CFS kernels have been known to be more consistent and stable than BFS kernels. Not to say that BFS kernels aren't stable, it's just that they have been known to have some slowdowns and whatnot, but overall, BFS kernels are supposed to be faster. They score higher on Quadrant and stuff.
What's better CFS or BFS?

At the top of this very subforum is a sticky called misconceptions and info. You could have read that instead making another thread about it. Is it really that hard to search or view the stickys?
We cant tell which one your phone will like better. Try both. If there was clearly one better, nobody would use the other :shrugs:

which is better...
Ford or Chevy
Colgate or Crest
Mr Pibb or Dr Pepper
Linux or BSD
etc
download both a CFS and BFS kernel.
make a nandroid
i wipe my cache and dalvik everytime i flash a rom or kernel
flash one of the kernels..run it for 2 days
make a nandroid
flash the other kernel..run it for 2 days
if you find that your phone prefers one over the other...then you have your answer.
my device seems to prefer the BFS when on Snap but the CFS when on King...explain that one. lol
I understand the op is looking for info but dam . The info is pinned at the top I think the q&a forum should be renamed chasper's play house

From what I understand both are task schedulers : components in the kernel that determine what process gets to run on the cpu at what time slices. Remember only one process can be run on a physical CPU core at any given time. In order to support multiple processes simultaneously the OS ( linux in this case ) uses these schedulers to share the CPU core among the multiple processes.
CFS refers to Completely Fair Scheduler and BFS refers to Brain **** Scheduler.
BFS was written to radically simplify the approach to task scheduling and its goal is to improve UI responsiveness while implementing a simple basic design. Based on device usage one scheduler might perform better than the other one.

While I agree with what you said:
http://www.google.com/#sclient=psy&...=f&oq=&pbx=1&bav=on.2,or.&fp=89e96c95c947f3f0
It really is not that hard. If you research this and then have a specific question about CFS/BFS, then OK....come in here and ask it. Example: If I go into one of my Mustang forums and ask: "What's the difference between a supercharger and a turbo?" then I'm going to get my ass handed to me. It's like every time I see a "What's the difference between Sense and AOSP?" thread, it makes me sick.
Where I agree with you, however, is to not go in the thread and be a ****. If you don't want to help, then don't go into the thread bashing someone. If no one answers, then they will have to do what they should have done from the beginning.......search.
Hey Guys,
I didn`t find one, so I would like to request a OC-Kernel for Froyo.
The reason I stick with Eclair is the OC-Kernel.
I like to tweak my phone in every way I can, even going beyond the "typical" 1,2GHz of the 2.1 OC-Kernel would be great.
Voltage tweaking Options (up as well as down) would also be great.
I know every thing of these is a high risk for the Phone, but I want to take it.
Maybe it is possible to add some or even better ALL functions of the other tweaking Kernels into this one, such as the optimized Kernel from laststufo or a lagfix, depending on what is the best available at the moment.
I myself can not afford a bounty for this at the moment, sorry for that.
But maybe someone who is also interested in this wants to put a little Bounty in.

You didn't try hard enough.
Maybe, just tried Google and the Forumsearch, both with zero results. Sry if there is already one. But I don`t think, even if there is one, it would integrate the Memory-Mod and all of the other tweaks or a lagfix (which most of the time also needs another Kernel).
And I don't think there is even one Kernel which lets me raise the Voltage of the CPU.
Maybe now someone wants to do this? Or teach me how to do this?

Why would you want to OverVolt?
it might be a bit rhetorical but...
why are you asking that question then?
because if the reason is good, then i may want to overvolt. i dont have the knowledge currently to understand . so this might be rhetorical, but " why are you a Mod and an asshole to someone seeking knowledge?"
simply because your question was not properly formed, instead it was stating the obvious
it'd have made more sense asking "when should you overvolt?" or "what do you gain by overvolting?"
you ask the proper question you'll get the proper answer, you ask crappy question you'll get crappy answer, as simple as that
O.k. ill play. I know you know the answer too so please don't disappeared now that I'm being g compliant with your request.
What would I gain by overvolting? I'm currently running Faux 007 kernel. I understand that undervolting should theoretically increase battery life, although I have been unable to see any difference in my tests. Would overvolting improve anything? Couldn't I harm something by overvolting? Any knowledge about this subject would be most helpful. Thank you

