherwise.  In the latter case, this
-     * will produce a left and/or top overscan which the colourmap code will
-     * (still) need to ensure is as close to black as possible.  This will make
-     * the behaviour consistent across all chipsets, while allowing all
-     * chipsets to display the entire screen.  Non-KGA drivers can ignore the
-     * following in their own copy of this code.

+     * means only part of the screen shows.  This affects how null overscans

+     * are to be implemented on such adapters.

+     *

+     * Henceforth, VGA cores that implement this broken, but unfortunately

+     * common, behaviour are to be designated as KGA's, in honour of Koen

+     * Gadeyne, whose zeal to eliminate overscans (read: fury) set in motion

+     * a series of events that led to the discovery of this problem.

+     *

+     * Some VGA's are KGA's only in the horizontal, or only in the vertical,

+     * some in both, others in neither.  Don't let anyone tell you there is

+     * such a thing as a VGA "standard"...  And, thank the Creator for the fact

+     * that Hilbert spaces are not yet implemented in this industry.

+     *

+     * The following implements a trick suggested by David Dawes.  This sets

+     * [HV]BlankEnd to zero if the blanking interval does not already contain a

+     * 0-point, and decrements it by one otherwise.  In the latter case, this

+     * will produce a left and/or top overscan which the colourmap code will

+     * (still) need to ensure is as close to black as possible.  This will make

+     * the behaviour consistent across all chipsets, while allowing all

+     * chipsets to display the entire screen.  Non-KGA drivers can ignore the

+     * following in their own copy of this code.

-
-   In this file we have GC level replacements for PolyText8/16,
-   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for NonTE (proportional) 
-   fonts. The idea is that everything in this file is device independent.
-   The mentioned GCOps are merely wrappers for the 
-   PolyGlyphBltNonTEColorExpansion and ImageGlyphBltNonTEColorExpansion
-   functions which calculate the boxes containing arbitrarily clipped 
-   text and passes them to the NonTEGlyphRenderer which will usually 
-   be a lower level XAA function which renders these clipped glyphs using
-   the basic color expansion functions exported by the chipset driver.
-   The NonTEGlyphRenderer itself may optionally be driver supplied to
-   facilitate work-arounds/optimizations at a higher level than usual.

+

+   In this file we have GC level replacements for PolyText8/16,

+   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for NonTE (proportional) 

+   fonts. The idea is that everything in this file is device independent.

+   The mentioned GCOps are merely wrappers for the 

+   PolyGlyphBltNonTEColorExpansion and ImageGlyphBltNonTEColorExpansion

+   functions which calculate the boxes containing arbitrarily clipped 

+   text and passes them to the NonTEGlyphRenderer which will usually 

+   be a lower level XAA function which renders these clipped glyphs using

+   the basic color expansion functions exported by the chipset driver.

+   The NonTEGlyphRenderer itself may optionally be driver supplied to

+   facilitate work-arounds/optimizations at a higher level than usual.

+ *	The algorithm is to order the edges from smallest

+ *	y to largest by partitioning the array into a left

+ *	edge list and a right edge list.  The algorithm used

+ *	to traverse each edge is digital differencing analyzer

+ *	line algorithm with y as the major axis. There's some funny linear

- * The functions in this file implement the Region abstraction used extensively
- * throughout the X11 sample server. A Region is simply a set of disjoint
- * (non-overlapping) rectangles, plus an "extent" rectangle which is the
- * smallest single rectangle that contains all the non-overlapping rectangles.
- *
- * A Region is implemented as a "y-x-banded" array of rectangles.  This array
- * imposes two degrees of order.  First, all rectangles are sorted by top side
- * y coordinate first (y1), and then by left side x coordinate (x1).
- *
- * Furthermore, the rectangles are grouped into "bands".  Each rectangle in a
- * band has the same top y coordinate (y1), and each has the same bottom y
- * coordinate (y2).  Thus all rectangles in a band differ only in their left
- * and right side (x1 and x2).  Bands are implicit in the array of rectangles:
- * there is no separate list of band start pointers.
- *
- * The y-x band representation does not minimize rectangles.  In particular,
- * if a rectangle vertically crosses a band (the rectangle has scanlines in 
- * the y1 to y2 area spanned by the band), then the rectangle may be broken
- * down into two or more smaller rectangles stacked one atop the other. 
- *
- *  -----------				    -----------
- *  |         |				    |         |		    band 0
- *  |         |  --------		    -----------  --------
- *  |         |  |      |  in y-x banded    |         |  |      |   band 1
- *  |         |  |      |  form is	    |         |  |      |
- *  -----------  |      |		    -----------  --------
- *               |      |				 |      |   band 2
- *               --------				 --------
- *
- * An added constraint on the rectangles is that they must cover as much
- * horizontal area as possible: no two rectangles within a band are allowed
- * to touch.
- *
- * Whenever possible, bands will be merged together to cover a greater vertical
- * distance (and thus reduce the number of rectangles). Two bands can be merged
- * only if the bottom of one touches the top of the other and they have
- * rectangles in the same places (of the same width, of course).
- *
- * Adam de Boor wrote most of the original region code.  Joel McCormack
- * substantially modified or rewrote most of the core arithmetic routines,
- * and added miRegionValidate in order to support several speed improvements
- * to miValidateTree.  Bob Scheifler changed the representation to be more
- * compact when empty or a single rectangle, and did a bunch of gratuitous
- * reformatting.

