           Summary: [r300g] Wine d3d9 tests hardlock
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: drakkk@centrum.cz


When running d3d9 tests from Wine-1.2-rc7 it lock up my computer. Surprisingly
it works with r300c but I suppose some tests are being skipped because r300c
doesn't advertise as much as r300g. I don't know how to obtain more debug info,
since its completely dead and I'm not even able to ssh in.  

wine: 1.2-rc7
GPU: rv530
mesa: cd629c28d73703a44f4b74ba0e8eb87c51eee32a
kernel: 2.6.33.6-147.fc13

Does it help if you go before the commit

I've committed some fixes, is it any better now?

Hm, it helps a little bit...
With mesa 0864851e2763291ff1ea2ceaa3c6f16b14abd362 it doesn't hardlock, just X
is frozen. This is probably different test which is failing now. Not sure if it
fails earlier or later, but when it freezes the test picture is different that
when it hardlocks. 

dmesg is full of: 
[drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
[drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(0).
[drm:radeon_cs_ioctl] *ERROR* Faild to schedule IB !
[drm:radeon_ib_schedule] *ERROR* radeon: couldn't schedule IB(1).
...
repeating with numbers from 0 to 15.

Attaching whole terminal output, there are many failed tests, probably many
other problems, some of them may be a wine issue, but they should just fail not
take system or X down with them...

No

I think the problem is r300g doesn't currently support multiple rendering
contexts.

Have those tests ever worked? If yes, could you bisect this regression?

I don't know, I run them today for a first time. However quick testing showed
that it doesn't work with b939f83eb7af8f818c638453b2d2522b2362a831 (10 days
old) and 9be40de0871980ca541f0682aef6c1c507c1610f (month old) so probably not a
regression. I'll try to ask tomorrow some Wine people how to find out which
exact test is failing and what is it supposed to do.

Multiple simultaneously running contexts are most probably the cause of these
hardlocks, because this way the driver may generate pretty much a random
command stream which has valid register writes, meaning that the CS checker
doesn't notice anything, and the hardware goes crazy.

Wine uses multiple contexts quite often, if not all the time.

Soon I am going to rewrite winsys for it to support multiple command streams,
and then we'll see if it resolves this issue...

Pushed the multi-context stuff.

The only test which currently locks up is d3d9/visual/pointsize_test/the second
subtest.
