[Intel-gfx] [PATCH IGT 0/5] PSR IGT Test Fix-ups

[Jim Bride]

These patches, along with the kernel series at
https://patchwork.freedesktop.org/series/24049/ allow our PSR
IGT tests to run more predictably on HSW, SKL, and KBL.  These
patches depend on the kernel series in order to run properly.  On
the systems I have available the following sets of tests run and pass.
I expect that tests would also pass on BDW, but I don't have access to
a BDW system with a PSR panel.  I still see some very sporadic (every
few hundred tests executions or so) failures to read the sink CRC on
KBL, but it is much less common than what we were seeing in the past.

HSW:
	* kms_psr_sink_crc (all)
	* kms_frontbuffer_tracking (subtests psr-1p*, my system doesn't
	  			    have a FBC panel or a DP port)
	* kms_fbcon_fbt (subtests psr*)

SKL and KBL:
	* kms_psr_sink_crc (all)
	* kms_frontbuffer_tracking (subtests psr* and fbcpsr*)
	* kms_fbcon_fbt (all)
