Introduction to Memory Management in Linux

Introduction to Memory Management in Linux - Matt Porter, Konsulko All modern non-microcontroller CPUs contain a memory management unit and utilize the concept of virtual memory. This presentation will describe the different types of virtual memory spaces and mappings used in the Linux kernel, the cases in which they are useful, how they are implemented in the kernel, and how they differ from user space memory. Concepts such as the hardware memory-management unit (MMU) and translation lookaside buffer (TLB) will be discussed, as well as software concepts like kernel page tables. User space concepts such as growable stacks, memory paging, memory mapping, page faults, exceptions, and other memory-related conditions will be covered as well.

Matt has contributed to a number of Linux related projects over his years of community involvement including the various part of the kernel, Debian, RapidIO, Beagleboard.org, and many others. Matt is currently working on GPGPU and eBPF hacks for Linux. Matt has spoken at previous Embedded Linux Conferences on the topics of userspace drivers, Android, Linux 6502 remote processors, kernel testing, and USB gadget configfs, and IoT frameworks.
