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.

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

psmisc is a set of small utilities that use the proc file system.

• fuser identifies processes using files or sockets;

• killall kills processes by name;

• prtstat prints statistics of a process;

• pslog prints the log file(s) of a process;

• pstree shows the currently running processes as a tree;

• peekfd shows the data travelling over a file descriptor.

This package provides userspace components for the InfiniBand subsystem of the Linux kernel. Specifically it contains userspace libraries for the following device nodes:

1. /dev/infiniband/uverbsX (libibverbs)

2. /dev/infiniband/rdma_cm (librdmacm)

3. /dev/infiniband/umadX (libibumad)

The following service daemons are also provided:

1. srp_daemon (for the ib_srp kernel module)

2. iwpmd (for iWARP kernel providers)

3. ibacm (for InfiniBand communication management assistant)

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/.

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.

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.

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).

libnetfilter_log is a userspace library providing interface to packets that have been logged by the kernel packet filter. It is is part of a system that deprecates the old syslog/dmesg based packet logging. This library has been previously known as libnfnetlink_log.

1. receiving to-be-logged packets from the kernel nfnetlink_log subsystem

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.

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.

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.

This package provides the kexec program and ancillary utilities. Using kexec, it is possible to boot directly into a new kernel from the context of an already-running kernel, bypassing the normal system boot process.

BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature that was first added to Linux 3.15. Much of what BCC uses requires Linux 4.1 and above.

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

This library parses raw Linux kernel trace event formats.

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.

FBGrab is a framebuffer screenshot program that captures the Linux framebuffer and converts it to a PNG image. It can also convert a framebuffer dump file (copy) to a PNG image.

This is the io_uring library, liburing. liburing provides helpers to setup and teardown io_uring instances, and also a simplified interface for applications that don't need (or want) to deal with the full kernel side implementation.

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

This package provides a statically linked ntfsfix taken from the ntfs-3g package. It is meant to be used in initrds.

Collection of tools to query what type of USB devices are connected to the system, including lsusb. The experimental usbreset command included in the package, but be aware that it may not work for all devices.

mbpfan is a fan control daemon for Apple Macbooks. It uses input from the coretemp module and sets the fan speed using the applesmc module. It can be executed as a daemon or in the foreground with root privileges.
