[PATCH 00/22] drm/i915: Bigjoiner modeset sequence redesign and MST support

[Ville Syrjala]

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

I started to look at the MST+bignoier stuff floating around
and then decided that there's just too much noise in the way,
and so did a quick pass over the whole thing to clean and
fix things up ahead of time.

I then applied the stuff from Stan and Vidya on top of what
I had and fixed it up enough to do a quick smoke test on my
ADL. It survived a 2x2 MST configuration with uncompressed
joiner enabled on both outputs. I don't have any DSC capable
hardware around so couldn't test bigjoiner.

Anyways, here's the whole pile for people to ruminate
over during Easter.

Also pushed it here:

[PATCH 01/22] drm/i915: Disable port sync when bigjoiner is used

[Ville Syrjala]

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

The current modeset sequence can't handle port sync and bigjoiner
at the same time. Refuse port sync when bigjoiner is needed,
at least until we fix the modeset sequence.

[PATCH 02/22] drm/i915: Fix intel_modeset_pipe_config_late() for bigjoiner

[Ville Syrjala]

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

Currently intel_modeset_pipe_config_late() is called after the
bigjoiner state copy, and it will actually not do anything for
bigjoiner slaves. This can lead to a mismatched state between
the master and slave.

The two things that we do in the encoder .compute_config_late()
hook are mst master transcoder and port sync master transcoder
elections. So if either of either MST or port sync is combined
with bigjoiner then we can see the mismatch.

Currently this problem is more or less theoretical; MST+bigjoiner
has not been implemented yet, and port sync+bigjoiner would
require a tiled display with >5k tiles (or a very high
dotclock per tile). Although we do have kms_tiled_display in
igt which can fake a tiled display, and we can now force bigjoiner
via debugfs, so it is possible to trigger this if you try hard
enough.

Reorder the code such that intel_modeset_pipe_config_late()
will be called before the bigjoiner state copy happens so
that both pipes will end up with the same state.

[PATCH 03/22] drm/i915: Disable live M/N updates when using bigjoiner

[Ville Syrjala]

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

All joined pipes share the same transcoder/timing generator.
Currently we just do the commits per-pipe, which doesn't really
work if we need to change the timings at the same time. For
now just disable live M/N updates when bigjoiner is needed.

[PATCH 04/22] drm/i915/vrr: Disable VRR when using bigjoiner

[Ville Syrjala]

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

All joined pipes share the same transcoder/timing generator.
Currently we just do the commits per-pipe, which doesn't really
work if we need to change switch between non-VRR and VRR timings
generators on the fly, or even when sending the push to the
transcoder. For now just disable VRR when bigjoiner is needed.

[PATCH 05/22] drm/i915: Remove DRM_MODE_FLAG_DBLSCAN checks from .mode_valid() hooks

[Ville Syrjala]

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

We never set connector->doublescan_allowed, so the probe helper
already filters out all doublescan modes for us.

Sadly we still need to keep the explicit doublescan checks
in .compute_config as outlined in commit e4dd27aadd20
("drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSI")

[PATCH 11/22] drm/i915/mst: Check intel_dp_joiner_needs_dsc()

[Ville Syrjala]

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

intel_dp_mst_compute_config() is missing the "does the
joiner need DSC?" check despite claiming to have a lot
of other joiner/dsc stuff in there (albeit disabled).
Replicate the logic from the SST side.

TODO: refactor all this duplicated code!

[PATCH 13/22] drm/i915/mst: Limit MST+DSC to TGL+

[Ville Syrjala]

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

The MST code currently assumes that glk+ alerady supports MST+DSC,
which is incorrect. We need to check for TGL+ actually. ICL does
support SST+DSC, but supposedly it can't do MST+FEC which will
also rule MST+DSC.

Note that a straight TGL+ check doesn't work here because DSC
support can get fused out, so we do need to also check 'has_dsc'.

[PATCH 15/22] drm/i915: Introduce intel_crtc_joined_pipe_mask()

[Ville Syrjala]

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

Add a small helper to compute the set of pipes that the current
crtc is using.

