*
*
* Allocates a shared virtual memory buffer (referred to as a SVM buffer) that can be shared by the host and all devices in an OpenCL context that support
* shared virtual memory.
*
* If {@link #CL_MEM_SVM_FINE_GRAIN_BUFFER MEM_SVM_FINE_GRAIN_BUFFER} is not specified, the buffer can be created as a coarse grained SVM allocation. Similarly, if
* {@link #CL_MEM_SVM_ATOMICS MEM_SVM_ATOMICS} is not specified, the buffer can be created without support for the OpenCL 2.0 SVM atomic operations.
*
* Calling {@code SVMAlloc} does not itself provide consistency for the shared memory region. When the host can't use the SVM atomic operations, it must
* rely on OpenCL's guaranteed memory consistency at synchronization points. To initialize a buffer to be shared with a kernel, the host can create the
* buffer and use the resulting virtual memory pointer to initialize the buffer's contents.
*
* For SVM to be used efficiently, the host and any devices sharing a buffer containing virtual memory pointers should have the same endianness. If the
* context passed to {@code SVMAlloc} has devices with mixed endianness and the OpenCL implementation is unable to implement SVM because of that mixed
* endianness, {@code SVMAlloc} will fail and return {@code NULL}.
*
* Although SVM is generally not supported for image objects, {@link CL12#clCreateImage CreateImage} may create an image from a buffer (a 1D image from a buffer
* or a 2D image from buffer) if the buffer specified in its image description parameter is a SVM buffer. Such images have a linear memory representation
* so their memory can be shared using SVM. However, fine grained sharing and atomics are not supported for image reads and writes in a kernel.
*
* If {@link CL10#clCreateBuffer CreateBuffer} is called with a pointer returned by {@code SVMAlloc} as its {@code host_ptr} argument, and
* {@link CL10#CL_MEM_USE_HOST_PTR MEM_USE_HOST_PTR} is set in its {@code flags} argument, {@code CreateBuffer} will succeed and return a valid non-zero buffer object as
* long as the {@code size} argument to {@code CreateBuffer} is no larger than the {@code size} argument passed in the original {@code SVMAlloc} call. The
* new buffer object returned has the shared memory as the underlying storage. Locations in the buffer's underlying shared memory can be operated on using,
* e.g., atomic operations if the device supports them.
*
* @param context a valid OpenCL context used to create the SVM buffer
* @param flags a bit-field that is used to specify allocation and usage information. One of:
{@link CL10#CL_MEM_READ_WRITE MEM_READ_WRITE} {@link CL10#CL_MEM_WRITE_ONLY MEM_WRITE_ONLY} {@link CL10#CL_MEM_READ_ONLY MEM_READ_ONLY} {@link #CL_MEM_SVM_FINE_GRAIN_BUFFER MEM_SVM_FINE_GRAIN_BUFFER} {@link #CL_MEM_SVM_ATOMICS MEM_SVM_ATOMICS}
* @param size the size in bytes of the SVM buffer to be allocated
* @param alignment the minimum alignment in bytes that is required for the newly created buffer's memory region. It must be a power of two up to the largest data type
* supported by the OpenCL device. For the full profile, the largest data type is {@code long16}. For the embedded profile, it is {@code long16} if the
* device supports 64-bit integers; otherwise it is {@code int16}. If alignment is {@code 0}, a default alignment will be used that is equal to the
* size of largest data type supported by the OpenCL implementation.
*
* @return a valid non-{@code NULL} shared virtual memory address if the SVM buffer is successfully allocated. Otherwise, like {@code malloc}, it returns a {@code NULL} pointer
* value. {@code SVMAlloc} will fail if:
*
*
* - {@code context} is not a valid context.
* - {@code flags} does not contain {@link #CL_MEM_SVM_FINE_GRAIN_BUFFER MEM_SVM_FINE_GRAIN_BUFFER} but does contain {@link #CL_MEM_SVM_ATOMICS MEM_SVM_ATOMICS}.
* - Values specified in {@code flags} do not follow rules for supported values.
* - {@link #CL_MEM_SVM_FINE_GRAIN_BUFFER MEM_SVM_FINE_GRAIN_BUFFER} or {@link #CL_MEM_SVM_ATOMICS MEM_SVM_ATOMICS} is specified in flags and these are not supported by at least one device in context.
* - The values specified in {@code flags} are not valid.
* - {@code size} is {@code 0} or > {@link CL10#CL_DEVICE_MAX_MEM_ALLOC_SIZE DEVICE_MAX_MEM_ALLOC_SIZE} value for any device in context.
