Implementations§

source§

impl<R: CpuIdReader> HypervisorInfo<R>

source

pub fn identify(&self) -> Hypervisor

Returns the identity of the Hypervisor.

§Technical Background

The value is a 12-byte (12 character) fixed-length ASCII string.

Usually all of these IDs can be found in the original source code on Github relatively easy (if the project is open source). Once you have an ID, you find cumulated lists with all kinds of IDs on Github relatively easy.

source

pub fn tsc_frequency(&self) -> Option<u32>

TSC frequency in kHz.

source

pub fn apic_frequency(&self) -> Option<u32>

(Virtual) Bus (local apic timer) frequency in kHz.
