The branch main has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=e38e04a0ba3fdcdc2f3238bf4d962f65fadf527f commit e38e04a0ba3fdcdc2f3238bf4d962f65fadf527f Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2025-09-22 17:08:25 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2025-09-23 17:08:36 +0000 arm64: Add more counter/timer registers These will be used to support the Enhanced Counter Virtualization Extensions: FEAT_ECV and FEAT_ECV_POFF. The former adds Self-Synchronized registers, and the latter adds support for an offset for the physical counter.
