Package cpuid provides generic types used to represent CPU features supported by the architecture.

Types ¶

type CPU ¶

type CPU uint64

CPU is a bitset of feature flags representing the capabilities of various CPU architeectures that this package provides optimized assembly routines for.

The intent is to provide a stable ABI between the Go code that generate the assembly, and the program that uses the library functions.

func (CPU) Has ¶

func (cpu CPU) Has(feature Feature) bool

func (*CPU) Set ¶

func (cpu *CPU) Set(feature Feature, enabled bool)

type Feature ¶

type Feature uint64

Feature represents a single CPU feature.

const (
	// None is a Feature value that has no CPU features enabled.
	None Feature = 0
	// All is a Feature value that has all CPU features enabled.
	All Feature = 0xFFFFFFFFFFFFFFFF
)
