CpuAreaPrefix

cpu_local

Struct CpuAreaPrefix 

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

Fixed three-cache-line prefix of every initialized runtime CPU area.

Implementations§

Source§

impl CpuAreaPrefix

Source

pub fn initialize( cpu_index: CpuIndex, area_base: usize, ) -> Result<Self, CpuLocalError>

Constructs the prefix value for one exclusively owned offline area.

§Errors

Returns an address error when area_base is null, misaligned, or its fixed boot-context address overflows.

Source

pub const fn header(&self) -> &CpuAreaHeader

Returns immutable area identity.

Source

pub const fn runtime_anchor(&self) -> &CpuRuntimeAnchor

Returns CPU runtime and trap state.

Source

pub const fn boot_context(&self) -> &BootContextHeader

Returns the permanent boot execution-context header.
