Subject: [PATCH v1 22/37] perf vendor events: Add lunarlake counter information
Add counter information necessary for optimizing event grouping the
perf tool.
The most recent RFC patch set using this information:
https://lore.kernel.org/lkml/20240412210756.309828-1-weilin.wang@intel.com/
The information was added in:
https://github.com/intel/perfmon/commit/475892a9690cb048949e593fe39cee65cd4765e1
and later patches.
