pmap - report memory map of a process SYNOPSIS
pmap [options] pid [...] DESCRIPTION
The pmap command reports the memory map of a process or processes. OPTIONS
-x, --extended Show the extended format. -d, --device Show the device format. -q, --quiet Do not display some header or footer lines. -A, --range low,high Limit results to the given range to low and high address range. Notice that the low and high arguments are single string separated with comma. -X Show even more details than the -x option. WARNING: format changes according to /proc/PID/smaps -XX Show everything the kernel provides -p, --show-path Show full path to files in the mapping column -c, --read-rc Read the default configuration -C, --read-rc-from file Read the configuration from file -n, --create-rc Create new default configuration -N, --create-rc-to file Create new configuration to file -h, --help Display help text and exit. -V, --version Display version information and exit. EXIT STATUS
0 Success. 1 Failure. 42 Did not find all processes asked for. SEE ALSO

pmap -- machine-dependent portion of virtual memory subsystem SYNOPSIS
#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; This header file may also define other data structures used by the pmap implementation. The header file <vm/pmap.h> defines a structure for tracking pmap statistics (see below). This structure is defined as: struct pmap_statistics { long resident_count; /* number of mapped pages */ long wired_count; /* number of wired pages */ }; The implementation's struct pmap must contain an instance of this structure having the name pm_stats, and it must be updated by the implemen- tation after each relevant pmap operation.
