[PATCH 0/4] Add devcoredump support for DPU

Abhinav Kumar
2020-10-22T05:03:06Z

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
