PMAP_UNWIRE(9) FreeBSD Kernel Developer's Manual PMAP_UNWIRE(9)
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.
