As far as I can imagine every Governor does exactly this (or at least changing HotPlug to second allways off) coz when you think of what is DeepSleep, the answer is:

Going to the lowest possible frequency -> which means second core isn't needed.

That is how I think about your idea.

But let's see how DorimanX thinks.

BTW - wouldn't changing the Governor at every sleep/wake consume much more battery/produce more "lag" as it would save? :confused:
[Galaxy S II Android Development] johnbeetee:
​

1. Great idea :) ...but it used to be in cortexbrain a while ago and got cleaned out ; besides, once you turn of the screen, pretty soon (unless something keeps the phone awake) the system goes to sleep and uses the least energy. I think it's more important to facilitate the phone to go to sleep as soon as it can, when screen is off, and leaving secondcore on, and let it finish it's tasks readily helps with this.

2. Can't really agree on that. Tasker uses at most on a whole charge about 3-4%, and I got it doing a lot of crazy things, from doing a lot of settings on boot, determining whether I'm home or not (wifi vs mobile data), turning on data every 15 min. and syncing, tweaks on screen on, tweaks on screen off,negative screen using certain apps and proximity sensor, determing ideal gamma_shift on screen on, etc.etc.

Besides that, Extweaks only runs when your using it, Once closed, it can't interfere or cause lag (maybe only the first 20-30 secs after closing when it's updating the profile). And believe me, if it was draining a lot, I would of ditched it a long time ago, even though I bought it :laugh:

I must say, a bit OT, but tasker is the best app ever for me. You can even program stand-alone apps with the latest version :cool::laugh:

3. That sounds great! :) if this person has an open git, or thread with maybe scripts, just point me in the right direction ; chances are these tweaks may already be present in cortexbrain, but just need some other values :)
[Galaxy S II Android Development] marbulas:
Just get frequency as low as avaliable can save battery too but it makes lag when playing music in deep-sleep :(

(This is why the cpu governor lulzactive2's default frequency of deep-sleep is 500Mhz)

And turning off another core is much effective to save battery than getting down frequencies.

Before I realize about this I thought like you either :D
[Galaxy S II Android Development] johnbeetee:
not really, and it does help a bit saving energy ; been using that for ages, when I was using siyah and before dorimanx came into the picture, using a modified script based on the construct also used in Thunerbolt! scripts of member Pikachu01 for screen-state scaling. Used pegasus/conservative with my own set of parameters. consumes almost no resources at all
[Galaxy S II Android Development] marbulas:
3.

The forum he is in does not support English(only my mother tongue) so you can't contact with him...

I'll contact him instead of guys who can't contact because of language and want to contain his work when dorimanx has a concern about this :D
[Galaxy S II Android Development] voku1987:
1.) We can only use deep-sleep if there is only one core up ... so I think it's a good idea, but wie have already tested it and maybe it isn't so stable because the kernel itself can manage the cpu-settings much faster then a shell-script

2.) ... but I think we can recover this function and make it optional via ExTweaks :)
[Galaxy S II Android Development] HyperEscape:
Hello,

I have been using the 5.51 on SGS-II running ressurection remix v.2.61

I just need to know about any real performance gains and possible problems if I update to v5.55 and turn on the Cortex Brain.

Is there any way to disable or switch off the cortex brain and "Undo" all the tweaks and changes it has done.

Please guide so I can make the switch and start using it.

Thanks.
[Galaxy S II Android Development] johnbeetee:
1. can't think of any problems if you update the kernel, it's gotten a lot better since 5.51 ; just read the changelog on opening post

Just be sure to update the superuser in extweaks by removing root/root again under misc tab (as mentioned in changelog)

2. cortexbrain can be enabled or disabled in extweaks ; these are runtime optimizations, so if it doesn't work out for you, just disable in extweaks, and reboot, and they are all gone.
[Galaxy S II Android Development] iamnotkurtcobain:
Do I have to use extweaks? Can I just adjust some basic stuff like scheduler, gpu clocks with another app. Don't want to change all this stuff.

Edit: and btw is battery life/performance better than cm10 stock kernel?

Gesendet von meinem GT-I9100 mit Tapatalk 2
[Galaxy S II Android Development] It_ler:
Just to change min./max. CPU freq., scheduler/governor and etc. you don't need to use ExTweaks - can be done with Voltage Control for example.

But other settings can only be changed with ExTweaks (or scripts).
[Galaxy S II Android Development] iamnotkurtcobain:
So if i install extweaks and change stuff and then deinstall it the changes are saved or lost?

