Functions

func AddKernel 

func AddKernel(ctx context.Context, log *logrus.Logger, dir string, cnf *KernelConf, flags AddKernelFlags) error

func BuildKernel 

func BuildKernel(ctx context.Context, log *logrus.Logger, dir, kname string, fetch bool, arch string) error

func CheckEnvironment 

func CheckEnvironment() error

NB(kkourt): for now, just a single check for everything

func FetchKernel 

func FetchKernel(ctx context.Context, log *logrus.Logger, dir, kname string) error

func FindKernel 

func FindKernel(installDir string) (string, error)

func GetConfigGroupNames 

func GetConfigGroupNames() []string

func GetExamplesText 

func GetExamplesText() string

func InitDir 

func InitDir(log *logrus.Logger, dir string, conf *Conf, flags InitDirFlags) error

Initalizes a new directory for kernels (it will create it if it does not exist).

the provided conf will be saved in the directory. if conf is nil, an empty configuration will be used.

func RemoveKernel 

func RemoveKernel(ctx context.Context, log_ *logrus.Logger, dir string, name string, backupConf bool) error

RemoveKernel will remove a kernel. It will typically try to continue, even if it encounters an error

Types

type AddKernelFlags 

type AddKernelFlags struct {
	BackupConf bool
	Fetch      bool

type ConfigOption 

type ConfigOption []string

ConfigOption are switches passed to scripts/config in a kernel dir

type GitURL 

type GitURL struct {
	Repo string

	// Branch in remote (by default, master)
	Branch string

	// depth for shallow directories (-1 means clone the full repo)
	ShallowDepth int
}

type InitDirFlags 

type InitDirFlags struct {
	Force      bool
	BackupConf bool
}

type KernelConf 

type KernelConf struct {
