Project C announcement
BMQ scheduler has been development for more than one year. And it has accomplished the ambition when it was setup to be. As a simple scheduler, BMQ is now stable for several kernel release and less feature is added from release to release. It is now in maintenance mode.
When searching for idea about cpu scheduling, PDS, which has been exiled since BMQ, is still the most potential one, and the one most close to BMQ(in code level and performance level). Several very early improvement idea has been drafted after the reviewing of the latest PDS(kernel 5.0). So, PDS will be picked up again, and it is going to share same code base of BMQ. That comes Project C.
Project C ambitions
1. Based on BMQ code base, provide common alternative cpu scheduler code for linux kernel.
2. Provide single patch set for BMQ and PDS, switch at kernel configuration.
3. Maintenance BMQ
4. Continuous improvement on PDS till it enter maintenance mode.
Here is the recent Project C planing in the incoming kernel release cycle
5.7 Refactor BMQ into Project C infrastructure.
5.8 Recreate PDS based on Project C code base.
5.9 PDS beta.
5.10 PDS official release.
5.11 PDS continuous improvement.
Project C has no deadline defined, but may last for a year.
And the last thing, C for "Cross".
