Requesting an over clock kernel at 528 standard

Hi i have one of those phones that wont boot at 710 standard kernel and i was wondering if someone would post an overclockable kernel that defaults to the standard 528. Thanks in advance to any sort of help

What?? Just flash a ROM that isnt OC'd.

can't you just set OC widget to not start at boot? I know there's a setting that mentions load at boot.

I think what he wants is an OC kernel that is overclockable but because his phone can't handle 710 (which most OC kernels default to) he'd like to start at 528 and see what he can push it up to.

Why don't you just use a OC widget and set the clock speed there?

Probably because he can't get his phone to load in the first place?

i am experimenting with this exact thing let me know what rom you plan on useing and i will see if i can work it out for you.

my phone will boot with the standard clock then it will work fine when it boots i just get the endless bootloop with kernels starting at 710

yeah mine doest that as well i have tried several different roms. has your phone ever gotten hot while useing it?

Yes it has i think if i find a kernel that defaults to 528 and you can use over clock widget to over clock it will boot all im looking for is the old kernel that they used to over clock with

working on it is my first time with mixing and matching a kernal to a ramdisk.

I appreciate the help

Modified a boot image with the lower default speed is possible, but it's involved adding the default clock in the init.heroc.rc in the Ramdisk of the boot image. There are many ROMs in this forum each has each own ramdisk. If you can decompile your current boot image, you add the 2 lines below to your init.heroc.rc under #power management
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 245000
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 537600
-You can use this (read this and install on your system): http://forum.xda-developers.com/showthread.php?t=633246#
That is a tool to cook your own basic ROM or use it to decompile the boot image, edit the ramdisk, recompile and sign your own flash zip.

currently im using blue echo 2.1.3 i would like to try the new version of that but i cant boot with their default kernel i would like one that will work with that and maybe one that will work with some of the new roms out that default to 710 thati havent seen yet

obviously you failed to read the post. its all linux stuff, to run on windows you have to use cygwin. so yes it runs on a mac

Ok Blue echo is fresh based so this should do the trick!

LOL I see i named it 547, but default is
245760-537600
Be sure and nandroid. I also removed the "on_demand" tag, i have had a suspicion that it may cause a problem with some phones. If you want to use on demand scaling, or any mhz higher than 537.6 use SETCPU to change it.
EDIT: Please let me know the result.

[Q] About the ~200 line Linux kernel patch that does wonders

Hello, guys!
I guess most of you know about this "magic patch" that significantly boosts Linux speed. It's going to be merged in the 2.6.38 branch and it's shipping with Ubuntu Natty too. But this kernel patch can be applied to a previous kernel as well, just rebuilding it with this 224 magical lines of code.
What I wanted to know is if it's possibile to rebuild our kernels with this patch, if it is already, or if it's possibile but won't have significant boosts on Android devices.
You may read more about this on Phoronix. On the 2nd page there are video demos for lazy ones!

This has been discussed here twice &found not to help because we dont use harddisk.

Thank you, but can you please link the thread with this discussion? I can't seem to find it. Also, this patch regards CPU, not hard disks.

this patch will be officially introduced in the 2.6.38 kernel..
also, this kernel will have about 50% more speed increase, due to the 200 lines patch and another issue resolved after it .. in general the upcoming kernel will be blazingly fast !!
there is a script that tries to do the same as the patch for earlier kernels. which I use on my Ubuntu laptop, and yes major performance increase !!
I tried to apply it to my previous phone (HTC Hero), but didn't work. I also asked Cyanogen on his twitter, but didn't care to give me an answer..
finally I gave up, and decided to wait for the next Android version that will have the 2.6.38 in the future..

I'm using that script too on Maverick! I don't think there should be a significant increase in responsiveness if you apply it on high-end systems, but our SGS might benefit from it (as my old dual core system).
You say it didn't work on your Hero, but were there any errors in dmesg or you didn't find any significant change in speed?

dmesg should no difference. the script just showed a lot of errors.
I tried the "non-Ubuntu" version as described in Webupd8, but still similar errors.
I guess Android place the kernel differently from Linux desktops.

