X86 architecture processor has an IDT to distribute the coming interrupts. I only found the default initialization of IDT in /src/arch/i386/lib/c_start.S. I thought that after device enumeration, the IDT also needs to be updated according to the enumeration result. Unfortunately, I can't find where the code is located. Who could give me a clue? Thank you in advance.
I don't think LB or FILO drives any hardware using interrupts, so no idt is needed.
Once Linux kicks in, it will set up everything it needs.
