Mellanox ConnectX/X2/X3 OFED module for FreeBSD 11.x

[Frank DiMitri]

Meny,



Amazingly enough I completely missed that, and nobody was able to point me to them. I was unaware of any in-tree Mellanox drivers.



My (embarrassing) mistake, glad to see they're in the kernel by default.



Thanks!

Hi, 

 

 

 

Not sure how did you reach that conclusion. 

 

 

 

We have an updated 11.x inbox driver for ConnectX-3 under /sys/ofed/ 

 

 

 

Eth: /sys/ofed/drivers/net/mlx4 

 

InfiniBand: /sys/ofed/drivers/infiniband/.. 

 

 

 

We have recently (12-CURRENT) moved the ConnectX-3 driver to /sys/dev 

 

 

 

We'll be happy to assist in case you have more questions.

Mellanox has no driver for cards earlier than ConnectX4 available for FreeBSD 11.x at the moment. 

 

 

 

 

 

 

 

What I have right now is a quick hack to get the 2.1.6 driver for 10.1 to compile and work under 11.0. It needs some polishing, but it does work. I didn't do anything for the InfiniBand side, only the Ethernet/core.

For anyone looking to run these cards under FreeBSD 11.0, this should work at the least in the interim. The only non-functional part under 11.0-release-p1 are the counters available through sysctl (hw.mlxenX.stat) for packet sizes ie in_gt_1548. 

 

 

 

 

 

 

 

Hopefully this is the right place to send this. 

 

 

 

 

 

 

 

Is there a reason the OFED drivers aren't in-tree? They are dual-licensed under GPL and BSD. 

 

 

 

 

 

 

 

Thanks,
