[PATCH v5 1/2] drm/i915: Disable fast link training if DP config changes

[Mika Kahola]

Disable DP link training optimization if DP link configuration
changes. If one of the DP link parameters i.e. link rate or
lane count changes the link training does no longer apply the
previously computed drive current and pre-emphasis level.
Instead, the link training is started with zero values.

v5: Commit message update. Split the original patch in two.
    This part considers only changes on link configuration.
    Removed unnecessary debug messages. (Ville)

v4: Parameter and debug message naming improvements.
    Fix for link parameter check (Ville)

v3: Remove cached old link parameters. Instead, disable
    fast link training feature when link parameters are
    set (Ville)

v2: Readout DPCD register to check if no aux handshaking is
    required in link training (Ander)

[PATCH v5 2/2] drm/i915: Check DP no aux transaction bit on link training

[Mika Kahola]

Check if no AUX transactions are required on DP link training.
If this bit is set, we can reuse the known good drive current
and pre-emphasis level from the last "full" link training.

If Thierry Reding's patches get merged (posted to dri-devel@ on Dec 14
with <1450097764-30063-1-git-send-email-thierry.reding@gmail.com>),
you could just use

	if (has_dpcd && drm_dp_fast_training_cap(intel_dp->dpcd))
		intel_dp->train_set_valid &= true;

Also, if the patches get merged, the no_aux_handshake attribute in dev_priv
can be dropped (set in intel_edp_init_connector() but never read).

Best regards,

Lukas

Good points, but we don't generally write code, let alone bugfixes, on
top of code that hasn't been merged.

The commit message here isn't entirely accurate. You still need AUX
transactions to configure the link according to the values obtained
from the last full training sequence.
