Abstract: Examples described herein relate to a computing system supporting custom page sized ranges for an application to map contiguous memory regions instead of many smaller sized pages. An application can request a custom range size. An operating system can allocate a contiguous physical memory region to a virtual address range by specifying a custom range sizes that are larger or smaller than the normal general page sizes. Virtual-to-physical address translation can occur using an address range circuitry and translation lookaside buffer in parallel. The address range circuitry can determine if a custom entry is available to use to identify a physical address translation for the virtual address. Physical address translation can be performed by transforming the virtual address in some examples.
