[igt-dev] [PATCH i-g-t v7 0/4] Enabling PC8+ residency for all GEN9+ platforms v7

[Anshuman Gupta]

This is resubmission after removing debug subtest pc8-residency-all-pipes-planes.
https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_3107/? results are proving that
platforms which are passing pc8 residency subtest, are able to enter pc8 even
with all planes are enabled on all pipes. This states that gen9 onward platform.
can enter pc8 with all connected display being on, which was not clear from specs.

As we do not want to file bug for pc8-residency-all-pipes-planes
debug test, resubmitting the series after removing it.

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

This revision has addressed minor review comment provided by Ram on revision 6.

Earlier pc8-residency sub-test were failing on most of Gen 9
platforms, so trying pc8-residency sub test after setting up powertop
and dumping the pmc sysfs attributes.
