Linux Process Source Code Pointers

Processes are a fundamental abstraction of the operating system. To support processes, the OS uses two key data structures (task_struct and thread_info), as well as a host of auxiliary functions for managing processes in the system.

arch/arm/include/asm/thread_info.h - Definition of the thread_info structure.

include/linux/sched.h - Definition of the task_struct structure, plus many process management functions.

arch/arm/include/asm/switch_to.h - Defintion of the process switch routine

arch/arm/kernel/entry-armv.S - Implementation of the assembly level process switch routine (__switch_to)
