[PATCH] Support multiple USB HID keyboards/mice
by Daniel Khodabakhsh Jan. 7, 2025

Jan. 7, 2025

This change allows the use of multiple USB HID keyboards and mice. It's similar to the change by Stef van Os from this thread: https://mail.coreboot.org/hyperkitty/list/seabios@seabios.org/thread/O6Y4LU… however this new change uses the linked list approach instead of a fixed array. Tested on QEMU and an Asus KGPE-D16 with 2 keyboards and one mice

[PATCH] Add force-boot-menu runtime configuration
by Daniel Khodabakhsh Dec. 24, 2024

Dec. 24, 2024

This change adds a 'force-boot-menu' runtime configuration such that if a non-zero value is set and 'show-boot-menu' is also non-zero, SeaBIOS will show the boot menu without a timeout. This is similar to GRUB having a timeout set to '-1' and originally I wanted to implement it that way but the function to retrieve an integer retrieves an unsigned one so I thought this "boolean" configuration is a good way to implement it. Tested on ASUS KGPE-D16.
