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. - - - 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.). - - - 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. - - - 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. - - - 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. - - - 11..22.. LLaayyoouutt ooff PPaappeerr - - 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. - - - 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. - - - 22.. DDeevveellooppmmeenntt ppllaann - - This section describes the development plan from approximately June - 2001 through July 2003. - - - - 22..11.. BBoooottssttrraapp ccooddee - - 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. - - - 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. - - - Status: The boot strap code is complete. - - - - 22..22.. IInnppuutt ddeevviiccee hhaannddlliinngg - - 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'', - - - There are some options as to how the front-end X server gets its core - input devices: - - - 1. 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. - - - The following options are available for implementing local input - devices: - - - a. 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. - - - b. The kdrive X server in XFree86 has built-in drivers that support - PS/2 mice and keyboard under Linux. The mouse driver can - indirectly handle other mouse types if the Linux utility gpm is - used as to translate the native mouse protocol into PS/2 mouse - format. These drivers could be adapted and built in to the - front-end X server if this range of hardware and OS support is - sufficient. While much simpler than the XFree86 drivers, the - kdrive drivers were not used for the DMX implementation. - - c. 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. - - - 2. 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. - - 3. 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. - - 4. Other options were initially explored, but they were all partial - subsets of the options listed above and, hence, are irrelevant. - - - 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. - - - 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. - - - 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): - - 1. A "dummy" device drive that never generates events. - - 2. "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): - - +o Linux keyboard - - +o Linux serial mouse (MS) - - +o Linux PS/2 mouse - - +o USB keyboard - - +o USB mouse - - +o USB generic device (e.g., joystick, gamepad, etc.) - - - 3. "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. - - 4. "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. - - - - 22..33.. OOuuttppuutt ddeevviiccee hhaannddlliinngg - - 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. - - - 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. - - - 22..33..11.. IInniittiiaalliizzaattiioonn - - 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. - - - 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. - - - 22..33..22.. HHaannddlliinngg rreennddeerriinngg rreeqquueessttss - - 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: - - - 1. 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. - - - 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. - - - The initial DMX implementation used a shadow framebuffer by - default. - - - 2. 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. - - - 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. - - - 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). - - - - Status: Both the shadow framebuffer and Xnest-style code is complete. - - - - 22..44.. OOppttiimmiizziinngg DDMMXX - - 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. - - - 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). - - - 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. - - - 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. - - - 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. - - - Other potential optimizations will be determined from the performance - analysis. - - 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. - - - 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. - - - 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. - - - - 22..55.. DDMMXX XX eexxtteennssiioonn ssuuppppoorrtt - - 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. - - - 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: - - 1. Screen information (clipping rectangle for each screen relative to - the virtual screen) - - 2. Window information (window IDs and clipping information for each - back-end window that corresponds to each DMX window) - - 3. Input device information (mappings from DMX device IDs to back-end - device IDs) - - 4. Force window creation (so that a client can override the server- - side lazy window creation optimization) - - 5. Reconfiguration (so that a client can request that a screen - position be changed) - - 6. Addition and removal of back-end servers and back-end and console - inputs. - 22..66.. CCoommmmoonn XX eexxtteennssiioonn ssuuppppoorrtt - - 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. - - - 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. - - - Support for the XTest extension was added during the first development - phase. - - - Status: The following extensions are supported and are discussed in - more detail in Phase IV of the Development Results (see appendix): - BIG-REQUESTS, DEC-XTRAP, DMX, DPMS, Extended-Visual-Information, GLX, - LBX, RECORD, RENDER, SECURITY, SHAPE, SYNC, X-Resource, XC-APPGROUP, - XC-MISC, XFree86-Bigfont, XINERAMA, XInputExtension, XKEYBOARD, and - XTEST. - - - 22..77.. OOppeennGGLL ssuuppppoorrtt - - 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. - - - 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. - - - 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. - - - 1. The existing OpenGL support in each back-end server can be used by - repackaging rendering primitives and sending them to each back-end - server. This option is similar to the unoptimized Xnest-style - approach mentioned above. Optimization of this solution is beyond - the scope of this project and is better suited to other distributed - rendering systems. - - 2. Rendering to a pixmap in the front-end server using the current - XFree86 4.x code, and then displaying to the back-ends via calls to - XPutImage() is another option. This option is similar to the - shadow frame buffer approach mentioned above. It is slower and - bandwidth intensive, but has the advantage that the back-end - servers are not required to have OpenGL support. - - - These, and other, options will be investigated in this phase of the - work. - - - Work by others have made Chromium DMX-aware. Chromium will use the - DMX X protocol extension to obtain information about the back-end - servers and will render directly to those servers, bypassing DMX. - - - Status: OpenGL support by the glxProxy extension was implemented by - SGI and has been integrated into the DMX code base. - - - - 33..

FFoonnttss - - 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. - - - 33..22.. ZZeerroo wwiiddtthh rreennddeerriinngg pprriimmiittiivveess - - 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. - - - 33..33.. OOuuttppuutt ssccaalliinngg - - With very large tiled displays, it might be difficult to read the - information on the standard X desktop. In particular, the cursor can - be easily lost and fonts could be difficult to read. Automatic - primitive scaling might prove to be very useful. We will investigate - the possibility of scaling the cursor and providing a set of alternate - pre-scaled fonts to replace the standard fonts that many applications - use (e.g., fixed). Other options for automatic scaling will also be - investigated. - - - - 33..44.. PPeerr--ssccrreeeenn ccoolloorrmmaappss - - Each screen's default colormap in the set of back-end X servers should - be able to be adjusted via a configuration utility. This support is - would allow the back-end screens to be calibrated via custom gamma - tables. On 24-bit systems that support a DirectColor visual, this - type of correction can be accommodated. One possible implementation - would be to advertise to X client of the DMX server a TrueColor visual - while using DirectColor visuals on the back-end servers to implement - this type of color correction.

