课程名称：Arm Barriers 101：第三部分：扩展我们的工具箱 课程概述：欢迎参加我们的Barriers 101培训课程的第三部分，这是对Arm®架构中屏障的全面深入探讨。本课程适合在Arm平台上从事系统级软件开发的软件工程师，涵盖从固件层到内核、虚拟机监控程序及设备驱动的各个层面。在这些课程中，您将学习到： - 为什么数据内存屏障并不总能保证顺序性。 - 如何在这些情况下使用其他屏障来强制执行顺序。 - Arm如何在其弱有序内存模型中正式定义顺序关系。 - 如何通过仿真测试缺失的屏障。 无论您是新手还是资深专家：我们的课程适合所有经验水平，无论您是在Arm架构方面的资深老手，还是第一次接触Arm屏障的初学者。 了解其工作原理：我们的课程在屏障主题上提供了更广泛和更深入的内容，向您展示事物的真实运作方式，更重要的是，解释其原因。 实践学习：通过30道多项选择题来巩固您的学习，每个问题和答案都有视频讲解。 认可的培训师：我们的课程由Ash Wilding撰写和制作，他曾是Arm的首席技术培训师之一，同时在亚马逊AWS和苹果公司担任内核工程师。
Welcome to Part 3 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:Why Data Memory Barriers are not always sufficient to guarantee ordering.How to use other barriers to enforce ordering in those situations.How Arm formally defines ordering relationships in its weakly-ordered memory model.How to test for missing barriers under simulation.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.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.
