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.
