If the SSPP cannot process the image even in multirect mode, then it will be rejected in dpu_plane_atomic_check_pipe(). Hence try using multirect for resolutions which cannot be processed by a single SSPP without exceeding the MDP clock limits. changes in v2: - use crtc_state's adjusted_mode instead of mode - fix the UBWC condition to check maxlinewidth Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov Tested-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c index 0be195f9149c..bf063e21e3dd 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c @@ -792,6 +792,8 @@ static int dpu_plane_atomic_check(struct drm_plane *plane, plane); int ret = 0, min_scale; struct dpu_plane *pdpu = to_dpu_plane(plane); + struct dpu_kms *kms = _dpu_plane_get_kms(&pdpu->base); + u64 max_mdp_clk_rate = kms->perf.max_core_clk_rate; struct dpu_plane_state *pstate = to_dpu_plane_state(new_plane_state); struct dpu_sw_pipe *pipe = &pstate->pipe; struct dpu_sw_pipe *r_pipe = &pstate->r_pipe; @@ -860,14 +862,16 @@ static int dpu_plane_atomic_check(struct drm_plane *plane, max_linewidth = pdpu->catalog->caps->max_linewidth; - if (drm_rect_width(&pipe_cfg->src_rect) > max_linewidth) { + if ((drm_rect_width(&pipe_cfg->src_rect) > max_linewidth) || + _dpu_plane_calc_clk(&crtc_state->adjusted_mode, pipe_cfg) > max_mdp_clk_rate) { /* * In parallel multirect case only the half of the usual width * is supported for tiled formats.
