It only contains (FEATURE_TESTS - FEATURE_DISPLAY) tests to display the rest of the checks on 'make VF=1'. But we can actually compute this list, which is less confusing.

The recent change to remove the vrX defines exposed the fact that we are building the copyloops tests without altivec enabled. It depends on the toolchain as to whether altivec is on by default or not, so it only breaks on some toolchains. But we should always enable it.

2015-03-16powerpc: Change vrX register defines to vX to match gcc and glibcAnton Blanchard1-33/+0
As our various loops (copy, string, crypto etc) get more complicated, we want to share implementations between userspace (eg glibc) and the kernel. We also want to write userspace test harnesses to put in tools/testing/selftest. One gratuitous difference between userspace and the kernel is the VMX register definitions - the kernel uses vrX whereas both gcc and glibc use vX. Change the kernel to match userspace.

2015-03-14selftests: Add install targetMichael Ellerman10-1/+73
This adds make install support to selftests. The basic usage is: $ cd tools/testing/selftests $ make install That installs into tools/testing/selftests/install, which can then be copied where ever necessary. The install destination is also configurable using eg: $ INSTALL_PATH=/mnt/selftests make install The implementation uses two targets in the child makefiles. The first "install" is expected to install all files into $(INSTALL_PATH). The second, "emit_tests", is expected to emit the test instructions (ie. bash script) on stdout. Separating this from install means the child makefiles need no knowledge of the location of the test script.

2015-03-14selftests: Introduce minimal shared logic for running testsMichael Ellerman29-67/+65
This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.

2015-03-12selftests/timers: Add set-2038 test from timetest suiteJohn Stultz2-1/+146
Adds the set-2038 test which sets the time to near-edge cases like the start and end of the 32 bit epoch and checks that time behaves properly. There is also a dangerous mode, which lets the clock roll over past 2038 on 32bit systems, which on some older kernels will cause system hangs.

2015-03-12perf hists browser: Fix UI bug after fold/unfoldHe Kuang1-0/+19
In perf hists browser, the fold/unfold stat of each hist entry is recorded but hb->nr_callchain_rows loses its value after zoom out and zoom in back. This causes a wrong row cursor range that restrict user to move down anymore. This bug can be reproduced as follows: $ perf record -g -e syscalls:* ls $ perf report Available samples ================================================================ 2 syscalls:sys_enter_mprotect <= [enter one of the entries] 2 syscalls:sys_exit_mprotect 13 syscalls:sys_enter_brk ...
