When I actually went through the source to search for the GPU hard-coded voltage minimum, you could also see that the ARM cores were also clearly designated a separate step-down converter on the MAX8997 power management IC. I'm 99% sure that lowering CPU voltage will have absolutely no effect on anything else.
[Galaxy S II Original Android Development] :
as I already said and I am no expert really, I just stated my experience.. maybe it's just placebo, but going too low with UV causes higher battery drain (on 3 different HTC and 2 Samsung devices).
[Galaxy S II Original Android Development] jim-bo:
If you go down too low, below the lowest level that the cpu/kernel actually supports, then it will often set it back up to default, which would appear to give a sudden jump up in power consumption. That could be what you are seeing.
[Galaxy S II Original Android Development] Orka82:
I had the same problem with wifi but i just reflashed the kernel and it worked after that. Same rom.
[Galaxy S II Original Android Development] ringrover:
mate

in final 1.8 you go back to CWM 4.0.0.2 ....why ?
[Galaxy S II Original Android Development] pachinkosan:
tried everything, 1.8 not working, not bootin and cwm doesn't work

back to b4, it's awesome at all

release for me was with b4
[Galaxy S II Original Android Development] tomascunill:
I had that same problem but with 1.7.7 and never had it again. Now with 1.8 my wifi is working perfect. Toggle from status bar and everything is OK
[Galaxy S II Original Android Development] jim-bo:
Because 5.x.y.z is still in development, and people were reporting problems restoring backups from it, which is kinda BAD for a non-beta release?
[Galaxy S II Original Android Development] yhrn:
Running 1.8 (upgraded from 1.8 rc2) on stock KI8 for a little while now. All good so far (including wifi), but I haven't tested that much.
[Galaxy S II Original Android Development] :
because it is most stable one so far.

well it is not, but okey.. lets move on, to each his own :)
[Galaxy S II Original Android Development] mccune:
Indeed.. problem was solved by installing: su-2.3.6.3-efgh-signed.zip

The first time I flashed back to 1.7.8 I didn't have any problem. Flashed 1.8 again and the second time I flashed back to 1.7.8 I lost root.

So at this point I have root back but WiFi toggle stil doesn't work.

Here is what I did after losing root:

1. Reflashed Siyah 1.7.8

2. Flashed su-2.3.6.3-efgh-signed.zip (to regain root)

3. Flashed Siyah 1.8

4. no luck

Edit:

5. Did a second soft reset after flashing Siyah 1.8.

6. All WiFi toggle seems to work!
[Galaxy S II Original Android Development] :
sorry to hear, if you have time, backup, try clean install of ROM and kernel.. should work. take care.

---------- Post added at 06:32 PM ---------- Previous post was at 06:29 PM ----------

I was testing the smartassV2 governor and for me it's working smoother than in 1.7.8 which was a bit laggy. As for battery life I can't tell anything yet.
[Galaxy S II Original Android Development] :
Flashed few rc's and final today. Not bad :p

Hello

in V1.8 RC4 was CWM 5.0.2.3 integrated, why is in the Final Siyah v1.8 the old Version of CWM 4.0.1.5??
[Galaxy S II Original Android Development] Jeks0234:
wtf, don't working

Flash KI3, but no effect, flashing 1.8 and phone freez at Galaxy S2 and yellow triangle... this problem not only at my phone

what to do?
[Galaxy S II Original Android Development] tomascunill:
This was answered twice in the last 2 pages...

It's because people have reported problems with 5. versions of CWM. THe stable version of CWM is 4.0.1.5, so since this is a release version, stability was the main concern, and becasue of that a stable verion of CWM was used.
[Galaxy S II Original Android Development] mariosraptor:
No undervolting. As it was.
[Galaxy S II Original Android Development] :
Flash ki3, flash cfroot ki3 via Odin, flash stock kernel via Odin. Flash cfroot ki3 via cwm app. Flash 1.8 via cwm app. Always reboot twice. Should work.
[Galaxy S II Original Android Development] aeroman:
I have no Problems with Siyah 1.8 RC4 and the CWM 5.0.2.3 and a will go back to Siyah 1.8 RC4 with CWM 5, i Like the Blue Color from the CWM 5.0.2.3. Or is it not stable?
[Galaxy S II Original Android Development] tomascunill:
I don't think it will bring you any problems, but anyway the blue colour won't benefit you at all. I think the biggest problem is that you won't be able to use the CWM manager app or leomar's kitchen app, since people reported that those apps were not working with CWM 5.x.y.z
[Galaxy S II Original Android Development] pac213:
I strongly suggest you stick with the stable release. :)

