The new implementation of kunit_test_suite() for modules no longer conflicts with module_init, so can now be used by the thunderbolt tests. 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 <mika.westerberg@xxxxxxxxxxxxxxx> Acked-by: Daniel Latypov <dlatypov@xxxxxxxxxx> Acked-by: Brendan Higgins <brendanhiggins@xxxxxxxxxx> Signed-off-by: David Gow <davidgow@xxxxxxxxxx> --- Changes since v3: https://lore.kernel.org/linux-kselftest/20220625050838.1618469-4-davidgow@xxxxxxxxxx/ - Rebase on top of the TAINT_TEST patch series. This should now apply cleanly on top of the kunit branch: https://lore.kernel.org/linux-kselftest/20220708044847.531566-1-davidgow@xxxxxxxxxx/T/#u - Add Brendan's Acked-by tag. Changes since v2: https://lore.kernel.org/linux-kselftest/20220621085345.603820-4-davidgow@xxxxxxxxxx/ - 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@xxxxxxxxxx/ - 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; - tb_test_init(); tb_debugfs_init(); tb_acpi_init(); @@ -890,7 +889,6 @@ int tb_domain_init(void) err_acpi: tb_acpi_exit(); tb_debugfs_exit(); - tb_test_exit(); return ret; } @@ -903,5 +901,4 @@ void tb_domain_exit(void) tb_xdomain_exit(); tb_acpi_exit(); tb_debugfs_exit(); - tb_test_exit(); } diff --git a/drivers/thunderbolt/tb.h b/drivers/thunderbolt/tb.h index 4602c69913fa..a831faa50f65 100644 --- a/drivers/thunderbolt/tb.h +++ b/drivers/thunderbolt/tb.h @@ -1271,12 +1271,4 @@ static inline void tb_service_debugfs_init(struct tb_service *svc) { } static inline void tb_service_debugfs_remove(struct tb_service *svc) { } #endif -#ifdef CONFIG_USB4_KUNIT_TEST -int tb_test_init(void); -void tb_test_exit(void); -#else -static inline int tb_test_init(void) { return 0; } -static inline void tb_test_exit(void) { } -#endif - #endif diff --git a/drivers/thunderbolt/test.c b/drivers/thunderbolt/test.c index ee37f8b58f50..24c06e7354cd 100644 --- a/drivers/thunderbolt/test.c +++ b/drivers/thunderbolt/test.c @@ -2817,14 +2817,4 @@ static struct kunit_suite tb_test_suite = { .test_cases = tb_test_cases, }; -static struct kunit_suite *tb_test_suites[] = { &tb_test_suite, NULL }; - -int tb_test_init(void) -{ - return __kunit_test_suites_init(tb_test_suites); -} - -void tb_test_exit(void) -{ - return __kunit_test_suites_exit(tb_test_suites); -} +kunit_test_suite(tb_test_suite); -- 2.37.0.rc0.161.g10f37bed90-goog
