8. AXGBE Poll Mode Driver
The AXGBE poll mode driver library (librte_pmd_axgbe) implements support for AMD 10 Gbps family of adapters. It is compiled and tested in standard linux distro like Ubuntu.
Detailed information about SoCs that use these devices can be found here:
8.1. Supported Features
AXGBE PMD has support for:
- Base L2 features
- TSS (Transmit Side Scaling)
- Promiscuous mode
- Port statistics
- Multicast mode
- RSS (Receive Side Scaling)
- Checksum offload
- Jumbo Frame up to 9K
8.2. Configuration Information
The following options can be modified in the .config file. Please note that
enabling debugging options may affect system performance.
CONFIG_RTE_LIBRTE_AXGBE_PMD(default y)Toggle compilation of axgbe PMD.
CONFIG_RTE_LIBRTE_AXGBE_PMD_DEBUG(default n)Toggle display for PMD debug related messages.
8.3. Building DPDK
See the DPDK Getting Started Guide for Linux 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 the documentation that comes with DPDK suite.
8.4. Prerequisites and Pre-conditions
- Prepare the system as recommended by DPDK suite.
- Bind the intended AMD device to
igb_uioorvfio-pcimodule.
Now system is ready to run DPDK application.
8.5. Usage Example
Refer to the document compiling and testing a PMD for a NIC for details.
