DESCRIPTION¶
Thepmap_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.
