so, apparently there is no driver for the mellanox connectx-4 100g ethernet cards, nvidia did not release a driver for arch or similar, and I’m at a loss for how to get them to be recognized and usable, since nothing seems to be written, that I can find at least, for arch/EOS, can anyone offer help? I have two connectx-4 cards, and a switch, and everything else needed but the dang driver to get it to initialize in EOS….
I’ve never heard of that ethernet card brand before. But I did run across this:
Getting started with ConnectX-4 100Gb/s Adapter for Linux
No idea if it will help in your situation or not. Good luck! 
trying to follow that does not help sadly, its a guide written for centos and needs the RPM system which, supposedly exists in arch from what I can find on google, but running the install script fails and I am NOT savvy enough to edit that thing to get it to work, so I”m still in the same boat sadly, but thank you, I had not stumbled on that particular one yet, though it lends the same end result of not installing.
1 Like
I can finally add that I made SOME progress due to not realizing I needed to add a tool to get it to be recognized by the system, so progress, and new errors, on two different systems running EOS. one step forward and another brick wall to the face.

TLDR it seems the installer’s failing because of not finding some file called nnt_ioctl.h??? emphasis on SEEMS, I am by no means confident that’s the problem. its A problem though.
Its datacenter gear so I’m not suprised Nvidia does not offer support for Arch. There is a mellanox firmware package, I assume you tried that? I agree that compilation fails because nnt_ioctl.h is not present.
that sadly did not change anything, I keep seeing that folk are saying compile from source, but dangit every attempt to do so fails saying unsupported distro, yeah no kidding that’s why I’m trying to compile it dangit, and the flags suggested do not work ( - - ignore-distro-check and - - add-kernel-support both get stated as not valid flags to try and force it to compile FOR arch/EOS), so I’m left with the source files complaining its unsupported, again no kidding, and am unable to do anything WITH the source files I’m supposed to compile from. I feel like I’m beating myself with a brick trying to figure this out, it is madness.
I get it, it’s frustrating. Lets start with basic debugging? What exactly is the issue? Are the cards not recognized by the system? What does lspci -nn | grep Mellanox return?
Have you tried mstflint? It is available in the AUR. There is also a thread in the Arch forum about trying to compile an older version of the driver you need: https://bbs.archlinux.org/viewtopic.php?id=263457
the card is physically seen, but I cannot seem to figure out, and maybe its due to lack of actual knowledge what the heck I’m doing here, I cannot rule that out, how to get it to show up in the network manager so that I can configure it as an interface for networking, which seems to be from what little I can tell and I am entirely possible to be mistaken here, but what little I THINK I understand, it needs the mellanox OFED driver to be able to configure it in the network manager, due to particular binary files used to set the thing up, and though I’m blanking on which commands it was I tried to run exactly, some work and others do not, so it appears I have a partially working setup, but still wonderfully incomplete, the cards DO show up, on both pcs, but neither can actually do anything with them, and for what ever its worth, I’m testing this FIRST on a single pc and then plan to try and replicate “whatever works” on the other once I get there first.
if I recall, mstfint IS installed, but I’m going to confirm that right quick. nope, seems I’m thinking of something else, MSTFLINT is NOT installed, and I typed it out in caps because I cant see for squat so that’s more for my own use than anything. ah cool, installing it errors out and stops the installer. exit status 4. configure : error: cannot find infiniband/mad.h
EDIT: before I forget since I’m so heavily prone to that with my ADHD….thank you all, everyone on this forum that spends their time to try and help users like me, you all are god-sends, thank you. I don’t post here often, but every time I do, some kind soul has helped me to fix the issues, so thank you.
You’re welcome 
Also, thank you for not taking quick help for granted. Happens all to often nowadays.
That’s… something? Can you paste the output of lsmod | grep mlx5? And please past it in a markdown quote block so it’s easier to read 
The output of ip linkcould also be useful
is the mlx5 specific to connectx 5? I have connectx4 cards is why I ask, IE that said do I need to use lsmod | grep mlx4 instead? also I keep wondering what to use for posting the massive text walls but being unfamiliar with this site’s setup just yet, I’m used to code blocks as an option for that. I’ll do that going forward thank you for that specific suggestion. also should I do so for both systems, or just the main one I’m trying to use to test this with?
also I might be having a moment of dumb, but how do I setup the process of marking something in markdown, like what’s the tags to use? I can guess but it’d be easier to just outright ask how to set that up, IE how to make the tags, example < HTML > for making a web file, then < /HTML > as an example of what I’m trying to ask.
edit: seems mlnx4 doesn’t exist. output is
[volt@Editing-PC Pictures]$ lsmod | grep mlx
mlx5_ib 589824 0
macsec 69632 2 atlantic,mlx5_ib
ib_uverbs 217088 1 mlx5_ib

tls 155648 1 mlx5_core
ptp 45056 3 atlantic,igb,mlx5_core
pci_hyperv_intf 12288 1 mlx5_core
and now I went and made it weird by editing the post with the info instead of replying, works either way.
The main system should be enough. I personally think markdown blocks make reading preformatted text easier, that’s why I asked for it 
How about you do lsmod | grep mlx without a number, this way, the number doesnt matter.
Markdown codeblocks are made by three backticks like this:
```
(markdown here)
```
Don’t worry. Could you post the output of ip link as well?
right, forgot about that one, thanks.

Alright. lsmod shows the drivers are loaded, and ip link shows two Ethernet interfaces, one down, one up. I assume the interface which is down (eth1) is your Mellanox card, since you use the other one two answer me?
Do you have a compatible ethernet cable in the card? Seems like you need a QSFP28 cable/adapter.
no, the one that shows as up is my motherboards onboard ethernet port. I cant get the mellanox card to show in that list which is also what shows in the network manager application, but not the mellanox card, so that list from ip link is what shows in the network manager, and the mellanox card is not one of them.
I’ve not bothered plugging in the optics I have yet since I cant even get the thing to show up to try and assign an IP address of my choosing.
Okay I get it.
Can you post the output of sudo dmesg | grep mellanox (or sudo dmesg | grep mlx) if the former doesn’t output anything at all. That might show us some errors.
the first outputs nothing, the second gives some output.

yeah, sorry, doing stuff on that pc, so I’m replying from the other so I can see when you all make a post and then editing outputs accordingly, not doing this every time, but this time I did.

This output looks completely fine. Please go ahead and plugin the Ethernet, maybe connect it to a running switch if you can etc. I still haven’t seen an issue
