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.
available, with fbdev being used by default.
- Use depth 16 by default when vesa backend is used.
- Add MMIO defines for PowerPC (should be in a common location).
Many thanks for Michel Daenzer for much of this code.
help with ati, and future DRM drivers.
- Add new "ati" kdrive driver. It has ancestry in the r128 driver from
andersca, but took a detour through being the WIP SiS 300 driver on the
way. It supports Radeons (tested on QD VIVO and 7500) and Rage 128.
Current limitations include that it requires depth 16 and that the
other Rage 128 PCI IDs aren't included yet.
