Processor scaling, strange behaviour - Sony Ericsson XPERIA X10 Mini

this is what happens on my x10 mini... the cpu seems not to scale well and maybe this could be the reason why we have so poor battery performance expecially while in standby
using adb mask controller http://forum.xda-developers.com/showthread.php?t=868423
something I can do?

Help me to overclock x10

Hello..anyone can teach me how to overclock xperia x10
Bootloader is not unlocked. It's impossible at the moment.

First, you crack the bootloader.
When you've done that, I'm guessing you allready figured out how to OC the CPU

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

On SetCPU there is Set on boot- to be checked or not?

it should be checked
OC can damage yo device. Id say its better to hv a lil slower device than a dead device

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".

Proper SetCPU profiles for high clocking on mini pro.

If you find any problems correct me.
I usually have my mini pro clocked at 825Mhz.. but i found that it can lead to stability issue's when the battery gets low.
Here's how i counter act that.
I create a cpu profile that checks the battery status
If it gets bellow 15% i drop my max clock from 825 to 600mhz.
This gives me lean stability at low battery conditions.
DAMMIT.. sorry i meant to post this in GENERAL, sorry.

[Q] Wrong cpu core handling?

As I noticed, when I change governor in setcpu to anything except hotplug the system information states that: We have only one core! WHAT? WHY?
I know, it can be a delay between measures, and some of the governors are reducing freq and so on. I know how could that work. Hot plug can disable the second core, and when i measured MFLOPS with linpack (gov: performance) that clearly shows same score with multithread maybe a bit less than single thread. I had only one active core... Something not clear sometimes. I repeated the tests with every governor and I don't have any idea whats wrong with them, sometimes the second is just out of usage, sometimes working well.
Sorry if that not enough clear.
Anybody else can check that?
I just benchmarked with linpack and also get about the same scores for multi and single-Thread performance. That is indeed very strange. I tried changing back to hotplug but still got the same score for multi and single-Thread performance.
edit:
I removed "set on boot" in SetCPU and rebooted, THAN i got dual core performance again with a score of about 55 MFLOPS. I replaced SetCPU with no-frills CPU control, changing back to hotplug allways seem to work there instantly. Hotplug makes the device freeze randomly and anything else makes it half as fast. I'm beginning to dislike my Archos Tab...

Is my Z5c throttling?

Hello guys,
I bought this phone about two days after release and was pretty happy with it. It felt like the Snapdragon 810 didn't overheat at all and the performance was far better than on my "old" Z3.
Reason enough for me to try PPSSPP and emulate some good old games. For example MHP3rd ran at 100% speed in every area in-game with no frameskip activated.
But after some time (I'd say 20-30 mins) the cpu throttled a lot. The game speed was only at 50% even though the device didn't feel THAT hot (I've seen/felt hotter ones).
I tried the same thing again with the app "CPU Temp", and it seems like the CPU temperature never exceeded about 58°C. I'm not sure about smartphone CPUs but as far as I know, most chips can take up to 80-90°C until they start throttling. My Z5c runs at 52-58°C perfectly fine, but suddenly starts throttling for some reason.
Is it the CPU governor that tries to save battery life? I'd probably need to root the phone to "fix" this, but there are no roots available yet.
Or is it something else? Is the max. cpu temperature set too low? Could it be the S810 has no real temperature sensor and CPU Temp shows me something completely different?
Thanks in advance!
Greets,
Uftherr
I think that Sony it's throttling the CPU more to be below 58°C than to save battery life.
Try with the latest firmware (released today at PC Companion) it seems to be a little more snappier (maybe its a placebo).
I don't know why because the kernel is from the same date.
I consider that they should let the phone gain 65°C to increase the performance (at heat cost).

CPU problem

There's something odd with Snapdragon 625 on RN4 (according to me).
I have noticed that the maximum clock is half of the times coming down to 1.6GHz or less instead of 2.0GHz, especially when charging when the phone is warm (but temperature isn't high enough to trigger down clocking-- around 30-40 degree Celsius).
This also happens when the phone is not charging and I am doing some task like using apps or playing games when the phone's hardly heating up (afterall, SD 625 is known for its no heating issues).
It looks like whenever I am doing some task that doesn't involve much processing, the max clock comes down (but when I am performing some CPU intensive task such as installing an app, the max clock stays at 2GHz).
I am using interactive governor. PLEASE NOTE THAT I AM TALKING ABOUT THE MAXIMUM CPU CLOCK WHICH IS AFFECTED IN MY CASE. Using Kernel Adiutor to reset max freq. to 2GHz hardly works. It seems like the system ignores my clock settings. Even if i set the governor to performance, the max clock still keeps coming down and going up.
What's the deal with this processor?
Also, all the 8 cores are ALWAYS ON. There's no option for CPU hotplug in Kernel Adiutor.
Please someone shed some light over this.
CPU is thermal throttling not only when CPU is hot, but also when battery is hot. Also it is using a frequency which it needs, if it's using 1.6ghz it means it doesnt need more for whatever you have been doing.

It also happens when the phone is not warm/hot.
Please note that I'm not talking about the current frequency that is being used, I AM TALKING ABOUT THE MAX FREQ that is pulled down and up when I am working (even when just simply using the phone for little tasks which doesn't really heat the phone up).
While using any governor, the max freq should stick to what it is set to and the current freq varies. But here, the max freq is varying along with the current freq. Is this some feature or what?
If this is actually due to heating, is the management so bad that even 35-40 degree celsius makes the CPU throttle? Generally throttling happens at much higher temperatures.
This is 14nm SoC, it has much lower temperatures but also much lower max temp. (throttling start on lower temps)
You can't heat up this CPU to 60C or more like Snapdragon 8xx for example, because it will shut down.

LOL means I can't make good use of the 2GHz 8 core CPU for long because it'll heat up and simply throttle down. That's too stupid to have a powerful processor.
i am having heating issue. I found no thread discussing.. I am in Miui9 global beta version. Rooted withMagisk using redwolf twrp. My top part of screen heats in normal usage for 5 minute in wifi/data.I have checked the cpu temp( maximum 42) and battery tem( 36 to 38)..But the screen become hot..any work around? Is it a software or hardware issue? how to resolve it
