+
+2.7 Hotplug
+-----------
+
+The CPUfreq governor "hotplug" operates similary to "ondemand" and
+"conservative". It's decisions are based primarily on CPU load. Like
+"ondemand" the "hotplug" governor will ramp up to the highest frequency
+once the run-time tunable "up_threshold" parameter is crossed. Like
+"conservative", the "hotplug" governor exports a "down_threshold"
+parameter that is also tunable at run-time. When the "down_threshold"
+is crossed the CPU transitions to the next lowest frequency in the
+CPUfreq frequency table instead of decrementing the frequency based on a
+percentage of maximum load.
+
+The main reason "hotplug" governor exists is for architectures requiring
+that only the master CPU be online in order to hit low-power states
+(C-states). OMAP4 is one such example of this. The "hotplug" governor
+is also helpful in reducing thermal output in devices with tight thermal
+constraints.
+
+Auxillary CPUs are onlined/offline based on CPU load, but the decision
+to do so is made after averaging several sampling windows. This is to
+reduce CPU hotplug "thrashing", which can be caused by normal system
+entropy and leads to lots of spurious plug-in and plug-out transitions.
+The number of sampling periods averaged together is tunable via the
+"hotplug_in_sampling_periods" and "hotplug_out_sampling_periods"
+run-time tunable parameters.
