| .. _amdgpu_synid8_waitcnt: |
| |
| waitcnt |
| =========================== |
| |
| Counts of outstanding instructions to wait for. |
| |
| The bits of this operand have the following meaning: |
| |
| ============ ====================================================== |
| Bits Description |
| ============ ====================================================== |
| 3:0 VM_CNT: vector memory operations count. |
| 6:4 EXP_CNT: export count. |
| 11:8 LGKM_CNT: LDS, GDS, Constant and Message count. |
| ============ ====================================================== |
| |
| This operand may be specified as a positive 16-bit :ref:`integer_number<amdgpu_synid_integer_number>` |
| or as a combination of the following symbolic helpers: |
| |
| ====================== ====================================================================== |
| Syntax Description |
| ====================== ====================================================================== |
| vmcnt(<*N*>) VM_CNT value. *N* must not exceed the largest VM_CNT value. |
| expcnt(<*N*>) EXP_CNT value. *N* must not exceed the largest EXP_CNT value. |
| lgkmcnt(<*N*>) LGKM_CNT value. *N* must not exceed the largest LGKM_CNT value. |
| vmcnt_sat(<*N*>) VM_CNT value computed as min(*N*, the largest VM_CNT value). |
| expcnt_sat(<*N*>) EXP_CNT value computed as min(*N*, the largest EXP_CNT value). |
| lgkmcnt_sat(<*N*>) LGKM_CNT value computed as min(*N*, the largest LGKM_CNT value). |
| ====================== ====================================================================== |
| |
| These helpers may be specified in any order. 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>`. |
