Omni-Path text with link to appear in RHEL release note (corrected)
Incorrect document number in first attachment.
Thank you very much for providing the information. I am adding the note to the RHEL 7.5 Release Notes.
returns 404 - is it expected? Will it be active by or at RHEL 7.5 GA?
Thank you for your cooperation!
Yes, the link will be active at that time, most likely sooner than GA.
Thanks and have a wonderful day!
Thanks for the confirmation!
Have a great day!
We have been contacted by Peter Kjellström in a customer portal discussion thread: https://access.redhat.com/discussions/3390091
I'm not sure whether you can access this, so quoting here:
I downloaded the 7.5beta to see what the state of OPA (Omnipath) support was. Looking at the driver (hfi1.ko) it seems it has seen significant update from 7.4 but there's no mention of it in the "udpated network drivers" section of the release notes.
Maybe this is because the DRIVER_VERSION for that .ko isn't updated correctly? (big diffstat but exactly the same version string...).
My response confirmed unchanged full support but I don't know about the driver version. Can you help me or find somebody who can?
Thank you very much!
Update from Peter:
I did know of the official "fully supported" status but I am a bit confused about the specifics. In the 7.5beta there seems to be a mix of version wrt various components of the Omnipath support...
opa_fm and similar "toolsl" packages: 10.5 (vs latest from Intel-IFS 10.6) libpsm/libfabric: newer version than latest from intel-IFS 10.6 kernel driver: No idea. Many parts seem about as up to date as 10.6 from Intel-IFS, but it's very different..
Maybe you can try to find some clarification on this for us. We're also interested to know who (if anyone) does testing on this combination of components? Presumably Intel tests IFS (currently 10.6).
Could your subject matter experts reply to him? Thank you very much!
I have added John Fleck (SME) to this bug and pointed him to the discussion thread.
"The upstream kernel made us remove the driver version, so we stopped updating it.
It is possible the Red Hat kernel has a “stale” version in it.
We are fully supported in RHEL 7.5."
Please let us know if you need more information.
Lisa and John,
Thanks a lot for your response, I will reply in the discussion.
The RHEL 7.5 GA happens to be today, the Release Notes are live:
but the link to your documentation returns 404. Could you please publish the document asap or send me another link if it has changed?
Thanks a lot!
I apologize for the late response. After troubleshooting this for several days, we discovered that first, it wasn't published and second, the URL I gave you was missing a dash.
Please note that this is the correct link address to use:
Again, I apologize for the delays.
Thanks a lot for the correct link. I have replaced it in the Release Notes and republished the book:
Thanks again for your cooperation!
