Struct Vcpu 

pub struct Vcpu {
    pub iregs: IntRegisters,
    pub fpu: FpuContext,
    pub fpu_used: bool,
    pub vector: Option<Box<VectorContext>>,
    pub vector_used: bool,
    pc: u64,

}

Fields

iregs: IntRegisters

fpu: FpuContext

Floating-point register context (F/D extensions)

fpu_used: bool

Whether this task has ever used the FPU (F/D).

vector: Option<Box<VectorContext>>

Vector register context (V extension)

vector_used: bool

Whether this task has ever used the Vector extension (V).

pc: u64

asid: usize

mode: Mode

Implementations

impl Vcpu

pub fn new(mode: Mode) -> Self

pub fn set_asid(&mut self, asid: usize)

pub fn set_pc(&mut self, pc: u64)

pub fn get_pc(&self) -> u64

pub fn set_sp(&mut self, sp: usize)

pub fn get_mode(&self) -> Mode

pub fn reset_iregs(&mut self)

pub fn copy_iregs_to(&self, iregs: &mut IntRegisters)

pub fn copy_iregs_from(&mut self, iregs: &IntRegisters)

pub fn clone_to(&self, other: &mut Vcpu)

Clone the entire VCPU state to another VCPU

This copies all registers including general-purpose registers, FPU context, Vector context, and PC.

pub fn store(&mut self, trapframe: &Trapframe)

pub fn switch(&mut self, trapframe: &mut Trapframe)

pub fn get_tls_pointer(&self) -> usize

Get the TLS (Thread Local Storage) pointer for this task

On RISC-V, TLS is stored in the tp register (x4).

pub fn set_tls_pointer(&mut self, ptr: usize)

Set the TLS (Thread Local Storage) pointer for this task

On RISC-V, TLS is stored in the tp register (x4).

Trait Implementations

impl Clone for Vcpu

fn clone(&self) -> Vcpu

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vcpu

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
