[Intel-gfx] [PATCH IGT 00/11] IGT PSR Fix-ups

[Jim Bride]

These patches, along with the kernel series at
https://patchwork.freedesktop.org/series/27137/ allow our PSR
IGT tests to run more predictably on HSW, BDW, and SKL.  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 still see some very sporadic (every few hundred tests executions or so)
failures to read the sink CRC.

HSW:
	* kms_psr_sink_crc (all)
	* kms_frontbuffer_tracking (subtests psr-1p*, my system doesn't
	  support FBC)
	* kms_fbcon_fbt (subtests psr*)

BDW and SKL:
        * kms_psr_sink_crc (all)
    	* kms_frontbuffer_tracking (subtests psr-1p* and fbcpsr-1p*)
	* kms_fbcon_fbt (subtests psr*)

Note: Based on review feedback the changes in this series were
      substantially restructured vs. previous versions.

Jim Bride (11):
  tests/kms_psr_sink_crc: Change assert_or_manual() to a macro
  tests/kms_frontbuffer_tracking: Fix multidraw subtest
  tests/kms_frontbuffer_tracking: Remove unneeded HSW work-around.