And we have at least one trivial place in
intel_ddi_update_active_dpll() where we can use it
immediately, so let's do that.

v2: Use the name 'pipe_crtc' for the per-pipe crtc pointer

[PATCH 16/22] drm/i915: Extract intel_ddi_post_disable_hdmi_or_sst()

[Ville Syrjala]

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

Extract the "not-MST" stuff from intel_ddi_post_disable() so that
the whole thing isn't so cluttered.

The bigjoiner slave handling was outside of the !MST check,
but it really should have been inside it as its the counterpart
to the master handling inside the check. So we pull that
in as well. There is no functional change here as we don't
currently support bigjoiner+MST anyway.

v2: Rebase

[PATCH 17/22] drm/i915: Utilize intel_crtc_joined_pipe_mask() more

[Ville Syrjala]

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

Unify the master vs. slave handling in
intel_ddi_post_disable_hdmi_or_sst() by looping over all the
pipes in one go.

This also lets us move the intel_crtc_vblank_off() calls to
happen in a consistent place vs. the transcoder disable.
Previously we did the master vs. slaves on different sides
of that.

[PATCH 18/22] drm/i915: Handle joined pipes inside hsw_crtc_disable()

[Ville Syrjala]

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

Reorganize the crtc disable path to only deal with the
master pipes/transcoders in intel_old_crtc_state_disables()
and offload the handling of joined pipes to hsw_crtc_disable().
This makes the whole thing much more sensible since we can
actually control the order in which we do the per-pipe vs.
per-transcoder modeset steps.

[PATCH 19/22] drm/i915: Handle joined pipes inside hsw_crtc_enable()

[Ville Syrjala]

From: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com>

Handle only bigjoiner masters in skl_commit_modeset_enables/disables,
slave crtcs should be handled by master hooks. Same for encoders.
That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave.

v2: - Moved skl_pfit_enable, intel_dsc_enable, intel_crtc_vblank_on to intel_enable_ddi,
      so that it is now finally symmetrical with the disable case, because currently
      for some weird reason we are calling those from skl_commit_modeset_enables, while
      for the disable case those are called from the ddi disable hooks.
v3: - Create intel_ddi_enable_hdmi_or_sst symmetrical to
      intel_ddi_post_disable_hdmi_or_sst and move it also under non-mst check.
v4: - Fix intel_enable_ddi sequence
    - Call intel_crtc_update_active_timings for slave pipes as well
[v5: vsyrjala: Use the name 'pipe_crtc' for the per-pipe crtc pointer
               Use consistent style and naming
	       Protect macro arguments properly
               Drop superfluous changes to the modeset sequence,
	       this now follows the old non-joiner sequence 100%
	       apart from just looping in places]

[PATCH 20/22] drm/i915/mst: Add bigjoiner handling to MST modeset sequence

[Ville Syrjala]

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

Loop over all joined pipes at relevant points in the MST
modeset sequence.

Carved out from Vidya's earlier big patch, with naming/etc.
changed to match the earlier hsw_crtc_enable() stuff.

[PATCH 21/22] drm/i915: Allow bigjoiner for MST

[Ville Syrjala]

From: Vidya Srinivas <vidya.srinivas@intel.com>

We need bigjoiner support with MST functionality
for MST monitor resolutions > 5K to work.
Adding support for the same.

v2: Addressed review comments from Jani.
Revert rejection of MST bigjoiner modes and add
functionality

v3: Fixed pipe_mismatch WARN for mst_master_transcoder
Credits-to: Manasi Navare <navaremanasi@chromium.org>

v4: Utilize intel_crtc_joined_pipe_mask() also for handling
    bigjoiner slave pipes for MST case(Stan)
[v5: vsyrjala: chunked the modeset squence stuff out,
               removed bogus mst master transcoder hack,
	       keep mgr_lock near the full_pbn check]

There is no reason to make this debugfs file for a simple

Like you have said in the second patch in the series " port sync+bigjoiner would require a tiled display with >5k tiles (or a very high dotclock per tile)." this would be a rare case, since it needs to be fixed later, a todo comment would be helpful, to take care of it for later.
With that

The correct disable order is:
1. encoder disable()
2. disable transcoder/etc. (nop for hsw+ as that stuff
   has been sucked into the encoder hooks)
3. encoder post_disable()
4. pll disable
5. encoder post_pll_disable()

which we should be following here, thouh the diff is
rather hard to read due to the indentation changes.
