- Follow the DPDK :ref:`Getting Started Guide for Linux <linux_gsg>` to setup the basic DPDK environment.
Pre-Installation Configuration
------------------------------
Build Options
~~~~~~~~~~~~~
The following build-time options may be enabled on build time using.
``-Dc_args=`` meson argument (e.g. ``-Dc_args=-DRTE_LIBRTE_TXGBE_DEBUG_RX``).
Please note that enabling debugging options may affect system performance.
- ``RTE_LIBRTE_TXGBE_DEBUG_RX`` (undefined by default)
Toggle display of receive fast path run-time messages.
- ``RTE_LIBRTE_TXGBE_DEBUG_TX`` (undefined by default)
Toggle display of transmit fast path run-time messages.
- ``RTE_LIBRTE_TXGBE_DEBUG_TX_FREE`` (undefined by default)
Toggle display of transmit descriptor clean messages.
Dynamic Logging Parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~
One may leverage EAL option "--log-level" to change default levels
for the log types supported by the driver. The option is used with
an argument typically consisting of two parts separated by a colon.
TXGBE PMD provides the following log types available for control:
- ``pmd.net.txgbe.driver`` (default level is **notice**)
Affects driver-wide messages unrelated to any particular devices.
- ``pmd.net.txgbe.init`` (default level is **notice**)
Extra logging of the messages during PMD initialization.
Driver compilation and testing
