22 The pmap utility prints information about the address space of a
23 process.
24
26 The following options are supported:
27 -a Prints anonymous and swap reservations for shared
29 mappings.
30 -A address_range Specifies the subrange of address space to display.
33 address_range is specified in one of the following
34 forms:
35 start_addr
37 A single address limits the output to the seg‐
39 ment (or the page if the -L option is present)
40 containing that address. If the specified
41 address corresponds to the starting address of
42 a segment, the output always includes the whole
43 segment even when the -L option is specified.
44 start_addr,
47 An address followed by comma without the end
49 address limits the output to all segments (or
50 pages if the -L option is present) starting
51 from the one containing the specified address.
52 start_addr,end_addr
55 An address range specified by the start address
57 and end addresses limits the output to all seg‐
58 ments (or pages if the -L option is present)
59 starting from the segment or page containing
60 the start address through the segment or page
61 containing the end address.
62 ,end_addr
65 An address range started with comma without the
67 start address limits the output to all segments
68 (or pages if the -L option is present) starting
69 from the first one present until the segment
70 (or page if the -L option is present) contain‐
71 ing the specified address.
72 -F Force. Grabs the target process even if another
76 process has control.
77 See USAGE.
79 -l Shows unresolved dynamic linker map names.
82 -L Prints lgroup containing physical memory that backs
85 virtual memory.
86 -r Prints the process's reserved addresses.
89 -s Prints HAT page size information.
92 -S Displays swap reservation information per mapping.
95 See USAGE for more information.
96 -x Displays additional information per mapping. See
99 USAGE for more information.

103 The pmap utility prints information about the address space of a
104 process.
105 Process Mappings
107 /usr/bin/pmap [ -rslF ] [-A address_range] [ pid | core ] ...
110 By default, pmap displays all of the mappings in the virtual
113 address order they are mapped into the process. The mapping size,
114 flags, and mapped object name are shown.
115 The -A option can be used to limit the output to a specified
117 address range. The specified addresses are rounded up or down to a
118 segment boundary and the output includes the segments bounded by
119 those addresses.
120 Process Lgroup Mappings
123 /usr/bin/pmap -L [ -rslF ] [-A address_range] pid ...
126 The -L option can be used to determine the lgroup containing the
129 physical memory backing the specified virtual memory. When used
130 with the -A option, the specified addresses are rounded up or down
131 to a page boundary and the output is limited to the page or pages
132 bounded by those addresses.
133 This can be used in conjunction with plgrp(1) to discover whether
135 the home lgroup of a thread of interest is the same as where the
136 memory is located and whether there should be memory locality for
137 the thread. The lgrpinfo(1) command can also be useful with this
138 pmap option. It displays the lgroup hierarchy, contents, and char‐
139 acteristics which gives more information about the lgroups that the
140 memory is distributed across and their relationship to each other
141 and any other lgroups of interest.
142 In addition, the thread and memory placement can be changed by
144 using plgrp(1), pmadvise(1), or madv.so.1(1).
145 Process anon/locked mapping details
148 /usr/bin/pmap -x [ -aslF ] [-A address_range] [ pid | core ] ...
151 The -x option displays additional information per mapping. The size
154 of each mapping, the amount of resident physical memory (RSS), the
155 amount of anonymous memory, and the amount of memory locked is
156 shown with this option. This does not include anonymous memory
157 taken by kernel address space due to this process.
158 Swap Reservations
161 /usr/bin/pmap -S [ -alF ] [-A address_range] [ pid | core ] ...
164 The -S option displays swap reservation information per mapping.
167 Caution should be exercised when using the -F flag. Imposing two con‐
171 trolling processes on one victim process can lead to chaos. Safety is
172 assured only if the primary controlling process, typically a debugger,
173 has stopped the victim process and the primary controlling process is
174 doing nothing at the moment of application of the proc tool in ques‐
175 tion.
176
178 One line of output is printed for each mapping within the process,
179 unless the --s or --L option is specified. With -s option, one line is
180 printed for a contiguous mapping of each hardware translation page
181 size. With -L option one line is printed for a contiguous mapping
182 belonging to the same lgroup. With both -L and -s options, one line is
183 printed for a contiguous mapping of each hardware translation page size
184 belonging to the same lgroup. The column headings are shown in paren‐
185 theses below.
186 Virtual Address (Address)
188 The first column of output represents the starting virtual address
190 of each mapping. Virtual addresses are displayed in ascending
191 order.
192 Virtual Mapping Size (Kbytes)
195 The virtual size in kilobytes of each mapping.
197 Resident Physical Memory (RSS)
200 The amount of physical memory in kilobytes that is resident for
202 each mapping, including that which is shared with other address
203 spaces.
204 Anonymous Memory (Anon)
207 The number of pages, counted by using the system page size, of
209 anonymous memory associated with the specified mapping. Anonymous
210 memory shared with other address spaces is not included, unless the
211 -a option is specified.
212 Anonymous memory is reported for the process heap, stack, for 'copy
214 on write' pages with mappings mapped with MAP_PRIVATE (see
215 mmap(2)).
216 Locked (Locked)
219 The number of pages locked within the mapping. Typical examples are
221 memory locked with mlock() and System V shared memory created with
222 SHM_SHARE_MMU.
223 Permissions/Flags (Mode)
226 The virtual memory permissions are shown for each mapping. Valid
228 permissions are:
229 r: The mapping can be read by the process.
231 w: The mapping can be written by the process.
234 x: Instructions that reside within the mapping can be executed
237 by the process.
238 Flags showing additional information for each mapping can be dis‐
240 played:
241 s: The mapping is shared such that changes made in the observed
243 address space are committed to the mapped file, and are visi‐
244 ble from all other processes sharing the mapping.
245 R: Swap space is not reserved for this mapping. Mappings created
248 with MAP_NORESERVE and System V ISM shared memory mappings do
249 not reserve swap space.
250 *: The data for the mapping is not present in the core file
253 (only applicable when applied to a core file). See core‐
254 adm(1M) for information on configuring core file content.
255 Lgroup (Lgrp)
259 The lgroup containing the physical memory that backs the specified
261 mapping.
262 Mapping Name (Mapped File)
265 A descriptive name for each mapping. The following major types of
267 names are displayed for mappings:
268 o A mapped file: For mappings between a process and a
270 file, the pmap command attempts to resolve the file name
271 for each mapping. If the file name cannot be resolved,
272 pmap displays the major and minor number of the device
273 containing the file, and the file system inode number of
274 the file.
275 o Anonymous memory: Memory not relating to any named
277 object or file within the file system is reported as [
278 anon ].
279 The pmap command displays common names for certain known
281 anonymous memory mappings:
282 [ heap ] The mapping is the process heap.
285 [ stack ] The mapping is the main stack.
288 [ stack tid=n ] The mapping is the stack for
291 thread n.
292 [ altstack tid=n ] The mapping is used as the alter‐
295 nate signal stack for thread n.
296 If the common name for the mapping is unknown, pmap displays [
299 anon ] as the mapping name.
300 o System V Shared Memory: Mappings created using System V
302 shared memory system calls are reported with the names
303 shown below:
304 shmid=n: The mapping is a System V shared memory
307 mapping. The shared memory identifier
308 that the mapping was created with is
309 reported.
310 ism shmid=n: The mapping is an "Intimate Shared Mem‐
313 ory" variant of System V shared memory.
314 ISM mappings are created with the
315 SHM_SHARE_MMU flag set, in accordance
316 with shmat(2) (see shmop(2)).
317 dism shmid=n: The mapping is a pageable variant of
320 ISM. Pageable ISM is created with the
321 SHM_PAGEABLE flag set in accordance
322 with shmat(2) (see shmop(2)).
323 o Other: Mappings of other objects, including devices such
327 as frame buffers. No mapping name is shown for other
328 mapped objects.
329 Page Size (Pgsz)
332 The page size in kilobytes that is used for hardware address trans‐
334 lation for this mapping. See memcntl(2) for further information.
335 Swap Space (Swap)
338 The amount of swap space in kilobytes that is reserved for this
340 mapping. That is, swap space that is deducted from the total avail‐
341 able pool of reservable swap space that is displayed with the com‐
342 mand swap -s. See swap(1M).
343
346 Example 1 Displaying Process Mappings
347 By default, pmap prints one line for each mapping within the address
350 space of the target process. The following example displays the address
351 space of a typical bourne shell:

