linux device drivers 2nd edition phần 1

Đây là, trên bề mặt, một cuốn sách về cách viết các trình điều khiển thiết bị cho hệ thống Linux. Đó là một mục tiêu xứng đáng, tất nhiên, dòng chảy của sản phẩm phần cứng mới không có khả năng làm chậm bất cứ lúc nào ngay, và ai đó sẽ phải làm cho tất cả những tiện ích mới làm việc với Linux. | LINUX DEVICE DRIVERS O REILLY ALESSANDRO RUBINI JONATHAN CORBET A UNIX-COM PfflBLE OPERATING SYSTEM Preface This is on the surface a book about writing device drivers for the Linux system.

We hope you ll enjoy reading this book as much as we have enjoyed writing it. Alessandro s Introduction As an electronic engineer and a do-it-yourself kind of person I have always enjoyed using the computer to control external hardware. Ever since the days of my father s Apple IIe I have been looking for another platform where I could connect my custom circuitry and write my own driver software. Unfortunately the PC of the 1980s wasn t powerful enough at either the software or the hardware level the internal design of the PC is much worse than that of the Apple II and the available documentation has long been unsatisfying. But then Linux appeared and I decided to give it a try by buying an expensive 386 motherboard and no proprietary software at all. xi Preface At the time I was using Unix systems at the university and was greatly excited by the smart operating system in particular when supplemented by the even smarter utilities that the GNU project .
