- Generic Rootless Layer
- Version 1.0

-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:
-
- OP {
- GC_SAVE(gc);
- GCOP_UNWRAP(gc);
-
- ...
-
- if (canAccelxxx(..) && otherwise-suitable)
- GC_UNSET_PM(gc, dst);
