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.
