These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
The pixman headers have been located under pixman-1/ instead of pixman/ since
around 2007-08-06, and pixman-1.pc has the updated include paths to account
for this.
This reverts commit feb1b3e455.
Don't call fbFinishWrap until the pixman_image_t that stores the pointer is
actually freed. This prevents corruption or crashes caused by accessing a
wrapped pointer after the wrapping is torn down.
Use the READ and WRITE macros to wrap memory accesses that could be in video
memory. Add MEMCPY_WRAPPED and MEMSET_WRAPPED macros to wrap memcpy and
memset, respectively.
Pass the size of the data pointed to by src or dst as an argument to
wfb{Read,Write}Memory. This allows one set of macros to be used with any size
pointer. Assumes that sizeof(FbBits) >= sizeof(FbStip).
Create fbPrepareAccess macros to call into the driver to set up the
wfbReadMemory and wfbWriteWemory pointers. Call these from fbGetDrawable and
fbGetStipDrawable.
Add the READ and WRITE macros, which expand to simple memory accesses for fb,
and calls through the function pointers for wfb.
Add fbFinishAccess macro to give the driver an opportunity to clean up. Add
calls to this in the appropriate places.
For now, just #define all of the exported symbols in wfbrename.h. Later,
we should add FBPREFIX() around the exported symbols and use -fvisiblity=hidden
to hide the rest.
Builds fb/* twice, defining FB_ACCESS_WRAPPER for libwfb.la. Define a macro,
FBPREFIX(X) which expands to fbX for libfb.la and wfbX for libwfb.la. Use the
macro on [w]fbModuleData so the new module loads.
- Merge various fb/ bits of COMPOSITE support from xserver, which weren't
necessary before due to cw hiding the issues. Fixes offset calculations
for a number of operations, and may pull some fixes that cairo has
wanted for XAA as well.
- Add a new call, miDisableCompositeWrapper(), which a DDX can call to keep
cw from getting initialized from the damage code. While it would be
cleaner to have each DDX initialize it if it needs it, we don't have
control over all of them (e.g. nvidia).
- Use the miDisableCompositeWrapper() to keep cw from getting set up for
screens using EXA, because EXA is already aware of composite. Avoiding
cw improved performance 0-35% on operations tested by ajax in x11perf.
Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.
framebuffer formats except cfb and the overlay modes should work, and
r128 and radeon need to be loaded from the ati driver (both issues to
be fixed soon). Tested on i740, s3virge, mach64, tdfx, vesa, and vga
drivers. elfloader users shouldn't be affected.

- Change #ifdef for checking for old format miScreenInit to
FB_OLD_MISCREENINIT for easier portability to xservers with updated
screen structs but old function prototypes. Make it automatically
defined if FB_OLD_SCREEN is defined.
- Add _LP64 to list of #ifdefs for 64-bit platforms to support
64-bit Solaris.
