WebThis device is behind a PCIe-to-PCI bridge 4, therefore we also need to add device 0000:06:0d.1 to the group following the same procedure as above. Device 0000:00:1e.0 is a bridge that does not currently have a host driver, therefore it’s not required to bind this device to the vfio-pci driver (vfio-pci does not currently support PCI bridges). WebEach UIO device is accessed through a device file and several sysfs attribute files. The device file will be called /dev/uio0 for the first device, and /dev/uio1, /dev/uio2 and so on for subsequent devices. /dev/uioX is used to access the address space of the card.
