Functions

func GetEditsForComputeInstance

func GetEditsForComputeInstance(logger logger.Interface, driverRoot string, gpu int, gi int, ci int) (*cdi.ContainerEdits, error)

GetEditsForComputeInstance returns the CDI edits for a particular compute instance defined by the (gpu, gi, ci) tuple

func NewDriverBinariesDiscoverer

func NewDriverBinariesDiscoverer(logger logger.Interface, driverRoot string) discover.Discover

NewDriverBinariesDiscoverer creates a discoverer for GSP firmware associated with the GPU driver.

func NewDriverDiscoverer

func NewDriverDiscoverer(logger logger.Interface, driver *root.Driver, nvidiaCTKPath string, nvmllib nvml.Interface) (discover.Discover, error)

NewDriverDiscoverer creates a discoverer for the libraries and binaries associated with a driver installation. The supplied NVML Library is used to query the expected driver version.

func NewDriverFirmwareDiscoverer

func NewDriverFirmwareDiscoverer(logger logger.Interface, driverRoot string, version string) (discover.Discover, error)

NewDriverFirmwareDiscoverer creates a discoverer for GSP firmware associated with the specified driver version.
