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.

SEE ALSO
     pmap(9), pmap_enter(9), pmap_wired_count(9)