+ * The functions in this file implement the Region abstraction used extensively

+ * throughout the X11 sample server. A Region is simply a set of disjoint

+ * (non-overlapping) rectangles, plus an "extent" rectangle which is the

+ * smallest single rectangle that contains all the non-overlapping rectangles.

+ *

+ * A Region is implemented as a "y-x-banded" array of rectangles.  This array

+ * imposes two degrees of order.  First, all rectangles are sorted by top side

+ * y coordinate first (y1), and then by left side x coordinate (x1).

+ *

+ * Furthermore, the rectangles are grouped into "bands".  Each rectangle in a

+ * band has the same top y coordinate (y1), and each has the same bottom y

+ * coordinate (y2).  Thus all rectangles in a band differ only in their left

+ * and right side (x1 and x2).  Bands are implicit in the array of rectangles:

+ * there is no separate list of band start pointers.

+ *

+ * The y-x band representation does not minimize rectangles.  In particular,

+ * if a rectangle vertically crosses a band (the rectangle has scanlines in 

+ * the y1 to y2 area spanned by the band), then the rectangle may be broken

+ * down into two or more smaller rectangles stacked one atop the other. 

+ *

+ *  -----------				    -----------

+ *  |         |				    |         |		    band 0

+ *  |         |  --------		    -----------  --------

+ *  |         |  |      |  in y-x banded    |         |  |      |   band 1

+ *  |         |  |      |  form is	    |         |  |      |

+ *  -----------  |      |		    -----------  --------

+ *               |      |				 |      |   band 2

+ *               --------				 --------

+ *

+ * An added constraint on the rectangles is that they must cover as much

+ * horizontal area as possible: no two rectangles within a band are allowed

+ * to touch.

+ *

+ * Whenever possible, bands will be merged together to cover a greater vertical

+ * distance (and thus reduce the number of rectangles). Two bands can be merged

+ * only if the bottom of one touches the top of the other and they have

+ * rectangles in the same places (of the same width, of course).

+ *

+ * Adam de Boor wrote most of the original region code.  Joel McCormack

+ * substantially modified or rewrote most of the core arithmetic routines,

+ * and added miRegionValidate in order to support several speed improvements

+ * to miValidateTree.  Bob Scheifler changed the representation to be more

+ * compact when empty or a single rectangle, and did a bunch of gratuitous

+ * reformatting.

-/*****************************************************************
- * ReadRequestFromClient
- *    Returns one request in client->requestBuffer.  The request
- *    length will be in client->req_len.  Return status is:
- *
- *    > 0  if  successful, specifies length in bytes of the request
- *    = 0  if  entire request is not yet available
- *    < 0  if  client should be terminated
- *
- *    The request returned must be contiguous so that it can be
- *    cast in the dispatcher to the correct request type.  Because requests
- *    are variable length, ReadRequestFromClient() must look at the first 4
- *    or 8 bytes of a request to determine the length (the request length is
- *    in the 3rd and 4th bytes of the request unless it is a Big Request
- *    (see the Big Request Extension), in which case the 3rd and 4th bytes
- *    are zero and the following 4 bytes are the request length.
- *
- *    Note: in order to make the server scheduler (WaitForSomething())
- *    "fair", the ClientsWithInput mask is used.  This mask tells which
- *    clients have FULL requests left in their buffers.  Clients with
- *    partial requests require a read.  Basically, client buffers
- *    are drained before select() is called again.  But, we can't keep
- *    reading from a client that is sending buckets of data (or has
- *    a partial request) because others clients need to be scheduled.

+/*****************************************************************

+ * ReadRequestFromClient

+ *    Returns one request in client->requestBuffer.  The request

+ *    length will be in client->req_len.  Return status is:

+ *

+ *    > 0  if  successful, specifies length in bytes of the request

+ *    = 0  if  entire request is not yet available

+ *    < 0  if  client should be terminated

+ *

+ *    The request returned must be contiguous so that it can be

+ *    cast in the dispatcher to the correct request type.  Because requests

+ *    are variable length, ReadRequestFromClient() must look at the first 4

+ *    or 8 bytes of a request to determine the length (the request length is

+ *    in the 3rd and 4th bytes of the request unless it is a Big Request

+ *    (see the Big Request Extension), in which case the 3rd and 4th bytes

+ *    are zero and the following 4 bytes are the request length.

