Currently print_overall_results prints the number of fails in the summary, example from base_probe tests in testsuite_probe: ## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY :: 11 failures found test_invalid_options contains multiple tests and out of that 11 failed. Sometimes it could happen that it is due to missing dependency in the build or environment dependency. Example, perf probe -L requires DWARF enabled. otherwise it fails as below: ./perf probe -L Error: switch `L' is not available because NO_DWARF=1 "-L" is tested as one of the option in: for opt in '-a' '-d' '-L' '-V'; do <<perf probe test>> print_results $PERF_EXIT_CODE $CHECK_EXIT_CODE "missing argument for $opt" Here -a and -d doesn't require DWARF. Similarly there are few other tests requiring DWARF. To hint the user that missing DWARF could be one issue, update print_overall_results to print a comment string along with summary hinting the possible cause. Update test_invalid_options.sh and test_line_semantics.sh to pass the info about DWARF requirement since these tests failed when perf is built without DWARF. Use the check for presence of DWARF with "perf check feature" and append the hint message based on the result. With the change: ## [ FAIL ] ## perf_probe :: test_invalid_options SUMMARY :: 11 failures found :: Some of the tests need DWARF to run Reviewed-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Disha Goel <disgoel@linux.vnet.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Madhavan Srinivasan <maddy@linux.ibm.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Veronika Molnarova <vmolnaro@redhat.com> Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20241206135254.35727-1-atrajeev@linux.vnet.ibm.com [ Minor edits changing "dwarf" to "DWARF" as its an acronym ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
