Bug ID: 107204 Summary: GPU hang (ring gfx timeout) in OpenGL game Product: Mesa Version: git Hardware: All OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: fbz-me@milek7.pl QA Contact: dri-devel@lists.freedesktop.org
Created attachment 140587 --> https://bugs.freedesktop.org/attachment.cgi?id=140587&action=edit Dumps from GALLIUM_DDEBUG
It hangs in OpenGL game immediately after startup almost always (but sometimes it goes through and works) with dmesg message:
[drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, last signaled seq=3324, last emitted seq=3327
I tested it on Radeon RX580, mainline kernel 4.18, Mesa 18.1.3 and Mesa git c0874947f1.
I could provide game code for testing but I would have to package minimal assets as full game weights pretty much.

--- Comment #1 from Miłosz Rachwał fbz-me@milek7.pl --- It turned out that the cause was uninitialized UBO, which depending on memory contents leaded to out of bounds UBO array read in fragment shader. It probably shouldn't bring down whole GPU, though.
