Robert Noland	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.	2010-04-22 18:21:25 +00:00

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.

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.
