过去几天我一直在尝试使用 C++ 获取 GPU 的温度
使用 NVAPI 我有以下代码
#include "stdafx.h"
#include "nvapi.h"
int _tmain(int argc, _TCHAR* argv[])
{
NvAPI_Status ret = NVAPI_OK;
int i=0;
NvDisplayHandle hDisplay_a[NVAPI_MAX_PHYSICAL_GPUS*2] = {0};
ret = NvAPI_Initialize();
if (!ret == NVAPI_OK){
NvAPI_ShortString string;
NvAPI_GetErrorMessage(ret, string);
printf("NVAPI NvAPI_Initialize: %s\n", string);
}
NvAPI_ShortString ver;
NvAPI_GetInterfaceVersionString(ver);
printf("NVAPI Version: %s\n", ver);
NvU32 cnt;
NvPhysicalGpuHandle phys;
ret = NvAPI_EnumPhysicalGPUs(&phys, &cnt);
if (!ret == NVAPI_OK){
NvAPI_ShortString string;
NvAPI_GetErrorMessage(ret, string);
printf("NVAPI NvAPI_EnumPhysicalGPUs: %s\n", string);
}
NvAPI_ShortString name;
NV_GPU_THERMAL_SETTINGS thermal;
ret = NvAPI_GPU_GetFullName(phys, name);
if (!ret == NVAPI_OK){
NvAPI_ShortString string;
NvAPI_GetErrorMessage(ret, string);
printf("NVAPI NvAPI_GPU_GetFullName: %s\n", string);
}
printf("Name: %s\n", name);
thermal.version =NV_GPU_THERMAL_SETTINGS_VER;
ret = NvAPI_GPU_GetThermalSettings(phys,0, &thermal);
if (!ret == NVAPI_OK){
NvAPI_ShortString string;
NvAPI_GetErrorMessage(ret, string);
printf("NVAPI NvAPI_GPU_GetThermalSettings: %s\n", string);
}
printf("Temp: %l C\n", thermal.sensor[0].currentTemp);
return 0;
}
我得到的输出是
NVAPI Version: NVidia Complete Version 1.10
Name: GeForce GTX 680
Temp: C
所以 NVAPI 正在初始化,它可以找到我的 GTX680 GPU,但它不会返回温度
