NAME

pmap_init, pmap_init2 — initialize the pmap subsystem

SYNOPSIS

#include <vm/vm.h>
#include <vm/pmap.h>

void

pmap_init(void);

void

pmap_init2(void);

DESCRIPTION

The pmap_init() function initializes the pmap(9) sub-system. It is called during system initialization by vm_init(), to initialize any structures that the pmap_init system needs in order to map between physical and virtual memory.

The pmap_init2() function initializes a zone for the PV entries. These are used to implement page sharing at the physical level. A high water mark is set so that the system can recover from excessive numbers of PV entries.
