[FIX] Dual Core always appears to be on OR off, governors default to performance.

[freeza]

Maybe some of you on custom ROMs have noticed that your second core functions strange, which would also mean terrible battery life and abnormally hot phones.

Well, this is due to something causing the cores to switch governors to "performance" upon boot. The only way to fix it is from a script or other app that controls CPU. That's not all. The second core seems to not function according to specs. It will either always stay on, or always stay off. mpdecision doesn't appear to work properly.

Well, I've narrowed this down to "samsungani" and "samsungpowersound" which are located in /system/bin/. Removing these at an attempt to get custom boot animations working and to get rid of boot sounds are what's causing the funky core behaviors.

The fix is to restore the two files and chmod them 755 as well as chgrp to 2000 to get them back to the way they're supposed to be.

I'm not sure if any of this effects custom kernels but it sure does on the Stock kernel.

The file I uploaded will restore the samsungani and samsungpowersoundplay files to /system/bin/ as well as copy over silent PowerOn and PowerOff sounds.

This is a awesome catch thank you very much. This may be a stupid question but can you provide a zip to fix this or do we need to do it through file explorer and if so can you give us a tutorial on how.

Sure I can provide a zip, give me a bit.

Does this do anything to the cpusleeper app (eugene)? Not the script, but the actual app for those who have it installed? Will the zip you provide defeat the need for the app? Thanks for any additional info!

Nah, the zip will only be adding those files back to /system//bin/ if they were removed, like in order to get support for custom boot animations.

Is it "samsungpowersoundplay" ?

Hope your not asking for an Eta if you read the five post he said give him some time he is doing this for free. This is the number one rule on xda when you see the zip in the op then you know its done. Not trying to be mean but you will get flamed for asking a question like that just trying to help you out

Does anyone know if their is any negative effect on blazer 1.6 ?

Havent had any issues so far. Good to go imo.

Yes



Thanks man

Just flashed it rom definitively seems alot more responsive I was seeing the lag and just had some plain weird stuff going on glad we have a dev lime you to find stuff like this and squash it. Do we need to flash this after we flash a rom obviously your rom will have the fix so I'm not worried about it but for others who arent using your rom.

Edit: is there any way I can test to insure both cores are doing what they are supposed to be doing like an app per say

Well, it really only will matter if your current ROM includes a different boot animation and/or removes those files. In any other case, it will do nothing.

OK thanks again love the rom I know you get asked this a lot but if you ever need a tester let me know I use to test for mijuah but my son stole my s2 so I'm bored now lol.

Zip applied, and I had to duplicate the process to confirm what I thought I saw:

Been running blazer 1.6 for a few days now and I honestly don't know what (if any) boot animations are built into that rom, but in the spirit of testing (and flash addiction) I used this zip.
This is what I noticed (and duplicated to confirm)--

Chainfire's live dmesg/logcat (I used paid versions) were replaced by this zip file.
When I "reinstalled" the first attempt found no boot animation files. I attempted install again and this time it did indeed "repair" the logcat/dmesg boot screen.

This is my first dual core so I have no experience in these apps working or not on such phones.
If this is wide spread then perhaps chainfire might want to look into an update to his code, if this is specific to the sgs3 then maybe we have deeper issues to delve into.

Sprint...LF9...Blazer1.6...no other customizations
