windows - 通过 WinAPI 确定英特尔高清显卡版本

Question

所以我想通过 WinAPI 函数获取有关显卡的信息，但有一个关于如何获取我的确切显卡信息的问题。我已经编写了调用 EnumDisplayDevices 的代码，并且通过调用我收到了 DeviceString“Intel(R) HD Graphics Family”。然而，这并没有告诉我确切的显卡，例如英特尔高清显卡系列有 4200、4400 等等(根据我的理解)。

我搜索了更多的方法来查找此信息，甚至查看了注册表，它仍然引导我找到“Intel(R) HD Graphics Family”的描述字符串......现在我在这里。非常感谢任何能帮助我的人，它实际上是一个 stackoverflow 线程，它首先将我引向了 EnumDisplayDevices 的方向 :)

Answer 1

我会使用 OpenGL 而不是 WinAPI 因为我不知道 WinAPI 是否有这样的功能并且懒得研究.是的，您可以在注册表项中搜索此信息，但由于可能会更改位置/名称，这在未来并不安全。 OpenGL 方法很简单:

1. 创建OpenGL渲染环境
2. 获取适当的供应商和设备字符串。
3. 发布OpenGL渲染环境

它适用于所有支持 OpenGL 1.0 的支持 OpenGL 的显卡/驱动程序，这些都是当今的显卡。

• 参见:C++ example of OpenGL context initialization
• 或:complete GL+VAO/VBO+GLSL+shaders example in C++

您可以使用 OpenGL 函数 glGetString 获取此信息:

GL_VENDOR Returns the company responsible for this OpenGL implementation. This name does not change from release to release.  
GL_RENDERER Returns the name of the renderer. This name is typically specific to a particular configuration of a hardware platform. It does not change from release to release.  
GL_VERSION Returns a version or release number (of supported OpenGL and gfx driver version)
GL_EXTENSIONS Returns a space-separated list of supported extensions to OpenGL (all capabilities of your card)

剩下的很简单(使用第二个链接中的 gl_init,gl_exit):

gl_init(Your_App_Window_Handle);
char *vendor =(char*)glGetString(GL_VENDOR);
char *device =(char*)glGetString(GL_RENDERER);
char *version=(char*)glGetString(GL_VERSION);
char *ext    =(char*)glGetString(GL_EXTENSIONS);
gl_exit();

我的设置返回:

[注释]

你只需要包括 gl.h 不需要 glu,glew 或其他任何东西(除了 wglext.h 应该单独包含在 gl.h 中)。它通常位于单独的包含子目录中，例如:

#include <gl\gl.h>

由于 Intel OpenGL 实现也没有公开版本，所以我只看到另一个选项。您需要获取卡的 PCI ID VID/PID 并与已知值进行交叉检查:

要获取 PCI ID，您可以使用:

• my setupapi.h C++ example

只需将解析字符串从 TEXT("USB") 更改为 TEXT("PCI") 并检查 VID 8086 设备这样:

bool PCIinfo()
    {
    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);
        s=szDesc; n=48; while (s.Length()<n) s+=" "; if (s.Length()>n) s=s.SubString(1,n); txt+=s+" ";
        SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_HARDWAREID,&dwPropertyRegDataType, (BYTE*)szDesc,sizeof(szDesc),&dwSize);
        s=szDesc; n=64; while (s.Length()<n) s+=" "; if (s.Length()>n) s=s.SubString(1,n); txt+=s+" ";
        SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_LOCATION_INFORMATION,&dwPropertyRegDataType, (BYTE*)szDesc,sizeof(szDesc),&dwSize);
        s=szDesc; n=40; while (s.Length()<n) s+=" "; if (s.Length()>n) s=s.SubString(1,n); txt+=s+" ";
        txt+="\r\n";
        }
    Main->mm_log->Lines->Add(txt);
    return true;
    }

该代码在我的设置中返回:
