inputattach dispatches input events from several device types and interfaces and translates so that the X server can use them.

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.

The libseccomp library provides an easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism. The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by, application developers.

This package provides a Python library to access I2C and SMBus devices on Linux.

compsize takes a list of files (given as arguments) on a Btrfs file system and measures used compression types and effective compression ratio, producing a report.

A directory has no extents but has a (recursive) list of files. A non-regular file is silently ignored.

As it makes no sense to talk about compression ratio of a partial extent, every referenced extent is counted whole, exactly once -- no matter if you use only a few bytes of a 1GB extent or reflink it a thousand times. Thus, the uncompressed size will not match the number given by tar or du. On the other hand, the space used should be accurate (although obviously it can be shared with files outside our set).

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

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.

LVM2 is the logical volume management tool set for Linux-based systems. This package includes the user-space libraries and tools, including the device mapper. Kernel components are part of Linux-libre.

This package provides an advanced monitor of critical system resources, supervises the heartbeat of processes, records deadline transgressions, and initiates a controlled reset if needed.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. The software includes sandbox profiles for a number of common Linux programs. Firejail should be added to the list of setuid programs in the system configuration to work properly.

iucode_tool is a utility to work with microcode packages for Intel processors. It can convert between formats, extract specific versions, create a firmware image suitable for the Linux kernel, and more.

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

cachefilesd is a userspace daemon that manages the cache data store that is used by network file systems such as AFS and NFS to cache data locally on disk. The content of the cache is persistent over reboots.

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

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

PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to provide a core building block for the future of Linux application development.

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.

Procps is the package that has a bunch of small useful utilities that give information about processes using the Linux /proc file system. The package includes the programs free, pgrep, pidof, pkill, pmap, ps, pwdx, slabtop, tload, top, vmstat, w, watch and sysctl.

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.

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.

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.

Early OOM is a minimalist out of memory (OOM) daemon that runs in user space and provides a more responsive and configurable alternative to the in-kernel OOM killer.

The SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers.