Completely unnecessary dude. You knew what he was asking. That attitude is exactly whats wrong with this forum. To answer your question OP, overvolting is mostly used for when trying to overclock to a high level. At least thats the way it was explained in a kernel thread in the vibrant forum.
Thanks Bro.....I don't know too much and read this forum daily trying to learn. Then a mod makes me feel Like a douche . But again thanks for your answer

no i don't, not until he clarified what he was really after
that's why i did said it was rhetorical
as the original question pretty much stated the obvious Why would you want to OverVolt? as in Overvolting, that's a big no no, it's common sense, under normal circumstances or default of any electronic devices, that will cause harm.
however if you do ignore the fact of such action will eventually kill the device, but you still opt to go for it, then the only logical reason is to gain more power, which is usually associated with OverClocking, some OC steps can not be archived without adding more power, that's where the extra push of the voltage comes into play

so in a sense OverVolting is only required under specific circumstances which are directly disproportional to the health of your device, but will grand you crazy speed & power in exchange for a shortened life span
His question was pretty clear. Ive read your responses on other posts, and your an intelligent person. Not sure why you wanted to respond in the manner in which you did. Just own up that you were being a jerk and lets all move on.
I'm thankful for the information either way. The thing that shocks me the most is that guy is a mod!!! That's a joke. Seriously to act like that and to be the one who judges others is why this site is under fire. I'm a noob , I don't know much about android but I do know attitude and a jackass when I see it.
Before i begin let me say I do appreciate all the devs here....but I want to know if what cobraboy85 brought up about ktoonsez and faux kernel really running at higher/ lower mHz than they are letting us know? Reason being is I love his 747 kernels but would never knowingly run my phone at such a high MHz. I personally feel if we are knowingly be miss lead on what the kernel is OCing our phones to it should be fixed. I wouldn't want to fry my phone from being miss lead. No disrespect to ktoonsez or faux just want an honest answer and thoughts. Thx.
Please don't start a flame war, just want some answers.

Whatever the case may be, it is vitally important to be able to trust the source of any kernel you use.
Can you? Probably not. I mean, who has the oversight here? Unless you really know what you're doing.. and let's face it, most users don't - they just install some kernel because another user said "use so-and-so's kernel, it's the best!"
There is waaay more to be concerned about when it comes to kernels than the clock speed (not to take away from those concerns, they are also valid, just not a major security risk).
I never use custom kernels. Just no way for me to tell what's really going on under the hood. Think about it.. call recording, statistical/data stealing such as Carrier IQ.. those sort of things tend to be implemented at the kernel level because
a. they have complete access to the entire system
and
b. it's undetectable to the average consumer, and even some of the most savvy individuals.
Not to say any Dev named here or otherwise is dishonest. I have no idea. But to act like we should just shrug our shoulders and "hope for the best" is idiocy.
If it were me, and I were the Dev, I think I would have moved very quickly to put any misinformation to rest and explain.
But I'm not a Dev
I for one am also interested in this. I am using ktoonsez's KT747 kernel because it integrates faux sound which REALLY improves the sound experience. However, my SGS3 is brand new and I paid quite a bit of hard earned $$$ for it, so I am not really interested in OC'ing it just yet until I'm ready.
I'm no developer but I know in Ktweaker there is an option to enable & disable overclocking steps. I have them disabled. While disabled, CPU Spy shows 6 different "1512" frequencies being unused. When enabled, CPU Spy shows the 6 steps above 1512.
It's probably just the way he coded his kernel to be able to enable/disable CPU steps (because I haven't even seen a kernel before where you could enable/disable overclocking steps before). I think there is way too much being made of this.
They aren't criminals or some masterminds bent on world destruction...I feel like if you had just brought it up as a question in faux or ktoonsez development thread like "hey i noticed this in the code does that really mean it's not clocked at what it says its clocked at?" nicely they would have responded to it with an explanation. They are genuinely helpful and answer everyone's questions no matter how rudimentary or repeated they may be.
And I'd bet money on it being a coding quirk, like a shortcut or workaround or a creative way to give us, who remember do not pay these guys a cent, awesome software for our phones. I think Google or Samsung should pay them serious money to develop kernels for them. They should be rich men with the talents they have.
Ktoonsez, faux, if you read this, I'm behind you guys 100%. Don't let some witchunters and attention whores bring you down. My battery life doubled with Ktoonsez's kernel and I thank him for his hard work. Thank you both so much for your work!
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
No ones on a witch hunt and I'm far from an attention whore....just want to know when I set my CPU controller to a certain frequency that's what it set to. I'm running ktoonsez kernel right now and really appreciate all the dev here in our forums.

Still don't understand why anyone would want to overclock this phone. There is nothing to be gained, except higher benchmarks scores.
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
This thread is complete fail. No one deserves any kind of answer for anything. Both of these devs do this for free. Both do it in their spare time. Both create amazing kernels that I've ran on my phone flawlessly for months.
Even if the clock speeds were inaccurate, who cares? Don't use it. Move on. Whatever. Why so much drama on a development site? These threads are 100 percent disrespectful and if I was smart enough to do what these guys do I would stop sharing my work.

