tests: kernel: add tickless test Added test cases to verify tickless idle concepts defined in https://www.zephyrproject.org/doc/subsystems/power_management.html#tickless-idle Test points: verify system clock recovery after exiting tickless idle; verify slicing scheduler behaves as expected Jira: ZEP-339 Change-Id: Ic0a86d725e9692aa217375cedc7396372a026a88 Signed-off-by: Sharron LIU <sharron.liu@intel.com> 2017-04-14 12:55:02 +02:00			`CONFIG_ZTEST=y`

tests/kernel/tickless/tickless_concept: Force 100 Hz ticks This test was written to assume ~100 Hz ticks in ways that are difficult to fix. It wants to sleep for periods on the order of the TICKLESS_IDLE_THRESH kconfig, which is extremely small on high tick rate systems and (on nRF in particular) does not have a cleanly divisible representation in milliseconds. Fixing precision issues by cranking the idle threshold up on a per-system basis seems like an abuse, as that is what we want to be testing in the first place. Just let the test run at the tick rate it has always expected. Signed-off-by: Andy Ross <andrew.j.ross@intel.com> 2019-06-16 05:43:28 +02:00			`CONFIG_SYS_CLOCK_TICKS_PER_SEC=100`
tests: Never disable SMP Disabling SMP mode for certain tests was a one-release thing, done to avoid having to triage every test independently (MANY are not SMP-safe), and with the knowledge that it was probably hiding bugs in the kernel. Turn it on pervasively. Tests are treated with a combination of flagging specific cases as "1cpu" where we have short-running tests that can be independently run in an otherwise SMP environment, and via setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still runs the full SMP kernel config, but with only one CPU available).
