This series improves our legacy serial support to add the ability to use MMIO based serial ports on x86 and to use ACPI's SPCR to automatically configure the default port.
An MMIO serial port can be specified explicitely using the "mmio," prefix for the --port argument to the 'serial' command, the register access size can also be specified via a suffix, and when 'serial' is used without arguments, it will try to use an ACPI SPCR entry (if any) to add the default port and configure it appropriately (speed, parity etc...) _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
