As of April 2013, he is the Linux kernel maintainer for the -stable branch, [ 2] the staging subsystem, [ 2] USB, [ 2] driver core, debugfs, kref, kobject, and the sysfs kernel subsystems, [ 2] Userspace I/O (with Hans J. Koch), [ 2] and TTY layer. [ 2] He also created linux-hotplug, the ...
Video4Linux ( V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. [1] It supports many USB webcams, TV tuners, and related devices, standardizing their output, so programmers can easily add video support to their applications. Video4Linux is responsible for creating V4L2 device ...
D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
Advanced Linux Sound Architecture ( ALSA) is a software framework and part of the Linux kernel that provides an application programming interface (API) for sound card device drivers . Some of the goals of the ALSA project at its inception were automatic configuration of sound-card hardware and graceful handling of multiple sound devices in a ...

evdev (short for 'event device') is a generic input event interface in the Linux kernel and FreeBSD. [1] It generalizes raw input events from device drivers and makes them available through character devices in the /dev/input/ directory. The user-space library for the kernel component evdev is called libevdev.
SocketCAN is a set of open source CAN drivers and a networking stack contributed by Volkswagen Research to the Linux kernel. SocketCAN was formerly known as Low Level CAN Framework (LLCF). Typical CAN communication layers. With SocketCAN (left) or conventional (right). Traditional CAN drivers for Linux are based on the model of character devices.
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
