.. ************************************************** * * * Automatically generated file, do not edit! * * * ************************************************** .. _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>`. Examples: .. parsed-literal:: s_waitcnt 0 s_waitcnt vmcnt(1) s_waitcnt expcnt(2) lgkmcnt(3) s_waitcnt vmcnt(1) expcnt(2) lgkmcnt(3) s_waitcnt vmcnt(1), expcnt(2), lgkmcnt(3) s_waitcnt vmcnt(1) & lgkmcnt_sat(100) & expcnt(2)
