selftest/mqueue: enable cross compilation

2015-04-02T18:41:58+00:00

Use the CC variable instead of hard coding gcc. Also clean up the compiler
options by creating a CFLAGS variable.

selftests: Add install target

2015-03-13T21:21:56+00:00

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.

selftests: Introduce minimal shared logic for running tests

2015-03-13T21:13:40+00:00

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: Fix mqueue Makefile compile linking order

2014-07-12T01:11:18+00:00

Makefile compile linking order is incorrect causing the compile

mqueue selftests: print failure status instead of cause make error

2012-12-18T01:15:26+00:00

Original behavior:
  bash-4.1$ make -C mqueue run_tests
  make: Entering directory `/home/dave/git/linux-2.6/tools/testing/selftests/mqueue'
  ./mq_open_tests /test1
  Not running as root, but almost all tests require root in order to modify
  system settings.  Exiting.
  make: *** [run_tests] Error 1
  make: Leaving directory `/home/dave/git/linux-2.6/tools/testing/selftests/mqueue'

After applying the patch:
  bash-4.1$ make -C mqueue run_tests
  make: Entering directory `/home/dave/git/linux-2.6/tools/testing/selftests/mqueue'
  Not running as root, but almost all tests require root in order to modify
  system settings.  Exiting.
  mq_open_tests: [FAIL]

tools/selftests: add mq_perf_tests

2012-06-01T00:49:31+00:00

Add the mq_perf_tests tool I used when creating my mq performance patch.
Also add a local .gitignore to keep the binaries from showing up in git
status output.
