drm/radeon/kms: Silent spurious error message

2010-10-12T10:18:07+00:00

I see the following error message in my kernel log from time to time:
radeon 0000:07:00.0: ffff88007c334000 reserve failed for wait
radeon 0000:07:00.0: ffff88007c334000 reserve failed for wait

After investigation, it turns out that there's nothing to be afraid of
and everything works as intended. So remove the spurious log message.

drm/radeon/kms: leave certain CP int bits enabled

2010-10-12T10:18:04+00:00

These bits are used for internal communication and should
be left enabled.  This may fix s/r issues on some systems.

drm/radeon/kms: avoid corner case issue with unmappable vram V2

2010-10-12T10:17:43+00:00

We should not allocate any object into unmappable vram if we
have no means to access them which on all GPU means having the
CP running and on newer GPU having the blit utility working.

This patch limit the vram allocation to visible vram until
we have acceleration up and running.

Note that it's more than unlikely that we run into any issue
related to that as when acceleration is not woring userspace
should allocate any object in vram beside front buffer which
should fit in visible vram.

V2 use real_vram_size as mc_vram_size could be bigger than
   the actual amount of vram

drm/i915: Prevent module unload to avoid random memory corruption

2010-10-08T13:11:00+00:00

The i915 driver has quite a few module unload bugs, the known ones at
least have fixes that are targeting 2.6.37. However, in order to
maintain a stable kernel, we should prevent this known random memory
corruption following driver unload. This should have very low impact on
normal users who are unlikely to need to unload the i915 driver.

drm: don't drop handle reference on unload

2010-10-07T04:01:17+00:00

since the handle references are all tied to a file_priv, and when it disappears
all the handle refs go with it.

The fbcon ones we'd only notice on unload, but the nouveau notifier one
would would happen on reboot.

drm/ttm: Fix two race conditions + fix busy codepaths

2010-10-05T23:04:43+00:00

This fixes a race pointed out by Dave Airlie where we don't take a buffer
object about to be destroyed off the LRU lists properly. It also fixes a rare
case where a buffer object could be destroyed in the middle of an
accelerated eviction.

The patch also adds a utility function that can be used to prematurely
release GPU memory space usage of an object waiting to be destroyed.
For example during eviction or swapout.

The above mentioned commit didn't queue the buffer on the delayed destroy
list under some rare circumstances. It also didn't completely honor the
remove_all parameter.
