Control groups is Linux kernel method for process resource restriction, permission handling and more. This package provides userspace interface to this kernel feature.

perf is a tool suite for profiling using hardware performance counters, with support in the Linux kernel. perf can instrument CPU performance counters, tracepoints, kprobes, and uprobes (dynamic tracing). It is capable of lightweight profiling. This package contains the user-land tools and in particular the perf command.

The EVDI is a Linux kernel module that enables management of multiple screens, allowing user-space programs to take control over what happens with the image. It is essentially a virtual display for which applications using the libevdi library can add, remove, and receive screen updates.

The EVDI driver uses the standard Linux DRM. Its displays can be controlled by standard tools such as xrandr and display settings applets in graphical environments.

libnetfilter_acct is the userspace library providing interface to extended accounting infrastructure.

1. creating accounting objects

2. retrieving accounting objects (and atomically set to zero)

3. deleting accounting objects

For the nfnetlink_acct subsystem.

acpi attempts to replicate the functionality of the "old" apm command on ACPI systems, including battery and thermal information. It does not support ACPI suspending, only displays information about ACPI devices.

acpilight is a backward-compatibile replacement for xbacklight that uses the ACPI interface to set the display brightness. On modern laptops acpilight can control both display and keyboard backlight uniformly on either X11, the console or Wayland.

snapscreenshot saves a screenshot of one or more Linux text consoles as a Targa (.tga) image. It can be used by anyone with read access to the relevant /dev/vcs* file(s).

The USB/IP protocol enables to pass USB device from a server to a client over the network. The server is a machine which shares an USB device and the client is a machine which uses USB device provided by a server over the network. The USB device may be either physical device connected to a server or software entity created on a server using USB gadget subsystem. The usbip-utils are userspace tools to used to handle connection and management on both side. The client needs the vhci-hcd Linux kernel module and the server needs the usbip_host Linux kernel module.

OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric communication services to applications. OFI is best described as a collection of libraries and applications used to export fabric services. The key components of OFI are: application interfaces, provider libraries, kernel services, daemons, and test applications.

Libfabric is a core component of OFI. It is the library that defines and exports the user-space API of OFI, and is typically the only software that applications deal with directly. It works in conjunction with provider libraries, which are often integrated directly into libfabric.

The inih (INI Not Invented Here) library is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and name: value entries.

Kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.

These tools are designed on top of libkmod, a library that is shipped with kmod. The aim is to be compatible with tools, configurations and indices from the module-init-tools project.

fbcat saves the contents of the Linux framebuffer (/dev/fb*), or a dump thereof. It supports a wide range of drivers and pixel formats.

fbcat can take screenshots of virtually any application that can be made to write its output to the framebuffer, including (but not limited to) text-mode or graphical applications that don't use a display server.

Also included is fbgrab, a wrapper around fbcat that emulates the behaviour of Gunnar Monell's older fbgrab utility.

psmisc is a set of small utilities that use the proc file system.

• fuser identifies processes using files or sockets;

• killall kills processes by name;

• prtstat prints statistics of a process;

• pslog prints the log file(s) of a process;

• pstree shows the currently running processes as a tree;

• peekfd shows the data travelling over a file descriptor.

libnetfilter_cthelper is a userspace library that provides a programming interface to user-space connection tracking helpers.

1. register new user-space connection tracking helpers

2. unregister user-space connection tracking helpers

3. list existing registered user-space connection tracking helpers

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs. Configuration options and patches have been applied for use with MNT/Reform systems.

This package provides a Linux kernel module that will provide a serial device /dev/ttyebus with almost no latency upon receiving. It is dedicated to the PL011 UART of the Raspberry Pi.

GameMode is a daemon and library for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process. GameMode was designed primarily as a stop-gap solution to problems with the Intel and AMD CPU powersave or ondemand governors, but is now host to a range of optimisation features and configurations, including CPU governor, I/O priority, process niceness, kernel scheduler, screensaver inhibiting, GPU performance mode, and custom scripts.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

The libiec61883 library provides a higher level API for streaming DV, MPEG-2 and audio over Linux IEEE 1394.

Udev is a daemon which dynamically creates and removes device nodes from /dev/, handles hotplug events and loads drivers at boot time.

This package provides a way to record and replay device descriptions and events, making it possible to emulate input devices through the Linux kernel's input system. Emulated devices are for most practical purposes indistinguishable from real devices.

It provides a command line program and also a Python library.

This package provides means to to read BitLocker encrypted partitions. Write functionality is also provided but check the README.

This package provides the following binaries to drive the Linux Device Mapper multipathing driver:

1. multipath - Device mapper target autoconfig.

2. multipathd - Multipath daemon.

3. mpathpersist - Manages SCSI persistent reservations on dm multipath devices.

4. kpartx - Create device maps from partition tables.
