The branch stable/14 has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=196bb0e152cf2d3a0ba61bda8a2d09c8107a809a commit 196bb0e152cf2d3a0ba61bda8a2d09c8107a809a Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2023-06-19 22:32:22 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2023-09-11 19:19:58 +0000 libpmc: make pmc_pmu_pmcallocate() machine-independent Have it call the platform-dependent version. For better layering, move the reset logic inside the new function. This is mainly to facilitate an upcoming change.
