Subject: [PATCH v1 18/22] perf vendor events: Update Sapphirerapids events/metrics
Update events from v1.23 to v1.25.
Update TMA metrics from 4.8 to 5.01.
Bring in the event updates v1.25:
https://github.com/intel/perfmon/commit/78d6273c546329052429e3a005491b58fbe1167b
https://github.com/intel/perfmon/commit/f069ed9d0b69b02d76d4b4c59dfc75b62bfb2254
The TMA 5.01 addition is from (with subsequent fixes):
https://github.com/intel/perfmon/commit/1d72913b2d938781fb28f3cc3507aaec5c22d782
Update uncore IIO events umask with the change:
https://github.com/intel/perfmon/commit/d78e8a166537c9ceab4f2e901dc96c53667a2174
which should address an issue originally raised by Michael Petlan:
Reported-by: Michael Petlan <mpetlan@...hat.com>
Closes: https://lore.kernel.org/all/alpine.LRH.2.20.2401300733310.11354@Diego/
