[igt-dev] [PATCH i-g-t 1/2] tests/intel/kms_psr: Add FBC support to PSR/PSR2 tests

[Jeevan B]

For intel_display_ver 20, FBC can be enabled along with PSR/PSR2,
thereby adding FBC checks to validate this scenario.

Could you write here (maybe in braces) platfrom name?
Or maybe other way around, something like:

For LunarLake (intel_display_ver 20) FBC can be enabled ... rest of description

----------- ^

Looks like this is breaking convetion for (sub)tests name:
very-long-subtest-name, now it is very_long_subtest_name.

Was it intended? +cc Swati, Bhanu and Juha-Pekka.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For intel_display_ver 20, FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For LunarLake (intel_display_ver 20), FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For intel_display_ver 20, FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.

[igt-dev] [PATCH i-g-t 2/2] tests/intel/kms_psr2_sf: Add FBC support to PSR2 tests

[Jeevan B]

For intel_display_ver 20, FBC can be enabled along with PSR2,
thereby adding FBC checks to validate this scenario.
