| * | [spcr] Accept alternative type value for a 16550-compatible UART | Michael Brown | 2025-11-05 | 1 | -0/+1 |
| | | | | | | | | | | | | | Some systems (observed on an AWS EC2 m7i.metal-24xl instance in eu-south-2) use the newer "16550-compatible with parameters defined in Generic Address Structure" type value. (There does not appear to be any particular reason why the newer value needs to be used: the UART is still a standard 16550 with single-byte registers.) Accept this additional type value for a 16550-compatible UART. Signed-off-by: Michael Brown <mcb30@ipxe.org> | ||||
| * | [spcr] Add support for the ACPI Serial Port Console Redirection table | Michael Brown | 2025-11-05 | 1 | -0/+162 |
| The BIOS may provide an ACPI Serial Port Console Redirection (SPCR) table to describe the serial port to be used for early boot messages. Add support for parsing the SPCR and instantiating a 16550-based UART. We do not currently attempt to support other types of UART, since iPXE does not yet have drivers for other types.
