Just tested it, and it didn't have the wanted effect.
I think rte_trace_is_enabled() returns false until at least one tracepoint has been enabled, which seems like a good optimization.
But it also means that we cannot use it to replace __rte_trace_point_generic_is_enabled() in test/app, because no tracepoints have been enabled at this point of execution, so it returns false here.
I looked around in the code, and cannot find a method without looking at internals, or duplicating a test case.
I could test if rte_trace_point_lookup("app.dpdk.test.tp") returns non-NULL, but that would duplicate the same test in test_trace_points_lookup().
What do you think...
Keep using internal function __rte_trace_point_generic_is_enabled(),
test rte_trace_point_lookup("app.dpdk.test.tp") != NULL,
or any other idea?
