From ac11060c6d4959e2d4ceada037d2e1e1bfcf6645 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Wed, 10 Jun 2026 17:18:17 +0200 Subject: drm/amd/display: Handle struct drm_plane_state.ignore_damage_clips The mode-setting pipeline can disabled damage clippings for a commit by setting ignore_damage_clips in struct drm_plane_state. The commit will then do a full display update. Test the flag in DCN code and do a full update in DCN code if it has been set. Commit 35ed38d58257 ("drm: Allow drivers to indicate the damage helpers to ignore damage clips") introduced ignore_damage_clips to selectively ignore damage clipping in certain framebuffer changes. This driver does not do that, but DRM's damage iterator will soon rely on the flag. Therefore supporting it here as well make sense for consistency.
