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.

This Linux module creates virtual video devices. V4L2 applications will treat these as ordinary video devices but read video data generated by another application, instead of a hardware device such as a capture card.

This lets you apply nifty effects to your Jitsi video, for example, but also allows some more serious things like adding streaming capabilities to an application by hooking GStreamer into the loopback device.

This package contains utilities for accessing the powercap Linux kernel feature through sysfs. It includes an implementation for working with Intel RAPL. It provides the commands powercap-info and powercap-set.

Interception Tools provides a composable infrastructure on top of libudev and libevdev. The following utilities are provided:

• udevmon --- monitor input devices for launching tasks

• intercept --- redirect device input events to stdout

• uinput --- redirect device input events from stding to virtual device

• mux --- mux streams of input events

Iproute2 is a collection of utilities for controlling TCP/IP networking and traffic with the Linux kernel. The most important of these are ip, which configures IPv4 and IPv6, and tc for traffic control.

Most network configuration manuals still refer to ifconfig and route as the primary network configuration tools, but ifconfig is known to behave inadequately in modern network environments, and both should be deprecated.

FuseISO is a FUSE module to mount ISO file system images (.iso, .nrg, .bin, .mdf and .img files). It supports plain ISO9660 Level 1 and 2, Rock Ridge, Joliet, and zisofs.

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

Touchégg is an application that runs in the background and transform the gestures you make on your touchpad or touchscreen into visible actions in your desktop.

Procenv is a command-line tool that displays as much detail about itself and its environment as possible. It can be used as a test tool, to understand the type of environment a process runs in, and for comparing system environments.

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

PowerTOP is a Linux tool to diagnose issues with power consumption and power management. In addition to being a diagnostic tool, PowerTOP also has an interactive mode where the user can experiment various power management settings for cases where the operating system has not enabled these settings.

The reform2_lpc module allows for interaction with the NXP LPC11U24 Cortex-M0 MCU system controller in the Reform 2 open hardware laptop. It provides battery status information and is necessary to completely shut down the system when powering it off via userspace.

This package provides tools for manipulating ext2/ext3/ext4 file systems.

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

Lm-sensors is a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer systems.

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

This package provides commands to create and check XFS file systems.

CoreFreq is a CPU monitor that reports low-level processor settings and performance data with notably high precision by using a loadable Linux kernel module. Unlike most similar tools, it can be used to modify some settings if supported by the hardware and at your own risk. It's designed for 64-bit x86 Intel processors (Atom, Core2, Nehalem, SandyBridge, and newer) and compatible architectures like AMD Zen and Hygon Dhyana.

Supported processor features include:

1. time spent in C-states, including C1/C3 Auto- and UnDemotion;

2. core temperatures, voltage, and tweaking thermal limits;

3. core frequencies, ratios, and base clock rate;

4. enabling, disabling, and testing SpeedStep (EIST), Turbo Boost, and Hyper-Threading or SMT;

5. enabling or disabling data cache prefetching;

6. kernel assembly code to keep as near as possible readings of performance counters such as the TSC, UCC, and URC;

7. the number of instructions per cycle or second (IPS, IPC, and CPI);

8. memory controller geometry and RAM timings;

9. running processes' CPU affinity.

This package provides the corefreqd data collection daemon, the corefreq-cli client to visualise and control it in real time, and the corefreqk kernel module in its own separate output. Read the included README.md before loading it.

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.

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

This package provides a WiiMote driver that follows the Linux input convention. Specifically, that allows you to use the D-pad as a gamepad.

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.

Libavc1394 is a programming interface to the AV/C specification from the 1394 Trade Association. AV/C stands for Audio/Video Control.

bpftool allows for inspection and simple modification of BPF objects on the system.
