Seeking SRE: Conversations About Running Production Systems at Scale

Seeking SRE: Conversations About Running Production Systems at Scale Lowest new price: $42.74
List price: $44.99

Organizations—big and small—have started to realize just how crucial system and application reliability is to their business. At the same time, they’ve also learned just how difficult it is to maintain that reliability while iterating at the speed demanded by the marketplace. Site Reliability Engineering (SRE) is a proven approach to this challenge.

SRE is a large and rich topic to discuss. Google led the way with Site Reliability Engineering, the wildly successful O’Reilly book that described Google’s creation of the discipline and the implementation that has allowed them to operate at a planetary scale. Inspired by that earlier work, this book explores a very different part of the SRE space.

The more than two dozen chapters in Seeking SRE bring you into some of the important conversations going on in the SRE world right now. Listen as engineers and other leaders in the field discuss different ways of implementing SRE and SRE principles in a wide variety of settings; how SRE relates to other approaches like DevOps; the specialities on the cutting edge that will soon be common place in SRE; best practices and technologies that make practicing SRE easier; and finally hear what people have to say about the important, but rarely discussed human side of SRE.

David N. Blank-Edelman is the book’s curator and editor.

Book Description

Linux kernel is a complex, portable, modular and widely used piece of software, running on around 80% of servers and embedded systems in more than half of devices throughout the world. Device drivers play a critical role in how well a Linux system performs. As Linux has turned out to be one of the most popular operating systems used, the interest in developing proprietary device drivers is also increasing steadily.

This book then covers drivers development based on various Linux subsystems such as memory management, PWM, RTC, IIO, IRQ management, and so on. The book also offers a practical approach to direct memory access and network device drivers.

By the end of this book, you will be comfortable with the concept of device driver development and will be in a position to write any device driver from scratch using the latest kernel version (v4.13 at the time of writing this book).

What you will learn

  • Use kernel facilities to develop powerful drivers
  • Develop drivers for widely used I2C and SPI devices and use the regmap API
  • Write and support devicetree from within your drivers
  • Program advanced drivers for network and frame buffer devices
  • Delve into the Linux irqdomain API and write interrupt controller drivers
  • Enhance your skills with regulator and PWM frameworks
  • Develop measurement system drivers with IIO framework
  • Get the best from memory management and the DMA subsystem
  • Access and manage GPIO subsystems and develop GPIO controller drivers
