been decided that the priority is to preserve the server's internal
API/ABI so that third-party drivers that depend on symbols like
noPanoramiXExtension, etc., would not need to be recompiled. Too bad
gcc on Linux doesn't support ELF's weak symbols as that would have been
a reasonable solution for preserving the ABI. N.B.: While symbols, i.e.
functions and variables revert to the old name, I did not revert build
names, i.e. -DXINERAMA, to the old -DPANORAMIX. There was no need, and
it's just a build issue that has no impact on the binary output of the
build.
- Reserve areas for back/depth/span when USING_DRI && GLXEXT. This would be
better in a TransitionTo3d, but we'd need to work with the offscreen
memory manager for that.
- Misc. fixes to ati_dri.c for DRI+GLX. Needs more work still.
limit on offscreen memory in the fbdev case. I remember daenzer (who
originally put that code in) saying he wasn't sure of it, and there
doesn't seem to be any reason for that limit given how acceleration is
done.
pixmap into temporary offscreen storage. Subsequent UploadToScratch may
clobber the data of previous ones. This allows hardware acceleration of
composite operations on glyphs.
- Add a new UploadToScreen kaa hook for doing the actual moving of data to
framebuffer. This would allow us to do things like hostdata blits or
memcpy to agp and then blit.
- Add an UploadToScreen on ATI which is just memcpy, but which will be
replaced with a hostdata blit soon.
- Add UploadToScratch on ATI and reserve 64k of scratch space. This
provided a 3x speedup of rgb24text on my Radeon.
emitting as a tri fan rather than a tri list. A rect list would save an
additional vertex (out of 4) per rectangle, but there's no measurable
speed difference and the tri fan may be useful when transforms come
into play.
accel. I don't 100% trust that the math works for Saturate, but I can't
tell from existing information.
- Fix texture pitch fallback checks.
- Fallback when src or mask have transforms.
- Disable Radeon Composite accel until the offset thing is fixed.
- Set offscreenPitch to 64 on Radeon thanks to new information and a kaa
fix. Fixes acceleration at width!=1024.
functions. Along with making things more readable, it fixes a problem
where the coordinates would get messed up if acceleration failed due to
things like pixmaps being in the wrong locations.
pixmaps are offscreen and don't have alpha maps. It is the last case
checked before going to software fallback
- Use the new Composite hook in the ati driver to implement acceleration of
most Composites that get done in an xcompmgr environment on r100 series
cards. It is only available when using the DRM. There are still some
corruption issues, but the DRI is still non-default and I need to get
this into version control.
- Add libdrm and libdri. Portions of the DRI extension are stubbed out.
- Use the DRM in the ATI driver when available. This provides a minor
performance improvement in x11perf, and opens the possibility of using
the 3d hardware for acceleration in the future.
- Implement solid fill acceleration for Composite in KAA.
- Implement Blend hook for Composite and use it on r128.
- Fix a bug of mine that resulted in overuse of offscreen memory.
- Fix many miscellaneous bugs in ATI driver and add PCI IDs.
