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>`.
