No, it charges at 650mA 750mA (see 1.6 changelog, I don't know if it still applies), that's the default value set at the moment. But with this kernel, you have the option to manually change the charging rate up to a maximum of 950mA. A 2A charger is a bit too much for the battery anyway.
[Galaxy S II Original Android Development] tolis626:
No no,you misunderstood me.I didn't ask if you can make a kernel with 1500Mhz maximum frequency.I asked whether I can change your normal max frequency myself without needing to recompile the kernel,like we can change voltages on the fly.

And,believe me,the 100MHz of 1400->1500MHz is more noticable than those of 1500->1600MHz. ;)
[Galaxy S II Original Android Development] crypticc:
What problem? I am on the 1.8 b4 and it rocks.

I clocked mine at 5000 with performance @1.6Ghz on both quadrant and smartbench. Got hot as hell. but after test and returning to smartass cooled off very quickly. 1.2 for daily running for me though.

thanks to op
[Galaxy S II Original Android Development] pappschlumpf:
Same here. After enabling logger everything is fine with su. All apps needing permit at boot are working. Without the logger the permit comes years after boot. Well i need logging anyway, because of an app protector.

Great kernel, the best! thx!
[Galaxy S II Original Android Development] dimkrom:
but the script in the first post says that it change it to 1000mah
[Galaxy S II Original Android Development] AndreiLux:
Not quite as impressive. The kernel right now isn't as optimized for speed as it could be. In the screenshots below you can see me on MIUI and XCeLL kernel running at 1.6GHz, and the other one stock speeds. I hope we can bring Siyah up to similar speeds in future versions.
[Galaxy S II Original Android Development] gokhanmoral:
ahh, I see. well.. it is possible :) I can make frequencies adjustable via an interface similar to voltage control.

I will put it in my todo list, but surely it will not be in my priority list...

Great work on the awesome kernel.

Cheers!

Have one restart without any reason :mad: of phone since using 1.6 ... keep watching ... :cool:

100 MHZ - do u mean down volting of 100 or up volting of 200 ?

BLN - if it possible via liblights or something else to disable mail & gmail BLNing ? I want to use it on calls & sms-mms only ...
[Galaxy S II Original Android Development] jaykhan:
Stable at the lowest possible CPU voltage.

Just want to report about the battery consumption, remaining 92% now and running for 10+ hours mostly idle (overnight)

I am still on v1.5. Here are few observation that I need you expert opinion;

1- Scaling is ondemand, CPU remains at 100MHz when phone is left idle but when I change scaling to smartassV2 CPU keeps jumping to 500 & 800 MHz even in idle.

2- Other thing I noticed is when phone is restarted the battery stats is reset automatically which should not because it will loose history and battery calibration.

Thanks again.

Hehe thanks dude for the SC-02C version^^
[Galaxy S II Original Android Development] :
Working fine on SicOpaT's KI4 Rom ;)..

Now be brave and make a BFS version as no one has done it yet (dear morfique, buy a galaxy s 2 please :D)..
[Galaxy S II Original Android Development] adit17:
strange

i flashed this kernel combined with DK V3, and i use smartassv2 gov but why battery drain so fast, after flashing i lost 6% (from 28%-->22%) and then drop to 3% in only couple minutes (now my battery remains 3%...)

i really don't know why i got this

help me please with the setting, i am really really noob here... :confused:

thank you so much
[Galaxy S II Original Android Development] :
recalibrate your battery first (as it clearly states in first post) and see if there is still drain, use app alike better battery stats to see what is causing wakelocks.

[Galaxy S II Original Android Development] unun281292:
Sir where is the gpu and voltage control interface?
[Galaxy S II Original Android Development] :
asnother version of galaxy s 2, yes (i guess you mean cwm app not cwm).

read the first post again.. if you mean GUI, there is no GUI for gpu yet (for cpu use setcpu or similar).
[Galaxy S II Original Android Development] Hamst0r:
How much faster is the improved batterry loading speed? I miss my iphones charge speed (up to 100 % in 1 hour and 20 minutes). SGS2 needs more than 2 hours :/
[Galaxy S II Original Android Development] gokhanmoral:
I increased the charging current from 650mV to 750mV and it affects the charging speed linearly.

