Subject: [PATCH 00/12] perf core PMU support for Sapphire Rapids

From: Kan Liang <kan.liang@...ux.intel.com>

Intel Sapphire Rapids server is the successor of the Intel Ice Lake
server. The enabling code is based on Ice Lake, but there are several
new features introduced.
- The event encoding is changed and simplified.
- A new Precise Distribution (PDist) facility.
- Two new data source fields, data block & address block, are added in
  the PEBS Memory Info Record for the load latency event.
- A new store Latency facility is introduced.
- The layout of access latency field of PEBS Memory Info Record has been
  changed. Two latency, instruction latency and cache access latency are
  recorded. To support the new latency fields, a new sample type,
  PERF_SAMPLE_WEIGHT_EXT, is introduced.
- Extends the PERF_METRICS MSR to feature TMA method level 2 metrics.

Besides the Sapphire Rapids specific features, the CPUID 10.ECX
extension is also supported, which is available for all platforms with
Architectural Performance Monitoring Version 5.

The full description for the SPR features can be found at Intel
Architecture Instruction Set Extensions and Future Features Programming
Reference, 319433-041 (and later).

Both kernel and perf tool patches are included in the V1.
