yep was running the latest and NOT greatest version. As many have mentioned lag is noticable on Launcher scroller and app drawers. Reverted to b14 and it completely gone. I don't think it would be me only if quite a few other people are noticing the same issues.
[Galaxy S II Original Android Development] alcurtis93:
I think 2.1.1 is spot on with go launcher. Ondemandx is buggy so i use bog standard ondemand with check rom and its silky smooth and battery is awesome
[Galaxy S II Original Android Development] aeroman:
With Go LAuncher is Siyah v2.1 Final better and smoother with Lulzactive Scaler. ;)

The Version v2.1.1 laggs too much. :(

[Galaxy S II Original Android Development] Pfeffernuss:
With the kernel discussed in this thread (almost all previous versions) I also had lag-issues I must admit... Haven't tried 2.1.1 yet though.
[Galaxy S II Original Android Development] Radikaal:
With my experience 2.1 Final was much worse in launcher lagg, even wrote a post about it here comparing it between speedmod which was much smoother for me.

However 2.1.1 its much better for me then 2.1final was, but i still notice tiny bits of lags from time to time with both latest golauncher beta and launcher pro plus no matter what settings i use for speed/elastic/scroll effect.

I am one of the ones that don't give that much about batterylife since 90% is how you use your phone and what apps you use anyway! And as for batterylife 2.1.1 seems to have no problem at alls, atleast in sleep, 8hours and i stayed on 100%, cpuspy showed 98% deepsleep, and battery usage android os was down to 2%.
[Galaxy S II Original Android Development] djunited:
I have been running this kernel with cm7 for about a week now. It is unstable for me even at stock voltages. Asphalt 6 stutters, modern combat 2 causes freezes and reboots at 1200 and 1600mhz (the ones I've tested). Cf bench freezes on performance at 1600 no matter what voltage I try. Anyone has an idea what might be causing this? I'm on siyah 2.1.1 thanks
[Galaxy S II Original Android Development] mbutandola:
I can confirm this. Thought it was a problem with the launcher but as it doesn't happen with other Kernels I started thinking that the Kernel might be the issue. Hellcat's is too buggy, causing bootloops. Speedmod is good but no BLN, same for CF-root
[Galaxy S II Original Android Development] :
Since 2.1.1 my audio is stuttering, whenever I'm using my headphones, can anybody confirm that?
[Galaxy S II Original Android Development] FallenOut:
are u on 100mhz lulzactive?

does this happen only when the screen is off?

for me

this happens to me only on lulzactive at 100mhz screen off

once i change it back to ondemandx

no more problem

im usin poweramp by the way

The title is:

[Q&A] SIYAH KERNEL - NON DEV ISSUES AND QUESTIONS ABOUT KERNEL (Work in Progress)

This

thread is becoming more and more cluttered with all sorts of questions and statements that’s more suited to the tread mentioned.

It was a good reason behind the initiative from helpers of gokhanmoral and with acceptance and advice from him, to make the Q&A tread.

If we continue to clutter this thread I think both gokhanmoral, and his fellow devs. will have a hard time picking up issues that has any good input value for their continuing work on his kernel. And if he and fellow devs. starts skipping reading posts here, because of the cluttering, this thread will be worthless in a short while, and the Q&A thread too, because the lack of activity, as almost every question about everything (and nothing) is posted here.

Then we all, who benefits from his work, have lost at the end.

Just my 10¢, as I have no other power over this other than to express my meaning.
[Galaxy S II Original Android Development] Dennys_Santos:
Friend, what application you are using to graphically configure?

I tried to make some scripts manually and have not had much success in the outcome.

I'm sure the reason for my failure is due to lack of technical knowledge.

Thanks...
[Galaxy S II Original Android Development] :
100mhz - check

lulzactive - check

screen off - check

poweramp - check

Any way to fix this?
[Galaxy S II Original Android Development] netcitizen:
same issue happened to me too. not sure about the lulzactive setting as such.

I just installed the kernel thats all.

switched back to CF root kernel since I was not able to figure it out.
[Galaxy S II Original Android Development] benlc:
I've honestly never noticed any difference in performances with any kernel ( and I would say with custom roms either ) since this device is pretty... f*****g powerful.

