Thomas Hellstrom 10150df02b Simplify the AGP backend interface somewhat.
Fix buffer bound caching policy changing, Allow
on-the-fly changing of caching policy on bound buffers if the hardware
supports it.

Allow drivers to use driver-specific AGP memory types for TTM AGP pages.
Will make AGP drivers much easier to migrate.

Thomas Hellstrom 3070389367 Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is that
it will go away in the mainstream kernel.
Some bugfixes, mainly in error paths.
2006-10-11 22:21:01 +02:00
Thomas Hellstrom f2db76e2f2 Big update:
Adapt for new functions in the 2.6.19 kernel.
Remove the ability to have multiple regions in one TTM.
   This simplifies a lot of code.
Remove the ability to access TTMs from user space.
   We don't need it anymore without ttm regions.
Don't change caching policy for evicted buffers. Instead change it only
   when the buffer is accessed by the CPU (on the first page fault).
   This tremendously speeds up eviction rates.
Current code is safe for kernels <= 2.6.14.
Should also be OK with 2.6.19 and above.

Thomas Hellstrom 3802f9adbf Fix buffer manager takedown error.
Prepare for the possibility to evict all buffers from vram / agp.
This will be used by the X server when, for example, switching vts.

2006-09-18 20:43:31 +02:00
Thomas Hellstrom f613022cee Allow a "native type" to be associated with a fence sequence.
In the intel case, we can associate a flush with a sequence.

Thomas Hellstrom 49fbeb339c Some bugfixes.
Change the fence object interface somewhat to allow some more flexibility.
