Memory Management Bits in Arch

Linux Plumbers Conference via YouTube

Overview

Explore memory management in Linux architecture-specific code through this Linux Plumbers Conference talk. Dive into the similarities and duplications across different architectures, including page table allocation, early memory allocation, and initialization routines. Learn about the challenges of factoring out common code and refining the architecture-memory management interface. Discover potential improvements in areas such as per-CPU initialization, memory topology handling, crash kernel reservation, and vDSO mapping. Gain insights into cleaning up redundant code, streamlining page management, and addressing architecture-specific memory models and callbacks. Examine topics like flat memory handling, reservations, and page table management, with a focus on x86 architecture.
