[Intel-gfx] [PATCH v15 01/14] drm/i915/dp: Some reshuffling in mode_valid as prep for bigjoiner modes

[Manasi Navare]

No functional changes. This patch just moves some mode checks
around to prepare for adding bigjoiner related mode validation

[Intel-gfx] [PATCH v15 02/14] drm/i915: Move encoder->get_config to a new function

[Manasi Navare]

No functional changes, create a separate intel_encoder_get_config()
function that calls encoder->get_config hook.
This is needed so that later we can add beigjoienr related
readout here.

[Intel-gfx] [PATCH v15 04/14] drm/i915: Add hw.pipe_mode to allow bigjoiner pipe/transcoder split

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

With bigjoiner, there will be 2 pipes driving 2 halves of 1 transcoder,
because of this, we need a pipe_mode for various calculations, including
for example watermarks, plane clipping, etc.

v10:
* remove redundant pipe_mode assignment (Ville)
v9:
* pipe_mode in state dump nd state check (Ville)
v8:
* Add pipe_mode in readout in verify_crtc_state (Ville)
v7:
* Remove redundant comment (Ville)
* Just keep mode instead of pipe_mode (Ville)
v6:
* renaming in separate function, only pipe_mode here (Ville)
* Add description (Maarten)
v5:
* Rebase (Manasi)
v4:
* Manual rebase (Manasi)
v3:
* Change state to crtc_state, fix rebase err  (Manasi)
v2:
* Manual Rebase (Manasi)

[Intel-gfx] [PATCH v15 05/14] drm/i915: Pass intel_atomic_state instead of drm_atomic_state

[Manasi Navare]

No functional changes, to align with previous cleanups pass
intel_atomic_state instead of drm_atomic_state.
Also pass this intel_atomic_state with crtc_state to
some of the atomic_check functions.

v2:
* Squash some changes from next patch (Ville)

[Intel-gfx] [PATCH v15 07/14] drm/i915/dp: Allow big joiner modes in intel_dp_mode_valid(), v3.

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Small changes to intel_dp_mode_valid(), allow listing modes that
can only be supported in the bigjoiner configuration, which is
not supported yet.

v13:
* Allow bigjoiner if hdisplay >5120
v12:
* slice_count logic simplify (Ville)
* Fix unnecessary changes in downstream_mode_valid (Ville)
v11:
* Make intel_dp_can_bigjoiner non static
so it can be used in intel_display (Manasi)
v10:
* Simplify logic (Ville)
* Allow bigjoiner on edp (Ville)
v9:
* Restric Bigjoiner on PORT A (Ville)
v8:
* use source dotclock for max dotclock (Manasi)
v7:
* Add can_bigjoiner() helper (Ville)
* Pass bigjoiner to plane_size validation (Ville)
v6:
* Rebase after dp_downstream mode valid changes (Manasi)
v5:
* Increase max plane width to support 8K with bigjoiner (Maarten)
v4:
* Rebase (Manasi)

Changes since v1:
- Disallow bigjoiner on eDP.
Changes since v2:
- Rename intel_dp_downstream_max_dotclock to intel_dp_max_dotclock,
  and split off the downstream and source checking to its own function.
  (Ville)
v3:
* Rebase (Manasi)

[Intel-gfx] [PATCH v15 08/14] drm/i915: Try to make bigjoiner work in atomic check

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

 When the clock is higher than the dotclock, try with 2 pipes enabled.
 If we can enable 2, then we will go into big joiner mode, and steal
 the adjacent crtc.

 This only links the crtc's in software, no hardware or plane
 programming is done yet. Blobs are also copied from the master's
 crtc_state, so it doesn't depend at commit time on the other
 crtc_state.

v6:
* Enable dSC for any mode->hdisplay > 5120
v5:
* Remove intel_dp_max_dotclock (Manasi)
v4:
* Fixes in intel_crtc_compute_config (Ville)
v3:
* Manual Rebase (Manasi)
 Changes since v1:
 - Rename pipe timings to transcoder timings, as they are now different.
  Changes since v2:
 - Rework bigjoiner checks; always disable slave when recalculating
   master. No need to have a separate bigjoiner pass any more.
 - Use pipe_mode instead of transcoder_mode, to clean up the code.

[Intel-gfx] [PATCH v15 09/14] drm/i915/dp: Modify VDSC helpers to configure DSC for Bigjoiner slave

[Manasi Navare]

Make vdsc work when no output is enabled. The big joiner needs VDSC
on the slave, so enable it and set the appropriate bits.
So remove encoder usage from dsc functions.

[Intel-gfx] [PATCH v15 10/14] drm/i915/dp: Master/Slave enable/disable sequence for bigjoiner

[Manasi Navare]

Enabling is done in a special sequence and so should plane updates
be. Ideally the end user never notices the second pipe is used.

This way ideally everything will be tear free, and updates are
really atomic as userspace expects it.

This uses generic modeset_enables() calls like trans port sync
but still has special handling for disable since for slave we
should not disable things like encoder, plls that are not enabled
for  slave.

[Intel-gfx] [PATCH v15 11/14] drm/i915: HW state readout for Bigjoiner case

[Manasi Navare]

Skip iterating over bigjoiner slaves, only the master has the state we
care about.

Add the width of the bigjoiner slave to the reconstructed fb.

Hide the bigjoiner slave to userspace, and double the mode on bigjoiner
master.

And last, disable bigjoiner slave from primary if reconstruction fails.

Signed-off-by: Manasi Navare <manasi.d.navare@intel.com>

v3:
* Fix the ddi_get_config slave error (Ankit Nautiyal)
v2:
* Unsupported bigjoiner config for initial fb (Ville)

[Intel-gfx] [PATCH v15 12/14] drm/i915: Link planes in a bigjoiner configuration, v3.

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

 Make sure that when a plane is set in a bigjoiner mode, we will add
 their counterpart to the atomic state as well. This will allow us to
 make sure all state is available when planes are checked.

Because of the funny interactions with bigjoiner and planar YUV
formats, we may end up adding a lot of planes, so we have to keep
iterating until we no longer add any planes.

Also fix the atomic intel plane iterator, so things watermarks start
working automagically.

v6:
* Fix from_plane_state assignments (Manasi)
v5:
* Rebase after adding sagv support (Manasi)
v4:
* Manual rebase (Manasi)
Changes since v1:
- Rebase on top of plane_state split, cleaning up the code a lot.
- Make intel_atomic_crtc_state_for_each_plane_state() bigjoiner capable.
- Add iter macro to intel_atomic_crtc_state_for_each_plane_state() to
  keep iteration working.
Changes since v2:
- Add icl_(un)set_bigjoiner_plane_links, to make it more clear where
  links are made and broken.

[Intel-gfx] [PATCH v15 13/14] drm/i915: Add bigjoiner aware plane clipping checks

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

We need to look at hw.fb for the framebuffer, and add the translation
for the slave_plane_state. With these changes we set the correct
rectangle on the bigjoiner slave, and don't set incorrect
src/dst/visibility on the slave plane.

v2:
* Manual rebase (Manasi)

v3:
* hw.rotation instead of uapi.rotation (Ville)

[Intel-gfx] [PATCH v15 14/14] drm/i915: Add debugfs dumping for bigjoiner, v3.

[Manasi Navare]

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

Dump debugfs and planar links as well, this will make it easier to debug
when things go wrong.

v4:
* Rebase
Changes since v1:
- Report planar slaves as such, now that we have the plane_state switch.
Changes since v2:
- Rebase on top of the new plane format dumping
