+    ============ ======================================================
+    Bits         Description
+    ============ ======================================================
+    3:0          Message *type*.
+    6:4          Optional *operation*.
+    9:7          Optional *parameters*.
+    15:10        Unused.
+    ============ ======================================================
+

+    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:
