Functions

func AMDGPU

func AMDGPU(cardName string) bool

AMDGPU check if a particular card is an AMD GPU by checking the device's vendor ID

func DevFunctional

func DevFunctional(cardName string) bool

DevFunctional does a simple check on whether a particular GPU is working by attempting to open the device

func FamilyIDtoString

func FamilyIDtoString(familyId uint32) (string, error)

FamilyID to String convert AMDGPU_FAMILY_* into string AMDGPU_FAMILY_* as defined in https://github.com/torvalds/linux/blob/master/include/uapi/drm/amdgpu_drm.h#L986

func GetAMDGPUs

func GetAMDGPUs() map[string]map[string]int

GetAMDGPUs return a map of AMD GPU on a node identified by the part of the pci address

func GetCardFamilyName

func GetCardFamilyName(cardName string) (string, error)

func GetFirmwareVersions

func GetFirmwareVersions(cardName string) (map[string]uint32, map[string]uint32, error)

GetFirmwareVersions obtain a subset of firmware and feature version via libdrm amdgpu_query_firmware_version

func ParseTopologyProperties

func ParseTopologyProperties(path string, re *regexp.Regexp) (int64, error)

ParseTopologyProperties parse for a property value in kfd topology file The format is usually one entry per line <name> <value>. Examples in testdata/topology-parsing/.
