-<title>Introduction</title>

-<sect2>
-<title>The Distributed Multihead X Server</title>
-
-<para>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.
-</para>
-
-<para>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.).
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Layout of Paper</title>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Development plan</title>
-
-<para>This section describes the development plan from approximately June
-2001 through July 2003.

-
-<sect2>
-<title>Bootstrap code</title>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Input device handling</title>
-
-<para>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'',
-</para>
-
-<para>There are some options as to how the front-end X server gets its core
-input devices:
-
-<orderedlist>
-<listitem>
- <para>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.
-</para>
-
- <para>The following options are available for implementing local input
- devices:
-
-<orderedlist>
-<listitem>
- <para>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.
-</para>
-</listitem>
-
-<listitem>
- <para>The <command>kdrive</command> 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
- <command>gpm</command> 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 <command>kdrive</command> drivers were not used for the DMX
- implementation.
-</para>
-</listitem>
-
-<listitem>
- <para>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.
-</para>
-</listitem>
-</orderedlist>
-</para>
-</listitem>
-
-<listitem>
- <para>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.
-</para>
-</listitem>
-
-<listitem>
- <para>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.
-</para>
-</listitem>
-
-<listitem>
- <para>Other options were initially explored, but they were all
- partial subsets of the options listed above and, hence, are
- irrelevant.
-</para>
-</listitem>
-
-</orderedlist>
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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):
-<orderedlist>
-<listitem>
- <para> A "dummy" device drive that never generates events.
-</para>
-</listitem>
-
-<listitem>
- <para> "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):
- <itemizedlist>
- <listitem><para>Linux keyboard</para></listitem>
- <listitem><para>Linux serial mouse (MS)</para></listitem>
- <listitem><para>Linux PS/2 mouse</para></listitem>
- <listitem><para>USB keyboard</para></listitem>
- <listitem><para>USB mouse</para></listitem>
- <listitem><para>USB generic device (e.g., joystick, gamepad, etc.)</para></listitem>
- </itemizedlist>
-</para>
-</listitem>
-
-<listitem>
- <para> "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.
-</para>
-</listitem>
-
-<listitem>
- <para> "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.

-<title>Output device handling</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<sect3>
-<title>Initialization</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>Handling rendering requests</title>
-
-<para>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:
-
-<orderedlist>
-<listitem>
- <para>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.
-</para>
-
- <para>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.
-</para>
-
- <para>The initial DMX implementation used a shadow framebuffer by
- default.
-</para>
-</listitem>
-
-<listitem>
- <para>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.
-</para>
-
- <para>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.
-</para>
-
- <para>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).
-</para>
-</listitem>
-
-</orderedlist>

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

-<sect2>
-<title>Optimizing DMX</title>
-
-<para>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.
-</para>
-
-<para>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).
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>Other potential optimizations will be determined from the performance
-analysis.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.

-<title>DMX X extension support</title>
-
-<para>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.
-</para>
-
-<para>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:

-<title>Common X extension support</title>
-
-<para>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.
-</para>
-
-<para>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.

-<title>OpenGL support</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>When the front and back-end servers are on different physical

-<title>Fonts</title>
-
-<para>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.

-<title>Zero width rendering primitives</title>
-
-<para>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.

-<title>Output scaling</title>
-
-<para>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

-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.

-<title>Core input device handling</title>
-
-<para>The following is a description of how core input devices are handled
-by an X server.
-</para>
-
-<sect3>
-<title>InitInput()</title>
-
-<para>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().
-</para>
-
-<para>InitInput() usually has implementation specific code to determine
-which input devices are available. For each input device it will be
-using, it calls AddInputDevice():
-
-<variablelist>
-<varlistentry>
-<term>AddInputDevice()</term>
-<listitem><para>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.
-</para></listitem>
-</varlistentry>
-</variablelist>
-</para>
-
-<para>Once input handles for core keyboard and core pointer devices have
-been obtained from AddInputDevice(). 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).
-</para>
-
-<para>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.

-</para></listitem></varlistentry>
-</variablelist>
-</para>
-
-<para>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():

-events, it can be registered here by calling the DIX function
-RegisterBlockAndWakeupHandlers(). (See the devReadInput() description
-below.)
-</para>
-</sect3>
-
-<sect3>
-<title>InitAndStartDevices()</title>
-
-<para>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.

