To bind an Ethernet/Baseband/Crypto device to the VFIO module, you can follow these general steps:
Install the VFIO module on your system if it is not already installed. This module allows you to assign devices to a userspace driver.
Identify the device you want to bind. You can use tools like
lspciorlsusbto list all the PCI or USB devices connected to your system.Determine the kernel driver currently bound to the device by using the following command:
lspci -nnk -s <pci_address>Replace
<pci_address>with the PCI address of your device.Unbind the current driver from the device by writing its driver name (kernel module) into the appropriate file under
/sys/bus/pci/drivers/<driver_name>/unbind. For example:echo "<driver_name>" > /sys/bus/pci/drivers/<driver_name>/unbindVerify that the device is unbound from its previous driver by checking if it is listed under
/sys/bus/pci/drivers/<driver_name>/.Bind (assign) the VFIO-PCI driver to the device by writing its address into a file under
/sys/bus/pci/devices/<device_address>/driver_override. For example:echo "vfio-pci" > /sys/bus/pci/devices/<device_address>/driver_overrideFinally, tell the kernel to re-probe and bind this device to VFIO by writing its address into
/sys/bus/pci/drivers/vfio-pci/bind. For example:echo "<device_address>" > /sys/bus/pci/drivers/vfio-pci/bind
Make sure you have sufficient permissions (such as root or sudo) to perform these operations.
Note: The above steps are general guidelines and may vary based on your specific device, kernel version, and Linux distribution.
