[Bug 1535045] Re: Biosdevname does not provide interface naming information for ConnecX4 Devices

[Jeff Lane]

Hi Talat. Have you built the current upstream version 0.7.3 and tried it
to verify that has the CX4 support?

I'm working a bit on this to see if I can get this bug rolling again,
but it would help to know for sure that the updated version does show
the info you need it to show.

I'll also try to test this today (I "think" I have a CX4 card, but I'm
not positive on that, I need to dig through our lab machines to see what
the Mellanox cards actually are).


for notes: The upstream source for this is

Title:
  Biosdevname does not provide interface naming information for ConnecX4
  Devices

Status in biosdevname package in Ubuntu:
  In Progress

Bug description:
  Hi,

  Biosdevname is enabled by default for ubuntu14.04.4, 
  We see that the ConnectX3 interface name is pXpX and ConnectX4 interfaces is ethX
  when biosdevname is enabled we should see all the interfaces like pxpX

  As for biosdevname user manual :
  when we ran #biosdevname -i <interface name> , it should return the interface biosdevname
  the command exit code should return 0 for success 
  see it in the link :http://linux.die.net/man/1/biosdevname.

  When we run biosdevname on ConnectX4 interface we get return status 2.

  could you please add support for ConnectX4 devices ?

  Exit Codes

  Returns 0 on success, with BIOS-suggested name printed to stdout.
  Returns 1 on provided device name lookup failure.
  Returns 2 if system BIOS does not provide naming information. biosdevname requires system BIOS to provide naming information, either via SMBIOS or sysfs files.
  Returns 3 if not run as root but requires root privileges.
  Returns 4 if running in a virtual machine.
