[igt-dev] [PATCH i-g-t v2] tests/kms_content_protection: Convert tests to Dynamic
Karthik B S
karthik.b.s at intel.com
Fri Sep 9 05:17:24 UTC 2022
Covert the existing subtests to dynamic subtests at pipe/output level.
Also move the cleanup part outside the subtest so that it is run even if
a failure is seen in the subtest.
v2: -Try other pipe/output combo for MST if failure is seen on one
-Remove redundant mode_override
-Misc cleanup
