I wish I knew the answer of the first part.

as I have stated before, all I did was to move to linux2.6.35.14

maybe it has some trick to mask it, not intentionally of course..

however, for the second part, there is a good reason for cf-root and stock kernel has better battery:

they have better display, sound and wifi drivers, and others...

I don't claim that there are magical tricks in this kernel to improve the battery life...

but even if you just slide the lower freq bar to 100MHz using setcpu you should get noticeably better battery life.
[Galaxy S II Original Android Development] KennyLegend:
Thanks very much for ur honest answer. Im still using v1.8 by the way. Love its features.
[Galaxy S II Original Android Development] lpsi2000:
Yes, CM7 is pretty nice. I am also trying Galnet MIUI and it is also pretty nice. It is nice to see the device with 600MB of RAM available after loading all of my apps.

Sorry for bringing the topic CWM latest 5.x.x but I now understand why some people would want it. I say please include it your beta and RC releases. I also understand the need to stay with version 4.x.x on your release version of the kernel. As you mentioned in this thread previously, if we don't try it then they won't be able to make it better. It is good to be able to use the external SD for backup and to flash other stuff.

The decision in your hands and either way I am good:D
[Galaxy S II Original Android Development] gokhanmoral:
That is exactly what I am going to do: include latest CWM recovery (testing)

and since latest rc and release are supposed to be the same people have the opportunity to choose.
[Galaxy S II Original Android Development] lpsi2000:
Man, I don't wish to be in your shoes. It is so difficult to keep people happy. But I must say you are doing a great job:D

Thanks.

[Galaxy S II Original Android Development] olifee:
Hello all,

referring back to my post here:

http://xdaforums.com/showpost.php?p=18299539&postcount=3712

I got some arbitrary USB-stuff working. Gokhanmoral also promised to set corresponding options in the next kernel (maybe 2.0 already?).

To tease everybody a bit :P, I shot a nice photo today. It shows my Samsung Galaxy SII connected to an USB-hub, to which a digitizer is connected (actually, USB-OTG did not give me enough power).

This digitizer can digitize an analog waveform with up to 5 GS/s and works in Linux. The corresponding software is Open Source, so I used Debian with chroot on my Galaxy S2, compiled it, used vncserver and androidVNC, and there you go!

The waveform generator can also be seen on the picture ;-).

So there is something you can look forward to! If you compile ftdi_sio- and usbserial-modules with gokhanmorals sources, usbserial is working, too!

Unlimited possibilities! :)
[Galaxy S II Original Android Development] gokhanmoral:
you are right. :)

let's lower the expectations: there are already some bugs that I could not fix. :P

my primary goal is not to cause new bugs in samsung roms while trying to fix bugs in AOSP based roms.

also, there are some boot-time features are missing for now.

it will be added in time, such as automatic battery calibration, efs backup etc..
[Galaxy S II Original Android Development] Остап:
Gokhan, what about laggy grafics ?
[Galaxy S II Original Android Development] jmblazquezh:
Many thanks for the explanation. The truth is I do not understand much about it, so I asked. Incidentally, once I got the option to go to the previous menu in recovery 4.0.0.2, but can not remember which keys to press. I think it's an option that is hidden and appears with a keystroke.

Regards.

using cm7 nightly 80

everything's fine

but with u'r 2.0 beta2 it's sooo much smooothier and no problems with sensivity of display (they were with "stock" cm kernel)

smartassv2 100-1000

great job, will see about bugs, if they're there
[Galaxy S II Original Android Development] xeq544:
Is there any point in flashing 2.0 if I am using samsung rom ? Or is it just 1.8 with cm7 support
[Galaxy S II Original Android Development] Vaedryn:
Great :) Flashing now under CM7
[Galaxy S II Original Android Development] gokhanmoral:
there are some fixes. if you are already happy with 1.8's performance you don't need to flash it.
[Galaxy S II Original Android Development] AndroidGX:
Just flashed 2.0b2, and 10 sec after the samsung boot logo, black screen for 3 good minutes, then the desktop appearing :eek: nice bug :D

I'am alone in this case :confused:

Boss ??? :D in spite of we are man ....................... i love you :D
[Galaxy S II Original Android Development] dtekkt:
My phone is not booting up for the first time with your kernel, maybe it is because of my uving? But I never had this before,always flashed newer releases of your kernel without removing my script. So I'm back to 1.8 atm :(

Nvmnd, I think its because the bootanimation is missing and I haven't waited long enough, will try again tomorrow if it works
[Galaxy S II Original Android Development] AndroidGX:
OK I found why, it's because you removed custom bootanimations feature, isn't it ? black screen every boots until desktop.
[Galaxy S II Original Android Development] AndreiLux:
Yea, bootanimation's missing. (Btw I'm replacing the bootanimaiton, not using the custom bootanimation "feature").
[Galaxy S II Original Android Development] gokhanmoral:
really? with cm7 or samsung rom?

this is beta anyway :)

I was on stock rom during testing. now I will flash touch-x-power..

it can be fixed, I hope :)
[Galaxy S II Original Android Development] Denwa:
It's the new "omg I bricked my f*cking phone!!!" animation. Quite nicely done. Very minimal. Possibly the best boot animation out there. 5 stars.

