Psycho effect, since 0 will use more cores than 1 or 2... are more battery friendly than 0.

More infos : https://wiki.linaro.org/WorkingGroups/PowerManagement/Specs/sched_mc

Update :

After discussion with Many40, i gaeve some details : in Force Dual : 0:Bad, 1:Good battery 2:Good performance

In Hotplug mode going for 0 will let the hotplug module do the job. You can use 1 (this mean load balancing regarding tasks) to save some battery but i do not know if it has advantage on the exynos.

Everything Explained

About the 520mHz step and the matching voltage, just experiment... and if your phone burn... gave us the info.. :D

More infos : The GPU in SGSII is a Mali-400 4 Cores : http://www.arm.com/products/multimedia/mali-graphics-hardware/mali-400-mp.php

Keep in mind that this is not physically the same GPu as the S3, this last one is highly overclocked and i've read that it is 32nm instead of 45nm for the S2.. So you will never met the S3

Pegasusq is certainly the most advanced governor... use it.
[Galaxy S II Original Android Development] OssiB:
I dont think it will burn! ;) but the gpu will take damage i think.even now with 440 mHz it gets smoking hot!but its stable and the performance is awesome!
[Galaxy S II Original Android Development] galangdj:
Sorry for the OT. But I would like to ask if anyone can post here the default profile of Siyah? Also, if you have some tweaks as well to save battery, would love to. Thanks. :)

I'm unfortunately contributing to spamming this development thread but I couldn't withstand any longer if someone misinforms the others about sched_mc (it's more complex issue than you think). You definitely need to read more:

I seem to be having a problem when I charge my phone from the wallsocket it's usually about almost empty under 15%. I plug it in and it charges like from a usb cable aka 450mA if I unplug it and plug it back in (same wallsocket) it charges normaly with 650mA.

Could anybody else test this out and let me know plz??? Maybe it's just an issue with my phone or my charger or if anybody else experienced this.
[Galaxy S II Original Android Development] arroba3:
Hello!

I've been using Siyah's Kernel for really long time, trying to have the last version everyday. But I do have one complain: I'm using the stock ICS 4.0.4 (XWLPY) rom, and whenever I try to move my apps to the internal sd card (aka usb storage) it send them to the external sd card to a folder called ".android_secure". This wouldn't be a problem if I have a few apps/games in the external sd, but I have plenty of them, making my telephone's boot time really-really long. The thing is that I've been investigating and I think I've found a solution, but it requires to change a line in the init file of the boot.img.

Yesterday I spent the whole day trying to extract my boot.img file (which I had taken from CMW recovery) but I was unsuccesfull. So, could someone with more experience than me, please make that modification at Siyah's last kernel? This is what I want to add (the two bold lines):

# Directory-target for where the secure container
# imagefile directory will be bind-mounted
mkdir /mnt/secure/asec 0700 root root
[B]mkdir /sdcard/.android_secure
symlink /sdcard/.android_secure /mnt/secure/asec[/B]

Thank you very much!:good:

P.S.: Sorry for my English!
[Galaxy S II Original Android Development] OrangePL:
Hi,

After flashing 5.0.1 I have a problem with applying any tweaks via the STweaks or ExTweaks apps. Changing anything manually and restarting the app results in the change being reverted to previous (default) state.

Also, overwriting the default.profile in /data/.siyah with a modified one or reverting to defaults and overwriting again does not result in anything changing.

Additional details:

- using Thunderbolt! 2.8.0 scripts

- both apps have SU granted

- .siyah dir and .profile files have full permissions

- tried fixing permissions and cache wiping, re-flashing - did not help

- ROM: WanamLite ICS, UHLPS base
[Galaxy S II Original Android Development] Mr.Greg:
Seems like GM will close this thread again, coz people still don't know wher to post a nondevelopment question.
[Galaxy S II Original Android Development] Eagle3386:
+1 for that.

Regarding 5.0.1, just a small hint in case someone else experiences this: a couple of CM10-Nightlies ago, I noticed that although Apollo was working fine (with and without headphones connected), I did not hear any mail-, message- or ringtone-sound. While on vibration, everything notified me correctly, though.

Solution: Re-flashed CM10-Nightly, cleared cache-partition and Dalvik cache, booted CM10-Nightly, rebooted into CWM-Recovery, re-flashed Siyah 5.0.1, cleared cach-partition & Dalvik cache once more, booted CM10-Nightly and: still no notification sounds!

Launched STweaks, reduced Speaker amplification from 20 to 0 and finally got sounds back - even when the value was set to 20 again.

But I adjusted it to 10 - just in case.. ;)

[Galaxy S II Original Android Development] Entropy512:
You obviously understand nothing about how suspend and resume on Linux works if you think it is that simple.

Messing around in suspend/resume code is VERY easy to screw up. Trust me, I've messed around in it before and the usual result is - SoDs. It also often depends on an understanding of how each device enters suspend/resume, which is documentation we don't have for many peripherals. (In Gingerbread, nearly all of the resume time was waiting for the modem. I haven't checked for ICS, as I've had much higher priority issues like preventing the damn kernel from crashing if I use SetCPU or any other clock control app..)

Undervolting, on the other hand, is just exposing the voltage table to sysfs. It's simple code and easy to implement just by reading the code.
[Galaxy S II Original Android Development] rauschkugl:

[Galaxy S II Original Android Development] blumsen:
Can't claim that I read every single page, no. However I think there is a difference between on the one hand getting unsatisfactory results or simply insignificant results when overclocking (then you assume that either the overclocking is just not working, or the test cannot measure in a valid way). But how do you explain that I get LOWER scores when overclocking? that was my point in posting my observations.
[Galaxy S II Original Android Development] rauschkugl:
and that exactly was written not more than 5 pages before you asked. that's why i said it. it's a known problem and has widely been discussed.

You use current widget, as per the change log.

As far as increasing charging speed, by default the chip used in the SGS2 only supports two modes, 650mA and 450mA, someone was talking about maybe trying to use the other chip to charge the phone (more charging modes afaik) but that was a long way off at best.

Flashed b5 on the Disaster ROM v.9 (LSD) after using the hawkerpaul's kernel wipe script. Everything seems to be working fine (like mentioned by previous posters). It's great to be able to use BLN again! Could not trigger bootloops or boot hang-ups (tried battery pulls and power button long press). Updated STweaks to 1.1 from Play Store.

Boot time subjectively feels faster, compared to Jeboo (my previous kernel) or PhilZ (but I didn't time it, so can't say for sure).

Very happy to see Siyah kernel development again! :)

Hi Gokhan.

Thank you so much for rejuvenating the S2 scene for me (and no doubt many others) since you were kindly donated an S2. :victory:

As for Beta5, so far everything has been working perfectly for me (no SOD, wifi/bluetooth/camera/video all working as expected) and no bootloop issue on power off.

It may be placebo, but to me beta 5 seems smoother than beta4, and any other JB kernel I've tried so far. I've not noticed one single lag during use.

Keep up your brilliant work for our S2's.
