[PATCH] Add recipe for linux kselftest

[Vijai Kumar K]

Kselftest is a set of unit and regression tests under the
tools/testing/selftests/ directory of the Linux kernel. These are used
for testing individual code paths in the kernel.

Kselftest is not debianized and is not available as part of the official
Debian repository.

This patch provides a recipe to build kselftest from the linux source of
your choice.

Sometimes developers/testers tend to use the latest version of selftests
from Linux upstream stable releases for testing and hence the need for a
separate recipe instead of being part of the linux recipe of ISAR.

Some kselftest test cases build are known to break in certain linux
versions, this has to be addressed upstream. Right now kselftest build
succeeds even if atleast one of the testcase case build succeeds.

You can change that by setting KSELFTEST_FORCE_TARGETS=1.

TARGETS, TARGETS_SKIP, FORCE_TARETS can be set using the appropriate
KSELFTEST_* recipe variable.

Are all of these deps specific to the version, or would it make sense to
extract some common ones (or even all?) to kselftest.inc?

The SRC_URI and S are likely also version-independent.

This looks to like deb_create_control could generate it as well. If you
like, you could still patch the setion afterward from misc to kernel.

Why that? Please leave a comment so that it can be revisited in future
releases, or make version dependent (-> move to .bb recipe).

On the limited versions of Linux I have tested, this seems common when
you build ALL
test cases. This list is a collection of dependencies needed by ALL
the testcases(TARGETS)
that kselftest builds.

We could also specify the limited list of test cases you want to
compile using "TARGETS=" & "SKIP_TARGETS="
variables.

If you just compiling for say "size" test case you may not need any
of these. That is the
reason I had these depends in the bb. The common ones like bison, flex
and rsync are there kselftest.inc

Sorry, but I am not getting this. Can you please elaborate?

I will have a look into that API. Will address in v2.

Will have a look and possibly address in v2.

I remember having issues with some test cases failing in cross
compilation. Added this to make sure the deb has
consistent working testcases in ISAR cross compilation setup. I have
to look back at my notes on what failed.
Will have a look and take care of this in v2.

If you can identify some dependency clusters for specific test case set,
adding them automatically when selecting a set would be nice. Otherwise,
I would simply go for "add them all". Background is that only little
information should be left in the example & test layer meta-isar.

Move them to kselftest.inc. Reduces the boilerplate one has to add to an
own recipe.

Perfect.

Thanks, this is a useful addition.

I'd suggest to address Jan's point and replace the individual commands with
deb_debianize to provide a good in-tree example of using that functionality.

To prevent bit rot, I think every component in the mainline should have a test
case. We could add the package to e.g. isar-image-debug and build e.g.
mc:qemuamd64-buster:isar-image-debug instead of
mc:qemuamd64-buster:isar-image-base.

What do you think?

With kind regards,
Baurzhan.

Sure. We could use deb_debianize. Will address in v3.

Looks good to me. Will address it in v3.
