Functions ¶

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 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 WriteGadgetYaml ¶

func WriteGadgetYaml(newDir, gadgetYaml string) (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
