Title:
Make vfio-pci built-in or xhci_hcd optional
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Cosmic:
Opinion
Status in linux source package in Focal:
In Progress
Bug description:
Because of
nazar-pc@nazar-pc ~> cat '/boot/config-4.15.0-21-generic' | grep
CONFIG_USB_XHCI_HCD
CONFIG_USB_XHCI_HCD=y
Following doesn't work:
nazar-pc@nazar-pc ~> cat /etc/modprobe.d/gpu-passthrough.conf
options vfio-pci ids=10de:1b06,10de:10ef,1b21:2142
softdep nouveau pre: vfio-pci
softdep xhci_hcd pre: vfio-pci
GPU is fine (first 2 IDs), but USB controller is always occupied by
xhci_hcd and I can't change that while xhci_hcd is built-in.
I'd like you to resolve this issue by either embedding vfio-pci module
too (prefered solution) or making xhci_hcd optional.
There are some discussions withot clean solution online like this:
