| 26 | ======================================== ======================================================================== |
| 27 | Syntax Description |
| 28 | ======================================== ======================================================================== |
| 29 | sendmsg(<*type*>) A message identified by its *type*. |
| 30 | sendmsg(<*type*>, <*op*>) A message identified by its *type* and *operation*. |
| 31 | sendmsg(<*type*>, <*op*>, <*stream*>) A message identified by its *type* and *operation* with a stream *id*. |
| 32 | ======================================== ======================================================================== |
| 33 | |
| 34 | *Type* may be specified using message *name* or message *id*. |
| 35 | |
| 36 | *Op* may be specified using operation *name* or operation *id*. |
| 37 | |
| 38 | Stream *id* is an integer in the range 0..3. |
| 39 | |
| 40 | Message *id*, operation *id* and stream *id* must be specified as positive :ref:`integer numbers<amdgpu_synid_integer_number>`. |
| 41 | |
| 42 | Each message type supports specific operations: |
