CpuId

Struct CpuId 

Source
pub struct CpuId { /* private fields */ }
Expand description

CPU identifier

Represents a logical CPU in the system. On x86_64, this corresponds to the APIC ID.

Implementations§

Source§

impl CpuId

Source

pub const fn new(id: usize) -> Self

Creates a new CpuId from a raw ID

Source

pub const fn id(&self) -> usize

Returns the raw CPU ID value

Source

pub const fn bsp() -> Self

Returns the CpuId of the bootstrap processor (BSP)

Source

pub fn current_racy() -> Self

Returns the CpuId of the currently executing CPU

§Safety

This function reads the per-CPU GS base to determine the current CPU. It requires that per-CPU data has been initialized for this CPU.

Source

pub fn num_cpus() -> usize

Returns the number of CPUs in the system

Source

pub fn iter() -> CpuIter

Returns an iterator over all CPUs
