I have been using since 1.5 and no problem at all.

Daily using has left a good impact for me. I used 1400MHz max and 100Mhz 925mV with smartassv2 governor for a day w/o any lockup, reboot etc. I think I can say Its a solid stable release :)

But I miss one thing. 200MHz voltage is 925mV by default even so 100MHZ voltage is 950MHz by default. I uv'ed to 925mV. Whats the point if I use 100MHz with higher voltage?

I'm having some issue with connectbot and port forwarding.

I cannot seem to connect through the loopback interface - I've tried 127.0.0.1 and also localhost but it doesn't seem to connect at all. Would this be something related to the kernel?

The port forwards are definetely working fine since I can connect when using a PC with putty.

Thanks.

IPV6 privacy?

Should be easy to realize because it is already in the kernel and only has to be activated...

The only kernel that currently activates it, is, as far as I know, speedmod (one of the reasons I currently use speedmod)
[Galaxy S II Original Android Development] gokhanmoral:
the default voltage of 200 mhz should be 950mV. that is why 100MHz has 950mV as default, not to go below the lowest stock value. please check the default value of 200MHz again.
[Galaxy S II Original Android Development] hayspat:
I've checked again and default voltage is 925mV for 200MHz. Currently using 1.7.

Sorry i am not an advanced user , does it mean than we could use your kernel without set cpu or other apk also ?

In fact i use setcpu with param saw on tuto but don't really know what i do :p but i still have 78% after 10 hours (low utilisation)
[Galaxy S II Original Android Development] Остап:
If they are, great ))) i've been thinking that they are stock )))

I have a question. We have been learnig a lot here to save battery in deep sleep, at the time of waiting. And i can proudly to say that we are an advansed users in it now, i hope :D . How do u think what is the best way to save a lot of battery life when using ? When using a lot of screen and traffic i expand. Probably undervolting at high freqvencies - i dont know. I think i've been missin here some knowlege.

Please advice :)

Yep ! Even without setspu there is a most saving battery kernel ;) BUT ! We are always greedy, no ? :D We need more and more battery life here ))) :p

[Galaxy S II Original Android Development] gokhanmoral:
it is a bug :) the voltage levels of 200 and 100MHz should be the same.

I fixed it.

there is no harm for 100MHz being 25mV higher, but you are right it is nonesense.

[Galaxy S II Original Android Development] gokhanmoral:
I don't know about ninpho but speedmod increases only MISC charging current only by 100mA and that is already below 650mA.

I increased AC charging current to 750mA, the stock value is 650 which is pretty low compared to HTC phones. they can suck 850mA from a cheap charger (yeah, HTC sucks more :P ). some of them lower the charging speed only at levels > 90 or 95%

Btw. i am using GingerMod v0.4b with your kernel v1.7. Works great. Will try v1.7.2 now.

I saw that you are using touch-x-power. Pfffff, tried it yesterday, mann it's slow ;);)

I am using the GingerMod for a week now. Once you try it you don't wan't to switch back. It's so incredible fast and smooth: http://xdaforums.com/showthread.php?t=1220283

It's stock kernel is nimph 2.1.3. But with your kernel it fly's and saves much more battery.

I even changed the framework-res.apk for better battery life: http://xdaforums.com/showthread.php?t=1235212

I will not remove beta7 from the blog because there may be people who do not use usb tethering and like touchpad lights and can live with lower scores. maybe they will discover other bugs which will make beta8 even better.

Does the kernel still need SetCPU for better performance? I installed 2.2B7 on my gf's phone and was wondering if having it on default would help with the battery drains?

Or do I need to use SetCPU and setup profiles etc.?
[Galaxy S II Original Android Development] droidphile:
There is nothing to worry about. .android_secure refers to backups of apps in external sd. The folder would be empty.

sd-ext is significant only if you have multiple partitions on your external (plastic) sd card.

Your backup is worthy enough.

---------- Post added at 03:53 PM ---------- Previous post was at 03:49 PM ----------

For this kernel a better alternative would be Voltage Control app since it has interfaces for gpu oc/uv, charge current, etc.

Still, it is better to use init.d scripts for oc, uv, profiles, etc.

Checkout OP to find sample scripts. Detailed reference for init.d scripts can be found in OP of Q&A thread.

Despite 2.2b7 being full of bugs, I found it to be much more efficient battery-wise compared to 2.2b5.1 and 2.2b6...... a whole day of normal use and i lost 10% compared to the 25%-ish i lost on b5.1/b6

Reverted to b6 cuz of the bugs but still hope to have that kind of battery life

not sure what the changes is that make it so, maybe it's unintentional (or a bug?)
[Galaxy S II Original Android Development] gokhanmoral:
it is because second core doesn't work as expected.

if you use tegraks 2nd core app and disable the second core + set on boot, you will get similar battery life I guess.
[Galaxy S II Original Android Development] kidau:
Thanks for the quick reply! ;)

I guess that was the case, but i had better battery life when i was on 2.1.1

The tegrak 2nd core 2.2b5 and 2.2b6 was draining more even in hotplug mode T_T

Speedmod kernel is for proper newbs imo, who don't get the advantage of underclocking or undervolting. Basically just a flash and go kernel.

Hey Gokhan,stop being a teaser and release beta8 already! :p

Just joking pal.Take your time to make it better. :)

Anyway,I'm reasking whether it's possible to turn off cpu0 and keep cpu1 alive to test scaling and stability for that core because I have some suspucions that it might not be scaling that well or might not be overclocking at all.So,is it possible?

Also,it would be a good idea if the buttons' backlights could be turned on when in clockworkmod.Because as it is now,hitting back and menu buttons involves some guesswork. ;)

Well,contrary to popular belief,benchmarking programs aren't good for giving masturbation-worth scores,neither are they useless.They are a good indicator of performance levels and show you if something is wrong for a very specific setup.It's plain stupid(Although I do it too :p ) to compare scores between different devices,or the same device but with completely different rom kernel combos.Good benchmarking apps(Not that Quadrant piece of ****) can be very useful for comparing,like in this case,beta releases of the same kernel.

And to have an idea of what I was talking about in the rest of my post,try running Smartbench when overclocked at 1600MHz and after having forced dual-core mode.It's always the same mistake...
