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.

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 simple Linux kernel module allows calls from user space to any ACPI method provided by your computer's firmware, by writing to /proc/acpi/call. You can pass any number of parameters of types ACPI_INTEGER, ACPI_STRING, and ACPI_BUFFER.

It grants direct and undocumented access to your hardware that may cause damage and should be used with caution, especially on untested models.

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 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.

ddate displays the Discordian date and holidays of a given date. The Discordian calendar was made popular by the "Illuminatus!" trilogy by Robert Shea and Robert Anton Wilson.

Lm-sensors is a hardware health monitoring package for Linux. It allows you to access information from temperature, voltage, and fan speed sensors. It works with most newer 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. Configuration options and patches have been applied for use with MNT/Reform systems.

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

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

CoreFreq is a CPU monitor that reports low-level processor settings and performance data with notably high precision by using a loadable Linux kernel module. Unlike most similar tools, it can be used to modify some settings if supported by the hardware and at your own risk. It's designed for 64-bit x86 Intel processors (Atom, Core2, Nehalem, SandyBridge, and newer) and compatible architectures like AMD Zen and Hygon Dhyana.

Supported processor features include:

1. time spent in C-states, including C1/C3 Auto- and UnDemotion;

2. core temperatures, voltage, and tweaking thermal limits;

3. core frequencies, ratios, and base clock rate;

4. enabling, disabling, and testing SpeedStep (EIST), Turbo Boost, and Hyper-Threading or SMT;

5. enabling or disabling data cache prefetching;

6. kernel assembly code to keep as near as possible readings of performance counters such as the TSC, UCC, and URC;

7. the number of instructions per cycle or second (IPS, IPC, and CPI);

8. memory controller geometry and RAM timings;

9. running processes' CPU affinity.

This package provides the corefreqd data collection daemon, the corefreq-cli client to visualise and control it in real time, and the corefreqk kernel module in its own separate output. Read the included README.md before loading it.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

This is the io_uring library, liburing. liburing provides helpers to setup and teardown io_uring instances, and also a simplified interface for applications that don't need (or want) to deal with the full kernel side implementation.

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.

x86_energy_perf_policy displays and updates energy-performance policy settings specific to Intel Architecture Processors. Settings are accessed via Model Specific Register (MSR) updates, no matter if the Linux cpufreq sub-system is enabled or not.

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.

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.

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.

BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature that was first added to Linux 3.15. Much of what BCC uses requires Linux 4.1 and above.

Iproute2 is a collection of utilities for controlling TCP/IP networking and traffic with the Linux kernel. The most important of these are ip, which configures IPv4 and IPv6, and tc for traffic control.

Most network configuration manuals still refer to ifconfig and route as the primary network configuration tools, but ifconfig is known to behave inadequately in modern network environments, and both should be deprecated.

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.

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.

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.

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).
