A big thank you for your help with in moving this forward. Appreciate all the effort that has gone into it. Hopefully I can answer several of your questions and alleviate your concerns. First let me paint the overall picture and answer some of the specifics later. Our team has been active in the community for a few months and have been submitting several patches to bring Power on par with other architectures. In fact just today we got an ack for one of the outstanding issues. That should clear the way for acceptance of the entire patch set upstream. Right now our focus is the Mellanox adapter and that is why we requested support in Ubuntu 16.10 with MLNX_OFED. We hope to be able to remove that limitation in a future Ubuntu release. If it is acceptable, we would like to suggest the following steps: 1. Start with Ubuntu 16.10 Tech Preview and support only Mellanox adapter (requires MLNX_OFED) 2. In Ubuntu 17.04 expand the Tech Preview to include additional adapters 3. Lift the Tech preview in 17.10 That should hopefully erase some of the concerns and ease acceptance. We are committed to supporting DPDK on Power. > Hi, > thanks for testing, sad that there could have been no HW test and also that > it was only testpmd. We have been working with upstream DPDK 16.07 and have locally tested ip_pipeline and other tests as well. We have tested the LPM and ACL libraries as well. Once the patches go upstream (as mentioned previously), these can be pulled into Ubuntu 16.10 as well. One of the things we discovered during the course of our testing is that package ovs-dpdk has not been enabled on Power in the ppa. > I think it is time to discuss what we do about your request to have it as > "tech preview only". > > To my knowledge there is no such thing as a tech preview per package (please > correct me if I'm wrong).

The Tech Preview request is only for DPDK on Power in Ubuntu 16.10. Previous responses should help ease your concerns. > > I'd currently prefer to decline the inclusion for the following reasons: > - power8 dpdk upstream work is still on the old state of dpdk 2.2 (see the > example with the broken default config) We have been working with upstream DPDK 16.07 as mentioned > - power still disables many devices since they are not tested properly > - the devices you requested yourself (mlx) are actually unusable in a > Distribution environment I understand some of your concerns. It is precisely to facilitate thorough testing that we are requesting a Tech Preview. The request is to release note it with a "Tech Preview" label only for the Mellanox devices. In this way, a customer will not attempt to use other devices. > - there is not a lot of test exposure on power yet, nor upstream focus > > If we would put it into 16.10 archive as is this would mean > Canonical will have to > - Add the delta to packaging > - add release notes entry about "tech preview" only status > - carry changes into deb_dpdk packaging > But if we do so, that implies several todos and especially serious > commitment for IBM > - stabilize dpdk on power upstream > - take over responsibility the power related issues for the 16.10 support > time Yes, we do understand the commitment required from IBM and previous responses should provide the assurance you are seeking. > > I'm afraid if we pick it up now it might end up carrying this as "preview" > forever and it will become a maintenance burden.

That would be our preference. This will also enable additional run time outside of IBM. Please let us know what you think, and what are the next steps moving forward. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539775 Title: Enable ppc64el on dpdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpdk/+bug/1539775/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
