[Q] BFS and CFS, SBC and noSBC kernels? Do we have these for our SGS?

What is BFS and CFS, and what is SBC and noSBC kernels? Do we have one for our sgs? Just saw in one of the battery saving tips that SBC kernels MIGHT give more battery life so I got interested. Anyone has any ideas?

CFS and BFS are different task schedulers. I believe all SGS kernels currently use CFS (Completely Fair Scheduler) by default. It is the industry standard at the moment.
Some kernel designers are experimenting with a variant called BFS (Brain F*ck Scheduler) which some people claim gives better performance, but it seems to be somewhat unstable and some people claim it gives no benefit at all. I would expect most if not all SGS kernels to continue using CFS, at least as the default option.
SBC is a scheme called Superior Battery Charging which basically uses a trickle charging hack to override the safety feature that keeps the SGS battery from charging to 100 percent, allowing you to push a little more power into your phone. I would expect that this hack would decrease the life span of your battery and some people even claim it is flat out dangerous (exploding batteries and what not...not good). I don't know of any SBC kernels available for the i9000.

Wow, thanks for the quick info and reply! So i guess will have to settle with the CFS. BUT if there are SBC kernels for the i9000, i would be very much willing to try one - - already taking into consideration the risks you mentioned but afaik only if the battery temp reaching 80C that it will explode and before the phone reached that temp you'll already feel the heat and will either turn it off or get away from it Anyway, thanks for the additional info on these kernel types.

[KERNEL][AOSP] LorD ClockaN (lordmodUEv8.5-CFS-VIVO-2.0)

The new kernel by LorD ClockaN for AOSP(cyanogen and MIUI) roms is here.
http://www.multiupload.com/YQTRBBDO3B
http://www.4shared.com/zip/VC9M-tPU/lordmodUEv85-CFS-VIVO-20.html
This is 8.6b3 of his DHD kernel for vivo.
Please try it and post reviews which will help him to further work on incredible s kernels.
A big thanks to LorD ClockaN for his great kernels.
Governors explained: (Thanks to LorD ClockaN )
*interactive - Instead of sampling the cpu at a specified rate, the governor will scale the cpu frequency up when coming out of idle.When the cpu comes out of idle, a timer is configured to fire within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer fires then we assume the cpu is underpowered and ramp to MAX speed.
*smartass - Is an improved version of interactive governor.
*ondemand – Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see “up threshold” in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed.
*conservative – Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery.
*performance – Available in most kernels. It will keep the CPU running at the “max” set value at all times. This is a bit more efficient than simply setting “max” and “min” to the same value and using ondemand because the system will not waste resources scanning for CPU load.
*powersave – Available in some kernels. It will keep the CPU running at the “min” set value at all times.
*userspace – A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor.
*brazilianwax - Very agresive version of smartass.
*interactiveX - Tweaked Interactive governor by Imoseyon by adding more features like suspend/wake profile.
*ondemandX - Tweaked and ported from 2.6.38 base Ondemand governor by Imoseyon by adding more features like suspend/wake profile.
P.S: This kernel is not for Sense Roms !

this kernel for sence or cynagon or miui ?

aosp (cm7, miui). it says so on the first post.

Did a restor and reflashed the new v. 2.0 Kernel, but same problems as first time.
The strange thing is that test score with Quadrant is 3089 with both Kernels.

any changelog?

accidently im install to sence rom, this kernel accepted & working but i dont know others reflect like sms/call delay etc .... can someone test it!

Anyone else tried it? it is running fine on my miui rom. boot time was also good. couldn't find any bug in the bootanimation (maybe a slight lag in the animation).
Edit: felt a very slight lag while moving pics in the gallery.

Kernel is working fine.. Can't feel any difference between previous version and this.. But still Two Way call recording and in call audio boosts are missing.. Need the latter badly..
The only difference I feel better from Tiamat kernel is, this one does better fps in 3d and 2d animations..

I use this with CM nighlty 146 too.
booting is the same as v1.
but at governor "conservative" ,this version is much lag than V1.
For me ,V1 is faster responding than V2.
no other issue.

Welcome to the Thrillz kernel for LG Thrill 4G (may be compatible for O3D).
Standard disclaimer: You bork, your phone. I take no liability. K?
Includes OC to 1.2 native (no modules) and 100 MHz frequency.
cifs.ko module built in.
Conservative governor enabled.
init.d support native.
More to come.
V2 update includes:
Insecure boot
persistent root shell in adb
Removed 100 MHz frequency (caused more issues than it was worth)
Trying a 200 MHz frequency.
V3 includes:
Lock 200mhz when sleep (was set at 300, swapped due to removal of 300)
---Working on other improvements, may be a week or two due to cleanup of code and removal of non-4430 chaff---
V4
Updated frequencies (300, 600, 800, 1000, 1300)
Lower cpu voltages.
#Note, seems screen is eating more battery than CPU. Will investigate.#
Plan for V5
More governors, possible UV compatible with Xan's Voltage Control app.
If you have suggestions, ideas, please give me them.
I do plan on more governors (maybe smartass, interactive, ect....) more io schedulers (bfq, ect...) and anything else that comes my way.
Special thanks to those who have gone before me and helped my learn what I have: gtg465x, LinuxBozo, and Entropy512 for everything that I've learned from them in the Infuse 4G forums, Excaliburinhand for encouraging me to start my own kernel, CallMeAria, Urabewe, tylerwagler and gtg465x again for what they've done here before me... and to you for choosing this kernel (I know... Video game cheezy, but it's true. )
Git is below, it is under the wagler kernel git as it was what I forked and am pushing to. I decided it's time to get started with this.
And please remember, thanks button is good as is fueling my insanity. If you look at my Infusion kernels, I do recognize my "Insanity Crew." (and if you want to be kept in obscurity, I respect that as well. )