By the way. There is a bug with boot animation ( or like this ) Since i've tried import directory for your logo i have "charging.jpg is missing" while phone is charging in off mode ... do you know about it something ?
[Galaxy S II Original Android Development] jmblazquezh:
Hey...my recovery version is now 5.0.2.6 in blue color.....:confused::confused::confused:

Edit : reflashing the bootanimation, no solution for the problem
[Galaxy S II Original Android Development] afcp:
No boot animation on leomar also
[Galaxy S II Original Android Development] hawkerpaul:
v2 beta2 seems to delete the boot animation

also it has reverte back to CWM recovery 5.0.2.6. Is this intentional?
[Galaxy S II Original Android Development] yeahtyeaht:
can i use this kernel for miui?
[Galaxy S II Original Android Development] eybee1970:
performance is great of course...I am on MIUI

But there is a weird prob with USB-connection to my Laptop....it doesn't work as usual, I get crazy behaviour, laptop screen is running crazy and File Explorer freezes....rigth now flashed back to latest CM7-Kernel --> no prob at all...so must be related to kernel in some way?!

guys, do you always post without reading anything?

KNOWN ISSUE: boot animation is not working.

and read the first post. for beta versions I use latest recovery.
[Galaxy S II Original Android Development] AndroidGX:
Read the changelog on first page :
[Galaxy S II Original Android Development] gokhanmoral:
yes I know. there is a problem with USB connectivity in AOSP roms.

I will solve it in the next release.
[Galaxy S II Original Android Development] Vaedryn:
With cm7 boot animation works fine
[Galaxy S II Original Android Development] gokhanmoral:
I have added known problems to the second post.

there are 2 for now...

BLN and CM7

Looking great, but BLN is giving me the lib lights not supported error?

Is BLN not functioning on CM7 even with the beta2?

rooting

why you root removed? Now a kernel without root?
[Galaxy S II Original Android Development] velgador0:
Fantastic, thanks, now working!
[Galaxy S II Original Android Development] gokhanmoral:
because it was causing a lot of problems with custom roms.

if you need root just install cf-root.

it will copy su and Superuser.apk files

then you can flash this kernel and you won't lose root.

Custom roms already come with root anyway, so it is not needed.

lots of people will be happier but some will have to flash either another kernel first or flash this kernel with odin then flash su package in CWM.

and that is VERY easy...

you won't lose anything but lots of people will gain time including me. I won't have to struggle with solving some weird root issues...

Flash 2.0beta2 kernel on MIUI Rom :) my feedback:

everything seems to work well, really well, however, testers better tomorrow and give you confirmation or denial ...

only one thing at once .. the haptic feedback only after reebot work correct .. but go broke after some minute and dont work .. the only way to have back it is restart GS2...

Thanks for your work gokhanmoral :)

great stuff --- even with the test cwm in the betas B-)

two instant observations on stock KI8:

1) script manager app no longer works (just black screen upon start, must be killed)

2) charging currents can no longer be read from the kernel via script
[Galaxy S II Original Android Development] :
stupid question. once i flash this kernel on cm7 stable version can i use setcpu if i wanted to? thanks again

The answer to the second faq question is now yes!!!
[Galaxy S II Original Android Development] :
thank you so much you kind young sir..:rolleyes:

not everyone follows the thread as much and i just saw someone telling me and i just wanted to confirm....so thanks for the confirmation...cm7 finally a rom i can use everyday now

---------- Post added at 05:20 PM ---------- Previous post was at 05:17 PM ----------

Exactly... Thanks
[Galaxy S II Original Android Development] incubus_fr:
Did I quote you? No.

I only asked Gokhanmoral to update the faq.
[Galaxy S II Original Android Development] yhrn:
First, thank you so much for your efforts with this kernel!

I'm currently on 1.8 (stock KI8) and I get pretty bad battery drain. I've always been affected by the AOS bug (often 60% AOS, suspend and events/0 going through the roof) but mainly when on wifi (15-20% per hour on wifi, 2-3% on mobile data, <1% with no data, auto sync always on, very light usage).

I then flashed this kernel and was delighted to see that I now had similar drain on wifi and 3g. However, after a while I realized that I now get maybe 5% drain per hour (very light or no usage) unless I disable data completely. AOS is down to around 25% but the strange thing is that "tvout resume wo" is now the main drain according to BBS, closely followed by "suspend". Tested 1.8rc2 as well with same results.

So to summarize, compared to CF-root I experience much less drain on wifi, maybe double drain on 3g and "tvout resume wo" showing up as the main drain in BBS (never seen it anywhere close to the top of the list before).

