Types ¶

type EFIFFSFileHeader ¶

type EFIFFSFileHeader struct {
	Name           [16]uint8
	HeaderChecksum uint8
	FileChecksum   uint8
	Type           uint8
	Attributes     uint8
	Size           [3]uint8
	State          uint8
}

func (*EFIFFSFileHeader) UnmarshalBinary ¶

func (e *EFIFFSFileHeader) UnmarshalBinary(data []byte) error

UnmarshalBinary unmarshals the EFIFFSFileHeader from binary data.

type EFIFirmwareVolumeHeader ¶

type EFIFirmwareVolumeHeader struct {
	ZeroVector      [16]uint8
	FileSystemGUID  [16]uint8
	FvLength        uint64
	Signature       [4]uint8
	Attributes      uint32
	HeaderLength    uint16
	Checksum        uint16
	ExtHeaderOffset uint16
	Reserved        uint8
	Revision        uint8
}

func (*EFIFirmwareVolumeHeader) UnmarshalBinary ¶

func (e *EFIFirmwareVolumeHeader) UnmarshalBinary(data []byte) error

UnmarshalBinary unmarshals the FiwmreareVolumeHeader from binary data.

type FVImage ¶

type FVImage struct {
	ImageBase    uintptr
	SerialConfig SerialPortConfig
	// contains filtered or unexported fields
}

FVImage is a structure for loading a firmware volume

func New ¶

func New(n string) (*FVImage, error)

New loads the file and return FVImage stucture if entry image is found

func (*FVImage) Load ¶

func (fv *FVImage) Load(verbose bool) error

Load loads fimware volume payload and boot the the payload

type SerialPortConfig ¶

type SerialPortConfig struct {
	Type        uint32
	BaseAddr    uint32
	Baud        uint32
	RegWidth    uint32
	InputHertz  uint32
	UartPciAddr uint32
}

SerialPortConfig defines debug port configuration This struct will be used to initialize SERIAL_PORT_INFO in payload (UefiPayloadPkg/Include/Guid/SerialPortInfoGuid.h)
