42 Pre-Installation Configuration
43 ------------------------------
48 The following build-time options may be enabled on build time using.
50 ``-Dc_args=`` meson argument (e.g. ``-Dc_args=-DRTE_LIBRTE_TXGBE_DEBUG_RX``).
52 Please note that enabling debugging options may affect system performance.
54 - ``RTE_LIBRTE_TXGBE_DEBUG_RX`` (undefined by default)
56 Toggle display of receive fast path run-time messages.
58 - ``RTE_LIBRTE_TXGBE_DEBUG_TX`` (undefined by default)
60 Toggle display of transmit fast path run-time messages.
62 - ``RTE_LIBRTE_TXGBE_DEBUG_TX_FREE`` (undefined by default)
64 Toggle display of transmit descriptor clean messages.
66 Dynamic Logging Parameters
67 ~~~~~~~~~~~~~~~~~~~~~~~~~~
69 One may leverage EAL option "--log-level" to change default levels
70 for the log types supported by the driver. The option is used with
71 an argument typically consisting of two parts separated by a colon.
73 TXGBE PMD provides the following log types available for control:
75 - ``pmd.net.txgbe.driver`` (default level is **notice**)
77 Affects driver-wide messages unrelated to any particular devices.
79 - ``pmd.net.txgbe.init`` (default level is **notice**)
81 Extra logging of the messages during PMD initialization.
