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.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

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.

The CRDA acts as the udev helper for communication between the kernel Linux and user space for regulatory compliance.

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

This package provides a C library with C++ bindings and command-line tools for interacting with GPIO devices that avoids the usage of older system-wide /sys interface.

ALSA provides audio and MIDI functionality to the Linux-based operating system. This package enhances ALSA by providing additional plugins which include: upmixing, downmixing, jackd and pulseaudio support for native alsa applications, format conversion (s16 to a52), and external rate conversion.

Collection of tools to query what type of USB devices are connected to the system, including lsusb. The experimental usbreset command included in the package, but be aware that it may not work for all devices.

fakeroot runs a command in an environment where it appears to have root privileges for file manipulation. This is useful for allowing users to create archives (tar, ar, deb, etc.) with files in them with root permissions and/or ownership.

Without fakeroot, one would have to have root privileges to create the constituent files of the archives with the correct permissions and ownership, and then pack them up, or one would have to construct the archives directly, without using the archiver.

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

Light is a program to send commands to screen backlight controllers under GNU/Linux. Features include:

• It does not rely on X.

• Light can automatically figure out the best controller to use, making full use of underlying hardware.

• It is possible to set a minimum brightness value, as some controllers set the screen to be pitch black at a value of 0 (or higher).

ebtables is an application program used to set up and maintain the tables of rules (inside the Linux kernel) that inspect Ethernet frames. It is analogous to the iptables application, but less complicated, due to the fact that the Ethernet protocol is much simpler than the IP protocol.

kernel-hardening-checker is a tool for checking the security hardening options of the Linux kernel. Provided preferences are based on suggestions from various sources, including:

• KSPP recommended settings

• CLIP OS kernel configuration

• Last public grsecurity patch (options which they disable)

• SECURITY_LOCKDOWN_LSM patchset

• Direct feedback from the Linux kernel maintainers

This tool supports checking Kconfig options and kernel cmdline parameters.

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.

ALSA provides audio and MIDI functionality to the Linux-based operating system.

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.

ryzenadj is an utility to adjust power management settings for AMD Ryzen mobile processors. You will need to ensure it can access /dev/mem, for instance by using the "iomem=relaxed" kernel argument.

This is a file system client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: on the server side there's nothing to do; on the client side mounting the file system is as easy as logging into the server with an SSH client.

Libevdi is a library that gives applications easy access to EVDI devices provided by the evdi driver package.

The PSM Messaging API, or PSM API, is Intel's low-level user-level communications interface for the True Scale family of products. PSM users are enabled with mechanisms necessary to implement higher level communications interfaces in parallel environments.

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.

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 commands to create and check XFS file systems.
