.. _amdgpu_synid_gfx11_msg_e37f7b:
msg
===
A 16-bit message code. The bits of this operand have the following meaning:
============ =============================== ===============
Bits Description Value Range
============ =============================== ===============
3:0 Message *type*. 0..15
6:4 Optional *operation*. 0..7
7:7 Must be 0. 0
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 from 0 to 0xFFFF.
* A *sendmsg* value which is 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 from 0 to 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:
====================== ========== ============================== ============ ==========
Message name Message Id Supported Operations Operation Id Stream Id
====================== ========== ============================== ============ ==========
MSG_INTERRUPT 1 \- \- \-
MSG_HS_TESSFACTOR 2 \- \- \-
MSG_DEALLOC_VGPRS 3 \- \- \-
MSG_STALL_WAVE_GEN 5 \- \- \-
MSG_HALT_WAVES 6 \- \- \-
MSG_GS_ALLOC_REQ 9 \- \- \-
MSG_SYSMSG 15 SYSMSG_OP_ECC_ERR_INTERRUPT 1 \-
\ SYSMSG_OP_REG_RD 2 \-
\ SYSMSG_OP_TTRACE_PC 4 \-
====================== ========== ============================== ============ ==========
*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 the corresponding value range (see the first table).
Examples:
.. parsed-literal::
// numeric message code
msg = 0x10
s_sendmsg 0x12
s_sendmsg msg + 2
// sendmsg with strict arguments validation
s_sendmsg sendmsg(MSG_INTERRUPT)
s_sendmsg sendmsg(MSG_SYSMSG, SYSMSG_OP_TTRACE_PC)
// sendmsg with validation of value range only
msg = 2
op = 3
s_sendmsg sendmsg(msg, op)