-
-<para>For keyboard devices, this means specifying the keycode range,
-default keycode to keysym mapping, default modifier mapping, and the

-
-<para>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).

-<title>Output handling</title>
-
-<para>The following sections describe the main functions required to

-server.
-</para>
-
-<sect3>
-<title>InitOutput()</title>
-
-<para>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.
-</para>
-
-<para>The primary tasks for this function are outlined below:
-
-<orderedlist>
-<listitem>
- <para><emphasis remap="bf">Parse configuration info:</emphasis> 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.
-</para>
-</listitem>
-
-<listitem>
- <para><emphasis remap="bf">Initialize screen info:</emphasis> 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.
-</para>
-</listitem>
-
-<listitem>
- <para><emphasis remap="bf">Set pixmap formats:</emphasis> 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.
-</para>
-</listitem>
-
-<listitem>
- <para><emphasis remap="bf">Unify screen info:</emphasis> 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.
-</para>
-</listitem>
-</orderedlist>
-</para>
-
-<para>Once these tasks are complete, the valid screens are known and each
-of these screens can be initialized by calling AddScreen().
-</para>
-</sect3>
-
-<sect3>
-<title>AddScreen()</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>ScreenInit()</title>
-
-<para>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).
-</para>
-
-<para>The screen init function usually calls several functions to perform
-certain screen initialization functions. They are described below:

-<term>{mi,*fb}ScreenInit()</term>
-<listitem>
-<para>The DDX layer's ScreenInit() function usually

-fbScreenInit()) to initialize the fallbacks that the DDX driver does not
-specifically handle.
-</para>
-
-<para>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().
-</para></listitem></varlistentry>

-</para></listitem></varlistentry>
-</variablelist>
-</para>
-
-<para>Another common task for ScreenInit() function is to initialize the

-<title>CloseScreen()</title>

-private data it created during the screen initialization.
-</para>

-
-<sect3>
-<title>GC operations</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>Note that some pointers to functions that draw to the screen are
-stored in the Screen structure. They include GetImage(), GetSpans(),
-CopyWindow() and RestoreAreas().

-<title>Xnest</title>
-
-<para>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.

-<term>GC operations</term>
-<listitem>
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Shadow framebuffer</title>
-
-<para>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.
-</para>
-
-<para>There are two main entry points to the shadow framebuffer code:
-
-<variablelist>
-<varlistentry>
-<term>shadowAlloc(width, height, bpp)</term>
-<listitem>
-<para>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.
-</para></listitem></varlistentry>
-
-<varlistentry>
-<term>shadowInit(pScreen, updateProc, windowProc)</term>
-<listitem>
-<para>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).
-</para></listitem></varlistentry>
-</variablelist>
-</para>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Xinerama</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>The following is a code-level description of how Xinerama functions.
-</para>
-
-<para>Note: Because the Xinerama extension was originally called the
-PanoramiX extension, many of the Xinerama functions still have the
-PanoramiX prefix.
-</para>
-
-<variablelist>
-<varlistentry>
-<term>PanoramiXExtensionInit()</term>
-<listitem>
- <para>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.
- </para>
-
- <para>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.
- </para>
-
- <para>The Xinerama extension is registered by calling AddExtension().
- </para>
-
- <para>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.
- </para>
-
- <para>A region (PanoramiXScreenRegion) is
- initialized to be the union of the screen regions.
- The relative positioning information for the
- physical screens is taken from the ScreenRec x and y members, which
- the DDX layer must initialize in InitOutput(). The bounds of the
- combined screen is also calculated (PanoramiXPixWidth and
- PanoramiXPixHeight).
- </para>
-
- <para>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.

-<term>PanoramiXCreateConnectionBlock()</term>
-<listitem>
- <para>PanoramiXConsolidate() is a

- 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.
- </para>
-
- <para>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 <command>xdpyinfo</command> shows). The
- connection block is initialized with the combined single screen
- values that were calculated in the above two functions.
- </para>
-
- <para>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().

