Xorg.0.log

This happened early May on drm-next somewhere between 4f256e8..d3029b4,
and is still there in 3.5rc3 (and in current drm-next).

Things are smeared out vertically. Looks like desktop background is not
corrupted. By turning off "EXABitmaps" there is less corruption.

I haven't done git bisecting, only download bisecting from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/ and
v3.4-rc6-295-g4f256e8 from May 8th was good and v3.4-rc6-315-gd3029b4
from May 10th was bad. Unfortunately the build from May 9th has been
deleted in the meantime so I can not narrow it down further this way. So
the commits in question should be:

d3029b4 drm/radeon/kms: fix warning on 32-bit in atomic fence printing
f2e3922 drm/radeon: make the ib an inline object
f237750 drm/radeon: remove r600 blit mutex v2
68470ae drm/radeon: move the semaphore from the fence into the ib
7c0d409 drm/radeon: immediately free ttm-move semaphore
c507f7e drm/radeon: rip out the ib pool
a8c0594 drm/radeon: simplify semaphore handling v2
c3b7fe8 drm/radeon: multiple ring allocator v3
0085c950 drm/radeon: use one wait queue for all rings add fence_wait_any v2
557017a drm/radeon: define new SA interface v3
2e0d991 drm/radeon: make sa bo a stand alone object
e6661a9 drm/radeon: keep start and end offset in the SA
711a972 drm/radeon: add sub allocator debugfs file
a651c55 drm/radeon: add proper locking to the SA v3
dd8bea2 drm/radeon: use inline functions to calc sa_bo addr
8a47cc9 drm/radeon: rework locking ring emission mutex in fence deadlock 
detection v2
3b7a2b2 drm/radeon: rework fence handling, drop fence list v7
bb63556 drm/radeon: convert fence to uint64_t v4
d6999bc drm/radeon: replace the per ring mutex with a global one
133f4cb drm/radeon: fix possible lack of synchronization btw ttm and other ring

Can you try to bisect this using git bisect and find the first bad

Sorry, I don't know when I can have time to do that. I'll try harder if
the bug can be confirmed by other people too. Maybe the right developer
can make an educated guess if it's limited to this card.

Hi guys,

can this be related to

?

I ended up in the same area of the git log.

backport of Christian's patch

I tried backporting Christian's patch from
https://bugs.freedesktop.org/show_bug.cgi?id=54129#c11 but it did not
help either. I suppose the following
/sys/kernel/debug/dri/0/radeon_fence_info output indicates that the
patch took effect, since the emitted numbers are above 0x100000000LL?

--- ring 0 ---
Last signaled fence 0x000000020000149f
Last emitted  0x0000000100001a9a

--- ring 0 ---
Last signaled fence 0x000000020000149f
Last emitted  0x0000000100002041

--- ring 0 ---

WTF? Well that's a very interesting information you've got us here,
thanks allot.

"deadbeef" is a pattern we usually use for ring and IB tests, and I have
no idea how that ended up as last signaled fence value.

Could you try Jeromes debugging patch
(http://people.freedesktop.org/~glisse/0001-debug-fence-emission-
reception.patch) and attach the resulting output.

Thx,
Christian.

Please give the attached V3 version of the patch a try, it adds the last
emitted fence as an upper limit and so should be able to even handle
"deadbeef" values.

Cheers,
Christian.

Yes, v3 works! I applied it to 3.5.2 by replacing
rdev->fence_drv[ring].sync_seq[ring] with rdev->fence_drv[ring].seq and
there is no more corruption. The
/sys/kernel/debug/dri/0/radeon_fence_info is now in sync, or off by one:

--- ring 0 ---
Last signaled fence 0x0000000000002651
Last emitted  0x0000000000002652
--- ring 0 ---
Last signaled fence 0x0000000000002703
Last emitted  0x0000000000002704

Do you still want me to run the debug patch? It seems you are not sure
about the 0xdeadbeef and there could be other bugs?
