Variables ¶

var KernelVersion = sync.OnceValues(detectKernelVersion)

KernelVersion returns the version of the currently running kernel.

Functions ¶

func FSType ¶

func FSType(path string) (int64, error)

func FindKConfig ¶

func FindKConfig() (*os.File, error)

FindKConfig searches for a kconfig file on the host.

It first reads from /boot/config- of the current running kernel and tries /proc/config.gz if nothing was found in /boot. If none of the file provide a kconfig, it returns an error.

func KernelRelease ¶

func KernelRelease() (string, error)

KernelRelease returns the release string of the running kernel. Its format depends on the Linux distribution and corresponds to directory names in /lib/modules by convention. Some examples are 5.15.17-1-lts and 4.19.0-16-amd64.

func ParseCPUsFromFile ¶

func ParseCPUsFromFile(path string) (int, error)

func PlatformPrefix ¶

func PlatformPrefix() string

PlatformPrefix returns the platform-dependent syscall wrapper prefix used by the linux kernel.
