[PATCH 1/9] selftests: Introduce minimal shared logic for running tests

[PATCH 1/9] selftests: Introduce minimal shared logic for running tests

[Michael Ellerman]

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 u+x to several.

This adds a Make include file which most selftests can then include to

We use a variable to hold the default implementation of $(RUN_TESTS)

[PATCH 2/9] selftests: Add install target

[Michael Ellerman]

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.

Michael,

Did you happen to run run_kselftest.sh from the install
directory to make sure all the dependent executables
are installed? You are missing a few required dependencies.
efivars test for example.

Please run kselftest_install.sh I sent out for review and
compare the following:

- contents of install directory created with your patch vs.
  my kselftest_install.sh tool
- Compare your run_kselftest.sh run with the one that gets
  generated with my kselftest_install.sh tool

General rule is all tests that get run when run_tests target
is run should run from the install directory using the
run_kselftest.sh generated during install.

Couple more things. Please change the install directory name
to kselftest

tools/testing/selftests/kselftest
instead of
tools/testing/selftests/install

Also please flatten the directory structure under the install
directory. I don't see any value in creating directory for each
test for install. Also it is makes it cumbersome for users
to navigate and work with after the install. This would mean cpu
and memory hot-plug scripts need unique names.

I prefer install, that's what it is after all. I don't know why you're so
obsessed with the "kselftest" name.

That's not a good idea. To start with different tests might the same name, as
already happens with the memory & cpu hot-plug tests. They may also have data
files that would clobber each other. We'd need to make sure all files used in
all tests have different names, that would be a total mess.

cheers

It is the overall user-interface. I want to be able to call
install wrapper script and have the right directory generated.
If user passes in /tmp for example as a main directory, install
is so generic and doesn't make sense. I see that you sent the
patch v4 still with install and please change it to kselftest

No I want the just one container directory for the tests. Again I am
looking at the bigger picture user-interface angle. Please flatten it,
and resend it.

I responded to your patch v4. Please re-do the patch to address my
comments if you want your patch to be included.

It is the overall user-interface. I want to be able to call
install wrapper script and have the right directory generated.
If user passes in /tmp for example as a main directory, install
is so generic and doesn't make sense. I see that you sent the
patch v4 still with install and please change it to kselftest

No I want the just one container directory for the tests. Again I am
looking at the bigger picture user-interface angle. Please flatten it,
and resend it.

I responded to your patch v4. Please re-do the patch to address my
comments if you want your patch to be included.

Weird, I don't see that.

  $ make install
  $ head install/run_kselftest.sh
  #!/bin/bash
  
  
  cd $(dirname $0)


Does it depend on the shell? I guess none of the newlines are necessary so I'll
just remove them.

cheers

Dunno, bash here too. Maybe the version ? My environment at the office is a little

[PATCH 3/9] selftests: Add install support for the powerpc tests

[Michael Ellerman]

The bulk of the selftests are actually below the powerpc sub directory.

This adds support for installing them, when on a powerpc machine, or if
ARCH and CROSS_COMPILE are set appropriately.

This is a little more complicated because of the sub directory structure
under powerpc, but much of the common logic in lib.mk is still used. The
net effect of the patch is still a reduction in code.

[PATCH 4/9] kbuild: add a new kselftest_install make target to install selftests

[Michael Ellerman]

Add a new make target to install kernel selftests. This new target will
build and install selftests.

The default is just $(objtree)/selftests. This is preferable to
something based on $(INSTALL_MOD_PATH) (which defaults to /), as it
allows a normal user to install the tests. This is similar to the
default behaviour of make headers_install.

Therefore the most basic usage is:

$ make kselftests_install
$ ./selftests/all.sh

To install elsewhere use:

$ make kselftests_install INSTALL_SELFTESTS_PATH=/some/where
$ /some/where/all.sh

[PATCH 5/9] kbuild: Don't pass -rR to selftest makefiles

[Michael Ellerman]

The makefiles under tools/testing/selftests are not real kbuild
makefiles, they are regular stand alone makefiles. As such they *do*
want all the standard implicit rules and variables defined.

So before calling those makefiles, filter -rR out of MAKEFLAGS.

Without this not all the selftests are built correctly when called via
the top-level Makefile.

[PATCH 7/9] selftests/timers: Use implicit rules

[Michael Ellerman]

There's no need to open-code the build rules, use the implicit ones.

This has the nice side effect of enabling cross compilation.