+ *

+ *    Note: in order to make the server scheduler (WaitForSomething())

+ *    "fair", the ClientsWithInput mask is used.  This mask tells which

+ *    clients have FULL requests left in their buffers.  Clients with

+ *    partial requests require a read.  Basically, client buffers

+ *    are drained before select() is called again.  But, we can't keep

+ *    reading from a client that is sending buckets of data (or has

+ *    a partial request) because others clients need to be scheduled.

-
-    Implementation Strategy
-
-    A bit vector is an obvious choice to represent the set, but may take
-    too much memory, depending on the numerically largest member in the
-    set.  One expected common case is for the client to ask for *all*
-    protocol.  This means it would ask for minor opcodes 0 through 65535.
-    Representing this as a bit vector takes 8K -- and there may be
-    multiple minor opcode intervals, as many as one per major (extension)
-    opcode).  In such cases, a list-of-intervals representation would be
-    preferable to reduce memory consumption.  Both representations will be
-    implemented, and RecordCreateSet will decide heuristically which one
-    to use based on the set members.

+

+    Implementation Strategy

+

+    A bit vector is an obvious choice to represent the set, but may take

+    too much memory, depending on the numerically largest member in the

+    set.  One expected common case is for the client to ask for *all*

+    protocol.  This means it would ask for minor opcodes 0 through 65535.

+    Representing this as a bit vector takes 8K -- and there may be

+    multiple minor opcode intervals, as many as one per major (extension)

+    opcode).  In such cases, a list-of-intervals representation would be

+    preferable to reduce memory consumption.  Both representations will be

+    implemented, and RecordCreateSet will decide heuristically which one

+    to use based on the set members.

-     * expensive, so we'll try to cull out any keys that are obviously okay:
-     * In any case:
-     *    - keys that have a group width <= the old width are okay (because
-     *      they could not possibly have been associated with the old type)
-     * If the key type increased in size:
-     *    - keys that already have a group width >= to the new width are okay
-     *    + keys that have a group width >= the old width but < the new width
-     *      might have to be enlarged.
-     * If the key type decreased in size:
-     *    - keys that have a group width > the old width don't have to be
-     *      resized (because they must have some other wider type associated 
-     *      with some group).
-     *    + keys that have a group width == the old width might have to be
-     *      shrunk.
-     * The possibilities marked with '+' require us to examine the key types
-     * associated with each group for the key.

+     *      might have to be enlarged.

+     * If the key type decreased in size:

-// U0326 replaced with dead_belowcomma.
-// 
-// Nov 29, 2008
-// dead_belowcomma has been added to keysymdef.h, so the U0326 can be replaced with
-// it, as long as the version of X11 is built with the new keysymdef.h file.
-// 
-// Nov 11, 2008.
-// (a) Changed <AC10> level 4 from Ooblique to Oslash. The two names are synonyms. Since level 3 is already
-//     specified as oslash, the change adds consistency.
-// (b) The new Finnish keyboard standard (SFS 5966) reserves <AB10> level 4 for U0326, the combining comma below. 
-//     Removed the previous dead_abovedot entry there and replaced it with U0326, which can be replaced
-//     with dead_commabelow if that is added to keysymdef.h.
-// 
-// Oct 10, 2007.
-// -Changed space column 3 to nobreakspace (from space).
-// -Changed UFE63 entries to dead_stroke.
-// 
-// Nov 29, 2006.
-// UFE63 can be changed to dead_stroke starting with version 7.0.7. of the X server.
-//
-// Dec 05, 2006.
-// Changed instances of NoSymbol in columns 3 and 4 to characters in columns 1 and 2.
-// This fixes a bug where the mappings couldn't be changed (with xmodmap for example).
-// NoSymbol left in other positions, so nothing is output from those key presses.
-//
-// Dec 11, 2006.
-// Changed all Uxxxx values to named versions.
-// If you have problems, check these defines (when compiling X):
-// XK_LATIN9: oe, OE.
-// XK_CURRENCY: EuroSign.
-// XK_LATIN2: caron.
-// XK_LATIN3: idotless.
-// XK_LATIN4: kra, eng, ENG.
-// XK_CAUCASUS: schwa, SCHWA.
-// XK_PUBLISHING: rightdoublequotemark, leftdoublequotemark, singlelowquotemark, doublelowquotemark, emdash,
-//                rightsinglequotemark, leftsinglequotemark, endash.
-// 
-// Unnamed positions: 
-// UFE63: dead_stroke. Will be fixed, once the entry is in keysymdef.h.
-// U0292: LATIN SMALL LETTER EZH. 
-// U01B7: LATIN CAPITAL LETTER EZH.
-// U2030: PER MILLE SIGN.
-//        Comment: XK_MillSign is U+20A5 MILL SIGN.
