2025-12-11drm/i915/display: Detect AuxCCS support via display parent interfaceTvrtko Ursulin-0/+3
Whether AuxCCS can be properly supported depends on the support both from the display side and non-display side of the driver. Let us therefore allow for the non-display part to be queried via the display parent interface. The new interface replaces the HAS_AUX_CCS macro and we also remove the FIXME from skl_universal_plane_create since now the xe will not advertise the AuxCCS caps to start with so they do not need to be removed after enumeration. Also, by removing this build specific FIXME we come a step closer to fully de-coupling display and non-display. The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is still required for determining the need for PLANE_AUX_DIST programming.

Let's gradually start calling i915 and xe parent, or core, drivers from display via function pointers passed at display probe. Going forward, the struct intel_display_parent_interface is expected to include const pointers to sub-structs by functionality, for example: struct intel_display_rpm { struct ref_tracker *(*get)(struct drm_device *drm); /* ... */ }; struct intel_display_parent_interface { /* ... */ const struct intel_display_rpm *rpm; }; This is a baby step towards not building display as part of both i915 and xe drivers, but rather making it an independent driver interfacing with the two. v3: useless include additions dropped v2: unrelated include removal dropped Cc: Jouni Högander <jouni.hogander@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Link: https://patch.msgid.link/20251030202836.1815680-2-jouni.hogander@intel.com