-<title>Xinerama-specific changes to the DIX code</title>
-
-<para>There are a few types of Xinerama-specific changes within the DIX
-code. The main ones are described here.
-</para>
-
-<para>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 &gt; 0. This is because they are handled for
-the single Xinerama screen and the processing is done once for screen 0.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>Xinerama-specific changes to the MI code</title>
-
-<para>The only Xinerama-specific change to the MI code is in miSendExposures()
-to handle the coordinate (and window ID) translation for expose events.
-</para>
-</sect3>
-
-<sect3>
-<title>Intercepted DIX core requests</title>
-
-<para>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.

-
-</para>
-
-<para>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).
-</para>
-</sect3>
-
-<sect3>
-<title>Results</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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 <emphasis remap="bf">-configfile</emphasis> and <emphasis remap="bf">-config</emphasis>
-command-line options can be used to start Xdmx using a configuration
-file.
-</para>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>X Test Suite</title>
-
- <sect4>
- <title>Introduction</title>
- <para>
- 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.
- </para>
- <para>
- 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.
- </para>
- </sect4>
-
- <sect4>
- <title>Expected Failures for a Single Head</title>
- <para>
- 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:
- <literallayout>
-XDrawArc: Tests 42, 63, 66, 73
-XDrawArcs: Tests 45, 66, 69, 76
- </literallayout>
- </para>
- <para>
- The following failures occur because of the high-level X
- server implementation:
- <literallayout>
-XLoadQueryFont: Test 1
-XListFontsWithInfo: Tests 3, 4
-XQueryFont: Tests 1, 2
- </literallayout>
- </para>
- <para>
- The following test fails when running the X server as root
- under Linux because of the way directory modes are
- interpreted:
- <literallayout>
-XWriteBitmapFile: Test 3
- </literallayout>
- </para>
- <para>
- 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.
- </para>
- </sect4>
-
- <sect4>
- <title>Expected Failures for Xinerama</title>
- <para>
- 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.
- </para>
-
- <para>
- 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.
- </para>
-
- <para>
- 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:
- </para>
-
- <para>
- These failures were noted with multiple Xinerama
- configurations:
- <literallayout>
-XCopyPlane: Tests 13, 22, 31 (well-known Xinerama implementation issue)
-XSetFontPath: Test 4
-XGetDefault: Test 5
-XMatchVisualInfo: Test 1

- These failures were noted only when using one dual-head
- video card with a 4.2.99.x XFree86 server:
- <literallayout>
-XListPixmapFormats: Test 1
-XDrawRectangles: Test 45
- </literallayout>
- </para>
- <para>
- These failures were noted only when using two video cards
- from different vendors with a 4.1.99.x XFree86 server:

- </para>
- </sect4>
-
- <sect4>
- <title>Additional Failures from Xdmx</title>
-
- <para>
- 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:
- <literallayout>
-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)
- </literallayout>
- </para>
- <para>
- 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.
- </para>
- </sect4>
-
- <sect4>
- <title>Summary and Future Work</title>
-
- <para>
- 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.
- </para>
-
- <para>
- 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.

-<title>Fonts</title>
-
-<para>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
-<emphasis remap="bf">the front- and back-end servers must share the exact same font
-path</emphasis>. There are two ways to help make sure that all servers share the
-same font path:
-
-<orderedlist>
- <listitem>
- <para>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.
- </para></listitem>
-
- <listitem>
- <para>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.
- </para></listitem>
-</orderedlist>
-</para>
-
-<para>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.
-</para>
-
-<para>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.

-<title>Performance</title>
-
-<para>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.
-</para>
-
-<orderedlist>
- <listitem>
- <para>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.

- <para>Sending drawing requests to only the screens that they overlap
- should improve performance.
- </para></listitem>
-</orderedlist>
-</sect3>
-
-<sect3>
-<title>Pixmaps</title>
-
-<para>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.

-<title>XSync() Batching</title>
-
-<para>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.
-</para>
-
-<para>Out of more than 300 <command>x11perf</command> 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.

-<title>Offscreen Optimization</title>
-
-<para>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.
-</para>
-
-<para>Out of more than 300 <command>x11perf</command> 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:
-<screen>
-0.88 Hide/expose window via popup (4 kids)
-0.89 Resize unmapped window (75 kids)

-<title>Lazy Window Creation Optimization</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>This optimization improved the following <command>x11perf</command> tests by more
-than 10%:

-<title>Subdividing Rendering Primitives</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>This optimization improved the following <command>x11perf</command> tests by more

-<title>Summary of x11perf Data</title>
-
-<para>With all of the optimizations on, 53 <command>x11perf</command> 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 <command>x11perf</command> tests.)

