[Intel-gfx] [PATCH v2 00/16] arb robustness enablers v2

[Mika Kuoppala]

Hi,

Reworked patchset for guilty context detection.
Main changes since the last posting:
- i915_add_request cleanup
- i915_switch_context returns ERR_PTR
- 3 seconds to declare hang regardless if guilty was found
- semaphore kicking for hung rings (from Chris)
- test case for the new interface
- interface is now included to have common base for discussions.

Thank you all who provided feedback.

And testcase for i-g-t here:
