Techniques for adaptive device power management are described. A hardware computing unit detects a launch of an operating system (OS) of an application to be executed on the hardware computing unit. The hardware computing unit identifies a launched application and determines whether there is a hardware profile associated with the application. The hardware profile includes one or more hardware parameters that produce optimal performance for power consumption of the hardware computing unit when the launched application is executed. Based on determining that the hardware profile is present, a power policy of the OS is updated for the launched application, and a driver updates a power state of the hardware computing unit based on the new power policy. 描述了用于自适应设备功率管理的技术。硬件计算单元检测操作系统(OS)对待在该硬件计算单元上执行的应用程序的启动。该硬件计算单元识别启动的应用程序并且确定是否存在与该应用程序相关联的硬件配置文件。该硬件配置文件包括一个或多个硬件参数，当执行该启动的应用程序时，该一个或多个硬件参数针对该硬件计算单元的功率消耗产生最佳性能。基于确定该硬件配置文件存在，针对该启动的应用程序更新该OS的功率策略，并且驱动程序基于新功率策略来更新该硬件计算单元的功率状态。
