drm/rect: Add drm_rect_overlap()

2024-08-23T14:47:56+00:00

Check if two rectangles overlap. It's a bit similar to drm_rect_intersect() but this won't modify the rectangle. Simplifies a bit drm_panic. Signed-off-by: Jocelyn Falempe Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20240822073852.562286-3-jfalempe@redhat.com

drm/plane: remove drm_helper_get_plane_damage_clips

2021-07-27T10:21:22+00:00

It's not used. Drivers should instead use the helpers anyway. Currently both vbox and i915 hand-roll this and it's not the greatest. vbox looks buggy, and i915 does a bit much that helpers would take care of I think. Also improve the kerneldocs while we're at it.

drm: Add function to convert rect in 16.16 fixed format to regular format

2021-01-05T13:32:52+00:00

Much more clear to read one function call than four lines doing this conversion. v7: - function renamed - calculating width and height before truncate - inlined v10: - renamed parameters from source and destination to src and dst to match sister functions Cc: Ville Syrjälä Cc: dri-devel@lists.freedesktop.org Cc: Gwan-gyeong Mun Reviewed-by: Gwan-gyeong Mun Signed-off-by: José Roberto de Souza Link: https://patchwork.freedesktop.org/patch/msgid/20210104205654.238928-1-jose.souza@intel.com

drm/selftests: Add drm_rect selftests

2019-11-28T11:33:43+00:00

Add selftests for drm_rect. A few basic ones for clipped and unclipped cases, and a few special ones for specific bugs we had in the code. I'm too lazy to think of more corner cases to check at this time. Maybe later.
