[Kernel-packages] [Bug 1788098] Re: Avoid migration issues with aligned 2MB THB
I know it's an old bug, but I just want to confirm if my understanding is correct: - You have received all the suggested patchs, via mailing list - Some of them could not be accepted - Paul Mackerras have pointed which patches can be dropped, and which are needed to fix the issue - By above comments, bionic hwe, disco and eoan already contain the patches. - The patches won't be applied in bionic Is the above correct? -- 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/1788098 Title: Avoid migration issues with aligned 2MB THB Status in The Ubuntu-power-systems project: Invalid Status in linux package in Ubuntu: Fix Released Status in qemu package in Ubuntu: Invalid Status in linux source package in Bionic: Won't Fix Status in linux source package in Cosmic: Invalid Status in linux source package in Disco: Fix Released Status in linux source package in Eoan: Fix Released Status in qemu source package in Eoan: Invalid Bug description: FYI: This blocks bug 1781526 - once this one here is resolved we can go on with SRU considerations for 1781526 --- Comment From jhop...@us.ibm.com 2018-08-20 17:12 EDT--- Hi, in some environments it was observed that this qemu patch to enable THP made it more likely to hit guest migration issues, however the following kernel patch resolves those migration issues: https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next=c066fafc595eef5ae3c83ae3a8305956b8c3ef15 KVM: PPC: Book3S HV: Use correct pagesize in kvm_unmap_radix() Once merged upstream, it would be good to include that change as well to avoid potential migration problems.
