This series enables this for Qualcomm msm driver. This was tested on Google Pixel3 phone which use LGE SW43408 panel. The changes include DSC data and hardware block enabling for DPU1 then support in encoder. We also add support in DSI and introduce required topology changes. In order for panel to set the DSC parameters we add dsc in drm_panel and set it from the msm driver. We still have dsc as a globabl entity. I think while doing DP + DSC we should be able to update it, right now comprehending the requirements are bit difficult. Complete changes which enable this for Pixel3 along with panel driver (not part of this series) and DT changes can be found at: git.linaro.org/people/vinod.koul/kernel.git pixel/dsc_v4 Comments welcome! Changes since v3: - Merge changes from Dmitry to have dsc per encoder instance - add warning for dsc and mode3d enabled together - set dsc in dpu_encoder_phys_vid as well - remove dsc hardcoded mask - use devm_kzalloc for memory allocation for dsc Changes since v2: - Fix comments by Dimitry except the dsc being global. - Move RM patch later for dependency on topology now - Add patch for mode valid callback for dsi_mgr - Add missing structure documentation patch - Fix errors in mode_3d changes - Rebase on v5.16-rc1 and test Changes since v1: - Fix various issues spotted by kbuildbot - Rebase to v5.15-rc3 - Remove unused fields and duplicate defines - Enable DSC blocks only when DSC is enabled - remove sdm845 feature mask, use 0 - Check for DSC in hw_ctl Changes since RFC: - Drop the DT binding patch as we derive the configuration from panel - Drop the drm api patch as we no longer need it (use pps drm api) - Fix comments raised by Dimitry - Add dsc parameters calculation from downstream Vinod Koul (13): drm/msm/dsi: add support for dsc data drm/msm/dsi: Pass DSC params to drm_panel drm/msm/disp/dpu1: Add support for DSC drm/msm/disp/dpu1: Add support for DSC in pingpong block drm/msm/disp/dpu1: Add DSC for SDM845 to hw_catalog drm/msm/disp/dpu1: Add DSC support in hw_ctl drm/msm/disp/dpu1: Add support for DSC in encoder drm/msm/disp/dpu1: Don't use DSC with mode_3d drm/msm: Add missing structure documentation drm/msm/disp/dpu1: Add support for DSC in topology drm/msm/disp/dpu1: Add DSC support in RM drm/msm/dsi: add mode valid callback for dsi_mgr drm/msm/dsi: Add support for DSC configuration drivers/gpu/drm/msm/Makefile | 1 + drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 177 ++++++++++- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h | 8 + .../drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 4 + .../drm/msm/disp/dpu1/dpu_encoder_phys_vid.c | 4 + .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 20 ++ .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 13 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c | 18 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.h | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.c | 210 +++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.h | 77 +++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_mdss.h | 13 + .../gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.c | 32 ++ .../gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.h | 14 + drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 1 + drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c | 56 ++++ drivers/gpu/drm/msm/disp/dpu1/dpu_rm.h | 1 + drivers/gpu/drm/msm/dsi/dsi.c | 5 + drivers/gpu/drm/msm/dsi/dsi.h | 3 + drivers/gpu/drm/msm/dsi/dsi.xml.h | 10 + drivers/gpu/drm/msm/dsi/dsi_host.c | 289 +++++++++++++++++- drivers/gpu/drm/msm/dsi/dsi_manager.c | 12 + drivers/gpu/drm/msm/msm_drv.h | 26 ++ include/drm/drm_panel.h | 7 + 25 files changed, 1001 insertions(+), 4 deletions(-) create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.c create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.h
