mlx5_init: IB device not found about aifm HOT 4 CLOSED

There's build option for mlx4 devices in shenango/shared.mk.
Modify it as below and re-build shenango:

CONFIG_MLX5=n
CONFIG_MLX4=y

I'm not sure it's working but you can try.

Thanks for your reply. Before I was able to build successfully, I had modified these places in shenango/shared.mk.
Before modifying, I would get the error as follows:

iokernel/mlx.h:5:10: fatal error: mlx5_custom.h: No such file or directory

Sorry for the late reply. The error is caused by the intermediate mlx5 files left by your first compilation with CONFIG_MLX5=y. You can simply clone a new repo from scratch, set CONFIG_MLX5=n & CONFIG_MLX4=y & CONFIG_DIRECTPATH=n, and recompile.

In addition, our project is mostly implemented using mlx5 NIC and only has limited support for mlx4, so you may observe reduced performance with mlx4. When running the program, you have to delete enable_directpath 1 of all config files in AIFM/aifm/configs/. Please let me know if you have any further questions, I'm happy to answer.
