Functions

func AlignOOMPriority

func AlignOOMPriority(qosLevel string, userSpecifiedScore *int) (oomPriorityScore int)

func AnnotationsIndicateNUMABinding

func AnnotationsIndicateNUMABinding(annotations map[string]string) bool

func AnnotationsIndicateNUMAExclusive

func AnnotationsIndicateNUMAExclusive(annotations map[string]string) bool

func GetOOMPriority

func GetOOMPriority(qosConf *generic.QoSConfiguration, pod *v1.Pod) (priority *int, invalid bool)

GetOOMPriority parse the user specified oom priority from memory enhancement annotation

func GetPodCPUSuppressionToleranceRate

func GetPodCPUSuppressionToleranceRate(qosConf *generic.QoSConfiguration, pod *v1.Pod) (float64, error)

GetPodCPUSuppressionToleranceRate parses cpu suppression tolerance rate for the given pod, and cpu suppression is only supported for reclaim pods. if the given is not nominated with cpu suppression, return max to indicate that it can be suppressed for any degree.

func GetPodNetClassID

func GetPodNetClassID(podAnnotations map[string]string, podLevelNetClassAnnoKey string) (bool, uint32, error)

GetPodNetClassID parses net class id for the given pod. if the given pod doesn't specify a class id, the first value returned will be false

func GetRSSOverUseEvictThreshold

func GetRSSOverUseEvictThreshold(qosConf *generic.QoSConfiguration, pod *v1.Pod) (threshold *float64, invalid bool)

GetRSSOverUseEvictThreshold parse the user specified threshold and checks if it's valid

func IsPodNumaBinding

func IsPodNumaBinding(qosConf *generic.QoSConfiguration, pod *v1.Pod) bool

IsPodNumaBinding checks whether the pod needs numa-binding

func IsPodNumaExclusive

func IsPodNumaExclusive(qosConf *generic.QoSConfiguration, pod *v1.Pod) bool

IsPodNumaExclusive checks whether the pod needs numa-exclusive

func ParseMemoryEnhancement

func ParseMemoryEnhancement(qosConf *generic.QoSConfiguration, pod *v1.Pod) map[string]string
