Cant get hardware interrupts working

[moondeck]

So, i have set up the IDT and interrupts, i can receive software interrupts, but when i press a key on the keyboard nothing happens, and it should display "interrupt". What am i doing wrong?
Code is on Github, in the kernelio folder. the files are irq.c irq.asm and idt.c : https://github.com/m00nd3ck/hydrogen

Thanks,
moondeck

Command 0xAA disables the keyboard (among other side effects). You have to properly initialize the keyboard controller, which includes enabling the keyboard.

You also need to empty the keyboard controller's buffer after you receive an interrupt from it, or it won't send any more interrupts.

Okay, remember that in C, the name of an array is always a pointer to the base. For example:

Code: Select all

//instead of:
idtp.base = (int) &idt;

//do this! idt is itself a pointer
idtp.base = (int) idt;
