[igt-dev] [PATCH i-g-t v5 0/3] Enabling PC8+ residency for all GEN9+ platforms v5

[Anshuman Gupta]

This patch series enable PC8+ residency test, earlier these tests
were only enabled for Haswell and Broadwell.

I have addressed the below review comment provided by Imre
on old series (https://patchwork.freedesktop.org/series/57035/)

1. Made this test future proof to enable for all Gen9+ platform.
2. Added a pc8_needs_screen_off flag to distinguish between HSW/BDW and Gen9+
   Platform.
3. Since Gen9 onwards PC8+ residency doesn't require display to be turned off,
   this patch series tests PC8 residency with all screens on.

Addressed review comment provided by Ram on revision 3
(patch commit log describes the changes).

As earlier this patch series was not lucky to be tested on ICL,
adding the affected test in fast-feedback.testlist.

Planning a separate series for a subtest to validate pc8 with multiple pipes
usages and all planes enabled with max resolution, to create maximum memory
bandwidth scenario.
