Just an update, I managed to get it to deep sleep. Just had to stop playing with the phone and it was ok.

As a general guideline I was able to UV my phone with the following settings... no freezing or anything so far.

1000 -75

800 -50

400 -50

200 -25

100 -25

No OC right now... i might later.

[Galaxy S I9000 Android Development] stratosk:
It is better to undervolt higher frequencies with lower uv values and the opposite.

CPU frequency on stock music player when screen off to 400 MHz

how do i check that?
[Galaxy S I9000 Android Development] stratosk:
Use CPU spy application. Reset statistics, open the music player, listen to music for a couple of minutes with the screen off. Then check the statistics in CPU spy.

Personnaly i think this:

Hi dude,

Can you make kernel with Linux kernel 3.0.4 ?
[Galaxy S I9000 Android Development] mbarreto:
With Stratosk kernel?

You think I can flash it together with Stratosk kernel?
[Galaxy S I9000 Android Development] darckengel:
Yes you can.

But before you should backup the following files:

- in sytem/bin:

* app_process

* system_server

- in sytem/lib

* libsqlite.so

* libsqlite_jni.so

To revert back if you don't like it.

I also change a little the init.d files to use noop scheduler instead of cfq (as it's by default with Semaphore).
[Galaxy S I9000 Android Development] mbarreto:
Thank you! Will flash it right now :)
[Galaxy S I9000 Android Development] tartakobsky:
Super fast big big thanks!!!

Switched from galaxianEE, no more browser hang and FC and reboots

yes, in 100 mhz is processor most of the time. So high value for this, btw, which utility use to overclocked? thx
[Galaxy S I9000 Android Development] ssj4Gogeta1:
Thank you, now I just need a confirmation on whether it works with JV9 2.3.3 ROM. Never flashed anything before.

Also, someone posted in the CF-root thread in this post a specific way to reproduce the bug - reboot, turn wifi on, turn wifi off, try to turn bluetooth on. Can you please confirm whether everything works fine for you when you do that. :)

One more confirmation - I have DDJV9 while samfirmware only have DXJV9 for download. I want to confirm whether both have the same kernel, so that I can flash back the stock kernel if Semaphore doesn't work correctly. I have no way to backup my kernel as I don't have root. Thanks again.

EDIT: Got download link for DDJV9 in this thread.

Can you make another v1.6.0 without voodoo color ?
[Galaxy S I9000 Android Development] HM.Carbide:
With v1.6.0 is both possible, speedmod color and voodoo color.

speedmod scripts are to initialize speedmod colors.

With voodoo control app you can choose your own colors.

To get original speedmod colors, you have to additionally set gamma hack to 2.3.3 default (0, 0, 0).
[Galaxy S I9000 Android Development] stratosk:
You may use S05_enable_oc script for overcloking. Please read the first post for details.
[Galaxy S I9000 Android Development] rom08:
Just a noob question again but i have put the neutral color script in init.d folder then reboot but i can still sees the color hacks in voodoo app and change them . Is it normal? With the script shouldn't voodoo color hack disappear in voodoo control?

Edit : the time i write my post the question is already answered. Thanks
[Galaxy S I9000 Android Development] stratosk:
I don't think so. Maybe it's better these tweaks to stay out of the kernel.

I want the kernel as pure as possible. You may flush this stuff any time you want.

Including this in the kernel, everybody will be forced to use this. And I don't think this is kernel related but android os related.

Please note that I don't mean that this does not improves performance. I just don't want to create the illusion that the performance improvement it is due to kernel that includes these OS tweaks.

Also note that Enhancerv6 removes the journaling from ext4.
[Galaxy S I9000 Android Development] stratosk:
I' m afraid is not possible.:)
[Galaxy S I9000 Android Development] petulikt:
One more question, can i check or uncheck some tweak in your semaphore tweak, i mean swapiness or something other? or this check options are best?
[Galaxy S I9000 Android Development] stratosk:
Of course you can check or uncheck every option you like. I don't use all of them. :)
[Galaxy S I9000 Android Development] petulikt:

thanks
[Galaxy S I9000 Android Development] stratosk:
Thanks!

I have already answered this question few posts earlier.
[Galaxy S I9000 Android Development] stratosk:
No, if you want to OC you have to use the S05_enable_oc script.

Then you may use voltage control for undervolting.
[Galaxy S I9000 Android Development] tush1114:
Means without overclocking, voltage control cannot be used. Is it correct?
[Galaxy S I9000 Android Development] stratosk:
No, sorry for the misunderstanding.

