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.

acpid is designed to notify user-space programs of Advanced Configuration and Power Interface (ACPI) events. acpid should be started during the system boot, and will run as a background process. When an ACPI event is received from the kernel, acpid will examine the list of rules specified in /etc/acpi/events and execute the rules that match the event.

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.

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.

The GPM (general-purpose mouse) daemon is a mouse server for applications running on the Linux console. It allows users to select items and copy/paste text in the console and in xterm.

This package provides a FUSE-based file system that provides read and write access to exFAT devices.

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.

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.

NTFS-3G provides read-write access to NTFS file systems, which are commonly found on Microsoft Windows. It is implemented as a FUSE file system. The package provides additional NTFS tools.

The tool conntrack provides a full featured interface that is intended to replace the old /proc/net/ip_conntrack interface. Using conntrack, you can view and manage the in-kernel connection tracking state table from userspace. On the other hand, conntrackd covers the specific aspects of stateful firewalls to enable highly available scenarios, and can be used as statistics collector as well.

Since 1.2.0, the conntrack-tools includes the nfct command line utility. This utility only supports the nfnetlink_cttimeout by now. In the long run, we expect that it will replace conntrack by providing a syntax similar to nftables.

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.

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.

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).

OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric communication services to applications. OFI is best described as a collection of libraries and applications used to export fabric services. The key components of OFI are: application interfaces, provider libraries, kernel services, daemons, and test applications.

Libfabric is a core component of OFI. It is the library that defines and exports the user-space API of OFI, and is typically the only software that applications deal with directly. It works in conjunction with provider libraries, which are often integrated directly into libfabric.

This library provides APIs to access the Linux kernel's trace file system.

This package provides boltd, a userspace daemon for Thunderbolt devices, and boltctl, a command-line utility for managing those devices.

The daemon boltd exposes devices via D-Bus to clients. It also stores a database of previously authorized devices and will, depending on the policy set for the individual devices, automatically authorize newly connected devices without user interaction.

The command-line utility boltctl manages Thunderbolt devices via boltd. It can list devices, monitor changes, and initiate authorization of devices.

This package provides a kernel module that is capable of resetting hardware devices into a state where they can be re-initialized or passed through into a virtual machine (VFIO). While it would be great to have these in the kernel as PCI quirks, some of the reset procedures are very complex and would never be accepted as a quirk (ie AMD Vega 10).

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.

mdadm is a tool for managing Linux Software RAID arrays. It can create, assemble, report on, and monitor arrays. It can also move spares between raid arrays when needed.

snapscreenshot saves a screenshot of one or more Linux text consoles as a Targa (.tga) image. It can be used by anyone with read access to the relevant /dev/vcs* file(s).

Modprobed-db is a useful utility for users wishing to build a minimal kernel via a make localmodconfig. In a nutshell, this make target creates a config based on the current config and a list of modules you define (that modprobed-db keeps for you). It then disables any module option that is not needed thus not building extraneous modules. This results in a system-specific, streamlined kernel package and footprint as well as reduced compilation times.

Modprobed-db simply logs every module ever probed on the target system to a text-based database ($XDG_CONFIG_HOME/modprobed-db), which can be read directly by make localmodconfig as described above.

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux-based operating system.
