35 Pre-Installation Configuration
36 ------------------------------
41 The following build-time options may be enabled on build time using.
43 ``-Dc_args=`` meson argument (e.g. ``-Dc_args=-DRTE_LIBRTE_TXGBE_DEBUG_RX``).
45 Please note that enabling debugging options may affect system performance.
47 - ``RTE_LIBRTE_TXGBE_DEBUG_RX`` (undefined by default)
49 Toggle display of receive fast path run-time messages.
51 - ``RTE_LIBRTE_TXGBE_DEBUG_TX`` (undefined by default)
53 Toggle display of transmit fast path run-time messages.
55 - ``RTE_LIBRTE_TXGBE_DEBUG_TX_FREE`` (undefined by default)
57 Toggle display of transmit descriptor clean messages.
59 Dynamic Logging Parameters
60 ~~~~~~~~~~~~~~~~~~~~~~~~~~
62 One may leverage EAL option "--log-level" to change default levels
63 for the log types supported by the driver. The option is used with
64 an argument typically consisting of two parts separated by a colon.
66 TXGBE PMD provides the following log types available for control:
68 - ``pmd.net.txgbe.driver`` (default level is **notice**)
70 Affects driver-wide messages unrelated to any particular devices.
72 - ``pmd.net.txgbe.init`` (default level is **notice**)
74 Extra logging of the messages during PMD initialization.
76 Driver compilation and testing
