This package provides a library called libpfm4, which is used to develop monitoring tools exploiting the performance monitoring events such as those provided by the Performance Monitoring Unit (PMU) of modern processors.

Libpfm4 helps convert from an event name, expressed as a string, to the event encoding that is either the raw event as documented by the hardware vendor or the OS-specific encoding. In the latter case, the library is able to prepare the OS-specific data structures needed by the kernel to setup the event.

libpfm4 provides support for the perf_events interface, which was introduced in Linux 2.6.31.

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 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.

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

iptables is the user-space command line program used to configure the Linux 2.4.x and later IPv4 packet filtering ruleset (firewall), including NAT (Network Address Translation).

This package also includes ip6tables, which is used to configure the IPv6 packet filter.

Both commands are targeted at system administrators.

iotop identifies which processes and threads are most responsible for I/O activity such as disc reads and writes. It sorts them in a live, interactive table overview similar to that of the well-known top.

This information makes it much easier for an administrator to see which tasks are blocking others and adjust their priority (using ionice) or stop or kill them altogether.

Headers of the Linux-Libre kernel.

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).

fakechroot runs a command in an environment were is additional possibility to use chroot command without root privileges. This is useful for allowing users to create own chrooted environment with possibility to install another packages without need for root privileges.

It works by providing libfakechroot.so, a shared library meant to be set as LD_PRELOAD to override the C library file system functions.

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.

Irqbalance is a daemon to help balance the CPU load generated by interrupts across all of a systems CPUs. Irqbalance identifies the highest volume interrupt sources, and isolates each of them to a single unique CPU, so that load is spread as much as possible over an entire processor set, while minimizing cache miss rates for irq handlers.

The primary purpose of Csmith is to find compiler bugs with random programs using differential testing.

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.

The kernel Linux's frame buffers provide a simple interface to different kinds of graphic displays. The fbset utility can query and change various device settings such as depth, virtual resolution, and timing parameters.

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.

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

Keyd is a keyboard remapping utility with intuitive ini configuration file format. Keyd has several features, many of which are traditionally only found in custom keyboard firmware like QMK.

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

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

This package provides hardware definitions and C headers for use by the Linux driver and by user-space applications for the Cassini/Slingshot high-speed network interconnect made by HPE (formerly Cray). User-land software uses cxi_prov_hw.h from this package.

The inih (INI Not Invented Here) library is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and name: value entries.

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.

This package provides a statically linked ntfsfix taken from the ntfs-3g package. It is meant to be used in initrds.
