Very light stress test to bombard the submission backends with a large stream with requests of randomly assigned priorities. Preemption will be occasionally requested, but unlikely to ever succeed! (Although we may build a long queue of requests and so may trigger an attempt to inject a preempt context, as we emit no batch, the arbitration window is limited to between requests inside the ringbuffer. The likelihood of actually causing a preemption event is therefore very small. A later variant should try to improve the likelihood of preemption events!) v2: Include a second pattern with more frequent preemption Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michał Winiarski <michal.winiarski@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180925083205.2229-1-chris@chris-wilson.co.uk |
