The Linux kernel holds by default a lot of device drivers, but it may happen that we need to install into the system a recent one not yet imported into the kernel tree for several reasons (that is, the driver is
The Linux Kernel Device Model: An abstraction for managing components: What they are, where they are; How they're related to each other; What services they offer to users; How they respond to state changes; Merely a set of data structures!Bill Gatliff...
Device drivers: Act as an intermediary between the hardware and applications/processes. System calls and security: Receive requests for service from the application processes. Linux for Developers Developers have had a long love affair with Linux and that’s for good reason. Linux is time-tested ...
A portion of an OS -- such asWindows,LinuxormacOS-- remains memory resident. This means that a part of the OS stays loaded in the computer'sRAMwhile the system is running and handles execution for all other code, including device drivers. Device drivers relay requests for device access and...
Linux is now the most frequently ported, or uploaded, of all computer software platforms. More than 95 percent of the world’s 500 fastest computers utilize some form of a Linux operating system. Linux usage has experienced slow growth over the last decade, but as a new generation of develop...
What is /dev/zero in Linux? In Linux, device files are quite special as they provide applications to interface with device drivers which also include the/dev/zero. So in this article, I will walk you through what it is and why it is used for. ...

Chapter 3, Working with Char Drivers, examines how to implement a really simple char driver, and how to exchange data between it and the userspace. The chapter ends by proposing some examples in order to underline the Everything is a file abstraction against a device driver. Chapter 4, Usin...
Kernel modules.This is software that can be loaded and unloaded into the kernel to extend functionality without rebooting. Kernel modules are often used to support: device drivers, which use code that controls how attached devices operate;
What is a Legacy GPU? Legacy GPUs are older-generation NVIDIA GPUs which are no longer supported in the regular NVIDIA Unified UNIX Graphics Driver. Instead, these GPUs will continue to be supported through special "Legacy GPU" drivers that will be updated periodically to add support for new ...