-<title>Profiling with OProfile</title>
-
-<para>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 <command>gprof</command>, 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 <command>x11perf</command> test individually.
-</para>
-
-<para>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 <command>gprof</command> output.
-This investigation has not produced results that yield performance
-increases in <command>x11perf</command> 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.

-<title>Phase III</title>
-
-<para>During the third phase of development, support was provided for the
-following extensions: SHAPE, RENDER, XKEYBOARD, XInput.
-</para>
-
-<sect3>
-<title>SHAPE</title>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>RENDER</title>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>XKEYBOARD</title>
-
-<para>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.
-</para>
-</sect3>
-
-<sect3>
-<title>XInput</title>
-
-<para>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.
-</para>
-
-<para>Currently, back-end extension devices are not available as Xdmx
-extension devices, but this limitation should be removed in the future.
-</para>
-
-<para>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

-<title>XC-MISC (supported)</title>
-
-<para>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 -->
-</para>
-</sect4>
-
-<sect4>
-<title>Extended-Visual-Information (supported)</title>
-
-<para>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 <filename>hw/dmx/examples/evi</filename> example
-program. <emphasis remap="bf">Note that this extension is not Xinerama-aware</emphasis> -- 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 -->
-</para>
-</sect4>
-
-<sect4>
-<title>RES (supported)</title>
-
-<para>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 <filename>hw/dmx/examples/res</filename> program. The
-X Test Suite passed and failed the exact same tests before and after
-this extension was enabled.
-<!-- Tested March 2003 -->
-</para>
-</sect4>
-
-<sect4>
-<title>BIG-REQUESTS (supported)</title>
-
-<para>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 -->
-</para>
-</sect4>
-
-<sect4>
-<title>XSYNC (supported)</title>
-
-<para>This extension provides facilities for two different X clients to
-synchronize their requests. This extension was minimally tested with
-<command>xdpyinfo</command> and the X Test Suite passed and failed the exact same
-tests before and after this extension was enabled.

-</sect4>
-
-<sect4>
-<title>XTEST, RECORD, DEC-XTRAP (supported) and XTestExtension1 (not supported)</title>
-
-<para>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
-<literal remap="tt">rcrdtest</literal> 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 -->
-</para>
-
-<para>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.
-</para>
-
-<para>The DEC-XTRAP extension is available from Xdmx and has been tested
-with the <command>xtrap*</command> tools which are distributed as standard X11R6
-clients. <!-- Tested March 2003 -->
-</para>
-
-<para>The XTestExtension1 is <emphasis>not</emphasis> 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 -->

-as expected. However, when Xinerama was active, <command>beforelight</command> did
-not behave as expected. Further, when this extension is not active,
-<command>xscreensaver</command> (a widely-used X screen saver program) did not behave

-<title>GLX (supported)</title>
-
-<para>The GLX extension provides OpenGL and GLX windowing support. In

-works by either feeding requests forward through Xdmx to each of the
-back-end servers or handling them locally. All rendering requests are

-project by SGI. For the X Test Suite results comparison, see below.

-<title>RENDER (supported)</title>
-
-<para>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.
-</para>
-
-<para>There is currently no test suite for the X Rendering Extension;
-however, there has been discussion of developing a test suite as the

-with and without using the XTEST extension. When the XTEST extension
-was <emphasis>not</emphasis> used for testing, the XFree86 4.3.0 server running on our

-<literallayout>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10

-</para>
-
-<para>While these errors may be important, they will probably be fixed

-<literallayout>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests 20, 21, 24

-XDrawLine: Test 67
-XDrawLines: Test 91
-XDrawSegments: Test 68
-</literallayout>
-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.

