[PATCH] drm/915/psr: Set psr.source_ok during atomic_check

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

 



Since commit 4d90f2d507ab ("drm/i915: Start tracking PSR state in crtc
state"), we check whether PSR can be enabled or not in
psr_compute_config(). Given that the psr.source_ok field is supposed to
track this check, set the field in psr_compute_config() as well.

Now tests can distinguish between PSR not enabled due to unmet mode
requirements and something going wrong during commit.
