This tutorial walks you through checking the OS architecture, preparing the environment, downloading and extracting the MySQL 5.7 ARM package, configuring my.cnf, setting up auto‑start and environment variables, initializing the server, securing the root account, and configuring master‑slave replication on Linux.
The article explains how AArch64 stack unwinding works using both frame‑pointer based methods and DWARF .eh_frame/.debug_frame CFI data, detailing the calling convention, compiler effects, CIE/FDE structures, and their integration into Android’s simpleperf profiler for accurate back‑traces.
The article investigates why BPF LSM programs fail to load on aarch64 kernels, uses ftrace‑based tools such as bpftrace and trace‑cmd to trace kernel execution, discovers missing arch_prepare_bpf_trampoline support in 5.15 and 6.1, and shows that a patch merged into the mainline kernel restores functionality for upcoming releases.
Android’s Shadow Call Stack (SCS), silently enabled since Android R on AArch64 devices, stores return addresses in a protected register‑based stack separate from the regular stack, complementing stack canaries and requiring hardware support, while developers can activate it via -fsanitize=shadow-call-stack and avoid using X18 elsewhere.
This article explains Android's Shadow Call Stack (SCS) security mechanism, its hardware dependencies, enabling methods, and how it protects return addresses on AArch64 kernels, illustrated with code examples and real‑world deployment results.
This article explains the principles behind HWAddressSanitizer (HWASAN), how it uses the AArch64 Top‑Byte‑Ignore hardware feature to provide lower‑overhead memory error detection than ASAN, and walks through practical examples, implementation details, and LLVM integration for C/C++ developers.
This article provides a comprehensive overview of the ARMv8‑A architecture, detailing its two execution states (AArch64 and AArch32), register sets, exception levels, instruction sets, key features, and the mechanisms that enable virtualization such as hypervisor operation at EL2, stage‑2 address translation, VMID handling, and device emulation through SMMU.
This article provides a comprehensive overview of the ARMv8 architecture, detailing its 32‑bit and 64‑bit execution states, backward compatibility, key enhancements such as larger register pools and address spaces, and the specific characteristics of ARMv8‑A processors like Cortex‑A53, A57, and A73.
This article provides a comprehensive overview of the ARMv8 architecture, describing its 32‑bit (AArch32) and 64‑bit (AArch64) execution states, the benefits of larger registers and address spaces, and detailed specifications of Cortex‑A53, Cortex‑A57, and Cortex‑A73 processors.
