This module introduces the fundamentals of Linux memory management, including virtual and physical address spaces, address translation, and kernel versus user memory layouts. Learners will gain practical skills in interpreting process memory maps, understanding key kernel data structures, and exploring security features like KASLR. The module also covers tools and techniques for examining memory organization on both 32-bit and 64-bit systems.

This module introduces the fundamentals of kernel memory allocation for module authors, focusing on the Page Allocator and Slab Allocator mechanisms in the Linux kernel. Learners will explore allocation strategies, relevant APIs, and best practices for efficient and safe memory management in kernel modules. Practical demonstrations and troubleshooting tips are included to reinforce key concepts.

This module delves into advanced kernel memory allocation techniques, including the use of custom slab caches, the vmalloc() API, and memory management features like the OOM killer and VM overcommit policies. Learners will explore practical tools and strategies for efficient memory allocation, monitoring, and troubleshooting within the Linux kernel environment. The module also introduces recent kernel features such as DAMON and multi-generational LRU lists.

This module introduces the fundamentals of Linux CPU scheduling, exploring POSIX scheduling policies, multicore task management, and the internal mechanisms of the scheduler. Learners will gain hands-on experience with command-line tools for analyzing scheduling behavior and visualizing task flow. Key concepts such as preemption, scheduling classes, and kernel data structures are also covered to deepen understanding of how modern schedulers operate.

This module delves into advanced Linux CPU scheduling concepts, including CPU affinity, scheduling policies, and the use of cgroups for resource management. Learners will gain hands-on experience with system calls, utilities, and systemd to optimize process performance and resource allocation. The module also introduces real-time Linux considerations and practical techniques for configuring CPU constraints.
