I also get this issue, but with the -realtime kernel. Linux version 6.8.1-1026-realtime (buildd@lcy02-amd64-061) (x86_64-linux-gnu-gcc-13 (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0
Intel E810-C NIC. I tried a couple different ice driver versions. EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized EAL: Using IOMMU type 1 (Type 1) EAL: Getting a vfio_dev_fd for 0000:01:11.0 failed -- 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/2118903 Title: Cannot use VFs with DPDK on Ubuntu kernels Status in linux package in Ubuntu: Fix Released Bug description: When running DPDK on Ubuntu, we can no longer use virtual function (VF) devices. VFIO framework is giving errors. Tested with Intel E810 and XL710 NICs. After creating a VF on each NIC, and then binding those NICs to vfio- pci for DPDK use as normal, when we actually try running DPDK to use those NICs, we get the error e.g "Getting a vfio_dev_fd for 0000:41:01.0 failed". This error is due to a failure of ioctl() call "VFIO_GROUP_GET_DEVICE_FD" on the vfio group for the VF device. Thus far, we have only been able to reproduce this issue with Ubuntu kernels. While far from a kernel expert, and so may have missed some settings, the follow are what has been tested: * Ubuntu kernels shipped with Ubuntu 25.04 - FAIL * Using a kernel built from latest kernel.org source - WORKS ok * Using a 6.14 stock kernel build from kernel.org sources - WORKS ok * Using a stock kernel built using the config copied from the 6.14 Ubuntu source package - WORKS ok * Manually built kernel using the 6.14 Ubuntu sources [tested with the VFIO_DEVICE_CDEV on and off] - FAIL * Using an Ubuntu-mainline-kernel package 6.15.8-061508-generic - WORKS ok To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2118903/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
