36 Pre-Installation Configuration
37 ------------------------------
42 The following build-time options may be enabled on build time using.
44 ``-Dc_args=`` meson argument (e.g. ``-Dc_args=-DRTE_LIBRTE_TXGBE_DEBUG_RX``).
46 Please note that enabling debugging options may affect system performance.
48 - ``RTE_LIBRTE_TXGBE_DEBUG_RX`` (undefined by default)
50 Toggle display of receive fast path run-time messages.
52 - ``RTE_LIBRTE_TXGBE_DEBUG_TX`` (undefined by default)
54 Toggle display of transmit fast path run-time messages.
56 - ``RTE_LIBRTE_TXGBE_DEBUG_TX_FREE`` (undefined by default)
58 Toggle display of transmit descriptor clean messages.
60 Dynamic Logging Parameters
61 ~~~~~~~~~~~~~~~~~~~~~~~~~~
63 One may leverage EAL option "--log-level" to change default levels
64 for the log types supported by the driver. The option is used with
65 an argument typically consisting of two parts separated by a colon.
67 TXGBE PMD provides the following log types available for control:
69 - ``pmd.net.txgbe.driver`` (default level is **notice**)
71 Affects driver-wide messages unrelated to any particular devices.
73 - ``pmd.net.txgbe.init`` (default level is **notice**)
75 Extra logging of the messages during PMD initialization.
77 Driver compilation and testing
