Linux-mm.org is a wiki for documenting how memory management works and for coordinating new memory management development projects. Please help editing this wiki. Thank you.

Documentation

• ["LinuxMMDocumentation"] contains information on how to tweak the Linux kernel memory management subsystem.
• ["LinuxMMInternals"] explains how some of the Linux kernel memory management works.

Projects

Some of the more active current Linux memory management projects are:

• CompressedCaching ([http://linuxcompressed.sourceforge.net/ Project Home Page]) and compressed swap. Reduce I/O by keeping more data in memory. (Please do not modify project homepage link).

• AdvancedPageReplacement The time needed to swap a single program into memory is ever increasing, so page replacement is becoming more and more important.

• NetworkStorageDeadlock - storage over network has a deadlock problem, where it can take memory to free memory.

• PageTrace - a kernel patch and tool to analyze memory access patterns.

• HugePages - Improving the availability and usability of huge pages
