8 .. _amdgpu_synid9_waitcnt:
11 ===========================
13 Counts of outstanding instructions to wait for.
15 The bits of this operand have the following meaning:
17 ========== ========= ================================================ ============
18 High Bits Low Bits Description Value Range
19 ========== ========= ================================================ ============
20 15:14 3:0 VM_CNT: vector memory operations count. 0..63
21 \- 6:4 EXP_CNT: export count. 0..7
22 \- 11:8 LGKM_CNT: LDS, GDS, Constant and Message count. 0..15
23 ========== ========= ================================================ ============
25 This operand may be specified as one of the following:
27 * 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.
28 * A combination of *vmcnt*, *expcnt*, *lgkmcnt* and other values described below.
30 ====================== ======================================================================
32 ====================== ======================================================================
33 vmcnt(<*N*>) A VM_CNT value. *N* must not exceed the largest VM_CNT value.
34 expcnt(<*N*>) An EXP_CNT value. *N* must not exceed the largest EXP_CNT value.
35 lgkmcnt(<*N*>) An LGKM_CNT value. *N* must not exceed the largest LGKM_CNT value.
36 vmcnt_sat(<*N*>) A VM_CNT value computed as min(*N*, the largest VM_CNT value).
37 expcnt_sat(<*N*>) An EXP_CNT value computed as min(*N*, the largest EXP_CNT value).
38 lgkmcnt_sat(<*N*>) An LGKM_CNT value computed as min(*N*, the largest LGKM_CNT value).
39 ====================== ======================================================================
41 These values may be specified in any order. Spaces, ampersands and commas may be used as optional separators.
44 :ref:`integer number<amdgpu_synid_integer_number>` or an
45 :ref:`absolute expression<amdgpu_synid_absolute_expression>`.
