[PATCH V2 00/13] intel_pmc: Add telemetry API to read counters

[David E. Box]

On newer Intel silicon, more IP counters are being added in Intel Platform
Monitoring Technology (PMT) telemetry spaces hosted in MMIO.  There is a
need for the intel_pmc_core driver and other drivers to access PMT hosted
telemetry in the kernel using an API. This patchset adds driver APIs to
allow registering and reading telemetry entries. It makes changes to the
intel_pmc_core driver to use these interfaces to access the low power mode
counters that are now exclusively available from PMT.

David E. Box (8):
  platform/x86/intel/vsec: Move structures to header
  platform/x86/intel/vsec: remove platform_info from vsec device
    structure
  platform/x86/intel/vsec: Add base address field
  platform/x86/intel/pmt: Add header to struct intel_pmt_entry
  platform/x86/intel/pmt: telemetry: Export API to read telemetry
  platform/x86/intel/pmc: Split pmc_core_ssram_get_pmc()
  platform/x86/intel/pmc: Find and register PMC telemetry entries
  platform/x86/intel/pmc: Add debug attribute for Die C6 counter

Gayatri Kammela (1):
  platform/x86/intel/vsec: Add intel_vsec_register

Rajvi Jingar (1):
  platform/x86/intel/pmc: Display LPM requirements for multiple PMCs

Xi Pardee (3):
  platform/x86:intel/pmc: Call pmc_get_low_power_modes from platform
    init
  platform/x86/intel/pmc: Retrieve LPM information using Intel PMT
  platform/x86/intel/pmc: Read low power mode requirements for MTL-M and
    MTL-P
