The following constants define the nature of a link between two devices. These include peer-2-peer and NVLink information.

func GetNVLink

func GetNVLink(dev1 device.Device, dev2 device.Device) (P2PLinkType, error)

GetNVLink gets the number of NVLinks between the specified devices.

func GetP2PLink

func GetP2PLink(dev1 device.Device, dev2 device.Device) (P2PLinkType, error)

GetP2PLink gets the peer-to-peer connectivity between two devices.

func (P2PLinkType) String

func (l P2PLinkType) String() string

String returns the string representation of the P2PLink type.

type PciInfo

type PciInfo nvml.PciInfo

PciInfo is a type alias to nvml.PciInfo to allow for functions to be defined on the type.

func (PciInfo) BusID

func (p PciInfo) BusID() string

BusID provides a utility function that returns the string representation of the bus ID. Note that the []int8 slice member is named BusId.

func (PciInfo) CPUAffinity

func (p PciInfo) CPUAffinity() *uint

CPUAffinity returns the CPU affinity associated with a specified PCI device. If NUMA information is not available, this returns nil.

func (PciInfo) NumaNode

func (p PciInfo) NumaNode() int64

NumaNode returns the numa node associates with a PCI device. If numa is unsupported, -1 is returned.
