I am trying to use wglGetGPUInfoAMD and wglGetGPUIDsAMD and I crash out when accessing these functions. This is under 10.9 and a Radeon 5870... I use GLEW 1.5.6 to setup the OpenGL extensions... using freeglut 2.6.
GLuint gpuIDs[16] = {0};
GLuint maxGpus = wglGetGPUIDsAMD(16, gpuIDs);
GLint freeMem[4] = {0};
glGetIntegerv(GL_TEXTURE_FREE_MEMORY_ATI, &freeMem[0]);
availableMemory = freeMem[0] / 1024;
if(wglGetGPUInfoAMD(gpuIDs[0], WGL_GPU_RAM_AMD, GL_UNSIGNED_INT, sizeof(GLuint), &totalMemory) == -1)
{
errorLog << "Error on ATI GPU Info Query for GPU RAM!" << std::endl;
totalMemory = 0;
}
if(wglGetGPUInfoAMD(gpuIDs[0], WGL_GPU_CLOCK_AMD, GL_UNSIGNED_INT, sizeof(GLuint), &clockSpeed) != 1)
{
errorLog << "Error on ATI GPU Info Query for GPU speed!" << std::endl;
clockSpeed = 0;
}
Thanks
