[igt-dev] [PATCH i-g-t v4 0/2] Enabling PC8+ residency for all GEN9+ platforms v4

[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).

Tested on Gen9 KBL Platform, unable to test on ICL, because ICL systems at local
BA setup are not entering to PC2 itself.

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.
