Yes, might be two flavours, something like
rte_power_monitor() and rte_power_monitor_sync() 
or whatever would be a better name.

I thought about something very similar to cond_wait() working model:

/*
 * Caller has to obtain lock before calling that function.
 */
static inline int rte_power_monitor_sync(const volatile void *p,
                const uint64_t expected_value, const uint64_t value_mask,
                const uint32_t state, const uint64_t tsc_timestamp, rte_spinlock_t *lck)
{
	/* do whatever preparations are needed */
               ....
	umonitor(p);

	if (value_mask != 0 && *((const uint64_t *)p) & value_mask == expected_value) {
		return 0;
 	}
	
	/* release lock and go to sleep */
	rte_spinlock_unlock(lck);
	rflags = umwait();

	/* grab lock back after wakeup */
	rte_spinlock_lock(lck);

	/* do rest of processing */
	....
}

/* similar go cond_signal */
static inline void rte_power_monitor_wakeup(volatile void *p)
{
	uint64_t v;

	v = __atomic_load_n(p, __ATOMIC_RELAXED);
	__atomic_compare_exchange_n(p, v, &v, 1, __ATOMIC_RELAXED, __ATOMIC_RELAXED);
}               


Now in librte_power:

struct pmd_queue_cfg {
       /* to protect state and wait_addr */
       rte_spinlock_t lck;
       enum pmd_mgmt_state pwr_mgmt_state;
       void *wait_addr;
       /* rest fields */
      ....
} __rte_cache_aligned;


static uint16_t
rte_power_mgmt_umwait(uint16_t port_id, uint16_t qidx,
                struct rte_mbuf **pkts __rte_unused, uint16_t nb_rx,
                uint16_t max_pkts __rte_unused, void *_  __rte_unused)
{

        struct pmd_queue_cfg *q_conf;
        q_conf = &port_cfg[port_id].queue_cfg[qidx];

        if (unlikely(nb_rx == 0)) {
                q_conf->empty_poll_stats++;
                if (unlikely(q_conf->empty_poll_stats > EMPTYPOLL_MAX)) {
                        volatile void *target_addr;
                        uint64_t expected, mask;
                        uint16_t ret;
		
	         /* grab the lock and check the state */
                       rte_spinlock_lock(&q_conf->lck);
	         If (q-conf->state == ENABLED) {
	                        ret = rte_eth_get_wake_addr(port_id, qidx,
                                                    &target_addr, &expected, &mask);
		          If (ret == 0) {
			q_conf->wait_addr = target_addr;
			rte_power_monitor(target_addr, ..., &q_conf->lck);
		         }	
		          /* reset the wait_addr */
		          q_conf->wait_addr = NULL;
	         }
	         rte_spinlock_unlock(&q_conf->lck);	
	         ....
}

nt
rte_power_pmd_mgmt_queue_disable(unsigned int lcore_id,
                                uint16_t port_id,
                                uint16_t queue_id)
{
	...
	/* grab the lock and change the state */
               rte_spinlock_lock(&q_conf->lck);
	queue_cfg->state = DISABLED;

	/* wakeup if necessary */
	If (queue_cfg->wakeup_addr != NULL)
		rte_power_monitor_wakeup(queue_cfg->wakeup_addr);

	rte_spinlock_unlock(&q_conf->lck);
	...
}
