Thinkfan is a simple fan control program. It reads temperatures, checks them against configured limits and switches to appropriate (also pre-configured) fan level. It requires a working thinkpad_acpi or any other hwmon driver that enables temperature reading and fan control from userspace.

This package provides Python bindings for interacting with GPIO devices that avoids the usage of older system-wide /sys interface.

The Embedded Linux* Library (ELL) provides core, low-level functionality for system daemons. It typically has no dependencies other than the Linux kernel, C standard library, and libdl (for dynamic linking). While ELL is designed to be efficient and compact enough for use on embedded Linux platforms, it is not limited to resource-constrained systems.

Tpacpi-bat is a command-line interface to control battery charging on Lenovo ThinkPad models released after 2011, starting with the xx20 series. It can query and set the thresholds at which one or both batteries will start and stop charging, inhibit charging batteries for a set period of time, or force them to discharge when they otherwise would not.

This tool merely exposes ACPI calls provided by the acpi_call Linux kernel module provided by the acpi-call-linux-module package, which must be installed and loaded separately. Only the original vendor firmware is supported.

This package provides a way to access the System Management Unit for certain AMD Ryzen processors. This includes access to the System Management Network.

Headers of the Linux-Libre kernel.

perf is a tool suite for profiling using hardware performance counters, with support in the Linux kernel. perf can instrument CPU performance counters, tracepoints, kprobes, and uprobes (dynamic tracing). It is capable of lightweight profiling. This package contains the user-land tools and in particular the perf command.

A *Free* project to implement OSF's RFC 86.0. Pluggable authentication modules are small shared object files that can be used through the PAM API to perform tasks, like authenticating a user at login. Local and dynamic reconfiguration are its key features.

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.

haveged generates an unpredictable stream of random numbers for use by Linux's /dev/random and /dev/urandom devices. The kernel's standard mechanisms for filling the entropy pool may not be sufficient for systems with high needs or limited user interaction, such as headless servers.

haveged runs as a privileged daemon, harvesting randomness from the indirect effects of hardware events on hidden processor state using the HAVEGE algorithm. It tunes itself to its environment and provides the same built-in test suite for the output stream as used on certified hardware security devices.

The quality of the randomness produced by this algorithm has not been proven. It is recommended to run it together with another entropy source like rngd, and not as a replacement for it.

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.

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.

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

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.

ipvsadm(8) is used to set up, maintain or inspect the virtual server table in the Linux kernel. The Linux Virtual Server can be used to build scalable network services based on a cluster of two or more nodes.

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).

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 is a Python program with a top like user interface to show the processes currently causing I/O.

The cpufrequtils suite contains utilities to retrieve CPU frequency information, and set the CPU frequency if supported, using the cpufreq capabilities of the Linux kernel.

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.

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

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.

Control groups is Linux kernel method for process resource restriction, permission handling and more. This package provides userspace interface to this kernel feature.

bpftrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). bpftrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. The bpftrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap. bpftrace was created by Alastair Robertson.
