NAME

       pmap_unwire — unwire a range of virtual pages

SYNOPSIS

       #include <sys/param.h>
       #include <vm/vm.h>
       #include <vm/pmap.h>

       void
       pmap_unwire(pmap_t pmap, vm_offset_t start, vm_offset_t end);

DESCRIPTION

       The function pmap_unwire() removes the wired attribute from each of the virtual-to-physical page mappings
       within  the virtual address range from start to end of the physical map pmap.  Every valid mapping within
       that range is required to have the wired attribute set.  Invalid mappings are ignored, since they  cannot
       have the wired attribute set.

NOTES

       Only  the  function  pmap_enter(9)  can  be used to set the wired attribute of a virtual-to-physical page
       mapping.
