Integrate the selftests as part of kunit.
Now instead of the test only being run at boot, it can run:
- With CONFIG_IOMMU_IO_PGTABLE_LPAE_KUNIT_TEST=y
It will automatically run at boot as before.
- Otherwise with CONFIG_IOMMU_IO_PGTABLE_LPAE_KUNIT_TEST=m:
1) on module load:
Once the module load the self test will run
# modprobe io-pgtable-arm-selftests
2) debugfs
With CONFIG_KUNIT_DEBUGFS=y You can run the test with
# echo 1 > /sys/kernel/debug/kunit/io-pgtable-arm-test/run
3) Using kunit.py
You can also use the helper script which uses Qemu in the background
# ./tools/testing/kunit/kunit.py run --build_dir build_kunit_arm64 --arch arm64 \
--make_options LLVM=1 --kunitconfig ./kunit/kunitconfig
