 Abstract
 ~~~~~~~~
 
-Existing power management mechanisms require developers
-to change application design or change code to make use of it.
-The PMD power management API provides a convenient alternative
-by utilizing Ethernet PMD RX callbacks,
-and triggering power saving whenever empty poll count reaches a certain number.
-
-Monitor
-   This power saving scheme will put the CPU into optimized power state
-   and use the ``rte_power_monitor()`` function
-   to monitor the Ethernet PMD RX descriptor address,
-   and wake the CPU up whenever there's new traffic.
-
-Pause
-   This power saving scheme will avoid busy polling
-   by either entering power-optimized sleep state
-   with ``rte_power_pause()`` function,
-   or, if it's not available, use ``rte_pause()``.
-
-Frequency scaling
-   This power saving scheme will use ``librte_power`` library
-   functionality to scale the core frequency up/down
-   depending on traffic volume.
-
-.. note::
-
-   Currently, this power management API is limited to mandatory mapping
-   of 1 queue to 1 core (multiple queues are supported,
-   but they must be polled from different cores).
+Existing power management mechanisms require developers to change application
+design or change code to make use of it. The PMD power management API provides a
+convenient alternative by utilizing Ethernet PMD RX callbacks, and triggering
+power saving whenever empty poll count reaches a certain number.
+
+* Monitor
+   This power saving scheme will put the CPU into optimized power state and
+   monitor the Ethernet PMD RX descriptor address, waking the CPU up whenever
+   there's new traffic. Support for this scheme may not be available on all
+   platforms, and further limitations may apply (see below).
+
+* Pause
+   This power saving scheme will avoid busy polling by either entering
+   power-optimized sleep state with ``rte_power_pause()`` function, or, if it's
+   not supported by the underlying platform, use ``rte_pause()``.
+
+* Frequency scaling
+   This power saving scheme will use ``librte_power`` library functionality to
+   scale the core frequency up/down depending on traffic volume.
+
+The "monitor" mode is only supported in the following configurations and scenarios:
+
+* If ``rte_cpu_get_intrinsics_support()`` function indicates that
+  ``rte_power_monitor()`` is supported by the platform, then monitoring will be
+  limited to a mapping of 1 core 1 queue (thus, each Rx queue will have to be
+  monitored from a different lcore).
+
+* If ``rte_cpu_get_intrinsics_support()`` function indicates that the
+  ``rte_power_monitor()`` function is not supported, then monitor mode will not
+  be supported.
+
+* Not all Ethernet drivers support monitoring, even if the underlying
+  platform may support the necessary CPU instructions. Please refer to
+  :doc:`../nics/overview` for more information.
