Linux Device Driver

Course Overview

Red Hat Enterprise Linux Kernel Device Drivers teaches experienced C programmers already familiar with the Linux kernel architecture the skills and strategies they need to develop device drivers. The Linux Device Driver Training course covers device driver models (including character, block, and network device drivers); device interaction (including port I/O, memory mapped I/O, interrupt handling, and DMA transfers); managing PCI and USB devices; strategies for deferring activity using tasklets and work queues; device registration using the Unified Device model and the sysfs filesystem; and process interaction, including basic file operations, polling, and wait queues.
