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 v4 2/9] kbuild: Don't pass LDFLAGS to selftest Makefile
@ 2015-03-11 4:05 ` Michael Ellerman

The makefile in arch/x86/Makefile.um sets LDFLAGS and exports it, which
is then propagated to the selftest Makefiles and leads to build errors
there. The build errors occur because we are passing LDFLAGS to CC, but
the option set in Makefile.um (-m elf_x86_64) is not understood by CC.
We could fix that by using -Wl, but that might break the UM build if
it's actually passing that option to LD directly.
We don't actually want the LDFLAGS from kbuild in the selftest Makefile,
so the simplest fix seems to be to clear LDFLAGS before invoking the
selftest Makefile.

* [PATCH v4 3/9] selftests: Introduce minimal shared logic for running tests
2015-03-11 4:05 ` Michael Ellerman
@ 2015-03-11 4:05 ` 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 a+x to several.

v3: Rebase onto 4.0-rc2, add +x to more scripts that need it.
v4: Rebase onto 4.0-rc3.

* [PATCH v4 3/9] selftests: Introduce minimal shared logic for running tests
@ 2015-03-11 4:05 ` Michael Ellerman
0 siblings, 0 replies; 47+ messages in thread
From: Michael Ellerman @ 2015-03-11 4:05 UTC (permalink / raw)
To: shuahkh; +Cc: linux-kernel, davej, mmarek, linux-api
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.
Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
---
v3: Rebase onto 4.0-rc2, add +x to more scripts that need it.
v4: Rebase onto 4.0-rc3.

* [PATCH v4 4/9] selftests: Add install target
2015-03-11 4:05 ` Michael Ellerman
@ 2015-03-11 4:06 ` Michael Ellerman

From: Michael Ellerman @ 2015-03-11 4:06 UTC (permalink / raw)
To: shuahkh; +Cc: linux-kernel, davej, mmarek, linux-api
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 <mpe@ellerman.id.au>
---
v3: Rebase onto 4.0-rc2.
Rename all.sh to run_kselftest.sh.
Add --no-print-directory to emit_tests invocation.
v4: Rebase onto 4.0-rc3, add TEST_FILES to efivars and vm tests, remove
newlines from echoes.

* [PATCH v4 4/9] selftests: Add install target
@ 2015-03-11 4:06 ` Michael Ellerman
0 siblings, 0 replies; 47+ messages in thread
From: Michael Ellerman @ 2015-03-11 4:06 UTC (permalink / raw)
To: shuahkh; +Cc: linux-kernel, davej, mmarek, linux-api
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.

v3: Rebase onto 4.0-rc2.
Rename all.sh to run_kselftest.sh.
Add --no-print-directory to emit_tests invocation.
v4: Rebase onto 4.0-rc3, add TEST_FILES to efivars and vm tests, remove
newlines from echoes.

* [PATCH v4 5/9] selftests: Add install support for the powerpc tests

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 v4 5/9] selftests: Add install support for the powerpc tests
@ 2015-03-11 4:06 ` Michael Ellerman

From: Michael Ellerman @ 2015-03-11 4:06 UTC (permalink / raw)
To: shuahkh; +Cc: linux-kernel, davej, mmarek, linux-api
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.

This avoids repeating the logic in every Makefile. We mimic the
top-level Makefile and use $(CROSS_COMPILE)gcc.

There's no need to open-code the build rules, use the implicit ones.
This has the nice side effect of enabling cross compilation.

There's no need to open-code the build rules, use the implicit ones.
This has the nice side effect of enabling cross compilation.

I don't see my comments addressed. If you want me to take
this work, please address the following comments:
- Name install directory kselftest. It should work with the
the use-case.
make INSTALL_PATH=/tmp make install
The install directory should be /tmp/kselftest
- Flatten the directory with all tests under /tmp/kselftest
I am wasting lot of time because you don't fully address my
comments and send patches that dont' work correctly. Please
make sure your patches don't generate work for me.

