I dont have this device but I stumbled on this thread and following my previous question Entropy I suggest you to turn off dynamic hotplug since Im pretty sure this Exynos arch dont like it very much. I disabled it on my Note kernel and not only it improved interactivity but it improved battery and stability. I can explain why if you so desire.

Theres another option you should disable, there is a config option called SKIP_CALIBRATION if Im not mistaken. Since the exynos cpus are not synced with one another they dont share the sane loop per jiffy value, which is not good. Disabling that option the board is forced to calibrate the lpj on both cores, and thats something we want.
[Galaxy S II Original Android Development] bleuxeon:
I have never tried to force both cpu's allways ON.

I will give it a try to see how battery life is affected.
[Galaxy S II Original Android Development] Entropy512:
I've seen your comments on hotplug on OMAP, such as indications that it was hotplugging in and out as often as 10 Hz. This is not an issue on Exynos, where the default behavior is to check for hotplugging in at 2 Hz and hotplugging out at 0.5 Hz. (Well that was the case for Gingerbread, I need to review it again for ICS)

Hotplug MUST be enabled on Exynos for proper power management, as unlike OMAP where deep idle states can be entered when both CPUs are hotplugged in but must agree on when to enter idle (based on what I can understand of the OMAP code, I admit I need to read it in more detail), all idle states that involve power gating are blocked when CPU1 is hotplugged in - https://github.com/Entropy512/kerne...r/arch/arm/mach-exynos/cpuidle-exynos4.c#L755

garyd9's tests on the Tab 7 Plus at http://xdaforums.com/showthread.php?t=1494653 were flawed - he measured when the device was connected to USB, and a USB connection to PC appears to cause enough interrupts to block even AFTR mode (Based on the fact that when I backported the Tab 7 Plus cpuidle code to Gingerbread, it caused video decoding problems for some people which would always go away if they were plugged into USB but not to a non-PC charging device - I never had time to verify that USB plugging did change idle dynamics, I should check later this week). (Actually, I think on ICS kernels, due to differences in target_residency, if AFTR was blocked with the Honeycomb cpuidle code, even the most basic IDLE state will be blocked on USB with ICS.)

If forcing the second CPU on helps stability, it's an idea of where to look though. I won't be able to look at this until tonight though.

I'll look into SKIP_CALIBRATION.

Edit: I can't see how stability could be improved by improving hotplug on Gingerbread Exynos sources, since it was stable to begin with. The only stability problems I ever encountered were due to the cpuidle backport - which is probably why the ICS cpuidle code has PM_SUSPEND_PREPARE notifier handlers in it, and some weird negative interaction between AT&T firmware bases and I9100 update3. Only people running UC bases seemed to have issues.
[Galaxy S II Original Android Development] franciscofranco:
Ok all that seems fine for me, but can you then explain why me and my Note kernel users report a lot better battery life with dynamic hotplug off? Do you have any idea of the hotplug costs? That power gating idea doesn't cut it for me because I've seen with my own eyes the difference between dynamic hotplug on/off difference.

Push Volume up, home and power..holed them down till it boots into recovery and volume down, home and power for download mode. Is that what you wanted to know?
[Galaxy S II Original Android Development] ByTe_cOdE:
No,mate...!!! I am asking about the key trigger set to boot into second rom.How is it configured in the kernel source?

BTW,thanks for your heads up...!
[Galaxy S II Original Android Development] It_ler:
I don't know about a key trigger for that.

But you can select the ROM you want to boot in recovery mode.

Maybe there you can enable to ask on each boot for the ROM too.
[Galaxy S II Original Android Development] ByTe_cOdE:
Okay,So,it's about recovery.

Thanks,mate...!!!
[Galaxy S II Original Android Development] budsixz:
Actually when the phone is booting it gives you three seconds to choose which rom do you want to boot

Within that time if we press home button then second rom boots or if v press power then primary boots

If the 3 sec timer expires then primary rom boots by default
[Galaxy S II Original Android Development] Many40:
To be more precise - it doesn't concern Siyah ver6 which doesn't support dual booting at all. GM didn't manage to finalize implementing this feature into the latest v6 betas.
[Galaxy S II Original Android Development] ByTe_cOdE:
Okay..!!!!Thanks mate....!!!But,I searched a lot.But,I couldn't find the recovery source....!!!

[Galaxy S II Original Android Development] Many40:
Hi,

Even GM stopped kernel development some time ago, it's still a development thread and as GM didn't want this kind of basic questions to be posted here we should respect it.

Please repost your question in Siyah kernel discussion thread.

Then me or someone else will guide you how to install Siyah kernel using PC Odin or mobile Odin.

[Galaxy S II Original Android Development] MadMax1978:
Hey you all, I am trying to use a Sitecom (based on Asix 88772 chip) network adapter, on a rooted Samsung Galaxy S2 with official 4.1.2 ROM. Used it with the latest, siyah kernel which should be compatible with my Samsung Galaxy S2. I even copied this with the adb push command, which seemed to work but the adapter won't work. I also tried insmod over adb or terminal with su but with both mii.ko and asix.ko. Both ko files should be the right ones, but I am not for sure. With the insmod command it says that the module was not in the right format! When I check in os monitor I don't see an additional network adapter. Also tried to reboot with the adapter connected during reboot.Even the led's on the usb ethernet adapter will blink. I can read or write usb flash sticks with the otg adapter. When I use the adapter on the Samsung Galaxy S4 (without root) it will show up in os monitor with it's mac address as eth0 but it remains down. But the leds go on. And I probably need root to bring it up. But the adapter itself seems to work. It fully works on an Archos G9 tablet, without modification on this tablet, but you have to enable the 3g stick option. You also get en ethernet adapter icon besides the clock.

Can anybody help me with this? Does this only work on an older android version (4.0.x)? And or with and older Siyah kernel?

Would be great if anyone could give me a hint!

[Galaxy S II Original Android Development] metalgearhathaway:
This a wonderful governor, I am using it with latest stable Boeffla Kernel on i9300. In Boeffla you can tune the settings in the governor, but the list of possible adjustments is pretty exhaustive and I was wondering if there is any information available so that I can properly understand the functionality of the items therein?

Many thanks!
[Galaxy S II Original Android Development] robertobsc:
Hi metalgear,

I am really happy that you are enjoying the governor that i, with Gokhan's assistance, created.

Unfortunately i stopped any development, but i enjoyed so much making it as well.

About your doubt: There's at least two links describing governors in details including Luzactive and its Q variation.

One is the jurassic and spectacular thread by droidphile: http://xdaforums.com/galaxy-s2/general/ref-kernel-governors-modules-o-t1369817/post19846276

Other is a thread of mine, but is in my native language (i'm Brasilian): http://brasildroid.com.br/galaxy-s-...ks-script-gs2-tweaks-bateria-performance.html

Well, google translator may be helpful.

Just to explain about the "Q": It indicates that this governor has a independent hotplug logic, as pegasusQ has. But i also don't know what Q means!! = )

[MENTION=2174044]Many40[/MENTION], how things are going? Long time i didnt see you. = )

Cya everyone!

Cheers.

[EDIT]: Sorry to mess up the dev thread. = )
[Galaxy S II Original Android Development] metalgearhathaway:
Thanks so much for that! This governor is marvelous and runs a real treat with my setup. Forget intelliactive and zzmoove, lulzactiveq is simply superb, wiping the floor with then both with a great mix of lagless performance and kind on the battery also :good:

Thanks for remembering me still my old friend :)

I'm fine - still on s2, still on Siyah kernel (6b4) and I still hope that one day [MENTION=289089]gokhanmoral[/MENTION] pops up here for short time and fix his recovery to make dual boot working. It's the only feature I'm missing from the kernel.

I know I'm naive but we say in Poland: "faith can move mountains"

I see you are on s4 -> are you supporting any kernels for s4 with your governor?

End of OT (moderators forgive me - but it's [MENTION=4486415]robertobsc[/MENTION] who is guilty for that mentioning my nickname ;))

Does this work well on XWMS3? I installed and the kernel worked, but sometimes i get an unreasonable freeze, which makes the touch screen useless (power, volume and soft keys still respond). I try philz kernel which match the latest build and there was no freeze
[Galaxy S II Original Android Development] Rated RR:
I would say it's unfortunately 'normal' for Siyah and Dorimanx kernel which are apparently based on same source, where there is something deeply unstable in them.

I tried number of times to stabilize Dorimanx kernel but each time without long term results. Recently, i tried to go with Siyah just to find out it is behaving pretty much the same. That's too sad, as they offer advanced features plus OC.
[Galaxy S II Original Android Development] Many40:
Are you on default kernel settings without any UC/UV?

- if yes, increase voltage by 50mV for the lowest GPU freq step

- if not, reset to default settings and see.
[Galaxy S II Original Android Development] pipyakas:
Ah yes, all the freeze come after i change something in stweak, specially gpu oc

Will try it for a couple if minutes and see

Edit: well i guest that it's beter then, less freeze than before. But i got a big battery issue, that after heavy usage (playing games or sth) and reboot, my battery drop from 60-80% to 20% or less. But when the power goes down to 1%, the phone turn off, and i turn it right back on with 12%. How could that happen? 2 batteries, 1 problem. I guess that it's the phone that causing the issue then, but what is it?

The Official MIUI rom has a built-in kernel that is good enough ( Siyah Kernel Dual-Boot version )

Do you know if there are roms like paranoid android rom or P.A.C. rom or something else popular rom that i can try as dual-boot?

It has to be Jelly Bean BTW

Hi,

I understand your pain due to unusual battery draining however:

1. this is a development thread and even the dev stopped his development such kind of questions should be better asked on Siyah kernel discussion thread - http://xdaforums.com/showthread.php?p=26205430

2. With background info you provided noone will be able to guess what exactly drains your battery.

I would recommend that you install betterbatterystatts app and take a proper dump (log) file. You can upload then the file on the app's thread asking to analyse it for you.

Hello

where can I download

philz cwm 6 stock-kernel signed.zip

can I install from CWM siyah ?
[Galaxy S II Original Android Development] TriboDoP:
Hi

I do not have the link at hand.

Please just search for philz cwm6 stock-kernel GT-i9100. As far as i remember you have to scroll down quite a bit to downloads.

Look for Kernel which has your build number (or close to it). As exampel: philZ-cwm6-XWLSD-OXX-4.87-signed.zip

You can install it from your recovery. And of course you can flash back with philz recovery to siyah (zip-file).

Also you could install custom roms like kitkat On your device with both kernels/recovery. For higher roms like cm 12, 13 there are some more things needed.

I am not sure if philz kernel will see 64GB card but its not much work and can be reversed easily.

Btw is it not recommended to not use cards bigger than 32gb? For this reason i never used bigger ones - but it worked for you anayway.
