selftests: timers: Convert nsleep-lat test to generate KTAP output

2023-10-05T21:00:14+00:00

Currently the nsleep-lat test does not produce KTAP output but rather a custom format. This means that we only get a pass/fail for the suite, not for each individual test that the suite does. Convert to using the standard kselftest output functions which result in KTAP output being generated. Signed-off-by: Mark Brown Signed-off-by: Shuah Khan

selftests: timers: Convert posix_timers test to generate KTAP output

2023-10-05T21:00:07+00:00

Currently the posix_timers test does not produce KTAP output but rather a custom format. This means that we only get a pass/fail for the suite, not for each individual test that the suite does. Convert to using the standard kselftest output functions which result in KTAP output being generated. As part of this fix the printing of diagnostics in the unlikely event that the pthread APIs fail, these were using perror() but the API functions directly return an error code instead of setting errno.

tools: timers: fix freq average calculation

2023-07-13T19:32:36+00:00

Delete a duplicate assignment from this function implementation. The note means ppm is average of the two actual freq samples. But ppm have a duplicate assignment. Signed-off-by: Minjie Du Acked-by: John Stultz Signed-off-by: Shuah Khan

selftests/timers/posix_timers: Test delivery of signals across threads

2023-04-16T07:00:18+00:00

Test that POSIX timers using CLOCK_PROCESS_CPUTIME_ID eventually deliver a signal to all running threads. This effectively tests that the kernel doesn't prefer any one thread (or subset of threads) for signal delivery.

selftests: timers: clocksource-switch: adapt to kselftest framework

2022-07-14T20:36:52+00:00

So we have proper counters at the end of a test. We also print the kselftest header at the end of the test, so we don't mix with the output of the child process. There is only this one test anyhow. Signed-off-by: Wolfram Sang Acked-by: John Stultz Signed-off-by: Shuah Khan

selftests: timers: clocksource-switch: add 'runtime' command line parameter

2022-07-14T20:36:42+00:00

So the user can decide how long the test should run. Signed-off-by: Wolfram Sang Acked-by: John Stultz Signed-off-by: Shuah Khan

selftests: timers: clocksource-switch: add command line switch to skip sanity check

2022-07-14T20:36:34+00:00

The sanity check takes a while. If you do repeated checks when debugging, this is time consuming. Add a parameter to skip it. Signed-off-by: Wolfram Sang Acked-by: John Stultz Signed-off-by: Shuah Khan

selftests: timers: clocksource-switch: sort includes

2022-07-14T20:36:29+00:00

It is easier to check if you need to add an include if the existing ones are sorted. Signed-off-by: Wolfram Sang Acked-by: John Stultz Signed-off-by: Shuah Khan

selftests: timers: clocksource-switch: fix passing errors from child

2022-07-14T20:36:24+00:00

The return value from system() is a waitpid-style integer. Do not return it directly because with the implicit masking in exit() it will always return 0. Access it with appropriate macros to really pass on errors.

selftests: timers: inconsistency-check: adapt to kselftest framework

2022-07-14T20:36:18+00:00
