The benchmark command handling (-b) in resctrl selftests is overly complicated code. This series turns the benchmark command immutable to preserve it for all selftests and improves benchmark command related error handling. This series also ends up removing the strcpy() calls which were pointed out earlier. v3: - Removed DEFAULT_SPAN_STR for real and the duplicated copy of defines that made to v2 likely due to my incorrect conflict resolutions v2: - Added argument length check into patch 1/7 - Updated also -b line in help message. - Document -b argument related "algorithm" - Use asprintf() to convert defined constant int to string - Improved changelog texts - Added \n to ksft_exit_fail_msg() call messages. - Print DEFAULT_SPAN with %u instead of %zu to avoid need to cast it Ilpo Järvinen (7): selftests/resctrl: Ensure the benchmark commands fits to its array selftests/resctrl: Correct benchmark command help selftests/resctrl: Remove bw_report and bm_type from main() selftests/resctrl: Simplify span lifetime selftests/resctrl: Make benchmark command const and build it with pointers selftests/resctrl: Remove ben_count variable selftests/resctrl: Cleanup benchmark argument parsing tools/testing/selftests/resctrl/cache.c | 5 +- tools/testing/selftests/resctrl/cat_test.c | 13 +- tools/testing/selftests/resctrl/cmt_test.c | 34 +++-- tools/testing/selftests/resctrl/mba_test.c | 4 +- tools/testing/selftests/resctrl/mbm_test.c | 7 +- tools/testing/selftests/resctrl/resctrl.h | 17 ++- .../testing/selftests/resctrl/resctrl_tests.c | 120 +++++++++--------- tools/testing/selftests/resctrl/resctrl_val.c | 10 +- 8 files changed, 120 insertions(+), 90 deletions(-) -- 2.30.2
