------- Comment From jhop...@us.ibm.com 2017-08-10 10:41 EDT------- Aneesh has additional Radix performance fixes (3 more total):
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=424de9c6e3f89399fc11afc1f53f89c5329132da ("powerpc/mm/radix: Avoid flushing the PWC on every flush_tlb_range") . https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=a46cc7a90fd8d95bfbb2b27080efe872a1a51db4 ("powerpc/mm/radix: Improve TLB/PWC flushes") . https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=5ce5fe14ed0302315061cf97ce67accd1b25b938 ("powerpc/mm/radix: Improve _tlbiel_pid to be usable for PWC flushes") (upstream, currently scheduled for 4.14) Can these be included in Zesty as well? FYI the first set of 3 patches mentioned in the orig bug report helps anywhere from 40% up to 3.5X on unixbench fork/exec testcases. I will post updated numbers for this second set of 3 fixes soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1709220 Title: RPT related fixes missing in Ubuntu 16.04.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1709220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
