For built-in tests, the kunit_test_suite{,s}() macro adds a list of suites in the .kunit_test_suites linker section. However, for kernel modules, a module_init() function is used to run the test suites. This causes problems if tests are included in a module which already defines module_init/exit_module functions, as they'll conflict with the kunit-provided ones. This change removes the kunit-defined module inits, and instead parses the kunit tests from their own section in the module. After module init, we call __kunit_test_suites_init() on the contents of that section, which prepares and runs the suite. This essentially unifies the module- and non-module kunit init formats.

For every test file, we store a struct kunit_suite** NULL-terminated array. This adds quite a bit of complexity to the test filtering code in the executor. Instead, let's just make the .kunit_test_suites section contain a single giant array of struct kunit_suite pointers, which can then be directly manipulated. This array is not NULL-terminated, and so none of the test filtering code needs to NULL-terminate anything.

Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is enabled. This means that kunit_tool can now successfully run and parse the test results with, for example: ./tools/testing/kunit/kunit.py run --arch=x86_64 \ --kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \ 'thunderbolt' Acked-by: Mika Westerberg Acked-by: Daniel Latypov Signed-off-by: David Gow Acked-by: Brendan Higgins --- Changes since v2: https://lore.kernel.org/linux-kselftest/20220621085345.603820-4-davidgow@google.com/ - Don't permit USB4_KUNIT_TESTS to be enabled when USB4=y and KUNIT=m i.e., add a dependency on (USB4=m || KUNIT=y) This would result in undefined kunit symbols being used, otherwise. - Add Daniel's Acked-by Changes since v1: https://lore.kernel.org/linux-kselftest/20220618090310.1174932-4-davidgow@google.com/ - Actually include the Kconfig changes, which were mistakenly added to the next patch in the series in v1. - Add Acked-by tag from Mika Westerberg --- drivers/thunderbolt/Kconfig | 6 ++++-- drivers/thunderbolt/domain.c | 3 --- drivers/thunderbolt/tb.h | 8 -------- drivers/thunderbolt/test.c | 12 +----------- 4 files changed, 5 insertions(+), 24 deletions(-) diff --git a/drivers/thunderbolt/Kconfig b/drivers/thunderbolt/Kconfig index 4bfec8a28064..e76a6c173637 100644 --- a/drivers/thunderbolt/Kconfig +++ b/drivers/thunderbolt/Kconfig @@ -28,8 +28,10 @@ config USB4_DEBUGFS_WRITE this for production systems or distro kernels. config USB4_KUNIT_TEST - bool "KUnit tests" - depends on KUNIT=y + bool "KUnit tests" if !KUNIT_ALL_TESTS + depends on (USB4=m || KUNIT=y) + depends on KUNIT + default KUNIT_ALL_TESTS config USB4_DMA_TEST tristate "DMA traffic test driver" diff --git a/drivers/thunderbolt/domain.c b/drivers/thunderbolt/domain.c index 2889a214dadc..99211f35a5cd 100644 --- a/drivers/thunderbolt/domain.c +++ b/drivers/thunderbolt/domain.c @@ -872,7 +872,6 @@ int tb_domain_init(void) { int ret;

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.)
