https://bugzilla.kernel.org/show_bug.cgi?id=218876 --- Comment #7 from TJ (linux@xxxxxx) --- I've done some basic analysis and testing here to develop a udev rule. This looks like it ought to do the job. # this is /etc/udev/rules.d/00-vfiio-pci.rules SUBSYSTEM=="pci", ATTR{endor}=="1912", ATTR{device}=="0014", RUN+="modprobe vfio-pci ids=1912:0014" It needs testing so what I'd suggest is: 1. use the unbind method in (2) in my previous comment to detach the xhci_hcd driver and check there is no "Kernel driver in use" with: $ lspci -nnk -d 1912:0014" 2. Tell the kernel to replay events to test if the rule reacts as expected: # udevadm trigger --type=subsystems --subsystem-match=pci 3. Check if VFIO bound to the device ("Kernel driver in use") with: $ lspci -nnk -d 1912:0014" If that works then the module and rule need adding to the initrd.img with: # echo "vfio-pci" >> /etc/initramfs-tools/modules # update-initramfs -u and then do a reboot test when convenient. -- You may reply to this email to add a comment.
