Key Features
1. a branch entitled "zen-tune" was added - this branch implements four tunable profiles, defaulting to desktop - only adjusts 4 things so far
-
Server Settings: dirty_ratio: 80, dirty_background_ratio: 1 --- BFS rr_interval and iso_cpu are left at default
-
Default Settings (nothing changed): dirty_ratio: 20, dirty_background_ratio: 10, *BFS ONLY* sched_iso_cpu: 70, rr_interval: 6
-
Desktop Settings (selected by default): dirt_ratio: 50, dirty_background_ratio: 20, *BFS ONLY* sched_iso_cpu: 25, rr_interval: 3
-
Custom Settings: Enables another menu which allows for each to be set manually - also has descriptions for each variable from the documentation
2. The "
classic-rcu" branch from zen.git was pulled into a new branch, but:
- The preempt rcu implementation is dropped totally
- The classic rcu implementation is changed to match the implementations of 2.6.33 tree rcu and tiny rcu, instead of 2.6.31 classic rcu
- Several compile errors have been fixed, probably due to one or both points mentioned above
- Classic RCU will probably replace tree_rcu in the default zen spot after this release (if no bug reports, will become default in zen2)
