CPPC(Collaborative Processor Performance Control)是ACPI规范中定义的一套机制,让OS根据CPU负载情况主动管理CPU的性能,OS与firmware通过共享内存机制通信,firmware收到消息后把请求性能转换为相应实际频率。其中firmware一般跑在单独的mcu。 ACPI _CPC对象方法 _CPC描述了怎么控制和监控性能的通用方法。 参数含义 Highest Pe...

最初的CPU性能扩展模块是基于AMD处理器上的传统内核通用ACPI cpufreq驱动,它对现代AMD平台的性能/功耗效率并不高。因此,这次活动是为了介绍一种新的AMD平台的CPU性能扩展设计,在Steam上使用VKD3D-Proton的3D游戏如Horizon Zero Dawn有更好的每瓦特性能扩展。
