Some information would help reviewing the patch :-) Also, could you mention in the cover letter for the next version if you will merge the whole series, or expect individual maintainers to pick up the relevant patches ? > --- > drivers/gpu/drm/rcar-du/rcar_du_kms.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/drivers/gpu/drm/rcar-du/rcar_du_kms.c b/drivers/gpu/drm/rcar-du/rcar_du_kms.c > index 72dda446355f..8d91140151cc 100644 > --- a/drivers/gpu/drm/rcar-du/rcar_du_kms.c > +++ b/drivers/gpu/drm/rcar-du/rcar_du_kms.c > @@ -441,6 +441,7 @@ static void rcar_du_atomic_commit_tail(struct drm_atomic_state *old_state) > struct drm_crtc_state *crtc_state; > struct drm_crtc *crtc; > unsigned int i; > + bool fence_cookie = dma_fence_begin_signalling(); > > /* > * Store RGB routing to DPAD0 and DPAD1, the hardware will be configured > @@ -467,6 +468,7 @@ static void rcar_du_atomic_commit_tail(struct drm_atomic_state *old_state) > drm_atomic_helper_commit_modeset_enables(dev, old_state); > > drm_atomic_helper_commit_hw_done(old_state); > + dma_fence_end_signalling(fence_cookie); > drm_atomic_helper_wait_for_flip_done(dev, old_state); > > drm_atomic_helper_cleanup_planes(dev, old_state); -- Regards, Laurent Pinchart _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
