Priority: medium Bug ID: 77907 Assignee: dri-devel@lists.freedesktop.org Summary: OpenCL test 'Arithm/Absdiff.Mat/20' from OpenCV hangs HD5470M Severity: normal Classification: Unclassified OS: Linux (All) Reporter: brunojimen@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
The effects are that when running that test, the screen freezes for a while, then goes to black, then shows back my desktop, happening this some times.
After some debugging, the hang seems to occur with the compute shader sent to the GPU, as the system freezes when it waits for the GPU to finish.
My system is Arch Linux with: - AMD CEDAR 5470M - kernel 3.14.1-1 - llvm at revision 207118 - mesa at commit 352e06d - opencv at commit bb4199b

--- Comment #3 from Bruno Jiménez brunojimen@gmail.com --- Created attachment 97924 --> https://bugs.freedesktop.org/attachment.cgi?id=97924&action=edit Here's the lockup code I obtained using R600_DEBUG=trace_cs
This code does indeed hang my GPU in the same way (as far as I can see) that the test does.
