I forgot the port

const
BOCHS_DEBUG_PORT = $e9;

Setting OutByteToPort() to stdcall didn't help at all. And I still don't get interrupt messages when CPU debugging is enabled.

[edit] I figured out how to get messages when interrupts fire. This is the last part:

Code: Select all

00012820490d[CPU  ] interrupt(): vector = 16, INT = 1, EXT = 0
00012820670d[CPU  ] interrupt(): vector = 16, INT = 1, EXT = 0

00012870058d[CPU  ] int_trap_gate286(): INTERRUPT TO SAME PRIVILEGE

Before that is just endless int 16's. Can anyone help me with this, cause it should call the legitimate ISRs in those spots, right?[/edit]

well, the question is now where do you have int 8 generated. Probably the best for you would be to have trace-on from your bootloader.

e.g., using a debugable bochs:

break 0x7c00
c
trace-on
c

Just by the look of it, int16 is int 0x10, so a video bios call. The int8 is the timer interrupt, irq0. You somehow call int 0x1C and 0x13 too, but that's in software.

What part is not normal?

Or place a halt instruction before you enable interrupts and then enable trace and then continue.
Then you can see what the cpu does after you enable interrupts.

Code: Select all

   bwritestr('KERNEL DEBUG MSG: HLT IS GOING TO BE EXECUTED!');
   asm
      hlt
   end;
   ksti();

Thanks, I've got the interrupts thing pretty much figured out it would seem. Or at least, I'm getting another error that seems to have nothing to do with interrupts.