I didn't mean you in I actually meant cobraboy85. (sorry! ) It's indeed a legitimate concern, but the way cobraboy85 went about figuring it out was just plain disrespectful.
When somebody finds something that doesn't make sense or seems wrong, the first step is to privately contact the person, even politely on the development thread, about what they find.
If the develpoer tries to cover something up or hide guilt or dodge questions, they bring it up to an admin or another developer to get a second opinion.
If they determine with other people (with experience) in agreement that something wrong is going on, and administration is unable/unwilling to do something about it, only then do you post something like he did.
Instead he just posts a thread and makes accusations. I think that's cowardly and rude and wrong. Now everyone is wondering what's going on and now the reputations of two developers are being dragged through the dirt for no reason. It's just ridiculous to me.
Re: Is the issues cobraboy85 brought up about some kernels in the closed thread true?
The OP is asking a simple question. He is not accusing the developers of anything. If you don't have the answer, feel free to move along. No need for argument. If you really feel that a thread is out of line, use the report button and let the mods decide.

I have this to say. I absolutely do not stand behind forum trolls who are out to make names for themselves, and cause trouble for those who spend of their free time to make our devices better and free from the grips of the garbage software they are released with.
At the same time, I also will not blindly (note the word blindly) follow what developers do and say. This is the reason why we have things like nightlies for CM; so that code is constantly reviewed to ensure they are not only clean, but optimal.
Having said that, I absolutely TRUST 100% more the word of a developer than a troll. And as for ktoonsez and faux, all I know is that their work has made a real-life difference for me. The sound on the SGS3 out of the box is TRASH. I'm a musician and I'm a pure stickler for sound quality; believe me when I say that their work has made the sound 200% better than it was. And for that, I am grateful.
Although it would be nice for the devs to pitch in this thread and just let us know what's up (they really don't have to), I am apt to believe the cobraboy85 is just a whole lot of hot air. If the kernels were indeed overclocking like he claims, my phone would not get better battery life than with stock; it would get magnitudes worse, because the ROI is just not there for 300Mhz more.
So all in all, either our phones are magical enough to stay with the same battery life AND enhancements with these custom kernels, or someone is just looking to make a name for themselves.

Just to add my 2 cents here...does not all CPU checking apps report 1512Mhz when you set to no overclocking? Kernel source has ALWAYS been freely available as per GPL so no one here on this site is deceiving anyone. Also I have never had a problem with kernel devs answering my questions. If you post a question and in general no less, do you really think the developer is going to see it? As pointed out earlier, a respectful post in the kernel thread would have gotten you the same answer I got from KT last night...no...when set to 1512 your phone runs at 1512.

Sounds like a great question sir. Hopefully someone can tell us how the apps measure speed and if there is a true test app. I do know that Samsung hugely underclocks these phones to give a compromise between battery life and speed. Personal experience is that I get better battery life on the Sprint KT TW kernel than I do on stock. That wouldn't happen if I was at 1.8Ghz instead of 1.5.

Ok guys, kenny brought this and the SUPER rude thread to my attention so I am responding. Let me start off by saying I NEVER knowingly mislead anyone and sorry a bunch of you feel I jipped and mislead you!
The table the original thread posted about is only about 1 tenth of the code. Here is snippit of code that regulates the table size (again only a little piece)
Code:
int get_the_freq_table(int cnt, int steps[]) {
if (acpu_freq_tbl == NULL)
return 0;
int real_cnt=FREQ_STEPS;
int i= 0;
//if (isenable_oc == 0)
// real_cnt = real_cnt - FREQ_TABLE_SIZE_OFFSET;
for (i = 0; i < real_cnt; i++) {
steps[i] = acpu_freq_tbl[i+1].speed.khz;
}
return real_cnt;
}
Important piece here is FREQ_STEPS = 24 thus not using the other steps which are mearly placeholders for people that are gonna use the OC steps.
As far as the math on the OC, that is my bad for not checking the math. To be totally honest, we were all new to the QCOM chipset back in June/July of last year and kanged from the same XDA dev, not gonna put blame on that person. So in conclusion, yes the 2106mhz after I examined it after seeing that post was indeed lower due to following the original incorrect math. Also it turns out the Sammy original 384 Mhz is not even possible when you try the following simple math:
384,000 / 27,000 = 14.2222222222222222222222
So again, let me reiterate, I NEVER knowly lied to say its going faster or going faster than it is telling you and sorry for the confusion on the OC :good:
Hardly an exciting subject, though just 'upgraded' my G Grand to 4.2.2., so far not really into the small changes, and might reflash 4.1.2.. Will see how the battery life compares, doubt there's any difference though, missing some off the user settings and stuff.
What do you guys think? If there is a link regarding this topic, or any knowledge on the pros/cons 412 vs 422 thanks in advance..... Maybe there is a link in this site with a subject already on this, so please leave a link..
Much thanks, and have a great week.....
My 2 cents worth for anyone thinking of going 422,are stay 412, though only flashed 422 today, so will give it a go for a week, and see....
