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).
