I have a problem with my m4 Aqua. All my cpu cores Are active when screen is on. I am using on demand cpu governor. Even with the other cpu governors the problem is still there. I have this problem with 3 different stock firmwares.
Is there anyone Who dont have this problem?
I think that's the way SD 615 works because I have the same problem
Dude... That's exactly what should be happening lol. It's not a problem - it's normal in every phone. You can manually deactivate some of them if it pleases you.

Thanks for your answers but i disagree. On my Z1 Compact, it only activates the other cores when i touch the screen, or when it needs the extra juice. Not only because it's on. This results in a huge battery waste wich i don't have on my z1c.

Not true, most of the processors have just only one core activated when you are doing nothing and it turns on more cores when it needs them. This is the first processor I've seen that almost has all the cores turned on all the time.
i think sony disabled for some reason mpdecision hotplug
Ahh my bad. Thanks for correcting guys! How did you guys check for it though?

Is it possible to change that without making a custom kernel?
Sadly, no, i tried to turn mpdecision on using terminal emulator and nothing happened, maybe sony ripped this function at all in kernel
But if you need to save battery and still have a good system response i recommend to set the 4 big cores to powersave governor and let the small cores in interactive, you can set like this using kernel adiutor (is totally compatible with big.LITTLE arch and can manage individually the smalls and big cores)

Ok so im rooted and overclocked and was using setcpu then decided i wanna try something different so i tried system tuner! When i checked the cpu it said that one of the processors are off line! Then i pressed the info button and sure enough it says only reading one! So i went through the settings and found force both cores online!
Since then i have no lag and virtually no checkerboarding on the web! Anyway i was just wondering if im the only one who noticed this and maybe it could help those who say that they are still getting lag on they're roms using dag's kernel!
Also i hope devs will notice this thread since i can't post there yet and take advantage of this how ever they can!
Now don't quote me on this but most likely the second core only turns on for processor intensive activities such as high graphics games or multiple programs running at once. I do find it hard to believe that it would be totally disabled. Most likely this is done to conserve battery.

Nope i checked that i had 10 apps open two were games (dead space and gta III) One cpu online even on performance! I see 50 views i hope others chime in and let us know what you are thinking
Btw they Did this i heard to the galaxy nexus with the tiomap 1.2 so we'll see what others find

Okay if this really is the case I could also see at&t disabling the second core totally to save battery because of lte but i guess it will take a dev that has more experience with how qualcomm's multicore cpus work in android. report back with differences in battery life like how much faster does it drain now that both cores are forced on.
if you want both cores on click on boot settings and enable force all cpus online. that heats up your phone and eats more battery though+I do not see any benefits doing that.

Tomorrow ill post some pics of battery life usage!
And my phone doesn't get any hotter than normal not even while using my navi! Mostly it just gives no lag and better rendering in the browser/maps/etc!!
I was under the impression that Gingerbread didn't fully utilize multiple cores. Need HC or ICS...

Same, but having a better processor helps. Like exynos. I bet once we update to ics if it ever happens, the differences will be only minor between processors, as it runs so nice.
Got system tuner pro, and it shows speed bars on both cpus running? I didn't change a thing?

Really? I switched Roms twice today and had to reset that each time! Cpu.0 online Cpu.1 offline! Like i said am i the only one? Lets hear from more people and let us know of any lag or rendering changes after turning on both cpu's! Battery too, i'll post mine tomorrow.
I thought I'd play and I have CPU0 running and CPU1 running.

Not entirely true.. the Galaxy Nexus has a kernel governor that turns one core off when the SCREEN IS OFF, but not when the phone is being used. Multiple kernel creators have since implemented this into their kernels. It is called "hot plugging" and it just turns CPU 1 offline when the screen is off and turns it back on when the screen is on

Just checked mine, rooted and OC with DaG's 0.1 version (first version). When I looked, it said the second CPU was offline. Changed it to online, we'll see how that impacts battery life.
How much of an advantage is smartassv2 anyway?
I just tried this with system tuner and both cpus were working but wone was of and on and zero was always on.
I am running stock rooted. If you just sit yhere and watch it you will see tje sevond core fires and shuts down alot.

