348 Furthermore, uclamp lets userspace specify a minimum and a maximum utilization357 above. On top of that, uclamp is used to clamp the task utilization values,363 By using uclamp, userspace can e.g. allow a busy loop (100% utilization) to run364 on any CPU by giving it a low uclamp.max value. Conversely, it can force a small366 giving it a high uclamp.min value.
307 此外，uclamp允许用户空间指定任务的最小和最大利用率，要么以sched_setattr()的方式，要么以308 cgroup接口的方式（参阅Documentation/admin-guide/cgroup-v2.rst）。如其名字所暗示，uclamp314 CFS任务唤醒的CPU选择，遵循上面描述的算力适应性准则。在此之上，uclamp被用来限制任务利用率，320 通过使用uclamp，举例来说，用户空间可以允许忙等待循环（100%使用率）在任意CPU上运行，只要给321 它设置低的uclamp.max值。相反，uclamp能强制一个小的周期性任务（比如，10%利用率）在最高性能322 的CPU上运行，只要给它设置高的uclamp.min值。