Good to see you guys pushin' the kernel movement forward, and sharing your work.
Good deal on getting that built in overclocking going as well. I've been running the kernel for the past day. I did notice an issue, though. Maybe it's just my phone... But the 300mhz OPP, is not being utilized.
I've attached some screenshots.

I was planning to mention that, will try to fix. (100-300 bug) on battery life, what governor are you running? I've found better life on conservative or on demand.

Usually I'm in hotplug or performance... My device has no service, so it doesn't see "normal use" like most. Most of the time it just sits and sleeps.
So, what I did yesterday, really because I wanted to see if you guys squashed the random reboots I've notice in my own playing with LG's kernel source... Had a fully charged phone, flashed your kernel, ran a few benchmarks, still had over 90%, and just let it sit in hotplug. got back to checking it out maybe 12 hours later, noticed the drain, checked setcpu, and that explained it for me. My phone normally would be 80% to 90% in 300mhz... But I don't think 100mhz is able to accomplish most tasks, so it's always popping out, even when it should be idle sleeping.
One thing for me is wireless tethering.. The device needs to be able to accomplish this in the background, and 300mhz even on a DroidX is able to accomplish this. 100mhz is a no go, though.
If you find it real difficult to get 300mhz functioning with 100mhz, I'd say chop the 100mhz out for now, and give us a bump, or atleast put out a 'high voltage' 1388000 mV(TI's kernel 3.0 number) top slot version of the kernel... The overclock module still works with your kernel, BTW... So, in combination with the voltage bump, those that are real speed freaks can push toward that 1300mhz mark with stability.
P.S. No random reboots, so that gets a big thumbs up!!!

I'm going to try and keep to 5 freqs, going to see if 200 works. If not 300 will be low end. Wanting to see if 1.4 or 1.5 is possible with proper voltage. (we should reach sgs II performance benches at that level. )

I think I got an issue. Starts to lagg when typing/texting. Maybe its the governor I used. I tried with both concervative and ondemand. Also hotplig too. Conservative had the least amount of lag but still noticeable. The other 2 were way too laggy. Unusable.

I believe that's due to the 100 MHz freq. I rebuilt later night without it and while I am typing this there is no lag for me. Re-uploading V2.

Anyone flashed this can comment on battery life and any issues?

Haven't had it long enough for battery use, but it made slim doomed speedier.

Flashed it. So far no lag. Battery life kinda iffy. But it's a brand new battery. I'll clear the stats and see how battery life is then.

No issues, phone feels really fast, more batt drain though. I like it.

[KERNEL][AOSP][ICS] invisiblek-ics

New thread to house the custom kernel built with linaro's gcc 4.7.1 toolchain
This *should* work with any AOSP ics rom.
Just because this kernel is built with the linaro toolchain it does not mean the rom needs to be compiled in a certain way.
Download here: http://tinyw.in/gnOy
I'll add more details when i have some more time.

Good question. This *should* work with any ics rom.

I tested this out last night (been running mamarley's kernel) and I ended up switching back for two reasons: first, this doesn't appear to have the 128MHz CPU speed - I'm not sure if that's intentional or not. And secondly, my phone apparently couldn't handle this kernel on 1113MHz - I got lots of FCs. And the rating on Nenamark was essentially the same as my baseline on other kernels.
Just some observations - and your mileage may vary! I really appreciate the fact that this is even being worked on, invisiblek.
EDIT: Totally meant AnTuTu, not Nenamark.

Great to hear feedback. Thats all im looking for here really.. It doesnt have 128mhz because its the same voltage as 245 hence no real benefit to having it. Plus some devices are unstable there. I never overclock but i can look at the voltages and maybe get 1113 stable

I can say it works on the new ICS TW rom, drains kinda fast although I think its rom related only.
I had only one reboot, got a freeze and then 10 seconds later a reboot. Its the only one I've had since reapplying new settings.
On freeze I was running SAv2 1113 Max/245 Min.
I have now lowered it to 998 and its running fine on that rom.
Other than that, its amazing.

