FEC_UIO kernel driver not available in imx8mmevk

[Vikas_bansal]

Hi,

I have flashed imx8mmevk with 6.6.3-lts kernel. I have use case to enable dpdk and validate on it.

As per DPDK documentation I tried to use --vdev=net_enetfec and it also loaded pmd it seems as error presented was from enet_uio.c in dpdk driver code.

While from the error it seems device path of uio in /sys/class/uio and /dev/uio is missing. 

I looked for if enet_uio is enabled from config in /proc path and it show the config option for driver was enabled. but I could n't found the .ko file for uio and enet_uio. 

Any suggestion here to enable and run dpdk.

Thanks,

Vikas
