Detailed Description

SiP Service communication protocol request format.

request header

• bits [15: 0] Arm SiP services command code
• bits [23:16] Transaction ID (Filled in by sip_svc service)
• bits [29:24] Unused. Reserved.
• bits [31:30] Arm SiP services communication protocol version

a0 - a7

• User input data to be filled into a0-a7 registers when trigger SMC/HVC

resp_data_addr

• This parameter only used by asynchronous command.
• Dynamic memory address for service to put the asynchronous response data. The service will free this memory space if the client has cancelled the transaction.

resp_data_size

• This parameter only used by asynchronous command.
• Maximum memory size in bytes of resp_data_addr

priv_data

• Memory address to client context. Service will pass this address back to client in response format via callback.