GPU is graphics processing unit and just like CPU it can be overclocked (both over and under) and undervolted...

CPU gibi grafik islerini yapan chipin de voltaji veya frekansi ile oynanabiliyor artik.

[Galaxy S II Original Android Development] Zanr Zij:
When I increase voltage @ 200MHz ( from 800mv to 850mv ) and 500MHz ( from 825mv to 850mv ), 1.6 very stable with smartassV2 scaling. Still testing and finding some setting for best battery life :). Thank you again ;)
[Galaxy S II Original Android Development] gokhanmoral:
I forgot to answer this today...

you can change the i/o scheduler by using no-frills cpu manager from the market.

it can also be used to change clock speed and cpu governor. those who don't need to change voltages may use that great app...
[Galaxy S II Original Android Development] Остап:
Please, unswer :cool:
[Galaxy S II Original Android Development] gokhanmoral:
I didn't understand the first question, but the answer to the second question is "I don't know" :)

since I don't use BLN as it causes wakelock, I don't know if it is possible to disable it for gmail.

there should be a build.prop parameter or something to disable it. I did not compile the liblights or modified it in any way. maybe creams can answer this question if he has a thread about BLN modifications.

Hi, is there a problem if I do too much undervolting?

My stable settings are:

100mhz-825mv
200mhz-850mv
500mhz-875mv
800mhz-925mv
1000mhz-1025mv
1200mhz-1125mv
[Galaxy S II Original Android Development] gokhanmoral:
no. if it is stable you can keep voltages as low as possible.

your settings are similar to my previous settings and I wasn't having any problem.

I am now staying at stock voltages during the development just to be on the safe side.
[Galaxy S II Original Android Development] Остап:
would u please publish the stock values ?

[Galaxy S II Original Android Development] ussittette:
Go back some pages, you'll find your answer ;)

Btw, I'm on 1.6 and didn't have any issue yet.

For what I have seen, battery is much better for me than on 1.5

[Galaxy S II Original Android Development] gokhanmoral:
Lots of batista rom users have the same problem. It seems that my kernel doesnt support that rom. Try to clean cache and dalvik and remove init.d folder alltogether. Maybe it will help.
[Galaxy S II Original Android Development] cbeckstein:
CWM 4.0.0.2 is the specific version of CWM that Chainfire distributes with his CF-root Kernels --- with special patches for the SGS 2 (see the XDA CF-root Thread where Chainfire explains that)

probably the best choice for a CWM on the SGS2 version one at the moment can make

it is not really comparable to the "old" unpatched-by-Chainfire 4.0.1.5 or the "new" and (I am sorry, reports in this thread show it) still buggy 5.0.2.3 unpatched-by-Chainfire version

and coming from 5.0.2.3 it also is not a downgrade in the stricter sense --- more of a sidegrade :-)

I am glad Goohkan chose to replace the CWM by the proofen SGS2 tailored 4.0.0.2 of Chainfire, believe it was a wise move
[Galaxy S II Original Android Development] pachinkosan:
renewed my firmware from ki3 to ki8 with all wipes, factory reset etc.

