[Intel-gfx] [PATCH v2 00/11] drm/i915: Plumb crtc state to link training code

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Another attempt at plumbing the crtc state to the depths of
the link training code. This time I tried to preserve the
PHY test stuff in a somewhat working condition.

The DDI buf trans stuff also started to bug me again so had 
to toss in a few cleanups in that area. Still pretty messy,
but with a bit more regular structure we could perhaps toss
in a few vfuncs to get rid of some if ladders at least.
Not entirely sure yet...

[Intel-gfx] [PATCH v2 02/11] drm/i915: s/old_crtc_state/crtc_state/

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

intel_dp_enable_port() is called during the enable sequence,
so there is nothing old about the passed in crtc state.
Rename it.

[Intel-gfx] [PATCH v2 04/11] drm/i915: Shove the PHY test into the hotplug work

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Doing nay kind modeset stuff from the short hpd handler is
verboten. The ad-hoc PHY test modeset code violates this. And
by calling various link training related functions it's now
blocking further work to plumb the crtc state down into the
link training code.

Let's hack around that by pushing the PHY test stuff into the
hotplug work where it's less of a problem. Still not great but
at least acceptable. We take a few pages from the link retraining
handbook to handle the locking and whatnot.

[Intel-gfx] [PATCH v3 04/11] drm/i915: Shove the PHY test into the hotplug work

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Doing nay kind modeset stuff from the short hpd handler is
verboten. The ad-hoc PHY test modeset code violates this. And
by calling various link training related functions it's now
blocking further work to plumb the crtc state down into the
link training code.

Let's hack around that by pushing the PHY test stuff into the
hotplug work where it's less of a problem. Still not great but
at least acceptable. We take a few pages from the link retraining
handbook to handle the locking and whatnot.

v2: Fix the intel_dp_hotplug() return value

[Intel-gfx] [PATCH v2 10/11] drm/i915: Plumb crtc_state to link training

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Get rid of mode crtc->config usage, and some ad-hoc intel_dp state
usage by plumbing the crtc state all the way down to the link training
code.

Unfortunately we do have to keep some cached state in intel_dp so
that we can do the "does the link need retraining?" checks from
the short hpd handler.

v2: Add intel_crtc_state forward declaration
v3: Don't kill the PHY test code totally since it's
    now in the hotplug work where we can get at the states

Looks like a bugfix and then would make sense to fix it in a separate
patch.

Disable scrambling looks like some HW debugging feature, the HW toggles it
automatically based on the spec. There was a recent related change
removing setting it in intel_ddi_set_link_train().

If needed, it should be a separate change imo.

Didn't even notie this one. I need to check whether it's a current bug
or if I just fumbled the earlier patches somehow.

This is just a rebase fail on my part I think.
Thanks for catching it.

Ack. Didn't remember we had such a thing.

[Intel-gfx] [PATCH v4 10/11] drm/i915: Plumb crtc_state to link training

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Get rid of mode crtc->config usage, and some ad-hoc intel_dp state
usage by plumbing the crtc state all the way down to the link training
code.

Unfortunately we do have to keep some cached state in intel_dp so
that we can do the "does the link need retraining?" checks from
the short hpd handler.

v2: Add intel_crtc_state forward declaration
v3: Don't kill the PHY test code totally since it's
    now in the hotplug work where we can get at the states
v4: Don't resurrect the debug scrambling disable bit (Imre)
    Use intel_dp_mst_is_master_trans() (Imre)

[Intel-gfx] [PATCH v2 11/11] drm/i915: Eliminate intel_dp.regs.dp_tp_{ctl, status}

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Now that we've plumbed the crtc state all the way down we can
eliminate the DP_TP_{CTL,STATUS} register offsets from intel_dp,
and instead we derive them directly from the crtc state.

And thus we can get rid of the nasty hack in intel_ddi_get_config()
which mutates intel_dp during the readout.
