PDS 0.98g is released with the following changes
1. Fix rq->online is default false for cpu 0, issue reported by Manuel.
2. Remove update_rq_clock() in hrtick(), it's a minor enhancement.
This is a bug fix/enhancement release. After bug fixes for the new features in the recent releases, I have done a kernel compilation benchmark in 4.14. The results are as expected, but it also indicate that the overhead under high workload is larger than CFS. So, reduce scheduling/balance/migration overhead will the next feature in the todo list. But don't expect such features will be coming soon, as current PDS is stable, I'll tend to slow down and do more research before rolling out new features.
One more thing, current release of PDS is running well on raspberry pi, you can have a try if you own a raspberry pi soc.
Anyway, enjoy PDS 0.98g for
v4.14 kernel, :)
