Finally, a comprehensive guide to the Linux VM!
VM's behavior affects every Linux kernel subsystem and dramatically impacts overall performance. But until now, there was only one way to understand VM: study the poorly documented source one line at a time. Now there's an easier, faster alternative. This book describes VM in unprecedented detail, presenting both theoretical foundations and a line-by-line source code commentary. It systematically covers everything from physical memory description to out-of-memory management. Coverage includes:
Linux VM 2.4 architecture in depth-with diagrams and call graphs
Physical memory description, page tables, address spaces, and memory allocation
High memory, swapping, shared memory, and much more
Expert guidance for analyzing the code of any open source project
New Linux 2.6 kernel features in every chapter
Well organized and superbly written, Understanding the Linux Virtual Memory Manager will be indispensable to every kernel programmer and researcher.
Complete VM Learning Lab! Contains the author's new toolkit for exploring VM, including a browsable version of kernel source, CodeViz call graph generator; and VMRegress for analyzing and benchmarking VM. Also includes all code commentary in HTML, PDF, and plain text formats.
