You misunderstood me.If and when Gohkan releases the BFS kernel I'll be all over it,not only for benchmarks. ;)

Well,I kinda liked BFS on my Hero and my Desire HD,but it didn't always turn out that well,especially after some days of use.On my Desire HD it introduced some weird lagginess and decreased battery life under certain circumstances.Might be user fault,as I tend to **** with my phone a lot.On the Hero?It couldn't make it much laggier,even at its worst days :p ,but performance with BFS and OC @768MHz was finally acceptable after having played with the then newly released HD2.

Fact is that only trial and error will show what's best.But the kernels should be identical in other aspects for us to witness any differences between only CFS and BFS.
[Galaxy S II Original Android Development] gokhanmoral:
I will release a sneak preview of 1.8 today...

It is alpha.. I even removed some Samsung optimizations and fixes to make it more unstable and fun :)

it's 90% pure 2.6.35.14, with some additions for android and platform compatibility...

I'm sorry I still could not get BFS working... so for this version we have "# CONFIG_SCHED_BFS is not set" in our config...

I am still working on it. it's my #1 priority because I also wonder the results... It used to be working great with smartass...
[Galaxy S II Original Android Development] :
exactly my point :), trials and errors.. on my nexus S there was no kernel that could even come close third to morifique BFS kernels, stabillity, performance and battery wise.

yeah :D.. can't wait :) thanks!
[Galaxy S II Original Android Development] gokhanmoral:
try it :) v1.8a1 is up...
[Galaxy S II Original Android Development] :
booted, lagfree, sio, 100-1400 :D
[Galaxy S II Original Android Development] iomemedesimosottoscritto:
Hi and first of all thank you! you are doing a great work but i have a question: i use to set the daemon for handling the cpu but even if i flash it and change frequencies with daemon controller it doesn't work from kernel 1.7.x onwards. i tried different roms so that's not the problem. could please help me? i think the daemon is a better way of handling cpu as it is faster and it kills lags. thank's in advance
[Galaxy S II Original Android Development] :
Working grate! Thanks: )
[Galaxy S II Original Android Development] gualandd:
How about introduce in Your new kernel the USB Host API's removed from Samsung on KIx kernels?

Will be a great extra!
[Galaxy S II Original Android Development] olifee:
+1, but not sure, but doesn't that depend on the used ROM?

@gokhanmoral: is "dmesg" working for you with 1.8?
[Galaxy S II Original Android Development] :
damn, lagfree is faaaaast.. lowered to 100-1000 ;)
[Galaxy S II Original Android Development] gokhanmoral:
no, it doesn't.

it doesn't depend on ring_buffer. I don't want to enable extra logging features to be able to compare the performance of new kernels with the previous ones. I will enable it in release if it doesn't have any negative impact on performance.
[Galaxy S II Original Android Development] olifee:
Thanks a lot for your answer ;-).

Guess I will live with logless droidwall up to then, just don't want to switch to another kernel :p.
[Galaxy S II Original Android Development] gualandd:
No sir, I think is kernel related; in fact 3rd part apk's that uses usb api's works perfectly on KG kernels, don't know on KH and surelly not on KI's.

I think so that is kernel related...
[Galaxy S II Original Android Development] :
damn, may I get some bugs with your kernel, pretty please? :D
[Galaxy S II Original Android Development] chadouming:
+1 Damn, so fast, so smooth. When the 1.7Ghz version? :P Just kidding. If this is a sneak peak, i wonder what the BFS or patched CFS will look like ^^. Thx for your work :D
[Galaxy S II Original Android Development] Sp33d_:
Is there a CWM.zip that removes the UV script in the init.d folder when the phone freezes on boot? :p
[Galaxy S II Original Android Development] _cummoo:
sorry folks, where can i get the oc 1696mhz version, i can't find it anymore ! pls provide a dl link.
[Galaxy S II Original Android Development] :
try adb push the same file to phone just empty from recovery (never tested it on SGS2, but it worked on nexus S)
[Galaxy S II Original Android Development] eybee1970:
ok, v1.8a1 is really smooth and fu... fast! :)...nearly unbelievable... Though I at least lost 10% in each benchmarking I did (Antutu + smartbench) compared to 1.7.8
[Galaxy S II Original Android Development] hawkerpaul:
is 1.8 going to be on a .zip or only on a .tar?

or am i being overly anxious???

