dmesg
The machine completely freeze using radeonsi driver with FirePro W600, W9000
and W9100.
* Steps to reproduce:
wget
<a href="http://www.phoronix-test-suite.com/benchmark-files/GpuTest_Linux_x64_0.7.0.zip">http://www.phoronix-test-suite.com/benchmark-files/GpuTest_Linux_x64_0.7.0.zip</a>
DISPLAY=:0 ./GpuTest /test=fur /fullscreen
* Acutal result:
System and screen are frozen after a few minutes (sometimes a few seconds,
sometimes 20 min). No mouse/keyboard. Does not respond to ping. No kernel
panic. Requires hard reboot.
After reboot, no error in /var/log/kern.log. Empty dir /var/crash, empty dir
/sys/fs/pstore. Sometimes some nul characters ^@ just before the next "Linux
version".
Using a serial console does not show additional debug messages.
* Expected result:
No system freeze.
* List of things that have been tried but leading to the same result:
- kernel 4.4.X, 4.8.x packaged by ubuntu.
- amd-staging-4.9 from <a href="https://cgit.freedesktop.org/~agd5f/linux">https://cgit.freedesktop.org/~agd5f/linux</a>.
- a few 4.10 kernels from <a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/">http://kernel.ubuntu.com/~kernel-ppa/mainline/</a> .
- radeon.dpm=1 (all values for power_dpm_state /
power_dpm_force_performance_level)
- radeon.dpm=0 (power_mode=profile and all values for power_profile)
- radeon.msi=1 / 0.
- DRI2 / DRI3
- glamor / no accel, TearFree on / off
- single monitor, multi monitor, resolutions 1600x1200, 1920x1080.
- Latest libdrm / mesa. llvm 3.8, 4 and 5.
* List of things that avoids the system freeze:
- radeon.gartsize=512 radeon.vramlimit=1024
* Others:
- apitrace trace then replay does not lead to the freeze.
- No errors with R600_DEBUG=* or MESA_DEBUG.
- strace sometimes shows that the last call is ioctl(RADEON_CS) but not sure
how reliable this is provinding the last print might not be flush.
- Happens with 2 differents brand for the mother board.
- takes a bit longer for the mentioned GpuTest to freeze the machine on W9000
and W9100.
* TODOs:
- Try again kgdb.
- Try amdgpu instead of radeonsi.</pre>
