Struct ArmPerCpu 

pub struct ArmPerCpu {
    pub cpu_id: usize,
    pub original_vbar_el2: u64,
    /* private fields */
}

Per-CPU AArch64 virtualization state.

Fields

cpu_id: usize

per cpu id

original_vbar_el2: u64

The original value of VBAR_EL2 (exception vector base) before enabling the virtualization.

Implementations

impl ArmPerCpu

pub fn new(cpu_id: usize) -> ArmVcpuResult<Self>

Creates per-CPU virtualization state.

pub fn is_enabled(&self) -> bool

Returns whether AArch64 virtualization is enabled on the current CPU.

pub fn hardware_enable<H: ArmHostOps>(&mut self) -> ArmVcpuResult

Enables AArch64 virtualization on the current CPU.

pub fn hardware_disable(&mut self) -> ArmVcpuResult

Disables AArch64 virtualization on the current CPU.

pub fn max_guest_page_table_levels(&self) -> usize

Returns the maximum guest page table levels supported by this CPU.

pub fn guest_phys_addr_bits(&self) -> usize

Returns the guest physical address width supported by this CPU.

pub const fn timer_frequency_hz(&self) -> u64

Returns the architectural counter frequency recorded on this CPU.