Anybody else seeing this? Or does anybody have any idea what "tvout resume wo" is and what could make it drain my poor battery?

Cheers
[Galaxy S II Original Android Development] Molitro:
I'm really looking forward to this kernel when samsung releases the 2.3.5 sources, and to see if we can actually save some battery.

With the AOS issue solved (aparently, and I don't think it's just masked), I gained some idle battery life, but still I'm nowhere close to where I was with the SGS.

Let's hope the new drivers help with this (well, actually lets hope that samsung solves the drain issue itself so then we can have kernels like this built over an already decent battery life...)
[Galaxy S II Original Android Development] peachpuff:
I noticed vibrations are borked with 2.0b2 on miui, android os is down to 15% usage compared to 40-60% with other kernels, so far so good.
[Galaxy S II Original Android Development] gokhanmoral:
Thanks. I have updated the faq.
[Galaxy S II Original Android Development] ludalex07:
What do you guys think is the best setup for battery conservation? Any KI3 (or KH3? what's the best?) custom rom + cf-root kernel?
[Galaxy S II Original Android Development] Denwa:
It seems init.d scripts are being ignored with 2.0b2. Anyine else notice that?

--sent from a faster than light sub-atomic particle
[Galaxy S II Original Android Development] Radikaal:
This AOS bug is kinda weird, is it only some phones who get it?

I never had bad idle drain on my phone from KH3 roms>KI8, if i get more then 0.5% drain / hour with DATA on in idle with not using phone i know something is wrong, if the reception is good phone can drop only 3% in a 10hours of time, with data OFF as low as 2%.

Perhaps try a different modem, i did notice for example KF2 did drain my battery more in idle then for example KH3, KG5 and KI4 (current). And disable fast dormency, set weather widgets to manual locations if you can live with that, dsiable samsung app thing, set your syncs to manually and it should be fine.

And this is with other kernels, only tried this one a couple of versions but i still think it lacks speed & responsiveness to be the best kernel.

2/0 leaping. Lagging in passing screens :mad:
[Galaxy S II Original Android Development] gokhanmoral:
I don't notice any lag with 100-1400 smartass or ondemand . It is even smother than 1.8 for me.
[Galaxy S II Original Android Development] Molitro:
The thing is that if you have to turn everything off, owning a smartphone such as this kind of losses it's purpose.

Specially considering that in the first SGS, from the first 2.3.4 rom there are no such problems, and I had network location, emails on push, auto-sync... and had that 0.5% per hour on wifi drain, and not more than 2-3% drain overnight. As it should be.

But, judging from the experiments I've been doing today (and will keep doing tomorrow as I calibrate my battery), as soon as I have something on push, being emial, or I think even whatsapp, or have network location, the battery starts to drain like crazy (to a point where it's draining 1% every 45 minutes aprox.). And that's without the AOS bug.

I don't know what the hell is the people at samsung doing, but it's really enerving that they eventually did it right with the SGS, to then go backwards with the S2.
[Galaxy S II Original Android Development] akira888:
I haven't tried 2.0 yet. But from my personal experience, smallassv2, lagfree and ondemand in v1.8 are all not as smooth as the stock ondemand. I am using 200 - 1200. Previously I used ragemod kernel's ondemand governor, which I believe is stock.

But AOS high usage is gone in this kernel :)

[Galaxy S II Original Android Development] AndreiLux:
So, gokhan, did you look into the CM7 aos bugfix commit? If it's nothing more than the .14 patches everybody's been using, then i can come to the conclusion that it doesn't fix **** / slightly changes it. Every once in a blue moon my AOS usage goes way up to crazy levels and eats up battery nonstop, and is pretty unrelentless. The lst 2 days have been like that. I tried kernel over kernel over kernel and they all have the same drain, with the difference that the supposedly patched ones, just don't show up the percentages or statistics of the processes anymore. I reflashed to stock KI3 and it has exactly the same drain, and most importantly, a ridiculous resemblance in CPUSpy in terms of frequency states, the only difference between stock and any latest Siyah being that stock actually shows the AOS% and enormous CPU time and .14 "patched" kernels do not. The screen off & <800MHz profiles and monitoring if it still goes into the 800MHz state to see if the bug is active or not is still pretty much the most accurate tell-sign.

Funny thing is that it was fixed for me at the beginning, but now I've reverted to every single version of the kernels (even legendary alpha4), and none of them fixed it again. I even wiped the phone competely. Many people say they don't notice a battery difference even with the AOS% going down, and this might be pretty much the reason.
[Galaxy S II Original Android Development] pachinkosan:
So

with cm7 there's bootanimation on it's place

it's very smooth, no laggin

aos here is kinda 3% (at stock was 6%)

no random reboots or freezes

but usb isn't working correctly

vibration is smooth and not so strong as at stock (but i like it much more, honestly)
[Galaxy S II Original Android Development] r4stafari:
Siyah v2.0 after flashing, reboot no animation? Is it suppose to b that way??
