6:4 Optional *operation*.
9:7 Optional *parameters*.
15:10 Unused.
============ ======================================================
This operand may be specified as a positive 16-bit :ref:`integer_number<amdgpu_synid_integer_number>` or using the syntax described below:
======================================== ========================================================================
Syntax Description
======================================== ========================================================================
sendmsg(<*type*>) A message identified by its *type*.
sendmsg(<*type*>, <*op*>) A message identified by its *type* and *operation*.
sendmsg(<*type*>, <*op*>, <*stream*>) A message identified by its *type* and *operation* with a stream *id*.
======================================== ========================================================================
*Type* may be specified using message *name* or message *id*.
*Op* may be specified using operation *name* or operation *id*.
Stream *id* is an integer in the range 0..3.
Message *id*, operation *id* and stream *id* must be specified as positive :ref:`integer numbers<amdgpu_synid_integer_number>`.
Each message type supports specific operations:
