For the userspace tracing at minium following libraries are required.

It would be well worth considering one of the vpp techniques to minimize trace
impact:
static inline ring_handler_inline (..., int is_traced)
{
for (i = 0; i < vector_size; i++)
{
if (is_traced)
{
do_trace_work;
}
normal_packet_processing;
}
}

Hi All,
I would like to add tracing support for DPDK.
I am planning to add this support in v20.05 release.
This RFC attempts to get feedback from the community on
a) Tracing Use cases.
b) Tracing Requirements.
b) Implementation choices.
c) Trace format.
Use-cases
-
- Most of the cases,
Hi Jerin,
Any idea why lttng performance is so poor?
I would have naturally gone there to benefit from the existing toolchain.
Have you looked at the FD.io logging/tracing infrastructure for inspiration?
