The branch main has been updated by andrew: URL: https://cgit.FreeBSD.org/src/commit/?id=ee2642678a2ca1cb968fcb2795496bc56eacbe7b commit ee2642678a2ca1cb968fcb2795496bc56eacbe7b Author: Kajetan Puchalski <kajetan.puchalski@arm.com> AuthorDate: 2026-07-06 14:18:19 +0000 Commit: Andrew Turner <andrew@FreeBSD.org> CommitDate: 2026-07-06 15:18:30 +0000 arm64/vmm: Move host-side EL2 regs into sys_regs Move EL2 host registers that are not visible to the guest into hypctx->sys_regs. Prefix them with HOST_ to distinguish from EL2 registers which are part of the guest's own state (e.g. in VNCR).