I will make it adjustable in the next version for those whose time is more precious than sgs2's battery...

Hello people

How do we change the io schedular as this kernel supports such a wide range

I googled it but got lost at echoing the comnands to the superblocks

Advice appreicated....

[Galaxy S II Original Android Development] _cummoo:
Yes, this is excactly what i said. The performance of 1.8rc1 is not as good as with 1.8a..xx - 1.8b..xx. And for the first time on 1.8rc1 we have some heat issues to face. (all governors)
[Galaxy S II Original Android Development] HellRazorGod:
For some really odd reason , Ive noticed that SetCPU tends to consume more battery than save with undervolting . Maybe some wakelocks.

I've always noticed better battery life without SetCPU than with .

Strange things happen. And I hate ironies.
[Galaxy S II Original Android Development] AndroidGX:
+1

I tried several profiles but less bugs, smoothness and better battery drain when SetCPU does not handle anything, I let the app only handling UV at boot.
[Galaxy S II Original Android Development] jonny68:
Exactly how did you manage to stop the AOS bug gokhanmoral when so many have tried and failed before you.

I assume every dev will be implementing this fix this into their Kernel too.
[Galaxy S II Original Android Development] ram3n:
So, if SetCPU causes more battery drain, what alternative can we choose ?
[Galaxy S II Original Android Development] diddsen:
and what is with 100mhz range?... that brings nothing?

i think that this is the most important thing
[Galaxy S II Original Android Development] dtekkt:
Use voltage control, it doesn't run in the background but makes a script
[Galaxy S II Original Android Development] gualandd:
Are the usb host api's implementare in this kernel release?

[Galaxy S II Original Android Development] AndreiLux:
We still don't know what's causing it and what fixed it, just that it's fixed right now. I also heard that the Androidmeda kernel doesn't have the bug.

If you mean this, then that's not part of the kernel but the ROM. Normal USB OTG works.
[Galaxy S II Original Android Development] ObihoernchenDE:
RC1 is builded with GCC version 4.4.1 2009q3 which is pretty old and doesn't have all Cortex-A9 optimizations iirc.

All betas are builded with a newer GCC (4.5... 2011q3 and so on)

I think this causes the issue.
[Galaxy S II Original Android Development] frankcilo:
+ 1

Setcpu cause more battery drain, Voltage Control no, because makes script, then it is more fast, how dual core script, that I use with all kernel
[Galaxy S II Original Android Development] AndroidGX:
Of course it is, but I suspect the 100 Mhz to do some random reboots, as I just did there is 1 hour by letting the phone idle at 100 Mhz with ondemand gov. That's why I said "less bugs" in this sort of :)
[Galaxy S II Original Android Development] zantekk:
can someone post the flashable ocdaemon (which creates the folder called "virtual" or something like this^^) ?

can't find it, the thread is too big...

i think the uc/uv script from the first post only scales one cpu, doesn't it?
[Galaxy S II Original Android Development] tolis626:
Aaha,that's what I'm talking about. ;)

Well,no rush,I just wanted to know if it's possible.If you can,do it.If you do it,I'll be grateful.If you don't do it,I'll be grateful for everything else,so not to worry. :p

Seriously though,there are more important things,so I ain't demanding anything.Do your thing. :)
[Galaxy S II Original Android Development] ram3n:
Guys, with Voltage control, which I/O scheduler should I set ? noop, deadline, cfq, vr or sio ??
[Galaxy S II Original Android Development] megazz:
Guys, is it possible to use this kernel with the lite'ning rom?

[Galaxy S II Original Android Development] dtekkt:
I have deadline atm and I'm pretty happy with it
[Galaxy S II Original Android Development] bandit79:
So it's better to use the b4 instead of rc1?
[Galaxy S II Original Android Development] gokhanmoral:
I was suspecting that some optimizations and new codesourcery toolchain were the causes of problems.

