          Be aware that not all cpufreq drivers support the conservative
          governor. If unsure have a look at the help section of the
          driver. Fallback governor will be the performance governor.

+         Use the CPUFreq governor 'interactive' as default. This allows
+         you to get a full dynamic cpu frequency capable system by simply
+         loading your cpufreq low-level hardware driver, using the
+         'interactive' governor for latency-sensitive workloads. Fallback
+         governor will be the performance governor.

+         'interactive' - This driver adds a dynamic cpufreq policy governor
+         designed for latency-sensitive workloads.
+
+         This governor attempts to reduce the latency of clock
+         increases so that the system is more responsive to
+         interactive workloads.
+
+         To compile this driver as a module, choose M here: the
+         module will be called cpufreq_interactive.
