Linux Device Driver Training Introduction

• LINUX DEVICE DRIVER TRAINING Course is all about
  how to develop device drivers for linux, how
  device drivers work with the Linux kernel, how to
  compile and load drivers, how to debug drivers,
  as well as other essential topics. LINUX DEVICE
  DRIVER TRAINING course is designed for software
  engineers who are new to Linux device drivers.
  Attendees should have experience with C, be able
  to perform basic Unix commands, and have some
  experience with the basic Gnu tools of gcc, gdb,
  and make. 
• Embedded Linux Device Driver training helps in
  understanding of the essentials of Linux device
  drivers, purpose and functionality of device
  drivers and how Compiling and linking device
  drivers does is processed. Register today at the
  website to learn more and call us directly at the
  help desk.

Prerequisites of Linux Device Driver Training

• Familiarity with Basic Linux Kernel
• Understanding of C language.
• Knowledge of how to write kernel program.
• Understanding of basic utilities of Linux
  operating system e.g insmod, rmmod, dmesg etc.
• Understanding of Linux kernel internals.
• And obviously you should know about your device.
  Understand its specification. Learn to read and
  understand datasheet of the device. It will help
  to write efficient device driver code.

Differences between Kernel Modules and User
Programs

• Kernel modules have separate address space.A
  module runs in kernel space. An application runs
  in user space. System software is protected from
  user programs. Kernel space and user space have
  their own memory address spaces.
• Kernel modules have higher execution
  privilege.Code that runs in kernel space has
  greater privilege than code that runs in user
  space.
• Kernel modules do not execute sequentially.A user
  program typically executes sequentially and
  performs a single task from beginning to end. A
  kernel module does not execute sequentially. A
  kernel module registers itself in order to serve
  future requests.
• Kernel modules use different header files.Kernel
  modules require a different set of header files
  than user programs require.

Learn Kernel space and User space in Linux Device
Driver Training

• Do I have your attention? Kernel space is where
  the operating system runs and provides services.
  User space is where user processes run. What is a
  process? A process is a performance instance of a
  program. One of the roles of the Kernel is to
  direct individual user processes within this
  space and to stop them from interfering with each
  other.
• Note that the device driver runs in kernel space
  and not in user space. All applications run in
  user space but not in kernel space. Every device
  driver programmer should remember these points.

Conclusion of Embedded Linux Device Driver
training

• Whats the bottom line? Linux also supports
  multiple file system types that are different
  ways of organizing data on the physical medium.
  For example, disks may be formatted with the
  Linux standard ext3 file system or the commonly
  used FAT file system or several others. The
  various parts of the kernel interact with the
  memory management subsystem all the way through a
  set of function calls, ranging from the simple
  malloc/free pair to much more complex
  functionalities. There are lots of opportunities
  in the market for Embedded Linux Device Driver
  training. So what are you waiting for? Come be
  part of Linux and utilize the services it
  provides. Join in Global online trainings for
