These patches include - - New Hyper-V IOMMU driver. This driver will be Hyper-V specific. - Minor update to the Hyper-V specific virtual PCI code. Need to expand the size of an array to allow for a larger number of vCPUs. There are very large VM instance sizes coming to Azure in 2019, and Ubuntu will require the following patches in order to function properly: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git/commit/?id=29217a4746835fef35279abbd12c1a1efe83bfca https://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git/commit/?id=84fdfafab849036b5aefa52824b5cb42e887ef0e https://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git/commit/?id=c8ccf7599ddac5fa48e06104c44b24709e21eed5 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/pci/controller /pci-hyperv.c?id=9bc1174280ddf7693e8c29a8f1743809e987ac37 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-azure/+bug/1826447/+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
