Hi, Here's a series that sets the speed attribute to slow on DRM tests that are taking a while to execute. With those patches, an initial run of the drm tests on arm64 were taking 59s to execute with: $ ./tools/testing/kunit/kunit.py run \ --kunitconfig=drivers/gpu/drm/tests \ --arch arm64 \ --cross_compile aarch64-linux-gnu- ... [11:50:07] Testing complete. Ran 340 tests: passed: 340 [11:50:07] Elapsed time: 62.261s total, 0.001s configuring, 2.703s building, 59.532s running and are now taking 1.7s when filtering out the slow tests: $ ./tools/testing/kunit/kunit.py run \ --kunitconfig=drivers/gpu/drm/tests \ --arch arm64 \ --cross_compile aarch64-linux-gnu- \ --filter "speed>slow" ... [11:47:52] Testing complete. Ran 332 tests: passed: 332 [11:47:52] Elapsed time: 6.449s total, 0.001s configuring, 4.728s building, 1.678s running Let me know what you think, Maxime Signed-off-by: Maxime Ripard <mripard@xxxxxxxxxx> --- Maxime Ripard (2): kunit: Warn if tests are slow drm/tests: Flag slow tests as such drivers/gpu/drm/tests/drm_buddy_test.c | 2 +- drivers/gpu/drm/tests/drm_mm_test.c | 14 +++++++------- lib/kunit/test.c | 16 ++++++++++++++++ 3 files changed, 24 insertions(+), 8 deletions(-) --- base-commit: 0bb80ecc33a8fb5a682236443c1e740d5c917d1d change-id: 20230911-kms-slow-tests-0261bee9a54b Best regards, -- Maxime Ripard <mripard@xxxxxxxxxx>
