PMAP_REMOVE(9) FreeBSD Kernel Developer's Manual PMAP_REMOVE(9)
NAME
pmap_remove, pmap_remove_all, pmap_remove_pages - remove pages from a
physical map
SYNOPSIS
#include <sys/param.h>
#include <vm/vm.h>
#include <vm/pmap.h>
void
pmap_remove(pmap_t pmap, vm_offset_t sva, vm_offset_t eva);
void
pmap_remove_all(vm_page_t m);
void
pmap_remove_pages(pmap_t pmap);
DESCRIPTION
The pmap_remove() function removes the range of addresses between sva and
eva from the physical map pmap. If eva is less than sva, then the result
is undefined. It is assumed that both sva and eva are page-aligned
addresses.
The pmap_remove_all() removes the physical page m from all physical maps
in which it resides, and reflects back the modify bits to the appropriate
pager.
The pmap_remove_pages() function removes all user pages from the physical
map pmap. This function is called when a process exits to run down its
address space more quickly than would be the case for calling
pmap_remove().
