To document the versions used, he is on Ubuntu 19.04 which means we should talking about: DPDK: 18.11-6 (latest LTS) rdma-core (all ib things): 22.1-1 This matches ther versions mentioned in the comments before.
I checked the very recently released 18.11.1 but there was nothing fixed that seems to match this issue. I also checked if I'd have a P9 to test the same, but I don't have one with a MLX5 Card :-/ I agree to Thomas to go to Mellanox experts you might forward the request to rdma-core [1] or dpdk bugtracker [2] and let us know a link to the ML archive or bug to follow. Maybe spawn a bug in DPDK and then a post to rdma referencing to it - so far we just don't know yet on which side to look at it? To get the extra Mellanox experienced eyes on it you could CC (from Maintainers files in rdma and dpdk projects): For RDMA MLX: Jason Gunthorpe <[email protected]> Yishai Hadas <[email protected]> Doug Ledford <[email protected]> For DPDK MLX: Matan Azrad <[email protected]> Shahaf Shuler <[email protected]> Yongseok Koh <[email protected]> I'm not sure if you have taken over from Chao or talk to him anyway, you might add him as well? Chao Zhu <[email protected]> Myself to keep track [email protected] Is this expected to work? Is this in any way Ubuntu (or the combination of software in Ubuntu) specific in your testing? After all you did change the support to Alpha level in [3] right :-) Don't get my feedback above wrong David, I'm happy that somebody picks up and works on DPDK on ppc64 at all again!
