Libudev
udev (userspace ) is a device manager for the Linux kernel. As the successor of devfsd and hotplug, udev primarily manages device nodes in the 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. Rationale It is an operating system's kernel that is responsible for providing an abstract interface of the hardware to the rest of the software. Being a monolithic kernel, the Linux kernel does exactly that: device drivers are part of the Linux kernel, and make up more than half of its source code. Hardware can be accessed through system calls or over their device nodes. To be able to deal with peripheral devices that are hotplug-capable in a user-friendly way, a part of handling all of these hotplug-capable hardware devices was handed over from the kernel to a daemon (computing), daemon running in user-space. Running in user space s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greg Kroah-Hartman
Greg Kroah-Hartman (GKH) is a major Linux kernel developer. he is the Linux kernel maintainer for the branch, the staging subsystem, USB, driver core, debugfs, kref, kobject, and the sysfs kernel subsystems, Userspace I/O (with Hans J. Koch), and TTY layer. He also created linux-hotplug, the udev project, and the Linux Driver Project. He worked for Novell in the SUSE Labs division and, , works at the Linux Foundation. Biography Kroah-Hartman is a co-author of ''Linux Device Drivers'' (3rd Edition) and author of ''Linux Kernel in a Nutshell'', and used to be a contributing editor for ''Linux Journal''. He also contributes articles to LWN.net, the Linux news site. Kroah-Hartman frequently helps in the documentation of the kernel and driver development through talks and tutorials. In 2006, he released a CD image of material to introduce a programmer to working on Linux device driver development. He also initiated the development of openSUSE Tumbleweed, the rolling release ...
