[igt-dev] [i-g-t] tests/kms_atomic_transition: Convert tests to dynamic

Bhanuprakash Modem bhanuprakash.modem at intel.com
Wed Aug 10 10:52:12 UTC 2022


Convert the existing subtests to dynamic subtests at pipe/output
level. And create an array of structures to populate subtests to
avoid code duplication.

This patch will also sanitize the system state before starting the
subtest with igt_display_reset().
