Separate DSC flush away from dpu_hw_ctl_intf_cfg_v1() by adding dpu_hw_ctl_update_pending_flush_dsc_v1() to handle both per-DSC engine and DSC flush bits at same time to make it consistent with the location of flush programming of other DPU sub-blocks. Changes in v10: -- rewording commit text -- pass ctl directly instead of dpu_enc to dsc_pipe_cfg() -- ctx->pending_dsc_flush_mask = 0; Changes in v11: -- add Fixes tag -- capitalize MERGE_3D, DSPP and DSC at struct dpu_hw_ctl_ops{} Changes in v12: -- move dsc parameter to next line at dpu_encoder_dsc_pipe_cfg() Signed-off-by: Kuogee Hsieh Reviewed-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 10 ++++++++-- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c | 23 +++++++++++++++++------ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.h | 11 +++++++++++ 3 files changed, 36 insertions(+), 8 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c index ffa6f04..7fca09e 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c @@ -1834,7 +1834,8 @@ dpu_encoder_dsc_initial_line_calc(struct drm_dsc_config *dsc, return DIV_ROUND_UP(total_pixels, dsc->slice_width);
