    Low mem vs High mem


    As per my understanding, lowmem is the memory where we have a one to one mapping with virtual to physical memory. Page tables are used in highmem to make the user apps to feel that it has more physical memory.

    User apps will only use highmem? is there any possibility to use lowmem as well?

    My perception was that only non-movable pages are allocated from lowmem in most of the cases.

    Please correct me if I was wrong in understanding.

    Thanks & Regards,
