原因分析

以上报错场景，可能的原因如下：

• 报错现象一：可能为驱动入队地址非法。对应plog如下：

  [ERROR] DRV(3078,python3):2023-04-27-20:04:09.700.666 [ascend][curpid: 3078, 3420][drv][queuemng][QueueIoctl 133]Ioctl failed. (cmd=40585102; error=0; ret=58)

• 报错现象二：可能为HDC通道断链导致Host数据发送异常。对应plog记录如下：

  [ERROR] DRV(253915,python3):2023-05-16-22:35:00.917.147 [ascend][curpid: 253915, 254303][drv][queuemng][QueueIoctl 133]Ioctl failed. (cmd=40585102; error=0; ret=27)

• 报错现象三：可能为PCIE链路异常导致发起DMA拷贝失败。对应plog记录如下：

  [ERROR] RUNTIME(179263,python3):2023-05-17-09:35:01.035.824 [npu_driver.cc:3205]179650 MemQueueEnQueueBuff:report error module_type=1, module_name=EL9999

• 报错现象四：可能为DEVICE侧CP进程异常导致H2D拷贝失败。对应plog如下：

  [ERROR] DRV(2622,python3):2023-05-17-10:05:11.057.003 [ascend][curpid: 2622, 3009][drv][queuemng][QueueIoctl 133]Ioctl failed. (cmd=40585102; error=0; ret=16)
