Lyons + torrey@xfree86.org + + +Introduction + + The generic rootless layer allows an X server to be implemented +on top of another window server in a cooperative manner. This allows the +X11 windows and native windows of the underlying window server to +coexist on the same screen. The layer is called "rootless" because the root +window of the X server is generally not drawn. Instead, each top-level +child of the root window is represented as a separate on-screen window by +the underlying window server. The layer is referred to as "generic" +because it abstracts away the details of the underlying window system and +contains code that is useful for any rootless X server. The code for the +generic rootless layer is located in xc/programs/Xserver/miext/rootless. To +build a complete rootless X server requires a specific rootless +implementation, which provides functions that allow the generic rootless +layer to interact with the underlying window system. + + +Concepts + + In the context of a rootless X server the term window is used to +mean many fundamentally different things. For X11 a window is a DDX +resource that describes a visible, or potentially visible, rectangle on the +screen. A top-level window is a direct child of the root window. To avoid +confusion, an on-screen native window of the underlying window system +is referred to as a "frame". The generic rootless layer associates each +mapped top-level X11 window with a frame. An X11 window may be said +to be "framed" if it or its top-level parent is represented by a frame. + + The generic rootless layer models each frame as being backed at +all times by a backing buffer, which is periodically flushed to the screen. +If the underlying window system does not provide a backing buffer for +frames, this must be done by the rootless implementation. The generic +rootless layer model does not assume it always has access to the frames' +backing buffers. Any drawing to the buffer will be proceeded by a call to +the rootless implementation's StartDrawing() function and StopDrawing() +will be called when the drawing is concluded. The address of the frame's +backing buffer is returned by the StartDrawing() function and it can +change between successive calls. + + Because each frame is assumed to have a backing buffer, the +generic rootless layer will stop Expose events being generated when the +regions of visibility of a frame change on screen. This is similar to backing +store, but backing buffers are different in that they always store a copy of +the entire window contents, not just the obscured portions. The price paid +in increased memory consumption is made up by the greatly decreased +complexity in not having to track and record regions as they are obscured. + + +Rootless Implementation + + The specifics of the underlying window system are provided to the +generic rootless layer through rootless implementation functions, compile- +time options, and runtime parameters. The rootless implementation +functions are a list of functions that allow the generic rootless layer to +perform operations such as creating, destroying, moving, and resizing +frames. Some of the implementation functions are optional. A detailed +description of the rootless implementation functions is provided in +Appendix A. + + By design, a rootless implementation should only have to include +the rootless.h header file. The rootlessCommon.h file contains definitions +internal to the generic rootless layer. (If you find you need to use +rootlessCommon.h in your implementation, let the generic rootless layer +maintainers know. This could be an area where the generic rootless layer +should be generalized.) A rootless implementation should also modify +rootlessConfig.h to specify compile time options for its platform. + + The following compile-time options are defined in +rootlessConfig.h: + + o ROOTLESS_ACCEL: If true, use the optional rootless acceleration + functions where possible to a accelerate X11 drawing primitives. + If false, all drawing will be done with fb. + + o ROOTLESS_GLOBAL_COORDS: This option controls the way that frame + coordinates are passed to the rootless implementation. If false, + the coordinates are passed per screen relative to the origin of + the screen the frame is currently on. Some implementations may + prefer to work in a single global coordinate space that spans all + screens. If this option is true, the coordinates are passed after + adding the coordinates of the screen origin and an overall offset of + (rootlessGlobalOffsetX, rootlessGlobalOffsetY). + + o ROOTLESS_PROTECT_ALPHA: By default for a color bit depth of 24 and + 32 bits per pixel, fb will overwrite the "unused" 8 bits to optimize + drawing speed. If this is true, the alpha channel of frames is + protected and is not modified when drawing to them. The bits + containing the alpha channel are defined by the macro + RootlessAlphaMask(bpp), which should return a bit mask for + various bits per pixel. + + o ROOTLESS_REDISPLAY_DELAY: Time in milliseconds between updates to + the underlying window server. Most operations will be buffered until + this time has expired. + + o ROOTLESS_RESIZE_GRAVITY: If the underlying window system supports it, + some frame resizes can be optimized by relying on the frame contents + maintaining a particular gravity during the resize. In this way less + of the frame contents need to be preserved by the generic rootless + layer. If true, the generic rootless layer will pass gravity hints + during resizing and rely on the frame contents being preserved + accordingly. + + o ROOTLESS_TRACK_DAMAGE: The generic rootless layer draws to the + frames' backing buffers and periodically flushes the modified + regions to the underlying window server. If this option is true, + the generic rootless layer will track these damaged regions. + Currently it uses the miRegion code and will not simplify damaged + regions even when updating a bounding region would be more + efficient. Some window