[PATCH v5 0/6] Add get-error-counter and clear-error-counter support for CRI

[Riana Tauro <riana.tauro@intel.com>]

Define request/response structures and helper functions to query system
controller to get/clear counter values for CRI.

Integrate get-error-counter with xe_drm_ras.

Usage:

Query all error counters using ynl

$ sudo ynl --family drm_ras --dump get-error-counter --json \
'{"node-id":0}'
[{'error-id': 1, 'error-name': 'core-compute', 'error-value': 0},
 {'error-id': 2, 'error-name': 'soc-internal', 'error-value': 0},
 {'error-id': 3, 'error-name': 'device-memory', 'error-value': 0},
 {'error-id': 4, 'error-name': 'pcie', 'error-value': 0},
 {'error-id': 5, 'error-name': 'fabric', 'error-value': 0}]

Query single error counter using ynl

$ sudo ynl --family drm_ras  --do get-error-counter --json \
  '{"node-id":1, "error-id":1}'
{'error-id': 1, 'error-name': 'core-compute', 'error-value': 2}

Clear counter using ynl

$ sudo ynl --family drm_ras  --do clear-error-counter --json '\
{"node-id":1, "error-id":1}'
None

Rev2: add helper for clear counter
      separate get error counter for other usecases
      move commands to sysctrl layer

Rev3: integrate clear-error-counter with drm_ras
      use drm_ras flag
      move drm_ras registration to ras init flow

Rev4: rebase

Riana Tauro (6):
  drm/xe/uapi: Add additional error components to xe drm_ras
  drm/xe/xe_ras: Add support to get error counter in CRI
  drm/xe/xe_ras: Add helper to clear error counter
  drm/xe/xe_drm_ras: Wire get-error-counter and clear-error-counter
    support for CRI
  drm/xe/xe_ras: Move xe drm_ras registration
  drm/xe/xe_ras: Control xe drm_ras registration with a flag
