Kernel Question: Havs vs. noHavs and CFS vs. BFS

[cloak.n.dagger]

I'm trying to expand my knowledge of Kernerls so that I can understand their benefits/weaknesses. Two things that I haven't seen that realy haven't been explained are Havs/NoHavs and CFS/BFS. I have no clue on the Havs/NoHavs and the CFS/BFS has something to do with schedulers, but this means nothing to me. Looking for a quick and dirty explanation, nothing in depth. Thanks! AC and it's members rock!

Havs = hyper active voltage scaling, basically changes the voltage of you phone in order to have sweet battery life. Some phones don't handle it well though.
cfs = completely fair scheduler, its less agressive than bfs but generally more smoother. The stock HTC kernel uses cfs.
Bfs = brain .... scheduler (Google the real name) , its more agrssive when terminating tasks, generally gives better battery life. Sometimes its less smooth, depends on the phone.

Anything else

Thanks igots! When you say smooth, I assume you are refrerring to fps and scrolling?

Not to bump this thread, but I found some more detailed information for anyone who may be interested in reading up on this...

Smooth as in, jittery sometimes, and other little quirks that arent 100% buttery.
