Just installed setcpu from Market.

I cannot scale it to 1.2ghz

Max is 1000 MHz (1ghz) and It was set to max 800MHz ....

Maybe something with speedmod kernel ? Which I use since yaok is crashing
[Galaxy S I9000 Android Development] manageri21:
What do you mean, if it works in sortware mode means that everything is fine,

but you try on another kernel the software mode and will work for you, always talking about rockplayer

because for me on software mode it play slow with the 720p 256Hz kernel k9a xxjpo

i'am not expert but in software mode i think is normal to be slow, if i'am wrong tell me i'am happy to learn always something new
[Galaxy S I9000 Android Development] tokyogtr:
it crashes in software mode for me at 1.2ghz. this is a thread for ya-ok.
[Galaxy S I9000 Android Development] tokyogtr:
speedmod is 1ghz. ya-ok is 1.2ghz. no wonder you're seeing differences. install ya-ok again and run setcpu. select auto detect frequencies. select 100 min and 1000 max. run your angry birds and gps tests. if no crash, then up the scale to 1200. run all the tests again. be sure to select conservative scaling though.

Anyone getting user errors in /system/user.log when using this kernel

I'm getting ziplign and /mounting /dev/block/stl9 on /system failed: Device or resource busy.

My setup is in my signature..
[Galaxy S I9000 Android Development] tokyogtr:
sounds like file system corruption to me.
[Galaxy S I9000 Android Development] elhpianist:
It can't be, cause using Speedmod K9A or K10 kernels, these errors don't show up in the user.log.. Also I always do a fresh install on any new rom

It still boots up fine and everything is smooth, just feels uneasy having that in my /system/user.log file
[Galaxy S I9000 Android Development] manageri21:
i now this is ya-ok thread i use this kernel but i change every time when the dev guys post some new kernel.

it crashes is i want to now because never try in software mode with this kernel only hardware mode and when i see your post i try with the other kernel and just to tell you

sorry for my english is not my language.
[Galaxy S I9000 Android Development] tokyogtr:
ok, speedmod is 1ghz ONLY. nothing should crash at 1ghz, not even YA-OK when it's set to 1GHZ. the rockplayer test in software mode is purely to stress the phone when set to 1.2GHZ to see if it crashes.
[Galaxy S I9000 Android Development] tokyogtr:
ah. just re-read your mail and thought you ment that was a boot up message. yeah, i get that in my system user logfile too.

[Galaxy S I9000 Android Development] dimio:
i just flashed my SGS right now with this new kernel build of zenkinz, no problem for now !

1ghz -> 1550 -> no change under quadrant, i do not feel that the SGS became a little bit much more smooth now

1,2ghz -> 1768 -> of course the SGS is really much more smooth and a little hot :)

OverclockWidget -> do not seems to generate FC for now

angry bird -> no crash / no overclocking (really useless with this game) for now

asphalt 5 -> need to test that under 1,2ghz as many people reported that the SGS may crash after 30 min...

note :

- i flashed a JM5 the last week

- then a JPM

- then the last kernel build of zenkinz (1.31.build.31)

- then activated the lag fix (EXT4) + all the tweak on

- this evening i hadn't removed the lag fix and others tweaks at all.

i just flashed the kernel as i supposed that logicaly i could not have any problem with a zenkinz kernel upgrade ;)

Except the fact i frightened myself with a first flash attempt which failed via ODIN :D i thought i bricked my SGS because of the shutdown...:eek: (odin maybe:confused:)

but in fact it was very interesting to see that the SGS was locked on the screen "connection fail sgs <-!-> pc" until i rebooted the SGS into the download mode.

and then everything was fine with ODIN, i was able to flash again and everything is fine now :D
[Galaxy S I9000 Android Development] betoNL:
Hello, Just back and just saw your post.

Yesterday I change my config. back to YA-OK, to test it in conjunction with Setcpu app. as you suggested.

After 3 hours of testing here are my findings:

If I configure setcpu to 1000MHz MAX (conservative scaling) no crashes (at least till now) at all.

But after setting setcpu to 1200MHz conservative, system will eventually crash, with whatever type of usage or app..

I am new to flashing android devices but my guess is something to do with the overclocking and how it is implemented.

After trying many firmwares and lately many kernels (never applying lag-fixes), I can say that with YA-OK kernel, I experienced 3 different things for the first time:

-Quadrant benchmarks over 1000 (with no lagfix)

-Crashes (yep, never experienced that before)

-Some minimal lag while running heavy apps. like Motonav and Angry Birds( cause a I have to set setcpu to max 1000MHz to avoid crashes), (no lag at all when setting cpu to max 1200MHz).

