kernel/tools/testing/selftests/timers/Makefile, branch linux-4.1.y

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

2015-03-12T19:22:16Z

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.

selftests/timers: Add clocksource-switch test from timetest suite

2015-03-12T19:22:15Z

Adds the clocksource-switch tests which continually switches the current clocksource between all the available ones, watching for any timekeeping inconsistencies.

selftests/timers: Add skew_consistency test from the timetests suite

2015-03-12T19:22:15Z

This change adds the skew_consistency test, which twists the ADJ_FREQUENCY knob back and forth and watches for timekeeping inconsistencies. 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 change_skew test from timetest suite

2015-03-12T19:22:15Z

This patch adds the change_skew test which validates the adjtimex freq can be set to various values and then using the inconsistency-check, raw_skew, and nanosleep tests ensures time behaves properly.

selftests/timers: Add alarmtimer-suspend test from timetests suite

2015-03-12T19:22:14Z

This adds the alarmtimer-suspend test from the timetests suite, which tests that the alarmtimers wake the system up from suspend shortly after the time they were set to fire.
