      Userspace utilities for the LTTng 2.x tracing

      infrastructure.

​

      Those utilities are required on the target system to start

      and stop tracing sessions. Analysis of the trace can be done

      on the host machine using the babeltrace utility. This

      utility is automatically built by Buildroot in

      $(O)/host/usr/bin/babeltrace, as a dependency of

      lttng-tools. However, there is also a lttng-babeltrace

      package for the target, if babeltrace on the target is

      interesting.

​

      If userspace tracing is desired, you need to enable

      lttng-libust.
