This patch series adds CPER (Common Platform Error Record) logging support
for RAS errors reported by Intel Xe GPUs. CPER records are emitted through
a trace event.

v2:
   - Extended CPER logging to Uncorrectable errors and xe_ras_get_counter
     request
   - Log CPER records via xe_log SIGID infra 

v3:
  - Added the patches in incremental order (Raag)
  - Fixed Sashiko warnings which are applicable 

v4:
  - Split the patches further for incremental review (Raag)
  - Refactor info queue handling (Raag)
  - Fix applicable Sashiko warnings

v5:
  - Fixed v4 comments
  - Covered default paths in error handling flow
  - Moved info queue related patches at top
  - Added example logs
 
Badal Nilawar (13):
  drm/xe/cper: Add CPER reporting entry point for xe_log
  drm/xe/cper: Retrieve the error counter record for CPER reporting
  drm/xe/cper: Initialize Intel-specific section header
  drm/xe/cper: Construct CPER record for hardware errors
  drm/xe/cper: Log CPER records for aggregate counter retrieval
  drm/xe/cper: Emit cper record to trace buf
  drm/xe/xe_ras: Report device memory errors using SIGID
  drm/xe/xe_ras: Report core compute errors using SIGID
  drm/xe/xe_ras: Report soc internal errors using SIGID
  drm/xe/xe_ras: Report correctable errors using SIGID
  drm/xe/xe_ras: Report unknown errors using SIGID
  drm/xe/xe_ras: Add support to retrieve info queue data
  drm/xe/cper: Prepare Intel CPER info records
