Detailed Description

SiP Services service communication protocol response format.

response header

  • bits [15: 0] Error code
  • bits [23:16] Transaction ID
  • bits [29:24] Unused. Reserved.
  • bits [31:30] Arm SiP services communication protocol version

a0 - a3

  • SMC/HVC return value

resp_data_addr

  • This parameter only used by asynchronous command.
  • Dynamic memory address that put the asynchronous response data. This address is provided by client during request. Client is responsible to free the memory space when receive the callback of a asynchronous command transaction.The memory needs to be dynamically allocated, the framework will free the allocated memory if the channel is in ABORT state.

resp_data_size

  • This parameter only used by asynchronous command.
  • Valid data size in bytes of resp_data_addr

priv_data

  • Memory address to client context which given during request.
