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 functionpmap_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.
