Ztress // Bug with completion condition

[Dermiste]

Hi,

I am trying to get Ztress to work. Here is what I assumed given the documentation + we are running 3 threads using ZTRESS_EXECUTE macro:

• a THREAD will be marked as passed once both exec & preempt spec are met
• if passed, a THREAD will keep running until others are passed too
• an EXECUTION will complete & then stop all THREADs at the same time, once all are passed

What I experienced:

• a THREAD is marked as pass once either exec OR preempt spec is met
• once marked as passed, a THREAD stops executing
• an EXECUTION completes when no THREADs is running anymore

Hopefully I'm wrong in my understanding, but I don't get how one can get a overview of CPU load if THREADs stop executing one after another.

How to reproduce ? Execute the test located at tests\ztest\ztress, modify the ZTEST test_repeat_completion and instead of using repeat variable replace with weird values such as 1, 2 or 1000, also set preempt cnt, see below:

And results:

Any help much appreciated, I'm either super wrong in my understand on how to use Ztress or it does not work as expected.

Thanks in advance
