The value must be in the range from 0 to 0xFFFF. 28* A combination of *vmcnt*, *expcnt*, *lgkmcnt* and other values described below. 29 30 ====================== ====================================================================== 31 Syntax Description 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 ====================== ====================================================================== 40 41These values may be specified in any order. Spaces, ampersands, and commas may be used as optional separators. 42If some values are omitted, the corresponding fields will default to their maximum value. 43 44*N* is either an 45:ref:`integer number<amdgpu_synid_integer_number>` or an 46:ref:`absolute expression<amdgpu_synid_absolute_expression>`. 47 48Examples: 49 50.. parsed-literal:: 51 52 vm_cnt = 1 53 exp_cnt = 2 54 lgkm_cnt = 3 55 cnt = vm_cnt | (exp_cnt << 4) | (lgkm_cnt << 8) 56 57 s_waitcnt cnt 58 s_waitcnt 1 | (2 << 4) | (3 << 8) // the same as above 59 s_waitcnt vmcnt(1) expcnt(2) lgkmcnt(3) // the same as above 60 s_waitcnt vmcnt(vm_cnt) expcnt(exp_cnt) lgkmcnt(lgkm_cnt) // the same as above 61 62 s_waitcnt vmcnt(1) 63 s_waitcnt expcnt(2) lgkmcnt(3) 64 s_waitcnt vmcnt(1), expcnt(2), lgkmcnt(3) 65 s_waitcnt vmcnt(1) & lgkmcnt_sat(100) & expcnt(2) 66