379 Example 2 Displaying Memory Allocation and Mapping Types
383 The -x option can be used to provide information about the memory allo‐
386 cation and mapping types per mapping. The amount of resident, non-
387 shared anonymous, and locked memory is shown for each mapping:
388 example$ pmap -x 102908

410 The amount of incremental memory used by each additional instance of a
415 process can be estimated by using the resident and anonymous memory
416 counts of each mapping.
417 In the above example, the bourne shell has a resident memory size of
421 1032Kbytes. However, a large amount of the physical memory used by the
422 shell is shared with other instances of shell. Another identical
423 instance of the shell shares physical memory with the other shell where
424 possible, and allocate anonymous memory for any non-shared portion. In
425 the above example, each additional bourne shell uses approximately
426 56Kbytes of additional physical memory.
427 A more complex example shows the output format for a process containing
431 different mapping types. In this example, the mappings are as follows:
432 0001000: Executable text, mapped from 'maps' program
435 0002000: Executable data, mapped from 'maps' program
437 0002200: Program heap
439 0300000: A mapped file, mapped MAP_SHARED
442 0400000: A mapped file, mapped MAP_PRIVATE
443 0500000: A mapped file, mapped MAP_PRIVATE | MAP_NORESERVE
445 0600000: Anonymous memory, created by mapping /dev/zero
447 0700000: Anonymous memory, created by mapping /dev/zero
449 with MAP_NORESERVE
450 0800000: A DISM shared memory mapping, created with SHM_PAGEABLE
452 with 8MB locked via mlock(2)
453 0900000: A DISM shared memory mapping, created with SHM_PAGEABLE,
455 with 4MB of its pages touched.
456 0A00000: A DISM shared memory mapping, created with SHM_PAGEABLE,
458 with none of its pages touched.
459 0B00000: An ISM shared memory mapping, created with SHM_SHARE_MMU

489 Example 3 Displaying Page Size Information
493 The -s option can be used to display the hardware translation page
496 sizes for each portion of the address space. (See memcntl(2) for futher
497 information on Solaris multiple page size support).
498 In the example below, we can see that the majority of the mappings are
502 using an 8K-Byte page size, while the heap is using a 4M-Byte page
503 size.
504 Notice that non-contiguous regions of resident pages of the same page
508 size are reported as separate mappings. In the example below, the
509 libc.so library is reported as separate mappings, since only some of
510 the libc.so text is resident:

548 Example 4 Displaying Swap Reservations
552 The -S option can be used to describe the swap reservations for a
555 process. The amount of swap space reserved is displayed for each map‐
556 ping within the process. Swap reservations are reported as zero for
557 shared mappings, since they are accounted for only once system wide.

585 The swap reservation information can be used to estimate the amount of
590 virtual swap used by each additional process. Each process consumes
