Loading IDT ISR's triple faults?!?!?

[DixiumOS]

I'm trying to load the IDT.

However, when i try to load the IDT ISR's, it triple faults for whatever reason (suprisingly it doesn't at lidt, it does at adding the IDT ISR's).

Code at https://github.com/NunoLava1998/DixiumO ... rupt/idt.c (look at addisrfunctions)

How would i make this not triple fault?

You fix what is wrong with the code.

Listing every mistake that you make (and listing the same mistake time after time) makes you look like an incompetent fool.

I don't list every mistake i make.
Besides, you normally just argue.

Nuno, what exactly do you think the following does

Code: Select all

(unsigned)isr0()

given

Code: Select all

int isr0() {
	__asm__ volatile ("iret");
	return 0;
}

?

I'm fed up with trying to help you as you have proven to be terminally incapable of learning.

If you aren't posting every mistake that you make then the mind boggles as to what the ones that you don't post are.

Wait, you mean as long as the compiler doesn't complain he can't just use a random combination of symbols and expect his code to work?

Seriously, if you don't understand what you are doing, how can you expect to explain it to a computer?

Remember all those "bugs" in the tutorial you "fixed"?

The tutorial was right and your "fixes" are wrong.


More specifically, this code from the tutorial is right:

Code: Select all

idt_set_gate(0, (unsigned)isr0, 0x08, 0x8E);

And this code you're using is wrong:

Code: Select all

idt_set_gate(0, (unsigned)isr0(), 0x08, 0x8E);

You can't write an OS unless you know the difference between those two lines of code.

Octocontrabass, stop being being like that. You are really not helping. Now his understanding is "oops, I added some extra parantheses, that was an easy fix" and will move on to the next thing to flood the forum with. He's supposed to try to understand something for once. On IRC he really showed that he doesn't even understand how variables work so if you stop pointing fixes out, he will be forced to get himself out of trouble.

[Octocontrabass]

Sorry.

I'm just really annoyed by all these inane threads. I think I'll take a break for a while.

That's called APL

[DixiumOS]

Yeah, somehow that made it triple fault.

Finally i'm out of this hell called loading the GDT and IDT and now can continue.

[alexfru]

O rly?

Hi,

Finally i'm out of this hell called loading the GDT and IDT and now can continue.

The best thing to do now is to learn C.

Oh, good. The simplest part is done. Now you can continue getting stuck at the very next thing.

[iansjack]

I'm predicting the very next thing is that (for no reason whatsoever) it triple-faults when an interrupt is fired. Just a hunch.