:)
[Galaxy S II Original Android Development] Sp33d_:
How can I do this from CWM?
[Galaxy S II Original Android Development] ebliss:
hmm. had a freeze on 1.8a1 when I turn on wifi.
[Galaxy S II Original Android Development] :
if you have android sdk installed on our computer, boot into recovery and connect phone to computer. go to sdk folder and test from CMD: adb devices if your phone is recognized then you can ride on this horse :)

I have really never tested it on SGS2 so I really am not sure.

or just flash another kernel which doesn't support UV like chainfires or hardcores, reboot, delete script with root explorer and reinstall the kernel of your choice
[Galaxy S II Original Android Development] eybee1970:
same here :)
[Galaxy S II Original Android Development] gn00my:
Running under lagfree right now. No problems yet. Smoooooth.

Screen off profile set 100-200

Edit, also wifi freeze here :(
[Galaxy S II Original Android Development] :
download cwm app from this forums or darky rom tool from market and flash .tar :)

---------- Post added at 05:12 PM ---------- Previous post was at 05:12 PM ----------

you don't have to set screen off profile it is already in lagfree :)

---------- Post added at 05:14 PM ---------- Previous post was at 05:12 PM ----------

I just turned wi-fi on and off like 10 times and no freeze, will try some more :) .. also always do another reboot after flashing kernel, sometimes freezes are coming if not rebooted again, in my experience.
[Galaxy S II Original Android Development] eybee1970:
[/COLOR]I just turned wi-fi on and off like 10 times and no freeze, will try some more :)[/QUOTE]

it doesnt happen with e.g. ondemand...lagfree will give freeze when turning on/off WIFI
[Galaxy S II Original Android Development] rodries:
Me too, but when I try to disable wifi, so I can't disable wifi, always freeze (using default governor: ondemand 200 - 1200 no uv)
[Galaxy S II Original Android Development] :

I am using lagfree also (100-1000, lagfree, sio).

---------- Post added at 05:19 PM ---------- Previous post was at 05:18 PM ----------

do another reboot (not the one right after freeze, but another one) and test again.

also read what it says in first post :D " it is not laggy but may be buggy." :D
[Galaxy S II Original Android Development] kwerdenker:
I klnow you already got your answer, just wanted to pipe in that you can loose that second line altogether. The voltages are shared between cores and so there is no "UV_mV_table" under cpu2. This changes nothing and the script will work with the line in it, it's just not... "neat" ;)
[Galaxy S II Original Android Development] kotty:
Wifi freeze here too. .need to reboot. .
[Galaxy S II Original Android Development] rodries:
I've done 3 times ( ondemand no uv )

I know may be buggy so that's the reson I'm reporting so gokhanmoral can fix it fastly as always :)

---------- Post added at 05:29 PM ---------- Previous post was at 05:27 PM ----------

I've notice something weird, the sampling rate in ondemand governor is very low 30000, usually is about 100000 or 120000
[Galaxy S II Original Android Development] :
overclocking? (just trying to help gokhan also :) )
[Galaxy S II Original Android Development] rodries:
default kernel values

No OC or UV

ondemand governor 200 - 1200

I've tryed ondemandx & lagfree I get the freeze when I disable wifi

maybe the bug is when the phone try to switch to mobile data connection
[Galaxy S II Original Android Development] :
weird, I don't know.. switched it on and off in the last few minutes like 50+ times and no freezes, huh.. maybe clearing cache and dalvik cache or reflashing the kernel?

anyway I am sure gokhan will look inot it..
[Galaxy S II Original Android Development] rodries:
Maybe is modem related I'm using KI3

Or maybe is because now I can't get 3G only gprs because of my actual location

Or rom related, I'm using X touch power and I've seen some optimizations in net

which modem have you installed?
[Galaxy S II Original Android Development] :
KI3 also on Villain ROM, LeoMarROM and Stock (three backups :p, currently on stock). just tried to enable only gprs mode and got freeze, so yes it may be realted to switching from wi-fi to gprs (it works on 3G for me).
[Galaxy S II Original Android Development] rodries:
Great finding, now gokhan can focus on gprs to find the bug, and he can reproduce it
[Galaxy S II Original Android Development] gualandd:
I'm a total noob in this kernel, so I need an answer... For setting cpu voltage I need apps like SetCpu, right? In case I need to remove the apk, the default setting of cpu voltages are restored to samsung values?

