CXL Poison Injection Merged into Linux 6.18: A Reliability Testing Tool for Persistent Memory Devices

by

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