-
-<sect4>
-<title>Xdmx with XTEST, with Xinerama, with GLX</title>
-
-<para>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):
-<literallayout>
-XListPixmapFormats: Test 1
-XChangeKeyboardControl: Tests 9, 10
-XRebindKeysym: Test 1
-
-XAllowEvents: Tests 20, 21, 24

-XDrawArcs: Tests 89, 100, 102
-XDrawLine: Test 67
-XDrawSegments: Test 68
-</literallayout>
-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.
-</para>
-
-<para>Further, when hardware rendering is disabled on the back-end displays,
-many of the errors in the third set are eliminated, leaving only:
-<literallayout>
-XClearArea: Test 8
-XCopyArea: Test 4, 5, 11, 14, 17, 23, 25, 27, 30

-<sect4>
-<title>Conclusion</title>
-
-<para>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.)

-<title>Dynamic Reconfiguration</title>
-
-<para>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.
-</para>
-
-<sect4>
-<title>Dynamic reconfiguration extension</title>
-
-<para>The application interface to DMX's dynamic reconfiguration is through
-a function in the DMX extension library:
-<programlisting>
-Bool DMXReconfigureScreen(Display *dpy, int screen, int x, int y)
-</programlisting>
-where <parameter>dpy</parameter> is DMX server's display, <parameter>screen</parameter> is the number of the
-screen to be reconfigured, and <parameter>x</parameter> and <parameter>y</parameter> are the new upper,
-left-hand coordinates of the screen to be reconfigured.
-</para>
-
-<para>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.
-</para>
-</sect4>
-
-<sect4>
-<title>Bounding box</title>
-
-<para>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.
-</para>
-
-<para>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.
-</para>
-
-<para>This fixed bounding box limitation will be addressed in a future
-development phase.

-
-<para>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.
-</para>
-
-<para>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.
-</para>

-<para>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 <filename>dmxreconfig.c</filename> for details.

-<title>Additional notes</title>
-
-<para>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).

+<title>Introduction</title>
+
+<sect2>
+<title>The Distributed Multihead X Server</title>
+
+<para>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.
+</para>
+
+<para>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.).
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.

+<title>Layout of Paper</title>
+
+<para>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.
+</para>
+
+<para>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.

+<title>Bootstrap code</title>
+
+<para>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.
+</para>
+
+<para>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.

+<title>Input device handling</title>
+
+<para>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'',
+</para>
+
+<para>There are some options as to how the front-end X server gets its core
+input devices:
+
+<orderedlist>
+<listitem>
+ <para>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.
+</para>
+
+ <para>The following options are available for implementing local input
+ devices:
+
+<orderedlist>
+<listitem>
+ <para>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.
+</para>
+</listitem>
+
+<listitem>
+ <para>The <command>kdrive</command> 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
+ <command>gpm</command> 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 <command>kdrive</command> drivers were not used for the DMX
+ implementation.
+</para>
+</listitem>
+
+<listitem>
+ <para>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.
+</para>
+</listitem>
+</orderedlist>
+</para>
+</listitem>
+
+<listitem>
+ <para>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.
+</para>
+</listitem>
+
+<listitem>
+ <para>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.
+</para>
+</listitem>
+
+<listitem>
+ <para>Other options were initially explored, but they were all
+ partial subsets of the options listed above and, hence, are
+ irrelevant.
+</para>
+</listitem>
+
+</orderedlist>
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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):
+<orderedlist>
+<listitem>
+ <para> A "dummy" device drive that never generates events.
+</para>
+</listitem>
+
+<listitem>
+ <para> "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

+</listitem>
+
+<listitem>
+ <para> "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.

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

+ 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

+<title>Output device handling</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<sect3>
+<title>Initialization</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+</sect3>
+
+<sect3>
+<title>Handling rendering requests</title>
+
+<para>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:
+
+<orderedlist>
+<listitem>
+ <para>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.
+</para>
+
+ <para>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.
+</para>
+
+ <para>The initial DMX implementation used a shadow framebuffer by
+ default.
+</para>
+</listitem>
+
+<listitem>
+ <para>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.
+</para>
+
+ <para>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.
+</para>
+
+ <para>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).
+</para>
+</listitem>
+
+</orderedlist>
+</para>
+
+<para>Status: Both the shadow framebuffer and Xnest-style code is complete.

+
+<sect2>
+<title>Optimizing DMX</title>
+
+<para>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.
+</para>
+
+<para>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).
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>Other potential optimizations will be determined from the performance
+analysis.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>Status: The optimizations proposed above are complete. It was

+<title>DMX X extension support</title>
+
+<para>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.

