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.

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.

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.

pflask is a simple tool for creating Linux namespace containers. It can be used for running a command or even booting an OS inside an isolated container, created with the help of Linux namespaces. It is similar in functionality to chroot, although pflask provides better isolation thanks to the use of namespaces.

UnionFS-FUSE is a flexible union file system implementation in user space, using the FUSE library. Mounting a union file system allows you to "aggregate" the contents of several directories into a single mount point. UnionFS-FUSE additionally supports copy-on-write.

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.

libnetfilter_conntrack is a userspace library providing a programming interface (API) to the in-kernel connection tracking state table. The library libnetfilter_conntrack has been previously known as libnfnetlink_conntrack and libctnetlink. This library is currently used by conntrack-tools among many other applications.

strace is a system call tracer, i.e. a debugging tool which prints out a trace of all the system calls made by a another process/program.

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.

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.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

jmtpfs uses FUSE to provide access to data over MTP. Unprivileged users can mount the MTP device as a file system.

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.

Hotspot is a standalone GUI for performance data analysis. It aims to be similar to KCachegrind, but for data collected with perf, a profiler for use with the kernel Linux. Its main feature is graphically visualizing a perf.data file.

This package provides userspace components for the InfiniBand subsystem of the Linux kernel. Specifically it contains userspace libraries for the following device nodes:

1. /dev/infiniband/uverbsX (libibverbs)

2. /dev/infiniband/rdma_cm (librdmacm)

3. /dev/infiniband/umadX (libibumad)

The following service daemons are also provided:

1. srp_daemon (for the ib_srp kernel module)

2. iwpmd (for iWARP kernel providers)

3. ibacm (for InfiniBand communication management assistant)

Linux kernel patches and device-trees used for the MNT Reform systems

Libnfsidmap is a library holding multiple methods of mapping names to ids and visa versa, mainly for NFSv4. It provides an extensible array of mapping functions, currently consisting of two choices: the default nsswitch and the experimental umich_ldap.

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.

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.

This is the Linux driver for the Cray/HPE Cassini 1 and 2 high-speed network interconnect (aka. Slingshot), and its Ethernet driver. It includes the uapi/misc/cxi.h C header file for use by user-land software.

Currently the Linux driver itself is missing from this package.

Libmnl is a minimalistic user-space library oriented to Netlink developers. There are a lot of common tasks in parsing, validating, constructing of both the Netlink header and TLVs that are repetitive and easy to get wrong. This library aims to provide simple helpers that allows you to re-use code and to avoid re-inventing the wheel.

This utility can read or write specific registers or all the available registers of the EC supported by the ec_sys Linux driver.

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.

This package contains Advanced Linux Sound Architecture topology configuration files that can be used for specific audio hardware.