My conclusions so far:

In my case if I have to set cpu to max 1000MHz, YA-OK v.1.40 kernel will be less responsive than Speedmod K9A.

When I set cpu to max 1200MHz YA-OK will more responsive but system will eventually crash

End report
[Galaxy S I9000 Android Development] lokhor:
I'm using the speedmod but would like a kernel that does uv as my battery life is terrible.
[Galaxy S I9000 Android Development] tokyogtr:
i can only assume that 1.2ghz conflicts either with your hardware or some other software running on your phone. don't run any of those memory management apps. also, disable all the hardcore tweaks.

my never crashes, EXCEPT for rockplayer software mode. also, never run a hungry app like angry birds etc at 1.2ghz with the power cable plugged in. it WILL overheat and crash.

also, i found that without lagfix the phone definitely can bog down. i don't care what anyone says about lagfix not really making a difference, it really does. i run overkill ext4 + ext2 without data binds and my phone flies and never bogs down. yes, it will consume slightly more battery, but so does running at 1.2ghz.
[Galaxy S I9000 Android Development] tokyogtr:
define terrible and what apps are you running? UV is built into YA-OK, no need to mess with it. i run superpower and it makes the world of difference. i've even programmed it to turn off a selection of apps when i turn the screen off, as well as data etc.
[Galaxy S I9000 Android Development] betoNL:
Ok, tks. Going to do some more tests and report later....
[Galaxy S I9000 Android Development] wcg707:
I'm currently running insanity rom with ya-ok @1.2 and not having any crash yet. Angry birds tuning fine a well. Battery wise, 100%-20% on 10 hours normal use wifi, push email from google, angrybirds 1hr, surfing and others. Hsdpa enable must of the time. Quadrant is 2276.

lagfix jfs/ext2.

Will test battery idling tonite and update again tomorrow.
[Galaxy S I9000 Android Development] elhpianist:
I had 1% battery drain overnight(8hours) idling using this kernel, mind you I also used SuperPower XDA battery app with everything turn off, except 2G on
[Galaxy S I9000 Android Development] manageri21:
thanks for the explanation
[Galaxy S I9000 Android Development] lokhor:
My idle battery life is fine, for example overnight (8 hours) I had 5% drain. It's my active usage that is not very good. My longest on screen time has been 3.3 hours and that was with data disabled the whole day, the entire battery only lasted 14 hours with that usage. Usually if I don't disable 3g and I use JuiceDefender my battery will last around 11 hours with 2.5 hours of screen usage.

The only background services I have running are:

Tasker, JuiceDefender, clockrupdateservice, vlingo safereader, snsservice, omadrmconfigservice, cloud to device messaging, google messaging service and Swype.

I set my screen to 0% brightness pretty much all the time to save battery and I have bluetooth and gps disabled as well.
[Galaxy S I9000 Android Development] tokyogtr:
that's not the kernel's problem, that's the screen. and yes, it sucks the juice down like nothing else. you might try resetting your battery stats and doing a full battery refresh cycle though.
[Galaxy S I9000 Android Development] betoNL:
After testing other kernels, my conclusion is that somehow my sgs cannot handle 1.2Ghz overclocking.

But I find the feature OC/UV, a must.

So I started a thread where users could talk about their kernel experiences and opinions:

And in there I found a very good kernel :

Advanced Voodoo 5 Stable RC1 Edition v1.0

And I am using the version with 1.12 OV that means UV/OC for me and no crashes

1000 quadrant with no lagfix and some how my internal gps receiver is flying! Fast locks during a cold start with no agps.

Is there a connection between an optimized kernel and the gps receiver performance ??

I have tried this multiple times, and I cycle between 1 oem battery and 2 chinese batteries. The chinese ones have worse battery life however even the oem battery appears to have poor battery life. I know that it is not related to the kernel, however I was hoping I could find a way to reduce my power consumption to the point that my battery lasts a full day (7am-11pm)
[Galaxy S I9000 Android Development] tokyogtr:
have you turned off auto brightness, screen animations and auto rotation?
[Galaxy S I9000 Android Development] tokyogtr:
kernel and gps? shouldn't be. should all be rom and modem based. what rom are you running with voodoo? and do you have any of the tweaks enabled?

some i9000s are running inferior cpus. if yours is still under warranty i would actually flash yours back to stock, take it back and demand a new phone. tell them anything, like it crashes all the time and gets very very hot and that you're afraid it's going to catch fire... :)
[Galaxy S I9000 Android Development] ImraanK:
Guys just wondering...