+<title>Common X extension support</title>
+
+<para>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.
+</para>
+
+<para>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.

+<title>OpenGL support</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.

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

+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.

+<title>Zero width rendering primitives</title>
+

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

+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.

+<title>Core input device handling</title>
+
+<para>The following is a description of how core input devices are handled
+by an X server.
+</para>
+
+<sect3>
+<title>InitInput()</title>
+
+<para>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().
+</para>
+
+<para>InitInput() usually has implementation specific code to determine
+which input devices are available. For each input device it will be
+using, it calls AddInputDevice():
+
+<variablelist>
+<varlistentry>
+<term>AddInputDevice()</term>
+<listitem><para>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.
+</para></listitem>
+</varlistentry>
+</variablelist>
+</para>
+
+<para>Once input handles for core keyboard and core pointer devices have
+been obtained from AddInputDevice(). 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).
+</para>
+
+<para>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.

+pointer's input handle with with the miPointer code.
+</para></listitem></varlistentry>
+</variablelist>
+</para>
+
+<para>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():

+
+<sect3>
+<title>InitAndStartDevices()</title>
+
+<para>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.

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

+ ddxProcessArgument() function, which is called by
+ ProcessCommandLine(). The configuration information determines the
+ characteristics of the screen(s). For example, in the XFree86 X

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

+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.

+
+<para>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.

+<term>GC operations</term>
+<listitem>
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.

+<title>Shadow framebuffer</title>
+
+<para>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.

+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).
+</para></listitem></varlistentry>
+</variablelist>
+</para>

+<title>Xinerama</title>
+
+<para>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.
+</para>
+
+<para>The current implementation of Xinerama is based primarily in the DIX
+(device independent) and MI (machine independent) layers of the X

+provide full Xinerama functionality.

+ 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

+<title>Results</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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 <emphasis remap="bf">-configfile</emphasis> and <emphasis remap="bf">-config</emphasis>
+command-line options can be used to start Xdmx using a configuration
+file.
+</para>
+
+<para>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.

+ <sect4>
+ <title>Introduction</title>
+ <para>
+ 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.
+ </para>
+ <para>
+ The Xdmx server was tested with the X Test Suite, and the

+ results in perspective, we first discuss expected X Test
+ failures and how errors in underlying systems can impact
+ Xdmx test results.

+
+ <sect4>
+ <title>Expected Failures for a Single Head</title>
+ <para>
+ A correctly implemented X server with a single screen is
+ expected to fail certain X Test tests. The following

+XDrawArcs: Tests 45, 66, 69, 76

+ </para>
+ <para>
+ Depending on the video card used for the back-end, other

+ are usually fixed by XFree86, but will show up in Xdmx
+ testing until then.

+ </sect4>
+
+ <sect4>
+ <title>Expected Failures for Xinerama</title>
+ <para>
+ 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.

+ <para>
+ Xinerama is constantly improving, and the list of
+ Xinerama-related failures depends on XFree86 version and
+ the underlying graphics hardware. We tested with a

+
+ <sect4>
+ <title>Additional Failures from Xdmx</title>
+
+ <para>
+ 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:
+ <literallayout>
+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)
+ </literallayout>
+ </para>
+ <para>
+ 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.
+ </para>
+ </sect4>
+
+ <sect4>
+ <title>Summary and Future Work</title>
+
+ <para>
+ 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.
+ </para>
+
+ <para>
+ 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.

+<title>Fonts</title>
+
+<para>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
+<emphasis remap="bf">the front- and back-end servers must share the exact same font
+path</emphasis>. There are two ways to help make sure that all servers share the
+same font path:
+
+<orderedlist>
+ <listitem>
+ <para>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.
+ </para></listitem>
+
+ <listitem>
+ <para>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.
+ </para></listitem>
+</orderedlist>
+</para>
+
+<para>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.
+</para>
+
+<para>The -fontpath command line option was added to allow users to
+initialize the font path of the front end server. This font path is

+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.

+<title>Phase II</title>
+
+<para>The second phase of development concentrates on performance
+optimizations. These optimizations are documented here, with
+<command>x11perf</command> data to show how the optimizations improve performance.
+</para>
+
+<para>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.

