Detailed Description

Arm SiP services communication protocol between service provider and client.

Client to fill in the input data in struct sip_svc_request format when requesting SMC/HVC service via 'send' function.

Service to fill in the SMC/HVC return value in struct sip_svc_response format and pass to client via Callback.

Macro Definition Documentation

◆ SIP_SVC_ID_INVALID

#define SIP_SVC_ID_INVALID 0xFFFFFFFF

Invalid id value.

◆ SIP_SVC_PROTO_CMD_ASYNC

#define SIP_SVC_PROTO_CMD_ASYNC 0x1

◆ SIP_SVC_PROTO_CMD_MAX

#define SIP_SVC_PROTO_CMD_MAX SIP_SVC_PROTO_CMD_ASYNC

◆ SIP_SVC_PROTO_CMD_SYNC

#define SIP_SVC_PROTO_CMD_SYNC 0x0

Arm SiP services command code in request header.

SIP_SVC_PROTO_CMD_SYNC

Typical flow, synchronous request. Service expects EL3/EL2 firmware to return the result immediately during SMC/HVC call.

SIP_SVC_PROTO_CMD_ASYNC

Asynchronous request. Service is required to poll the response via a separate SMC/HVC call. Use this method if the request requires longer processing in EL3/EL2.

◆ SIP_SVC_PROTO_HEADER

#define SIP_SVC_PROTO_HEADER	(	code,
		trans_id
	)

Value:

        ((((code)&SIP_SVC_PROTO_HEADER_CODE_MASK) << SIP_SVC_PROTO_HEADER_CODE_OFFSET) |           \

          << SIP_SVC_PROTO_HEADER_TRANS_ID_OFFSET) |                                               \
