Bug ID: 94511 Summary: rv730 agp reproducable uvd gpu hangs in fullscreen Product: Mesa Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: roman.elshin@gmail.com QA Contact: dri-devel@lists.freedesktop.org

With some movies gpu hangs are quite reproducable while playing with "mpv hwdec=vdpau vo=vdpau" in fullscreen (1920x1200), in the same time "mpv hwdec=vdpau vo=opengl" work fine there. For me it is quite easy to reproduce this with such encoded video: ffmpeg -i big_buck_bunny_1080p_surround.avi -vf scale=1024:576 -c:v libx264 -preset medium -x264-params keyint_min=23 -c:a copy output_1024_576.mkv Mostly it requires less then one minutes of playing in full screen for GPU hangs. I suppose that problem is rv730 specific, as I can not reproduce it with rv740 (but it PCIe and work with CPU which is mutch faster).

--- Comment #3 from Christian König deathsimple@vodafone.de --- Most likely the name of the problem here is AGP.
We already tried a couple of different workarounds but it is quite hard to get fully stable with UVD.
Try to disable AGP with radeon.agpmode=-1 and see if that helps.

--- Comment #4 from Roman Elshin roman.elshin@gmail.com --- No it does not change it, I think it more likely size alignments related issue. If I change monitors video mode to 1366x768 (16/9 same as video 1024/576) it works in fullscreen too. More clearly would be a 1920x1080, but I was unable to set cvt 1920 1080 60 mode (screen corruption).

--- Comment #5 from Christian König deathsimple@vodafone.de --- Ok, well that's a bit strange.
Does "mpv vo=vdpau" works? E.g. VDPAU output, but with software decoding?

--- Comment #6 from Roman Elshin roman.elshin@gmail.com --- Strange, but mpv --vo=vdpau works.

--- Comment #7 from Roman Elshin roman.elshin@gmail.com --- with 1920x1080 it also hangs (hwdec=vdpau vo=vdpau).

--- Comment #8 from Christian König deathsimple@vodafone.de --- A complete shoot in the dark, but please try to disable semaphores by just returning false from uvd_v2_2_semaphore_emit() in drivers/gpu/drm/radeon/uvd_v2_2.c.
Otherwise I'm running out of ideas what that could be.
The only other explanation I have is that the added load of UVD+displaying at a certain resolution is crashing the GFX block. But I have no idea why that should happen.

--- Comment #9 from Roman Elshin roman.elshin@gmail.com --- bool uvd_v2_2_semaphore_emit(struct radeon_device *rdev, struct radeon_ring *ring, struct radeon_semaphore *semaphore, bool emit_wait) { return false; }
Same things.
