This series adds support to use devcoredump for DPU driver. It introduces the msm_disp_snapshot module which assists in the capturing of register dumps during error scenarios. When a display related error happens, the msm_disp_snapshot module captures all the relevant register dumps along with the snapshot of the drm atomic state and triggers a devcoredump. changes in v4: - rename dpu_dbg to msm_disp_snapshot and move it to msm/disp - start using a list of blocks to store the hardware block information - cleanup block allocation and freeing logic to simplify it Abhinav Kumar (3): drm: allow drm_atomic_print_state() to accept any drm_printer drm/msm: add support to take dpu snapshot drm/msm: add disp snapshot points across dpu driver drivers/gpu/drm/drm_atomic.c | 28 +++- 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_encoder.c | 18 +- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 14 +- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys_vid.c | 8 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 61 +++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 5 + drivers/gpu/drm/msm/disp/msm_disp_snapshot.c | 161 ++++++++++++++++++ drivers/gpu/drm/msm/disp/msm_disp_snapshot.h | 167 +++++++++++++++++++ drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c | 181 +++++++++++++++++++++ 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 | 29 ++++ drivers/gpu/drm/msm/dp/dp_display.h | 1 + drivers/gpu/drm/msm/dsi/dsi.c | 5 + drivers/gpu/drm/msm/dsi/dsi.h | 4 + drivers/gpu/drm/msm/dsi/dsi_host.c | 19 +++ drivers/gpu/drm/msm/msm_drv.c | 29 +++- drivers/gpu/drm/msm/msm_drv.h | 2 + drivers/gpu/drm/selftests/test-drm_framebuffer.c | 1 + 23 files changed, 743 insertions(+), 18 deletions(-) create mode 100644 drivers/gpu/drm/msm/disp/msm_disp_snapshot.c create mode 100644 drivers/gpu/drm/msm/disp/msm_disp_snapshot.h create mode 100644 drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
