2017-01-05selftests: add default rules for c source filebamvor.zhangjian@huawei.com1-11/+6
There are difference rules for compiling c source file in different testcases. In order to enable KBUILD_OUTPUT support in later patch, this patch introduce the default rules in "tools/testing/selftest/lib.mk" and remove the existing rules in each testcase.

2017-01-05selftests: remove duplicated all and clean targetbamvor.zhangjian@huawei.com1-14/+10
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.

2015-11-05selftests: vm: add tests for lock on faultEric B Munson1-0/+2
Test the mmap() flag, and the mlockall() flag. These tests ensure that pages are not faulted in until they are accessed, that the pages are unevictable once faulted in, and that VMA splitting and merging works with the new VM flag. The second test ensures that mlock limits are respected. Note that the limit test needs to be run a normal user. Also add tests to use the new mlock2 family of system calls.

2015-09-22userfaultfd: selftests: vm: pick up sanitized kernel headersThierry Reding1-1/+1
Add the usr/include subdirectory of the top-level tree to the include path, and make sure to include headers without relative paths to make sure the sanitized headers get picked up. Otherwise the compiler will not be able to find the linux/compiler.h header included by the non- sanitized include/uapi/linux/userfaultfd.h. While at it, make sure to only hardcode the syscall numbers on x86 and PowerPC if they haven't been properly picked up from the headers.

This manually reverts 7e50533d4b842 ("selftests: add hugetlbfstest"). The hugetlbfstest test depends on hugetlb pages being counted in a task's rss. This functionality is not in the kernel, so the test will always fail. Remove test to avoid confusion.

2015-05-26Test compaction of mlocked memorySri Jayaramappa1-1/+6
Commit commit 5bbe3547aa3b ("mm: allow compaction of unevictable pages") introduced a sysctl that allows userspace to enable scanning of locked pages for compaction. This patch introduces a new test which fragments main memory and attempts to allocate a number of huge pages to exercise this compaction logic. Tested on machines with up to 32 GB RAM. With the patch a much larger number of huge pages can be allocated than on the kernel without the patch. Example output: On a machine with 16 GB RAM: sudo make run_tests vm ... ----------------------- running compaction_test ----------------------- No of huge pages allocated = 3834 [PASS] ...

2015-03-19selftests: Set CC using CROSS_COMPILE once in lib.mkMichael Ellerman1-1/+0
This avoids repeating the logic in every Makefile. We mimic the top-level Makefile and use $(CROSS_COMPILE)gcc. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
2015-03-13selftests: Add install targetMichael Ellerman1-0/+1
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.

2015-03-13selftests: Introduce minimal shared logic for running testsMichael Ellerman1-2/+3
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.

2012-03-28mm: move hugepage test examples to tools/testing/selftests/vmDave Young1-0/+14
hugepage-mmap.c, hugepage-shm.c and map_hugetlb.c in Documentation/vm are simple pass/fail tests, It's better to promote them to tools/testing/selftests. Thanks suggestion of Andrew Morton about this. They all need firstly setting up proper nr_hugepages and hugepage-mmap need to mount hugetlbfs. So I add a shell script run_vmtests to do such work which will call the three test programs and check the return value of them. Changes to original code including below: a. add run_vmtests script b. return error when read_bytes mismatch with writed bytes. c. coding style fixes: do not use assignment in if condition [akpm@linux-foundation.org: build the targets before trying to execute them] [akpm@linux-foundation.org: Documentation/vm/ no longer has a Makefile.
