This series adds support to use devcoredump for DPU driver. It introduces the dpu_dbg module which assists in the capturing of register dumps during error scenarios. When a display related error happens, the dpu_dbg module captures all the relevant register dumps along with the snapshot of the drm atomic state and triggers a devcoredump. Abhinav Kumar (4): drm: allow drm_atomic_print_state() to accept any drm_printer disp/msm/dpu: add support to dump dpu registers drm/msm: register the base address with dpu_dbg module drm/msm/dpu: add dpu_dbg points across dpu driver drivers/gpu/drm/drm_atomic.c | 17 +- drivers/gpu/drm/drm_atomic_uapi.c | 4 +- drivers/gpu/drm/drm_crtc_internal.h | 4 +- drivers/gpu/drm/msm/Makefile | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c | 316 ++++++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h | 273 +++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_dbg_util.c | 313 +++++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 12 +- .../drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 5 +- .../drm/msm/disp/dpu1/dpu_encoder_phys_vid.c | 5 +- .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 4 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c | 6 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dspp.c | 7 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_intf.c | 5 +- .../gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.c | 6 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_sspp.c | 8 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_top.c | 7 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 12 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 4 +- drivers/gpu/drm/msm/dp/dp_catalog.c | 12 + drivers/gpu/drm/msm/dp/dp_catalog.h | 4 + drivers/gpu/drm/msm/dp/dp_display.c | 2 + drivers/gpu/drm/msm/dsi/dsi_host.c | 10 +- drivers/gpu/drm/msm/msm_drv.c | 30 +- drivers/gpu/drm/msm/msm_drv.h | 3 +- 25 files changed, 1045 insertions(+), 26 deletions(-) create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.c create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_dbg.h create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_dbg_util.c -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
