LinuxCon North America/CloudOpen North America

With raising popularity of Linux on mobile devices the shortcomings of the default kernel memory management policies become more and more visible. The combination of limited physical memory and lack of swap device brings a challenge in the most efficient use of the available resources. This presentation will give an overview of the current state of improvements (i.e. memory control groups, per-process/group reclaim, memory compression) to the Linux memory management subsystem that together with the cooperating user-space components allow more custom control of the memory available in the system. The usage examples of specific features will be based on Tizen operating system.

This talk is intented mainly at kernel and distribution developers wishing to improve Linux memory management but it may be interesting to whoever would like to know more about the topic.
