What is a PSS file?

A PSS file is a video file used by games for the PlayStation 2 console. It contains audio and video data and is used for playing in-game cutscenes and other movies. PSS files may be converted to more common video types, or split into separate audio and video files using several utilities.

NOTE: VLC media player only plays the video from PSS files, not the audio.

File Type 2 AutoCAD Plot Stamp Settings File

.PSS File Association 2

File used by AutoCAD, a 3D design drafting application; contains plot stamp information, such as the plot scale, paper size, layout name, and plotting device information; used for publishing and printing drawings using specified properties.

PSS files allow multiple users to access the same file and stamp their own plots using different settings.

.PSS File Association 4

A PSS file is a data file created by Adobe RoboHelp, a help content authoring application. It contains information about an .XPJ project in plain text, which includes the creation time of the project and language of the project. PSS files also store the locations of files referenced by the XPJ project, including .HHP HTML help project files .HHC HTML table of contents files, and .BRS browse sequence files.

PSS files are automatically created and overwritten by Adobe RoboHelp when creating and saving XPJ project files. PSS files should not be added to version, or source, control since it causes problems in the XPJ project.

Adobe RoboHelp is a program used for publishing help, policy, and knowledge base content. XPJ files are created to store projects that are used for developing help manuals and knowledge bases for software applications.

What does pss mean in /proc/pid/smaps

I was confused about the Pss column in /proc/pid/smaps , so I wrote a program to test it:

Here I found Pss equal to Private_Dirty , but I wonder why.

BTW: Is there any detailed documentation for smaps ?

1 Answer 1

The «proportional set size» (PSS) of a process is the count of pages it has in memory, where each page is divided by the number of processes sharing it. So if a process has 1000 pages all to itself, and 1000 shared with one other process, its PSS will be 1500

The /proc/PID/smaps is an extension based on maps, showing the memory consumption for each of the process’s mappings. For each of mappings there is a series of lines such as the following:

The first of these lines shows the same information as is displayed for the mapping in /proc/PID/maps. The remaining lines show the size of the mapping (size), the amount of the mapping that is currently resident in RAM (RSS), the process’ proportional share of this mapping (PSS), the number of clean and dirty private pages in the mapping. Note that even a page which is part of a MAP_SHARED mapping, but has only a single pte mapped, i.e. is currently used by only one process, is accounted as private and not as shared. «Referenced» indicates the amount of memory currently marked as referenced or accessed. «Anonymous» shows the amount of memory that does not belong to any file. Even a mapping associated with a file may contain anonymous pages: when MAP_PRIVATE and a page is modified, the file page is replaced by a private anonymous copy. «Swap» shows how much would-be-anonymous memory is also used, but out on swap.

This Question on Unix and Linux Stackexchange covers almost the topic. See Mat’s excellent answer which will surely clear all your doubts.
