[Bug 1786902] Re: [18.10 FEAT] SMC-Direct
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786902 Title: [18.10 FEAT] SMC-Direct To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1786902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Applied the list provided, excluding ddb457c6993babbcdd41fca638b870d2a2fc3941, to our unstable (4.18) branch for cosmic. I'm not applying this to 4.17 as I expect the next kernel we upload for cosmic to be based on 4.18. ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: New => Fix Committed ** Changed in: linux (Ubuntu) Assignee: Canonical Kernel Team (canonical-kernel-team) => Seth Forshee (sforshee) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786902 Title: [18.10 FEAT] SMC-Direct To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1786902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

If I omit ddb457c6993b "net/smc: Replace ib_query_gid with rdma_get_gid_attr" all the rest of the commits listed in comment #2 cherry pick cleanly. That commit is later reverted, though intermediate changes make it not a direct revert, but that does make think we can probably just omit it. If I do that I'm left with a net/smc that basically only differs from Linus' master in that it's lacking b4c296f9c964 "RDMA/smc: Replace ib_query_gid with rdma_get_gid_attr" (aside from an include missing in a couple of files).

[Bug 1786902] Re: [18.10 FEAT] SMC-Direct
These do not apply cleanly for me. I don't see git getting confused about deletions, rather I see that we have two or more branches which have merged and have conflicting changes, which doesn't make for easy cherry picks. I'll try to resolve this, but in the mean time I have a couple of questions. When I do 'git log v4.18..master net/smc' using Linus' master at the moment (050cdc6c9501abcd64720b8cc3e7941efee9547d) and compare to the list here, I notice a couple of things. First there's one commit that is missing (ignoring merges): e82f2e31f559 net/smc: optimize consumer cursor updates Should this also be cherry picked or is it unnecessary? The second thing I see is a couple of commits following the ones requested here (ignoring merges): 92f4e77c8591 Revert "net/smc: Replace ib_query_gid with rdma_get_gid_attr" b4c296f9c964 RDMA/smc: Replace ib_query_gid with rdma_get_gid_attr Are these also wanted? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786902 Title: [18.10 FEAT] SMC-Direct To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1786902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

All commits listed apply cleanly, apart from a couple where git (at least for me) gets confused about too many deletions. Forwarding to kernel team for consideration into unstable tree. ** Information type changed from Private to Public ** Description changed: - Provide support for next generation HiperSockets. - SMC-local (Shared Memory Communications -- local) provides a new architecture for high performance networking within a CEC. Buffers in the HSA can be shared between LPARs and will be used for communication. - A new socket family will be used to eliminate TCP overhead.
