To: intel-gfx; +Cc: David Airlie, linux-kernel, dri-devel
Something that I completely missed when implementing the new MST VCPI
atomic helpers is that with those helpers, there's technically a chance
of us having to grab additional modeset locks in ->compute_config() and
furthermore, that means we have the potential to hit a normal modeset
deadlock. However, because ->compute_config() only returns a bool this
means we can't return -EDEADLK when we need to drop locks and try again
which means we end up just failing the atomic check permanently. Whoops.
So, fix this by modifying ->compute_config() to pass down an actual
error code instead of a bool so that the atomic check can be restarted
on modeset deadlocks.
Thanks to Ville Syrjälä for pointing this out!

Hmm. At first glance I was rather confused that you didn't change
anything here, but indeed this guy already does what we want.

Here we can propagate the return value from

You changed intel_dp_dsc_compute_config() but didn't update the caller?
Probably best to change all the intel_dp_compute_link_config*() functions
to return an int as well for consistency.

Oh wow. I just noticed that a1b2278e4dfc ("drm/i915: skylake panel fitting
using shared scalers") already assumed that .compute_config() returns
an int. That might even explain some oddball scaler fails people have
seen.
