not even a switch case statement fixed it..

Code: Select all

void init_idt() {
  for (int i = 0; i < 256; i++) {
    // Register a default handler
    switch (i) {
    case 0xe:
      RegisterHandler(0xe, page_fault_handler);
      break;
    case 0x0:
      RegisterHandler(0, division_by_zero);
      break;
    default:
      RegisterHandler(i, default_handler);
      break;
    }

    // Setup an IDT entry for all the interrupt stubs
    kernel_interrupt_gate(i, stubs[i]);
  };

  idr.offset = (uint64_t)&IDT;
  idr.size = sizeof(IDT) - 1;

  idt_flush(&idr);
}

I made a pull request with the a fix to this bug. It was actually a small bug in the isr_stub handler themselves where the index into the idt_handlers table wasn't initialized properly so it would run the incorrect handlers.
