The branch main has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=a4f0e93c514280bfd0ff3897e5171ec7bbe4796b commit a4f0e93c514280bfd0ff3897e5171ec7bbe4796b Author: Andrew Turner <andrew@FreeBSD.org> AuthorDate: 2026-02-03 17:14:44 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2026-02-03 17:14:44 +0000 arm64/vmm: Set and use the fine-grained traps Set the Fine-grained trap registers to trap any features we don't support. These are expected to be more useful when we support nested virtualisation, so for now just the base features and GICv3 are not trapped. As nested virtualisation will require VHE we only set the fine-grained trap registers when VHE is used.
