NAME

pmap_init pmap_init2 - initialize the pmap subsystem

SYNOPSIS

In sys/param.h In vm/vm.h In vm/pmap.h Ft void Fn pmap_init void Ft void Fn pmap_init2 void

DESCRIPTION

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

The Fn 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.
