.Dd July 17, 2014 .Dt PMAP_UNWIRE 9 .Os .Sh NAME .Nm pmap_unwire .Nd unwire a range of virtual pages .Sh SYNOPSIS n sys/param.h n vm/vm.h n vm/pmap.h .Ft void .Fo pmap_unwire .Fa "pmap_t pmap" "vm_offset_t start" "vm_offset_t end" .Fc .Sh DESCRIPTION
p The function .Fn pmap_unwire removes the wired attribute from each of the virtual-to-physical page mappings within the virtual address range from .Fa start to .Fa end of the physical map .Fa 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. .Sh NOTES Only the function .Xr pmap_enter 9 can be used to set the wired attribute of a virtual-to-physical page mapping. .Sh SEE ALSO .Xr pmap 9 , .Xr pmap_enter 9 , .Xr pmap_wired_count 9 .Sh AUTHORS This manual page was written by .An Alan L.
