Device major numbers and device names for NVIDIA devices

Types

type Devices

type Devices interface {
	Exists(Name) bool
	Get(Name) (Major, bool)
}

Devices represents the set of devices under /proc/devices

func GetNVIDIADevices

func GetNVIDIADevices() (Devices, error)

GetNVIDIADevices returns the set of NVIDIA Devices on the machine

type DevicesMock

type DevicesMock struct {
	// ExistsFunc mocks the Exists method.
	ExistsFunc func(name Name) bool

	// GetFunc mocks the Get method.
	GetFunc func(name Name) (Major, bool)
	// contains filtered or unexported fields
}

DevicesMock is a mock implementation of Devices.

func TestSomethingThatUsesDevices(t *testing.T) {

	// make and configure a mocked Devices
	mockedDevices := &DevicesMock{
		ExistsFunc: func(name Name) bool {
			panic("mock out the Exists method")
		},
		GetFunc: func(name Name) (Major, bool) {
			panic("mock out the Get method")
		},
	}

	// use mockedDevices in code that requires Devices
	// and then make assertions.

}

func (*DevicesMock) Exists

func (mock *DevicesMock) Exists(name Name) bool

Exists calls ExistsFunc.

func (*DevicesMock) ExistsCalls

func (mock *DevicesMock) ExistsCalls() []struct {
	Name Name
}

ExistsCalls gets all the calls that were made to Exists. Check the length with:

len(mockedDevices.ExistsCalls())

func (*DevicesMock) Get

func (mock *DevicesMock) Get(name Name) (Major, bool)

Get calls GetFunc.

func (*DevicesMock) GetCalls

func (mock *DevicesMock) GetCalls() []struct {
	Name Name
}

GetCalls gets all the calls that were made to Get. Check the length with:

len(mockedDevices.GetCalls())

type Major

type Major int

Major represents a device major as specified under /proc/devices

type Name

type Name string

Name represents the name of a device as specified under /proc/devices
