Loading a libpayload based payload like coreinfo or FILO from SeaBIOS or
GRUB pressing keys does not give the expected results.
For example, pressing F1 gives the character 24 translated to scan code
6a. ESC for example 43 (111) in coreinfo loaded from SeaBIOS on QEMU
Q35.
The problem is not reproducible using the payload directly, that means
without SeaBIOS or GRUB. The problem seems to be, that those have already
initialized the PS/2 controller and AT keyboard.
Comparing it with coreboot’s PS/2 keyboard code, the keyboard needs to
be reset. That seems to fix the issue, when the keyboard was initialized
before.
TEST=Build coreboot for QEMU Q35 with SeaBIOS, and coreinfo as secondary
payload. Run
qemu-system-i386 -M q35 -L /dev/shm -bios build/coreboot.rom -serial stdio
press 3 to select the coreinfo payload, and verify that the keys F1 and
F2 are working.
Same with coreinfo loaded from GRUB on the ASRock E350M1.
