Update to DRM CVS as of 2005-04-12, bringing many changes:
- Split core DRM routines back into their own module, rather than using the
nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
testbox). Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
to the drmsub device. Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work. Covers the
Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.

Update to DRM CVS as of 2005-04-12, bringing many changes:
- Split core DRM routines back into their own module, rather than using the
nasty templated system like before.
- Development-class R300 support in radeon driver (requires userland pieces, of
course).
- Mach64 driver (haven't tested in a while -- my mach64s no longer fit in the
testbox). Covers Rage Pros, Rage Mobility P/M, Rage XL, and some others.
- i915 driver files, which just need to get drm_drv.c fixed to allow attachment
to the drmsub device. Covers i830 through i915 integrated graphics.
- savage driver files, which should require minimal changes to work. Covers the
Savage3D, Savage IX/MX, Savage 4, ProSavage.
- Support for color and texture tiling and HyperZ features of Radeon.
