nitro_enclaves: test: Use kunit_test_suite() macro

2022-07-11T23:13:27+00:00

The kunit_test_suite() macro previously conflicted with module_init, making it unsuitable for use in the nitro_enclaves test. Now that it's fixed, we can use it instead of a custom call into internal KUnit functions to run the test. As a side-effect, this means that the test results are properly included with other suites when built-in. To celebrate, enable the test by default when KUNIT_ALL_TESTS is set (and NITRO_ENCLAVES enabled). The nitro_enclave tests can now be run via kunit_tool with: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_SMP=y \ --kconfig_add CONFIG_HOTPLUG_CPU=y \ --kconfig_add CONFIG_VIRT_DRIVERS=y \ --kconfig_add CONFIG_NITRO_ENCLAVES=y \ 'ne_misc_dev_test' (This is a pretty long command, so it may be worth adding a .kunitconfig file at some point, instead.)

nitro_enclaves: Add KUnit tests for contiguous physical memory regions merging

2021-11-17T15:11:09+00:00

Add KUnit tests for the contiguous physical memory regions merging functionality from the Nitro Enclaves misc device logic. We can build the test binary with the following configuration: CONFIG_KUNIT=y CONFIG_NITRO_ENCLAVES=m CONFIG_NITRO_ENCLAVES_MISC_DEV_TEST=y and install the nitro_enclaves module to run the testcases. We'll see the following message using dmesg if everything goes well: [...] # Subtest: ne_misc_dev_test [...] 1..1 [...] (NULL device *): Physical mem region address is not 2 MiB aligned [...] (NULL device *): Physical mem region size is not multiple of 2 MiB [...] (NULL device *): Physical mem region address is not 2 MiB aligned [...] ok 1 - ne_misc_dev_test_merge_phys_contig_memory_regions [...] ok 1 - ne_misc_dev_test Reviewed-by: Andra Paraschiv Signed-off-by: Longpeng Link: https://lore.kernel.org/r/20211107140918.2106-5-longpeng2@huawei.com Signed-off-by: Greg Kroah-Hartman
