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

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 is a port of the FreeBSD userland for Linux provided by the Chimera Linux distribution. Essentially, it is a collection of UNIX tools such as grep, cp, vi, etc. and can be used as an alternative to the corresponding implementations from the GNU project.

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.

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.

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.

iotop identifies which processes and threads are most responsible for I/O activity such as disc reads and writes. It sorts them in a live, interactive table overview similar to that of the well-known top.

This information makes it much easier for an administrator to see which tasks are blocking others and adjust their priority (using ionice) or stop or kill them altogether.

mdadm is a tool for managing Linux Software RAID arrays. It can create, assemble, report on, and monitor arrays. It can also move spares between raid arrays when needed.

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.

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 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.

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.

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

PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to provide a core building block for the future of Linux application development.

The GPM (general-purpose mouse) daemon is a mouse server for applications running on the Linux console. It allows users to select items and copy/paste text in the console and in xterm.

Libcap2 provides a programming interface to POSIX capabilities on Linux-based operating systems.

python-spython is a Python library to interact with Singularity containers.

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. Configuration options and patches have been applied for use with MNT/Reform systems.

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.

EROFS is a compressed, read-only file system optimized for resource-scarce devices. This package provides user-space tools for creating EROFS file systems.

ryzenadj is an utility to adjust power management settings for AMD Ryzen mobile processors. You will need to ensure it can access /dev/mem, for instance by using the "iomem=relaxed" kernel argument.