What I can notice tho is the battery drain, and Siyah 2.1 is definitely the most battery efficient kernel I've tried until now. I leave it stock, no OC/UV or anything, and I'm pretty sure that I can say my battery last twice longer ( from ninmphetamine, dk and speedmod ) with my usage of the phone.

I've been flashing a lot my android devices, but I think the checkrom 2.0 and siyah 2.1 combo will last me until first proper ICS roms.

Nop, my post is not dev related, it is just a big thank you.
[Galaxy S II Original Android Development] FallenOut:
for me

i change back to ondemandx

u can try to change to other governer

or raise from 100mhz to 200mhz

try this first

cause i found ondemandx more smoother

bt i tested lulzactive since gokhan likes it lolz

[Galaxy S II Original Android Development] camro:
i would be happy, if i would get back the logging options as it is on beta - seems to be, that the 2.1.1 have also a problem to use the logcat on latest kernel :(
[Galaxy S II Original Android Development] Zanr Zij:
Same with me. 2.1.1 not lag immediately after flash kernel. Only after a long deep sleep time, event with TW 4.5 :). 2.1 final: same between before and ater deep sleep :).
[Galaxy S II Original Android Development] djunited:
update: after testing different roms with different kernels, it turns out the chip itself cannot handle performance governor at 1600mhz when running cf bench. however, games like asphalt 6 stutter using on demand on different roms with siyah 2.1.1 no matter what frequency. this is fixed only when selecting performance governor before playing the game. the game does not stutter using stock rom and stock kernel or any other rom with stock kernel.
[Galaxy S II Original Android Development] mbutandola:
Guys!

Could anybody tell me how I could downgrade CWM recovery to 4.0.1.5 without changing kernels? Update.zip is not working. Recovery 5.0.2.3 is causing some issues.

Cheers.
[Galaxy S II Original Android Development] Auridran:
The only governors I've seen that work properly in 3D cases are Conservative and Performance. OndemandX also seems to work, but I've never seen it go above 800MHz myself.
[Galaxy S II Original Android Development] frankcilo:
What is the script for customizable frequency step?

Can I modify all step or only first (100mhz) and last (1600mhz)?:confused:
[Galaxy S II Original Android Development] dragon546:
Are you using DK kernel or 2.1.1? if it is DK kernel check if the kitchen has an older version. 2.1.1 uses 5.0.2.7. Search for downgrading CWM SGS 2 via google

---------- Post added at 08:26 PM ---------- Previous post was at 08:24 PM ----------

There is a reference guide on the Q & A Page. It will help you understand about init.d scripts but try not to use the scripts values but start with stock values.
[Galaxy S II Original Android Development] frankcilo:
Unfortunately I have already read the guide, but I have not found what I need

I also created this script:

echo "Set Frequency Table" | tee -a $LOG_FILE;

echo "1600 1400 1200 1000 800 600 300 100" > /sys/devices/system/cpu/cpu0/cpufreq/freq_table

but it does not work!

Why?:confused:

EDIT: solved!!
[Galaxy S II Original Android Development] mbutandola:
Using 2.1.1. Made a mistake for the CWM. Been alternating between different kernels and searching google for hours but nothing came up. You can update easily from 4.0.0.4 to 4.0.1.5 easily but couldn't find a way to downgrade from 5.0.2.7 or 5.0.2.3 (that's actually Hellcat's) anywhere.
[Galaxy S II Original Android Development] :
Go to Siyah's (gok's) blog page, there's a CWM flashable version of CWM 4.0.0.X beside one of the 2.1RC kernels.

Edit: scroll down to 2.1rc1 (CWM 4.0.0.2): http://www.gokhanmoral.com/

Wow. Most of the posts here in the last couple days really belong in the siyah Q&A thread.

I just read through several pages of mostly drivel.
[Galaxy S II Original Android Development] m00moo:
Ignorant. Read what people are saying. We are experiencing launcher lag on 2.1.1 and not on b14-18. So this is SIYAH related you muppet, you are the one cluttering and no one else.
[Galaxy S II Original Android Development] olifee:
May I ask what problems CWM 5 had? Maybe they can be analyzed and solved so this becomes a dev-related discussion ;-).

Did your downgrade work fine?

---------- Post added at 11:04 PM ---------- Previous post was at 11:00 PM ----------

Please read his post correctly and stop calling others names.

