[Kernel-packages] [Bug 1585850] Re: [Bug]KNL:Spread MWAIT cache lines over all nodes
** Changed in: intel Status: New => Fix Released -- 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/1585850 Title: [Bug]KNL:Spread MWAIT cache lines over all nodes Status in intel: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Status in linux source package in Yakkety: Fix Released Bug description: KNL sees severely degraded memory bandwidth on MCDRAM with C-states deeper than C1 and with sub numa clustering enabled. This has been root caused to all idle task's MWAIT cache line placed in node 0. Node 0's CHA goes into degraded mode because the many MWAIT lines overflow an internal hash table. Fix is to allocate the idle task's task structs on their respective nodes. The fix patch is merged into linux-next and will be part of v4.7, please back port into 16.04 kernel: 725fc62 kernek/fork.c: allocate idle task for a CPU always on its local node To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1585850/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp

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- xenial' to 'verification-done-xenial'. 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.
