Merge tag 'trace-tools-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-tracePull RTLA tool updates from Steven Rostedt: - Fix discrepancy in --dump-tasks option Due to a mistake, rtla-timerlat-hist used the CLI syntax "--dump-task" instead of the documented "--dump-tasks". Change the option to match both documentation and the other timerlat tool, rtla-timerlat-top. - Extend coverage of runtime tests Cover both top and hist tools in all applicable test cases, add tests for a few uncovered options, and extend checks for some existing tests. - Add unit tests for actions rtla's actions feature is implemented in its source file and contains non-trivial parsing logic. Cover it with unit tests. - Stop record trace on interrupt Fix a bug where an interval exists after receiving a signal in which the main instance is stopped but the record instance is not, leading to discrepancies in reported results and sometimes rtla hanging. - Restore continue flag in actions_perform() Fix a bug where rtla always continues tracing after hitting a threshold even if the continue action was triggered just once, and add tests verifying that the flag is reset properly. - Migrate command line interface to libsubcmd Replace rtla's argument parsing using getopt_long() with libsubcmd, used by perf and objtool, to reuse existing code and auto-generate better help messages. Extensive unit tests are included to detect regressions. - Add -A/--aligned option to timerlat tools Add an option to align timerlat threads, based on the recently introduced TIMERLAT_ALIGN option of the timerlat tracer, together with unit tests and documentation. - Document tests in README Document how to run unit and runtime tests in rtla's README.txt, including the dependencies needed to run them.* tag 'trace-tools-v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (26 commits) rtla: Document tests in README Documentation/rtla: Add -A/--aligned option rtla/tests: Add unit tests for -A/--aligned option rtla/timerlat: Add -A/--aligned CLI option rtla/tests: Add unit tests for CLI option callbacks rtla/tests: Add unit tests for _parse_args() functions rtla: Parse cmdline using libsubcmd tools subcmd: allow parsing distinct --opt and --no-opt tools subcmd: support optarg as separate argument rtla: Add libsubcmd dependency rtla/tests: Add runtime tests for restoring continue flag rtla/tests: Run runtime tests in temporary directory rtla/tests: Add unit test for restoring continue flag rtla/actions: Restore continue flag in actions_perform() rtla: Stop the record trace on interrupt rtla/tests: Add unit tests for actions module rtla/tests: Add runtime tests for -C/--cgroup rtla/tests: Add runtime test for -k and -u options rtla/tests: Add runtime test for -H/--house-keeping rtla/tests: Cover all hist options in runtime tests ...

596a9bed0aec60490dffd85bd1865430ce298eba - rtla/tests: Add unit tests for CLI option callbacks

Thu, 28 May 2026 12:32:54 +0200

rtla/tests: Add unit tests for CLI option callbacksIn addition to testing all tool_parse_args() functions, test also allcallbacks used for parsing custom option formats.The callbacks represent a middle layer between the parsing functionsand utility functions dedicated to checking specific argument formats,for example, scheduling class and duration. Callback tests are runbefore parsing functions to make sure any issue in the former isreported before it is encountered through the latter.Tests verify both successful parsing and proper rejection of invalidinputs (via exit tests). To enable testing static callbacks, a pragmaonce guard is added to timerlat.h for safe inclusion by cli_p.h.Add dependency of UNIT_TESTS_IN on LIBSUBCMD_INCLUDES, as the new testfile tests/unit/cli_opt_callback.c includes cli_p.h which includessubcmd/parse-options.h.Link: https://lore.kernel.org/r/20260528103254.2990068-7-tglozar@redhat.comSigned-off-by: Tomas Glozar List of files: /linux/tools/tracing/rtla/tests/unit/Build

244d0cbff2efa13931115784e5dc4d1270a04ec7 - rtla/tests: Add unit tests for _parse_args() functions

Thu, 28 May 2026 12:32:53 +0200

rtla/tests: Add unit tests for _parse_args() functionsAdd a test suite for the _parse_args() function of each tool that checksthe params structures (struct common_params, struct osnoise_params,struct timerlat_params) returned by them for correctness.One test case is added per option, as well as a few special cases fortricky combinations of options. Test cases are ordered the same as theoption arrays and help message to allow easy checking of whether alloptions are covered.This should help clarify what the proper command line behavior of RTLAis in case there are holes in the documentation and verify that theintended behavior is implemented correctly.A few necessary changes to the unit tests were done as part of thiscommit:- Unit tests now also link to libsubcmd and its dependencies.- A new global variable in_unit_test is added to RTLA's CLI interface, causing it to skip check for root if running in unit tests. This allows the CLI unit tests to run as non-root, like existing unit tests.There is quite a lot of duplication, some of it is mitigated with macros,but partially it is intentional so that future changes in behavior aretracked across tools.Link: https://lore.kernel.org/r/20260528103254.2990068-6-tglozar@redhat.comSigned-off-by: Tomas Glozar List of files: /linux/tools/tracing/rtla/tests/unit/Build

e5d8f22758c5904ed006a525ef34dec1c381f2b6 - rtla/tests: Add unit tests for actions module

Fri, 24 Apr 2026 16:02:44 +0200

rtla/tests: Add unit tests for actions moduleAdd unit tests covering all functions in the actions module, includingboth valid and invalid inputs and all action types, except foractions_perform(), where only shell and continue actions are tested.To support testing multiple modules, the unit test build was modified sothat it links the entire rtla-in.o file. For this to work, the main()function in rtla.c was declared weak, so that the unit test main is ableto override it.Other included minor changes to unit tests are:- Make unit test output verbose to show which tests are being run, now that we have more than 3 tests.- Add unit_tests file to .gitignore.- Split unit test sources to one file per test suite, and keep only main() function in unit_tests.c.- Fix Makefile dependencies so that "make unit-tests" will rebuild the binary with the changes in the commit.Also with the linking the entire rtla-in.o file, it now has rtla'snr_cpus symbol, so the declaration in utils unit tests is made extern.Assisted-by: Composer:composer-2-fastLink: https://lore.kernel.org/r/20260424140244.958495-1-tglozar@redhat.comSigned-off-by: Tomas Glozar List of files: /linux/tools/tracing/rtla/tests/unit/Build
