This is the Googlecode link of RIFS series. http://code.google.com/p/rifs-scheduler/
Here is the download link for RIFS.ES-v1-kernel3.4.x: http://rifs-scheduler.googlecode.com/files/RIFS.ES-v1-kernel3.4.x
The design of RIFS/ES:
First let me list out the 3 equations of SystemV scheduling.
0.cpu = cpu +1; 1.cpu = cpu/2; 2.priority = (cpu/2) + base level priority;
These 3 equations are used to determine the scheduling priority if a task. Here there is no any complex detection of interactive task(O(1) failed on desktop because of the complex detection). O(1) did a hard-coding and kerp focusing on how to detect a whether the task is an interactive task or not. CFS is good with its beautiful design. But in my opinion i think the sleeper feature will destroy the beautiful design.
RIFS-ES adopt the design of System V scheduler. It can be interactive. On my box everything is very smopth Chen [unhandled content-type:application/octet-stream] | |
