[PATCH] Support multiple USB HID keyboards/mice
by Daniel Khodabakhsh 07 Jan '25

07 Jan '25

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 v2 1/4] add debug when we set pci_pad_mem64

[PATCH] vgabios: Fix generating modes list for static_functionality
by Steven Price 25 Oct '24

25 Oct '24

Accessing the data in the vga_modes array requires using GET_GLOBAL(), and the bits set in the bit array should correspond to the modes, not the indexes in vga_modes. With this change the modes calculated matches the expected value of 0xfe0ff.
