-** File:
-**
-** 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.

+** File:
+**
+** 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
+ * 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

-/* 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.

-/** \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.

-<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>

-
-<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.

-<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>

-
-<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.

-<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:
- <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:

-<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:

-0.89 Resize unmapped window (75 kids)

-
-<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%:

-
-<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.

-<!-- ============================================================ -->
-<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.
-
-<p>The
- BIG-REQUESTS,

- XC-MISC,
- XFree86-DGA,

- XVideo
-extensions are <it/not/ supported at this time, but will be evaluated
-for inclusion in future DMX releases. <bf>See below for additional work
-on extensions after Phase III.</bf>
-
-<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.

-
-<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).

+<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.

+<!-- 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,
+ DMX,
+ DPMS,
+ Extended-Visual-Information,
+ GLX,
+ LBX,
+ RECORD,

+ XInputExtension,
+ XKEYBOARD, and
+ XTEST.
+<!-- November 2002; updated February 2003, July 2003 -->
+
+<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)
+1.26 PutImage 10x10 square
+1.83 PutImage 100x100 square

+1.50 PutImage XY 500x500 square
+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:

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

+for inclusion in future DMX releases. <bf>See below for additional work
+on extensions after Phase III.</bf>
+
+<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.

+
+<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).
+</enum>

- * xf86ValidateModes
- *
- * This function takes a set of mode names, modes and limiting conditions,

- * This function takes the following parameters:
- * scrp ScrnInfoPtr
- * availModes the list of modes available for the monitor
- * modeNames (optional) list of mode names that the screen is requesting
- * clockRanges a list of clock ranges
- * linePitches (optional) a list of line pitches
- * minPitch (optional) minimum line pitch (in pixels)
- * maxPitch (optional) maximum line pitch (in pixels)
- * pitchInc (mandatory) pitch increment (in bits)
- * minHeight (optional) minimum virtual height (in pixels)
- * maxHeight (optional) maximum virtual height (in pixels)
- * virtualX (optional) virtual width requested (in pixels)
- * virtualY (optional) virtual height requested (in pixels)
- * apertureSize size of video aperture (in bytes)
- * strategy how to decide which mode to use from multiple modes with
- * the same name
- *
- * In addition, the following fields from the ScrnInfoRec are used:
- * clocks a list of discrete clocks
- * numClocks number of discrete clocks
- * progClock clock is programmable
- * monitor pointer to structure for monitor section
- * fbFormat format of the framebuffer
- * videoRam video memory size
- * maxHValue maximum horizontal timing value
- * maxVValue maximum vertical timing value
- * xInc horizontal timing increment (defaults to 8 pixels)
- *
- * The function fills in the following ScrnInfoRec fields:
- * modePool A subset of the modes available to the monitor which
- * are compatible with the driver.
- * modes one mode entry for each of the requested modes, with the
- * status field filled in to indicate if the mode has been
- * accepted or not.
- * virtualX the resulting virtual width
- * virtualY the resulting virtual height
- * displayWidth the resulting line pitch
- *
- * The function's return value is the number of matching modes found, or -1

- * OK, so much for theory. Now, let's deal with the >real< world...
- *
- * The above CRTC settings are precise in theory, except that many, if not
- * most, VGA clones fail to reset the blanking signal when the character or
- * line counter reaches [HV]Total. In this case, the signal is only
- * unblanked when the counter reaches [HV]BlankEnd (mod 64, 128 or 256 as
- * the case may be) at the start of the >next< scanline or frame, which
- * 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.

+ * OK, so much for theory. Now, let's deal with the >real< world...
+ *
+ * The above CRTC settings are precise in theory, except that many, if not
+ * most, VGA clones fail to reset the blanking signal when the character or
+ * line counter reaches [HV]Total. In this case, the signal is only
+ * unblanked when the counter reaches [HV]BlankEnd (mod 64, 128 or 256 as
+ * the case may be) at the start of the >next< scanline or frame, which
+ * 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,

+ 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.

- wglMakeCurrent ignores the hdc if hglrc is NULL, so wglMakeCurrent(NULL, NULL)

- * 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.

- * = 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

- * 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

- * 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

+ * 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

-// 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.
-// Per mille is a generic term for 1/1000. Mill is 1/1000 of a dollar.
