15 code that can still test an older kernel and make sure it skips the test
39   $ make headers
40   $ make -C tools/testing/selftests
44   $ make -C tools/testing/selftests run_tests
48   $ make kselftest
60   $ make O=/tmp/kselftest kselftest
64   $ export KBUILD_OUTPUT=/tmp/kselftest; make kselftest
70 Kselftest supports "summary" option to make it easier to understand the test
77   $ make summary=1 kselftest
82 You can use the "TARGETS" variable on the make command line to specify
87   $ make -C tools/testing/selftests TARGETS=ptrace run_tests
91   $  make TARGETS="size timers" kselftest
95   $ make O=/tmp/kselftest TARGETS="size timers" kselftest
99   $ export KBUILD_OUTPUT=/tmp/kselftest; make TARGETS="size timers" kselftest
101 Additionally you can use the "SKIP_TARGETS" variable on the make command
106   $ make -C tools/testing/selftests SKIP_TARGETS=ptrace run_tests
110   $  make SKIP_TARGETS="size timers" kselftest
115   $  make TARGETS="breakpoints size timers" SKIP_TARGETS=size kselftest
125   $ make -C tools/testing/selftests hotplug
129   $ make -C tools/testing/selftests run_hotplug
137 You can use the "install" target of "make" (which calls the `kselftest_install.sh`
139 or in a user specified location via the `INSTALL_PATH` "make" variable.
143    $ make -C tools/testing/selftests install
147    $ make -C tools/testing/selftests install INSTALL_PATH=/some/other/path
200    $ make -C tools/testing/selftests gen_tar
204 specifying a `FORMAT` make variable. Any value recognized by `tar's auto-compress`_
207     $ make -C tools/testing/selftests gen_tar FORMAT=.xz
209 `make gen_tar` invokes `make install` so you can use it to package a subset of
213     $ make -C tools/testing/selftests gen_tar TARGETS="size" FORMAT=.xz
228  * Don't cause the top-level "make run_tests" to fail if your feature is
307     make -C tools/testing/selftests {all,install,clean,gen_tar}
308     make -C tools/testing/selftests {all,install,clean,gen_tar} O=abs_path
309     make -C tools/testing/selftests {all,install,clean,gen_tar} O=rel_path
353    make kselftest-merge
354    make modules
355    sudo make modules_install
356    make TARGETS=lib kselftest
