“Probably the main broad ranging and whole Linux gadget driving force e-book I’ve read.”

--Alan Cox, Linux Guru and Key Kernel Developer

“Very accomplished and certain, masking virtually each Linux equipment 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 sensible consultant to Writing Linux equipment Drivers

Linux now bargains a really strong surroundings for driving force improvement: with today’s kernels, what as soon as required years of improvement time may be entire in days. during this functional, example-driven booklet, one of many world’s such a lot skilled Linux driving force builders systematically demonstrates the way to strengthen trustworthy Linux drivers for almost any gadget. Essential Linux equipment Drivers is for any programmer with a operating wisdom of working platforms and C, together with programmers who've by no means written drivers sooner than. Sreekrishnan Venkateswaran makes a speciality of the necessities, bringing jointly the entire techniques and methods you wish, whereas warding off themes that basically subject in hugely really expert events. Venkateswaran starts through reviewing the Linux 2.6 kernel functions which are such a lot proper to driving force builders. He introduces uncomplicated gadget periods; then turns to serial buses equivalent to I2C and SPI; exterior buses reminiscent of PCMCIA, PCI, and USB; video, audio, block, community, and instant gadget 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 proper kernel resource documents, and walks via constructing a whole example.
