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

From the core PMU' perspective, the Lunar Lake and Arrow Lake are the
same, which 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 details for the above new features can be found in the Intel
Architecture Instruction Set Extensions and Future Features (052).
https://cdrdv2.intel.com/v1/dl/getContent/671368

The counters may not be continuous anymore. Patch 1-2 converts the max
number of counters to a mask of counters. The change is a generic change
which impacts all X86 platforms.

Patch 3-4 supports all the legacy features on LNL and ARL.

Patch 5-7 supports the new Architectural performance monitoring V6.

Patch 8-11 supports the new PEBS format V6.

Patch 12 supports the new RDPMC metrics clear mode.