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(). - - - InitInput() usually has implementation specific code to determine - which input devices are available. For each input device it will be - using, it calls AddInputDevice(): - - - AAddddIInnppuuttDDeevviiccee(()) - 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.

While this registration - is not necessary for correct miPointer operation in the current - XFree86 code, it is still done mostly for compatibility reasons. - - - mmiiRReeggiisstteerrPPooiinntteerrDDeevviiccee(()) - This MI function registers the core pointer's input handle with - with the miPointer code. - - - 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.

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). - - - Events are queued by calling mieqEnqueue(): - - - mmiieeqqEEnnqquueeuuee(()) - This MI function is used to add input events to the event queue. - It is simply passed the event to be queued. - - - The cursor position should be updated when motion events are enqueued, - by calling either miPointerAbsoluteCursor() or miPointerDeltaCursor(): - - - mmiiPPooiinntteerrAAbbssoolluutteeCCuurrssoorr(()) - This MI function is used to move the cursor to the absolute - coordinates provided. - - mmiiPPooiinntteerrDDeellttaaCCuurrssoorr(()) - This MI function is used to move the cursor relative to its - current position. - - - AA..11..44.. PPrroocceessssIInnppuuttEEvveennttss(()) - - ProcessInputEvents() is a DDX function that is called from the X - server's main dispatch loop when new events are available in the input - event queue.

DisableDevice() may be called from the DDX when it is - desirable to do so (e.g., the XFree86 server does this when VT - switching). Except for special cases, this is not normally called for - core input devices. - - - DisableDevice() calls the device's callback function with DEVICE_OFF: - - - ((**ddeevv-->>ddeevviicceePPrroocc))((ddeevv,, DDEEVVIICCEE__OOFFFF)) - This typically closes the relevant physical device, and when - appropriate, unregisters the device's file descriptor (or - equivalent) as a valid input source. - - - DisableDevice() then removes the device handle from the X server's - global list of enabled devices. - - - - AA..11..66..

IInniittOOuuttppuutt(()) - - 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. - - - The primary tasks for this function are outlined below: - - - 1. PPaarrssee ccoonnffiigguurraattiioonn iinnffoo:: 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. - - 2. IInniittiiaalliizzee ssccrreeeenn iinnffoo:: 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[] structure. - - 3. SSeett ppiixxmmaapp ffoorrmmaattss:: 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. - - 4. UUnniiffyy ssccrreeeenn iinnffoo:: 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. - - Once these tasks are complete, the valid screens are known and each of - these screens can be initialized by calling AddScreen(). - - - AA..22..22.. AAddddSSccrreeeenn(()) - - 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. - - - 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. - - - AA..22..33.. SSccrreeeennIInniitt(()) - - 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). - - - The screen init function usually calls several functions to perform - certain screen initialization functions. They are described below: - - - {{mmii,,**ffbb}}SSccrreeeennIInniitt(()) - The DDX layer's ScreenInit() function usually calls another - layer's ScreenInit() function (e.g., miScreenInit() or - fbScreenInit()) to initialize the fallbacks that the DDX driver - does not specifically handle. - - - 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(). - - - mmiiIInniittiiaalliizzeeBBaacckkiinnggSSttoorree(()) - This MI function initializes the screen's backing storage - functions, which are used to save areas of windows that are - currently covered by other windows. - - - mmiiDDCCIInniittiiaalliizzee(()) - This MI function initializes the MI cursor display structures - and function pointers. If a hardware cursor is used, the DDX - layer's ScreenInit() function will wrap additional screen and - the MI cursor display function pointers. - - - Another common task for ScreenInit() function is to initialize the - output device state. For example, in the XFree86 X server, the - ScreenInit() function saves the original state of the video card and - then initializes the video mode of the graphics device. - - AA..22..44.. CClloosseeSSccrreeeenn(()) - - This function restores any wrapped screen functions (and in particular - the wrapped CloseScreen() function) and restores the state of the - output device to its original state. It should also free any private - data it created during the screen initialization. - - - AA..22..55.. GGCC ooppeerraattiioonnss - - 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. - - - 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. - - - Note that some pointers to functions that draw to the screen are - stored in the Screen structure. They include GetImage(), GetSpans(), - PaintWindowBackground(), PaintWindowBorder(), CopyWindow() and - RestoreAreas(). - - - AA..22..66.. XXnneesstt - - 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. - - - The Xnest server implements all of the standard input and output - initialization steps outlined above. - - - IInniittOOuuttppuutt(()) - Xnest takes its configuration information from command line - arguments via ddxProcessArguments(). This information includes - the real X server display to connect to, its default visual - class, the screen depth, the Xnest window's geometry, etc. - Xnest then connects to the real X server and gathers visual, - colormap, depth and pixmap information about that server's - display, creates a window on that server, which will be used as - the root window for Xnest. - - - Next, Xnest initializes its internal data structures and uses - the data from the real X server's pixmaps to initialize its own - pixmap formats. Finally, it calls AddScreen(xnestOpenScreen, - argc, argv) to initialize each of its screens. - SSccrreeeennIInniitt(()) - Xnest's ScreenInit() function is called xnestOpenScreen(). This - function initializes its screen's depth and visual information, - and then calls miScreenInit() to set up the default screen - functions. It then calls miInitializeBackingStore() and - miDCInitialize() to initialize backing store and