Libcap2 provides a programming interface to POSIX capabilities on Linux-based operating systems.

libnetfilter_conntrack is a userspace library providing a programming interface (API) to the in-kernel connection tracking state table. The library libnetfilter_conntrack has been previously known as libnfnetlink_conntrack and libctnetlink. This library is currently used by conntrack-tools among many other applications.

Headers of the Linux-Libre kernel.

As a consequence of its monolithic design, file system code for Linux normally goes into the kernel itself---which is not only a robustness issue, but also an impediment to system extensibility. FUSE, for "file systems in user space", is a kernel module and user-space library that tries to address part of this problem by allowing users to run file system implementations as user-space processes.

The bbswitch module provides a way to toggle the Nvidia graphics card on Optimus laptops.

WirePlumber is a modular session / policy manager for PipeWire and a GObject-based high-level library that wraps PipeWire's API, providing convenience for writing the daemon's modules as well as external tools for managing PipeWire.

A *Free* project to implement OSF's RFC 86.0. Pluggable authentication modules are small shared object files that can be used through the PAM API to perform tasks, like authenticating a user at login. Local and dynamic reconfiguration are its key features.

This package provides utilities for testing, partitioning, etc of flash storage.

FBGrab is a framebuffer screenshot program that captures the Linux framebuffer and converts it to a PNG image. It can also convert a framebuffer dump file (copy) to a PNG image.

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.

This package provides the tuxedo_keyboard, tuxedo_io, clevo_wmi WMI and the clevo_acpi ACPI kernel modules to control the keyboard on most Tuxedo computers. The tuxedo_io module is also needed for the tuxedo-control-center (short tcc) package.

This package provides the statically-linked btrfs from the btrfs-progs package. It is meant to be used in initrds.

This package provides a kernel module that is capable of resetting hardware devices into a state where they can be re-initialized or passed through into a virtual machine (VFIO). While it would be great to have these in the kernel as PCI quirks, some of the reset procedures are very complex and would never be accepted as a quirk (ie AMD Vega 10).

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

This package provides the kexec program and ancillary utilities. Using kexec, it is possible to boot directly into a new kernel from the context of an already-running kernel, bypassing the normal system boot process.

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.

This package provides the documentation for the kernel Linux-Libre, as an Info manual. To consult it, run info linux.

rfkill is a simple tool for accessing the rfkill device interface, which is used to enable and disable wireless networking devices, typically WLAN, Bluetooth and mobile broadband.

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).

Kbd-neo provides the Neo2 keyboard layout for use with loadkeys(1) from kbd(4).

libnvme provides type definitions for NVMe specification structures, enumerations, and bit fields, helper functions to construct, dispatch, and decode commands and payloads, and utilities to connect, scan, and manage nvme devices on a Linux system.

EROFS is a compressed, read-only file system optimized for resource-scarce devices. This package provides user-space tools for creating EROFS file systems.

ddate displays the Discordian date and holidays of a given date. The Discordian calendar was made popular by the "Illuminatus!" trilogy by Robert Shea and Robert Anton Wilson.

cpupower is a set of user-space tools that use the cpufreq feature of the Linux kernel to retrieve and control processor features related to power saving, such as frequency and voltage scaling.
