: Understanding the differences between monolithic and microkernels, and how Linux handles user-space vs. kernel-space transitions.
: Mastering atomic operations, spinlocks, mutexes, and Read-Copy-Update (RCU) to handle race conditions in a multi-processor (SMP) environment. linux kernel internals and development lfd420 pdf hot
: Detailed deep dives into the task_struct , process scheduling via the Completely Fair Scheduler (CFS) , and virtual memory management including paging and NUMA. and debug kernel code.
LFD420 is a high-intensity, four-day instructor-led course designed to provide a comprehensive look at how the Linux kernel is architected and how its internal algorithms function. It goes beyond theory, focusing on the practical ability to develop, modularize, and debug kernel code. linux kernel internals and development lfd420 pdf hot
