通过 WinAPI 确定 Intel HD 显卡版本 [英] Determine Intel HD Graphics Card Version Via WinAPI
问题描述
所以我试图通过 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.我编写了调用 EnumDisplayDevices 的代码，通过我的调用，我收到了 DeviceStringIntel(R) HD Graphics Family".然而，这并没有告诉我确切的卡，例如 Intel HD Graphics Family 有 4200、4400 等等(根据我的理解).
So I am trying to get information on graphics cards via WinAPI functions, but have a question regarding how to get my exact card information. I have written code to call EnumDisplayDevices and through my call I receive back the DeviceString "Intel(R) HD Graphics Family". However this is not telling me the exact card, for example the Intel HD Graphics Family has a 4200, 4400, so on (from my understanding).
我搜索了更多方法来查找此信息，甚至查看注册表，这仍然使我找到了Intel(R) HD Graphics Family"的描述字符串……现在我来了.非常感谢任何可以帮助我的人，实际上是一个 stackoverflow 线程，它首先引导我朝着 EnumDisplayDevices 的方向发展 :)
I searched around more for ways to find this information, even looking through the registry which still led me to a description string of "Intel(R) HD Graphics Family"... Now I am here. Thanks alot to anybody who can help me out, it was infact a stackoverflow thread which led me in the direction of EnumDisplayDevices in the first place :)
推荐答案
为此我会使用 OpenGL 代替 WinAPI，因为我不知道 WinAPI 甚至有一些这样的功能，懒得研究.是的，您可以搜索此信息的注册表项，但由于可能的位置/名称更改，这在将来是不安全的.OpenGL 方法很简单:
I would use OpenGL instead WinAPI for this because I do not know if WinAPI even has some feature like this and too lazy to research. Yes you can search registry keys for this info but that is not safe in the future due to possible location/name change. The OpenGL way is straight forward:
- 创建OpenGL渲染上下文
- 获取适当的供应商和设备字符串.
- 发布OpenGL渲染上下文
- create OpenGL rendering context
- obtain the appropriate vendor and device strings.
- release OpenGL rendering context
它适用于任何支持 OpenGL 1.0 的具有 OpenGL 功能的图形卡/驱动程序，这些都是当今的显卡.
It will work for any OpenGL capable graphic card/driver supporting OpenGL 1.0 which are all of the nowadays cards.
您可以使用 OpenGL 函数 glGetString 来获取此信息:
You can use OpenGL function glGetString to obtain this info:
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):
The rest is easy (using gl_init,gl_exit from second link):
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]
你只需要包含 gl.h 不需要 glu,glew 或其他任何东西(除了 wglext.h 应该被单独包含在 gl.h 中).它通常位于单独的包含子目录中，例如:
you need to include only gl.h for this no need for glu,glew or anything else (except wglext.h which should be included on its own inside gl.h). It is usually located in separate include subdirectory like:
#include <glgl.h>
由于英特尔 OpenGL 实现也没有公开版本，我只看到了另一种选择.您需要获取卡的 PCI ID VID/PID 并对照已知值进行交叉检查:
As Intel OpenGL implementation does not expose the version too I see only one other option. You need to acquire PCI ID VID/PID of the card and cross check against known values:
Model CPU arch. Release date PCI ID Execution units

要获取PCI ID，您可以使用:
只需将解析字符串从 TEXT("USB") 更改为 TEXT("PCI") 并检查 VID 8086 设备:
Just change the parsing string from TEXT("USB") to TEXT("PCI") and check VID 8086 devices so:
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+="
";
}
Main->mm_log->Lines->Add(txt);
return true;
}
该代码在我的设置中返回:

因此在不同的 IntelHD 图形计算机上运行它并检查是否存在不同的 PCI ID ...
so run it on different IntelHD graphics computers and check if different PCI ID is there ...
