Kolivas Pushes New Kernel Responsiveness Patches
Written by Michael Larabel in Linux Kernel on 26 February 2010 at 07:37 AM EST. 69 Comments
Con Kolivas had stopped working on the Linux kernel for two years after he became fed up with the kernel development community, but last year he made a return by introducing the BFS scheduler. The BFS scheduler for the Linux kernel is quite simple in design compared to other schedulers, but it performed fairly well on desktop systems. Due to Con's past frustrations, he has no intentions of mainlining the Brain Fuck Scheduler, but he has now offered up another batch of patches.

Kolivas has released a new set of patches this morning that are "designed to improve system responsiveness and interactivity with specific emphasis on the desktop." There are 13 patches he has made available that can be applied against the freshly released Linux 2.6.33 kernel. One of the patches is BFS, another changes the default timer frequency to 1000Hz, another adds new values that allows the timer frequency to be upped to 10,000Hz, and various other changes.

While Con Kolivas is not likely trying to get these patches pushed into the Linux 2.6.34 kernel, he has published this to the Linux kernel mailing list. His patches can be found in the 2.6.33-ck1 directory.