I used linaro-2011.09-4.5 toolchain in rc2

I have only removed cfs low-latency patch and made some little modifications which would not cause any lockup or random reboot.

if we have problems I will revert back to old toolchain.
[Galaxy S II Original Android Development] gokhanmoral:
I have uploaded rc2.

test it.

if you wait for the final version and find out a bug it will take longer to fix.

test it, find bugs and report them while my cpu is still hot so that I can fix them quickly..

try tegrak's touchmove app. it is cool.

I updated CWM recovery and su in rc2.

cfs patches are removed.

I used latest linaro 4.5 toolchain. if you have random reboots I will blame it or optimization parameters.

if rc1 is working stable this version should be running at least as stable.
[Galaxy S II Original Android Development] Vger1:
Yes... But do your self a favour and try this kernel with Batista , that combo is a winner.

With lite'ning, speedmod was the best both performance and battery wise.

Just my personal experience
[Galaxy S II Original Android Development] frankcilo:
No, uc/uv script scales two cpu!

Virtual Oc not work very well with this kernel, it need also of uv script...but I use it for set sleep mod and wake mod (you can modify it changing value in folder "virtual_oc" in system/etc

https://market.android.com/details?id=com.tegrak.touchmove
[Galaxy S II Original Android Development] gokhanmoral:
thank you again :)

I doubt that this can also decrease heat because people are comparing the kernel to speedmod which has no overclocking option and therefore it uses 500mhz by default.
[Galaxy S II Original Android Development] littlepig877:
many thanks!!!!!
[Galaxy S II Original Android Development] Jodelaplaya:
The rc1 seems to be a bit laggy. But its ok. Good work again ;)

May someone send me the cmd line in echo, for checking if CPU voltages are correctly set please ?

Many thanks!
[Galaxy S II Original Android Development] hawkerpaul:
I have been rooted for some time now, and have been using this kernel since 1.7.2.

In the changelogs is says:

updated su to 3.0.4

changed rooting script. if you delete /data/.siyah/root-installed root will be installed again even if you already have su or Superuser.apk

updated CWM recovery to 5.0.2.3

I've just installed 1.8 and I still have CWM 4.0.1.5, and su binary v3.0

Do I need to delete /data/.siyah/root-installed in order for these new versions of CWM and su to get installed when I install the .zip?
[Galaxy S II Original Android Development] megazz:
I just installed the rc2 and it seems a little bit laggy. I'll check battery life.
[Galaxy S II Original Android Development] gusoldier:
For me also BIT laggy, rc2. I'm going to try do a wipe on cache/dalvik.
[Galaxy S II Original Android Development] hawkerpaul:
If you installed via .zip then this gets done anyway.

Just testing mine now...
[Galaxy S II Original Android Development] Vger1:
First experience:

Just flashed it...after first wake-up the phone froze (had to pull battery)

Maybe to many kernel flashes without clearing dalvik?
[Galaxy S II Original Android Development] gusoldier:
I installed the tar first. Now the zip (so everything is wiped), but the lag is still there.
[Galaxy S II Original Android Development] zikarus:
Compared to?

In my perception RC2 lags less than RC1. Quadrant is on par on my device. Lets see what the battery does this night...
[Galaxy S II Original Android Development] lpsi2000:
+1 and if it is adjustable, then I can make 1.7Ghz:p

Anyhow sounds like a good feature for future 1.9:D
[Galaxy S II Original Android Development] Sangrias:
Flashed tar file to Criskelo V22

Works fine no lags, no overheating.
[Galaxy S II Original Android Development] hausmanis:
wow finaly someone talks about battery, feels 99% talks about performance, who cares about numbers in a benchmark program not like sgs2 is slow by default, give me that long batterylife! that i have REAL use of
[Galaxy S II Original Android Development] HellRazorGod:
What I've noticed is there is sort of a graphical lagg with the kernel. Try playing asphalt or scrolling an app description quickly in the market or notice how fps fluctuates while quadrant is going on and graphics tend to jitter. Something with the gpu config maybe ? Please try and fix it mate. Thanks.
[Galaxy S II Original Android Development] Sangrias:
- signed :)

