Implementations§

§

impl ExtendedTopologyLevel

pub fn processors(&self) -> u16

Number of logical processors at this level type. The number reflects configuration as shipped.

pub fn level_number(&self) -> u8

Level number.

pub fn level_type(&self) -> TopologyType

pub fn x2apic_id(&self) -> u32

x2APIC ID the current logical processor. (Bits 31-00)

pub fn shift_right_for_next_apic_id(&self) -> u32

Number of bits to shift right on x2APIC ID to get a unique topology ID of the next level type. (Bits 04-00) All logical processors with the same next level ID share current level.
