Functions

func IsModuleLoaded

func IsModuleLoaded(searchedModule string) bool

IsModuleLoaded tells whether given kernel module is loaded or not.

func LoadModule

func LoadModule(module string) error

LoadModule loads a kernel module (via modprobe).

func UnloadModule

func UnloadModule(module string) error

UnloadModule unloads a kernel module (via rmmod).

Types

type DeviceStruct

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

type PCILister

type PCILister struct{}

PCILister is the object responsible for discovering initial pool of devices and their allocation.

func (PCILister) Discover

func (pci PCILister) Discover(pluginListCh chan dpm.PluginNameList)

Discover discovers all PCI devices within the system.

func (PCILister) GetResourceNamespace

func (pci PCILister) GetResourceNamespace() string

func (PCILister) NewPlugin

func (pci PCILister) NewPlugin(vendorID string) dpm.PluginInterface

NewPlugin creates a device plugin for specific deviceID, using deviceIDs as initial device "pool".

type VFIODevicePlugin

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

VFIODevicePlugin represents device plugin implementation with VFIO specific attributes.

func (*VFIODevicePlugin) Allocate

func (dpi *VFIODevicePlugin) Allocate(ctx context.Context, r *pluginapi.AllocateRequest) (*pluginapi.AllocateResponse, error)

Allocate allocates a set of devices to be used by container runtime environment.

func (VFIODevicePlugin) GetDevicePluginOptions

func (VFIODevicePlugin) GetDevicePluginOptions(context.Context, *pluginapi.Empty) (*pluginapi.DevicePluginOptions, error)

GetDevicePluginOptions returns options to be communicated with Device Manager

func (*VFIODevicePlugin) ListAndWatch

func (dpi *VFIODevicePlugin) ListAndWatch(e *pluginapi.Empty, s pluginapi.DevicePlugin_ListAndWatchServer) error

ListAndWatch lists devices.

func (VFIODevicePlugin) PreStartContainer

func (VFIODevicePlugin) PreStartContainer(context.Context, *pluginapi.PreStartContainerRequest) (*pluginapi.PreStartContainerResponse, error)

PreStartContainer is called, if indicated by Device Plugin during registeration phase, before each container start. Device plugin can run device specific operations such as reseting the device before making devices available to the container
