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 <[email protected]> Signed-off-by: Longpeng <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
