.. _amdgpu_synid_waitcnt:

waitcnt
=======

Counts of outstanding instructions to wait for.

The bits of this operand have the following meaning:

   ===== ================================================ ============
   Bits  Description                                      Value Range
   ===== ================================================ ============
   2:0   EXP_CNT: export and LDSDIR count.                0..7
   3:3   Unused                                           \-
   9:4   LGKM_CNT: LDS, GDS, Constant and Message count.  0..63
   15:10 VM_CNT: vector memory operations count.          0..63
   ===== ================================================ ============

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 combination of *vmcnt*, *expcnt*, *lgkmcnt* and other values described below.

    ====================== ======================================================================
    Syntax                 Description
    ====================== ======================================================================
    vmcnt(<*N*>)           A VM_CNT value. *N* must not exceed the largest VM_CNT value.
    expcnt(<*N*>)          An EXP_CNT value. *N* must not exceed the largest EXP_CNT value.
    lgkmcnt(<*N*>)         An LGKM_CNT value. *N* must not exceed the largest LGKM_CNT value.
    vmcnt_sat(<*N*>)       A VM_CNT value computed as min(*N*, the largest VM_CNT value).
    expcnt_sat(<*N*>)      An EXP_CNT value computed as min(*N*, the largest EXP_CNT value).
    lgkmcnt_sat(<*N*>)     An LGKM_CNT value computed as min(*N*, the largest LGKM_CNT value).
    ====================== ======================================================================

These values may be specified in any order. Spaces, ampersands and commas may be used as optional separators.

*N* is either an
:ref:`integer number<amdgpu_synid_integer_number>` or an
:ref:`absolute expression<amdgpu_synid_absolute_expression>`.

Examples:

.. parsed-literal::

    s_waitcnt vmcnt(1)
    s_waitcnt expcnt(2) lgkmcnt(3)
    s_waitcnt vmcnt(1), expcnt(2), lgkmcnt(3)
    s_waitcnt vmcnt(1) & lgkmcnt_sat(100) & expcnt(2)
