Crate axcpu 

axcpu

This crate provides privileged instruction and structure abstractions for various CPU architectures. It is designed to implement the hardware abstraction layer of an operating system kernel.

Supported Architectures

• x86_64
• AArch64
• RISC-V
• LoongArch64

Modules

asm

Wrapper functions for assembly instructions.

init

Helper functions to initialize the CPU states on systems bootstrapping.

trap

Trap handling.

uspaceuspace

Structures and functions for user space.

Structs

ExtendedState

Extended state of a task, such as FP/SIMD states.

FxsaveArea

A 512-byte memory region for the FXSAVE/FXRSTOR instruction to save and restore the x87 FPU, MMX, XMM, and MXCSR registers.

TaskContext

Saved hardware states of a task.

TrapFrame

Saved registers when a trap (interrupt or exception) occurs.
