345 Furthermore, uclamp lets userspace specify a minimum and a maximum utilization354 above. On top of that, uclamp is used to clamp the task utilization values,360 By using uclamp, userspace can e.g. allow a busy loop (100% utilization) to run361 on any CPU by giving it a low uclamp.max value. Conversely, it can force a small363 giving it a high uclamp.min value.
