Functions

func FindOrphanedCPUs

func FindOrphanedCPUs(domains []PCIeDomain, allCPUs cpuset.CPUSet) cpuset.CPUSet

func IsPCIeRootName

func IsPCIeRootName(name string) bool

IsPCIeRootName matches the constructions of the pcie roots in the linux kernel. The kernel format string is "pci%04x:%02x" (linux 7.0.9: drivers/pci/probe.c:1028).

func MapCPUsToPCIeDomain

func MapCPUsToPCIeDomain(domains []PCIeDomain, allCPUs cpuset.CPUSet) map[int][]*PCIeDomain

MapCPUsToPCIeDomain returns a map cpuid -> pciedomains

func SetCompatibilityAttributes

func SetCompatibilityAttributes(attrs map[resourceapi.QualifiedName]resourceapi.DeviceAttribute, numaID int64)

SetCompatibilityAttributes add attributes to enable compatibility (e.g. alignment) with other DRA resource drivers leveraging attributes which are not kubernetes standard. This is the "staging area" which enables attribute sharing until (or before) they become standard.

Types

func (PCIeDomain) String

func (pcd PCIeDomain) String() string

type SysFS

type SysFS interface {
	fs.ReadLinkFS
