如何获取特定设备使用的内存范围与WMI（Windows Management Instrumentation） [英] How to get memory range used by a specific device with WMI (Windows Management Instrumentation)

问题描述

如何获取特定设备（特别是内存范围）所使用的资源，知道其名称和/或DeviceID和/或Pci总线编号，设备编号和功能编号？
例如，我想知道英特尔AHCI控制器使用的内存范围。使用查询SELECT * FROM Win32_IDEController WHERE Name LIKE\％ahci％\我可以得到一些信息，如完整的名称，设备ID和其他信息。然后我认为使用完整的名称或设备ID，我可以使用类Win32_DeviceMemoryAddress选择设备使用的内存范围。然而，这个类没有任何有用的属性，我可以设置来获得与AHCI控制器相关的内存范围。

How can I get the resources used by a specific device (in particular, the memory range) of a specific device knowing it's name and/or DeviceID and/or the Pci bus number, Device number and function number? For example, I want to know what memory range an Intel AHCI Controller uses. With the query "SELECT * FROM Win32_IDEController WHERE Name LIKE\"%ahci%\"" I can get some info like the complete name, device id, and other informations. Then I thought that using the complete name or device id I could select the memory range used by the device using the class "Win32_DeviceMemoryAddress". However, this class does not have any useful attributes that I can set to get the memory range associated with the AHCI controller. Name, Caption and description all return a string with the starting address and ending address.

提前感谢。

不知道如何使用 WMI ，但在此链接，在获取设备资源下，作者声称 CM_Get_Next_Res_Des 提供此信息。到那里，虽然，不是简单的...这正是我想要完成的，现在...将有助于进一步的细节，当我到那里...

Don't know how to do it with WMI, but in this link, under "Get Device Resource", the author claims that CM_Get_Next_Res_Des provides this information. Getting there, though, is not simple... that's exactly what I'm trying to accomplish right now... will contribute further details when I get there...
