  • System and method for page table caching memory
    Patent number: 11550728
    Abstract: A processing system includes a processor, a memory, and an operating system that are used to allocate a page table caching memory object (PTCM) for a user of the processing system. An allocation of the PTCM is requested from a PTCM allocation system. In order to allocate the PTCM, a plurality of physical memory pages from a memory are allocated to store a PTCM page table that is associated with the PTCM. A lockable region of a cache is designated to hold a copy of the PTCM page table, after which the lockable region of the cache is subsequently locked. The PTCM page table is populated with page table entries associated with the PTCM and copied to the locked region of the cache.
