Description:
|
|
This file provides pre-summed memory information for a
|
|
process. The format is almost identical to /proc/pid/smaps,
|
|
except instead of an entry for each VMA in a process,
|
|
smaps_rollup has a single entry (tagged "[rollup]")
|
|
for which each field is the sum of the corresponding
|
|
fields from all the maps in /proc/pid/smaps.
|
|
Additionally, the fields Pss_Anon, Pss_File and Pss_Shmem
|
|
are not present in /proc/pid/smaps. These fields represent
|
|
the sum of the Pss field of each type (anon, file, shmem).
|
|
For more details, see Documentation/filesystems/proc.rst
|
|
and the procfs man page.
|
|
|
|
Typical output looks like this:
|
|
|
|
00100000-ff709000 ---p 00000000 00:00 0 [rollup]
