PMAP_PINIT(9) BSD Kernel Developer's Manual PMAP_PINIT(9)NAME
pmap_pinit, pmap_pinit0 -- initialize pmap structures
SYNOPSIS
#include <sys/param.h>
#include <vm/vm.h>
#include <vm/pmap.h>
void
pmap_pinit(pmap_t pmap);
void
pmap_pinit0(pmap_t pm);
DESCRIPTION
The pmap_pinit() function initializes the preallocated and zeroed structure pmap, such as one in a vmspace structure.
The pmap_pinit0() function initializes the physical map pm, associated with process 0, the first process created in the system.
IMPLEMENTATION NOTES
The pmap_pinit2() function has been deprecated, and should be implemented as a stub until further notice.

PMAP_OBJECT_INIT_PT(9) BSD Kernel Developer's Manual PMAP_OBJECT_INIT_PT(9)NAME
pmap_object_init_pt -- initialize page tables for a VM object
SYNOPSIS
#include <sys/param.h>
#include <vm/vm.h>
#include <vm/pmap.h>
void
pmap_object_init_pt(pmap_t pmap, vm_offset_t addr, vm_object_t object, vm_pindex_t pindex, vm_size_t size, int limit);
DESCRIPTION
The pmap_object_init_pt() function preloads the page table entries into the specified physical map pmap, for the given object at the virtual
address addr, for size bytes, beginning at the page index pindex within the object. The map bits limit are heeded when creating the mapping.
IMPLEMENTATION NOTES
This function is not strictly required by an architecture's pmap(9) implementation, but it does provide performance benefits if implemented.
It is intended to eliminate the blast of soft faults on process startup, and immediately following a call to mmap(2).
