// This QP port to Zephyr assumes that Active Objects will use only the
// preemptive Zephyr priorities [0..(CONFIG_NUM_PREEMPT_PRIORITIES - 1U)].
// In this priority numbering, the QP AO priority QF_MAX_ACTIVE (highest)
// maps to Zephyr priority 0 (highest). The QP AO priority 1 (lowest) maps
// to Zephyr priority (CONFIG_NUM_PREEMPT_PRIORITIES - 2U).
//
// NOTE2:
// Zephyr does not support selective scheduler locking up to a given
// priority ceiling. Therefore, this port uses global Zephyr scheduler lock.