+
+<sect3>
+<title>Moving from XFree86 4.1.99.1 to 4.2.0.0</title>
+
+<para>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:

+<title>XSync() Batching</title>
+
+<para>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.
+</para>
+
+<para>Out of more than 300 <command>x11perf</command> 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.

+<title>Offscreen Optimization</title>
+
+<para>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.
+</para>
+
+<para>Out of more than 300 <command>x11perf</command> 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:
+<screen>
+0.88 Hide/expose window via popup (4 kids)
+0.89 Resize unmapped window (75 kids)
+</screen>
+</para>
+</sect3>
+
+<sect3>
+<title>Lazy Window Creation Optimization</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>This optimization improved the following <command>x11perf</command> tests by more
+than 10%:

+<title>Subdividing Rendering Primitives</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>This optimization improved the following <command>x11perf</command> tests by more

+<title>Profiling with OProfile</title>
+
+<para>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 <command>gprof</command>, 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 <command>x11perf</command> test individually.
+</para>
+
+<para>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 <command>gprof</command> output.
+This investigation has not produced results that yield performance
+increases in <command>x11perf</command> 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.

+<title>Phase III</title>
+
+<para>During the third phase of development, support was provided for the
+following extensions: SHAPE, RENDER, XKEYBOARD, XInput.
+</para>
+
+<sect3>
+<title>SHAPE</title>
+
+<para>The SHAPE extension is supported. Test applications (e.g., xeyes and

+work as expected.

+
+<sect3>
+<title>RENDER</title>
+
+<para>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.
+</para>
+</sect3>
+
+<sect3>
+<title>XKEYBOARD</title>
+
+<para>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.
+</para>
+</sect3>
+
+<sect3>
+<title>XInput</title>
+
+<para>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.
+</para>
+
+<para>Currently, back-end extension devices are not available as Xdmx
+extension devices, but this limitation should be removed in the future.
+</para>
+
+<para>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

+<title>XC-MISC (supported)</title>
+
+<para>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.

+
+<sect4>
+<title>Extended-Visual-Information (supported)</title>
+
+<para>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 <filename>hw/dmx/examples/evi</filename> example
+program. <emphasis remap="bf">Note that this extension is not Xinerama-aware</emphasis> -- it will

+

+<title>RES (supported)</title>
+
+<para>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 <filename>hw/dmx/examples/res</filename> program. The
+X Test Suite passed and failed the exact same tests before and after
+this extension was enabled.

+<title>XSYNC (supported)</title>
+

+<title>XTEST, RECORD, DEC-XTRAP (supported) and XTestExtension1 (not supported)</title>
+
+<para>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
+<literal remap="tt">rcrdtest</literal> 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 -->
+</para>
+
+<para>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.
+</para>
+
+<para>The DEC-XTRAP extension is available from Xdmx and has been tested
+with the <command>xtrap*</command> tools which are distributed as standard X11R6
+clients. <!-- Tested March 2003 -->
+</para>
+
+<para>The XTestExtension1 is <emphasis>not</emphasis> 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 -->
+</para>

+<para>Most of these extensions are documented in the X11R6 source tree.

+not behave as expected. Further, when this extension is not active,
+<command>xscreensaver</command> (a widely-used X screen saver program) did not behave

+<title>GLX (supported)</title>

+<title>RENDER (supported)</title>
+
+<para>The X Rendering Extension (RENDER) provides support for digital image

+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

+
+<para>There is currently no test suite for the X Rendering Extension;
+however, there has been discussion of developing a test suite as the

+Note that the first two sets of errors are the same as for the XFree86

+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.
+</para>
+
+<para>Further, when hardware rendering is disabled on the back-end displays,
+many of the errors in the third set are eliminated, leaving only:

