Functions

func BootstrapWorkloadPinningMC

func BootstrapWorkloadPinningMC(role string, pinningMode *apiconfigv1.CPUPartitioningMode) (*machineconfigv1.MachineConfig, error)

BootstrapWorkloadPinningMC creates an initial state MachineConfig resource that establishes an empty CPU set for both CRIO config and Kubelet config. The purpose is provide empty state initialization for both CRIO and Kubelet so that the nodes always start and join the cluster in a Workload Pinning configuration.

When a performance profiles is created, they will override the config files in this MC with the desired CPU Set. If that performance profile were to be deleted later on, this initial MC will be the fallback that MCO re-renders and maintain a workload pinning configuration.

func GetHugepagesSizeKilobytes

func GetHugepagesSizeKilobytes(hugepagesSize performancev2.HugePageSize) (string, error)

GetHugepagesSizeKilobytes retruns hugepages size in kilobytes

func GetMachineConfigName

func GetMachineConfigName(profileName string) string

GetMachineConfigName generates machine config name from the performance profile

func MoveOvsIntoOwnSlice

func MoveOvsIntoOwnSlice() (bool, string)

func New

func New(profile *performancev2.PerformanceProfile, opts *components.MachineConfigOptions) (*machineconfigv1.MachineConfig, error)

New returns new machine configuration object for performance sensitive workloads
