During the initial probing of an MST sink, MST core will determine the
sink's link bandwidth based on its own version of the sink link
rate/lane count caps it reads from the DPCD. At a later point (after
probing and 1 or more modesets) i915 may limit the link parameters wrt.
the original source/sink common caps above due to link training failures
during a modeset and the resulting link training fallback logic.
Based on the above a modeset following another modeset with a link
training error will compute the i915 HW specific and DP protocol timing
parameters (data/link M/N and MST TU values) taking into account only
the unlimited source/sink common caps, but not taking into account the
fallback limits. This will also let DRM core oversubscribe the actual
link bandwidth during the MST payload allocation.
Prevent the above problem by disabling the link training fallback on MST
links for now, until the MST probe time initialization and the MST
compute config logic can deal with changing link parameters.
The misconfigured timings lead at least to a
'Timed out waiting for DP idle patterns'
error.
v2: (Ville)
- Print link training error message on the MST path too.
- Clarify the problem in the commit log.

Start using device specific parameters instead of module parameters for
most things. The module parameters become the immutable initial values
for i915 parameters. The device specific parameters in i915->params
start life as a copy of i915_modparams. Any later changes are only
reflected in the debugfs.
The stragglers are:
* i915.force_probe and i915.modeset. Needed before dev_priv is
available. This is fine because the parameters are read-only and never
modified.
* i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
I915_STATE_WARN_ON would result in massive and ugly churn. This is
handled by not exposing the parameter via debugfs, and leaving the
parameter writable in sysfs. This may be fixed up in follow-up work.
* i915.inject_probe_failure. Only makes sense in terms of the module,
not the device. This is handled by not exposing the parameter via
debugfs.

Currently MST on a port can get enabled/disabled from the hotplug work
and get disabled from the short pulse work in a racy way. Fix this by
relying on the MST state checking in the hotplug work and just schedule
a hotplug work from the short pulse handler if some problem happened
during the MST interrupt handling.
This removes the explicit MST disabling in case of an AUX failure, but
if AUX fails, then probably the detection will also fail during the
scheduled hotplug work and it's not guaranteed that we'll see
intermittent errors anyway.
While at it also simplify the error checking of the MST interrupt
handler.
v2:
- Convert intel_dp_check_mst_status() to return bool. (Ville)
- Change the intel_dp->is_mst check to an assert, since after this patch
the condition can't change after we checked it previously.
- Document the return value from intel_dp_check_mst_status().
v3:
- Remove the intel_dp->is_mst check from intel_dp_check_mst_status().
There is no point in checking the same condition twice, even though
there is a chance that the hotplug work running concurrently changes
it.

up doing the right thing (assigning a scaler for pfit).
The code does need to be fixed before any borders are

Also we have redundant calls to skl_update_scaler_crtc() in

called before we had even computed the pfit state so were

TODO: I have a feeling we should just rip this all out and
do a full modeset instead. Stuff like port sync and the tgl+
MST master transcoder stuff maybe doesn't work well if we
try to retrain without following the proper modeset sequence.
So far haven't done any actual tests to confirm that though.

Make intel_dp_check_mst_status() somewhat legible by humans.
Note that the return value of drm_dp_mst_hpd_irq() is always
either 0 or -ENOMEM, and we never did anything with the latter
so we can just ignore the whole thing.
We can also get rid of the direct drm_dp_mst_topology_mgr_set_mst(false)
call since returning -EINVAL causes the caller to do the very same call
for us.

Right now dp.regs.dp_tp_ctl/status are only set during the encoder
pre_enable() hook, what is causing all reads and writes to those
registers to go to offset 0x0 before pre_enable() is executed.
So if i915 takes the BIOS state and don't do a modeset any following
link retraing will fail.
In the case that i915 needs to do a modeset, the DDI disable sequence
will write to a wrong register not disabling DP 'Transport Enable' in
DP_TP_CTL, making a HDMI modeset in the same port/transcoder to
not light up the monitor.
So here for GENs older than 12, that have those registers fixed at
port offset range it is loading at encoder/port init while for GEN12
it will keep setting it at encoder pre_enable() and during HW state
readout.

We're going to want access to the atomic state for iterating
the slave crtcs when enabling the port sync master crtc. Pass
the atomic state all the way down.
The alternative would be yet another encoder hook which we'll
have to call after all the normal modeset stuff is done. Not
really a fan of yet another hook just for this.
Note that during readout state sanitation we are now going
to pass NULL as the atomic state since we don't have one.
We need to change that and then we can also s/crtc_state/crtc/
and s/conn_state/conn/ for the encoder hooks as well.

Transcoder port sync was introduced to the hardware in BDW. We
can trivially enable it for SKL+ since the same codepaths are
already used for ICL+ port sync. The only difference is the actual
location of the bits we need to poke.
We leave BDW out (at least for now) since it uses different modeset
paths that haven't been adapted for port sync, and IIRC using the
feature would involve some extra workarounds we've not implemented.
Pre-BDW hardware does not support port sync so we'd have to tweak
the modeset sequence to start the pipes as close together as possible
and hope for the best. So far no one has seriously tried to implement
that.

Few edp panels like Sharp is triggering short and long
hpd pulse after panel is getting powered off.
Currently driver is already ignoring long pulse for eDP
panel but in order to process the short pulse, it turns on
the VDD which requires panel power_cycle_delay + panel_power_on_delay
these delay on Sharp panel introduced the responsiveness overhead
of 800ms in the modeset sequence and as well is in suspend
sequence.
Ignoring any short pulse if panel is powered off.
FIXME: It requires to wait for panel_power_off delay in order
to check the panel power status due to pps_lock because panel triggers
short pulse immediately after writing PP_OFF to PP_CTRL register and
wait_panel_off waits for panel_power_off delay with pps_lock held.
This still creates responsiveness overhead of panel_power_off delay.
v2:
- checking vdd along with panel power to ignore the hpd. [Jani,Ville]
v3:
- safer side check to ignore the long hpd when eDP have power,
adding type of hpd to debug log. [Jani]
