Expand description

Per-CPU descriptor tables: one TSS and GDT per CPU, plus the shared IDT.

Implementations§

Source§

impl Cpu

Source

pub const fn new() -> Self

Construct with a default TSS and GDT for every CPU and a fresh IDT.

Source

pub unsafe fn init_ap_cpu_states(&self, value: Box<[CpuState]>)

Source

pub fn global_cpu_state(&self) -> &GlobalCpuState

Getter for Cpu::global_cpu_state

Source

pub fn bsp_cpu_state(&self) -> &CpuState

Getter for Cpu::bsp_cpu_state

Source

pub unsafe fn ap_cpu_states(&self) -> &Option<Box<[CpuState]>>

Getter for Cpu::ap_cpu_states

§Safety

The caller must guarantee that at this method’s entire execution time, no mutable references or pointers to this data exist or will exist
