pmap_init, pmap_init2 — initialize the pmap subsystem
#include <sys/param.h> #include <vm/vm.h> #include <vm/pmap.h> void pmap_init(void); void pmap_init2(void);
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.
