Diving into the kernel mitigations

This presentation delves into the kernel mitigations within the Linux kernel designed to counter hardware bugs, offering insights into major strategies and their implications. It also addresses the performance ramifications observed in real-world production environments and outlines the trade-offs developers face when operating kernels with mitigations enabled, particularly in low-level and assembly analysis scenarios where mitigations like retpoline can disrupt code readability.

Given the persistence of hardware bugs, this presentation aims to equip attendees with the knowledge needed to effectively manage them.

Through this comprehensive exploration, attendees will gain a deeper understanding of Linux kernel mitigations and their implications for both system performance and development workflows.
