selftests/powerpc: Move shared headers into new include dir

2016-11-17T06:11:47Z

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: Compile selftests against headers without AT_HWCAP2

2016-09-23T12:36:05Z

It might be nice to compile selftests against older kernels and headers but which may not have HWCAP2. Signed-off-by: Cyril Bur Signed-off-by: Michael Ellerman

selftests/powerpc: Add a test for PROT_SAO

2016-07-14T10:26:25Z

PROT_SAO is a powerpc-specific flag to mmap(), and we rely on arch specific logic to allow it to be passed to mmap(). Add a small test to ensure mmap() accepts PROT_SAO. We don't have a good way to test that it actually causes the mapping to be created with the right flags, so for now we just touch the mapping so it's faulted in. In future we might be able to do something better. Signed-off-by: Michael Ellerman

selftests/powerpc: Make reg.h common to all powerpc selftests

2016-05-11T11:54:12Z

Currently there is a reg.h in pmu/ebb that has defines that are useful in other powerpc selftests so move this up into selftests/powerpc folder. Also include in utils.h - as this is often used in self tests. Add in some other useful register defines. Signed-off-by: Rashmica Gupta Signed-off-by: Michael Ellerman

selftests/powerpc: Test cp_abort during context switch

2016-05-11T11:54:01Z

Test that performing a copy paste sequence in userspace on P9 does not result in a leak of the copy into the paste of another process. This is based on Anton Blanchard's context_switch benchmarking code. It sets up two processes tied to the same CPU, one which copies and one which pastes. The paste should never succeed and the test fails if it does. This is a test for commit, "8a64904 powerpc: Add support for userspace P9 copy paste."

selftests/powerpc: Move pick_online_cpu() up into utils.c

2015-12-16T23:46:41Z

We want to use this in another test, so make it available at the top of the powerpc selftests tree. Signed-off-by: Michael Ellerman

selftests/powerpc: Add have_hwcap2() helper

2015-12-14T09:41:47Z

We already do this twice and want to add another so add a helper. Signed-off-by: Michael Ellerman

selftests/powerpc: Move get_auxv_entry() to harness.c

2015-04-11T10:49:20Z

Move get_auxv_entry() from pmu/lib.c up to harness.c in order to make it available to other tests. Signed-off-by: Sam Bobroff Signed-off-by: Michael Ellerman

selftests/powerpc: Add test for VPHN

2015-03-17T23:49:00Z

The goal is to verify vphn_unpack_associativity() parses VPHN numbers correctly. We feed it with a variety of input values and compare with expected results. PAPR+ does not say much about VPHN parsing: I came up with a list of tests that check many simple cases and some corner ones. I wouldn't dare to say the list is exhaustive though.
