The branch main has been updated by mav: URL: https://cgit.FreeBSD.org/src/commit/?id=73b7b181e691ebbe8a0e411fd60f5003b51dc75d commit 73b7b181e691ebbe8a0e411fd60f5003b51dc75d Author: Alexander Motin <mav@FreeBSD.org> AuthorDate: 2022-05-30 23:58:40 +0000 Commit: Alexander Motin <mav@FreeBSD.org> CommitDate: 2022-05-31 00:05:15 +0000 libpmc: Disable hardcoding of Intel fixed counters.
