/*
|
|
* Test backported deletion behavior by creating tasks of various affinities and
|
|
* check if the task memory is freed immediately under the correct conditions.
|
|
*
|
|
* The behavior of vTaskDelete() has been backported form FreeRTOS v9.0.0. This
|
|
* results in the immediate freeing of task memory and the immediate execution
|
|
* of deletion callbacks under the following conditions...
|
|
* - When deleting a task that is not currently running on either core
|
|
* - When deleting a task that is pinned to the same core (with respect to
|
|
* the core that calls vTaskDelete()
|
|
*
|
|
* If the two conditions are not met, freeing of task memory and execution of
|
|
* deletion callbacks will still be carried out by the Idle Task.
