Struct CPUInfo

Source

pub struct CPUInfo;

Expand description

CPU information structure. Provides frequency and TSC-to-cycle scaling information.

Implementations§

Source §

impl CPUInfo

Source

pub fn get_frequency_hz() -> FreqInfo

Get current core frequency. Runs known latency loop and time it. This information allows to calculate core frequency. Current method might not work correctly when something running on second thread (SMT).

Source

pub fn get_frequency_ghz() -> FreqInfo

Get core frequency in GHz. Uses CPUInfo::get_frequency_hz method.

Source

pub fn get_time_stamp() -> u64

Get current CPU time stamp counter value Uses RDTSC instruction on x86 architectures
