Trait PowerIf 

pub trait PowerIf {
    // Required methods
    fn cpu_boot(cpu_id: usize, stack_top_paddr: usize);
    fn system_off() -> !;
    fn cpu_num() -> usize;
}

Power management interface.

Required Methods

fn cpu_boot(cpu_id: usize, stack_top_paddr: usize)

Available on crate feature smp only.

Bootstraps the given CPU core with the given initial stack (in physical address).

Where cpu_id is the logical CPU ID (0, 1, …, N-1, N is the number of CPU cores on the platform).

fn system_off() -> !

Shutdown the whole system.

fn cpu_num() -> usize

Get the number of CPU cores available on this platform.

The platform should either get this value statically from its configuration or dynamically by platform-specific methods.

For statically configured platforms, by convention, this value should be the same as MAX_CPU_NUM defined in the platform configuration.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