This here is (supposed to be) the thread dealing with DEVELOPMENT RELATED stuff concerning SIYAH.

He linked you to the NON-DEVELOPMENT related thread, also for SIYAH-kernel.

Launcher-lag is not really development-related, but something you notice in userspace. If you pin it down to something in a discussion in the NON-DEVELOPMENT Q&A-thread, you can raise a point for further development.

So instead of flooding this thread, please pin down your problem in a discussion on non-dev-thread, and maybe make a bug-report / regression-report in this thread with all the information you collected.
[Galaxy S II Original Android Development] chadouming:
He is not the one cluttering this thread. What he said is not stupid. What's the point of repeating the same trouble over and over dozen's of times ? Once it has been said, gokhanmoral knows it. The Q&A thread has been created for people to talk about these problem and try to fix them together. This thread should become like CM7 dev. Thread and post in it only if you have logcat of what you say. Just my 2 cents.
[Galaxy S II Original Android Development] monkeydrufy:
is this kernel compatible with tegrak overclock app?

thanks
[Galaxy S II Original Android Development] :
See Siyah Q&A thread.

I believe the answer is "no".
[Galaxy S II Original Android Development] shr33kant:
Found a possible work around for launcher lag: I installed Go Launcher as a system app instead of a user app, lag gone :-D. (Please be aware that I am only posting this in the development thread because this is the one that everyone seems to be going to, I've already posted this on the Q&A thread...)
[Galaxy S II Original Android Development] mbutandola:
Thank you for your help. Basically, flashing would work randomly. Sometimes need to repeat it multiple times for it to stick. Not talking about kitchen app. I mean flashing directly from CWM recovery. And if it's something more elaborate like a theme for instance I get bootloops. Only when I flash a kernel that uses a stable CWM version such as speedmod or CF-root would the phone reboots.

I don't mind posting on the Q & A thread as long as I can get help. I think it could be good if we could chose what recovery to use with the kernel. :)
[Galaxy S II Original Android Development] Jamie1029:
I am a complete noob and sorry for asking this. But how do I change governors to smartassv2? Directing me to the correct page would've helpful if you don't want to answer it. I couldn't find it in the FAQs
[Galaxy S II Original Android Development] olifee:
Thanks for your answer ;-).

I never experienced such problems with CWM 5. If you are still on it (and did not yet flash back to CWM 4) would you mind attaching the contents of

/cache/recovery/last_log

after the next unsucessful flash? Maybe we can find something in there ;-).
[Galaxy S II Original Android Development] Radikaal:
How do you install it as a system app? :)

As for launcher lagg, im not experiencing any better on the b-14 which people recommended, its the same for me. I still think 2.1.1 is pretty good in this matter actually, top3 of all kernels i tried. But like ive posted before i experience tiny bits of lag from time to time when scrolling in homescreens which i hate having. Other then that, 2.1.1 is a great kernel and im now on 5h screentime and i have 20% battery left. Althought had one freeze (without extra UV in IMO chat app) but can live with that.
[Galaxy S II Original Android Development] tolis626:
In Titanium Backup find GoLauncherEx,long press it and there is an option to make it a system app.

Well,I just tried it and it does seem to make things a tad smoother,but it's so negligible it must be placebo.Anyway,let's not forget I'm running at 1600MHz. :cool:

Q&A
[Galaxy S II Original Android Development] olifee:
@gokhanmoral:

There is a problem with the init-script delay (I guess) for some ROMs.

Scoman in Q&A-thread has problems with the internal SDcard not being mounted if he does not clear dalvik & cache before booting, more information provided in the posts leading up to this one:

http://xdaforums.com/showpost.php?p=19087043&postcount=221

This only happens for newer releases of Siyah (where you adjusted init-script delay I think) and works fine with 2.1b14 for him. He is on XXKI3 firmware, ROM is AxLor_HDBlog.V.2.

Mounting manually from commandline works for him.

Maybe a fix will be in your special app (if init-script delay can be adjusted there ;-) ).