[Galaxy S II Original Android Development] cbeckstein:
same here on stock KI3 with smartassv2 100-1400 and VR scheduler
[Galaxy S II Original Android Development] Orka82:
Going from Wlan to GPRS did not work on my phone. I had to restart to get my phone to connect to GPRS. Wlan -> 3G seems to be working.
[Galaxy S II Original Android Development] gokhanmoral:
great... so the new kernel has many bugs... fabulous :)

I'm still working on BFS so don't expect any updates before I get it booting...
[Galaxy S II Original Android Development] rodries:
Well not many, I've found only 1 :)

Wlan to GPRS => freeze

And the weird value in sampling rate in ondemand governor (not sure if it's a bug or a optimization)
[Galaxy S II Original Android Development] woodykr:
And' possible to install this kernel in an Italian telephone?
[Galaxy S II Original Android Development] eybee1970:
no, Italian phones are blocked by the dev...:rolleyes:
[Galaxy S II Original Android Development] woodykr:
Ok. which kernel do you recommend me for 2.3.5?
[Galaxy S II Original Android Development] :
Only one so far wifi to gprs (not 3g) :D

And boot that mofo :D
[Galaxy S II Original Android Development] chadouming:
waiting for that BFS version :D
[Galaxy S II Original Android Development] AndreiLux:
He's just joking :p It will work fine on your phone.
[Galaxy S II Original Android Development] woodykr:
:mad::mad::mad: ahahahahah :)
[Galaxy S II Original Android Development] gokhanmoral:
I could not reproduce those bugs in the version that I had installed on my phone to test.

so I renamed it to a2 and uploaded. I don't know what I have changed or maybe something has magically fixed all the bugs.. anyway.. a2 is up.

it is still alpha.. and still BFS is not working...
[Galaxy S II Original Android Development] eybee1970:
Thx for making me a kernel flash addict bro...:)
[Galaxy S II Original Android Development] woodykr:
then which recommend kernel me with the rom CriskeloRomV22-S-BAR7? Is this ROM all right?
[Galaxy S II Original Android Development] AndreiLux:
Just flashed a2 too and Wifi to GPRS (well, Edge in my case) also works just fine.

It will work fine.
[Galaxy S II Original Android Development] :
The problem is gone in a2 :D .. so is lagfree :p
[Galaxy S II Original Android Development] gokhanmoral:
oops.. I forgot to enable it...

old config... sorry. it will be available in a3 :)
[Galaxy S II Original Android Development] eybee1970:
But working great with smartassv2...as fast as a1 wirth lagfree
[Galaxy S II Original Android Development] cbeckstein:
wow... this fix really came quick... problem gone in version 1.8a2

BUT:

"This kernel does not support IPV6 address privacy"

1.7.8 did... Did you disable it by intention in 1.8a2?
[Galaxy S II Original Android Development] magickiller9:
is the 1.78 better than 1.6 retouch???
[Galaxy S II Original Android Development] chadouming:
Depend of your phone, personnaly i dont any difference. Try them both and you will see.
[Galaxy S II Original Android Development] gokhanmoral:
no, I just forgot to enable it back.

I will enable it in a3.
[Galaxy S II Original Android Development] hawkerpaul:
Any ideas as to when 1.8 will be available as a .zip to install via cwm?
[Galaxy S II Original Android Development] reggaemanu:
Just install it via the cwm manager app, it works fine with tar
[Galaxy S II Original Android Development] skiflyer:
gokhanmoral you actually deserve a facebook fan page. never saw a dev with such a motivation and such great improvements in every release. just awesome!
[Galaxy S II Original Android Development] SweSarah:
Is it possible to make Siyah-v1.8a2.tar in to a file that works to flash from CWM ? Im not home atm and have no data cabel here and ofc i wanna try the newest kernel :D
[Galaxy S II Original Android Development] hawkerpaul:
Both my CWM manager and CWM recovery only allows .zip files
[Galaxy S II Original Android Development] cbeckstein:
then use DarkyROM2 app from Market... that will do the job...
[Galaxy S II Original Android Development] reggaemanu:
You have to choose "flash kernel" in cwm manager for .tar, don't use "flash update"
[Galaxy S II Original Android Development] zikarus:
A tar file can be flashed via cwm manager app... Flash kernel that is...
[Galaxy S II Original Android Development] tolis626:
Hey Gohkan,I've read some good things about some governors like SavagedZen and I think they'd make a nice addition to your kernel,stable or not.Especially SavagedZen is getting some really good critics. :)

Second thing.I don't think tinkering with internal voltages is actually a good thing.I remember back when I was using stock kernel with Tegrak,someone had said that it controls the voltage of the memory controller,which explained why some users that used to lower internal voltage too much even faced data loss/corruption.So I'd leave it as it is.I never noticed any decreased battery consumption with it anyway. ;)
[Galaxy S II Original Android Development] chadouming:
Am I missing something or no 1.7.9 release ?

