Handle hardware interrupts #1

Closed mayant15 closed 3 years ago

mayant15 commented 3 years ago

Problem:

The kernel doesn't handle hardware interrupts
Some IRQs are mapped by default to positions in the IDT that are already taken, which calls wrong ISRs.

Proposed Solution:

Hardware interrupts are handled through calls made in response to IRQs. These should be implemented just like existing ISRs for exceptions.
Tell the PIC to remap IRQs based on the current IDT structure.
