Each 17 telem<x> directory has an associated telem file. This file 18 may be opened and mapped or read to access the telemetry space 19 of the device. The register layout of the telemetry space is 20 determined from an XML file that matches the PCI device id and 21 GUID for the device. 22 23What: /sys/class/intel_pmt/telem<x>/telem 24Date: October 2020 25KernelVersion: 5.10 26Contact: David Box <david.e.box@linux.intel.com> 27Description: 28 (RO) The telemetry data for this telemetry device.
