There are several tests which depend on PCI, and hence need a bunch of
extra options to run under UML. This makes it awkward to give
configuration instructions (whether in documentation, or as part of a
.kunitconfig file), as two separate, incompatible sets of config options
are required for UML and "most other architectures".
For non-UML architectures, it's possible to add default kconfig options
via the qemu_config python files, but there's no equivalent for UML. Add
a new tools/testing/kunit/configs/arch_uml.config file containing extra
kconfig options to use on UML.

Changes since RFC:
https://lore.kernel.org/linux-kselftest/[email protected]/
- Rebase on top of the previous kconfig patches.
- Fix a missing make_arch_qemuconfig->make_arch_config rename (Thanks
Brendan)
- Fix the tests to use the base LinuxSourceTreeOperations class, which
has no default kconfig options (and so won't conflict with those set
in the tests). Only test_build_reconfig_existing_config actually
failed, but I updated a few more in case the defaults changed.

After applying this patch and its dependencies, I can confirm that it is
possible to run the DRM tests with the following command:
$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/tests
Added a TODO for myself to remove the extra flag from the DRM docs once
this patch is merged.
Thanks a lot for making it easier!

This runs and typechecks under mypy, but not under pytype.
The problem is that the first argument is type str, not Optional[str].
I think a fix would be to just use LinuxSourceTreeOperationsUml() instead here.
Since you recently switched machines, you might want to run:
$ pip install pytype
And then
$ ./tools/testing/kunit/run_checks.py
would run pytype and show you the complaints here.

Oh, I see what you're doing here, we want to avoid the new step where
UML now adds to the .kunitconfig file.
Something like this could work
- tree._ops = kunit_kernel.LinuxSourceTreeOperations(None, None)
+ tree._ops = kunit_kernel.LinuxSourceTreeOperations('none', None)
or we could put 'fake', etc.
If we're not happy with using this class directly (since it's meant to
subclassed), an alternative, more targeted approach could be:
mock.patch.object(tree._ops, 'make_arch_config', lambda x: x).start()
But I don't like this and would prefer the above.
