The sources for the powerpc selftests are arranged into sub-directories. However when the tests are built and installed, the sub-directories are squashed, losing the structure. For example, with the current code the result of installing the selftests is: $ tree tools/testing/selftests/kselftest_install tools/testing/selftests/kselftest_install ├── kselftest │ ├── ktap_helpers.sh │ ├── module.sh │ ├── prefix.pl │ └── runner.sh ├── kselftest-list.txt ├── powerpc │ ├── alignment_handler │ ├── attr_test │ ├── back_to_back_ebbs_test │ ├── bad_accesses │ ├── bhrb_filter_map_test │ ├── bhrb_no_crash_wo_pmu_test │ ├── blacklisted_events_test │ ├── cache_shape │ ├── close_clears_pmcc_test │ ├── context_switch │ ├── copy_first_unaligned ... │ ├── settings ... │ └── wild_bctr └── run_kselftest.sh All the powerpc tests are squashed into the single powerpc directory. In particular, note that there is a single `settings` file, even though there are multiple settings files in the powerpc selftest sources. One of the settings files ends up installed, depending on install order, even if they have different contents. Similarly if there were two tests with the same name in different sub-directories they would clobber each other. Fix it by replicating the directory structure of the source tree into the install directory. The result being for example: $ tree tools/testing/selftests/kselftest_install tools/testing/selftests/kselftest_install ├── kselftest │ ├── ktap_helpers.sh │ ├── module.sh │ ├── prefix.pl │ └── runner.sh ├── kselftest-list.txt ├── powerpc │ ├── alignment │ │ ├── alignment_handler │ │ └── copy_first_unaligned │ ├── benchmarks │ │ ├── context_switch │ │ ├── exec_target │ │ ├── fork │ │ ├── futex_bench │ │ ├── gettimeofday │ │ ├── mmap_bench │ │ ├── null_syscall │ │ └── settings ... │ ├── eeh │ │ ├── eeh-basic.sh │ │ ├── eeh-functions.sh │ │ └── settings ... │ └── vphn │ └── test-vphn └── run_kselftest.sh Note multiple settings files in different sub-directories. This change also has the effect of changing the names of the tests from the point of view of the kselftest runner. Before the tests are named eg: powerpc:copy_first_unaligned powerpc:cache_shape powerpc:reg_access_test After, the test collection names include the sub-directory: powerpc/alignment:copy_first_unaligned powerpc/cache_shape:cache_shape powerpc/pmu/ebb:reg_access_test That means whereas previously all powerpc tests could be run with: $ ./run_kselftest.sh -c powerpc After the change it's necessary to pass a regex that matches all powerpc entries, eg: $ ./run_kselftest.sh -c "powerpc.*" The latter form also works before and after the change.
