I was (still am) hoping to do a testing for this patch but when I dug out the series from the ML it looked like it has extra dependencies, so I was waiting for the dust to settle. Otherwise, LGTM.

I should all just apply I think, it's based on drm-tip. Branch with bunch of other random stuff is here: https://cgit.freedesktop.org/~danvet/drm/log/ If that doesn't cherry-pick cleanly I'm confused about something. -Daniel > > Best regards, > Liviu > > > > > Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> > > Cc: "James (Qian) Wang" <james.qian.wang@arm.com> > > Cc: Liviu Dudau <liviu.dudau@arm.com> > > Cc: Mihail Atanassov <mihail.atanassov@arm.com> > > --- > > drivers/gpu/drm/arm/malidp_drv.c | 3 +++ > > 1 file changed, 3 insertions(+) > > > > diff --git a/drivers/gpu/drm/arm/malidp_drv.c b/drivers/gpu/drm/arm/malidp_drv.c > > index 69fee05c256c..26e60401a8e1 100644 > > --- a/drivers/gpu/drm/arm/malidp_drv.c > > +++ b/drivers/gpu/drm/arm/malidp_drv.c > > @@ -234,6 +234,7 @@ static void malidp_atomic_commit_tail(struct drm_atomic_state *state) > > struct drm_crtc *crtc; > > struct drm_crtc_state *old_crtc_state; > > int i; > > + bool fence_cookie = dma_fence_begin_signalling(); > > > > pm_runtime_get_sync(drm->dev); > > > > @@ -260,6 +261,8 @@ static void malidp_atomic_commit_tail(struct drm_atomic_state *state) > > > > malidp_atomic_commit_hw_done(state); > > > > + dma_fence_end_signalling(fence_cookie); > > + > > pm_runtime_put(drm->dev); > > > > drm_atomic_helper_cleanup_planes(drm, state); > > -- > > 2.27.0 > > > > -- > ==================== > | I would like to | > | fix the world, | > | but they're not | > | giving me the | > \ source code! / > --------------- > ¯\_(ツ)_/¯

Again needs to be put right after the call to drm_atomic_helper_commit_hw_done(), since that's the last thing which can hold up a subsequent atomic commit. No surprises here.
