The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=bf6c4ee6f0c8d0b9025207cde648427b749d8420 commit bf6c4ee6f0c8d0b9025207cde648427b749d8420 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2025-01-23 23:27:48 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2025-01-23 23:27:48 +0000 arm64 nexus: Remove support for I/O port resources arm64 doesn't natively support I/O port resources. PCI I/O port BARs are remapped to memory resources by PCI bridge drivers before the request is passed up to the nexus layer.
