[PATCH v2 00/11] drm: kunit: Switch to kunit actions

by Maxime Ripard

Hi, Since v6.5-rc1, kunit gained a devm/drmm-like mechanism that makes tests resources much easier to cleanup. This series converts the existing tests to use those new actions where relevant. Let me know what you think, Maxime Signed-off-by: Maxime Ripard <mripard(a)kernel.org> --- Changes in v2: - Fix some typos - Use plaltform_device_del instead of removing the call to platform_device_put after calling platform_device_add - Link to v1: https://lore.kernel.org/r/20230710-kms-kunit-actions-rework-v1-0-722c58d72c… --- Maxime Ripard (11): drm/tests: helpers: Switch to kunit actions drm/tests: client-modeset: Remove call to drm_kunit_helper_free_device() drm/tests: modes: Remove call to drm_kunit_helper_free_device() drm/tests: probe-helper: Remove call to drm_kunit_helper_free_device() drm/tests: helpers: Create a helper to allocate a locking ctx drm/tests: helpers: Create a helper to allocate an atomic state drm/vc4: tests: pv-muxing: Remove call to drm_kunit_helper_free_device() drm/vc4: tests: mock: Use a kunit action to unregister DRM device drm/vc4: tests: pv-muxing: Switch to managed locking init drm/vc4: tests: Switch to atomic state allocation helper drm/vc4: tests: pv-muxing: Document test scenario drivers/gpu/drm/tests/drm_client_modeset_test.c | 8 -- drivers/gpu/drm/tests/drm_kunit_helpers.c | 108 +++++++++++++++++++++- drivers/gpu/drm/tests/drm_modes_test.c | 8 -- drivers/gpu/drm/tests/drm_probe_helper_test.c | 8 -- drivers/gpu/drm/vc4/tests/vc4_mock.c | 5 ++ drivers/gpu/drm/vc4/tests/vc4_test_pv_muxing.c | 115 +++++++++--------------- include/drm/drm_kunit_helpers.h | 7 ++ 7 files changed, 158 insertions(+), 101 deletions(-) --- base-commit: c58c49dd89324b18a812762a2bfa5a0458e4f252 change-id: 20230710-kms-kunit-actions-rework-5d163762c93b Best regards, -- Maxime Ripard <mripard(a)kernel.org>

[PATCH v2 0/3] kunit: Expose some built-in features to modules

by Janusz Krzysztofik

Submit the top-level headers also from the kunit test module notifier initialization callback, so external tools that are parsing dmesg for kunit test output are able to tell how many test suites should be expected and whether to continue parsing after complete output from the first test suite is collected. Extend kunit module notifier initialization callback with a processing path for only listing the tests provided by a module if the kunit action parameter is set to "list", so external tools can obtain a list of test cases to be executed in advance and can make a better job on assigning kernel messages interleaved with kunit output to specific tests. Use test filtering functions in kunit module notifier callback functions, so external tools are able to execute individual test cases from kunit test modules in order to still better isolate their potential impact on kernel messages that appear interleaved with output from other tests. v2: Fix new name of a structure moved to kunit namespace not updated across all uses.

[PATCH v3 0/7] tools/nolibc: add 32/64-bit powerpc support

Hi, Willy, Thomas v3 here is to fix up two issues introduced in v2 powerpc patchset [1]. - One is restore the wrongly removed '\' for a '\$$ARCH' - Another is add the missing $(ARCH).config for ppc, the default variant for powerpc is renamed to ppc in v2 (as discussed with Willy in [2]), but ppc.config is missing in v2 patchset, not sure why this happen, may a 'git clean -fdx .' is required to do a new test, just did it. Btw, the v3 tinyconfig-part1 for powerpc is ready, I will send it out soon.

Re: [PATCH v5] selftests: rtc: Improve rtctest error handling

by Greg KH

Hi, This is the semi-friendly patch-bot of Greg Kroah-Hartman. Markus, you seem to have sent a nonsensical or otherwise pointless review comment to a patch submission on a Linux kernel developer mailing list. I strongly suggest that you not do this anymore. Please do not bother developers who are actively working to produce patches and features with comments that, in the end, are a waste of time. Patch submitter, please ignore Markus's suggestion; you do not need to follow it at all. The person/bot/AI that sent it is being ignored by almost all Linux kernel maintainers for having a persistent pattern of behavior of producing distracting and pointless commentary, and inability to adapt to feedback. Please feel free to also ignore emails from them. thanks, greg k-h's patch email bot

damos_new_filter() is returning a damos_filter struct without initializing its ->list field. And the users of the function uses the struct without initializing the field.

