Subject: [PATCH V2 0/3] powercap: Introduce TPMI RAPL PMU support
Date: Mon,  8 Apr 2024 11:51:38 +0800

RAPL energy counter MSRs are exposed via perf PMU. But this is done by
separate code which is not part of RAPL framework, and it cannot be
reused by other RAPL Interface drivers like TPMI RAPL.

Introduce two new APIs for PMU support in RAPL framework. This allows
TPMI RAPL PMU support and also makes it possible for future cleanups of
MSR RAPL PMU code.

Changes since V1:
- remove the MSR RAPL PMU conversion because it is a separate work that
  can be done later.
- instead of using a flag to indicate the need of PMU support, introduce
  two APIs for the RAPL Interface driver to invoke explicitly.
- minor code/comments/changelog improvements.

thanks,
rui
