drm/radeon: bump the UMS driver version number to indicate rv740 fix

2010-02-19T23:17:18+00:00

This lets UMS userspace know the rv740 fix is in. For KMS we can
consider the kernel release to be the v2.0.0 release so we don't need the
bump there.

drm/radeon/kms: free fence IB if it wasn't emited at IB free time

2010-02-19T21:35:18+00:00

If at IB free time fence wasn't emited that means the IB wasn't
scheduled because an error occured somewhere, thus we can free
then fence and mark the IB as free.

drm/radeon/rv740: fix backend setup

2010-02-19T21:28:16+00:00

This patch fixes occlusion queries and rendering errors
on rv740 boards. Hardcoding the backend map is not an optimal
solution, but a better fix is being worked on.

drm/radeon/kms: fix bo's fence association

2010-02-18T05:07:04+00:00

Previous code did associate fence to bo before the fence was emited
and it also didn't lock protected access to ttm sync_obj member.
Both of this flaw leads to possible race between different code
path. This patch fix this by associating fence only once the fence
is emitted and properly lock protect access to sync_obj member of
ttm.

drm/radeon/kms: fix indirect buffer management V2

2010-02-18T05:06:41+00:00

There is 3 different distinct states for an indirect buffer (IB) :
  1- free with no fence
  2- free with a fence
  3- non free (fence doesn't matter)
Previous code mixed case 2 & 3 in a single one leading to possible
catastrophique failure. This patch rework the handling and properly
separate each case. So when you get ib we set the ib as non free and
fence status doesn't matter. Fence become active (ie has a meaning
for the ib code) once the ib is scheduled or free. This patch also
get rid of the alloc bitmap as it was overkill, we know go through
IB pool list like in a ring buffer as the oldest IB is the first
one the will be free.

Fix :
https://bugs.freedesktop.org/show_bug.cgi?id=26438
and likely other bugs.

V2 remove the scheduled list, it's useless now, fix free ib scanning

drm/radeon/kms: use udelay for short delays

2010-02-18T05:00:08+00:00

For usec delays use udelay instead of scheduling, this should
allow reclocking to happen faster. This also was the cause
of reported 33s delays at bootup on certain systems.

drm/radeon/kms: make sure retry count increases.

2010-02-15T05:24:48+00:00

In testing I've never seen it go past 1 retry anyways but better
safe than sorry.
