perf/x86: Add Lunar Lake and Arrow Lake support
From PMU's perspective, Lunar Lake and Arrow Lake are similar to the
previous generation Meteor Lake. Both are hybrid platforms, with e-core
and p-core.
The key differences include:
- The e-core supports 3 new fixed counters
- The p-core supports an updated PEBS Data Source format
- More GP counters (Updated event constraint table)
- New Architectural performance monitoring V6
(New Perfmon MSRs aliasing, umask2, eq).
- New PEBS format V6 (Counters Snapshotting group)
- New RDPMC metrics clear mode
The legacy features, the 3 new fixed counters and updated event
constraint table are enabled in this patch.
The new PEBS data source format, the architectural performance
monitoring V6, the PEBS format V6, and the new RDPMC metrics clear mode
are supported in the following patches.
