After installing the network card driver and DPDK environment, start the dpdk-helloword program, and load the mlx5 program to report an error(安装完网卡驱动和DPDK环境后启动dpdk-helloword程序,加载mlx5程序报错)。
Q:
- What is DevX, can I turn off the function?(DevX是什么功能,我能关闭它吗?)
- How to turn off DevX and what is the impact of it(怎么关闭,关闭了有什么影响?)
- Is there any other solution?(是否有其他解决方案?)
