[PATCH v2 00/12] Generate CPER records for RAS and commit to CPER ring

[Xiang Liu]

This patch series generate RAS CPER records for UE/DE/CE/BP threshold exceed
event. SMU_TYPE_CE banks are combined into 1 CPER entry, they could be CEs or
DEs or both. UEs and BPs are encoded into separate CPER entries.

RAS CPER records for CEs will be generated only after CEs count been queried.

All records are committed to a pure software ring with a limit size, new records
will flush older records when overflow happened. User can access the records by
reading debugfs node, which is read-only.

  drm/amd/include: Add amd cper header
  drm/amdgpu: Introduce funcs for populating CPER
  drm/amdgpu: Include ACA error type in aca bank
  drm/amdgpu: Introduce funcs for generating cper record
  drm/amdgpu: Generate cper records

Tao Zhou (4):
  drm/amdgpu: add RAS CPER ring buffer
  drm/amdgpu: read CPER ring via debugfs
  drm/amdgpu: add data write function for CPER ring
  drm/amdgpu: add mutex lock for cper ring

Xiang Liu (3):
  drm/amdgpu: Get timestamp from system time
  drm/amdgpu: Commit CPER entry
  drm/amdgpu: Generate bad page threshold cper records
