This repository contains the following submodules:
| Name | Arch| Description |
| --- | --- | --- |
| [x86_64::cpuid](src/x86_64/cpuid/) | x86_64 |Facilities to process CPUID information. |
| [x86_64::msr](src/x86_64/msr.rs) | x86_64 | Constants and functions for Model Specific Registers |
| [aarch64::gic](src/aarch64/gic) | aarch64 | Structs to manage GICv2/GICv3/ITS devices for ARM64 |
| [aarch64::regs](src/aarch64/regs.rs) | aarch64 | Constants and functions to configure and manage CPU registers |