You may use undervolting (with voltage control) with or without overclocking

But if you want to overclock you have to use the S05_enable_oc script.
[Galaxy S I9000 Android Development] petulikt:
and why you didnt inlclude this script into the kernel?
[Galaxy S I9000 Android Development] coldhandz:
Hi Petulikt, what script do you mean?
[Galaxy S I9000 Android Development] tush1114:
Thanks for clarification.

Now my understanding is-

Oc and uv are two different things and can be used independently.

[Galaxy S I9000 Android Development] stratosk:
I don't want to do it because I don't want to mix tweaks with kernel. And because I want (as much as possible) to be clear to the final user what is happening to the phone. I don't want for example to remove the journaling in user's filesystem by default. Maybe this will make the device faster but it's risky. If someone wants to do it he may run this mod separately.

I hope it is more clear now.

Greetings,

I'm sorry if this has been talked about before (if it has can someone kindly direct me to where it's mentioned?), but there are loads of pages on this thread for me to go through and there doesn't seem to be a way to search for a term(s) in just an individual thread (at least not that I can find). Anyway I've noticed a small thing with the boot animation upon each boot up of my phone after installing this kernel, nothing that bothers me that much, just curious about why it happens. The boot animation plays for just a few seconds before going to a black screen, it doesn't play the animation all the way through like it should do (at least until the phone boots up). I've noticed this more prominently after flashing a theme, for instance, since the dalvik cache gets cleared and takes a bit longer to boot up. Is it just me or has anyone else experienced this? Before anyone says I've got the wrong version for my ROM (see my sig) I did also try this with the JVQ version of the kernel to match up with my ROM, and this did the same thing.

Any help would be appreciated. Thanks :).
[Galaxy S I9000 Android Development] test03:
Hi everyone. Thanks stratosk for this great kernel.

I have a little problem (don't know if it's kernel related): Sometimes the default android Music player and Winamp cannot access my internal SD, even though ES File Explorer can. The workaround to this problem is to unmount and mount back the internal SD in the Settings menu. I don't know if there are other programs that can/can't access the sd, because I've not tried with others.

Is there something else I can do? Thanks!

PS: Galaxy S EUR i9000, with Juwe 5.3 and Semaphore 1.6.0 (updated yesterday). The problem was also on 1.5.0.

the bar has not moved and i know this is a procedure that takes seconds

any help on what to do?

I like your work! other feedback too

Hi stratosk,

I really like ur last version of the kernel 1.6.0, I use him now for 2 days and I have some feedback too:

- right now i use the same settings like and i think big programs like iGo are starting faster! thanks for that

- i observed that is still room for improve the autobrightness, meaning i think u still can add one more low dim step, optional, in the cwm menu. The same option I had in Froyo 2.2, in SpeedMod kernel. I think with this step we can save more battery and still benefit form ur stable and fast kernel ;)

What do u think?
[Galaxy S I9000 Android Development] firsthtc:
And one question: since I flashed this kernel (I had DarkCore before) I can't find any menu in recovery about the filesystem and option to change. It is normal?

I ask that because I wanna switch /system to rfs and keep the others ext4

Any help? Thanks :)
[Galaxy S I9000 Android Development] stratosk:
There is no such option in CWM. You can use chainfire's ext4 application for the conversion but it will convert all partitions to ext4.

Thanks for your feedback. I will have in mind about the auto brightness.
[Galaxy S I9000 Android Development] firsthtc:
Feedback

Soooo happy to hear that about the auto brightness :)

about CWM: there was such an option in Froyo, same speedmod kernel... I insist a little bit because I always used /system on rfs and all the rest on ext4 - maybe is only in my mind but I felt like the battery is a little bit more protected (meaning less consumption)

Anyway, I am pleasantly surprised to see that u r really take a look at the feedback. I had another experiences, not really good, here around in other threads...

Excellent :)
[Galaxy S I9000 Android Development] andip71:

Hi,

I use this kernel and i am happy with semaphore 1.6 and jetpack rom.

Kind regards

[Galaxy S I9000 Android Development] stratosk:
@darckengel

The version I promised. Please remember that this is going to affect not only music player cpu frequency when screen off. The change is in the early_suspend process in the kernel and I didn't investigate what will happened with this.

@all: this is a test version. It will not lock the frequency to 400Mhz when at early suspend e.g. when the music player is on and the screen goes off. Do not use it as a stable release

Oh come on. It was discussed several times in this forum. IT IS kernel related. Just use stock or supercurio's stock+hacks jvp kernel and you will see that auto brightness works fine.