Gesendet von meinem GT-I9100 mit Tapatalk 2
[Galaxy S II Android Development] It_ler:
AFAIK, ExTweaks saves its settings in a script (file).

And this script should stay even if you uninstall ExTweaks.

But I am not absolutely sure about that ... just guessing.
[Galaxy S II Android Development] iamnotkurtcobain:
Thanks. Is Hype Gov better than pegasusq? Scheduler?

Gesendet von meinem GT-I9100 mit Tapatalk 2
[Galaxy S II Android Development] johnbeetee:
...that's correct ; the changed profiles remain saved and active, until you clear them yourself or flash new kernel and they are cleared by the kernel because of new options/or format

Just out of curiosity @iamnotkurtcobain : why uninstall extweaks after settings? It does nothing, unless you use it, and it takes up very little space...

---------- Post added at 11:58 AM ---------- Previous post was at 11:56 AM ----------

Personally I think so......but that's just my opinion
[Galaxy S II Android Development] iamnotkurtcobain:
Thanks! And what scheduler do you prefer?

Gesendet von meinem GT-I9100 mit Tapatalk 2
[Galaxy S II Android Development] johnbeetee:
the io scheduler only has impact on file/data transfers ; the most simplest is noop and is ok and uses the least resources ; i use the standard sio.

If you don't do a lot file transfering/copying/downloading data/watching movies while you're downloading/ or funny things like that, any one will do the job
[Galaxy S II Android Development] stevtec86:
Hi Dori, I state that I mount SammyRom BluRom V3 ics 4.0.3 ... and I still wanted to try the 5:55 .... I also read the changelog of 5.55 and I lettio that this version could not even start on some roms 4.0.3. but .. I started .... With this version, I noticed 2 bugs and I just wanted to know if you had seen the normal version of the 4.0.3 rom or comiunque there had to be: first bug: if I go to Settings ==> Dispaly ==> Lock screen and selecting perhaps by mistake, two photos, the two selected photos disappear and doing the procedure, after telling me that there is no evidence, while checking the photos on file there. second bug: often the music player that I have (what dell'S3) is not even here the song, but checking the songs are on file. this happens with 5.55 ... but if I put, as I did now, okay ... 5.54 is normal or not? Again, when I have the V3 BluRom ICS 4.0.3 and the bug I 5.55, with 5:54 no ...

Thanks x your attention I apologize for the bad English x, and I hope I was clear!
[Galaxy S II Android Development] iamnotkurtcobain:
My default scheduler is also sio. So thanks

Just a friendly reminder:

Push the "Thanks" button instead of saying thanks in a post.

In xda or Tapatalk app, just long press the post you want to thank, then scroll a little bit to the right and select "Thanks" (or "Danke").

This will lead to less "unneeded" posts and better "Thanksmeter" values of helping users.
[Galaxy S II Android Development] voku1987:
... but I prefer to use "ExTweaks" because it dosn't start at boot and so it dosn't drain battery :) this is also the reason why I don't use "Task Killer"-App, "Battery Saving"-App, ... etc.
[Galaxy S II Android Development] It_ler:
I also prefer ExTweaks when running a compatible kernel, but the user to whom I answered doesn't want to use ExTweaks ... I don't know why.

If you do decide to change or try another modem (radio firmware). it may be wise to change the RIL library file too (radio interface layer).

A mismatch, doesn't nescesarily mean problems, as these mismatches are very common due to roms having a specific RIL lib, and users having a different modem. But it won't hurt to check.

You can download GetRIL app from the market and have it checked and fixed if needed. (Thanx to Tungstwenty for this tip ! ).

I got a similar problem to some, on lpg rom after using latest siyah 4.0 kernel, and flashing your kernel the Rom would not boot. Going back to siyah resolves the problem, maybe Siyah leaves something behind. Tried reseting profiles etc
[Galaxy S II Android Development] johnbeetee:
If I'm not mistaken, all extweaks profiles now have cortexbrain on by default. This means it will auto-switch from awake-mode to sleep-mode.

This sets the values for the cpu freq. (upper/lower limits) according to the values you choose in extweaks, and this will override the values you change with another app. So you'll have to:

a. use extweaks and disable cortexbrain or

b. use extweaks and disable cortexbrain, disable cpu tweaks, and enable cortexbrain again or

c. use extweaks and change your desired values there
