Building DPDK
|
|
-------------
|
|
|
|
See the :ref:`DPDK Getting Started Guide for Linux <linux_gsg>` for
|
|
instructions on how to build DPDK.
|
|
|
|
By default the AXGBE PMD library will be built into the DPDK library.
|
|
|
|
For configuring and using UIO frameworks, please also refer :ref:`the
|
|
documentation that comes with DPDK suite <linux_gsg>`.
|
|
|
|
|
|
Prerequisites and Pre-conditions
|
|
--------------------------------
|
|
- Prepare the system as recommended by DPDK suite.
|
|
|
|
- Bind the intended AMD device to ``igb_uio`` or ``vfio-pci`` module.
|
|
|
|
Now system is ready to run DPDK application.
|
|
|
|
|
|
