Windows - CPU 电源管理 API [英] Windows - CPU power management APIs

问题描述

Windows 为 CPU 电源管理提供了哪些 API(我对 CPU 频率缩放、设置最小和最大 CPU 频率感兴趣 - 类似于您可以在电源计划中的控制面板中执行的操作，但以编程方式).我也对 .Net API 感兴趣.(这不是我打算在生产环境中使用的东西，而是作为一些动态电源管理算法的概念证明)

What APIs are provided by Windows for CPU power management (I'm interested in CPU frequency scaling, setting min and max CPU frequency - similar to what you can do in Control Panel in power plans, but in a programmatic way). I'm also interested in .Net APIs. (It is not something I intend to use in a production environment, but rather as a proof of concept for some dynamic power management algorithms)

推荐答案

.NET 电源管理 API 位于 Microsoft.Win32 命名空间中.

.NET Power Management APIs are in the Microsoft.Win32 namespace.

来自 http://msdn.microsoft.com/en-us 的示例/library/hxkc1kwd.aspx:

private void powerModeChanged(System.Object sender, Microsoft.Win32.PowerModeChangedEventArgs e)
{
    int si = SystemInformation.PowerStatus;
    switch (si)
    {
        case BatteryChargeStatus.Low:
            MessageBox.Show("Battery is running low", MessageBoxIcon.Exclamation);
        case BatteryChargeStatus.Low:
            MessageBox.Show("Battery is critically low", MessageBoxIcon.Stop);
        Default:
            // Battery is okay.
    }
}

通过在该命名空间中四处探索，您可以找到更多信息.

You can find lots more by poking around in that namespace.
