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.

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 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

This package contains Advanced Linux Sound Architecture topology configuration files that can be used for specific audio hardware.

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.

Extundelete is a set of tools that can recover deleted files from an ext3 or ext4 partition.

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

This package provides Python bindings for interacting with GPIO devices that avoids the usage of older system-wide /sys interface.

This package provides commands to create and check XFS file systems.

ebtables is an application program used to set up and maintain the tables of rules (inside the Linux kernel) that inspect Ethernet frames. It is analogous to the iptables application, but less complicated, due to the fact that the Ethernet protocol is much simpler than the IP protocol.

This package provides two Linux kernel drivers, ddcci and ddcci-backlight, that allows the control of DDC/CI monitors through the sysfs interface. The ddcci module creates a character device for each DDC/CI monitors in /dev/bus/ddcci/[I²C busnumber]. While the ddcci-backlight module allows the control of the backlight level or luminance property when supported under /sys/class/backlight/.

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

pflask is a simple tool for creating Linux namespace containers. It can be used for running a command or even booting an OS inside an isolated container, created with the help of Linux namespaces. It is similar in functionality to chroot, although pflask provides better isolation thanks to the use of namespaces.

Monitor a hardware random number generator, and supply entropy from that to the system kernel's /dev/random machinery.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

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.

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.

This package contains Advanced Linux Sound Architecture Use Case Manager configuration of audio input/output names and routing for specific audio hardware.

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 package provides a Linux Kernel module that controls battery charging of specific ThinkPad laptops. It also includes an improved version of the HDAPS driver. The underlying hardware interfaces are SMAPI and direct access to the embedded controller.

efibootmgr is a user-space application to modify the Intel Extensible Firmware Interface (EFI) Boot Manager. This application can create and destroy boot entries, change the boot order, change the next running boot option, and more.

This package provides small event loop that wraps the epoll family of APIs.

This package performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel.

The sysstat utilities are a collection of performance monitoring tools for Linux. These include mpstat, iostat, tapestat, cifsiostat, pidstat, sar, sadc, sadf and sa.
