selftests: remove duplicated all and clean target

2017-01-05T20:41:35Z

Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests: Add missing #include directives

2015-11-03T23:53:53Z

Several C programs fail to include the headers declaring all the functions they call, resulting in warnings or errors. After this, memfd_test.c is still missing some function declarations but can't easily get them because of a conflict between and . Signed-off-by: Ben Hutchings Signed-off-by: Shuah Khan

selftests: mqueue: simplify the Makefile

2015-09-14T22:43:24Z

Use make's implict rule for building simple C programs. Suggested-by: Michael Ellerman Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests: mqueue: allow extra cflags

2015-09-14T22:42:55Z

Change from = to += in order to allows the user to pass whatever CFLAGS they wish(E.g. pass the proper headers and librareis (popt.h and libpopt.so) in cross-compiling) Suggested-by: Michael Ellerman Signed-off-by: Bamvor Jian Zhang Acked-by: Michael Ellerman Signed-off-by: Shuah Khan

selftest/mqueue: enable cross compilation

2015-04-02T18:41:58Z

Use the CC variable instead of hard coding gcc. Also clean up the compiler options by creating a CFLAGS variable. Signed-off-by: Tyler Baker Signed-off-by: Shuah Khan

selftests: Add install target

2015-03-13T21:21:56Z

This adds make install support to selftests. The basic usage is: $ cd tools/testing/selftests $ make install That installs into tools/testing/selftests/install, which can then be copied where ever necessary. The install destination is also configurable using eg: $ INSTALL_PATH=/mnt/selftests make install The implementation uses two targets in the child makefiles. The first "install" is expected to install all files into $(INSTALL_PATH). The second, "emit_tests", is expected to emit the test instructions (ie. bash script) on stdout. Separating this from install means the child makefiles need no knowledge of the location of the test script. Signed-off-by: Michael Ellerman Signed-off-by: Shuah Khan

selftests: Introduce minimal shared logic for running tests

2015-03-13T21:13:40Z

This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

tools: testing: selftests: mq_perf_tests: Fix infinite loop on ARM

2015-01-06T19:55:21Z

We can't use a char type to check for a negative return value since char isn't guaranteed to be signed. Indeed, the char type tends to be unsigned on ARM. Signed-off-by: dann frazier Signed-off-by: Shuah Khan
