selftests: remove duplicated all and clean target Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt.

selftests/powerpc: Add a test of the switch_endian() syscall This adds a test of the switch_endian() syscall we added in the previous commit. We test it by calling the endian switch syscall, and then executing some code in the other endian to check everything went as expected. That code checks registers we expect to be maintained are. If the endian switch failed to happen that code sequence will be illegal and cause the test to abort. We then switch back to the original endian, do the same checks and finally write a success message and exit(0). Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> 2015-03-28 10:35:17 +00:00

selftests: enable O and KBUILD_OUTPUT Enable O and KBUILD_OUTPUT for kselftest. User could compile kselftest to another directory by passing O or KBUILD_OUTPUT. And O is high priority than KBUILD_OUTPUT.

selftests: add EXTRA_CLEAN for clean target Some testcases need the clean extra data after running. This patch introduce the "EXTRA_CLEAN" variable to address this requirement. After KBUILD_OUTPUT is enabled in later patch, it will be easy to decide to if we need do the cleanup in the KBUILD_OUTPUT path(if the testcase ran immediately after compiled).
