EMIT_TESTS which is the common function that implements run_tests target, treats all non-zero return codes from tests as failures. When tests are skipped with non-zero return code, because of unmet dependencies and/or unsupported configuration, it reports them as failed. This will lead to too many false negatives even on the tests that couldn't be run. EMIT_TESTS is changed to test for SKIP=4 return from tests to enable the framework for individual tests to return special SKIP code. Tests will be changed as needed to report SKIP instead FAIL/PASS when they get skipped. Currently just the test name is printed in the RUN_TESTS output. For example, when raw_skew sub-test from timers tests in run, the output shows just raw_skew. Include main test name when printing sub-test results. In addition, remove duplicate strings for printing common information with a new for the test header information. With this change run_kelftest.sh output for breakpoints test will be: TAP version 13 Running tests in breakpoints ======================================== selftests: breakpoints: step_after_suspend_test not ok 1..1 selftests: breakpoints: step_after_suspend_test [SKIP] selftests: breakpoints: breakpoint_test ok 1..2 selftests: breakpoints: breakpoint_test [PASS] Signed-off-by: Shuah Khan (Samsung OSG) <shuah@kernel.org>
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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
