[PATCH 0/6] Bigjoiner refactoring

[PATCH 0/6] Bigjoiner refactoring

[Stanislav Lisovskiy]

There are few things we need to do for bigjoiner, in order
to improve code maintenance and also make testing for Bigjoiner
easier.
Those series contain addition of bigjoiner force debugfs option,
in order to be able to force bigjoiner even if there is no display
support, also we refactor pipe vs transcoder logic, as currently
it is a bit scattered between *_commit_modeset_enables/disables
and *_crtc_enable/disable functions. Same applies to encoders.
We made a decision to handle all the slaves in correspondent master
hook, so slaves and slave checks no longer would be in modesetting
level logic.

Stanislav Lisovskiy (5):
  Add a small helper to compute the set of pipes that the current crtc
    is using.
  drm/i915: Extract intel_ddi_post_disable_hdmi_or_sst()
  drm/i915: Utilize intel_crtc_joined_pipe_mask() more
  drm/i915: Handle joined pipes inside hsw_crtc_disable()
  drm/i915: Handle joined pipes inside hsw_crtc_enable()

[PATCH 1/6] Add a small helper to compute the set of pipes that the current crtc is using.

[Stanislav Lisovskiy]

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: - Fixed conflicts, part of patch didn't apply, because of master_crtc
      rename(Stan)

[PATCH 2/6] drm/i915: Extract intel_ddi_post_disable_hdmi_or_sst()

[Stanislav Lisovskiy]

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.

This bigjoiner slave handling for MST path will be added later to the
intel_ddi_post_post_disable()
when we enable bigjoiner for MST?

Hi Manasi, yes, currently I'm evaluating what would be the best way
to do that.

[PATCH 3/6] drm/i915: Utilize intel_crtc_joined_pipe_mask() more

[Stanislav Lisovskiy]

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.

How will we handle looping through all joined pipes for MST case,
does this need to be accounted for in the last patch that enables bigjoiner
for MST now that we have separated out ddi_post_disable for hdmi/sst?

[PATCH 4/6] drm/i915: Handle joined pipes inside hsw_crtc_disable()

[Stanislav Lisovskiy]

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.

v2: Fixed rebase conflict(intel_crtc_state_disables signature had changed)

[PATCH 5/6] drm/i915: Handle joined pipes inside hsw_crtc_enable()

[Stanislav Lisovskiy]

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.

[PATCH 6/6] drm/i915: Allow bigjoiner for MST

[Stanislav Lisovskiy]

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

Re: [PATCH 6/6] drm/i915: Allow bigjoiner for MST

[Manasi Navare]

Now when we enable bigjoiner for MST, in MST case
intel_ddi_post_disable_hdmi_or_sst() function wont get called,
Do we need similar changes for MST case to loop over the joined pipes
in MST bigjoiner case?

[PATCH 0/6] Bigjoiner refactoring

[Stanislav Lisovskiy]

There are few things we need to do for bigjoiner, in order
to improve code maintenance and also make testing for Bigjoiner
easier.
Those series contain addition of bigjoiner force debugfs option,
in order to be able to force bigjoiner even if there is no display
support, also we refactor pipe vs transcoder logic, as currently
it is a bit scattered between *_commit_modeset_enables/disables
and *_crtc_enable/disable functions. Same applies to encoders.
We made a decision to handle all the slaves in correspondent master
hook, so slaves and slave checks no longer would be in modesetting
level logic.

[PATCH 6/6] drm/i915: Allow bigjoiner for MST

[Stanislav Lisovskiy]

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)
