Sysfs was designed to export the information present in the device tree which would then no longer clutter up procfs. It was written by Patrick Mochel. It was written by Patrick Mochel. [ 3 ] [ 4 ] Maneesh Soni later wrote the sysfs backing store patch to reduce memory usage on large systems.
The USB Gadget fabric module enables Linux to export local storage devices via the Universal Serial Bus (USB), so that other systems can mount them as an ordinary storage device. USB was designed in the mid-1990s to standardize the connection of computer peripherals, and has also become common for data storage devices. The USB Gadget fabric ...
NDISwrapper is a free software driver wrapper that enables the use of Windows XP network device drivers (for devices such as PCI cards, USB modems, and routers) on Linux operating systems. NDISwrapper works by implementing the Windows kernel and NDIS APIs and dynamically linking Windows network drivers to this implementation.
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.
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
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.
The Linux API is composed out of the System Call Interface of the Linux kernel, the GNU C Library, libcgroup, [3] libdrm, libalsa and libevdev [4] (by freedesktop.org).. libusb is a library that provides applications with access for controlling data transfer to and from USB devices on Unix and non-Unix systems, without the need for kernel-mode drivers.
In addition, drivers export device-specific interfaces for use by user-space drivers and device-aware applications through ioctls and sysfs files. External interfaces include: memory mapping, context management, DMA operations, AGP management, vblank control, fence management, memory management, and output management.
