If queried for hw_intf objects during init, it will be NULL. Since hw_intf objects are needed only after encoder enable, defer the query to encoder enable which will be triggered after modeset. changes in v4: - Add details on commit text on why the change is needed (Sean) changes in v5: - Reword commit text on the usage of hw_intf objects (Sean) changes in v6: - none Signed-off-by: Jeykumar Sankaran Reviewed-by: Sean Paul --- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c | 53 +++++++--------------- 1 file changed, 16 insertions(+), 37 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c index ca0963c..6de13f4 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c @@ -462,7 +462,7 @@ static void dpu_encoder_phys_vid_enable(struct dpu_encoder_phys *phys_enc) { struct msm_drm_private *priv; struct dpu_encoder_phys_vid *vid_enc; - struct dpu_hw_intf *intf; + struct dpu_rm_hw_iter iter; struct dpu_hw_ctl *ctl; u32 flush_mask = 0; @@ -474,11 +474,20 @@ static void dpu_encoder_phys_vid_enable(struct dpu_encoder_phys *phys_enc) priv = phys_enc->parent->dev->dev_private; vid_enc = to_dpu_encoder_phys_vid(phys_enc); - intf = vid_enc->hw_intf; ctl = phys_enc->hw_ctl; - if (!vid_enc->hw_intf || !phys_enc->hw_ctl) { - DPU_ERROR("invalid hw_intf %d hw_ctl %d\n", - vid_enc->hw_intf != 0, phys_enc->hw_ctl != 0); + + dpu_rm_init_hw_iter(&iter, phys_enc->parent->base.id, DPU_HW_BLK_INTF); + while (dpu_rm_get_hw(&phys_enc->dpu_kms->rm, &iter)) { + struct dpu_hw_intf *hw_intf = (struct dpu_hw_intf *)iter.hw; + + if (hw_intf->idx == phys_enc->intf_idx) { + vid_enc->hw_intf = hw_intf; + break; + } + } + + if (!vid_enc->hw_intf) { + DPU_ERROR("hw_intf not assigned\n"); return; } @@ -500,7 +509,7 @@ static void dpu_encoder_phys_vid_enable(struct dpu_encoder_phys *phys_enc) !dpu_encoder_phys_vid_is_master(phys_enc)) goto skip_flush; - ctl->ops.get_bitmask_intf(ctl, &flush_mask, intf->idx); + ctl->ops.get_bitmask_intf(ctl, &flush_mask, vid_enc->hw_intf->idx); ctl->ops.update_pending_flush(ctl, flush_mask); skip_flush: @@ -531,22 +540,13 @@ static void dpu_encoder_phys_vid_get_hw_resources( struct dpu_encoder_hw_resources *hw_res, struct drm_connector_state *conn_state) { - struct dpu_encoder_phys_vid *vid_enc; - if (!phys_enc || !hw_res) { DPU_ERROR("invalid arg(s), enc %d hw_res %d conn_state %d\n", phys_enc != 0, hw_res != 0, conn_state != 0); return; } - vid_enc = to_dpu_encoder_phys_vid(phys_enc); - if (!vid_enc->hw_intf) { - DPU_ERROR("invalid arg(s), hw_intf\n"); - return; - } - - DPU_DEBUG_VIDENC(vid_enc, "\n"); - hw_res->intfs[vid_enc->hw_intf->idx - INTF_0] = INTF_MODE_VIDEO; + hw_res->intfs[phys_enc->intf_idx - INTF_0] = INTF_MODE_VIDEO; } static int _dpu_encoder_phys_vid_wait_for_vblank( @@ -781,7 +781,6 @@ struct dpu_encoder_phys *dpu_encoder_phys_vid_init( { struct dpu_encoder_phys *phys_enc = NULL; struct dpu_encoder_phys_vid *vid_enc = NULL; - struct dpu_rm_hw_iter iter; struct dpu_encoder_irq *irq; int i, ret = 0; @@ -801,26 +800,6 @@ struct dpu_encoder_phys *dpu_encoder_phys_vid_init( phys_enc->hw_mdptop = p->dpu_kms->hw_mdp; phys_enc->intf_idx = p->intf_idx; - /** - * hw_intf resource permanently assigned to this encoder - * Other resources allocated at atomic commit time by use case - */ - dpu_rm_init_hw_iter(&iter, 0, DPU_HW_BLK_INTF); - while (dpu_rm_get_hw(&p->dpu_kms->rm, &iter)) { - struct dpu_hw_intf *hw_intf = (struct dpu_hw_intf *)iter.hw; - - if (hw_intf->idx == p->intf_idx) { - vid_enc->hw_intf = hw_intf; - break; - } - } - - if (!vid_enc->hw_intf) { - ret = -EINVAL; - DPU_ERROR("failed to get hw_intf\n"); - goto fail; - } - DPU_DEBUG_VIDENC(vid_enc, "\n"); dpu_encoder_phys_vid_init_ops(&phys_enc->ops);
