Trait VmArchPerCpuOps 

pub trait VmArchPerCpuOps: Sized {
    // Required methods
    fn new(cpu_id: usize) -> VmBackendResult<Self>;
    fn is_enabled(&self) -> bool;
    fn hardware_enable(&mut self) -> VmBackendResult;
    fn hardware_disable(&mut self) -> VmBackendResult;

    // Provided methods
    fn max_guest_page_table_levels(&self) -> usize { ... }
    fn guest_phys_addr_bits(&self) -> usize { ... }
    fn timer_frequency_hz(&self) -> Option<u64> { ... }
}

Architecture-specific per-CPU virtualization state consumed by AxVM.

Required Methods

fn new(cpu_id: usize) -> VmBackendResult<Self>

Creates a new per-CPU state.

fn is_enabled(&self) -> bool

Whether virtualization is enabled on the current CPU.

fn hardware_enable(&mut self) -> VmBackendResult

Enables virtualization on the current CPU.

fn hardware_disable(&mut self) -> VmBackendResult

Disables virtualization on the current CPU.

Provided Methods

fn max_guest_page_table_levels(&self) -> usize

Returns the max guest page table levels supported by this architecture.

fn guest_phys_addr_bits(&self) -> usize

Returns the guest physical address width supported by this CPU.

fn timer_frequency_hz(&self) -> Option<u64>

Returns the architectural counter frequency recorded on this CPU.

Architectures without an ARM-style shared counter return None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
