[PATCH RFC] drm/i915: allow running mock selftests via Kunit

Tue Nov 1 16:42:26 UTC 2022
The mock selftests don't require any hardware to run. They can
easily run via kunit with qemu or bare metal.
Add support for it.
With this change, mock selftest can now run in qemu with:
$ ./tools/testing/kunit/kunit.py run --arch=x86_64 \
--kunitconfig=drivers/gpu/drm/i915/selftests

It is also possible to run the tests on a bare metal machine,
and even collect code coverage data with:
$ sudo lcov -z && sudo modprobe test-i915 && sudo rmmod test-i915 &&
sudo IGT_KERNEL_TREE=~/linux ~/freedesktop-igt/scripts/code_cov_capture mock_selftest
Auto-detecting gcov kernel support.
Found upstream gcov kernel support at /sys/kernel/debug/gcov
Resetting kernel execution counters
Done.

The KTAP and Kernel logs will be similar to:

Note: kunit.py is currently broken with modules, not producing any
results if "TAP version xx" is not found. It also shows the results
duplicated.
