“Probably the main broad ranging and whole Linux equipment driving force publication I’ve read.”

--Alan Cox, Linux Guru and Key Kernel Developer

“Very entire and specified, protecting virtually each Linux machine driving force type.”

--Theodore Ts’o, First Linux Kernel Developer in North the USA and leader Platform Strategist of the Linux Foundation

The such a lot useful consultant to Writing Linux equipment Drivers

Linux now bargains a really strong atmosphere for driving force improvement: with today’s kernels, what as soon as required years of improvement time could be finished in days. during this useful, example-driven e-book, one of many world’s such a lot skilled Linux motive force builders systematically demonstrates find out how to increase trustworthy Linux drivers for almost any gadget. Essential Linux equipment Drivers is for any programmer with a operating wisdom of working structures and C, together with programmers who've by no means written drivers earlier than. Sreekrishnan Venkateswaran makes a speciality of the necessities, bringing jointly all of the ideas and methods you would like, whereas warding off subject matters that simply topic in hugely really expert events. Venkateswaran starts off by way of reviewing the Linux 2.6 kernel functions which are such a lot suitable to motive force builders. He introduces easy gadget sessions; then turns to serial buses akin to I2C and SPI; exterior buses corresponding to PCMCIA, PCI, and USB; video, audio, block, community, and instant machine drivers; user-space drivers; and drivers for embedded Linux–one of today’s quickest starting to be parts of Linux improvement. for every, Venkateswaran explains the expertise, inspects appropriate kernel resource documents, and walks via constructing a whole example.

• Addresses drivers mentioned in no different e-book, together with drivers for I2C, video, sound, PCMCIA, and forms of flash memory

• Demystifies crucial kernel companies and amenities, together with kernel threads and helper interfaces

• Teaches polling, asynchronous notification, and I/O control

• Introduces the Inter-Integrated Circuit Protocol for embedded Linux drivers

• Covers multimedia machine drivers utilizing the Linux-Video subsystem and Linux-Audio framework

• exhibits how Linux implements aid for instant applied sciences reminiscent of Bluetooth, Infrared, WiFi, and mobile networking

• Describes the whole motive force improvement lifecycle, via debugging and maintenance

• contains reference appendixes overlaying Linux meeting, BIOS calls, and Seq files
