It includes some minor bugfixes and code cleanups. we are looking forward to your suggestions and we are highly interested in a discussion. In the next step we will port the patch to the current plugsched version and split the patch in a plugsched part and a dynsched part. The "dynsched" project aims switching the CPU scheduler at runtime. Its based upon the "plugsched" patch by Peter Williams (http://cpuse.sourceforge.net/). Increments to plugsched especially a kthread, wich switchs between different schedulers, in sched.c and a proc user interface. Following scheduler implementations are currently supported: * ingosched * nicksched * staircase There are some missing functions like converting task_struct between the schedulers. First tests on kernel 2.6.13.5 and 2.6.13.4 were successful. The spa based schedulers (such as spa_no_frills, zaphod etc) are not yet supported. I hope they will be finished soon, just as SMP support. There is an alpha patch available at project site - https://sourceforge.net/projects/dynsched Using the procfs you can switch between the linux standard scheduler (ingosched), nicksched and staircase schedulers by simply issuing: echo "name_of_the_scheduler" > /proc/dynsched There have been successful tests to switch the cpu scheduler while running a fully loaded Linux system, running a KDE Desktop with a lot of applications.
