The libseccomp library provides an easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism. The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by, application developers.

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.

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.

Powerstat measures and reports your computer's power consumption in real time. On mobile PCs, it uses ACPI battery information to measure the power drain of the entire system.

Powerstat can also report RAPL power domain measurements. These are available only on some hardware such as Intel Sandybridge and newer, and cover only part of the machine's components such as CPU, DRAM, and graphics. However, they provide accurate and immediate readings and don't require a battery at all.

The output is like vmstat but also shows power consumption statistics: at the end of a run, powerstat will calculate the average, standard deviation, and minimum and maximum values. It can show a nice histogram too.

The CRDA acts as the udev helper for communication between the kernel Linux and user space for regulatory compliance.

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

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.

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.

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.

Light is a program to send commands to screen backlight controllers under GNU/Linux. Features include:

• It does not rely on X.

• Light can automatically figure out the best controller to use, making full use of underlying hardware.

• It is possible to set a minimum brightness value, as some controllers set the screen to be pitch black at a value of 0 (or higher).

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.

RadeonTop monitors resource consumption on supported AMD Radeon Graphics Processing Units (GPUs), either in real time as bar graphs on a terminal or saved to a file for further processing. It measures both the activity of the GPU as a whole, which is also accurate during OpenCL computations, as well as separate component statistics that are only meaningful under OpenGL graphics workloads.

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.

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_acct is the userspace library providing interface to extended accounting infrastructure.

1. creating accounting objects

2. retrieving accounting objects (and atomically set to zero)

3. deleting accounting objects

For the nfnetlink_acct subsystem.

This package provides a program to generate an ext2 file system as a normal (non-root) user. It does not require you to mount the image file to copy files on it, nor does it require that you become the superuser to make device nodes.

This package provides a Linux tool for controlling a PS5 DualSense controller. It has to be already connected via USB or connected via Bluetooth.

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.

lshw (Hardware Lister) is a small tool to provide detailed information on the hardware configuration of the machine. It can report exact memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, and more on DMI-capable x86 or EFI (IA-64) systems and on some PowerPC machines (PowerMac G4 is known to work).

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.

Libevdi is a library that gives applications easy access to EVDI devices provided by the evdi driver package.

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.