I think that he release .tar file for beta and alpha release for two reason. 1- It will lower the number of flash by noob people. 2- Making a CWM file for every single beta is really useless.

Also, you can flash tar file with DarkyRom II tool. Just choose the option to flash a file and select the .tar and it will flash.
[Galaxy S II Original Android Development] SweSarah:
aha thnx for the fast answers, flashing now :)

*new cpu governor lagfree. based on conservative. screen off 100-200, screen on min 500. it is not laggy but may be buggy.

Does this mean i dont have to set a profile for screen off ? Just to main to smartassv2 and its good to go ?
[Galaxy S II Original Android Development] hawkerpaul:
Ok got it now!

cheers fellas!

Wifi does not turn off

Hello!

I have a problem, which might be kernel related

The current version is Siyah 1.7.8b5 but I have that bug for every kernel that I tried, stock and custom likewise. The phone does not turn off wifi even if the policy is to turn it off when it is not used, therefore it drains battery.

Does someone know something about this issue?

The only prog that might relate is k9mail.

Thanks:

Denke.
[Galaxy S II Original Android Development] chadouming:
This is in fact a known Gingerbread bug. Put your policiy to never and you will less battery gain.
[Galaxy S II Original Android Development] Denwa:
Try flashing SU3 from andoridsu.com. It should fix any issues.

I'm Flashing 1.8.a2 from CWM manager (flash kernel) and on reboot I still have the older 1.8. /EDIT TYPO!

Any idea why the flash is not taking place?
[Galaxy S II Original Android Development] zikarus:
Hmh let's think: you assume a kernel related issue since you encountered your problem on all kernels you've tried? It therefore is unlikely that the issue is kernel related - might be a GINGERBREAD problem instead...
[Galaxy S II Original Android Development] chadouming:
hmm, first there is no 1.7.9 version its 1.8 :P

try again. flash with DarkyRom II tool this time
[Galaxy S II Original Android Development] hawkerpaul:
the latest version in 1.8a2.

Flashed fine for me via CWM Manager
[Galaxy S II Original Android Development] AndreiLux:
It was me who mentioned that; I was getting corruption while doing music playback and the music player would freeze. I raised internal and everything was fine after that. While maybe it's dumb to have undervolted internal voltage as default, it's up to the user to decide what he wants. And for that matter I want to lower it, so who cares. Gokhan said its' something simple to implement so why not. I want to test it. Nobody really did some proper testing on batterylife, and really it's something you wouldn't normally notice unless you know for what it matters.
[Galaxy S II Original Android Development] Denwa:
T'was a typo. Damn kernel changes so fast my fingers aren't up to speed on what my brain sees. :D

I'll try darky2.

---------- Post added at 02:09 PM ---------- Previous post was at 01:56 PM ----------

OK, tried CWM rom manager and Darky2 ROm manager and both say they are flashing but on reboot I still have the old kernel.

Any ideas?
[Galaxy S II Original Android Development] chadouming:
redownload latest version and try again ?
[Galaxy S II Original Android Development] tolis626:
Aha. ;)

Well,**** if I saw improvements in my battery life.I am overclocked at 1.6Ghz for the CPU and 400Mhz for the GPU and I use full screen brightness.Even the AOS bug drains little battery compared to my usage. :p

I just wanted to suggest that he leaves default values as they are.If he does provide an interface for handling internal voltage,I'll be more than happy to test. ;)
[Galaxy S II Original Android Development] Denwa:
Redownloaded it 3 times. Twice with tapatalk and once with opera and none will install. I give up for now.
[Galaxy S II Original Android Development] chadouming:
honnestly ahve no clue of your problem, sry
[Galaxy S II Original Android Development] D108:
I have d/led v1.8a2 and the latest darkyrom tool and it worked 1st time...

Try latest v.1.8a2 and latest darkrom tool and flash from SDCARD and choose the .tar file... it worx :)

Cheers

D
[Galaxy S II Original Android Development] Denwa:
Did that but no go. Upon reboot it whips though the recovery dialog so fast you can't read any of it.
[Galaxy S II Original Android Development] zikarus:
Seems to be a corrupt dl. Delete the downloaded kernel file, THEN dl it again and flash once more...
[Galaxy S II Original Android Development] Denwa:
I'll try again, but I downloaded the third one on my home computer with opera and transferred it to my phone with dropbox so it should be a clean download.. I will try again though.

