Overview

Package linux contains Linux-specific pieces of interrogation which are nonetheless testable on arbitrary platforms.

Functions

func GPUs

func GPUs(ctx context.Context, lspciOutput string, versionGetters VendorsToVersionGetters) ([]string, error)

GPUs returns a slice of Swarming-style descriptors of all the GPUs on the host, in all precisions: "vendorID", "vendorID-deviceID", and, if detectable, "vendorID-deviceID-driverVersion". nvidiaVersionGetter is a thunk that returns the version of the installed Nvidia driver. intelVersionGetter is similar but for the Intel driver.

func OSVersions

func OSVersions(platform, version string) []string

func VendorAndBrand

func VendorAndBrand(cpuInfo io.Reader) (vendor, brandString string, err error)

VendorAndBrand returns the vendor and brand string of the first encountered CPU in the provided contents of /proc/cpuinfo. Extraction may fail and they may be empty--those are valid values--even if error is nil.

Types

type VendorsToVersionGetters

type VendorsToVersionGetters = map[string]func(context.Context) string

VendorsToVersionGetters is a map of vendor IDs to functions that return GPU driver versions for those vendors' products.
