selftests: remove CROSS_COMPILE in dedicated Makefile

2017-01-05T20:42:11Z

After previous clean up patches, memfd and timers could get CROSS_COMPILE from tools/testing/selftest/lib.mk. There is no need to preserve these definition. So, this patch remove them. Acked-by: Michael Ellerman Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

selftests: remove duplicated all and clean target

2017-01-05T20:41:35Z

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. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

kselftests: timers: Add set-tz test case

2016-06-02T22:39:56Z

Mika Westerberg reported a erroneous change in the error checking of settimeofday, so I wanted to add a test to ensure we don't trip over this again.

timers, kselftest: Add 'adjtick' test to validate adjtimex() tick adjustments

2015-10-12T07:51:34Z

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.

Documentation, split up rtc.txt into documentation and test file

2015-03-25T04:01:58Z

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.

selftests/timers: Use shared logic to run and install tests

2015-03-19T18:03:58Z

Change the timers Makefile to make use of shared run and install logic in lib.mk. Destructive tests are installed but not run by default. Add a new variable, TEST_PROGS_EXTENDED, which is a list of extra programs to install, but which are not run by the default run_tests logic. Signed-off-by: Michael Ellerman Signed-off-by: Shuah Khan

selftests/timers: Add set-2038 test from timetest suite

2015-03-12T19:22:16Z

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.

selftests/timers: Add set-tai from the timetest suite

This patch adds the set-tai test which ensures the tai offset can be set properly from adjtimex. Cc: Shuah Khan Cc: Prarit Bhargava Cc: Thomas Gleixner Cc: Richard Cochran Signed-off-by: John Stultz Tested-by: Prarit Bhargava Signed-off-by: Shuah Khan

selftests/timers: Add leapcrash test from the timetest suite

2015-03-12T19:22:16Z

This change adds the leapcrash test which tests to see if a leapsecond deadlock which was observed from 2.6.26 to 3.3 is present on this system.

selftests/timers: Add leap-a-day test from timetest suite

2015-03-12T19:22:16Z

This change adds the leap-a-day test which sets STA_INS and STA_DEL each day to trigger leapseconds each day. It also has a mode to jump the time to right before the end of the day each iteration.