Same for me (CPU 0 on, CPU1 off, most times) and I'll say I have noticed no real changes in functionality (speed, rendering, etc) or battery life...
I guess jury is still out or is this a YMMV kind of thing?
I installed system runner and watched the cpus. One was on and the other kicked in periodically
Mine said it was offline as well. Forced it on and am not noticing any difference in speed or temp.
Ill leave it like this to test it further.

As far as I know yes you must have super user permission to alter such system activities
I don't know why everyone is in such a rush to force the second core online, it turns on and off when it needs to.
So I installed system tuner from playstore and I'm looking at both cpu's and I noticed CPU 0 is running 100% of the time and CPU 1 is offline 99% of the time? I have this app on my galaxy nexus and CPU 0 and 1 would be online 100% of the time, so any of u guys wanna download that app and post ur results?? Or dose someone out there that nos more about the chips in this phone care to " school " me? ///my phone is rooted

It's the way that all dual core phones work to save battery. When using the phone heavily, both should kick on. While not doing anything or not processor heavy, just one core would run.

Correct.
CPU1 is rarely ever used. This is to conserve battery. It gets turned on/used only when there is a demand for extra processing power.
But some custom ROM/kernel combo's will change it so that CPU1 is used 100% of the time. I'd guess you had a custom kernel on your Nexus?

Thank u guys, This is what I figured, but I've never had stock rom and kernel on any of my other dual core phones this is longest I've ever had stock rom and kernel (4 days ; p) and had no idea CPU 1 is never really used cause yes most kernels take advantage of both, I turned on CPU 1 with the app but I don't think its working right, phone seems faster but I need run some tests ....thanks agn
alright. ive been playing around and cant find some good governors for what i want.
for hardcore gaming, what governor have you found that works the best
for best batter saving, but still be able to watch videos, surf web, email and just general navigating without it being too slow.
which governors do you guys use for both of those? thanks

Use the smartassV2 governor. It regulates the CPU frequency according to load (sorta like ondemand except it works better).

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Alright now my problem is that I set my CPU to 192mhz lowest and 1.24 max. And that's for normal use. I'm running smart ass2 Nd it's not licking my CPU at max anymore, but it keeps.moving the max to 1.51ghz.
any ideas on how to fix tht?

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.
Hello all
I have a bit of a small problem. I like to run my phone using the Performance Governor but after a while it goes to 1Ghz on all 4 cores despite me running it at 1.8Ghz. Setting it back seems to correct the issue but in time it goes down again.
I believe it is getting a bit warm and thus it hits a limit and the system auto slows to 1Ghz.
Can anyone confirm this behaviour? It never happened to me before but I have had a few kernel updates and updates to the Omega ROM that could be the cause but I am not sure. Is there a setting where I can tell my phone what temps to throttle at?
Also, I assume all this is down to the Kernel and not the ROMs?
Would like some imput regards where to start my search to return my phone to its previous state as a pocket heater.
Many Thanks

Don't use it. Pegasusq is the only one really working for multi-core CPU's with hotplugging and so on.

1.8Ghz is not healthy for the CPU in the long run and will cause overheating which is exactly what you are currently seeing.
Especially since you keep the phone on 100% CPU power all the time (performance governor) which should drain battery like hell as a side effect.

This is down to your settings. Neither rom nor kernel.
- Don't overclock (much)
-Use a good kernel such as Siyah
-Undervolt if the phone remains stable
-Use pegasusq Governor

Hi buddy and thanks for your response.
I am not sure about what you said regarding it working correctly, it gets the best results for any benchmark compared to others so I would be interested in more detail about the specifics of how its not working correctly as I have never been told that. It would be appreciated.
I dont mind the battery drain although I do heed your warning about about longevity of the CPU.
I have been using Siyah Kernel for some time now and I find undervolting a little unstable, for now I am forced to use pegasusq.
Can you or anyone else answer the original question as I still wish to pursue this to a resolve other than not using it.
Many thanks for your time and efforts non the less!

it´s samsung´s based roms related: when the battery temp hits 41C the cpu will throttle. Nothing related with de cpu temp (can be at 80C before throttles).
try CM10.1 and you´ll see what im talking about.
We need a solution for this throttling with samsung based roms
Hi!
I was reading that Tegra 2 uses some sort of integrated governor, but for me i don't think it's working really well because my phone jumps almost straight to 1GHz.
While using SetCpu i realized that the governor option doesn't contain anything at all, is this normal ?