the software - cursor. Finally, it replaces many of the screen functions with - its own functions that repackage and send the requests to the - real X server to which Xnest is attached. - - - CClloosseeSSccrreeeenn(()) - This function frees its internal data structure allocations. - Since it replaces instead of wrapping screen functions, there - are no function pointers to unwrap. This can potentially lead - to problems during server regeneration. - - - GGCC ooppeerraattiioonnss - 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. - - - 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. - - - 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. - - - The Xnest server takes its input from the X server to which it is - connected. When the mouse is in the Xnest server's window, keyboard - and mouse events are received by the Xnest server, repackaged and sent - back to any client that requests those events. - - - AA..22..77.. SShhaaddooww ffrraammeebbuuffffeerr - - 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. - - - There are two main entry points to the shadow framebuffer code: - - - sshhaaddoowwAAlllloocc((wwiiddtthh,, hheeiigghhtt,, bbpppp)) - 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. - - - sshhaaddoowwIInniitt((ppSSccrreeeenn,, uuppddaatteePPrroocc,, wwiinnddoowwPPrroocc)) - 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). - - - 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. - - - 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. - - - - AA..33.. XXiinneerraammaa - - 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. - - - 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. - - - The following is a code-level description of how Xinerama functions. - - - Note: Because the Xinerama extension was originally called the - PanoramiX extension, many of the Xinerama functions still have the - PanoramiX prefix. - - - PPaannoorraammiiXXEExxtteennssiioonnIInniitt(()) - 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. - - - 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. - - - The Xinerama extension is registered by calling AddExtension(). - - - A local per-screen array of data structures (panoramiXdataPtr[]) - is allocated for each physical screen, and GC and Screen private - indexes are allocated, and both GC and Screen private areas are - allocated for each physical screen. These hold Xinerama- - specific per-GC and per-Screen data. Each screen's CreateGC and - CloseScreen functions are wrapped by XineramaCreateGC() and - XineramaCloseScreen() respectively. Some new resource classes - are created for Xinerama drawables and GCs, and resource types - for Xinerama windows, pixmaps and colormaps. - - - A region (XineramaScreenRegions[i]) is initialized for each - physical screen, and single region (PanoramiXScreenRegion) is - initialized to be the union of the screen regions. The - panoramiXdataPtr[] array is also initialized with the size and - origin of each screen. The relative positioning information for - the physical screens is taken from the array dixScreenOrigins[], - which the DDX layer must initialize in InitOutput(). The bounds - of the combined screen is also calculated (PanoramiXPixWidth and - PanoramiXPixHeight). - - - The DIX layer has a list of function pointers (ProcVector[]) - 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[]. 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. - - - PPaannoorraammiiXXCCoonnssoolliiddaattee(()) - PanoramiXConsolidate() is a device-independent extension - function that is called directly from the X server's main() - function after extensions and input/output devices have been - initialized, and before the root windows are defined and - initialized. - - - This function finds the set of depths (PanoramiXDepths[]) and - visuals (PanoramiXVisuals[]) common to all of the physical - screens. PanoramiXNumDepths is set to the number of common - depths, and PanoramiXNumVisuals is set to the number of common - visuals. Resources are created for the single root window and - the default colormap. Each of these resources has per-physical - screen entries. - - - PPaannoorraammiiXXCCrreeaatteeCCoonnnneeccttiioonnBBlloocckk(()) - PanoramiXConsolidate() is a device-independent extension - function that is called directly from the X server's main() - function after the per-physical screen root windows are created. - It is called instead of the standard DIX CreateConnectionBlock() - function. If this function returns FALSE, the X server exits - with a fatal error. This function will return FALSE if no - common depths were found in PanoramiXConsolidate(). With no - common depths, Xinerama mode is not possible. - - - 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 xdpyinfo shows). - The connection block is initialized with the combined single - screen values that were calculated in the above two functions. - - - 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(). - - - AA..33..11.. XXiinneerraammaa--ssppeecciiffiicc cchhaannggeess ttoo tthhee DDIIXX ccooddee - - There are a few types of Xinerama-specific changes within the DIX - code. The main ones are described here. - - - Functions that deal with colormap or GC -related operations outside of - the intercepted protocol requests have a test added to only do the - processing for screen numbers > 0. This is because they are handled - for the single Xinerama screen and the processing is done once for - screen 0. - - - 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. - - - 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. - - - AA..33..22.. XXiinneerraammaa--ssppeecciiffiicc cchhaannggeess ttoo tthhee MMII ccooddee - - The only Xinerama-specific change to the MI code is in - miSendExposures() to handle the coordinate (and window ID) translation - for expose events. - - - - AA..33..33.. IInntteerrcceepptteedd DDIIXX ccoorree rreeqquueessttss - - 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. - - - - BB.. DDeevveellooppmmeenntt RReessuullttss - - In this section the results of each phase of development are - discussed. This development took place between approximately June - 2001 and July 2003. - - - BB..11.. PPhhaassee II - - The initial development phase dealt with the basic implementation - including the bootstrap code, which used the shadow framebuffer, and - the unoptimized implementation, based on an Xnest-style - implementation. - - - BB..11..11.. SSccooppee - - The goal of Phase I is to provide fundamental functionality that can - act as a foundation for ongoing work: - - 1. Develop the proxy X server - - +o The proxy X server will operate on the X11 protocol and relay - requests as necessary to correctly perform the request. - - +o Work will be based on the existing work for Xinerama and Xnest. - - +o Input events and windowing operations are handled in the proxy - server and rendering requests are repackaged and sent to each of - the back-end servers for display. - - +o The multiple screen layout (including support for overlapping - screens) will be user configurable via a configuration file or - through the configuration tool. - - 2. Develop graphical configuration tool - - +o There will be potentially a large number of X servers to - configure into a single display. The tool will allow the user - to specify which servers are involved in the configuration and - how they should be laid out. - - 3. Pass the X Test Suite - - +o The X Test Suite covers the basic X11 operations. All tests - known to succeed must correctly operate in the distributed X - environment. - - - 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). - - - BB..11..22.. RReessuullttss - - 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. - - - 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. - - - 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. - - - 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 --ccoonnffiiggffiillee and --ccoonnffiigg command-line - options can be used to start Xdmx using a configuration file. - - - 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. - - - BB..11..33.. XX TTeesstt SSuuiittee - - BB..11..33..11.. IInnttrroodduuccttiioonn - - 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. - - 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. - - - BB..11..33..22.. EExxppeecctteedd FFaaiilluurreess ffoorr aa SSiinnggllee HHeeaadd - - 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: - - XDrawArc: Tests 42, 63, 66, 73 - XDrawArcs: Tests 45, 66, 69, 76 - - - - The following failures occur because of the high-level X server - implementation: - - XLoadQueryFont: Test 1 - XListFontsWithInfo: Tests 3, 4 - XQueryFont: Tests 1, 2 - - - - The following test fails when running the X server as root under Linux - because of the way directory modes are interpreted: - - XWriteBitmapFile: Test 3 - - - - 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. - - - BB..11..33..33.. EExxppeecctteedd FFaaiilluurreess ffoorr XXiinneerraammaa - - 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. - - 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. - - 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: - - These failures were noted with multiple Xinerama configurations: - - 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: - - XListPixmapFormats: Test 1 - XDrawRectangles: Test 45 - - - - These failures were noted only when using two video cards from - different vendors with a 4.1.99.x XFree86 server: - - XChangeWindowAttributes: Test 32 - XCreateWindow: Test 30 - XDrawLine: Test 22 - XFillArc: Test 22 - XChangeKeyboardControl: Tests 9, 10 - XRebindKeysym: Test 1 - - - - BB..11..33..44.. AAddddiittiioonnaall FFaaiilluurreess ffrroomm XXddmmxx - - 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: - - 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) - - - - 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. - - - BB..11..33..55.. SSuummmmaarryy aanndd FFuuttuurree WWoorrkk - - 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. - - 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. - - - - BB..11..44.. FFoonnttss - - 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 tthhee ffrroonntt-- aanndd bbaacckk--eenndd sseerrvveerrss mmuusstt sshhaarree tthhee eexxaacctt ssaammee ffoonntt - ppaatthh. There are two ways to help make sure that all servers share the - same font path: - - - 1. 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. - - 2. 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. - - - 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. - - - 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. - - - BB..11..55.. PPeerrffoorrmmaannccee - - 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. - - - 1. 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. - - 2. Sending drawing requests to only the screens that they overlap - should improve performance. - - - BB..11..66.. PPiixxmmaappss - - 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. - - - - BB..22.. PPhhaassee IIII - - The second phase of development concentrates on performance - optimizations. These optimizations are documented here, with x11perf - data to show how the optimizations improve performance. - - - 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. - - - BB..22..11.. MMoovviinngg ffrroomm XXFFrreeee8866 44..11..9999..11 ttoo 44..22..00..00 - - 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: - - 1.13 Fill 300x300 opaque stippled trapezoid (161x145 stipple) - 1.16 Fill 1x1 tiled trapezoid (161x145 tile) - 1.13 Fill 10x10 tiled trapezoid (161x145 tile) - 1.17 Fill 100x100 tiled trapezoid (161x145 tile) - 1.16 Fill 1x1 tiled trapezoid (216x208 tile) - 1.20 Fill 10x10 tiled trapezoid (216x208 tile) - 1.15 Fill 100x100 tiled trapezoid (216x208 tile) - 1.37 Circulate Unmapped window (200 kids) - - - - And the following tests were noted to be more than 10% slower: - - 0.88 Unmap window via parent (25 kids) - 0.75 Circulate Unmapped window (4 kids) - 0.79 Circulate Unmapped window (16 kids) - 0.80 Circulate Unmapped window (25 kids) - 0.82 Circulate Unmapped window (50 kids) - 0.85 Circulate Unmapped window (75 kids) - - - - These changes were not caused by any changes in the DMX system, and - may point to changes in the XFree86 tree or to tests that have more - "jitter" than most other x11perf tests. - - - BB..22..22.. GGlloobbaall cchhaannggeess - - During the development of the Phase II DMX server, several global - changes were made. These changes were also compared with the Phase I - server. The following tests were noted to be more than 10% faster: - - - - 1.13 Fill 300x300 opaque stippled trapezoid (161x145 stipple) - 1.15 Fill 1x1 tiled trapezoid (161x145 tile) - 1.13 Fill 10x10 tiled trapezoid (161x145 tile) - 1.17 Fill 100x100 tiled trapezoid (161x145 tile) - 1.16 Fill 1x1 