The mcelog daemon logs memory, I/O, CPU, and other hardware errors on x86 systems running the kernel Linux. It can also perform user-defined tasks, such as bringing bad pages off-line, when configurable error thresholds are exceeded.

libnvme provides type definitions for NVMe specification structures, enumerations, and bit fields, helper functions to construct, dispatch, and decode commands and payloads, and utilities to connect, scan, and manage nvme devices on a Linux system.

This simple tool injects fake MCEs into a running Linux kernel, to debug or test the kernel's EDAC-handling code specific to x86 and x86_64 platforms.

Real MCEs are internal CPU errors. Handling them correctly can be important to system stability and even prevent physical damage. In contrast, simulated MCEs produced by mce-inject are purely synthetic: injection happens only at the software level, inside the kernel, and is not visible to the platform hardware or firmware.

A convenient feature of mce-inject is that the input language used to describe MCEs is similar to the format used in Linux panic messages, with a few extensions. In general, you should be able to pipe in any logged MCE panic to simulate that same MCE.

The target kernel must have the CONFIG_X86_MCE_INJECT option enabled and the mce-inject module loaded if it exists.

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.

This simple daemon feeds entropy from the CPU Jitter RNG core to the kernel Linux's entropy estimator. This prevents the /dev/random device from blocking and should benefit users of the preferred /dev/urandom and getrandom() interfaces too.

The CPU Jitter RNG itself is part of the kernel and claims to provide good entropy by collecting and magnifying differences in CPU execution time as measured by the high-resolution timer built into modern CPUs. It requires no additional hardware or external entropy source.

The random bit stream generated by jitterentropy-rngd is not processed by a cryptographically secure whitening function. Nonetheless, its authors believe it to be a suitable source of cryptographically secure key material or other cryptographically sensitive data.

If you agree with them, start this daemon as early as possible to provide properly seeded random numbers to services like SSH or those using TLS during early boot when entropy may be low, especially in virtualised environments.

Util-linux is a diverse collection of Linux kernel utilities. It provides dmesg and includes tools for working with file systems, block devices, UUIDs, TTYs, and many other tools.

bin-graph provides a simple way of visualizing the different regions of a binary file.

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.

Dwarves is a set of tools that use the debugging information inserted in ELF binaries by compilers such as GCC, used by well known debuggers such as GDB.

Utilities in the Dwarves suite include pahole, that can be used to find alignment holes in structures and classes in languages such as C, C++, but not limited to these. These tools can also be used to encode and read the BTF type information format used with the kernel Linux bpf syscall.

The codiff command can be used to compare the effects changes in source code generate on the resulting binaries.

The pfunct command can be used to find all sorts of information about functions, inlines, decisions made by the compiler about inlining, etc.

The pahole command can be used to use all this type information to pretty print raw data according to command line directions.

Headers can have its data format described from debugging info and offsets from it can be used to further format a number of records.

Finally, the btfdiff command can be used to compare the output of pahole from BTF and DWARF, to make sure they produce the same results.

Aumix adjusts an audio mixer from X, the console, a terminal, the command line or a script.

FuseISO is a FUSE module to mount ISO file system images (.iso, .nrg, .bin, .mdf and .img files). It supports plain ISO9660 Level 1 and 2, Rock Ridge, Joliet, and zisofs.

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

This package provides an advanced monitor of critical system resources, supervises the heartbeat of processes, records deadline transgressions, and initiates a controlled reset if needed.

This package contains the wireless regulatory database for the CRDA. The database contains information on country-specific regulations for the wireless spectrum.

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).

This is a file system client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: on the server side there's nothing to do; on the client side mounting the file system is as easy as logging into the server with an SSH client.

Wireless Tools are used to manipulate the now-deprecated Linux Wireless Extensions; consider using iw instead. The Wireless Extension was an interface allowing you to set Wireless LAN specific parameters and get the specific stats. It is deprecated in favor the nl80211 interface.

This package provides a statically linked xfs_repair taken from the xfsprogs package. It is meant to be used in initrds.

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

The VHBA module is the link between the CDemu user-space daemon and the kernel Linux. It acts as a low-level SCSI driver that emulates a virtual SCSI adapter which can have multiple virtual devices attached to it. Its typical use with CDEmu is to emulate optical devices such as DVD and CD-ROM drives.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. The software includes sandbox profiles for a number of common Linux programs. Firejail should be added to the list of setuid programs in the system configuration to work properly.

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