Nice! -- 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/1857040 Title: zfs: upstream support for hardware-accelerated encryption Status in linux package in Ubuntu: In Progress Bug description: I understand that in Linux 5.0+, certain encryption-related symbols have been marked GPL-only, making them unavailable for use by zfs. As a result, using encryption in zfs pools increases cpu load / decreases disk throughput. There are a pair of upstream pull requests that should improve the performance (with performance measurement done on x86-64). Can these be pulled into the Ubuntu kernel? https://github.com/zfsonlinux/zfs/pull/9515 https://github.com/zfsonlinux/zfs/pull/9296 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1857040/+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
