It would be a "vm-wide syscall". You can also do that on x86 (through
KVM_IRQ_LINE).
I really do like the ioctl model

Why? For the HPET timer register for example, we could have a simple MMIO hook
that says
on_read:
return read_current_time() - shared_page.offset;
on_write:
handle_in_user_space();
For IDE, it would be as simple as
register_pio
