git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Larger virtual address space on 64-bit server CPUs. By default we use a 128TB virtual address space, but a process can request access to the full 512TB by passing a hint to mmap(). - Support for the new Power9 "XIVE" interrupt controller. - TLB flushing optimisations for the radix MMU on Power9. - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface Architecture 2.0". - The ability to configure the mmap randomisation limits at build and runtime. - Several small fixes and cleanups to the kprobes code, as well as support for KPROBES_ON_FTRACE. - Major improvements to handling of system reset interrupts, correctly treating them as NMIs, giving them a dedicated stack and using a new hypervisor call to trigger them, all of which should aid debugging and robustness. - Many fixes and other minor enhancements.

2017-03-27selftests/powerpc: Fix standalone powerpc buildMichael Ellerman1-5/+5
The changes to enable building with a separate output directory, in commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT") broke building the powerpc selftests on their own, eg: $ cd tools/testing/selftests/powerpc; make It was partially fixed in commit e53aff45c490 ("selftests: lib.mk Fix individual test builds"), which defined OUTPUT for standalone tests. But that only defines OUTPUT within the Makefile, the value is not exported so sub-shells can't see it. We could export OUTPUT, but it's actually cleaner to just expand the value of OUTPUT before we invoke the shell.

2017-03-20selftests/powerpc: Add cache_shape sniff testMichael Ellerman4-0/+137
This is a very basic test of the new cache shape AUXV entries. All it does at the moment is look for the entries and error out if we don't find all the ones we expect. Primarily intended for folks bringing up a new chip to check that the cache info is making it all the way to userspace correctly. Signed-off-by: Michael Ellerman <[email protected]>

2017-03-09selftests/powerpc: Replace stxvx and lxvx with stxvd2x/lxvd2xCyril Bur1-24/+24
On POWER8 (ISA 2.07) lxvx and stxvx are defined to be extended mnemonics of lxvd2x and stxvd2x. For POWER9 (ISA 3.0) the HW architects in their infinite wisdom made lxvx and stxvx instructions in their own right. POWER9 aware GCC will use the POWER9 instruction for lxvx and stxvx causing these selftests to fail on POWER8. Further compounding the issue, because of the way -mvsx works it will cause the power9 instructions to be used regardless of -mcpu=power8 to GCC or -mpower8 to AS. The safest way to address the problem for now is to not use the extended mnemonic. We don't care how the CPU loads the values from memory since the tests only performs register comparisons, so using stdvd2x/lxvd2x does not impact the test.

2017-02-14selftests/powerpc: Fix remaining fallout from recent changesMichael Ellerman4-12/+13
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.

2017-01-05selftests: remove duplicated all and clean target[email protected]15-111/+46
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.

2016-11-14selftests/powerpc: Return false instead of -1 in require_paranoia_below()Peter Senna Tschudin1-3/+3
Returning a negative value for a boolean function seem to have the undesired effect of returning true. require_paranoia_below() is a boolean function, but the variable used to store the return value is an integer, receiving -1 or 0. This patch converts rc to bool, replaces -1 by false, and 0 by true. mpe: This wasn't exhibiting in practice because the common case, where we do the comparison of the desired level vs the current value, was being compiled into a computation based on the result of the comparison, ie. it wasn't using the default -1 value at all. However that was just luck and the code is still wrong.