Can i flash this over CF-Root ? Will i lose the features CF-Root kernal has like root ?
[Galaxy S I9000 Android Development] betoNL:
Stock Rom, no extra tweaks(just the ones already implemented by dev), no lagfix, no file system conversion yet .

Return the phone? No way! It was flying with speedmod K9A and now it.s even smoother with Trasig's advanced voodoo 1.12Ghz OC...nice colours, sound and great gps performance. You should try it. He got a 1.2Ghz version.

I would think about returning it if they would give money back, so I could try a htc desire hd...

Actually...naaahh

Ps- GREAT battery performance
[Galaxy S I9000 Android Development] lokhor:
Yes I keep brightness @ 0%

I also disable auto rotation most of the day (except when driving)

Not sure about screen animations.
[Galaxy S I9000 Android Development] tokyogtr:
screen animations and live wallpapers are a huge battery killer. turn them both off.
[Galaxy S I9000 Android Development] tokyogtr:
but you understand my point right? just like cars, even though they say they're identical some have faults, some have slightly more HP than others. it's becoming obvious that there are different flavours of the i9000 and they are NOT all the same. there seems to be a very poor batch of cpus out there, as there also appears to be a bunch that are amazing. it's a matter of getting the best config.

maybe it's time for a new thread with a matrix showing all the flavours of the i9000 and what we've found they are capable of handling. my uk i9000 with 8gb can handle 1.2ghz fine as long as i don't run setcpu actively or rockplayer software mode. i haven't tried it with 1.4ghz but who needs that anyway!
[Galaxy S I9000 Android Development] zenkinz:
the rockplayer problem seems to be partly attributed by the video itself. I transfer one 720p video (avc+ac3 in mkv container) and it plays very smoothly under hardware decoding and jerky in software decoding (normal, since it's a hd playback) but never have crash.
[Galaxy S I9000 Android Development] tokyogtr:
i recorded a 720HD video on the camera and then played it back in hardware mode and it was fine. but playing it back in software mode, it crashes. can you try doing a HD video from the camera and then playing in rockplayer.
[Galaxy S I9000 Android Development] mpierce:
Thank you for you work!

Running your kernel with Doc's BUJ8-V9 much quicker than the SpeedMod kernel!

Quadrant on your kernel is in excess of 1,550 vs about 1,000 with the SpeedMod kernel that Doc includes as standard in this rom and that is without OC (1,750 with OC).

Wondering if your kernel supports a bootanimimation.zip?

I put a file in the /system/media folder and nothing happened.
[Galaxy S I9000 Android Development] azreil24:
Tested 1.4 for a few days and went back to 1.2. Is you greatest work. With 1.4 the battery drain is higher, ram management is worse, I got random freezes and resets. I flashed the kernel as I do with every other, clean flash, no lagfix applyied, wype etc. Still love your work do, hope your newer version will be at least as good as 1.2 is :).

Cheers.
[Galaxy S I9000 Android Development] -NRG-:
Great kernel! Absolutely the smoothest for me, but 1.2ghz is to much for my device with this kernel, browser crashes at heavy websites. 1.2ghz does work with this kernel: Trasig's Kernel http://kernel.1ug.org but it doesn't have the futures or the smoothnes as with your kernel. Is it possible to check what the difference is between 1.2ghz of yours and of Trasig's kernel? or maybe make a 1.1ghz kernel?

Thanks in advance and for the work you've already done!

(BTW using v1.40, installed setcpu after crashes to clock it back to 1ghz to test, i didn't have crashes @1ghz)
[Galaxy S I9000 Android Development] elhpianist:
No this doesn't have bootanimation.
[Galaxy S I9000 Android Development] betoNL:
Flavours huh?

As long as the ARM Cortex A8 chip in my sgs can process 90 million triangles per second (the Snapdragon platform can reportedly handle 22 million triangles per second), I don't really need to overclock it to 1.2Ghz.

What I wanted was the whole feature- undervolting/overclocking in good balance in my sgs; and I got it, thanks to this great Kernel (trasig's)which I am using at the moment....

As I don't need lagfixes also, since I never experienced lag.

And what about that great gps performance, with stable and fast locks , running programs like iGo Motonav flawlessly?

In some gps threads users told me that I just have to accept the fact that my sgs got a more capable gps receiver, when I confronted them with my videos, so here cames the "flavours" theory again.

