PVC platform with no support for atomic operations on system memory must always allocate buffers in local memory to avoid atomic access violation. Note: the feature is being implemented under the new registry key AllocateBuffersInLocalMemoryForMultiRootDeviceContexts (disabled by default) Related-To: NEO-7092 Signed-off-by: Milczarek, Slawomir <slawomir.milczarek@intel.com>
