selftests/timers: Cleanup Makefile to make it easier to add future tests Try to streamline the makefile so its easier to add timer/timekeeping tests. Also adds support for the CROSS_COMPILE variable.

kselftests: timers: Add test for frequency step This test checks the response of the system clock to frequency steps made with adjtimex(). The frequency error and stability of the CLOCK_MONOTONIC clock relative to the CLOCK_MONOTONIC_RAW clock is measured in two intervals following the step. The test fails if values from the second interval exceed specified limits.

selftests: add basic posix timers selftests Add some initial basic tests on a few posix timers interface such as setitimer() and timer_settime(). These simply check that expiration happens in a reasonable timeframe after expected elapsed clock time (user time, user + system time, real time, ...). This is helpful for finding basic breakages while hacking on this subsystem.

selftests: remove duplicated all and clean target 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.

Documentation, split up rtc.txt into documentation and test file This patch splits rtc.txt into two separate files, one for the documentation itself, and the other for the rtctest.c file. The rtctest file is moved into the kernel tools/testing/selftests/timers directory. This will make automated testing easier. Note that the only difference in the rtc.txt file is that the location of the rtctest.c file has changed.

timers, kselftest: Add 'adjtick' test to validate adjtimex() tick adjustments Recently a kernel side NTP bug was fixed via the following commit: 2619d7e9c92d ("time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of abs64()") When the bug was reported it was difficult to detect, except by tweaking the adjtimex tick value, and noticing how quickly the adjustment took: https://lkml.org/lkml/2015/9/1/488 Thus this patch introduces a new test which manipulates the adjtimex tick value and validates that the results are what we expect.
