详细的 PCI-E 信息，Windows答案

【问题标题】：Detailed PCI-E information, Windows详细的 PCI-E 信息，Windows
【发布时间】：2017-12-16 19:43:25
【问题描述】：

我有一个项目，我需要从带有图形卡的计算机收集信息，从 1 到 12，它有。然后将这些信息保存在云中以供以后使用。

我最需要的是：

它是什么 GPU 多少内存它正在使用哪个 PCI 插槽，1、2、3 等（或任何名称）

Windows WMI 似乎有一些信息，我一直在查看不同的类，但似乎很难找到 PCI-E 插槽。有谁知道如何获取这些信息？

【问题讨论】：

为什么投反对票？是的，OP 不包含他当前尝试的任何代码，但我觉得这仍然是相关的问题。在我看来，对没有任何 cmet 更改/修复或至少有什么问题的低代表用户投反对票是没有用的。

【解决方案1】：

您应该寻找 PCI 插槽我在字符串中没有看到任何 PCI-E 定义（并不意味着没有）。如果我只尝试"PCI"，结果会枚举 PCI 和 PCI-E 设备。在 BDS2006 C++/VCL 中，我使用 this（我前段时间失败了）只是通过更改匹配字符串：

    {
    int i,n;
    AnsiString s,txt="";
    DWORD dwSize,dwPropertyRegDataType;
    HDEVINFO hDevInfo;
    SP_DEVINFO_DATA DeviceInfoData;
    TCHAR szDesc[1024];

//  hDevInfo = SetupDiGetClassDevs(NULL, NULL, NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES);           // List all devices
//  hDevInfo = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES);    // List all connected USB devices
    hDevInfo = SetupDiGetClassDevs(NULL, TEXT("PCI"), NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES);    // List all connected PCI devices
    if (hDevInfo == INVALID_HANDLE_VALUE) return false;
    // Find the ones that are driverless
    for (i=0;;i++)
        {
        DeviceInfoData.cbSize = sizeof(DeviceInfoData);
        if (!SetupDiEnumDeviceInfo(hDevInfo, i, &DeviceInfoData)) break;
        SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_DEVICEDESC,&dwPropertyRegDataType, (BYTE*)szDesc,sizeof(szDesc),&dwSize);

忽略 VCL 的东西。重要的是USBinfo() 函数（是的，我用它来获取USB 信息）。它将枚举与您初始化它的字符串匹配的所有设备（如在设备管理器中）（其中 3 条类似的行 2 已被删除）。请明确AnsiString 是字符串类（从[1] 而不是[0] 访问元素）并且DWORD 是无符号的32 位整数。 Main->mm_log 就是我输出结果的TMemo。不要忘记包含setupapi.h

但是，当您收集 GPU 信息时，您可能还想尝试 OpenGL 方法：

Determine Intel HD Graphics Card Version Via WinAPI

您可以收集支持的扩展和功能列表，还可以获取特定的 GPU 信息，例如管道数量、纹理单元，甚至还有一些可用内存...
