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

This package provides a WiiMote driver that follows the Linux input convention. Specifically, that allows you to use the D-pad as a gamepad.

bpftrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). bpftrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. The bpftrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap. bpftrace was created by Alastair Robertson.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

cpuid dumps detailed information about the CPU(s) gathered from the CPUID instruction, and also determines the exact model of CPU(s). It supports Intel, AMD, and VIA CPUs, as well as older Transmeta, Cyrix, UMC, NexGen, Rise, and SiS CPUs.

Blktrace is a block layer IO tracing mechanism which provides detailed information about request queue operations to user space. It extracts event traces from the kernel (via the relaying through the debug file system).

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.

UnionFS-FUSE is a flexible union file system implementation in user space, using the FUSE library. Mounting a union file system allows you to "aggregate" the contents of several directories into a single mount point. UnionFS-FUSE additionally supports copy-on-write.

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.

The tool conntrack provides a full featured interface that is intended to replace the old /proc/net/ip_conntrack interface. Using conntrack, you can view and manage the in-kernel connection tracking state table from userspace. On the other hand, conntrackd covers the specific aspects of stateful firewalls to enable highly available scenarios, and can be used as statistics collector as well.

Since 1.2.0, the conntrack-tools includes the nfct command line utility. This utility only supports the nfnetlink_cttimeout by now. In the long run, we expect that it will replace conntrack by providing a syntax similar to nftables.

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.

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.

This library parses raw Linux kernel trace event formats.

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.

This package contains keytable files and keyboard utilities compatible for systems using the Linux kernel. This includes commands such as loadkeys, setfont, kbdinfo, and chvt.

Tools for loading and managing Linux kernel modules, such as modprobe, insmod, lsmod, and more.

evtest is a tool to print evdev kernel events. It reads directly from the kernel device and prints a device description and the events with the value and the symbolic name.

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. Builded with --disable-sandbox-check, which is only intended for development.

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.

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.

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.

Libnfsidmap is a library holding multiple methods of mapping names to ids and visa versa, mainly for NFSv4. It provides an extensible array of mapping functions, currently consisting of two choices: the default nsswitch and the experimental umich_ldap.