Yes. There is the issue of duplicate executable names and data
file to be concerned about. It is a name-space problem. It is
not unique to this case, example /usr/bin. This problem is better
solved without adding the complexity of hierarchical directory
structure.
1. Individual test Makefiles ensure unique names for their
executables and data files. This can be done as a process
when new tests are accepted.
2. Install process makes sure they are unique - this patch is
solving the problem by creating a directory hierarchy. A simpler
way to do it is by adding pre-fix to when there is name space
conflict.
The problem with directory hierarchy is for one thing:
1. It is complex and way too many directories get created during
install and this problem will mushroom as more and more tests
get added.
2. User won't be able to define a simple path variable to invoke
individual tests. This is a user experience problem.
Please find a way to solve the name-space problem without the
complexity of directory hierarchy.

Does this work on x86, powerpc, and other architectures? Do all tests

One directory is created for each test directory under selftests. That's not
"way too many" directories.
Why does it make sense to have directories for the selftest sources, but not
the installed tests? Why don't we just put all the tests in one directory under
selftests? A: Because that would be stupid.

Who cares? No one does that. Many of the tests aren't just simple executables
that can be run via $PATH, they require test files in the current directory.

One directory is created for each test directory under selftests. That's not
"way too many" directories.
Why does it make sense to have directories for the selftest sources, but not
the installed tests? Why don't we just put all the tests in one directory under
selftests? A: Because that would be stupid.

You're wasting a lot of time? You have got to be kidding me. You are wasting a
lot of *my* time.
You have my patches, they're signed off, you can do what you wish with them.
Good luck.

This is getting silly. We've spent three months arguing over shell
scripts and makefiles for what should be a trivial feature.
We make fundamental changes to the VM code with less contention.
It's not helped that timezones are working against everyone here,
so even minor changes end up taking a while to get reposted, re-reviewed
etc, but the level of pushback because something isn't perfect is absurd,
especially when we're talking about new features.
If you want the in-kernel variant to be perfect every step of the way,
and move slowly and never introduce subtle breakage along the way that then
gets fixed up in subsequent changes, maybe a faster moving external project
that syncs up with the kernel tree is the way forward.
If kselftests is going to evolve into something useful, something has to change.

I really don't think this process has to this contentious. I don't
believe the changes I am asking for are unreasonable.

Directory structure might seem like a trivial problem, however it is
important to get the user interface right.
Since Michael doesn't have the bandwidth to make the suggested changes,
I working on applying his patches. There are some conflicts with the
selftests: Introduce minimal shared logic for running tests
selftests: Add install target
patches and timer patches. I can fix the directory hierarchy after
I get these two patches into next.

Thanks for finding the problem and fix. I want to handle this in
the selftests/Makefile level instead. I have a patch ready to send
out for review.

This patch is now in linux-kselftest next. Could you please review
to make sure, it looks right. I had to drop the shared logic from
timers Makefile because, it changed considerably with the additional
tests and it wasn't easy to resolve the conflict and keep both changes.
So at the moment, timers doesn't use the shared logic.
If lib.mk could provide a way to run additional programs that require
arguments in addition to RUN_TESTS. In the case of timers, there is one
test that requires arguments. In some cases, e.g: memory hotplug,
override works well since it is just one executable. In this case,
there is a mix.
Something that can be addressed in a separate patch. For now, I made
the decision to apply with shared logic patch minus the changes to
use lib.mk

ok. linux-kselftest next has both shared logic and install patches
now. As I mentioned in my reply to shared logic patch, I had to drop
the changes to timers Makefile to add shared logic, hence timers progs
don't get installed at the moment.
Could you please review to make sure, it looks right.
As I said in the other email, if lib.mk could provide a way to run
additional programs that require arguments in addition to RUN_TESTS.
In the case of timers, there is one test that requires arguments. In
some cases, e.g: memory hotplug, override works well since it is just
one executable. In this case, there is a mix of executables that don't
need any special handling and some that need it.
You are welcome to add shared logic and install to timers if you would
like.

I managed to get this taken care of before my weekend. You will see two
patches one with changes to lib.mk to add additional variables to avoid
overrides for cases like timers, and the other that updates timers to
use shared logic.
I did quick test running both make run_tests and make install to verify
timers programs are installed and run_tests works correctly.

Thanks, looks good to me.
Can you also apply the patch to install the powerpc tests, or was there a
problem with it? It seems to apply cleanly for me.

And also 6/9 "selftests: Set CC using CROSS_COMPILE once in lib.mk" would be
nice and is uncontroversial, I think:
