    NAME

     - copy physical memory pages
    
     
    

    SYNOPSIS

       #include <sys/param.h>
       #include <vm/vm.h>
       #include <vm/pmap.h>
    void Fo pmap_copy Fa pmap_t dst_pmap pmap_t src_pmap vm_offset_t dst_addr Fa vm_size_t len vm_offset_t src_addr Fc Ft void pmap_copy_page (vm_page_t src vm_page_t dst);
     

    DESCRIPTION

    The pmap_copy ();
    function copies the range specified by Fa src_addr and Fa len from the source physical map Fa src_pmap to the destination physical map Fa dst_pmap at the address Fa dst_addr .

    The pmap_copy_page ();
    function copies the physical page Fa src to the physical page Fa dst , by mapping the page into kernel virtual address space (KVA), and using bcopy ();
    to copy the page.  

    IMPLEMENTATION NOTES

    The pmap_copy ();
    routine is only advisory and need not do anything. Actually implementing it may seriously reduce system performance.

    The pmap_copy_page ();
    routine only operates upon a single page.
