[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server
but from reading above you hit your targets when explicitly enabling this? so the request is to change LTS expected behavior and possibly introduce regressions to avoid having to explicitly set it?. i still have not seen anything to justify the request, especially as this will filter down in 24.04.3 anyway -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server
Hi Brett, The Cert requirements are hitting 80% of advertised line rate which is largely passable even on noisy networks absent issues with drivers or firmware causing performance issues. In most cases, devices hit 95+ percent so 80 is typically a low bar to meet, but we do occasionally hit cases where devices fail to meet that level of performance. Failures are typically either configuration or hardware issues (in the infrastructure), or driver/firmware issues on the device being tested. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server
why is the expected result 80%? we have historical data that consistently demonstrates this the expectation or its some number we have just decided on? so far this looks to me like a performance enhancement request which we would not do for a stable kernel, especially as there is a viable workaround. if this has been committed upstream it will be in 25.04 and then filter through to 24.04.3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server
Hello Brett, I would like to share the test we performed. 1. When running the certify-ubuntu-server in the Ubuntu Certification Test Suite (iperf3 stress testing), we noticed that the performance results were below expectations. The speed is only about 70% (expected result: over 80%). (attachment: Ubuntu Certification Test Suite failed result ) 2. Upon further investigation, we found that enabling TSO with the command "ethtool -K tx on sg on tso on" restored the system’s LOM performance result to the expected level. (attachment: enabling TSO with the command) 3. Based on the results of the second, we would like these NIC features to be enabled by default, ensuring that users do not have to manually set the configuration every time when they execute this test. And we have found a corresponding patch in the upstream kernel. Would it be possible to consider integrating this patch into the Ubuntu 24.04 server version?

[Bug 2094764] Re: Enable SG/TSO patch backport request for 24.04 server
it is currently not possibly to use ethtool to explicitly enable SG and TSO? the commit mentioned seems to imply that it is? my understanding of the request is to make this the default behavior for the driver, or can you elaborate what the actual issue this is fixing is? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Brett, Thanks for the response. I would like to clarify that this option cannot be configured/tuned by sysadmins. Therefore, only the patch backport to kernel can fixed this issue. Could Canonical assist in integrating this patch into the 24.04 server version? After integrating this patch, we will perform the test and feedback to you.

changing defaults to a stable kernel alters existing expected behaviour and runs the risk of regressions. this option seems to be able to be configured/tuned by sysadmins so does not appear to be critical? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2094764 Title: Enable SG/TSO patch backport request for 24.04 server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2094764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
