hi. i'd like to monitorize cpu temp using cooltool, but i don't know where the thermal file is situated, anyone ?

I am using an hd2, and i have noticed something that may be causing a lot of battery drain, that is consistent among every build that I have used. When I use setcpu, and give it root access, and whether i select auto detect or manually put in nexus one/snap dragon, it does not listen to the cpu cap that i put. i will exit the app, and go back to it, and the cpu clock speed with almost always exceed the cpu cap that i set, and many times, it will be running at the full 998 mhz. why is this, and how can i fix it?
I uninstalled SetCPU the other day as a little experiment. It makes f-all difference to me. In fact it makes things worse.
no longer needed with the latest kernels

This problem seems to relate to a kernel feature called perflock .. disabling this in-kernel allows the cpu cap in setcpu to be adhered to .. Unfortunately this is done at compile time and has no userland interface to use. I dont think its relating to all the battery drain you see but for sure if you limit cpu speeds with profiles like screen off it will have an effect.
try updateing super user libraries.

Whats that then ?
how would i go about updating the su libraries? does anybody have an actual fix to this, because i would think my battery would be a lot better if the set cpu app was actaully working. and no, the latest kernels dont seem to be doing their job, because they all burn through juice like theres no tomorrow.
u have 2.04 installed ? it fc'd for me , now im using 2.02 no problems , try that

You don't update the su libraries .. su is either a static file or a link to busybox .. i cba looking right now .. probably a binary compiled statically ..
To have your issue resolved have a word with your friendly neighborhood kernel builder and ask him to disable perflock .. Its not needed for normal operation.
I'm having the same problem. Does anyone know how to get setcpu to work?! I have an HD2 running darkstone Froyo.
Hi guys, I'm a newbie :victory: and I do have some questions.
First of all, is it possible to change GPU frequency according to the load? Or is it locked with CPU frequency?
Second, I want to change my vdd_list. What step voltage should I use?
Also right now I tweak my governer by using echo values in init.d. Instead of using init.d scripts, can I just flash a zip to integrate the changes in the kernel? If so, how can I do that?
Thanks all.
Theoretically it's possible to change GPU freq, but the possible changes are very limited.
If your governor reads some sort of config file on load - you can modify that config file. Otherwise to make changes to kernel defaults you need to recompile it.

Could you show me how? I would like to change my GPU freq in order to test out during the normal use, my phone's performance is more depending on GPU or CPU.
Thanks.
Evenin all.
I have just flashed the motley kernel to my nexus 7 and have been able to change the cpu speed to 1.6ghz but am comming up blanks when figuring out how to change the gpu speed? (i have searched everywhere and cannot see how people do it?)
the only tip i saw was to explore the root of my device and go to sys/devices/system/cpu/cpu0/cpufreq and change a value in a gpu_oc file however there is no cuch file anywhere only cpu files.
anyone have a clue as to how i can change my gpu frequency?
thanks all.

big question.. has motley enabled the ability to change/edit gpu speed. without him enabling it, theres no way to change it. not all developers enable changing gpu speeds in their kernels.
You can run Trinity kernel and use trickster mod (app) to tweak your CPU and GPU to whatever you want.
Hi! I seen post like this before but I wanted to know why my phone (ALE-L21) have only 4 cores? I tried to modify CORE File in system , but I Failed! Can anyone tell me is there solution? Flashable Zip file? .img file?
In rest or low CPU usage 4 cores are offline for battery save
1. Use System Panel 2 to check core usage(it will show all cores doing somethin). Not 100% sure does it show correct info, but it feels like it does. (No idea how to test if info is correct)
2. Go to system/app/HwPowerGenieEngine3/ and rename HwPowerGenieEngine3.apk to something like HwPowerGenieEngine3.apko --> then reboot.
These step seem to have some effect for all cores to work. Also I think ESAL kernel has slight increase for amount of cores used.

I used CPU burner to see changes but only on SystemMotitor2 i saw changes! On other apps nothing changed
Kennel Auditor maybe

In AnTuTu benchmark i see this all cores have % but they are sleep! In Kernel Auditor, they are offline

Yeah, I think you can enable them in Kernel Auditor though

They Automatically Goes offline! Maybe hotplug switch's them off?
I think they work just when they are needed, such when streaming videos or doing something heavy
The manufacturer won't put 8 cores if they will disable 4 of them permanently
Maybe we can't observe them because the are controlled in behavior lower than ART
i think they are just fake..
I need custom Kernel, Then i will get them to work!

Bro, even if i have 200 threads via CPU burner, they don't work! I have 100% Load but they stay offline
In Ex Kernel Manager theres a page that has several temp sensors. I found this online:
https://source.codeaurora.org/quic/...s/qcom/msm8996.dtsi?h=LA.HB.1.3.1_rb1.8#n2496
But all i can tell is that sensor 15 is the gpu, anyone know which is the cpu?
4,6,9, and 11. Choosing any one is fine.
cool thx ;p