Not another SpeedMod Kernel, need Battery life
[Galaxy S II Original Android Development] gusoldier:
Ok flashed back to 1.8b2, lag is gone. I will do a report on battery tomorrow with pics and all.
[Galaxy S II Original Android Development] crypticc:
What do people mean by lag, no really, just waking phone up or generally like if I enabled the inbuilt system power save settings in 2.3.4 +? Just asking because maybe I don't perceive it, my phone waits for network, CPU not bottle neck for me.
[Galaxy S II Original Android Development] AdamHayton:
Rc2 not experiencing any lag here. Smart assv2
[Galaxy S II Original Android Development] lpsi2000:
@ gokhanmoral

Just flashed RC2 and it seems as su is being dropped in /system/bin and I thought you changed it where it was being dropped to /system/xbin?
[Galaxy S II Original Android Development] efegue:
Well, I wouldn't call lag, but sluggish animations. With RC2 even when using ondemand governor, it loses a lot of frames, I had smooth animations using this governor with the alpha versions and the FPS was stable when testing quadrant. Now it's unstable, so the animations tend to be sluggish because it loses frames.

Btw, I updated to KI8 and I lost root (expectable), but when I flashed back 1.8, I didnt have root. Had to flash CF-Root kernel then flash 1.8 to have root.

-----------

EDIT: just tested turning wifi on/off and to turn off it takes like 10 secs. I didn't had this with alpha 4 or 6 when someone reported this issue. I'm using KI8 stock now btw, I was using KI3 before.
[Galaxy S II Original Android Development] AdamHayton:
I'm also not getting any delay turning wifi on and off. Something has changed.
[Galaxy S II Original Android Development] crypticc:
I think there is an issue with radios from ki3 4 and 8. They don't like rebooting direct from recovery. Wifi and Sim connectivity is up the spout until I do a proper reboot. Almost without fail I can make it not work in way you said, and with missing Sim recognition at other times (depends if wifi is on at time of reboot). My point is are you sure it's the kernel and not just how you boot?
[Galaxy S II Original Android Development] OrangeDweep:
are those links up? I see file not found
[Galaxy S II Original Android Development] jdmcivic:
changelog states min gpu uv lowered to 800 but im still stuck at 900 while on rc2.
[Galaxy S II Original Android Development] hausmanis:

[Galaxy S II Original Android Development] xyzulu:
It's there, at the bottom of the first post.
[Galaxy S II Original Android Development] CA3iR0:
Yes, the wifi bug remains... It's not taking as long as earlier, but it's still there.

Sometimes it takes more time, sometimes it's instant, and sometimes I have to reboot the phone so the wifi turns back on... Weird stuff...
[Galaxy S II Original Android Development] Tsukihime:
i'm new here.

how can i use smartassV2 governor?

3ks.
[Galaxy S II Original Android Development] tomascunill:
Download voltage control app from the market, you'll be able to change the governor easy. The app is free and great, I started to use it yesterday and liked it over setCPU (which is 2 bucks). You'll also be able to undervolt if you want with it.
[Galaxy S II Original Android Development] androidkid311:
.... feel like an idiot lool! Thanks a lot mate :)
[Galaxy S II Original Android Development] Smoothface:
So I am using the AT&T version and was wondering if there is any sort of plan to bring this to the AT&T version yourself or through some other person?

From what I am reading this is an amazing kernel and I would love to see it available for my phone... Unless it is and I could not find something?
[Galaxy S II Original Android Development] marcadam:
I just had some weird behaviour phone got about 40% and then it suddenly rebooted. When it finished booting the home screen froze after loading only three icons and the battery now read 14%. Only a restore sorted this out. Has anyone else had this?

btw I was using rc1 when this happened
[Galaxy S II Original Android Development] AndreiLux:
Suspending of the phone still isn't 100% fixed (AOS bug, but this time in ninja modus). Just lost 5% battery in the last hour idling, 25 minutes out of deep sleep, out of which 15minutes at 800MHz, and that with the 200max offscreen profile. The processes don't show up anymore, but the behavior and drain of the AOS bug still prevails.
[Galaxy S II Original Android Development] coolfire:
Hmm... more to it than meets the eye? :o
[Galaxy S II Original Android Development] Vulpix:
My suspend still shows up in RC2 in betterbatterystats, just that it's not at the top of the list @ 99% anymore. Not using SetCPU.

