The interactive governor aims to be\nsignificantly more responsive to ramp CPU quickly up when CPU-intensive\nactivity begins.\n\nExisting governors sample CPU load at a particular rate, typically\nevery X ms. This can lead to under-powering UI threads for the period of\ntime during which the user begins interacting with a previously-idle system\nuntil the next sample period happens.\n\nThe \u0027interactive\u0027 governor uses a different approach. Instead of sampling\nthe CPU at a specified rate, the governor will check whether to scale the\nCPU frequency up soon after coming out of idle. When the CPU comes out of\nidle, a timer is configured to fire within 1-2 ticks. If the CPU is very\nbusy from exiting idle to when the timer fires then we assume the CPU is\nunderpowered and ramp to MAX speed.\n\nIf the CPU was not sufficiently busy to immediately ramp to MAX speed, then\nthe governor evaluates the CPU load since the last speed adjustment,\nchoosing the highest value between that longer-term load or the short-term\nload since idle exit to determine the CPU speed to ramp to.\n\nA realtime thread is used for scaling up, giving the remaining tasks the\nCPU performance benefit, unlike existing governors which are more likely to\nschedule rampup work to occur after your performance starved tasks have\ncompleted.\n\nThe tuneables for this governor are:\n/sys/devices/system/cpu/cpufreq/interactive/min_sample_time:\n\tThe minimum amount of time to spend at the current frequency before\n\tramping down. This is to ensure that the governor has seen enough\n\thistoric CPU load data to determine the appropriate workload.\n\tDefault is 80000 uS.\n/sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load\n\tThe CPU load at which to ramp to max speed.
