This merged damage areas will be used for FBC dirty rect support in xe3 in the follow-up patch. Big thanks to Ville Syrjala for his contribuitions in shaping up of this series. v1: - Move damage_merged helper to cover bigjoiner case and use the correct plane state for damage find helper (Ville) - Damage handling code under HAS_FBC_DIRTY_RECT() so the the related part will be executed only for xe3+ - Changed dev_priv to i915 in one of the functions v2: - damage reported is stored in the plane state after coords adjustmentments irrespective of fbc dirty rect support. - Damage to be empty in case of plane not visible (Ville) - Handle fb could be NULL and plane not visible cases (Ville) Signed-off-by: Vinod Govindapillai --- .../gpu/drm/i915/display/intel_atomic_plane.c | 31 +++++++++++++ .../drm/i915/display/intel_display_types.h | 2 + .../drm/i915/display/skl_universal_plane.c | 46 ++++++++++++++++++- 3 files changed, 78 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_atomic_plane.c b/drivers/gpu/drm/i915/display/intel_atomic_plane.c index 8a49d87d9bd9..b4e94dd01173 100644 --- a/drivers/gpu/drm/i915/display/intel_atomic_plane.c +++ b/drivers/gpu/drm/i915/display/intel_atomic_plane.c @@ -36,6 +36,7 @@ #include #include +#include #include #include #include @@ -117,6 +118,7 @@ intel_plane_duplicate_state(struct drm_plane *plane) intel_state->ggtt_vma = NULL;
