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).

SEE ALSO

     pmap(9), vm_map(9)
