[PATCH 1/2] drm/i915: Fix modesetting in case of unexpected AUX timeouts

[PATCH 1/2] drm/i915: Fix modesetting in case of unexpected AUX timeouts

[Imre Deak]

In case AUX failures happen unexpectedly during a modeset, the driver
should still complete the modeset. In particular the driver should
perform the link training sequence steps even in case of an AUX failure,
as this sequence also includes port initialization steps. Not doing that
can leave the port/pipe in a broken state and lead for instance to a
flip done timeout.

Fix this by continuing with link training (in a no-LTTPR mode) if the
DPRX DPCD readout failed for some reason at the beginning of link
training. After a successful connector detection we already have the
DPCD read out and cached, so the failed repeated read for it should not
cause a problem. Note that a partial AUX read could in theory partly
overwrite the cached DPCD (and return error) but this overwrite should
not happen if the returned values are corrupted (due to a timeout or
some other IO error).

Kudos to Ville to root cause the problem.

[Intel-gfx] [PATCH 2/2] drm/i915: Drop redundant address-of op before lttpr_common_caps array

[Imre Deak]

The addres-of op in front of an array is just an alias to using the
array on its own, so drop the op.
