[PATCH] drm/i915/display/psr: Add sink not reliable check to intel_psr_work()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If the sink state is not reliable, it does not need to wait for
PSR "IDLE state" for re-enabling PSR. And it should not try to re-enable
PSR.