1.8 still not working

i'm dissapointed.
[Galaxy S II Original Android Development] aeroman:
O.K now I'am be happy about CWM 4.0.0.2 Version, why the Back Button works again in the Recovery Modus. ;)
[Galaxy S II Original Android Development] dandroid13:
a2dp sometimes "lags" with 1.8 under 100MHz. I believe that with older versions it wasn't (can't remember :p).
[Galaxy S II Original Android Development] rauschkugl:
this is not really true. someone reported that they will work when you install them again. i use a german rom that isn't on xda and it has also a backup solution integrated in the system menu. had no problems with cwm 5. the only problem is that the backups will be stored to external sd but you only can restore from internal sd so you would have to copy the files from external to internal before restoring. no other problems with cwm 5 for me.
[Galaxy S II Original Android Development] L0cutus:
for me v1.8 seems ok, no problem till now.
[Galaxy S II Original Android Development] cbeckstein:
right, someone reported... and this guy was wrong...

I have reinstalled and tested all three of the Apps that communicate with the recovery --- CWM App, DarkyROM2 and Kitchenrom App Pro; none of them works correctly with the 5.0.2.3 recovery on my stock KI8

the only App that correctly works with 5.0.2.3 on the SGS2 with KI8 is the ROM manager (it better should, because it is from the same author)

the 5.0.2.3 is working fine when you boot into it and do your stuff there manually, yes, but the recovery specific Apps most of us use, do not yet play correct with it

how it is supposed to work the battery calibration script ?

[Galaxy S II Original Android Development] :
Did you follow my instructions with cfroot? Also redownload 1.8 using different browser.
[Galaxy S II Original Android Development] :
Just leave your phone on charger over night. Turned on not off. That's all.

If you have used another version, remove /data/.siyah/battery-calibrated, reboot and keep connected to your charger for ~5-6 hours.
[Galaxy S II Original Android Development] 2bullish:
Ive given up on this kernel until we get less than 2 updates a day. What is the point of testing when a "new" version is out within hours. Add to that we have no idea what has been changed!

Anyways, nice kernel but I'll wait for the full release, no doubt 1.8.9.1.9.1.9.1.9. jeez :confused:

Nice work Gok but your hourly releases and lack of change log are a big no no, as some of us actually use our phones, as well, phones.

[Galaxy S II Original Android Development] jdmcivic:
im just hoping that the problems faced by some people here are not caused by the new clockworkmod recovery when they flashed the rc4..
[Galaxy S II Original Android Development] rauschkugl:
well but mine also worked without doing anything. and i'm sure that it's not rommanager that's built in in the rom that i use.

[Galaxy S II Original Android Development] rauschkugl:
i don't care which recovery to use. just said that the new version isn't that bad that users have to be kept away from it if they want to try.

true, but there are always unlucky ones. you can't make every single person happy. as said, i don't care which recovery is built in but if somebody wants to try the new versions there's no reason not to do so. not everybody uses leamars kitchen or the cwm app and will have no disadvantages.

Siyah Kernel 1.8 installed. I had to update manually SU version 3.0.2 to 3.0.4 version from the market , since I had kept the 3.0.2 version I had installed. Attachment 3 screenshots. The first is the screen that indicates the kernel is installed. In the second and third screenshot I see a problem. Why the time at the top indicates the battery time and time below indicates 0 seconds?. Until the battery does not lose 1% of load, the down time does not change and remains at 0 seconds. Is this the case or is it a bug?

[Galaxy S II Original Android Development] gokhanmoral:
wow, pages of posts :)

I cannot answer them one by one.

here are some answers, pick the one you like:

- sources are huge because I put everything in it. lots of people sent me pm about sources. so here they are :)

- I don't know why the kernel doesn't work for some of you. someone said that rc1 was working. I can try to see what I changed since then. however, if nothing since alpha6 worked I doubt I can help.

- you don't want to flash every version. when I have time, I fix and release new version. If you are not comfortable with this many of releases and make this a reason not to use this kernel it's fine. but it will not change. I will release new version when I have time to make a change.

- There are still people who is waiting for the stable release to flash. I am not Samsung.. if nobody tries and reports problems there will be no stable release. if you are one of those who flash v1.8 without flashing any release candidate think about this...

- I will concentrate more on the performance and try to solve some weird "I am unable to run your kernel" problems. however, I will be quite busy this week. you can still download v1.6 and 1.7 using the link in the first post.
