Dave Airlie 25c51f539f drm/ttm: ioctl cleanup for buffer object - user side only
This just cleans up the xf86drm.c to what I want and drm.h,
I need to fix up the kernel internals to suit these changes now.

I've moved to using struct instead of typedefs for the bo and it doesn't look
that bad so I'll do the same thing for mm and fence..

2007-02-02 14:47:44 +01:00
Thomas Hellstrom 3024f23c65 memory manager: Make device driver aware of different memory types.
Memory types are either fixed (on-card or pre-bound AGP) or not fixed
(dynamically bound) to an aperture. They also carry information about:

1) Whether they can be mapped cached.
2) Whether they are at all mappable.
3) Whether they need an ioremap to be accessible from kernel space.

In this way VRAM memory and, for example, pre-bound AGP appear
identical to the memory manager.

This also makes support for unmappable VRAM simple to implement.

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.

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.
2006-10-11 13:40:35 +02:00
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.
