Fix by setting -out-scale size as zero when the dst size is zero, similar to what is -done by drm_calc_scale(). This issue started with the introduction of -cursor ovelay mode that uses this function to assess cursor mode changes -via dm_crtc_get_cursor_mode() before checking plane state. - -Fixes: 1b04dcca4fb1 ("drm/amd/display: Introduce overlay cursor mode") -Link: https://gitlab.freedesktop.org/drm/amd/-/issues/3729 -Reported-by: Fabio Scaccabarozzi <> -Co-developed-by: Fabio Scaccabarozzi <> -Signed-off-by: Fabio Scaccabarozzi <> -Signed-off-by: Melissa Wen ---- - drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - -diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c -index 85f21db6ef24..2c795b867c1c 100644 ---- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c -+++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c -@@ -11124,8 +11124,8 @@ dm_get_plane_scale(struct drm_plane_state *plane_state, - int plane_src_w, plane_src_h; - - dm_get_oriented_plane_size(plane_state, &plane_src_w, &plane_src_h); -- *out_plane_scale_w = plane_state->crtc_w * 1000 / plane_src_w; -- *out_plane_scale_h = plane_state->crtc_h * 1000 / plane_src_h; -+ *out_plane_scale_w = plane_src_w ? plane_state->crtc_w * 1000 / plane_src_w : 0; -+ *out_plane_scale_h = plane_src_h ? plane_state->crtc_h * 1000 / plane_src_h : 0; - } - - /* --- -2.45.2 -
