Yeah. It is to fix bug in non virtual plane mode.

No, I suggest to add Fixes trailer and to move fixes to the top of the series. > > > > > > > > Signed-off-by: Jun Nie <jun.nie@linaro.org> > > > --- > > > drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 5 +++++ > > > 1 file changed, 5 insertions(+) > > > > > > diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c > > > index 904ebec1c8a18..898fc2937954e 100644 > > > --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c > > > +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c > > > @@ -1042,6 +1042,11 @@ static int dpu_plane_atomic_check(struct drm_plane *plane, > > > pipe->multirect_index = DPU_SSPP_RECT_0; > > > pipe->multirect_mode = DPU_SSPP_MULTIRECT_PARALLEL; > > > > > > + /* > > > + * Signifies that r_pipe is to be used if the width of the 2nd > > > + * pipe is not 0.

Share SSPP info for multi-rect case if virtual plane is not enabled. Otherwise, the 2nd half of DMA content is not displayed due to sspp pointer of r_pipe is null. Signed-off-by: Jun Nie <jun.nie@linaro.org> --- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 5 +++++ 1 file changed, 5 insertions(+)
