NAME¶
pmap — machine-dependent portion of virtual memory subsystemSYNOPSIS¶
#include <sys/param.h>#include <vm/vm.h>
#include <vm/pmap.h>
DESCRIPTION¶
The pmap module is the machine-dependent portion of the FreeBSD VM (Virtual Memory) sub-system. Each function documented herein must have its own architecture-dependent implementation. The pmap module is responsible for managing hardware-dependent objects such as page tables, address maps, TLBs, etc. Machine-dependent code must provide the header file <machine/pmap.h>. This file contains the definition of the pmap structure:struct pmap { /* Contents defined by pmap implementation. */ }; typedef struct pmap *pmap_t;
struct pmap_statistics { long resident_count; /* number of mapped pages */ long wired_count; /* number of wired pages */ };