Is it the correct way to 'debug' a problem with users in Q&A-thread discussing it and trying stuff and then post a "compressed bug-report" with collected information here? Or are you really reading through both threads completely, so this is just double load on you?
[Galaxy S II Original Android Development] chadouming:
I do believe this is a good way to report prob. This was long enough to have all info known and short enough to not be bloated with useless stuff. ^^
[Galaxy S II Original Android Development] mbutandola:
Don't know if I'll have the nuts to go down there again. You always fear, when you see that splash screen over and over that finally you've managed to brick your phone lol

But if I do, I'll let you know. Especially now that I know there's a log that would tell me what went wrong :)

hi everyone...:)

does anyone have the same problem i have??

i mean after i flashed siyah 2.1.1v when my phone become idle i can't wake it up again so i need 2 restart my phone every time!!!!!

i reflashed back 2.0 and everything is awesome 4 now at least...:)

should i stay at 2.0 or is there a solution 4 my prob with 2.1.1??

btw i'm using sensation 1.7 rom...
[Galaxy S II Original Android Development] h20pt:
Are you using UV? If so, try to raise your voltages a bit.
[Galaxy S II Original Android Development] Alson McLaren:
yes i do!!!

i decreased the voltage using setcpu...

so should i raise it??

UPCOMING v.2.2beta1 changelog:

° init.rc changes to support ICS (not yet finalized)

° xz compression support. better compression with faster decompression (boot). not as fast as gzip in decompression but size matters more for me

° initramfs fixes to get rmmod and modprobe working (thanks to smitna)

° blue color in CWM recovery 5.0.2.7, again with back button support

° reverted some files and the speed is better now. I don't know the reason yet but it should be as responsive as v2.1beta14

° -msoft-float replaced with -mhard-float in some Makefiles. may increase speed but even if it doesn't it will not it worse

° re-enabled ARM_ERRATA_753970

!

Whoop whoop! Bring it on Gokhan:D

[Galaxy S II Original Android Development] kwerdenker:
Wake up issuses are likely to undervolting and/or underclocking? If you did any of that, please check if the problem persists after reverting to stock values. Changes in the frequency table are currently not properly anounced to the system, so anything that relies on that (eg CPUSpy) can not see these changes. As far as I remember, ghokan knows about this and was looking into a fix for a future version of this kernel.

Also you should supply more infos when submitting a bug report. Since this kernel is highly configurable and since most of the times it's these configurations that result in the problems, you should always add the configuration you used when the error came up. This should at least include any of the following, if you have made changes to it: frequency table, frequeny settings (over/underclocking) for CPU and GPU, voltage settings for CPU and GPU, governor, bus frequency settings. Also before submitting any errors, please first revert any changes you made and see if the error persists. This is especially true in case of wake-up issues (a.k.a sleep of death (SOD)) or freezes while using the phone. If the error still shows with stock settings, see if you can provided a logcat as nikzDHD said.

Maybe ghokan should put a "what is considered a bug and how-to properly submit it" in the first post... so everyone can ignore it and carry on as always...

[Galaxy S II Original Android Development] hausmanis:
I have a question to Gokhanmoral, this kernel used to be about batterylife or am i wrong ? all i see nowadays is speed/smothness discussions, what road are you heading with Siyah kernel ?

Am i the only one who thinks the sgs2 with dualcore cpu at 1200 is Smooth enough in stock, its batterylife that has real use IMO

But i can understand that you wanna please the benchmark freaks to but there is no way of pleasing both sides as the battery of the latest Siyah is worse than previous versions.

Maybe make 2 different kernels to sooth both sides ?
[Galaxy S II Original Android Development] :
Well leave it at default settings and you'll have excellent battery life, the same as speedmod. I am just finishing my test that proves so.

Not that much of a science.

[Galaxy S II Original Android Development] Molitro:
Actually I have slightly better battery life wth Siyah than speedmod.

I'm doing the same test night after night. Basically leave the phone as I use it during the day, with the same syncs and wifi on.

Two nights ago, speedmod: was in 92% after 14 hours.

Tonight, siyah: 92% after 16 and a half hours.

It's the main reason I always come back to Siyah. I don't notice all those performance differences that everybody say (Siyah performes just as well as speedmod for me), and have better idle battery life (I'm not a heavy user generally, so idle drain makes a noticeable diference to me. The drain on use depends too much on which apps are you using to notice any real difference between kernels)

In the tool you are working on, please add the possibility to set SLEEP parameter in s_volt_scheduler.

As you have already pointed out, the mediascanner for some and for unknown reasons, results in max_freq not to stick at boot.
