* Rework how drm maps are handled.rnoland2010-04-221-1/+1
| | | | | | | | | | | | * On 32 bit platforms we steal the upper 4 bits of the map handle to store a unique map id. * On 64 bit platforms we steal the upper 24 bits. Resolves issues where the offsets that are handed to mmap may overlap the VRAM on some cards. Tested on: radeon, intel, mga, and via. This will break nouveau. I will spin new patches shortly.
* Welcome drm support for VIA unichrome chips.rnoland2010-01-311-0/+137
