This includes: 1) Adjusting pclk_rate to account for compression 2) Fixing the word count calculation for DSC 3) Setting the DATA_COMPRESS bit when DSC is enabled With these changes (and the dependency below), DSC v1.2 should work over DSI in command mode. Note: Changes that add DSC v1.2 support for video mode will be posted with the DP support changes. Depends-on: "add DSC 1.2 dpu supports" [1] and "Introduce MSM-specific DSC helpers" [2] [1] https://patchwork.freedesktop.org/series/116789/ [2] https://patchwork.freedesktop.org/series/115833/ Signed-off-by: Jessica Zhang --- Changes in v2: - Changed pclk math to only divide hdisplay by compression ratio - Reworded word count TODO comment - Make DATA_COMPRESS an INTF flag - Read INTF_CFG2 before setting DATA_COMRPESS register - Reworded commit messages and cover letter for clarity - Link to v1: https://lore.kernel.org/r/20230405-add-dsc-support-v1-0-6bc6f03ae735@quicinc.com --- Jessica Zhang (4): drm/msm/dsi: Adjust pclk rate for compression drm/msm/dsi: Fix compressed word count calculation drm/msm/dpu: Add DPU_INTF_DATA_COMPRESS feature flag drm/msm/dpu: Set DATA_COMPRESS for command mode .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 3 +++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 2 ++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_intf.c | 11 +++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_intf.h | 2 ++ drivers/gpu/drm/msm/dsi/dsi_host.c | 26 +++++++++++++++++----- 6 files changed, 40 insertions(+), 6 deletions(-) --- base-commit: 70e08302e024bfac485b12972099237f7f39d829 change-id: 20230405-add-dsc-support-fe130ba49841 Best regards,
