The branch main has been updated by royger: URL: https://cgit.FreeBSD.org/src/commit/?id=1491fe8f864af5af37e83f1d12459905fb6097fd commit 1491fe8f864af5af37e83f1d12459905fb6097fd Author: Roger Pau Monné <royger@FreeBSD.org> AuthorDate: 2026-03-26 10:01:57 +0000 Commit: Roger Pau Monné <royger@FreeBSD.org> CommitDate: 2026-03-27 08:26:32 +0000 uart/pci: support 16550A PCI serial devices Expand the current check to also attach the ns8250 driver to devices reporting as 16550A. This has been tested to work on a real device. From an inspection of the code in the ns8250 driver it seems like it should support up to 16950A devices, but I don't have hardware to ensure that, hence be conservative with the change.
