Functions

func AddDefaultResourcesToConfig

func AddDefaultResourcesToConfig(config *util.DeviceConfig) error

AddDefaultResourcesToConfig adds default resource matching rules to config.Resources

Types

type AnnotatedID

type AnnotatedID string

AnnotatedID represents an ID with a replica number embedded in it.

func NewAnnotatedID

func NewAnnotatedID(id string, replica int) AnnotatedID

NewAnnotatedID creates a new AnnotatedID from an ID and a replica number.

func (AnnotatedID) GetID

func (r AnnotatedID) GetID() string

GetID returns just the ID part of the replicated ID

func (AnnotatedID) HasAnnotations

func (r AnnotatedID) HasAnnotations() bool

HasAnnotations checks if an AnnotatedID has any annotations or not.

func (AnnotatedID) Split

func (r AnnotatedID) Split() (string, int)

Split splits a AnnotatedID into its ID and replica number parts.

type AnnotatedIDs

type AnnotatedIDs []string

AnnotatedIDs can be used to treat a []string as a []AnnotatedID.

func (AnnotatedIDs) AnyHasAnnotations

func (rs AnnotatedIDs) AnyHasAnnotations() bool

AnyHasAnnotations checks if any ID has annotations or not.

func (AnnotatedIDs) GetIDs

func (rs AnnotatedIDs) GetIDs() []string

GetIDs returns just the ID parts of the annotated IDs as a []string

type Device

type Device struct {
	kubeletdevicepluginv1beta1.Device
	Paths []string
	Index string
}

Device wraps kubeletdevicepluginv1beta1.Device with extra metadata and functions.

func BuildDevice

func BuildDevice(index string, d deviceInfo) (*Device, error)

BuildDevice builds an rm.Device with the specified index and deviceInfo

func (Device) AlignedAllocationSupported

func (d Device) AlignedAllocationSupported() bool

AlignedAllocationSupported checks whether the device supports an alligned allocation

func (Device) GetUUID

func (d Device) GetUUID() string

GetUUID returns the UUID for the device from the annotated ID.

func (Device) IsMigDevice

func (d Device) IsMigDevice() bool

IsMigDevice returns checks whether d is a MIG device or not.

type DeviceMap

type DeviceMap map[spec.ResourceName]Devices

DeviceMap stores a set of devices per resource name.

func NewDeviceMap

func NewDeviceMap(nvmllib nvml.Interface, config *util.DeviceConfig) (DeviceMap, error)

NewDeviceMap creates a device map for the specified NVML library and config.

type Devices

type Devices map[string]*Device

Devices wraps a map[string]*Device with some functions.

func (Devices) AlignedAllocationSupported

func (ds Devices) AlignedAllocationSupported() bool

AlignedAllocationSupported checks whether all devices support an alligned allocation

func (Devices) Contains

func (ds Devices) Contains(ids ...string) bool

Contains checks if Devices contains devices matching all ids.

func (Devices) Difference

func (ds Devices) Difference(ods Devices) Devices

Difference returns the set of devices contained in ds but not in ods.

func (Devices) GetByID

func (ds Devices) GetByID(id string) *Device

GetByID returns a reference to the device matching the specified ID (nil otherwise).

func (Devices) GetByIndex

func (ds Devices) GetByIndex(index string) *Device

GetByIndex returns a reference to the device matching the specified Index (nil otherwise).

func (Devices) GetIDs

func (ds Devices) GetIDs() []string

GetIDs returns the ids from all devices in the Devices

func (Devices) GetIndices

func (ds Devices) GetIndices() []string

GetIndices returns the Indices from all devices in the Devices

func (Devices) GetPaths

func (ds Devices) GetPaths() []string

GetPaths returns the Paths from all devices in the Devices

func (Devices) GetPluginDevices

func (ds Devices) GetPluginDevices() []*kubeletdevicepluginv1beta1.Device

GetPluginDevices returns the plugin Devices from all devices in the Devices

func (Devices) Subset

func (ds Devices) Subset(ids []string) Devices

Subset returns the subset of devices in Devices matching the provided ids. If any id in ids is not in Devices, then the subset that did match will be returned.

type ResourceManager

type ResourceManager interface {
	Resource() spec.ResourceName
	Devices() Devices
	GetDevicePaths([]string) []string
	GetPreferredAllocation(available, required []string, size int) ([]string, error)
	CheckHealth(stop <-chan interface{}, unhealthy chan<- *Device) error
}

ResourceManager provides an interface for listing a set of Devices and checking health on them

func NewNVMLResourceManagers

func NewNVMLResourceManagers(nvmllib nvml.Interface, config *util.DeviceConfig) ([]ResourceManager, error)

NewNVMLResourceManagers returns a set of ResourceManagers, one for each NVML resource in 'config'.

func NewResourceManagers

func NewResourceManagers(nvmllib nvml.Interface, config *util.DeviceConfig) ([]ResourceManager, error)

NewResourceManagers returns a []ResourceManager, one for each resource in 'config'.
