http://cgit.openembedded.org/openem...0002-cpufreq-introduce-hotplug-governor.patch

it is not new...

I have added it because people were asking for abyssplug..

I do not like people changing governor names after some tweaking and imposter themselves as if they are the author of that governor...

I didn't like the governor too much. I think pegasusq can perform better...

but test it and see for yourself. maybe you will like it...

TL;DNR: Toggling GPS and Aeroplane mode doesn't work.

Thank you for replying and I'm glad you don't have any issues. Basically the GPS toggle button is either frozen on or off but all other toggles work and sometimes aeroplane mode does not take effect when toggled. Other than that everything works well. Thanks again to anyone that can help :)

Ps: cpu/gpu uv, uc, cpu governor etc do not seem to have any effect but stock kernel or cf-root restores toggle functionality if flashed. This issue has also persisted across all stock ICS builds I have flashed.
[Galaxy S II Q&A, Help & Troubleshooting] rlorange:
OK so I've tried both Hot plug and Pegasusq and I do feel peg is superior especially how GM has tweaked it in 3.2.5.... then again hot plug is just ondemand with 2nd CPU awareness and I never liked ondemand personally.

hmmm,...thats curious...I did have that issue this morning when the phone was charging overnight. I have 'tasker' app which turns off the phone when battery-full is reached, so I thought that was misbehaving, and didn't mention it..

maybe it could be charging related

flashed yesterday, all default, pegasusq, no undervolting whatsoever

I did realize 'force 2d gpu-rendering' was set after reading up this morning and turned it off, but maybe it's not related ; will have to see how it holds up the next couple of days...

Hi, anyone having wifi problems after flashing a kernel should not use cleaning scripts before flashing the kernel because the script wipes the wifi modules, I'm surprised that this hasn't become clear to everyone. I've stopped using cleaning scripts for about 2weeks now and I haven't had a problem with wifi at all with any siyah kernel, stop blaming the devs.

Flash it as tar via Odin or boot into recovery and flash the zip via clockworkmod.

It will only flash kernel and will not affect your ROM or data
[Galaxy S II Q&A, Help & Troubleshooting] tuniel:
Just download the cwm version, copy it on your phone, reboot in recovery and install zip from card (either internal or external, depending on where you did place it).

As an alternative you can use Odin to flash the tar version.

don't worry, flashing a kernel will not affect in any way your rom :)

by the way, you might consider to upgrade the rom to a newer one (LPG/LPI, they're both 4.0.3 and fix quite some stuff that are odd in LP7 - i did it and didn't lose anything...)

good luck

edit: rakeshishere you were faster than me!

Anyone experiencing vibration drop issues with 4.1.3?

Issues with Siyah 4.1.3 and "Missed It!"

EDIT: Never mind! Not Kernel flashing messed it up, but something after making a nandroid. Got it running again!

============Original Message==========

Hi everyone,

Is anyone here using the notification widget Missed it! by igece.labs and experiencing problems after flashing Siyah v4.1.3.?

After rebooting, on widget initialization, Missed it! checks for its license. The homescreen widget says "checking license" before it shows the actual widget, which takes a few seconds. After flashing Siyah 4.1.3. I get an error in the Statusbar that die license could not be verified. Restored my backup, evrythin fine. Flashed 4.1.3 again, same problem.

Really strange, any idea what could cause this?

Unfortunately I have no further information on how Missed It checks its license and where this license is stored.

I would contact the developer if I had any clue on what could have been changed with v4.1.3 that could cause this.

Lagg with charger!!?? sgs2 kernel

hey i just updated my kernel from 4.1.1 to 4.1.4

the number one and maybe only problem after doing that is that when my charger is plugged to the phone it is lagging very MUCH !!!! and even if i revert back to a previous version of the kernel from 4.1.4 to 4.1.1 it still lags when it is plugged to the phone.

i tried reflashing the rom with 4.1.1 kernel and the problem is still there,

BUT when the phone is unplugged to the charger it runs very well on both 4.1.1 and 4.1.4 it has never been faster..

so my questins are why does the problem remain after reflashing and changing kernel. and why did the problem even accure and why did it kind of stay? thanks for any answere that might help !

i really love siyah kernel it is the best in my oppinion ! :D keep up the good work!

EDIT : lol now it is working properlyi think... but if anyone of you have any answeres please share ! :)

If you would like to have only two steps eg 100 MHz and 166 MHz, set 1st step as 100MHz, 2nd as 166MHz and other two whatever you want but also you have two set GPU tresholds "2-UP" and 3-UP" as 100% so that first two steps will be used but two other (3rd and 4th) will never be active.

I just installed the newest kernel from siyah but I just don't get as much battery life with Paranoid Android 2.1 as the previous combination.

Maybe you guys have the perfect settings laying around for this specific kernel+rom combo. I just don't really know all the extweaks option. Like schedulers and stuff. I sound like a noob I know but the last time I overclocked a phone was my htc hero.

I don't think it's necessary to overclock this phone but my 2000mAh battery is acting like a normal one.

[Galaxy S II Q&A, Help & Troubleshooting] Frozenthunder:
And you mean that this has been the case with earlier versions? Why would you do that? The temperatures which you can reach at 1200mhz are fine since Samsung designed the hardware to run on that frequency. No need to down throttle at a certain point, that thing can run 24 hours at 1200mhz on 100% usage. Or am I missing something?
[Galaxy S II Q&A, Help & Troubleshooting] LMBBananaJoe:
you just installed kernel, didnt you? How can you tell about battery life then?

In clockworkmode you can choose battery profile for siyah.

IMO default options are good! Screen consumes most battery, so you can adjust gamma in extweaks to have it less bright/more battery friendly.
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Nope. If you're running 1.2GHz for 24 hours, your battery would've drained even when plugged into a charger. You wouldn't last 3 or 4 hours with it even with the charger plugged in.

I'm not sure if GPU had something to do with it, but I can confirm that CPU has a down-throttle before this. Not sure why it failed to activate this time around.
[Galaxy S II Q&A, Help & Troubleshooting] Frozenthunder:
nah, my battery lasts 24 hours at least when I got heavy usage :D

or maybe it was just the governor which down throttled the CPU a bit for other reasons and now it doesn't do that anymore because it got tweaked?

never heard that ur phone down throttles due to temperature. I've used my phone in 37°C+ environments on RR before and it was just as smooth as in 20°C environment
