17a6d97402 Make drm(4) build, if not work reliably, on PowerPC. 2010-11-16 03:43:06 +00:00

9c03c0d88c Rework how drm maps are handled. 
* 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.

f588a0bda5 Add kernel support for Radeon R6/7xx 3D. 
You will still need Mesa from git and possibly an updated DDX driver,
but this is working fairly well now.