I might be mistaken, but SO kernel uses its. And haven't really noticed any difference with or without it.

please don't spread incorrect facts:
* the "automated per tty task groups" (or autogroup) patch - by using cgroups (in CFS - the cpu scheduler) and thus isolating several taks from each other, giving them dedicated slices of cpu power - allows the system to be more responsive under load if there is a kind of cpu hog (task producing much load)
* the speed increase is due to Nick Piggin's VFS changes and Andrea Arcangeli & Mel Gorman's Transparent Hugepages (THP) support (and of course lots of other changes)

that's correct: - "sched patch : automated per tty task groups (system more smooth and responsive) (v3(since 4_3) and v4(since 4_4))"
so you tried SO kernel with the patch applied and once reverted ?
but - yeah, I got you: I'm myself running a heavy patched 2.6.37 kernel with transparent hugepages, CFS autogroup, etc. enabled - and it certainly can play off its advantage most noticably during heavy system load

So, please, correct my noobiness, isn't Android using TTY shells? If it's not than I understand why this patch can't be applied, but if it is, rebuilding a kernel with just 200 lines more is no big deal and we all could benefit from it. It's not very common for Android to be under heavy load but hey, it's going to be default in 2.6.38, so why not?

There is a better patch :

But I don't know if android uses shells.

Yes, that's exactly the script I was talking about a few posts ago. On my system running 2.6.35, I did not rebuild the kernel with the "patch of wonders" but applied this script. But as you may have read, it acts in userspace which is slightly different in Android (as far as I know it's not using the same environment variables and I don't know about any ~/.bashrc equivalents, but again correct me if I'm wrong), that's why a kernel-oriented patch would be more suitable.

* well, actually newer revisions of that patch don't make use of ttys but of the task session
so basically it seems to create separate groups for each task (or program for simplicity's sake)
(source)
I'm also not sure if current Android kernel revisions use CFS at all ("Android versus Linux?")
laststufo has the autogroup patch included in his SO Kernel but I don't know how to measure its effect ... (whether it makes any difference)
* other options to improve interactivity would be to use Lennart Poettering's bash-approach (the script), like MaXo64 already posted: link
since Android uses Bourne Shell (sh) instead of BASH the script might need to be rewritten
* if it's stable enough on the SGS - yet another option would be to use Con Kolivas BFS

well, you could rewrite that script that it is run as a init-script (afaik in /system/init.d/ )
besides that:
there are stripped down (smaller) versions of bash 4.1* that are known to work on CM6 and the HTC Hero
so it should be a possibility to use that script on stock roms, too
if you can install busybox & root it, there also should be the possibility to install bash

It seems you're very well informed, so thanks for the infos you're posting!
I'm not a coder, though, so I hope a kernel developer could pick this up and go for BFS. You said laststufo already implemented this patch in his kernel, so that's really good! We should just find a way of testing its effectiveness.

[RAM Script] Tweaking Juwe11's RAM script for O2X, good for all ROM support init.d

======
Preface
======
The script is actually Base on Juwe11's RAM script
which you can found here... http://forum.xda-developers.com/showthread.php?t=1111145
==========
Main Content
==========
The adj value of his script is a bit too tight for Our O2X...
so the Launcher is killed quite often if many apps opened in the background.
Here's the adj value changes I made, originally, Juwe11's values are..
"0,1,2,4,6,15" and I change it to, "0,1,2,7,8,9"
the forth value is for HIDDEN_APP_MIN_ADJ, which including the Launcher (I'm using LauncherPro) belongs to this category when you open some foreground application.
the default android value for this is also 7, and I find the OOM value for Launcher is 6 usually... so Juwe11's "4" will lead to our Launcher being Killed, keep it at 7, never tried to have mine killed yet.
The last 2 vaule just make sure the last category EMPTY_APP_ADJ is kill earlier than the previous..
About the minfree vaule...
I change it to "1536,3072,4096,7680,8960,10240" which actually the same values of "Moderate preset" of autokiller
which is enough to ensure most RAM being use before killing for faster task switching...
=====
Credit
=====
!! Credit goes to Juwe11 for his mighty RAM script~ !!
Backup your RAMscript and remove it to somewhere before install this...
install via CWM, it will put the script into your /etc/inti.d/ that's it, boot and try

i just installed it,
i will let u know what are the results,
u are correct, the original script kills the launcher and apps specially XDA

will try this configuration on auto killer memory seems good m8 to set it to moderate

I'm not sure if other Launcher would have a different OOM value~
I have Autokiller memory optimizer which I paid before...so I can view OOM value easily..
But with this Script... I guess really no task killer needed for our 2X already.

so, just edit the minfree value according to the values inside AutoKiller if you find some other setting suits you more
but about the adj value... I guess that part is already good enough
now I find my phone already got around 60-90 free RAM at any time...
Multiple games running at the background while web browsing...
and the Browser usually got a higher OOM, which tends to kill earlier than Games..
it is reasonable.. as the WEB you can load again with the same URL..
while the game got killed, you lost the state... android is doing it's work nicely I guess.

