[PATCH v3 0/6] Support PMT features in Xe

[Michael J. Ruhl]

DG2 and Battlemage have the Intel Platform Monitoring Technology (PMT)
feature available, but not in the "standard" (pci endpoint) way.

Add support to the vsec and Xe drivers to allow access to the PMT space
for the DG2 and BMG devices.

The intel_vsec_register() function allows drivers to provide telemetry
header information (usually found at probe time), to allow the PMT
driver to probe the telemetry features.

Battlemage has a shared memory area (selected by index), so a callback
function is required to access the appropriate PMT data.

V2:
  Re-worked DG2 support patches using a base_adjust rather than a
  quirk.
  Updated GUID decode, for correct decode.
v3:
  Fixed a documentation issue for the pmt struct.

David E. Box (3):
  platform/x86/intel/vsec.h: Move to include/linux
  platform/x86/intel/vsec: Add PMT read callbacks
  platform/x86/intel/pmt: Use PMT callbacks

Michael J. Ruhl (3):
  drm/xe/vsec: Support BMG devices
  platform/x86/intel/pmt: Add support for PMT base adjust
  drm/xe/vsec: Add support for DG2
