m1cpu: fetch l1, l2 cache data for p/e cores
The go-m1cpu module is a library for inspecting Apple Silicon CPUs in Go.
Use the m1cpu library for looking up the CPU frequency for Apple M1 and M2 CPUs.
go get github.com/shoenig/go-m1cpu@latest
package main
import (
"fmt"
"github.com/shoenig/go-m1cpu"
)
func main() {
fmt.Println("Apple Silicon", m1cpu.IsAppleSilicon())
fmt.Println("pCore GHz", m1cpu.PCoreGHz())
fmt.Println("eCore GHz", m1cpu.ECoreGHz())
fmt.Println("pCore Hz", m1cpu.PCoreHz())
fmt.Println("eCore Hz", m1cpu.ECoreHz())
}
This package requires the use of CGO. Extracting the CPU properties is done via Apple's IOKit framework, which is accessible only through system C libraries.
