Subject: [PATCH v3 06/46] perf vendor events intel: Add alderlake metric constraints
Previously these constraints were disabled as they contained topdown
events. Since:
https://lore.kernel.org/all/20230312021543.3060328-9-irogers@google.com/
the topdown events are correctly grouped even if no group exists.
This change was created by PR:
https://github.com/intel/perfmon/pull/71
Signed-off-by: Ian Rogers <irogers@...gle.com>
