Seth Hoenig	8617ff654a	cpu: add frequency support for apple silicon m1/m2 cpus This PR adds support for reading the frequency of Apple Silicon M1/M2 CPUs. We do so by reading the values out of the IOKit framework, as a few other projects have now demonstrated to be possible. This requires the use of CGO. The library provides a convenience IsAppleSilicon() guard to detect whether the values can be read. Currently gopsutil does not support the big.LITTLE CPU architectures (i think?) - in fact the P and E cores have different max frequencies. For now, just read the P core frequency. The E core data is readily available if we want to read it in the future. Closes #1000 Small example program ```go package main import ( "fmt" "github.com/shoenig/go-m1cpu" "github.com/shirou/gopsutil/v3/cpu" ) func main() { fmt.Println("is Apple Silicon:", m1cpu.IsAppleSilicon()) fmt.Println("model name", m1cpu.ModelName()) fmt.Println("pCore GHz", m1cpu.PCoreGHz()) fmt.Println("eCore GHz", m1cpu.ECoreGHz()) fmt.Println("pCore Hz", m1cpu.PCoreHz()) fmt.Println("eCore Hz", m1cpu.ECoreHz()) fmt.Println("----- gopsutil ----") infos, err := cpu.Info() if err != nil { panic(err) } for _, info := range infos { fmt.Println("info.Mhz", info.Mhz) } } ``` ```shell go run main.go is Apple Silicon: true model name Apple M2 Pro pCore GHz 3.504 eCore GHz 2.424 pCore Hz 3504000000 eCore Hz 2424000000 ----- gopsutil ---- info.Mhz 3.504e+09 ```	2 years ago

Tobias Klauser	ee12f66e4d	cpu, v3/cpu: use sysconf package instead of exec'ing getconf Currently, ClocksPerSec is determined by exec'ing getconf in func init, i.e. on startup of every program importing the package. getconf might not be present on some systems or is not executable by the current user. To avoid this hard to control dependency, use the github.com/tklauser/go-sysconf package which implements sysconf(3) entirely in Go without cgo. The package is supported on all platforms currently supported by the cpu and v3/cpu package of gopsutil.	4 years ago

K.C. Wong	123a6c9b0d	Addressing frequency unit discrepancies * for Darwin, it is a minor tweak for readability: the value returned is in Hz, so using a variable named 'hz' makes more sense than 'mhz' * for Linux, the unit is in kHz so we need to divide the value from `cpuinfo_max_freq` by 10^3 to get MHz (see cpu-freq/user-guide.txt of the kernel documentation)	9 years ago
