核切换

参考以下操作可将当前聚焦的核切换至指定的核，切核后会自动展示指定核代码中断处的位置。

• 如果当前运行的核为aiv的“core 2”，指定切换的核为aiv的“core 3”。

  (msdebug) ascend aiv 3
  [Switching to focus on Kernel matmul_leakyrelu_custom, CoreId 3, Type aiv]
  * thread #1, name = 'matmul_leakyrel', stop reason = breakpoint 1.1
      frame #0: 0x000000000000fd3c device_debugdata`_ZN7AscendC13WaitEventImplEt_mix_aiv(flagId=1) at kernel_operator_sync_impl.h:142:5
     139
     140  __aicore__ inline void WaitEventImpl(uint16_t flagId)
     141  {
  -> 142      wait_flag_dev(flagId);
     143  }
     144
     145  __aicore__ inline void SetSyncBaseAddrImpl(uint64_t config)

  完成切换后，再次查询核信息可看到已切换至新指定的核id所在行。

  (msdebug) ascend info cores
    CoreId  Type  Device Stream Task Block         PC               stop reason
     17     aic      1     3     0     0     0x12c0c00f1f88         breakpoint 1.1
      2     aiv      1     3     0     0     0x12c0c00f8fbc         breakpoint 1.1
  *   3     aiv      1     3     0     0     0x12c0c00f8d3c         breakpoint 1.1

• 如果当前运行的核为aiv的“core 3”，指定切换的核为aic的“core 17”。

  (msdebug) ascend aic 17
  [Switching to focus on Kernel matmul_leakyrelu_custom, CoreId 17, Type aic]
  * thread #1, name = 'matmul_leakyrel', stop reason = breakpoint 1.1
      frame #0: 0x0000000000008f88 device_debugdata`_ZN7AscendC7BarrierEv_mix_aic at kfc_comm.h:39
     36
     37   namespace AscendC {
     38   __aicore__ inline void Barrier()
  -> 39   {
     40   #if defined(__CCE_KT_TEST__) && __CCE_KT_TEST__ == 1
     41       __asm__ __volatile__("" ::: "memory");
     42   #else

  完成切换后，再次查询核信息可看到已切换至新指定的核id所在行。

  (msdebug) ascend info cores
    CoreId  Type  Device Stream Task Block         PC               stop reason
  *  17     aic      1     3     0     0     0x12c0c00f1f88         breakpoint 1.1
