3.5.8.1.2. Bind the Device
- Install the UIO base module.
$ sudo modprobe uio
- Install uio_igb:
$ sudo insmod ./kernel/linux/igb_uio/igb_uio.ko
- Driver binding:
- To bind the PCIe endpoint device to the UIO Linux kernel driver, run the following commands:
$ cd ../../ $ sudo dpdk-stable/usertools/dpdk-devbind.py -b igb_uio <BDF>
Example:
$ sudo dpdk-stable/usertools/dpdk-devbind.py \ -b igb_uio 01:00.0
- To unbind the PCIe endpoint device from the UIO Linux kernel driver, run the following commands:
$ echo <BDF> | sudo tee /sys/bus/pci/devices/<BDF>/driver/unbind
Example:
$ echo 0000:98:00.0 | sudo tee /sys/bus/pci/devices/0000:98:00.0/driver/unbind
- To bind the PCIe endpoint device to the UIO Linux kernel driver, run the following commands:
