Currently, this is defined and used within the writeback's physical encoder layer however, the function can be modified to be used to setup the CDM block even for non-writeback interfaces. Until those modifications are planned and made, keep it local to writeback. changes in v3: - call bind_pingpong_blk() directly as disable() is dropped - add dpu_csc10_rgb2yuv_601l to dpu_hw_util.h and use it - fix kbot error on the function doc - document that dpu_encoder_helper_phys_setup_cdm() doesn't handle DPU_CHROMA_H1V2 changes in v2: - add the RGB2YUV CSC matrix to dpu util as needed by CDM - use dpu_hw_get_csc_cfg() to get and program CSC - drop usage of setup_csc_data() and setup_cdwn() cdm ops as they both have been merged into enable() - drop reduntant hw_cdm and hw_pp checks Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202312102149.qmbCdsg2-lkp@intel.com/ Signed-off-by: Abhinav Kumar Reviewed-by: Dmitry Baryshkov --- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h | 6 ++ .../drm/msm/disp/dpu1/dpu_encoder_phys_wb.c | 93 ++++++++++++++++++- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_util.h | 14 +++ 3 files changed, 112 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h index e2934a6702d1..bdb89cbbcfb8 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h @@ -14,8 +14,10 @@ #include "dpu_hw_intf.h" #include "dpu_hw_wb.h" #include "dpu_hw_pingpong.h" +#include "dpu_hw_cdm.h" #include "dpu_hw_ctl.h" #include "dpu_hw_top.h" +#include "dpu_hw_util.h" #include "dpu_encoder.h" #include "dpu_crtc.h" @@ -150,6 +152,7 @@ enum dpu_intr_idx { * @hw_pp: Hardware interface to the ping pong registers * @hw_intf: Hardware interface to the intf registers * @hw_wb: Hardware interface to the wb registers + * @hw_cdm: Hardware interface to the CDM registers * @dpu_kms: Pointer to the dpu_kms top level * @cached_mode: DRM mode cached at mode_set time, acted on in enable * @enabled: Whether the encoder has enabled and running a mode @@ -178,6 +181,7 @@ struct dpu_encoder_phys { struct dpu_hw_pingpong *hw_pp; struct dpu_hw_intf *hw_intf; struct dpu_hw_wb *hw_wb; + struct dpu_hw_cdm *hw_cdm; struct dpu_kms *dpu_kms; struct drm_display_mode cached_mode; enum dpu_enc_split_role split_role; @@ -207,6 +211,7 @@ static inline int dpu_encoder_phys_inc_pending(struct dpu_encoder_phys *phys) * @wbirq_refcount: Reference count of writeback interrupt * @wb_done_timeout_cnt: number of wb done irq timeout errors * @wb_cfg: writeback block config to store fb related details + * @cdm_cfg: cdm block config needed to store writeback block's CDM configuration * @wb_conn: backpointer to writeback connector * @wb_job: backpointer to current writeback job * @dest: dpu buffer layout for current writeback output buffer @@ -216,6 +221,7 @@ struct dpu_encoder_phys_wb { atomic_t wbirq_refcount; int wb_done_timeout_cnt; struct dpu_hw_wb_cfg wb_cfg; + struct dpu_hw_cdm_cfg cdm_cfg; struct drm_writeback_connector *wb_conn; struct drm_writeback_job *wb_job; struct dpu_hw_fmt_layout dest; diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c index f1b63dd9293c..3e5dbaa9c896 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c @@ -259,6 +259,96 @@ static void dpu_encoder_phys_wb_setup_ctl(struct dpu_encoder_phys *phys_enc) } } +/** + * dpu_encoder_helper_phys_setup_cdm - setup chroma down sampling block + * This API does not handle DPU_CHROMA_H1V2. + * @phys_enc:Pointer to physical encoder + */ +static void dpu_encoder_helper_phys_setup_cdm(struct dpu_encoder_phys *phys_enc) +{ + struct dpu_hw_cdm *hw_cdm; + struct dpu_hw_cdm_cfg *cdm_cfg; + struct dpu_hw_pingpong *hw_pp; + struct dpu_encoder_phys_wb *wb_enc; + const struct msm_format *format; + const struct dpu_format *dpu_fmt; + struct drm_writeback_job *wb_job; + int ret; + + if (!phys_enc) + return; + + wb_enc = to_dpu_encoder_phys_wb(phys_enc); + cdm_cfg = &wb_enc->cdm_cfg; + hw_pp = phys_enc->hw_pp; + hw_cdm = phys_enc->hw_cdm; + wb_job = wb_enc->wb_job; + + format = msm_framebuffer_format(wb_enc->wb_job->fb); + dpu_fmt = dpu_get_dpu_format_ext(format->pixel_format, wb_job->fb->modifier); + + if (!hw_cdm) + return; + + if (!DPU_FORMAT_IS_YUV(dpu_fmt)) { + DPU_DEBUG("[enc:%d] cdm_disable fmt:%x\n", DRMID(phys_enc->parent), + dpu_fmt->base.pixel_format); + if (hw_cdm->ops.bind_pingpong_blk) + hw_cdm->ops.bind_pingpong_blk(hw_cdm, PINGPONG_NONE); + + return; + } + + memset(cdm_cfg, 0, sizeof(struct dpu_hw_cdm_cfg)); + + cdm_cfg->output_width = wb_job->fb->width; + cdm_cfg->output_height = wb_job->fb->height; + cdm_cfg->output_fmt = dpu_fmt; + cdm_cfg->output_type = CDM_CDWN_OUTPUT_WB; + cdm_cfg->output_bit_depth = DPU_FORMAT_IS_DX(dpu_fmt) ?
