    intel igb i354 issue with lack of multiqueue (intel atom C2758 board)

    iakovos

      Hi there,

       

      I've been having some trouble getting igb/i354 to enable multiple queues.

       

      Despite compiling the latest igb module (5.2.9.4 at the time of writing this) I have not been able to enable it.

       

      I have ensured that MSI-X interrupts are used, and even set RSS values to 8 (and IntMode to 2 to be safe again) and rebuilt initrd and have googled extensively as well as followed all the information/advice I've seen in intel's documentation for installing the modules. The kernel I am running is 2.6.32 on a proxmox installation (though I tried with a 3.10 kernel as well with same results).

       

      The motherboard is a Supermicro A1SRi-2758F atom server board and there is nothing I can see in the BIOS that looks like it could be causing this issue.

       

      I am starting to think that I am missing something obvious here...

       

      Any help/advice would be much appreciated.

       

      Regards,

       

      Iakovos

          Hi Iakovos -

           

          I am an Intel Applications engineer. Could you please send your information to one of the following for a response:

           

          1) File a bug on the e1000 SourceForge mailing list (e1000.sourceforge.net) or

          2) email Linux-nics@intel.com

           

          Then we should be able to get you some help with your issue.

           

          thanks;

           

          Paul

            Hi Paul,

             

            Many thanks for your reply. It's much appreciated and nice to see that intel employees show interest in customers' problems (makes a nice change sometimes)!

             

            As I needed a working implementation within a certain timeframe I was left with little option but to reinstall using a different distro. My troubleshooting pretty much proved that the issue was related with some options set within the kernels packaged with proxmox. I am afraid I run out of time to troubleshoot this further at this point. At a guess if you had similar hardware at hand you shouldn't have much trouble reproducing the issue

             

            Using the very same driver/module within a debian vanilla kernel (both stable and testing) works a treat. As a matter of fact I had multiqueue support out of the box with the debian kernel with an igb versions of 5.0.5-k (if memory serves) though I compiled the latest version of the module regardless.

             

            I will however make notes of the above information for future reference.

             

            Many thanks for your time,

             

            Iakovos