And I found it do not contain adj value in it, so I come back to Juwe11's

thanks for that script
just a quick question
would this script also work on a sgs2, running oxygen aosp stock rom?

it was suppose to work on any ROM which support init.d

it should work on all ROM supporting init.d
in case you don't like it, go to /etc/init.d to remove the script and reboot.
it wont modify your file system..
it just override some system value on boot.
if you removes the script.. your phone would back to the state before you install this.
so, just try see if u like, if not, delete it, reboot, that's it.

Works really nicely on CM7 nightly.

Bit of a Dumb question but my phone still has the Stock rom and doesn't have the init.d Folder
if I created /system/etc/init.d and copied the script into that would this work?

You need a Custom Kernel supporting init.d to be more accurate.
and NeoBlaze is a good one to try with.
if you really need to keep your stock ROM..
First of all you still need to root your phone
Install ROM manager from market
flash the Clockworkmod via ROM manager
install NeoBlaze Kernel, then you're ready.
if warranty is your concern, take a look to the Nvflash thread..
O2X is ALMOST unbrickable, almost.

I'm pretty sure that won't work. You need ROM-support as well. (A Ramdisk script which starts the init.d. thing to be even more accurate.) Feel free to prove me wrong.

Ramdisk is a part of the kernel, so if you bung a kernel that supports init.d on (any) rom it'll run what's in there assuming it's eXecutable.
You can do it on the stock rom even, as long as you have a init.d kernel (and create the entries in ../etc/init.d/).
Although I can't "prove" this to you at the moment...

[krn.modules] intellidemand governor for Arc / Arc S stock Kernel (ICS)

Upon request from fellow member ascariz on the smartassV2 governor, I've compiled intellidemand module for Arc 4.0.3 stock kernel.
Since the firmware I use is the Arc S one (ICS 4.0.3) - I believe this module will also work for Arc S.
To fully configure / install the module, please check this page for a similar module I did for X10 back in the days - page.
Some things are different, but if you want to hand customize all possible parameters after phone starts up, the path to check is
Code:

OMG. you really do it?! tq mate!

After a day of testing, I'm switching back to smartassV2.
With smartassV2:
a) the time in state shows me about 16-17% at 1Ghz, and the others at 122MHz. Intermediate frequences are rarely used.
b) battery was about 40% at the end of the day with my usage (4 email accounts doing sync at 15 minutes - I'm not using push, but k9 connects) - also half of the day in an area where 3G signal is weak and phone swiches back and forth.
With intellidemand:
a) the time in state is 6% for 1GHz which might look better in comparison with smartassV2.
BUT:
b) the phone is sluggish and you can feel it needs a bit of time (1 second ?) to pick up speed, UI animations are choppy.
c) it does make use of the intermediate frequencies - but battery was about 20% when I got home, identical usage as previous day with smartassV2.
In both cases, screen was always kept at 25%.
Now my conclusion is that:
a) intermediate (but high) frequencies have similar battery usage as maximum frequency.
b) spending more time in an intermediate frequency makes things slower to finish and thus, based on point a) drains battery more.
Also, the code of intellidemand is more complex (.ko size is +20Kb more) as opposed to smartassV2 - and thus I guess it also takes more time (energy) to compute the correct frequency. In itself, a complex algorithm to compute the next state takes its toll.
smartassV2 does perform better with my usage pattern - and I'm curious why this governor is claimed to be advanced I mean algorithmically it surely is, but phone is more sluggish + more battery drain (not significant, but about 20% in my basic, 1 day test).
I will focus my attention on other *ass governors

The .ko was already made by viulian, here ya go.

this is intellidemand and smartassv2 modules that you can load in 2 way.
1) for those who use stock kernel that not support init.d, use script manager to load MODULELOADER script at start up. after flash, browse at system/etc/init.d folder and you will find the script.
2) for those who use kernel with init.d supported (e.g. Cobrato kernel), do nothing. just flash it and you ready to go.

Doesn't work man. :/ The new governors aren't showing up in No Frills CPU..using Cobrato's kernel.

First you must use the stock kernel from Sony's official 4.0.3 release for Arc S (even if having the Arc).
Any other kernel will not work ... (or very slim chances to work).
Second, please check using Module Loader app (but only activate the boot time loading of the module after you are sure the things work).

I have the ARC S lol, and Cobrato's kernel is Stock 4.0.3 kernel with init.d support.

