Hi all
Just purchased set CPU for nexus s.
Was wondering what would be the best settings for my NS?
Thanks

There is no "best settings"
It varies with your setup. Personally when I was using setcpu (using cm7 now so i dont need it). I had it setup w/ stock clocks (1000/100) with smartass governor. That was it. From what I read with smartass governor you don't need additional profiles
Thanks NYYfan,
For your response,
Heeter
I don't have smartass in the available governors...
Only : interactive, conservative, userspace, powersave, ondemand and performance.
Which one correspond to smartass?
Where can i found the governors description?

Smartass governor is available when you flash a compatible kernel that supports that governor.
Most people (including myself) use Netarchy's 1.3.4 which features the smartass governor. You can google about that governor to find out what its about.
Who knows the difference and can explain what the lagfree, interactive, ondemand and userspace CPU Governors are? Please, no guessing, I can do that too. If you know what some of these are, share the info, please. Thanks.
Google or read set CPU readme ....

This link describes lagfree. Only God knows why I didn't have the sense to confer with professor Google.

Hey,
I decided to mirror your kernel:

Download speed is pretty good.
Let me know if you'd like me to remove it.

Not that I can think of, don't have much time to be posting but all I can think of is the bootanimation.zip needs to be named /system/media/sanim.zip

Sweet, may have to try this, faux is sucking out for me.
Defaulted to SIO scheduler for me. Changed ala system tuner to NOOP. What is it undervolted by as the default?

Thanks for the new Kernel!
Just curious, but does it take a lot of work to add overclocking ability to kernels?

sio is better than noop
all I can say to this kernel.... is wow. I'm in love with the lionheart governor. Haven't got around to trying the rest but its sooo smoooth. Underclocked to 1.242 and its still running nice. I was also able to underclock and additional -50mV and running stable. Sorry faux, I've turned traitor

Why? I read about all of them, but can you explain? This is what i've found
SIO
Simple I/O scheduler aims to keep minimum overhead to achieve low latency to serve I/O requests. No priority quesues concepts, but only basic merging. Sio is a mix between noop & deadline. No reordering or sorting of requests.
Advantages:
Simple, so reliable.
Minimized starvation of requests.
Disadvantages:
Slow random-read speeds on flash drives, compared to other schedulers.
Sequential-read speeds on flash drives also not so good.
Cm7 compatible?

Because it has minimal overhead and doesn't do any requeueing, only processing in order, which most of the time is good in our case as we want to give the task in use priority, which sio does
This kernel is awesome! I love it.

Literally lol...my processor goes crazy and reaches my temp threshold on SetCPU. I'm running Mik's 2.0, and i have minimum apps running at startup. i even log out of FB when i open the app. does anyone else have this issue where this app heats up your phone, and what did you do to counter it? Any info helps. Thanks in advance!
Whats your cpu speed set at? What i/o scheduler and what governor you using?

my cpu speed is only set at max 902MHz for the normal profile, and i'm using the x99 GB kernel. i don't believe i'm using any i/o schedulers :/ i only use setcpu to govern the cpu. i just had to research i/o scheduling when you mentioned it...wanna school me on what that is used for and if it would remedy my cpu heating up lol? thanks for the reply.
No frills cpu or antutu has a cpu control app available free on the market. Both allow you to change your governor and i/o scheduler... Ill get ya a good link about i/o scheds...

i actually just got done reading that same link lol! thanks for the advice on the app to use, couldn't find one. so with my specific issue here, what is your preference for the i/o schedule to use?
Your phone will tell you more about preference than I can... I personally use vr i/o scheduler and on demand governor...

thanks again man. i'll look into it a little more!
With x99percent kernel I use "cfq i/o" and ondemand set to 1.2 ghz max and 184 mhz min.
I'm on Sparks' at the moment, sio for the I/O, max: 1.4, min:384, using Antutu CPU
thanks for the suggestions! i downloaded the No-Frills app and set it to "cfq" and so far it has yet to reach the temps it did without the i/o scheduler. once again thanks for all the help!
Glad we could help... That's what we're here for.

Are governor's and schedulers the samething.If not what are schedulers used for?and what are they?arn't governors pretty much built into all new kernels?are schedulers built into kernels as well?If someone could please explain I would appreciate it.