[PATCH v2 00/14] selftests/nolibc: add minimal kernel config support - part1

by Zhangjin Wu

Hi, Willy, Thomas Here is the first part of v2 of our tinyconfig support for nolibc-test [1], the patchset subject is reserved as before. As discussed in v1 thread [1], to easier the review progress, the whole tinyconfig support is divided into several parts, mainly by architecture, here is the first part, include basic preparation and powerpc example. This patchset should be applied after the 32/64-bit powerpc support [2], exactly these two are required by us: * selftests/nolibc: add extra config file customize support * selftests/nolibc: add XARCH and ARCH mapping support In this patchset, we firstly add some misc preparations and at last add the tinyconfig target and use powerpc as the first example. Tests: // powerpc run-user $ for arch in powerpc powerpc64 powerpc64le; do \ rm -rf $PWD/kernel-$arch; \ mkdir -p $PWD/kernel-$arch; \ make run-user XARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out | grep "status: "; \ done 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning // powerpc run $ for arch in powerpc powerpc64 powerpc64le; do \ rm -rf $PWD/kernel-$arch; \ mkdir -p $PWD/kernel-$arch; \ make tinyconfig run XARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out; \ done $ for arch in powerpc powerpc64 powerpc64le; do \ make report XARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out | grep "status: "; \ done 165 test(s): 156 passed, 9 skipped, 0 failed => status: warning 165 test(s): 156 passed, 9 skipped, 0 failed => status: warning 165 test(s): 156 passed, 9 skipped, 0 failed => status: warning // the others, randomly choose some $ make run-user XARCH=arm O=$PWD/kernel-arm RUN_OUT=$PWD/run.arm.out CROSS_COMPILE=arm-linux-gnueabi- | grep status: 165 test(s): 156 passed, 9 skipped, 0 failed => status: warning $ make run-user XARCH=x86_64 O=$PWD/kernel-arm RUN_OUT=$PWD/run.x86_64.out CROSS_COMPILE=x86_64-linux-gnu- | grep status: 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning $ make run-libc-test | grep status: 165 test(s): 153 passed, 12 skipped, 0 failed => status: warning // x86_64, require noapic kernel command line option for old qemu-system-x86_64 (v4.2.1) $ make run XARCH=x86_64 O=$PWD/kernel-x86_64 RUN_OUT=$PWD/run.x86_64.out CROSS_COMPILE=x86_64-linux-gnu- | grep status $ make rerun XARCH=x86_64 O=$PWD/kernel-x86_64 RUN_OUT=$PWD/run.x86_64.out CROSS_COMPILE=x86_64-linux-gnu- | grep status 165 test(s): 159 passed, 6 skipped, 0 failed => status: warning tinyconfig mainly targets as a time-saver, the misc preparations service for the same goal, let's take a look: * selftests/nolibc: allow report with existing test log Like rerun without rebuild, Add report (without rerun) to summarize the existing test log, this may work perfectly with the 'grep status' * selftests/nolibc: add macros to enhance maintainability Several macros are added to dedup the shared code to shrink lines and easier the maintainability The macros are added just before the using area to avoid code change conflicts in the future. * selftests/nolibc: print running log to screen Enable logging to let developers learn what is happening at the first glance, without the need to edit the Makefile and rerun it. These helps a lot when there is a long-time running, a failed poweroff or even a forever hang. For test summmary, the 'grep status' can be used together with the standalone report target. * selftests/nolibc: fix up O= option support With objtree instead srctree for .config and IMAGE, now, O= works. Using O=$PWD/kernel-$arch avoid the mrproer for every build. * selftests/nolibc: add menuconfig for development Allow manually tuning some options, mainly for a new architecture porting. * selftests/nolibc: add mrproper for development selftests/nolibc: defconfig: remove mrproper target Split the mrproper target out of defconfig, when with O=, mrproper is not required by defconfig, but reserve it for the other use scenes. * selftests/nolibc: string the core targets Allow simply 'make run' instead of 'make defconfig; make extconfig; make kernel; make run'. * selftests/nolibc: allow quit qemu-system when poweroff fails When poweroff fails, allow exit while detects the power off string from output or the wait time is too long (specified by QEMU_TIMEOUT). This helps the boards who have no poweroff support or the kernel not enable the poweroff options (mainly for tinyconfig). * selftests/nolibc: allow customize CROSS_COMPILE by architecture * selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc This further saves a CROSS_COMPILE option for 'make run', it is very important when iterates all of the supported architectures and the compilers are not just prefixed with the XARCH variable. For example, binary of big endian powerpc64 can be compiled with powerpc64le-linux-gnu-, but the prefix is powerpc64le. Even if the pre-customized compiler not exist, we can configure CROSS_COMPILE_<ARCH> before the test loop to use the code. * selftests/nolibc: add tinyconfig target selftests/nolibc: tinyconfig: add extra common options selftests/nolibc: tinyconfig: add support for 32/64-bit powerpc Here is the first architecture(and its variants) support tinyconfig. powerpc is actually a very good architecture, for it has 'various' variants for test.

[PATCH 0/3] kunit: Expose some built-in features to modules

by Janusz Krzysztofik

Submit the top-level headers also from the kunit test module notifier initialization callback, so external tools that are parsing dmesg for kunit test output are able to tell how many test suites should be expected and whether to continue parsing after complete output from the first test suite is collected. Extend kunit module notifier initialization callback with a processing path for only listing the tests provided by a module if the kunit action parameter is set to "list", so external tools can obtain a list of test cases to be executed in advance and can make a better job on assigning kernel messages interleaved with kunit output to specific tests. Use test filtering functions in kunit module notifier callback functions, so external tools are able to execute individual test cases from kunit test modules in order to still better isolate their potential impact on kernel messages that appear interleaved with output from other tests.
