Abstract: Systems and methods of cache flushing include receiving, from a software application, a first cache flush request to perform a range-based cache flush of a contiguous virtual address range within a virtual memory that maps to a physical memory. A single cache walk is triggered via a second cache flush request to a cache. The single cache walk performs the range-based cache flush for the contiguous physical address range from a beginning address of the contiguous physical address range to an ending address of the contiguous physical address range in response to the first cache flush request.
