Defending against Spectre/Meltdown and performing break-before-make sequences.
Welcome to Part 4 of our Barriers 101 training course, a comprehensive deep dive on barriers in the Arm® Architecture.
This course is suitable for software engineers working on Arm-based platforms on system-level software, from down at the firmware layer all the way up through to the kernel, hypervisor, and device drivers.
In these lessons, you'll learn:
How speculative side-channel attacks like Spectre and Meltdown work.
How we can use barriers to control speculation and to defend against these kinds of attacks.
How failing to correctly perform break-before-make sequences when making certain modifications to the page tables may lead to all sorts of nasty, horrible-to-debug issues.
How to use barriers to correctly perform such sequences.
From beginner to expert: Our courses are suitable for all levels of experience, whether you're already a seasoned veteran of the Arm Architecture or you're seeing Arm Barriers for the very first time.
How it really works: Our courses go both broader and deeper on the topic of barriers than anyone else; we show you how things really work, and more importantly, why.
Learning is doing: Reinforce your learning with 30 multiple-choice quiz questions including a video walkthrough of each question and answer, followed by a full course revision session touching on every lesson from all four parts of the entire Barriers 101 training course.
Recognised trainer: Our courses are written and produced by Ash Wilding, formerly one of Arm's lead technical trainers and a kernel engineer at both Amazon AWS and Apple.
