[PATCH v5 0/6] drm/atomic: track individual colorop updates

[PATCH v5 0/6] drm/atomic: track individual colorop updates

[Melissa Wen]

This series aims to track updates for each individual color operation,
allowing the driver to react accordingly.

- Patches 1 and 2 make colorop update process more consistent and
  optimized by only keeping colorop states from active color pipelines.

- Patches 3 and 4 make lut1d_interpolation and lut3d_interpolation
  colorops correctly behave as mutable, handling their changes via
  drm_colorop_state.

- Finally, patches 5 and 6 track colorop updates of a given plane color
  pipeline by setting plane `color_mgmt_changed` flag, similar to what
  is done for tracking CRTC color mgmt property changes with CRTC
  `color_mgmt_changed` flag. The flag also tracks when a different color
  pipeline is set to a given plane. That way, the driver can react
  accordingly and update their color blocks.

It also fixes shaper/3D LUT updates when changing night mode settings on
gamescope with a custom branch that supports `COLOR_PIPELINE`:

can set them via drm_atomic_colorop_set_property().

[PATCH v5 4/6] drm/colorop: make lut(1/3)d_interpolation mutable

As it's not immutable anymore, any changes should be handled by
drm_colorop_state. Move their enum and make it correctly behaves as
mutable.

[PATCH v5 5/6] drm/atomic: track individual colorop updates

[Melissa Wen]

As we do for CRTC color mgmt properties, use color_mgmt_changed flag to
track any value changes in the color pipeline of a given plane, so that
drivers can update color blocks as soon as plane color pipeline or
individual colorop values change.

[PATCH v5 6/6] drm/amd/display: use plane color_mgmt_changed to track colorop changes

[Melissa Wen]

Ensure the driver tracks changes in any colorop property of a plane
color pipeline by using the same mechanism of CRTC color management and
update plane color blocks when any colorop property changes. It fixes an
issue observed on gamescope settings for night mode which is done via
shaper/3D-LUT updates.
