[Galaxy S II Original Android Development] Entropy512:
I'm fairly certain that the regulator voltage doesn't matter once you actually hit deep sleep - it only matters in that last 150 msec before sleeping and the first 650 msec or so when resuming.

If I recall correctly, most ARM chips have a final "on/off" regulator control handled by a hardware discrete - the voltage gets set when entering suspend, but the last thing the CPU does before actually sleeping is to shut off the main regulator using an I/O discrete that isn't controlled by software (or, if it is, is buried deep in the suspend code).

I guess the question is whether deepidle is inhibited during suspend/resume - if the CPU can hit deepidle, entering suspend at 500 MHz may not really buy you anything.

A kernel compiled with Android v2.3.x sources will not work on a v4.x OS, or at least not without major issues.

You'll have to stick with whatever kernel you get with ICS in the meantime. There will be a rooted ICS release within hours (minutes?) of it being available anyway.

Quick question gents: I have my init.d setup to load 200~1400 at bootup with the following:

echo "200000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

echo "1400000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

However, when I check Voltage Control afterwards, it's only 200~1200. So, why is it not properly loading the init.d frequency range on bootup?

Thanks!

Hello,

Ever since I installed 2.5 and I try to restart my mobile device - it justs re-resets all the time. Like if I reset it it boots for a 2-3 seconds, goes to home screen, blinks and goes into boot again without asking me for pin.

This happened before to me with using this Kernel but not when I'm restarting.

Gonna flash 2.5.1. right now to test it.

Anyone knows why do I experience such problems?

EDIT: And I'm not only one but when I try to clear Dalvik chace then I got this message "E:unknown volume for path [/sd-ext]

Thanks in advance.

EDIT:

It seems that every time I set up my alarms and I try to restart my phone THEN it goes into this kind of "bootloop"... hmmm?

Oh man, you rock! Did a search for this but couldn't find it being discussed. Worked perfectly, many thanks!

*Might be happening because of the undervolting settings or it could even be something else unrelated to the kernel.

I don't know if anyone else is experiencing this but on the last few releases, after boot up...

1. The Wi-Fi indicator always shows one bar. If I then switch Wi-Fi off and then on again... it shows a full 4 bars!!

2. Again, after boot up, if I go to Gallery and try to play a video, it will not start. I have to press the Home button and then go back in to Gallery and the videos will then play fine until the next time I re-boot.

It doesn't happen on all Siyah kernels I've used but more so on the recent ones. It seems that both Wi-Fi and video do not boot properly. Doesn't happen with other kernels I use with CheckROM v4. Am using no Profiles or U/V. Have tried clearing the Gallery data but that does not help.

Any suggestions please. :confused:

[Galaxy S II Original Android Development] pay.c:
@gokhanmoral:

There seems to be a little bug in core voltage control: Right now, I am measuring the currents for different system and CPU states (I will do something similar for the SGS2 as seen here: http://www.android-hilfe.de/root-ha...ku-infos-ladekurven-leistungsverbraucher.html and http://www.android-hilfe.de/dell-streak-forum/91013-info-akkuverbraucher-des-dell-streak.html ; both in german only, sorry for that (just like use Google translator if interested ;) ).

When I changed core voltages for different rates (200 MHz, 1000 MHz etc.) current (or power) varied nicely along with core voltage (core voltage up at constant CPU rate -> current/power went up when CPU is at foll load). The only rate where this did not happen at all was 500 MHz.

As it would be kind of amazingly awkward that at every other rate power varies with core voltage but not 500 MHz, I assume that there could be a typo or similar in the source code, which prevents the core voltage at 500 MHz to update.

Best, pay.c!

PS: Is there a possibility to change internal voltage in SiyahKernel?
[Galaxy S II Original Android Development] poofish:
I've been using Siyahkernel for quite a while now, and generally never had any persisting problems that haven't been rectified by an update.

However, one issue I've noted since a few revisions ago, probably since like 2.1 or thereabouts, is that when calls come through, it now takes significantly longer for the screen to turn on so I can actually pick up the call. Before, the screen would turn on the same time the ringtone starts playing. With the recent builds, it takes about 2-3 seconds before it turns on.

I generally run 200-1200, sio + lulzactive, with minor undervolting so underclocking isn't the issue here. The rest of my phone runs smoothly, and I have no screen-off profiles either.

While this doesn't ruin the kernel, it does cause annoyance for me. Is there a way to fix this?

I beg to differ on this one: it's their job as XDA members to search, search again and then post a question. Nearly every question asked day by day in this thread has already been answered (most of them again and again). I do test the search function myself, even if I know the answer to the question just to see if it is possible to find it. Guess what, 90% of the time I do find it!

And don't get me started on the whole "I didn't read x pages of the thread, so please excuse me asking"... that's just advertising in big, fat neon-sign letters that you didn't searched because if you search, you don't need to read the whole thread.

All in all, I don't think we have to support the lazyness of some of the members of this forum. And a simple reminder to use search isn't that harsh in my eyes, it's just a reminder of the rules of XDA (don't make me get out the xda noob video to proof it ;) )

Is there a chance for "fixing" this problem or is it impossible? :confused:

I had been running this kernel too at the time and it was indeed the best around by far when it comes to battery life. Sadly he didn't update it afterwards so it fell behind on features and also haven't heard from him again. One could ask him for the source code.

One could argue that one of those things he undervolted was the omnious "internal voltage" that the Tegrak app also uses. I'll be skimming the source code myself to see what one can find.
