[igt-dev] [PATCH i-g-t 07/31] i915/perf: Enable tests to run on specific engines
Umesh Nerlige Ramappa
umesh.nerlige.ramappa at intel.com
Wed Feb 15 00:46:24 UTC 2023
New perf interface enabled passing engine class instance to the perf
interface. Enable some tests to utlize this interface to run the test on
supported engines.