tiled trapezoid (216x208 tile) - 1.19 Fill 10x10 tiled trapezoid (216x208 tile) - 1.15 Fill 100x100 tiled trapezoid (216x208 tile) - 1.15 Circulate Unmapped window (4 kids) - - - - The following tests were noted to be more than 10% slower: - - 0.69 Scroll 10x10 pixels - 0.68 Scroll 100x100 pixels - 0.68 Copy 10x10 from window to window - 0.68 Copy 100x100 from window to window - 0.76 Circulate Unmapped window (75 kids) - 0.83 Circulate Unmapped window (100 kids) - - - - For the remainder of this analysis, the baseline of comparison will be - the Phase II deliverable with all optimizations disabled (unless - otherwise noted). This will highlight how the optimizations in - isolation impact performance. - - - BB..22..33.. XXSSyynncc(()) BBaattcchhiinngg - - 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. - - - Out of more than 300 x11perf tests, 8 tests became more than 100 times - faster, with 68 more than 50X faster, 114 more than 10X faster, and - 181 more than 2X faster. See table below for summary. - - - The following tests were noted to be more than 10% slower with XSync() - batching on: - - 0.88 500x500 tiled rectangle (161x145 tile) - 0.89 Copy 500x500 from window to window - - - - BB..22..44.. OOffffssccrreeeenn OOppttiimmiizzaattiioonn - - 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. - - - Out of more than 300 x11perf tests, 3 tests were at least twice as - fast, and 146 tests were at least 10% faster. Two tests were more - than 10% slower with the offscreen optimization: - - 0.88 Hide/expose window via popup (4 kids) - 0.89 Resize unmapped window (75 kids) - - - - BB..22..55.. LLaazzyy WWiinnddooww CCrreeaattiioonn OOppttiimmiizzaattiioonn - - 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. - - - 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. - - - 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. - - - 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. - - - - 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. - - - This optimization improved the following x11perf tests by more than - 10%: - - 1.10 500x500 rectangle outline - 1.12 Fill 100x100 stippled trapezoid (161x145 stipple) - 1.20 Circulate Unmapped window (50 kids) - 1.19 Circulate Unmapped window (75 kids) - - - - BB..22..66.. SSuubbddiivviiddiinngg RReennddeerriinngg PPrriimmiittiivveess - - 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. - - - 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. - - - 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. - - - 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. - - - This optimization improved the following x11perf tests by more than - 10%: - - 1.12 Fill 100x100 stippled trapezoid (161x145 stipple) - 1.26 PutImage 10x10 square - 1.83 PutImage 100x100 square - 1.91 PutImage 500x500 square - 1.40 PutImage XY 10x10 square - 1.48 PutImage XY 100x100 square - 1.50 PutImage XY 500x500 square - 1.45 Circulate Unmapped window (75 kids) - 1.74 Circulate Unmapped window (100 kids) - - - - The following test was noted to be more than 10% slower with this - optimization: - - 0.88 10-pixel fill chord partial circle - - - - BB..22..77.. SSuummmmaarryy ooff xx1111ppeerrff DDaattaa - - With all of the optimizations on, 53 x11perf tests are more than 100X - faster than the unoptimized Phase II deliverable, with 69 more than - 50X faster, 73 more than 10X faster, and 199 more than twice as fast. - No tests were more than 10% slower than the unoptimized Phase II - deliverable. (Compared with the Phase I deliverable, only Circulate - Unmapped window (100 kids) was more than 10% slower than the Phase II - deliverable. As noted above, this test seems to have wider - variability than other x11perf tests.) - - - The following table summarizes relative x11perf test changes for all - optimizations individually and collectively. Note that some of the - optimizations have a synergistic effect when used together. - - - - 1: XSync() batching only - 2: Off screen optimizations only - 3: Window optimizations only - 4: Subdivprims only -

PPrrooffiilliinngg wwiitthh OOPPrrooffiillee - - 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 gprof, but without the necessity - of recompiling the program with special instrumentation (i.e., - OProfile can collect statistical profiling information about optimized - programs). A test harness was developed to collect OProfile data for - each x11perf test individually. - - - 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 gprof output. This - investigation has not produced results that yield performance - increases in x11perf numbers. - - - - BB..22..99.. XX TTeesstt SSuuiittee - - The X Test Suite was run on the fully optimized DMX server using the - configuration described above. The following failures were noted: - - XListPixmapFormats: Test 1 [1] - XChangeWindowAttributes: Test 32 [1] - XCreateWindow: Test 30 [1] - XFreeColors: Test 4 [3] - XCopyArea: Test 13, 17, 21, 25, 30 [2] - XCopyPlane: Test 11, 15, 27, 31 [2] - XSetFontPath: Test 4 [1] - XChangeKeyboardControl: Test 9, 10 [1] - - [1] Previously documented errors expected from the Xinerama - implementation (see Phase I discussion). - [2] Newly noted errors that have been verified as expected - behavior of the Xinerama implementation. - [3] Newly noted error that has been verified as a Xinerama - implementation bug. - - - - BB..33.. PPhhaassee IIIIII - - During the third phase of development, support was provided for the - following extensions: SHAPE, RENDER, XKEYBOARD, XInput. - - - BB..33..11.. SSHHAAPPEE - - 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. - - - BB..33..22.. RREENNDDEERR - - 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. - - - BB..33..33.. XXKKEEYYBBOOAARRDD - - 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. - - - BB..33..44.. XXIInnppuutt - - 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. - - - Currently, back-end extension devices are not available as Xdmx - extension devices, but this limitation should be removed in the - future. - - - To demonstrate the XInput extension, and to provide more examples for - low-level input device driver writers, USB device drivers have been - written for mice (usb-mou), keyboards (usb-kbd), and non-mouse/non- - keyboard USB devices (usb-oth). Please see the man page for - information on Linux kernel drivers that are required for using these - Xdmx drivers. - - - BB..33..55..

