Linux Tutorial: How a Linux System Call Works – The Linux Foundation
In this 3-minute “taste of training” video, The Linux Foundation’s Training Instructor John Bonesio uses the whiteboard to demonstrate how Linux transitions from user mode into kernel mode with a system call.
He discusses the role of system call handlers, what happens on the user and system stacks and how it works with an array of system calls that point to a series of routines.
