Beignet only support CL_DEVICE_SVM_COARSE_GRAIN_BUFFER svm. Thanks, Yang Rong

I have checked that device capabilities has CL_DEVICE_SVM_FINE_GRAIN_BUFFER flag. Following code gives CL_INVALID_VALUE. Even removing CL_MEM_SVM_ATOMICS does not help. What could be wrong with the code? Additionally, how to the same SVM reservation by OpenCL C++ bindings (cl2.hpp)? size_t SVM_size = 42; void* p = clSVMAlloc ( context(), CL_MEM_READ_WRITE | CL_MEM_SVM_FINE_GRAIN_BUFFER | CL_MEM_SVM_ATOMICS, SVM_size, 0); cl_int err = clEnqueueSVMMap(queue(), CL_TRUE, CL_MAP_READ | CL_MAP_WRITE, p, SVM_size, 0, NULL, NULL); Thanks
