Peter Bigot 057e4cbc5d tests: kernel: work_queue: remove unpassable tests The original implementation of resubmitting a delayed work item removed the item not only from the schedule, but also from the work queue if it was already in the work queue. This is not the semantics of the new implementation, which will leave the work item in the queue if the previous deadline had elapsed and the work item was submitted. The new semantics is preferred, as it improves consistency with SMP targets where once an item has been submitted to a queue it can be run at any time, and scheduling it again doesn't magically reverse the submission. The original test would never have passed on an SMP target, and passes now on qemu_x86 only because the timing granularity prevents the work item from being both scheduled and queued at the same time. The problematic test application is the one developed for the original implementation. Correct functioning of the new implementation is fully verified by the sibling work test. That the legacy API does not precisely preserve the original behavior where it was not consistent between SMP and uniprocessor targets is regrettable, but unavoidable. Remove the tests that cannot pass reliably. Also fix a missing reset() after a test. Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>		2021-03-10 06:10:59 -05:00

Title: Test workqeue APIs

Description:

A simple application verifying the workqueue API

--------------------------------------------------------------------------------

Building and Running Project:

This kernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
