## Instructions and Navigations
All of the code is organized into folders. For example, Chapter02.
The code will look like the following:
```
struct mutex {
atomic_long_t owner;
spinlock_t wait_lock;
#ifdef CONFIG_MUTEX_SPIN_ON_OWNER
struct optimistic_spin_queue osq; /* Spinner MCS lock */
```
**Following is what you need for this book:**
This Linux OS book is for embedded system and embedded Linux enthusiasts/developers who want to get started with Linux kernel development and leverage its subsystems. Electronic hackers and hobbyists interested in Linux kernel development as well as anyone looking to interact with the platform using GPIO, IIO, and input subsystems will also find this book useful.
With the following software and hardware list you can run all code files present in the book (Chapter 1-17).
### Software and Hardware List
| Chapter | Software required | OS required |
| -------- | ------------------------------------ | ----------------------------------- |
| 1-17 | A computer with good network bandwidth and enough space and RAM to download and build Linux kernel | Preferably any Debian distribution |
| 1-17 | Any cortex -A embedded board available on market (for example UDOO quad, Jetson nano, Rasberry Pi, Beagle bone | Either a yocto/Buildroot ditribution or any embedded or vendor-specific OS (for example Rasbian for Rasberry Pi) |
