Functions

func GetTokenIDString

func GetTokenIDString(tokenID TokenID) string

GetTokenIDString returns literal representation of known Token IDs otherwise an empty string

func UpsertToken

func UpsertToken(tokenID TokenID, priorityMask PriorityMask, boardMask uint16, newValue interface{}, apcbBinary []byte) error

UpsertToken inserts a new token or updates current into apcb binary

Types

type PriorityLevel

type PriorityLevel uint8

PriorityLevel describes APCB BInary token priority level (APCB_PRIORITY_LEVEL in AGESA source code)

const (
	PriorityLevelHardForce    PriorityLevel = 1
	PriorityLevelHigh         PriorityLevel = 2
	PriorityLevelMedium       PriorityLevel = 3
	PriorityLevelEventLogging PriorityLevel = 4
	PriorityLevelLow          PriorityLevel = 5
	PriorityLevelDefault      PriorityLevel = 6
)

Defines existing APCB token priority levels

func (PriorityLevel) String

func (pl PriorityLevel) String() string

type PriorityMask

type PriorityMask uint8

PriorityMask specifies a combined set of APCBPriorityLevels

func CreatePriorityMask

func CreatePriorityMask(levels ...PriorityLevel) PriorityMask

CreatePriorityMask combines PriorityLevel into a APCBPriorityMask

func (PriorityMask) String

func (m PriorityMask) String() string

type Token

type Token struct {
	ID           TokenID
	PriorityMask PriorityMask
	BoardMask    uint16
	Value        interface{} // One of the following bool, uint8, uint16, uint32
}

Token represents an APCB token

func ParseAPCBBinaryTokens

func ParseAPCBBinaryTokens(apcbBinary []byte) ([]Token, error)

ParseAPCBBinaryTokens returns all tokens contained in the APCB Binary

func (Token) NumValue

func (t Token) NumValue() uint32

NumValue returns Token's value as uint32

type TokenID

type TokenID uint32

TokenID is a unique token identifier

const (
	TokenIDPSPMeasureConfig   TokenID = 0xDD3AD029
	TokenIDPSPEnableDebugMode TokenID = 0xD1091CD0
	TokenIDPSPErrorDisplay    TokenID = 0xDC33FF21
	TokenIDPSPStopOnError     TokenID = 0xE7024A21
)
