mlx5 driver load error

mlx5 driver load error

[Ming Lin]

Hi,

I build k.o/for-4.8 branch(commit fb92d8fb1b9). But mlx5 driver doesn't work.

root@host:~# lspci |grep -i mellanox
03:00.0 Ethernet controller: Mellanox Technologies MT27700 Family [ConnectX-4]
03:00.1 Ethernet controller: Mellanox Technologies MT27700 Family [ConnectX-4]

root@host:~# dmesg |grep -i mlx5
[    3.833348] mlx5_core 0000:03:00.0: firmware version: 12.12.1100
[    4.024478] mlx5_core 0000:03:00.0: enable hca failed
[    4.260086] mlx5_core 0000:03:00.0: mlx5_load_one failed with error code -5

[    4.570046] mlx5_core: probe of 0000:03:00.1 failed with error -5

Could you help on this?

Thanks,
Ming

Hi Ming,
Sorry for slow response,

We tested this commit with this firmware version to eliminate the case
that it is related to FW and it works.

Can you please post your "grep MLX5 .config" output?

Thanks

Hi Ming,

Did you upgrade the Firmware as well?
Did it work before the kernel upgrade?
Do you work in pass-through mode?
Does cold reboot resolve the issue?

Thanks

Hi Ming,

I didn't mean that you need to upgrade the firmware to make this work.
I wanted to understand if alongside with driver upgrade you did a 
firmware upgrade.

The original firmware is 12.12.1100.

12.12.1100 + v4.4 kernel: not work
12.12.1100 + v4.7-rc2 kernel: not work

12.16.1020 + v4.4 kernel: works
12.16.1020 + v4.7-rc2: works