---------- Post added at 04:08 PM ---------- Previous post was at 03:57 PM ----------

4th download..still doesnlt work.

I don't think it's an issue with the .tar. I think it's something on my phone preventing the flashing of .tars with CWM or Darky2. They both say flashing... then reboot and no changes.

I'm on leomar 2.7.1 rom. With a fixed version of SU 3. No clue wtf is causing this.
[Galaxy S II Original Android Development] blk15:
This. The tenacity of the developer is admirable and deserving of praise.

Keep up to good work! :)
[Galaxy S II Original Android Development] chadouming:
If your at your home, can you try to flash the .tar with odin plz, we will be fixed.
[Galaxy S II Original Android Development] cbeckstein:
this could be related to the known strange problem I mentioned in my post #2212 to the kernel author and which is discussed also in the speedmod XDA thread or the GOA trip ROM thread

if it is the same problem, then the only known solution to this is to flash

1) a pre KIx ROM (e.g. KH3) and then

2) the Frankenstein version (that without the new boot loader) of KI3

after that you should again be able to successfully flash any kernel you want

by now nobody has an explanation why some SGS2 develop this nasty habit of not accepting flashing certain kernels nor why the above two step procedure usually solves the problem
[Galaxy S II Original Android Development] hausmanis:
Anyone compared the batterylife of the regular Siyah kernel and the reTOUCHED one ?
[Galaxy S II Original Android Development] chadouming:
Nope, i'm flashing addict :D so can't really speak about battery life.

[Galaxy S II Original Android Development] chadouming:
because you didnt read a few post before posting your question

---------- Post added at 08:24 PM ---------- Previous post was at 08:23 PM ----------

Strange that this kernel is not working with AT&T phone since it's AT&T source that is used.
[Galaxy S II Original Android Development] Denwa:
I'll flash with odin later. Don't trust this netbook....
[Galaxy S II Original Android Development] javichulo:
sorry for this noob question. but with this kernal and the notices about updates using xxx governor based on blah blah.. etc. does this mean by flashing it i have those set already and no need for setCPU?

so frequencies and voltages are already set by the kernel and i don't need to do anything?

BUT, i can use setCPU? and if I do, it will override these settings?

what if i use setCPU then emove the set on boot options.. does it then revert to kernel defaults?
[Galaxy S II Original Android Development] ebliss:
1.8a2 is a total disaster for me. After flashing the kernel, the device freeze again at "Media scanner running... (usb storage)". Tried it 10 times, 10 times freeze. Wipe cache and dalvik twice on separate occasions. Still doesn't get past that stage. No uc/uc/oc yet. No scripts in init.d.
[Galaxy S II Original Android Development] chadouming:
Kernel is not undervolted or overclocked by default. So basically, without using SetCPU or voltage control ( Free version disponible ), you will have a 100 - 1200 Mhz kernel, no UV and tweaked Ondemand governor. Which should run smooth but might drain battery a bit. Using a programm to change this might enhance the battery consomation but is not needed.
[Galaxy S II Original Android Development] chadouming:
SetCPU with on boot setting ? happened to me some times. Flash this if it's the case.
[Galaxy S II Original Android Development] H a R 0:
This isn't compatible with 2.3.3? :(
[Galaxy S II Original Android Development] chadouming:
why not evolve to 2.3.5 ?
[Galaxy S II Original Android Development] ebliss:
No. I am very cautious when I come to this. I make sure setcpu is not set to anything. And I make sure init.d is empty.
[Galaxy S II Original Android Development] chadouming:
hmm, might try the file i posetd anyway , it's the file dropped from SetCPU in case something go wrong.
[Galaxy S II Original Android Development] H a R 0:
hmmm. so i have to flash my phone to the XXKI3 then (2.3.5) then flash this kernel right? thanks! :)
[Galaxy S II Original Android Development] chadouming:
Yup ^^
[Galaxy S II Original Android Development] Pellel2:
1.8a does not work after the media scan ends. all the apps do not show up anywhere. could be this init thing working after media scan is done. I have SetCPU to start at boot. maybe it could be that as well I did not try disabling it as I could not get into the phone. Had to reflash ninphetamine kernel to get phone to work
[Galaxy S II Original Android Development] chadouming:
Try to flash the package i linked 1 page before.
[Galaxy S II Original Android Development] blk15:
Works on XXKH3 (2.3.4) as well