The API - for this support uses calls that are quite similar to XCreateWindow, - XPutImage, and XShmPutImage. Currently, most of the drivers - implemented in XFree86 only support data in various YUV formats. - However, several modern video adaptors support RGB as well. - Note, though, that the target output for this scaling is an overlay - plane -- so X Video provides functionality that is fundamentally - different from that provided by the Windows StrechBlt call. - - 33..

Because - of limited time available for this work, all of the edge cases were - not considered and the solution works well mainly for integer scaling. - - Currently, vncviewer writes to the X display with XPutImage, - XCopyArea, and XFillRectangle. All instances of these calls have to - be aware of scaling and must round correctly. In the prototype - solution, rounding is incorrect and can cause artifacts. - - A better solution would be to cache all updates to the desktop image - in vncviewer and only send the damaged area to the X display with - XPutImage. This would allow the damaged area to be computed so that - rounding errors do not create artifacts. This method is probably - similar to what is used in the Window client. (The whole VNC suite is - being re-written in C++ and the forthcoming version 4 has not been - evaluated.) - - 33..11..22.. SSccaalliinngg wwiitthh tthhee XX VViiddeeoo EExxtteennssiioonn - - The scaling in the Windows vncviewer application makes use of a scaled - blit that is supplied by the underlying system library. Several video - cards currently provide support for a scaled blit, and some X servers - (including XFree86) expose this capability to applications via the - XvPutImage interface of the X Video Extension. The capability exposed - by XvPutImage results in the scaled image being drawn to an overlay - plane. Most video cards also provide support for a scaled blit into - the normal output planes, but this is not exposed via XvPutImage. - - The vncviewer program could be modified to use the X Video Extension - to provide scaling under X11 that is similar to the scaling currently - provided under Windows. Unfortunately, Xdmx does not currently export - the X Video Extension, so this would not provide an immediate solution - usable with DMX. - - A very early-stage proof-of-concept prototype was implemented and a - preliminary patch against vnc-3.3.7-unixsrc is available in the - dmx/external directory. This prototype was implemented to better - understand the problems that must be solved to make this solution - viable: - - +o As noted under the software scaling section above, vncviewer writes - to the X display with several different calls. These calls write - to the normal output planes and are compatible with XvPutImage, - which writes to an overlay plane. To eliminate artifacts caused by - this problem, vncviewer should be modified so that a cached copy of - the desktop is available, either as a client-side image or a - server-side off-screen pixmap, so that XvPutImage would be the only - method for writing to the X display. - - +o - - Although several modern graphics adaptors support hardware scaling - using an RGB format (e.g., ATI Radeon, nVidia, etc.), XFree86 - drivers typically only implement YUV formats. YUV generally - compress the pixel information in some way. For example, two - commonly implemented formats, YUY2 and UYVY provide intensity - information for every RGB pixel, but only provide chroma and - luminance information for pairs of horizontal pixels. Since VNC - uses pixel-resolution for communicating updates on the wire, - additional artifacts are introduced (because there may not be - enough information from the wire to update a pair of pixels). - - Further, the well-known problem with YUV encoding is even more - evident when the image is a desktop instead of a movie. For - example, consider a 1-pixel-wide vertical window border. If the - border changes in color but not intensity (e.g., because a window - manager uses color to indicate focus), there may or may not be a - change in the YUY2 image, depending on the algorithm used for RGB - to YUV conversion and on how the border pixel is ordered in the - pair of pixels used by the algorithm. - - Many of these artifacts could be eliminated if vncviewer cached a - complete RGB image of the desktop, and only did the conversion to - YUV for properly aligned areas of damage. The remaining artifacts - could be eliminated if an RGB format was used with X Video (which - may require the extension of existing XFree86 drivers to support - RGB). - - +o Most modern video cards support exactly one overlay plane that is - suitable for use with X Video. Therefore, only one application can - use X Video at any given time. This is a severe limitation in a - desktop environment. - - 33..11..22..11.. IImmpplleemmeennttiinngg tthhee XX VViiddeeoo EExxtteennssiioonn ffoorr DDMMXX - - The user-level API for X Video is fairly simple, but the underlying - support required for the full specification is large. However, since - the API provides a method to query supported capabilities, a usable - subset of X Video can be implemented that would support XvPutImage and - little else. This would require support for the following: - - +o X Video Extension API calls, including the following: - - +o XvQueryExtension - - +o XvQueryAdaptors - - +o XvQueryPortAttributes - - +o XvFreeAdaptorInfo - - +o XvListImageFormats - - +o XvGrabPort - - +o XvCreateImage - - +o XvPutImage - - +o XvShmCreateImage - - +o XvShmPutImage - - +o Support for querying back-end X Video Extension capabilities. - - +o Support for sending the image to the back-ends. Because X Video - requires sending full images, there may be a trade-off between - bandwidth limitations and additional complexity to divide the image - up such that is scales properly. - - +o Possible support for a software fall-back. For example, if all of - the back-ends do not support the X Video Extension, software - scaling can be implemented such that the image is sent to the back- - end with XPutImage.

