selftests: set the BUILD variable to absolute path

2023-01-18T10:42:00+00:00

commit 5ad51ab618de5d05f4e692ebabeb6fe6289aaa57 upstream.

The build of kselftests fails if relative path is specified through
KBUILD_OUTPUT or O= method. BUILD variable is used to determine
the path of the output objects. When make is run from other directories
with relative paths, the exact path of the build objects is ambiguous
and build fails.

	make[1]: Entering directory '/home/usama/repos/kernel/linux_mainline2/tools/testing/selftests/alsa'
	gcc     mixer-test.c -L/usr/lib/x86_64-linux-gnu -lasound  -o build/kselftest/alsa/mixer-test
	/usr/bin/ld: cannot open output file build/kselftest/alsa/mixer-test

Set the BUILD variable to the absolute path of the output directory.
Make the logic readable and easy to follow. Use spaces instead of tabs
for indentation as if with tab indentation is considered recipe in make.

selftests: Fix kselftest O=objdir build from cluttering top level objdir

2023-01-18T10:42:00+00:00

commit 29e911ef7b706215caf02a82b0d3076611d6abe8 upstream.

make kselftest-all O=objdir builds create generated objects in objdir.
This clutters the top level directory with kselftest objects. Fix it
to create sub-directory under objdir for kselftest objects.

kselftest: Fix NULL INSTALL_PATH for TARGETS runlist

2019-12-13T07:43:31+00:00

[ Upstream commit 02bf1f8b3c43eec5053c35c14fb9f138186b4123 ]

As per commit 131b30c94fbc ("kselftest: exclude failed TARGETS from
runlist") failed targets were excluded from the runlist. But value
$$INSTALL_PATH is always NULL. It should be $INSTALL_PATH instead
$$INSTALL_PATH.

So, fix Makefile to use $INSTALL_PATH.

kselftest: exclude failed TARGETS from runlist

2019-10-01T19:28:38+00:00

A TARGET which failed to be built/installed should not be included in the
runlist generated inside the run_kselftest.sh script.

kselftest: add capability to skip chosen TARGETS

2019-10-01T19:19:04+00:00

Let the user specify an optional TARGETS skiplist through the new optional
SKIP_TARGETS Makefile variable.

It is easier to skip at will using a reduced and well defined list of
possibly problematic targets with SKIP_TARGETS than to provide a partially
stripped down list of good targets using the usual TARGETS variable.

selftests: Add kselftest-all and kselftest-install targets

2019-10-01T16:11:08+00:00

Add kselftest-all target to build tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.

Current kselftest target builds and runs tests on a development
system which is a developer use-case.

Add kselftest-install target to install tests from the top level
Makefile. This is to simplify kselftest use-cases for CI and
distributions where build and test systems are different.

This change addresses requests from developers and testers to add
support for installing kselftest from the main Makefile.

In addition, make the install directory the same when install is
run using "make kselftest-install" or by running kselftest_install.sh.
Also fix the INSTALL_PATH variable conflict between main Makefile and
selftests Makefile.

selftests: use "$(MAKE)" instead of "make"

2019-08-19T20:21:36+00:00

When doing "make kselftest TARGETS=bpf -j12", bpf progs end up being
compiled sequentially and thus slowly.

The reason is that parent make (tools/testing/selftests/Makefile) does
not share its jobserver with child make
(tools/testing/selftests/bpf/Makefile), therefore the latter runs with
-j1.

Change all instances of "make" to "$(MAKE)", so that the whole make
hierarchy runs using a single jobserver.

kbuild: replace KBUILD_SRCTREE with boolean building_out_of_srctree

2019-07-10T15:05:09+00:00

Commit 25b146c5b8ce ("kbuild: allow Kbuild to start from any directory")
deprecated KBUILD_SRCTREE.

It is only used in tools/testing/selftest/ to distinguish out-of-tree
build. Replace it with a new boolean flag, building_out_of_srctree.

I also replaced the conditional ($(srctree),.) because the next commit
will allow an absolute path to be used for $(srctree) even when building
in the source tree.

selftests: avoid KBUILD_OUTPUT dir cluttering with selftest objects

2019-05-14T23:37:41+00:00

Running "make kselftest" or building selftests when KBUILD_OUTPUT
is set, will create selftest objects in the KBUILD_OUTPUT directory.
This could be undesirable especially when user didn't intend to
relocate selftest objects.

Use KBUILD_OUTPUT/kselftest to create selftest objects instead of
cluttering the main directory.

selftests: fix install target to use default install path

2019-05-09T15:48:47+00:00

Install target fails when INSTALL_PATH is undefined. Fix install target
to use "output_dir/install as the default install location. "output_dir"
is either the root of selftests directory under kernel source tree or
output directory specified by O= or KBUILD_OUTPUT.

e.g:
make -C tools/testing/selftests install


make O=/tmp/kselftest -C tools/testing/selftests install


export KBUILD_OUTPUT=/tmp/kselftest
make -C tools/testing/selftests install


In addition, add "all" target as dependency to "install" to build and
install using a single command.
