drm/i915/cdclk: Relocate intel_plane_calc_min_cdclk() calls

2025-10-10T23:51:34Z

There's no reason to defer intel_plane_calc_min_cdclk() until intel_cdclk_atomic_check(). Just do this as part of intel_atomic_check_planes() (after we've added all the planes to the state that affect the per-plane min_cdclk calculation).

drm/i915/cdclk: Do intel_cdclk_update_crtc_min_cdclk() per-pipe

2025-10-10T23:51:18Z

Currently we call intel_cdclk_update_crtc_min_cdclk() per-plane. That is rather wasteful, and also won't account for any of the other per-pipe min_cdclk restrictions from intel_crtc_compute_min_cdclk(). Change the behaviour to do do the comparison per-crtc instead, and use the final min cdclk as computed by intel_crtc_compute_min_cdclk().

drm/i915: Nuke intel_plane_ggtt_offset()

2025-07-19T17:55:12Z

We don't really need the extra intel_plane_ggtt_offset() wrapper anymore. Get rid of it. v2: Deal with reuse_vma() hacks Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20250717171353.23090-3-ville.syrjala@linux.intel.com

drm/i915/plane: make intel_plane_atomic_check() static and rename

intel_plane_atomic_check() isn't used outside of intel_plane.c. Make it static. While at it, rename to vacate the name for subsequent changes.
