description For efficient reclamation of pre-allocated direct memory access (DMA) memory in a computing environment, hot-add random access memory (RAM) is emulated for a general purpose use by reclamation of pre-allocated DMA memory reserved at boot time by notifying a non-kernel use device user that the non-kernel use device has a smaller window, stopping and remapping to the smaller window, and notifying a kernel that new memory has been added, wherein the new memory is a region left after the remap. The hot-add RAM is split into at least two continuous parts.
