Description 小笼包 intel_group 2024-02-03 18:29:05 UTC 
Description of problem:
The TPMI (Topology Aware Register and PM Capsule Interface) provides a
flexible, extendable and PCIe enumerable MMIO interface for PM features.
Intel RAPL (Running Average Power Limit) is one of the features that
benefit from this.
This RAPL TPMI Interface driver binds the RAPL auxiliary device created
by the TPMI enumeration driver and expose the RAPL control to userspace
via powercap sysfs class.
This change will backport TPMI RAPL driver support on Intel Birch
Stream (BHS) platforms (including GNR and SRF) to devel-5.10.
