Module interface_args 

Data structures for describing the parameters of the various FF-A interfaces.

Structs

DirectMsg2Args

Arguments for the FFA_MSG_SEND_DIRECT_{REQ,RESP}2 interfaces.

LogChars

Generic type for storing FFA_CONSOLE_LOG character payload and its length in bytes.

MsgSend2Flags

Flags field of the FFA_MSG_SEND2 interface.

MsgWaitFlags

Flags field of the FFA_MSG_WAIT interface.

SuccessArgsFeatures

FFA_FEATURES specific success argument structure. This type needs further specialization based on ‘FF-A function ID or Feature ID’ field of the preceeding FFA_FEATURES request.

SuccessArgsIdGet

FFA_ID_GET specific success argument structure.

SuccessArgsSpmIdGet

FFA_SPM_ID_GET specific success argument structure.

TargetInfo

Endpoint ID and vCPU ID pair, used by FFA_ERROR, FFA_INTERRUPT and FFA_RUN interfaces.

VersionFlags

Flags for the FFA_VERSION interface.

Enums

ConsoleLogChars

Argument for the FFA_CONSOLE_LOG interface.

DirectMsgArgs

Arguments for the FFA_MSG_SEND_DIRECT_{REQ,RESP} interfaces.

Feature

Arguments for the FFA_FEATURES interface.

FeatureId

Feature IDs used by the FFA_FEATURES interface.

MemAddr

Memory address argument for FFA_MEM_PERM_{GET,SET} interfaces.

MemOpBuf

Descriptor for a dynamically allocated memory buffer that contains the memory transaction descriptor.

RxTxAddr

RXTX buffer descriptor, used by FFA_RXTX_MAP.

SecondaryEpRegisterAddr

Entrypoint address argument for FFA_SECONDARY_EP_REGISTER interface.

SuccessArgs

Generic arguments of the FFA_SUCCESS interface. The interpretation of the arguments depends on the interface that initiated the request. The application code has knowledge of the request, so it has to convert SuccessArgs into/from a specific success args structure that matches the request.

VersionQueryType

Version query types for the FFA_VERSION interface.

VmAvailabilityStatus

Composite type for capturing success and error return codes for the VM availability messages.

WarmBootType

Arguments for the Power Warm Boot FFA_MSG_SEND_DIRECT_REQ interface.

Type Aliases

ConsoleLogChars32

Specialized type for 32-bit FFA_CONSOLE_LOG payload.

ConsoleLogChars64

Specialized type for 64-bit FFA_CONSOLE_LOG payload.
