Oops sorry, got too excited about verification ;) Thanks for the info. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1709220 Title: RPT related fixes missing in Ubuntu 16.04.3 Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: In Progress Status in linux source package in Zesty: Fix Committed Bug description: == SRU Justification == These four commits are Radix performance patches specific to powerpc. The patches are reported to help anywhere from 40% up to 3.5X on unixbench fork/exec testcases. The first patch was included in mainlne as of 4.12-rc1. The last three patches are still in linux-next. ---Problem Description--- The following patches are missing in the ubuntu 16.04.3 kernel https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156104.html https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/156105.html https://lists.ozlabs.org/pipermail/linuxppc-dev/2017-April/157130.html ---uname output--- 4.10.0-29-generic #33~16.04.1-Ubuntu SMP Tue Jul 25 18:17:06 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux Machine Type = power9 ---Steps to Reproduce--- Did a fork and exec benchmark to look at the performance and they pointed to radix routines.
