45.3. Configuration

45.3.1. 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.

NGBE PMD provides the following log types available for control:

• pmd.net.ngbe.driver (default level is notice)

  Affects driver-wide messages unrelated to any particular devices.

• pmd.net.ngbe.init (default level is notice)

  Extra logging of the messages during PMD initialization.

45.4. Driver compilation and testing

Refer to the document compiling and testing a PMD for a NIC for details.

45.5. Limitations or Known issues

Build with ICC is not supported yet. Power8, ARMv7 and BSD are not supported yet.
