Technical experience sharing, welcome to follow and provide guidance. I briefly introduced KASAN in my article “Debugging Memory Leaks in the Kernel”. At that time, my understanding of the implementation principles of KASAN was still shallow. Recently, I plan to comprehensively learn and understand KASAN, and then consolidate my memory by writing this series of … Read more
Abstract The Compute Express Link (CXL) subsystem has incorporated several improvements in Linux 6.18, most notably the mainlining of the Poison Injection feature. This functionality allows user space to inject “poison” bits into CXL physical addresses through a newly created kernel-side interface, simulating device errors and validating the hardware/software exception handling paths. Additionally, the patch … Read more
What is Linux-Insides? In simple terms, Linux-Insides is a “living note” that dissects the internal implementation of the Linux kernel. It is not a rigid document like the official manuals, but a series of articles written by the author 0xAX based on his own learning notes, complete with source code analysis, illustrations, assembly mini-experiments, and … Read more
