The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=2f51074c90ad28a9cc7715f5f9c4e9323609ab1b commit 2f51074c90ad28a9cc7715f5f9c4e9323609ab1b Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2025-01-23 23:27:57 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2025-01-23 23:27:57 +0000 riscv nexus: Remove support for I/O port resources RISC-V 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.
