Functions

func LaidOutVolumesFromGadget 

func LaidOutVolumesFromGadget(gadgetRoot, kernelRoot string, model gadget.Model, encType secboot.EncryptionType, volToGadgetToDiskStruct map[string]map[int]*gadget.OnDiskStructure) (all map[string]*gadget.LaidOutVolume, err error)

func LayoutFromYaml 

func LayoutFromYaml(newDir, gadgetYaml string, model gadget.Model) (*gadget.LaidOutVolume, error)

LayoutFromYaml returns a LaidOutVolume for the given gadget.yaml string. It currently only supports gadget.yaml's with a single volume in them. An empty directory to use to create a gadget.yaml file should be provided, such as c.MkDir() in tests.

func LayoutMultiVolumeFromYaml 

func LayoutMultiVolumeFromYaml(newDir, kernelDir, gadgetYaml string, model gadget.Model) (map[string]*gadget.LaidOutVolume, error)

LayoutMultiVolumeFromYaml returns all LaidOutVolumes for the given gadget.yaml string and works for either single or multiple volume gadget.yaml's. An empty directory to use to create a gadget.yaml file should be provided, such as c.MkDir() in tests.

func MakeMockGadget 

func MakeMockGadget(gadgetRoot, gadgetContent string) error

func MockGadgetPartitionedDisk 

func MockGadgetPartitionedDisk(gadgetYaml, gadgetRoot string) (ginfo *gadget.Info, laidVols map[string]*gadget.LaidOutVolume, model *asserts.Model, restore func(), err error)

func MustLayOutSingleVolumeFromGadget 

func MustLayOutSingleVolumeFromGadget(gadgetRoot, kernelRoot string, model gadget.Model) (*gadget.LaidOutVolume, error)

MustLayOutSingleVolumeFromGadget takes a gadget rootdir and lays out the partitions as specified. This function does not handle multiple volumes and is meant for test helpers only. For runtime users, with multiple volumes handled by choosing the ubuntu-* role volume, see LaidOutVolumesFromGadget

func VolumeFromYaml 

func VolumeFromYaml(newDir, gadgetYaml string, model gadget.Model) (*gadget.Volume, error)

func WriteGadgetYaml 

func WriteGadgetYaml(newDir, gadgetYaml string) (string, error)

func WriteGadgetYamlReadInfo 

func WriteGadgetYamlReadInfo(newDir, gadgetYaml string, model gadget.Model) (*gadget.Info, string, error)

Types

type ModelCharacteristics 

type ModelCharacteristics struct {
	IsClassic bool
	HasModes  bool
}

func (*ModelCharacteristics) Classic 

func (m *ModelCharacteristics) Classic() bool

func (*ModelCharacteristics) Grade 

func (m *ModelCharacteristics) Grade() asserts.ModelGrade
