The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=6f50b73ee5c11253a35bb2787f2bef627079999d commit 6f50b73ee5c11253a35bb2787f2bef627079999d Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2022-07-06 17:30:03 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2022-07-06 17:32:21 +0000 libpmc: add armv8 pmu-event aliases These are all "standard microarchitectural events", which in theory are supported by every ARMv8 processor. In practice, it depends on the pmu-event definitions being complete and accurate, which they are not for every processor. Still, these aliases should be functional on the majority of systems.
