That function doesnt account for the foll considerations: 1) How does it guarantee plane priority while allocation? smart dma planes need to be allocated in a priority order and that priority order decides which sspp does on the left rectangle and which one on the right. I am not seeing how that is enforced in this implementation. 2) Another condition to be taken into account is that if one rectangle of one SSPP is utilized for one display, the other rectangle of the SSPP cannot be used for another display. How is this guaranteed? Does the RM global state account for this? > Signed-off-by: Dmitry Baryshkov > --- > drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 18 +++- > drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 2 +- > drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 109 +++++++++++++--------- > drivers/gpu/drm/msm/disp/dpu1/dpu_plane.h | 29 +----- > 4 files changed, 86 insertions(+), 72 deletions(-) > > diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c > b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c > index 49bdd5953b9f..49bd9df387b8 100644 > --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c > +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c > @@ -892,7 +892,7 @@ static int dpu_crtc_atomic_check(struct drm_crtc > *crtc, > struct dpu_global_state *global_state = > dpu_kms_get_global_state(state); > > struct dpu_plane_state **pstates; > - struct dpu_plane_state *pstate; > + struct dpu_plane_state *pstate, *prev_plane_state; > > struct drm_plane_state *plane_state; > struct drm_plane *plane; > @@ -962,6 +962,7 @@ static int dpu_crtc_atomic_check(struct drm_crtc > *crtc, > } > > stage = DPU_STAGE_0; > + prev_plane_state = NULL; > for (i = 0; i <= max_zpos; i++) { > pstate = pstates[i]; > if (!pstate) > @@ -977,8 +978,6 @@ static int dpu_crtc_atomic_check(struct drm_crtc > *crtc, > > plane_state = &pstate->base; > > - dpu_plane_clear_multirect(plane_state); > - > dst = drm_plane_state_dest(plane_state); > if (!drm_rect_intersect(&dst, &crtc_rect)) { > DPU_ERROR("invalid vertical/horizontal destination\n"); > @@ -990,7 +989,7 @@ static int dpu_crtc_atomic_check(struct drm_crtc > *crtc, > } > > plane = pstate->base.plane; > - rc = dpu_plane_set_pipe(plane, pstate); > + rc = dpu_plane_set_pipe(plane, pstate, prev_plane_state); > if (rc) { > DPU_ERROR("%s: error setting pipe for %s\n", dpu_crtc->name, > plane->name); > goto end; > @@ -1002,6 +1001,17 @@ static int dpu_crtc_atomic_check(struct drm_crtc > *crtc, > goto end; > } > > + /* > + * If this plane was not selected for multirect, so we can try > + * using it together with the next pipe.
