A 16-bit message code. The bits of this operand have the following meaning:
|
|
|
|
============ =============================== ===============

|
|
============ =============================== ===============
|
|

|
|
6:4 Optional *operation*. 0..7
|

7:7 Unused. \-
|
|
9:8 Optional *stream*. 0..3
|
|
15:10 Unused. \-

|
============ =============================== ===============
|
|
|
|
This operand may be specified as one of the following:
|
|
|
|
* An :ref:`integer_number<amdgpu_synid_integer_number>` or an :ref:`absolute_expression<amdgpu_synid_absolute_expression>`. The value must be in the range 0..0xFFFF.
|
|
* A *sendmsg* value described below.

Sendmsg Value 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.
|
|
|
|
Numeric values may be specified as positive :ref:`integer numbers<amdgpu_synid_integer_number>`
|
|
or :ref:`absolute expressions<amdgpu_synid_absolute_expression>`.
|
|
|
|
Each message type supports specific operations:

*Sendmsg* arguments are validated depending on how *type* value is specified:
|
|
|
|
* If message *type* is specified by name, arguments values must satisfy limitations detailed in the table above.
|
|
* If message *type* is specified as a number, each argument must not exceed corresponding value range (see the first table).
