[igt-dev] [PATCH i-g-t v6 0/4] Enabling PC8+ residency for all GEN9+ platforms v6

[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).

Earlier pc8-residency sub-test were failing on most of Gen 9
platforms, so trying pc8-residency sub test after setting up powertop
and pmc lte_ignore one by one (This is additional debug patch).

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