tests/kernel: Add preemption priority test This test exaustively tests preemption points between threads of all priority classes (cooperative, preemptible, and metairq), done both from a synchronous reschedule (via k_sem_give() and from interrupt context (via irq_offload()), and with and without the sched_lock() held. It then detects the next thread that runs and validates vs. the documented priority rules. Note that there is a whitelisted case on ARM, where irq_offload() seems not to be working like a true interrupt (it always returns to the interrupted context and doesn't seem to hit the normal exception return path which can context switch). And native_posix is excluded because of failures and the fact that it's actually never possible to truly preempt a thread there (they run to completion inside _Swap() et. al. and then block themselves). Both of these should be fixable in the future but don't (seem to) directly relate to this test. Signed-off-by: Andy Ross <andrew.j.ross@intel.com> 2018-05-24 00:26:39 +08:00			`CONFIG_ZTEST=y`
