2015-04-03ftracetest: Do not use usleep directlyNamhyung Kim3-6/+33
The usleep is only provided on distros from Redhat so running ftracetest on other distro resulted in failures due to the missing usleep. The reason of using [u]sleep in the test was to generate (scheduler) events. It can be done various ways like this: yield() { ping localhost -c 1 || sleep .001 || usleep 1 || sleep 1; } For more information to the history of this patch, please refer to: Link: http://lkml.kernel.org/r/[email protected] Reported-by: Michael Ellerman <[email protected]> Reported-by: Dave Jones <[email protected]> Reported-by: Luis Henriques <[email protected]> Suggested-by: Pádraig Brady <[email protected]> Acked-by: Steven Rostedt <[email protected]> Acked-by: Masami Hiramatsu <[email protected]> Signed-off-by: Namhyung Kim <[email protected]> Signed-off-by: Shuah Khan <[email protected]>

The set-timer-lat test fails when testing CLOCK_BOOTTIME_ALARM or CLOCK_REALTIME_ALARM when the user isn't running as root or with CAP_WAKE_ALARM.

2015-03-28selftests/powerpc: Add a test of the switch_endian() syscallMichael Ellerman6-1/+214
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 <[email protected]>

2015-03-24tools, update rtctest.c to verify passage of timePrarit Bhargava1-0/+13
rtctest.c checks to see if PIE is functioning by testing if 20 interrupts occur at rates from 2HZ to 64HZ. While this check is good, it does not check to see if the correct amount of time has actually passed. This misses situations where the RTC may be operating at a higher or lower frequency than expected. This patch introduces a simple check to verify if the time passed is less than 10% of what was programmed into the RTC.

The bulk of the selftests are actually below the powerpc sub directory. This adds support for installing them, when on a powerpc machine, or if ARCH and CROSS_COMPILE are set appropriately. This is a little more complicated because of the sub directory structure under powerpc, but much of the common logic in lib.mk is still used. The net effect of the patch is still a reduction in code.

2015-03-19selftests: Fix build failures when invoked from kselftest targetShuah Khan1-0/+8
Several tests that rely on implicit build rules fail to build, when invoked from the main Makefile kselftest target. These failures are due to --no-builtin-rules and --no-builtin-variables options set in the inherited MAKEFLAGS. --no-builtin-rules eliminates the use of built-in implicit rules and --no-builtin-variables is for not defining built-in variables. These two options override the use of implicit rules resulting in build failures. In addition, inherited LDFLAGS result in build failures and there is no need to define LDFLAGS. Clear LDFLAGS and MAKEFLAG when make is invoked from the main Makefile kselftest target. Fixing this at selftests Makefile avoids changing the main Makefile and keeps this change self contained at selftests level.

2015-03-17selftests/powerpc: Build the copyloops with -maltivecMichael Ellerman1-0/+1
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.

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.

2015-03-13selftests: 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.

2015-03-13selftests: 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.

This commit sets CONFIG_RCU_TORTURE_TEST_SLOW_INIT=y, but leaves the default time zero. This can be overridden by passing the "--bootargs rcutree.gp_init_delay=1" argument to kvm.sh. Signed-off-by: Paul E. McKenney <[email protected]>
