I think it's better to split out your fixup and cc: stable it, since I think you'll hit the same error also just when shutting down a CRTC at runtime. Which is something compositors and fbcon tends to do. Then we could put your patch into -fixes, and my cleanup (which really isn't a fix) into -next. Sounds good? Adding the drm_crtc_wait_one_vblank has my r-b (if it's just the bugfix patch only). -Daniel > Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> > Cc: Vincent Abriou <vincent.abriou@st.com> > Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> > --- > drivers/gpu/drm/sti/sti_crtc.c | 2 ++ > drivers/gpu/drm/sti/sti_cursor.c | 10 +--------- > drivers/gpu/drm/sti/sti_drv.c | 6 +++--- > drivers/gpu/drm/sti/sti_gdp.c | 10 +--------- > drivers/gpu/drm/sti/sti_hqvdp.c | 10 +--------- > drivers/gpu/drm/sti/sti_tvout.c | 24 ------------------------ > 6 files changed, 8 insertions(+), 54 deletions(-) > > diff --git a/drivers/gpu/drm/sti/sti_crtc.c b/drivers/gpu/drm/sti/sti_crtc.c > index 5824e6aca8f4..61c2379fba87 100644 > --- a/drivers/gpu/drm/sti/sti_crtc.c > +++ b/drivers/gpu/drm/sti/sti_crtc.c > @@ -40,6 +40,8 @@ static void sti_crtc_atomic_disable(struct drm_crtc *crtc, > DRM_DEBUG_DRIVER("\n");

I have added more than drm_crtc_wait_one_vblank(), I also change the clean up for encoders and remove functions that becomes unneeded. sti driver is used on setup-box platform where nobody load/unload the driver. I could do a patch to use drm_crtc_wait_one_vblank(), wait for you patch to be apply and then do the additional clean up or merge everything in one shot with this version.

In the end up to you (but I think I pushed the _shutdown refactor already), but in general I think splitting the cleanup from the bugfixes is good practice. Also note that just doing a CRTC dpms off will hit this already, not just module unload. At least I'm pretty sure of that. That looks like something worth of backporting to stable kernels. -Daniel > > > > > Adding the drm_crtc_wait_one_vblank has my r-b (if it's just the > > bugfix patch only). > > -Daniel > > > > > Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> > > > Cc: Vincent Abriou <vincent.abriou@st.com> > > > Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> > > > --- > > > drivers/gpu/drm/sti/sti_crtc.c | 2 ++ > > > drivers/gpu/drm/sti/sti_cursor.c | 10 +--------- > > > drivers/gpu/drm/sti/sti_drv.c | 6 +++--- > > > drivers/gpu/drm/sti/sti_gdp.c | 10 +--------- > > > drivers/gpu/drm/sti/sti_hqvdp.c | 10 +--------- > > > drivers/gpu/drm/sti/sti_tvout.c | 24 ------------------------ > > > 6 files changed, 8 insertions(+), 54 deletions(-) > > > > > > diff --git a/drivers/gpu/drm/sti/sti_crtc.c b/drivers/gpu/drm/sti/sti_crtc.c > > > index 5824e6aca8f4..61c2379fba87 100644 > > > --- a/drivers/gpu/drm/sti/sti_crtc.c > > > +++ b/drivers/gpu/drm/sti/sti_crtc.c > > > @@ -40,6 +40,8 @@ static void sti_crtc_atomic_disable(struct drm_crtc *crtc, > > > DRM_DEBUG_DRIVER("\n");