Hmm...I thought you didnt have to use module loader for the flashable zips ? :/ Because the module loader shows 'Starting modules...' in the middle of any game (Like Temple Run) and it begins to lag horribly, this pisses my friends off. I want to show them how great a phone Arc/S is. :/

Ok, if it has the same version number then it will load the modules ok (as well as having the same binary kernel image).
I think the OS kills Module Loader to regain some memory, then starts it back when memory level gets better (kills it when game / heavy app starts, then as memory becomes available, it starts it back). But Module Loader has a bug and when started also loads the modules
Another solution is to use Script Manager ( http://www.androidsoftware.us/Applications/Script-Manager.html ) to run a script at boot (a small script that just do the insmod).
Hope it helps...

Thank you for your quick response. [: I know about script manager, can you please provide me with the script to use with it for the modules and a how to ? If not too much trouble that is.
Nvm, got it, thanks.

err...it should work man..i used JJ hybrid rom, and the modules shows up in the rom control..maybe you should try app other than no frills..

[FW 402][UB][6502/6503]YadliKernel, almost stock, slight undervolt, notification light mod

[FW 402][UB][6502/6503]YadliKernel, almost stock, slight undervolt, notification light mod
This kernel is based on Sony .402 source.
The goal is to create an almost stock kernel with recovery, battery saving modules, and eye-candies.
Attention: Users with locked boot loader should NOT flash this, even you have recovery!
The image will be written to the correct partition, but the BL will refuse to load it!
Credits goes to @DoomLord for his wonderful guide, toolchain and various tools for kernel building.
Features:
-75mv undervolt. No sysfs interface. Taking effect from powering on.
Notification light mod. Discussion thread [v2]
A new patch to correctly cap all cores. Compatible with all frequency setting apps. [v3]
TODOs:
Nothing TODO. Any suggestions?

Hey mate, very nice to have another developer for Z2.
It is just my opinion, but isn't -75mv will create unstable system?

I'm testing this all the time. Seems no problem so far.
I do experience random reboots one or two times a day with -100mv for my phone.
If you find it unstable, please post it here and I'll modify the parameters.
(Well in that case I think I'd better plug the undervolt interface back in )

Thank you so much. I shall test it right away and report if I come across any issues.

Can we use this with the newest firmware?

If you are talking about .438 (is it 438 or 437? I'm not sure ), then perhaps no.
Please wait until the source code for that firmware to be released by Sony.

I have a locked bootloader, but rooted (stock. 402) and using XZDualRecovery. Can I simply flash this kernel?

In that thread, some user experience crashes beyond -12mv.

for me initially -72 mV was working but not stable... for now -60 mV is mostly stable, with a rare random reboot here or there

I was nearly stable at -36 mV with a rare random reboot here or there. Now, it's seems I'm 100% stable at -24 mV and I saw elsewhere that another user was stable at -48 mV. No luck for me... Anyway, all that confirms that each device behaves differently.

Just for your consideration

I'm guessing this won't work on a locked bootloader (when has it ever?)

Thanks! I'll consider changing the initial values, or bring in the interface in the next version.
Meanwhile, a lot of people are testing this in a Chinese forum (I guess they're going for the LED mod not the unstable undervolt:cyclops. If any of them report crashes I'll update at once.
Also, in the next version I'll write a patch similar to "snake charmer" but works without FauxClock.
Thus you can cap the freqs with things like SetCPU.
I personally purchased both but FauxClock refuses to work without Google stuff.
And now I'm on a Chinese FW... Well

Hold on, I'll make a recovery zip later.
The problem is that currently I don't know how.
I'm a noob in android development

Well custom kernels aren't supposed to be able to work on locked bootloaders (changes to protected partition).
How did you change the notification light mod, maybe that doesn't require an unlocked bootloader.

The interpolation code is written in the kernel. Linear, n=16, nothing heavy.
I've already had people to test this kernel on locked BL. It did not go through BL/fastboot. Instead I adapted @DooMLoRD's installer that flushes the image directly to the corresponding mmcblk.
EDIT:
*facepalm* It did go into the partition... But locked BL refuses to load it! :/

Are we able to change individual settings in your kernel using FauxClock like DoomKernel or are all the settings hard-coded?
Not too keen on running my phone with -75mv as anthing over -24 would make my phone reboot like crazy

Currently no. But I'll include that feature in the next build.
Thanks for the suggestion.

It would be really nice if you put changelog for different of each version changing.
Thanks.

It's already there pal.

Sorry, I missed it

-75mV is to much undervolting!
it works fine in 99.5% of the time. But under extrem high load, like CPU Prime Benchmark apps like Qualcomm Trepn Profiler start to crash.
Thats a sign for unstable undervolting.

.314 FW is out, do you think to update your kernel to this new version?