There are no "flavours" man or..... are there?? or maybe "added" flavours?

Bring on the Matrix (thread) ;)
[Galaxy S I9000 Android Development] dupel:
Its not CPU, its GPU. And since there are like 5 games that can actually sort of challenge our phone (and its a Big sort of) its completely useless to us.

CPU is just about 10% faster than snapdragon (old version) and just about the same as new version.

So oc gives Huge power boost.
[Galaxy S I9000 Android Development] Myscha:
I've just had to reflash my stock JPO + SpeedMod kernel because it was giving me a huge lot of Force Closes, and afterwards I read that it could have been due to having reinstalled apps + data via Titanium Backup.

My question is: this problem also occurs with YA-OK? I've already flashed it, and no FCs have happened yet, I would like it keep being this way...

(sorry if this is a stupid question, it's been my first day of messing up with roms and kernels, so I'm a total noob)
[Galaxy S I9000 Android Development] tokyogtr:
i've never had any problems with ya-ok. it's very stable. i also restore data using titanium backup and it's find.
[Galaxy S I9000 Android Development] elhpianist:
Not kernel related at all.

If you're re-installing apps via Titanium backup, make sure you only install user apps + data, and not system apps (if your coming from a different ROM).

[Galaxy S I9000 Android Development] wcg707:
Need to ask a 2 questions:

1. Where does the logfile is written to? It seems everytime you touch something on the screen it will be log.

2. I keep seeing a lot of this messages when I did dmesg

[PWR] set_gpio_dvs : Invalid parameters (5)

Anyone else seen this? This is repeated every 2 secs which may affect performance since it is writing this somewhere.
[Galaxy S I9000 Android Development] jsen:
Also got same when dmesg.
[Galaxy S I9000 Android Development] mikeysteele:
You should flash the Kernel using PDA.

[Galaxy S I9000 Android Development] tokyogtr:
you talking about disabling at the CWM level or the app level?

[Galaxy S I9000 Android Development] elhpianist:
I think there is a bug in "old" BLN 2.2, as Zenkinz hadn't had the time to update it or implement it in 1.40.

[Galaxy S I9000 Android Development] aurangzeb:
the ZIP file should be place on Internal SD or External SD??

confused here
[Galaxy S I9000 Android Development] tokyogtr:
i don't think you should be doing this if you don't know how to recover from it. there are plenty of threads that you should read first about the dangers of doing this. but if you must do it then you need to place the zip file on the internal SDCARD and flash it from there. do you have CWM?
[Galaxy S I9000 Android Development] aurangzeb:
yes...i`ve download it...that`s why i`m asking because the older post said place the zip in the external sd

hmmm....i cant reboot into cwm...grr
[Galaxy S I9000 Android Development] tokyogtr:
internal is fine, just in case you cannot mount the external one. you should keep a repository of cwm zips in your internal sd card so you can relfash roms/kernels in case you get a hung phone.

Nice. I hope I could do overkill without binds, but the last time I did it, I had major loss of data. Do you feel any realtime performance improvements with 2200+ quadrant than with 1500+ quadrant score?
[Galaxy S I9000 Android Development] matshako:
Quick question, probably answered before, but bear with me.

I currently have Hardcore's K10E speedmod on my SGS. I am also using EXT4-no-journal overkill lagfix. Do I need to remove lagfix before flashing to YA-OK?
[Galaxy S I9000 Android Development] elhpianist:
Yes you do, YAOK doesnt support ext4nj and still uses ULF 0.3 lagfix options.
[Galaxy S I9000 Android Development] zoubidou:
i have been reading through the thread about nj. they still don't know if this really brings any benefits. it seems logic in a way, but I have a bet that journalling is only happening when there is any activtiy. And if your phone has any activity, journalling will probably not increase battery drain or very minor, compared to the other activities.

I am using YA-OK since the first version and I always had a stable kernel and no battery drain and high speed.

ok I will update in the first post later. Going for dinner now.

Good work. Consider the newly released kernel with uv-mod by raspdeep.

Edit: Flashed, works, lagfix No-RFS overkill + OC-on: ~2240 Quadrant & ~17000 MFLOPs Linpack, OC-off: ~2000/14000

I saw if you overclocked like this and use your phone on usb with wlan enabled the delivered energy by usb is not enough to increase battery level, but rather the level is decreasing. Can anyone confirm this?

For those who like scripts I attach mine:

I use "GScript lite" to disable or enable Overclocking.
