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.
