# IRQ subsystem

## Introduction

The IRQ subsystem contains all things related to interrupts management. 

## Overview

The IRQ subsystem manages the following elements:
- [TSS structure generation and loading](tss.md)
- [GDT generation for bootstrap and applications processors, and GDT loading](gdt.md)
- [IDT generation and loading](idt.md)
- [IRQ handlers](irq.md)
- [ISO registering and GSI abstractions](gsi.md)

Please note the following:
- this subsystem is only targeting the x86-64 architecture
- this subsystem should only be used after the full memory subsystem initialization
- all the assets generated by this subsystem is, for the moment, only useful for the task performed during the boot process
