The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=9f4df9fc1ba8841a28584ed1323fc8cc9e54c9bc commit 9f4df9fc1ba8841a28584ed1323fc8cc9e54c9bc Author: Kevin Bowling <kbowling@FreeBSD.org> AuthorDate: 2026-08-06 06:43:47 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-08-08 11:57:28 +0000 amd_iommu: Honor disabled interrupt remapping Do not instantiate an interrupt-remapping context for a unit whose IRTE support is disabled. In that mode the caller must retain the ordinary interrupt path.