Discussion - of XPutImageScaled is deferred in favor of XCopyAreaScaled for the - following reasons: - - +o XPutImageScaled can be emulated with XCopyAreaScaled by first using - XPutImage to copy the image to an off-screen pixmap, and then - calling XCopyAreaScaled between that off-screen pixmap and the - target drawable. - - +o Since XCopyAreaScaled would copy between two areas of on-screen or - off-screen memory, it has additional uses and can be viewed as - efficiently providing a superset of XPutImageScaled functionality. - - 33..11..44.. SSccaalliinngg wwiitthh aann XXCCooppyyAArreeaaSSccaalleedd EExxtteennssiioonn - - As noted in the previous section, because XCopyAreaScaled provides a - superset of the functionality provided by XPutImageScaled, we will - consider this extension instead. - - First, XCopyAreaScaled would provide for RGB scaling between pixmaps - (i.e., on-screen or off-screen areas of memory that reside on the - video card). Unlike the X Video Extension, which writes into an - overlay plane, XCopyAreaScaled would write into the non-overlay areas - of the screen. Key points to consider are as follows: - - +o Because different planes are involved, the two scaling operations - are usually implemented in hardware differently, so an - XCopyAreaScaled extension could be added in a manner that would - neither conflict with nor interact with the X Video extension in - any way. - - +o The XCopyAreaScaled extension provides new functionality that the X - Video Extension does not provide. Based on anecdotal feedback, we - believe that many people outside the DMX and VNC communities would - be excited about this extension. - - +o The main drawback to this extension is that it is new and needs to - be implemented at the driver level in XFree86 for each video card - to be supported. At the present time, it is more likely that the X - Video Extension will be implemented for a particular piece hardware - because the X Video extension has multimedia uses. However, over - time, we would expect the XCopyAreaScaled extension to be - implemented along with the X Video extension, especially if it - becomes popular. - - +o Another drawback is that not all modern cards provide support for a - simple scaled blit operation. However, these cards usually do - provide a 3D pipeline which could be used to provide this - functionality in a manner that is transparent to the client - application that is using the XCopyAreaScaled extension. However, - this implementation pathway would make this extension somewhat more - difficult to implement on certain cards. - - 33..11..55.. SSccaalliinngg wwiitthh OOppeennGGLL - - Another general solution to the scaling problem is to use the texture - scaling found in all 3D hardware. This ability is already exposed - through OpenGL and can be exploited by clients without X server - modification (i.e., other than the ability to support OpenGL). An - application using OpenGL would transmit the non-scaled image to the X - server as a texture, and would then display a single non-transformed - rect using that texture. This also works around the single overlay - problem with the X Video Extension as well as the need to implement - additional scaled primitive extensions. - - The downside is that most OpenGL implementations require power of 2 - texture sizes and this can be very wasteful of memory if, for example, - the application needs to scale a 1025x1025 image, which would require - a 2048x2048 texture area (even a 640x480 image would require a - 1024x512 texture). Another downside is that some OpenGL - implementations have a limited about of texture memory and cannot - handle textures that are very large. For example, they might limit - the texture size to 1024x1024. - - 33..22.. AApppplliiccaattiioonn--ttrraannssppaarreenntt SSccaalliinngg ffoorr DDMMXX - - 33..22..11.. BBaacckk--eenndd SSccaalliinngg WWiitthhoouutt DDiissccoonnnneecctt//RReeccoonnnneecctt - - VNC does scaling on the client side (in the vncviewer application). - Implementing a similar solution for DMX would require support in the - back-end X servers and, therefore, is not a general solution. - - XFree86 already implements some support for "scaling" that could be - used with DMX: if, in the XF86Config file, multiple Modes are listed - in the Display Subsection of the Screen Section, then pressing Ctrl- - Alt-Plus and Ctrl-Alt-Minus can be used to iterate through the listed - modes. The display dimensions will change to the dimensions in the - Modes line, but the logical dimensions of the X server (i.e., the - dimensions that Xdmx knows about) will not change. - - Further, the dimensions of the XFree86 display are under software - control (via the XFree86-VidModeExtension), so the Xdmx server could - change the screen dimensions on a per-display basis, thereby scaling - the information on part of that display. - - However, this scaling appears to have limited use. For example, - assume a 4 by 4 display wall consisting of 16 1280x1024 displays. If - all of the back-end servers were simultaneously configured to display - 640x480, the left hand corner of each display would be magnified, but - the composite result would be unreadable. Magnifying one display at a - time could be usable, but could have limited utility, since the result - would still be no larger than a single display. - - - 33..22..22.. BBaacckk--eenndd SSccaalliinngg WWiitthh DDiissccoonnnneecctt//RReeccoonnnneecctt - - Disconnect and reconnect features are not currently supported in DMX, - but are scheduled to be implemented in the future. These features, - combined with the XFree86-VidModeExtension Extension, would allow an - application to do the following: - - +o Disconnect a specific back-end server (via the DMX Extension), - - +o reconfigure the XFree86 back-end server resolution, and - - +o reconnect the back-end server to DMX -- at a new origin with the - new screen resolution. - - For example, consider a display wall consisting of 16 1280x1024 - displays with a total resolution of 5120x4096. All of the screens - could be disconnected, repositioned, and reconnected each at a - resolution of 640x480. The total resolution of the display wall would - be 2560x1920, allowing a view of a selected area approximately one- - fourth of the size of the DMX display. This change would be - completely application independent (except, perhaps, for a DMX-aware - window manager). When work at the increased resolution was completed, - the back-end servers could be disconnected, reconfigured, and - reconnected for the original 5120x4096 view. - - Support for this type of scaling can be implemented in a DMX-aware X11 - client assuming the DMX server support arbitrary disconnect and - reconnect semantics. Because this application cannot be written - before disconnect/reconnect is implemented, this solution will not be - discussed further in this paper. - - 33..22..33.. SSeerrvveerr--ssiiddee SSccaalliinngg - - In earlier versions of DMX, a frame buffer was maintained on the - server side, and XPutImage was used to move the information from the - server to the client (similar to some early VNC implementations). The - use of a server-side frame buffer would allow the server to do - scaling, but is not a recommended solution because of overall - performance issues and server-side memory issues (i.e., the frame - buffer would be very large for large display walls). - - Exploration of this path is not recommended. - - 33..33.. XXCCrreeaatteeSSccaalleeddWWiinnddooww AAPPII - - The implementation of X Video Extension in DMX, and the use of - XvPutImage by applications requiring scaling requires significant - changes in DMX Further, XvPutImage is, essentially a scaled blit, and - it is only useful for applications which are already using (or can be - modified to use) XPutImage. Therefore, a more general API will be - discussed as another possibility. - - X applications typically create windows with the XCreateWindow call. - A new extension could provide an XCreateScaledWindow call that could - be used in place of the XCreateWindow call and be otherwise - transparent to the application. This would allow applications, even - those that do not depend on XPutImage, to take advantage of window - scaling. In this section we describe how the call would work, what - transparency it provides, and how to solve the potential problems that - transparency creates. - - 33..33..11.. XXCCrreeaatteeWWiinnddooww - - The XCreateWindow call takes width and height as parameters.

