Abstract: A method and an apparatus for a power assertion management are described. A power assertion indicator may be maintained for a device component having a power level. The power assertion indicator can indicate whether the power level of the device component is allowed to be lowered. A power assertion request may be sent from a first process to prevent lowering the power level of the device component before a data processing task is completed. A second process can receive a request from the first process to perform operations for the data processing task. The power level of the device component may not be allowed to be lowered before the second process completes the operations for the data processing task. The power level of the device component may be lowered after the data processing task is completed.

Abstract translation: 描述用于电源断言管理的方法和装置。 可以为具有功率电平的器件组件维持电源断言指示符。 电源断言指示灯可以指示设备组件的功率电平是否被允许降低。 可以从第一处理发送电源断言请求，以在数据处理任务完成之前防止降低设备组件的功率电平。 第二进程可以从第一进程接收对数据处理任务执行操作的请求。 在第二过程完成数据处理任务的操作之前，可能不允许降低设备组件的功率电平。 数据处理任务完成后，设备组件的功率级别可能会降低。
