+ Generic Rootless Layer
+ Version 1.0
+ July 13, 2004

+
+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.

+ There are two issues we must contend with when drawing. 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:
