Abstract
The limited built-in configurability of Linux can lead to expensive code size overhead when it is used in the embedded market. To overcome this problem, we propose the application of link-time compaction and specialization techniques that exploit the a priori. known, fixed run-time environment of many embedded systems. In experimental setups based on the ARM XScale and i386 platforms, the proposed techniques are able to reduce the kernel memory footprint with over 16 %. We also show how relatively simple additions to existing binary rewriters can implement the proposed techniques for a complex, very unconventional program such as the Linux kernel. Finally, we pinpoint an important code size growth problem when compaction and compression techniques are combined on the ARM platform.
