* [Intel-gfx] [PATCH i-g-t v3] i915/gem_exec_balancer: Randomise bonded submission
@ 2020-05-29 13:58 ` Chris Wilson

From: Chris Wilson @ 2020-05-29 13:58 UTC (permalink / raw)
  To: intel-gfx; +Cc: igt-dev, Chris Wilson

Randomly submit a paired spinner and its cancellation as a bonded
(submit fence) pair. Apply congestion to the engine with more bonded
pairs to see if the execution order fails. If we prevent a cancellation
from running, then the spinner will remain spinning forever.

v2: Test both immediate submission and fenced submission
v3: Copy-n-paste a single context variant

* [igt-dev] [PATCH i-g-t v3] i915/gem_exec_balancer: Randomise bonded submission
@ 2020-05-29 13:58 ` Chris Wilson
  0 siblings, 0 replies; 8+ messages in thread
From: Chris Wilson @ 2020-05-29 13:58 UTC (permalink / raw)
  To: intel-gfx; +Cc: igt-dev, Tvrtko Ursulin, Chris Wilson

Randomly submit a paired spinner and its cancellation as a bonded
(submit fence) pair. Apply congestion to the engine with more bonded
pairs to see if the execution order fails. If we prevent a cancellation
from running, then the spinner will remain spinning forever.

v2: Test both immediate submission and fenced submission
v3: Copy-n-paste a single context variant
