[PATCH] examples/pipeline: fix include path for rte_log.h

[Cristian Dumitrescu]

When rte_log.h was moved to a new directory, the include path was not
updated for the generated C code produced by the pipeline library,
which results in build failure for this code.

Wrt $Subject, copy/paste code in drivers/net/softnic is broken too.

Some comments on this code:
- putting compilation commands seems a rather strange idea in C code,
but at least, why not invoke an external tool/script that makes use of
existing build framework?
- RTE_INSTALL_DIR is undocumented,
- this implementation (passing -I <some_directory>/lib/eal/include) is
broken with a system-installed dpdk,

You're right, let me fix this in V2.

Yes, I am thinking of transitioning the pipeline app from the examples
folder to the apps folder, as it is way more than an example at this point,
and also add a script/tool to generate the C code in a more configurable
way. For now, the examples/pipeline contains just the default way to do
this, but of course a standalone tool would be better. On my ToDo list.
Thanks for providing this input!

> - RTE_INSTALL_DIR is undocumented,

This option is not supposed to be broadly used, but it is there just in case.
When the tool mentioned above will be ready, this will be moved into that
tool.

Yes, this is expected. For the purpose of the pipeline C code generation,
we need the path to the full DPDK folder, not just the public header files.
There is one internal DPDK internal header file (rte_pipeline_internal.h)
which is needed for code generation purposes, but it should not be
made a public header, as it does not contain the pipeline API that apps
are using.

Hi Cristian,

How can I verify the fix? Can you please list the required steps?


And I wonder how this skipped the testing, I guess v23.11 released with
this defect. Is there a gap in the CI or internal build/test scripts?

I guess maybe (?) with the pipeline DTS case, but I'm not sure that
would be sufficient.

I don't know that softnic driver is used in the lab.  Actually, would
DTS suite even have triggered this issue?  I'm not sure if there is a
set of tests which covers the case.  Maybe Patrick can confirm about the
pipeline test?

So, based on what Cristian stated (passing in any of the .cli files when
starting the pipeline example app would show it is fixed), yes I assume the
DTS testsuite would have caught this, as I can see the testsuite does do
that. But, yes it's also true that the pipeline testsuites are not run at
UNH or the Intel Lab (the two labs which publicly report DTS results), so
that's how this gets through CI Testing. It is not possible (testing
capacity wise) to run every testsuite, and I don't think there has been
conversation between the lab and our vendor contacts about this specific
coverage (at least not while I've been working here).

However, based on the physical testplan requirements (4 10G tester ports to
4 10G DUT ports), we could bring the testsuite online if there is
interest(and the testsuite hasn't broken since it dropped in 2020). One of
our Intel testbeds which we run currently has exactly that NIC topology,
and it also doesn't have bad testing capacity concerns as compared to some
other testbeds. Let me know if there is an interest in this coverage and
I'll make a ticket for the team to take a look. At a minimum we could dry
run the framework on the testbed I'm thinking of and provide feedback,
which I suppose would take only a couple minutes/hours. Christian let me
know if that's a value - it's a low barrier of entry to dry run.

[Cristian]
Yes, you are right, we do have a DTS test suite for the pipeline library.

It would be great to run it automatically as part of the CI testing. Just a word of caution though: I am not the owner of those tests, and also not intimately familiar with them, so it might be hard to find volunteers to setup the test suite, that the only problem that I see unfortunately. But we should try and see if there are any issues at all.

Thanks,
Cristian

Okay, the setup doesn't look too burdensome anyhow so we should be alright
with just the team here at UNH. I'll let you know how it goes.

Just build the examples/pipeline app and the run this app with the command line below (you can use l2fwd.cli or any other .cli file from the same folder):
	./build/examples/dpdk-pipeline -l0-1 -- -s ./examples/pipeline/examples/l2fwd.cli

If everything works, then you should:
	i) not get any error message, especially for the "pipeline libbuild /tmp/l2fwd.c /tmp/l2fwd.so" line from l2fwd.cli script).
	ii) have the file "/tmp/l2fwd.so" created.
	iii) get the traffic flowing (if you have the NICs working)

Note: you would need to adjust the ethdev BFDs to those in your setup in the .cli file and the ethdev.io file from the same folder. Just read through the .cli file.

Ping me if you get into trouble.

Thanks, I just tested the /tmp/l2fwd.so build, and confirmed the fix.

But it is hard to script this testcase. If 'dpdk-pipeline' exits with
failure when building ' /tmp/l2fwd.so' fails, at least this can be
tested easier in a script, does this make sense?

Patch has both net/softnic and examples/pipeline update, since update is
trivial and for exact same issue, instead of requesting a patch split I
am getting it directly to next-net to not create more overhead.

Applied to dpdk-next-net/main, thanks.
