[ewg] OFA EWG "OFED next" discussion

[Nikolova, Tatyana E]

Hi Arlin,

I am sorry I missed the meeting today.

I agree with Steve, that we should consider kernel 4.16 or later.

Regards,
Tatyana

Hey Arlin,  I can't make today's call.  I'll reply inline below:

All,

I want to start the discussion on "OFED next" requirements while 4.8-2 is finishing up.
I will start the discussion with the following topics, feel free to add and adjust appropriately.


Which kernel release? (If there is a strong opinion one versus the other please explain):

-  Kernel.org 4.15.8 (stable)

-  Kernel.org 4.16-rc5 (GA most likely early April)



I think we should consider 4.17, which should hit RC1 around 4/15.   If we kept our sparse kernel tree refreshed as the RCs progress, it should be doable.  And it allows OFED to not lag so far behind upstream releases.  My 2 cents...

Or at least 4.16.  I'm not sure why we would consider 4.15.x...



Which distro/backports, do we need to go back 4 years to RH7.0 (2014) and SLES12.0 (2014)?



-  RH 7.5 (beta) - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7-beta/html/7.5_release_notes/index

-  SLES 15 (June 2018) - https://www.suse.com/releasenotes/x86_64/SUSE-SLES/15/

I thought we just supported the last 2 releases or something like that?





Library/ulp/drivers to deprecate:

- Xeon Phi

- ??



Library/ulp/drivers to add:

-  Huawei hns

- ??



Library/ulp/drivers to update:

- rdma-core v17

- ??



Do we have full support for all in-kernel ulp and driver backports?



- NVMe-oF (currently kernel.org only, no backports)

- i40iw  (currently kernel.org only, no backports)

- NFS-rdma (currently SLES12.2 and RH7.3 only)





If we can all participate and provide feedback we can nail down our OFED-next strategy during our upcoming EWG meeting on March 26th.



Thanks,



Arlin
