evtest is a tool to print evdev kernel events. It reads directly from the kernel device and prints a device description and the events with the value and the symbolic name.

Blktrace is a block layer IO tracing mechanism which provides detailed information about request queue operations to user space. It extracts event traces from the kernel (via the relaying through the debug file 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.

Utilities for Linux's Ethernet bridging facilities. A bridge is a way to connect two Ethernet segments together in a protocol independent way. Packets are forwarded based on Ethernet address, rather than IP address (like a router). Since forwarding is done at Layer 2, all protocols can go transparently through a bridge.

x86_energy_perf_policy displays and updates energy-performance policy settings specific to Intel Architecture Processors. Settings are accessed via Model Specific Register (MSR) updates, no matter if the Linux cpufreq sub-system is enabled or not.

lshw (Hardware Lister) is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, and more on DMI-capable x86 or EFI (IA-64) systems and on some PowerPC machines (PowerMac G4 is known to work).

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.

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 performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel.

This package provides a shell script to assess your system's resilience against the several transient execution CVEs that were published since early 2018, and gives guidance as to how to mitigate them.

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

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 package provides statically-linked e2fsck command taken from the e2fsprogs package. It is meant to be used in initrds.

BlueZ provides support for the core Bluetooth layers and protocols. It is flexible, efficient and uses a modular implementation.

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

Prevents shock damage to the internal spinning hard drive(s) of some HP and Dell laptops. When sudden movement is detected, all input/output operations on the drive are suspended and its heads are parked on the ramp, where they are less likely to cause damage to the spinning disc. Requires a drive that supports the ATA/ATAPI-7 IDLE IMMEDIATE command with unload feature, and a laptop with an accelerometer. It has no effect on SSDs.

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.

This package provides a Linux tool for controlling a PS5 DualSense controller. It has to be already connected via USB or connected via Bluetooth.

Libnftnl is a userspace library providing a low-level netlink programming interface to the in-kernel nf_tables subsystem. The library libnftnl has been previously known as libnftables. This library is currently used by nftables.

The Falco security libraries include libsinsp and libscap. libscap manages the data capture process, while libsinsp is a system inspection library that enriches events from libscap with machine state. libsinsp also performs events filtering with rule evaluation through its internal rule engine. These libraries are used by the sysdig command-line utility.

libnetfilter_cttimeout is the userspace library that provides the programming interface to the fine-grain connection tracking timeout infrastructure. With this library, you can create, update and delete timeout policies that can be attached to traffic flows. This library is used by conntrack-tools.

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.

Python-evdev provides bindings to the generic input event interface in Linux. The evdev interface serves the purpose of passing events generated in the kernel directly to userspace through character devices that are typically located in /dev/input/.

This package also comes with bindings to uinput, the userspace input subsystem. uinput allows userspace programs to create and handle input devices that can inject events directly into the input subsystem.

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.
