selftests: timers: rtcpie: skip test if default RTC device does not exist

2021-06-08T01:18:52Z

This test will require /dev/rtc0, the default RTC device, or one specified by user to run. Since this default RTC is not guaranteed to exist on all of the devices, so check its existence first, otherwise skip this test with the kselftest skip code 4. Without this patch this test will fail like this on a s390x zVM: $ selftests: timers: rtcpie $ /dev/rtc0: No such file or directory not ok 1 selftests: timers: rtcpie # exit=22 With this patch: $ selftests: timers: rtcpie $ Default RTC /dev/rtc0 does not exist. Test Skipped! not ok 9 selftests: timers: rtcpie # SKIP Fixed up change log so "With this patch" text doesn't get dropped. Shuah Khan Signed-off-by: Po-Hsu Lin Signed-off-by: Shuah Khan

selftests/timers: Turn off timeout setting

2020-08-20T21:49:28Z

The following 4 tests in timers can take longer than the default 45 seconds that added in commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") to run: * nsleep-lat - 2m7.350s * set-timer-lat - 2m0.66s * inconsistency-check - 1m45.074s * raw_skew - 2m0.013s Thus they will be marked as failed with the current 45s setting: not ok 3 selftests: timers: nsleep-lat # TIMEOUT not ok 4 selftests: timers: set-timer-lat # TIMEOUT not ok 6 selftests: timers: inconsistency-check # TIMEOUT not ok 7 selftests: timers: raw_skew # TIMEOUT Disable the timeout setting for timers can make these tests finish properly: ok 3 selftests: timers: nsleep-lat ok 4 selftests: timers: set-timer-lat ok 6 selftests: timers: inconsistency-check ok 7 selftests: timers: raw_skew https://bugs.launchpad.net/bugs/1864626 Fixes: 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") Signed-off-by: Po-Hsu Lin Acked-by: John Stultz Signed-off-by: Shuah Khan

kselftests: timers: freq-step: Update maximum acceptable precision and errors

2019-06-22T09:28:53Z

PTI has a significant impact on precision of the MONOTONIC_RAW clock, which prevents a lot of computers from running the freq-step test. Increase the maximum acceptable precision for the test to not be skipped to 500 nanoseconds. After commit 78b98e3c5a66 ("timekeeping/ntp: Determine the multiplier directly from NTP tick length") the frequency and time errors should be much smaller. Reduce the maximum acceptable values for the test to pass to 0.02 ppm and 50 nanoseconds respectively.

selftests/timers: Add missing fflush(stdout) calls

2019-05-21T15:24:31Z

When running under a pipe, some timer tests would not report output in real-time because stdout flushes were missing after printf()s that lacked a newline. This adds them to restore real-time status output that humans can enjoy. Signed-off-by: Kees Cook Signed-off-by: Shuah Khan
