Libbpf supports building BPF CO-RE-enabled applications, which, in contrast to BCC, do not require the Clang/LLVM runtime or linux kernel headers.

bpftool allows for inspection and simple modification of BPF objects on the system.

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.

This package provides a way to record and replay device descriptions and events, making it possible to emulate input devices through the Linux kernel's input system. Emulated devices are for most practical purposes indistinguishable from real devices.

It provides a command line program and also a Python library.

The primary purpose of Csmith is to find compiler bugs with random programs using differential testing.

Xsensors reads data from the libsensors library regarding hardware health such as temperature, voltage and fan speed and displays the information in a digital read-out.

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.

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

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.

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.

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.

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.

psmisc is a set of small utilities that use the proc file system.

• fuser identifies processes using files or sockets;

• killall kills processes by name;

• prtstat prints statistics of a process;

• pslog prints the log file(s) of a process;

• pstree shows the currently running processes as a tree;

• peekfd shows the data travelling over a file descriptor.

This package contains utilities for accessing the powercap Linux kernel feature through sysfs. It includes an implementation for working with Intel RAPL. It provides the commands powercap-info and powercap-set.

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.

Procps is the package that has a bunch of small useful utilities that give information about processes using the Linux /proc file system. The package includes the programs free, pgrep, pidof, pkill, pmap, ps, pwdx, slabtop, tload, top, vmstat, w, watch and sysctl.

inputattach dispatches input events from several device types and interfaces and translates so that the X server can use them.

Dual Function Keys is a plugin for interception-tools that allows one to send arbitrary keycodes when a given key is tapped or held.

The EVDI is a Linux kernel module that enables management of multiple screens, allowing user-space programs to take control over what happens with the image. It is essentially a virtual display for which applications using the libevdi library can add, remove, and receive screen updates.

The EVDI driver uses the standard Linux DRM. Its displays can be controlled by standard tools such as xrandr and display settings applets in graphical environments

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.

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

Interception Tools provides a composable infrastructure on top of libudev and libevdev. The following utilities are provided:

• udevmon --- monitor input devices for launching tasks

• intercept --- redirect device input events to stdout

• uinput --- redirect device input events from stding to virtual device

• mux --- mux streams of input events

The bbswitch module provides a way to toggle the Nvidia graphics card on Optimus laptops.

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.