+<title>Conclusion</title>
+
+<para>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.)
+</para>
+</sect4>
+</sect3>
+
+<sect3>
+<title>Dynamic Reconfiguration</title>
+
+<para>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.
+</para>
+
+<sect4>
+<title>Dynamic reconfiguration extension</title>
+
+<para>The application interface to DMX's dynamic reconfiguration is through
+a function in the DMX extension library:
+<programlisting>
+Bool DMXReconfigureScreen(Display *dpy, int screen, int x, int y)
+</programlisting>
+where <parameter>dpy</parameter> is DMX server's display, <parameter>screen</parameter> is the number of the
+screen to be reconfigured, and <parameter>x</parameter> and <parameter>y</parameter> are the new upper,
+left-hand coordinates of the screen to be reconfigured.
+</para>
+
+<para>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.
+</para>
+</sect4>
+
+<sect4>
+<title>Bounding box</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>This fixed bounding box limitation will be addressed in a future
+development phase.
+</para>
+</sect4>
+
+<sect4>
+<title>Sample applications</title>
+
+<para>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.
+</para>
+
+<para>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.
+</para>
+
+<para>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 <filename>dmxreconfig.c</filename> for details.
+</para>
+</sect4>
+
+<sect4>
+<title>Additional notes</title>
+
+<para>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).
+</para>
+</sect4>
+</sect3>
+
+<sect3>
+<title>Doxygen documentation</title>
+
+<para>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.
+</para>
+</sect3>
+
+<sect3>
+<title>Valgrind</title>
+
+<para>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:
+<orderedlist>
+ <listitem><para>
+ 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.
+ </para></listitem>
+ <listitem><para>
+ 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.
+ </para></listitem>
+ <listitem><para>
+ 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.
+ </para></listitem>
+</orderedlist>
+</para>
+</sect3>
+
+<sect3>
+<title>RATS</title>
+
+<para>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:
+<orderedlist>
+ <listitem><para>
+ Fixed-size buffers are used in many areas, but code has been
+ added to protect against buffer overflows (e.g., snprintf).
+ 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.
+ </para></listitem>
+ <listitem><para>
+ 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.
+ </para></listitem>
+ <listitem><para>
+ 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).

+Three equations combine to describe the boundaries of the arc
+
+x^2/w^2 + y^2/h^2 = 1 ellipse itself
+(X-x)^2 + (Y-y)^2 = r^2 circle at (x, y) on the ellipse
+(Y-y) = (X-x)*w^2*y/(h^2*x) normal at (x, y) on the ellipse
+
+These lead to a quartic relating Y and y
+
+y^4 - (2Y)y^3 + (Y^2 + (h^4 - w^2*r^2)/(w^2 - h^2))y^2
+ - (2Y*h^4/(w^2 - h^2))y + (Y^2*h^4)/(w^2 - h^2) = 0
+
+The reducible cubic obtained from this quartic is
+
+z^3 - (3N)z^2 - 2V = 0
+
+where
+
+N = (Y^2 + (h^4 - w^2*r^2/(w^2 - h^2)))/6
+V = w^2*r^2*Y^2*h^4/(4 *(w^2 - h^2)^2)
+
+Let
+
+t = z - N
+p = -N^2
+q = -N^3 - V
+
+Then we get
+
+t^3 + 3pt + 2q = 0
+
+The discriminant of this cubic is
+
+D = q^2 + p^3
+
+When D > 0, a real root is obtained as
+
+z = N + cbrt(-q+sqrt(D)) + cbrt(-q-sqrt(D))
+
+When D < 0, a real root is obtained as
+
+z = N - 2m*cos(acos(-q/m^3)/3)
+
+where
+
+m = sqrt(|p|) * sign(q)
+
+Given a real root Z of the cubic, the roots of the quartic are the roots
+of the two quadratics
+
+y^2 + ((b+A)/2)y + (Z + (bZ - d)/A) = 0
+
+where
+
+A = +/- sqrt(8Z + b^2 - 4c)
+b, c, d are the cubic, quadratic, and linear coefficients of the quartic
+
+Some experimentation is then required to determine which solutions
+correspond to the inner and outer boundaries.

- * = 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

- * are variable length, ReadRequestFromClient() must look at the first 4
- * or 8 bytes of a request to determine the length (the request length is

- * Note: in order to make the server scheduler (WaitForSomething())
- * "fair", the ClientsWithInput mask is used. This mask tells which
- * clients have FULL requests left in their buffers. Clients with
- * partial requests require a read. Basically, client buffers
- * are drained before select() is called again. But, we can't keep
- * reading from a client that is sending buckets of data (or has
- * a partial request) because others clients need to be scheduled.
