drm/{i915, xe}: pass struct drm_device instead of drm_device to ->alloc_obj

2025-12-22T13:09:23+00:00

The initial plane parent interface ->alloc_obj hook no longer needs the
crtc for anything. Pass struct drm_device instead.

drm/{i915, xe}: pass struct drm_plane_state instead of struct drm_crtc to ->setup

The initial plane parent interface ->setup hook no longer needs the crtc
for anything. Pass the struct drm_plane_state instead.

drm/{i915,xe}: deduplicate initial plane setup

2025-12-22T13:09:23+00:00

Deduplicate more of the identical parts of i915 and xe initial plane
setup. This lets us reduce the core dependency on display internals.

drm/{i915, xe}: deduplicate intel_alloc_initial_plane_obj() FB modifier checks

drm/i915: further deduplicate intel_find_initial_plane_obj()

2025-12-22T13:09:23+00:00

Move intel_reuse_initial_plane_obj() into common display code, and split
the ->find_obj hook into ->alloc_obj and ->setup hooks.

Return the struct drm_gem_object from ->alloc_obj in preparation for
moving more things to display.

drm/{i915, xe}: start deduplicating intel_find_initial_plane_obj() between i915 and xe

2025-12-22T13:09:22+00:00

Move some easy common parts to display. Initially, the
intel_find_initial_plane_obj() error path seems silly, but it'll be more
helpful this way for later changes.

drm/{i915, xe}: deduplicate plane_config_fini() between i915 and xe

2025-12-22T13:09:22+00:00

Move the common code to display. Retain empty xe_plane_config_fini() for
now, in case it's needed in the future.

drm/{i915, xe}: move initial plane calls to parent interface

2025-12-22T13:09:22+00:00

Add the initial plane handling functions to the display parent
interface. Add the call wrappers in dedicated intel_initial_plane.c
instead of intel_parent.c, as we'll be refactoring the calls heavily.
