Functions

func GetCPU

func GetCPU() uint32

GetCPU returns the caller's current CPU number, without using the Linux VDSO (which is not available to the sentry) or the getcpu(2) system call (which is relatively slow).

func MaxPossibleCPU

func MaxPossibleCPU() (uint32, error)

MaxPossibleCPU returns the highest possible CPU number, which is guaranteed not to change for the lifetime of the host kernel.
