Abstract
Disclosed are various examples of providing efficient bit compression for direct mapping of physical memory addresses. In some examples, a hypervisor operating system component generates a mask of used address space bits indicated by memory map entries for a computing device. A longest range of unused address space bits is identified using the mask. The memory map entries are transformed to omit the longest range of unused address space bits.
