selftests/powerpc: Fix remaining fallout from recent changes

2017-02-14T15:02:27+00:00

In benchmarks we need to use $(TEST_GEN_PROGS) after we include lib.mk, because lib.mk does the substitution to add $(OUTPUT). In math the vmx and fpu names were typoed so they no longer matched correctly, put back the 'v' and 'f'. In tm we need to substitute $(OUTPUT) into SIGNAL_CONTEXT_CHK_TESTS so that the rule matches. In pmu there is an extraneous ':' on the end of $$BUILD_TARGET for the clean and install rules, which breaks the logic in the child Makefiles.

selftests: enable O and KBUILD_OUTPUT

2017-01-05T20:42:22+00:00

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. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests: remove duplicated all and clean target

2017-01-05T20:41:35+00:00

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. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests/powerpc: Move shared headers into new include dir

2016-11-17T06:11:47+00:00

There are some functions, especially register related, which can be shared across multiple selftests/powerpc test directories. This patch creates a new include directory to store those shared files, so that the file layout becomes more neat.

selftests/powerpc: Add missing binaries to .gitignores

Some of the recent new selftests were missing additions to .gitignore, add them now. Signed-off-by: Michael Ellerman

selftests/powerpc: Rework FPU stack placement macros and move to header file

2016-10-04T09:10:11+00:00

The FPU regs are placed at the top of the stack frame. Currently the position expected to be passed to the macro. The macros now should be passed the stack frame size and from there they can calculate where to put the regs, this makes the use simpler. Also move them to a header file to be used in an different area of the powerpc selftests Signed-off-by: Cyril Bur Signed-off-by: Michael Ellerman

selftests/powerpc: Check for VSX preservation across userspace preemption

2016-10-04T09:10:09+00:00

Ensure the kernel correctly switches VSX registers correctly. VSX registers are all volatile, and despite the kernel preserving VSX across syscalls, it doesn't have to. Test that during interrupts and timeslices ending the VSX regs remain the same. Signed-off-by: Cyril Bur Signed-off-by: Michael Ellerman
