Functions

func RestoreIrqBalanceConfig

func RestoreIrqBalanceConfig(irqBalanceConfigFile, irqBannedCPUConfigFile, irqSmpAffinityProcFile string) error

RestoreIrqBalanceConfig restores irqbalance service with original banned cpu mask settings

func UpdateIRQSmpAffinityMask

func UpdateIRQSmpAffinityMask(cpus, current string, set bool) (cpuMask, bannedCPUMask string, err error)

UpdateIRQSmpAffinityMask take input cpus that need to change irq affinity mask and the current mask string, return an update mask string and inverted mask, with those cpus enabled or disable in the mask.

Types

type HighPerformanceHooks

type HighPerformanceHooks struct {
	// contains filtered or unexported fields
}

HighPerformanceHooks used to run additional hooks that will configure a system for the latency sensitive workloads

func (*HighPerformanceHooks) PreStart

func (h *HighPerformanceHooks) PreStart(ctx context.Context, c *oci.Container, s *sandbox.Sandbox) error

func (*HighPerformanceHooks) PreStop

func (h *HighPerformanceHooks) PreStop(ctx context.Context, c *oci.Container, s *sandbox.Sandbox) error

type RuntimeHandlerHooks

type RuntimeHandlerHooks interface {
	PreStart(ctx context.Context, c *oci.Container, s *sandbox.Sandbox) error
	PreStop(ctx context.Context, c *oci.Container, s *sandbox.Sandbox) error
}

func GetRuntimeHandlerHooks

func GetRuntimeHandlerHooks(ctx context.Context, config *libconfig.Config, handler string, annotations map[string]string) (RuntimeHandlerHooks, error)

GetRuntimeHandlerHooks returns RuntimeHandlerHooks implementation by the runtime handler name