XXGGeettWWiinnddoowwAAttttrriibbuutteess,, XXGGeettGGeeoommeettrryy - - For transparency, calls that query the window attributes should return - unscaled information. This suggests that all unscaled pixmaps and - window attributes should be cached. - - Unfortunately, a window manager requires the scaled geometry to - properly decorate the window. The X server can probably determine - which client is acting as the window manager (e.g., because that - client will select events that are used exclusively by the window - manager). However, other Scaled Window Extension aware clients may - also need to determine the scaled geometry. Therefore, at least two - additional extension calls should be implemented: - XGetScaledWindowAttributes and XGetScaledGeometry. - - 33..33..44.. PPooppuupp aanndd CChhiilldd wwiinnddooww ppoossiittiioonnss - - Some applications may position popup and child windows based on an - unscaled notion of the main window geometry. In this case, additional - modifications to the client would be required. - - 33..33..55.. EEvveennttss - - Most events (e.g., for mouse motion) return information about the - coordinates at which the even occurred. These coordinates would have - to be modified so that unscaled values were presented to the client. - - 33..33..66.. IImmpplleemmeennttaattiioonn - - There are many implementation issues, some of which are similar to the - issues involved in implementing the X Video Extension for DMX. The - window contents must be scaled, either by performing all operations to - a frame buffer and then writing the image to the display (perhaps - using hardware scaling support), or by modifying all of the various - drawing operations to perform scaling. Because of the complexity - involved, the frame buffer option is recommended. - - 44.. CCoonncclluussiioonn aanndd RReeccoommmmeennddaattiioonnss - - We recommend a three phase implementation strategy, based on how an - application could be written to take advantage of scaling: - - 1. - - The XCopyAreaScaled extension should be implemented, since this is - the ideal solution for applications like VNC, and since making use - of this extension will require minimal changes to applications that - already use XPutImage or XCopyArea. - - The initial implementation work would include the design of the X - protocol extension, writing this up in the usual format for - extension documentation, implementation of the protocol transport - pieces in XFree86, implementation of a software fall-back in - XFree86 and DMX, one example hardware implementation for XFree86, - and implementation of support for this extension in DMX. - - We suggest implementing the extension first on the ATI Radeon - cards. However, since these cards do not provide a 2D scaled blit - primitive, the implementation would have to make use of the 3D - texture engine to emulate a scaled blit. This is recommended, - since other modern graphics cards also do not provide a simple 2D - scaled blit operation and an example of the more difficult - implementation pathway would be helpful to others. - - 2. - - Until XCopyAreaScaled is widely supported, applications that - require scaling will have to fall back to another scaling method. - We suggest OpenGL as the first fall-back method because it is - widely available and supported by DMX. - - A project centered around OpenGL-based scaling would implement this - scaling in VNC as an example. This work would include re-writing - the vncviewer rendering engine to cache a master copy of the - desktop image for all operations. - - 3. - - Since OpenGL is not implemented everywhere, and may not provide - hardware-assisted performance in every implementation, an - application that requires scaling should also fall back to using - the X Video Extension. - - This project would add support for the X Video Extension to DMX and - would add support to VNC to take advantage of this extension - without introducing artifacts. This would require modifying the - vncviewer rendering engine to cache a master copy of the desktop - image for all operations. This project should also add support for - the RGB format to at least one XFree86 driver (e.g., ATI Radeon). - - The X Video Extension is one of the few popular extensions that DMX - does not support. We recommend implementing the X Video Extension - even if scaling is the specific goal of that work. - - We do nnoott recommend implementation of the XCreateScaledWindow - extension because of the complexity involved. We do nnoott recommend - implementation of the XPutImageScaled extension because it requires - the same amount of work as the XCopyAreaScaled extension, but provides - less functionality. Further, server-side scaling with a large frame - buffer is nnoott recommended because of the performance implications. - - The back-end scaling, especially with disconnect/reconnect support - should be explored in the future after disconnect/reconnect is - implemented, but not at the present time. - - - diff --git a/xorg-server/hw/vfb/InitOutput.c b/xorg-server/hw/vfb/InitOutput.c index 60915fdbf..29857877e 100644 --- a/xorg-server/hw/vfb/InitOutput.c +++ b/xorg-server/hw/vfb/InitOutput.c @@ -77,7 +77,6 @@ from The Open Group. typedef struct { - int scrnum;
