+---------------
+
+The CPUfreq governor "interactive" is designed for low latency,
+interactive workloads. This governor sets the CPU speed depending on
+usage, similar to "ondemand" and "conservative" governors. However
+there is no polling, or 'sample_rate' required to scale the CPU up.
+
+Sampling CPU load every X ms can lead to under powering the CPU
+for X ms, leading to dropped framerate, stuttering UI etc..
+
+Scaling the CPU up is done when coming out of idle, and like "ondemand"
+scaling up will always go to MAX, then step down based off of cpu load.
+
+There is only one tuneable value for this governor:
+
+min_sample_time: The ammount of time the CPU must spend (in uS)
+at the current frequency before scaling DOWN. This is done to
+more accurately determine the cpu workload and the best speed for that
+workload. The default is 50ms.
