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.
