Enabling Interupts

Post by GhostSniper »

Before you tell me to RTFW, I have already but I don't fully understand how to enable interrupts. I have my basic kernel, inb, outb, and print functions. But in order to use the inb and outb I have have to enable interrupts correct? It would really be appreciated if someone could tell me how to enable interrupts 8)

Code: Select all

asm volatile ("sti");
It really is that simple.
If I had an OS, there would be a link here.

The sti instruction?

Incorrect. Port I/O has nothing to do with interrupts.
Some people are offended by the verifiable truth; such people tend to remain blissfully unencumbered by fact.
If you are one of these people, my posts may cause considerable discomfort. Read at your own risk.
