i915 error state for GPU hang
Setup:
- SKL i5 6600K
- Ubuntu 16.04
- drm-tip git kernel (0330b51e91)
- Mesa git (5ed4e31c08d)
- Unity desktop
Test-case:
- 3x fullscreen FullHD HDRBloom multi-context SynMark test-case:
synmark2 OglHdrBloom
Actual outcome:
- Recoverable GPU hang, but all successive GL tests fail after that:
i915 0000:00:02.0: GPU HANG: ecode 9:1:0x00000000, hang on rcs0
Main difference from this test to most other tests is only few tests use
multiple contexts.
I haven't seen such hangs with the i965 driver.
I wasn't able to reproduce the hang after reboot when re-running HDRBloom 10
times, so it may depend on previous tests, or is just very hard to reproduce.
I didn't see such hang when running similar test-sets month ago, so it can be a
regression.
On BXT there was a hang in a different test-case.</pre>