systems provide a more efficient way to + track damaged regions. If this option is false, the rootless + implementation function DamageRects() is called whenever a + backing buffer is modified and the rootless implementation is + expected to track the damaged regions itself. + + The following runtime options are defined in rootless.h: + + o rootlessGlobalOffsetX, rootlessGlobalOffsetY: These are only + used if ROOTLESS_GLOBAL_COORDS is true. They specify the global + offset that is applied to all screens when converting from + screen-local to global coordinates. + + o rootless_CopyBytes_threshold, rootless_FillBytes_threshold, + rootless_CompositePixels_threshold, rootless_CopyWindow_threshold: + The minimum number of bytes or pixels for which to use the rootless + implementation's respective acceleration function. The rootless + acceleration functions are all optional so these will only be used + if the respective acceleration function pointer is not NULL. + + +Accelerated Drawing + + The rootless implementation typically does not have direct access +to the hardware. Its access to the graphics hardware is generally through +the API of the underlying window system. This underlying API may not +overlap well with the X11 drawing primitives. The generic rootless layer +falls back to using fb for all its 2-D drawing. Providing optional rootless +implementation acceleration functions can accelerate some graphics +primitives and some window functions. Typically calling through to the +underlying window systems API will not speed up these operations for +small enough areas. The rootless_*_threshold runtime options allow the +rootless implementation to provide hints for when the acceleration +functions should be used instead of fb. + + +Alpha Channel Protection + + If the bits per pixel is greater then the color bit depth, the contents +of the extra bits are undefined by the X11 protocol. Some window systems +will use these extra bits as an alpha channel. The generic rootless layer can +be configured to protect these bits and make sure they are not modified by +other parts of the X server. To protect the alpha channel +ROOTLESS_PROTECT_ALPHA and RootlessAlphaMask(bpp) must be +set appropriately as described under the compile time options. This +ensures that the X11 graphics primitives do not overwrite the alpha +channel in an attempt to optimize drawing. In addition, the window +functions PaintWindow() and Composite() must be replaced by alpha +channel safe variants. These are provided in rootless/safeAlpha. + + +Credits + + The generic rootless layer was originally conceived and developed +by Greg Parker as part of the XDarwin X server on Mac OS X. John +Harper made later optimizations to this code but removed its generic +independence of the underlying window system. Torrey T. Lyons +reintroduced the generic abstractions and made the rootless code suitable +for use by other X servers. + + +Appendix A: Rootless Implementation Functions + + The rootless implementation functions are defined in rootless.h. It +is intended that rootless.h contains the complete interface that is needed by +rootless implementations. The definitions contained in rootlessCommon.h +are intended for internal use by the generic rootless layer and are more +likely to change. + + Most of these functions take a RootlessFrameID as a parameter. +The RootlessFrameID is an opaque object that is returned by the +implementation's CreateFrame() function. The generic rootless layer does +not use this frame id other than to pass it back to the rootless +implementation to indicate the frame to operate on. + +/* + * Create a new frame. + * The frame is created unmapped. + * + * pFrame RootlessWindowPtr for this frame should be completely + * initialized before calling except for pFrame->wid, which + * is set by this function. + * pScreen Screen on which to place the new frame + * newX, newY Position of the frame.

These are + controlled with ROOTLESS_PROTECT_ALPHA and ROOTLESS_ACCEL. + + If ROOTLESS_PROTECT_ALPHA is set, we have to make sure that the alpha + channel of the on screen windows is always opaque. fb makes this harder + than it would otherwise be by noticing that a planemask of 0x00ffffff + includes all bits when depth==24, and so it "optimizes" the planemask to + 0xffffffff. We work around this by temporarily setting depth=bpp while + changing the GC. + + So the normal situation (in 32 bit mode) is that the planemask is + 0x00ffffff and thus fb leaves the alpha channel alone. The rootless + implementation is responsible for setting the alpha channel opaque + initially. + + Unfortunately drawing with a planemask that doesn't have all bits set + normally causes fb to fall off its fastest paths when blitting and + filling. So we try to recognize when we can relax the planemask back to + 0xffffffff, and do that for the duration of the drawing operation, + setting the alpha channel in fg/bg pixels to opaque at the same time. We + can do this when drawing op is GXcopy. We can also do this when copying + from another window since its alpha channel must also be opaque. + + The other issue to consider is that the rootless implementation may + provide accelerated drawing functions if ROOTLESS_ACCEL is set. For some + drawing primitives we swap in rootless acceleration functions, which use + the accelerated drawing functions where possible. + + Where both alpha protection and acceleration is used, it is even a bigger + win to relax the planemask to all ones because most accelerated drawing + functions can only be used in this case. However, even if we can't set + the planemask to all ones, we can still use the accelerated + CompositePixels function for GXcopy if it is a forward copy. This is + mainly intended for copying from pixmaps to windows. The CompositePixels + operation used sets alpha to 0xFF during the copy. + + The three macros below are used to implement this, potentially accelerated + drawing ops look something like this: + + OP { + GC_SAVE(gc);