---------- Post added at 08:51 AM ---------- Previous post was at 08:49 AM ----------

Probably, I'm not using any profile and my drain is at 1% per hour.
[Galaxy S II Original Android Development] cattleprod:
I'am 90% sure it's this commit

https://github.com/arighi/linux-gt-i9100/commit/efc29b1d4e0e3451f0b9a0654fae31869905eb26

that fix's the AOS bug as have applied it to my own kernel an since then Android OS has not gone over 10%.
[Galaxy S II Original Android Development] coolfire:
Hmmm.. Same here as well, bro. Wonder what is happening with AndreiLux's device...
[Galaxy S II Original Android Development] AndreiLux:
I think I'm going to start test-compiling on my own from tomorrow on, this is getting annoying.
[Galaxy S II Original Android Development] ZenithLM:

[Galaxy S II Original Android Development] cattleprod:
you will end getting annoyed at the samsung kernel some of their own code they added is just ****e and that commit is good example of it.

If your been annoyed at me for saying, what seems to have fixed AOS bug then sorry for that, I'am just sharing what I have found.
[Galaxy S II Original Android Development] mach0boi:
Is there a fix for the gpu voltage script not letting it go below 900mv? I set mine to 775,800 but it won't go down below 900.
[Galaxy S II Original Android Development] AndreiLux:
What? No. You're awesome, XCeLL is great ;) I just meant I'm annoyed at the issue.

I don't think it's fixed and only alleviated. That commit you showed makes no sense as to fixing the behavior I'm experiencing. Well it may well happen to other people but I'm the only one ****ed up in the head enough to monitor it the way I do. I basically reset the CPU timers every time I leave the phone idle more than an hour to check up on the behavior later.
[Galaxy S II Original Android Development] Vulpix:
Good luck! I hope you fix yours!
[Galaxy S II Original Android Development] cattleprod:
No worries, your not the only one who monitor things the way you do to ;) but I'am doing the opposite an leaving the phone alone for two hours or so (an that hardly happens).

I have applied a few patch's to my kernel and that's the only one which seems to make sense to me, as checking in linux kernel that code not there nor is in my desireHD kernel too.

EDIT nice find on the touchscreen locking the cpufreq at L3 also added that to the kernel ;)
[Galaxy S II Original Android Development] stifmaister:
Hi,

thanks for this kernel...it works great, apart one issue:

my phone has NFC built in , and it seems like it gets disabled when the device goes in deep sleep. Is this something easy to fix?

I use my phone everyday to pay in shops and subway in Korea, and with this Kernel, I need to turn the screen on, to be able to pay by NFC. IF i use the stock 2.3.5 kernel i can just tap the phone when is completely sleeping.

It's not a big deal but it would be cool if it was an easy fix:)

Thanks again

Sergio

[Galaxy S II Original Android Development] aqualeris:
Voltage control or setCPU? Really confused on which to use after reading about some users claiming setcpu is consuming more than it saves battery.

And how do you undervolt the GPU?

Thank you so much!
[Galaxy S II Original Android Development] Denwa:
Just tried the 1A charging script while using mhl. Still see drain istead of charge.

This leads me to believe that either the phone is seeing the mhl power as usb and is setting it's cap at 550mA (instead of 950mA) or the mhl units are using a ton of power.

I suspect the former is most likely. That 1A power script only effects charger power, not usb, correct?

Is a script possible that forces "charger" power when tvout is activated? I know little about scripting.

/EDIT. Never mind. I reflashed the script and I an getting diff results so I nay have had a bad script flash.