[KERNEL] Gamma Custom Kernel XT890 (Version 6.0.2, Linux 3.0.101+)

DESCRIPTION
So this is a cooked RazR i boot.img that contains a custom compiled Kernel for our device, it was patched to be kept up to date and has some changes to help on battery savings, plus some cpu-freq drivers which which help our device a lot.
InteractiveX2 CPU Governor -- Like Interactive, and fine tweaked to only jump to 1.8 GHz on lighter/faster load increases, comes with a screen-off profile to lock down the frequency and offlinining of the rest of the CPU's defined as non-boot -- being an SMT processor this makes it easier to get the phone to deep sleep even when it wakes up to do something by reducing the complexity of the system.
Conservative CPU Governor -- Similar to ondemand. However, before the governor takes this lower frequency and slower clocked in the upper area, which has positive effects on the battery life.
Ondemand CPU Governor (Re)added -- it was originaly on ICS stock Kernel, it adjusts the CPU frequency to the given requirements, however quickly clocked in the upper frequency range to ensure smooth working.
Performance CPU Governor -- this will clock the CPU frequency to the top, not recommended for prolonged use.
SimpleIO Scheduler (Default) -- is a mixture of Noop & Deadline and one of my favorites.
V(R) IO Scheduler -- is the best scheduler for benchmarks, in everyday use can become unstable.
BFQ IO Scheduler -- A proportional-share storage-I/O scheduler that also supports hierarchical scheduling with a cgroups interface with Low latency and high throughput.
ROW IO Scheduler -- This one is very battery friendly and now my favorite for mobile decies by it's simplicity and responsiveness.
It is known to work on stock & stock based ROM's (such as this one where it is included).
As of other differences there are a lot of GNU compiler flags optimizations, by knowing that the compiler wouldn't know some vital information since it is a remote target different than from where I am compiling so I decided to be pretty explicit.

NOTES
For more information regarding governors, schedulers, modules, etc visit this thread by forum member droidphile.
This is my personal experience to other people on compiler flags, if you guys want to try -O3 straight ahead you will face issues on battery readings unless you remove the -ftree-vectorize flags on the battery modules that get compiled.
[IMPORTANT] For changing the CPU governor please use No-frills CPU Control, Since other apps such as SetCPU and AnTuTu CPU Master both only change CPU0 and may cause conflicts.
INSTRUCTIONS
You MUST be unlocked, and to take full advantage of other modules it is recommend to be rooted.
I will put something more descriptive here, but you can flash it with fastboot by doing: fastboot -i 8888 flash boot <boot.img>.
THANKS TO OTHERS
First of all thanks to Matorola/Intel for putting the main source and for Turl on giving me some info when unpacking/packing the boot images. Also to mattlgroff for the tutorial on unlocking the phone, more thanks to imoseyon and Mike Chan for providing the interactiveX2 source code and changes, it it is now my favorite CPU governor and also to HSD-Pilot for posting this originally on another forum -- I based my formatting from his post.

So is this kernel designed for speed or battery life, or a mixture of both?
Also will this work on the 91.2.26001 JB.EU rom?

By default for a mixture of both. But can be further chose different governors and parameters of the governors for different choices for the user. You can for example choose conservative governor and get more battery life and less performance.
And yes It can be used on that ROM. :good:

It works on jelly bean alright... but with this I'm missing the features of the Arman AIO boot v4 and I just can't live without it...

Damn, ok and thanks! ... so InteractiveX is not functional yet sounds like it must have something to do with the early suspend portion -- will eventually fix it. Good thing is that smartassV2 works flawless!

Nice work on the governors!
I remembered some governor benchmarks I read a while ago on this forum, and I thought you might be interested in it:
[REF][GUIDE] Battery Saving Governor Benchmarks
Some interesting quotes from the above thread:
the difference between the best (smartassV2) and worst drain (lazy) is 0.05mA (a tiny amount)
Click to expand...
Click to collapse
choosing SmartassV2 over Lazy would prevent about 600mA being wasted in one hour. To put this in context, that is enough to power your screen for 3 seconds (assuming a drain of 200mA).

Furthermore, I remember another thread (which I have not found), which showed that governors which did not jump straight to the highest frequency could actually negatively impact the battery life. The reason behind it is that CPU usage is only a fraction of the battery drain, and having a slower CPU means applications have to spend longer in active state, thereby also causing other components battery drain over a longer period of time. The display is the biggest battery eater, followed by the radios.
Basically, what I trying to say, is (most) governors have no perceptible impact on battery life, and I believe users who report otherwise suffer from the placebo effect. So I think focusing on a stable default governor which gives a smooth lag free experience is the way to go.

I agree for the most part but that really depends a lot on the type of processor and SoC capabilities, for phones like us I focused on the tweaked smartassV2 further to get it to ramp up and down faster, and it is noticeable smoother. , good battery life since it ramps down better than the on-demand or interactive governors here!
SmartassV2 was the winner on our testing too so we left that one . I just wanted to get InteractiveX working on it for future flexibility and the days that I messed up with SavagedZen it was just an experiment as I had never tried it before -- the results was that I did not like it a lot or I ported it wrong! haha

Friend'm using interactiveX governor since yesterday, andthe results seem to be good and had no lagg dabateria useful life is good (since I am a hard-user).
but honestly the samatassV2 is better, it seems that runs smoother on my device!
but just wanted to note that the InteractiveX is working!
sorry for bad english
