--- Comment #7 from Matt Roper <matthew.d.roper at intel.com> ---
All failures attached to this bug are on the fi-whl-u machine and from the logs
it appears the panel on this machine is considered unreliable:

  <7> [264.149232] [drm:intel_dp_compute_config [i915]] PSR sink implementation
is not reliable

which causes the driver to force PSR support off.  IGT is just looking for the
string "Sink support: yes [0x03]" in debugfs to know whether a panel support
PSR2 or not, but maybe we should also expose the unreliable panel flag through
debugfs too and have IGT also confirm that that flag is not set before
attempting the test?
