This package contains the wireless regulatory database for the CRDA. The database contains information on country-specific regulations for the wireless spectrum.

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

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.

Turbostat reports x86 processor topology, frequency, idle power state statistics, temperature, and power consumption. Some information is unavailable on older processors.

It can be used to identify machines that are inefficient in terms of power usage or idle time, report the rate of SMIs occurring on the system, or verify the effects of power management tuning.

turbostat reads hardware counters but doesn't write to them, so it won't interfere with the OS or other running processes---including multiple invocations of itself.

eCryptfs is a POSIX-compliant stacked cryptographic file system for Linux. Each file's cryptographic meta-data is stored inside the file itself, along with the encrypted contents. This allows individual encrypted files to be copied between hosts and still be decrypted with the proper key. eCryptfs is a native Linux file system, and has been part of the Linux kernel since version 2.6.19. This package contains the userland utilities to manage it.

Libraw1394 is the only supported interface to the kernel side raw1394 of the Linux IEEE-1394 subsystem, which provides direct access to the connected 1394 buses to user space. Through libraw1394/raw1394, applications can directly send to and receive from other nodes without requiring a kernel driver for the protocol in question.

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.

This is a collection of tests written over uverbs intended for use as a performance micro-benchmark. The tests may be used for hardware or software tuning as well as for functional testing.

The collection contains a set of bandwidth and latency benchmark such as:

1. Send - ib_send_bw and ib_send_lat

2. RDMA Read - ib_read_bw and ib_read_lat

3. RDMA Write - ib_write_bw and ib_wriet_lat

4. RDMA Atomic - ib_atomic_bw and ib_atomic_lat

5. Native Ethernet (when working with MOFED2) - raw_ethernet_bw, raw_ethernet_lat

TLP is a power management tool for Linux. It comes with a default configuration already optimized for battery life. Nevertheless, TLP is customizable to fulfil system requirements. TLP settings are applied every time the power supply source is changed.

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

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 the following binaries to drive the Linux Device Mapper multipathing driver:

1. multipath - Device mapper target autoconfig.

2. multipathd - Multipath daemon.

3. mpathpersist - Manages SCSI persistent reservations on dm multipath devices.

4. kpartx - Create device maps from partition tables.

As a consequence of its monolithic design, file system code for Linux normally goes into the kernel itself---which is not only a robustness issue, but also an impediment to system extensibility. FUSE, for "file systems in user space", is a kernel module and user-space library that tries to address part of this problem by allowing users to run file system implementations as user-space processes.

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.

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).

This package provides a PAM module that hands over your login password to gpg-agent. This can be useful if you are using a GnuPG-based password manager like pass.

The mcelog daemon logs memory, I/O, CPU, and other hardware errors on x86 systems running the kernel Linux. It can also perform user-defined tasks, such as bringing bad pages off-line, when configurable error thresholds are exceeded.

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).

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.

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 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.

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.

This package provides two Linux kernel drivers, ddcci and ddcci-backlight, that allows the control of DDC/CI monitors through the sysfs interface. The ddcci module creates a character device for each DDC/CI monitors in /dev/bus/ddcci/[I²C busnumber]. While the ddcci-backlight module allows the control of the backlight level or luminance property when supported under /sys/class/backlight/.

Singularity is a container platform supporting a number of container image formats. It can build SquashFS container images or import existing Docker images. Singularity requires kernel support for container isolation or root privileges.
