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
