不写代码怎么看某GPU是否支持OpenCL2.x的SVM？？？

[KayChanGeek]

const Device& device = devices[0];
        cl_device_svm_capabilities deviceCaps = 0;
        CV_Assert(((void)0, CL_DEVICE_SVM_CAPABILITIES == CL_DEVICE_SVM_CAPABILITIES_AMD)); // Check assumption
        cl_int status = clGetDeviceInfo((cl_device_id)device.ptr(), CL_DEVICE_SVM_CAPABILITIES, sizeof(deviceCaps), &deviceCaps, NULL);
        if (status != CL_SUCCESS)
        {
            CV_OPENCL_SVM_TRACE_ERROR_P("CL_DEVICE_SVM_CAPABILITIES via clGetDeviceInfo failed: %d\n", status);
            goto noSVM;
        }
        CV_OPENCL_SVM_TRACE_P("CL_DEVICE_SVM_CAPABILITIES returned: 0x%x\n", (int)deviceCaps);
        CV_Assert(((void)0, CL_DEVICE_SVM_COARSE_GRAIN_BUFFER == CL_DEVICE_SVM_COARSE_GRAIN_BUFFER_AMD)); // Check assumption
        svmCapabilities.value_ =
                ((deviceCaps & CL_DEVICE_SVM_COARSE_GRAIN_BUFFER) ? svm::SVMCapabilities::SVM_COARSE_GRAIN_BUFFER : 0) |
                ((deviceCaps & CL_DEVICE_SVM_FINE_GRAIN_BUFFER) ? svm::SVMCapabilities::SVM_FINE_GRAIN_BUFFER : 0) |
                ((deviceCaps & CL_DEVICE_SVM_FINE_GRAIN_SYSTEM) ? svm::SVMCapabilities::SVM_FINE_GRAIN_SYSTEM : 0) |
                ((deviceCaps & CL_DEVICE_SVM_ATOMICS) ? svm::SVMCapabilities::SVM_ATOMICS : 0);

以上代码可以看出某GPU是否支持SVM，支持的话支持哪种SVM类型！
我现在不想写代码，怎么看GPU有木有支持SVM，就是我要选型GPU，总不能买回来写个代码看一下支不支持吧，怎么看支不支持呢？看了GPU的配置参数，只有是否支持OPENCL，没有说是否支持SVM？？怎么看呢？
