Introduction to Memory Management in Linux

Explore the fundamentals of memory management in Linux through this comprehensive 51-minute video presentation by Matt Porter from Konsulko. Delve into the intricacies of virtual memory spaces and mappings used in the Linux kernel, understanding their implementation and differences from user space memory. Learn about hardware components like the memory-management unit (MMU) and translation lookaside buffer (TLB), as well as software concepts such as kernel page tables. Gain insights into user space concepts including growable stacks, memory paging, memory mapping, page faults, and exceptions. Discover the speaker's extensive background in Linux-related projects and his current work on GPGPU and eBPF hacks. Follow along with topics ranging from single address space limitations to lazy allocation and high-level implementation of page tables in this informative Linux Foundation presentation.
