What CPU frequency changer app do you recommend?

[Addyhash]

Hi follow forumians... i have the s89-h with 108k4, i previously was running 104k4, and i find since flashing to 108, the cpu temp gets a little high during movie streaming ( 80 degrees! ) and picture gets a little stuttery, so i tried to install 'set cpu' to underclock slightly, ( i have the paid version over clocking my HTC Inc S ) but found the cpu frequencies don't stick, i can't see it being due to the kernal or else the frequencies would be greyed out and not selectable...

any ideas, or has anyone had better results from other cpu clocker apps...

Cheers

Addy

edit... might be answering my own question... looks like that's the norm on stock f/w's but found this topic...:

http://www.freaktab.com/showthread.php?16882-Kernel-108k4-Cpu-Control-s82-s89-Adjust-Cpu-to-1992mhz-S802-devices

now that ive had the unit a couple of months and HDMi connector is still hanging on, i might try some cooling mods first ( im sure a gaping hole in the lid with a pc fan will void the warrantly lol! )

Did you try "No-frills CPU Control"?

https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU

You also can "play" with this by ADB, terminal emulator or your own apk from:

/sys/devices/system/cpu/cpu0/cpufreq

init.d

I use a script. Below is what i use for my mk808b. You will have to adjust to suit your needs and speeds.

#!/system/bin/sh
sleep 15s
echo "interactive" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo "interactive" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
echo "1608000" > /sys/devices/system/cpu/cpufreq/interactive/hispeed_freq

# Available frequencies for hispeed_freq are 252000, 504000, 816000, 1008000, 120000, 1272000, 1416000, 1512000, 1608000
# Make a cwm backup before pushing. If you have issues try IPad charger and good usb cable or make a usb cable.
# You do not need to run a program like setcpu with this script in use.

Why that

sleep 15s

I was playing a little with bash scripting some days ago...

[Javimetal]

BTW, do you have complete info about bash script for Android?

I have seen people who must to use:

#!/system/bin/sh
ADB Shell echo .........

Also some ones who need to change the double quote " to simple ' or even this one ´

I think he only use it to be sure that other processes up / boot up finished...

I don't know any need of this at the device (./system/bin/adb)...
Maybe to open/start a separate shell ???

"complete info about bash script for Android?" I don't think something like this exists and shell scripting at Android isn't same powerful as at PC or "full" Linux at the box...
One of the important toys is the busybox also for scripting and often commands not as powerful as at PC or "full" Linux at the box...

it wouldn't work without it. i think the script runs earlier then when the system sets it and the system puts to stock.

This is straight shell i believe. But you can get bash compiled for android. Just google it and it will pop up in a forum.

off topic

Here is another one I adapted from another script. Runs once and loads all apk's on external sdcard in apk folder. After flag is set it bypasses. Gonna include in any new roms.

#!/system/bin/sh
sleep 30s
FLAG="/data/system/firstboot.log"
if [ ! -f $FLAG ]; then
    mount -o remount,rw rootfs /
    mount -o remount,rw /system
    cd /mnt/external_sd/apk
    for file in $(ls *.apk)
    do
        if [ ! -f "/data/app/$file" ]; then
            echo $file
            busybox cp /mnt/external_sd/apk/$file /data/app/
            chown system:system /data/app/$file
            chmod 644 /data/app/$file
        fi
   touch $FLAG
   done
else
   echo "Do nothing"
fi

Is it not possible to know when the system finished boot? Like if we want launch an app at startup, if we wait 15 seconds the launcher will be showed first.

I guess we can launch an app by using something like:

am start com.android.settings

but we can't get the moment when everything is loaded.

I can do it from an app by listening the BOOT_COMPLETED


Thanks for sharing about boot scripting, few info in the web

[no_spam_for_me]

This can help

while [ ""`getprop dev.bootcomplete` != "1" ] ; do sleep 1; done

but there also exists situations where it isn't finished (but not often)...

[CarlosCL]

Really good!

I think I will learn a lot here.

I'd like to make my own small CPU control APP and if possible include it in the "Settings", but I see it is a little difficult to compile the Settings.apk from any RK3188 SDK. Or at least can not from elipse...

[CarlosCL]

Also another thing about Hard. control. I can set the CPU speed, governor and so on but, is there any place to do same with RAM? I have been looking for some days and did not find any way.

I have been testing a good ROM but the stick becomes really hot, I found (by an IR thermometer) the problem comes from the RAM, it's really hot. After change CPU speed to low I can control this problem a little, but, is it not better to decrease the RAM speed? Also, when the actual RAM speed can be seen?

Thanks!!!

I don't think so, normally it's compiled inside the kernel because it's controlled, if I'm not wrong, via Volt...
So you need an uncompressed kernel and you have to know where to patch (binary)...

Maybe you are able to read the 'DVFS TREE' at dmesg:
1. 'adb shell cat /sys/dvfs/dvfs_tree'
2. 'adb shell dmesg > dmesg.txt'

I use an app from xda called Performance Control
Its originally from Aokp ROMs, but is open source so
could Be used in ROMs here I suppose
It works really well and shows the cores active or not active

But I found the reason why the settings don't stick
Its the kernel, a file init.amlogic.board.rc
Has a line
Scaling_dflt_freq 1608

/sys/devices/system/cpu/cpu1/cpufreq/scaling_dflt_freq 1608

This needs to be commented out or removed or set to 0
This then allows the CPU level to be changed and
stick

I'm trying something like this:

#!/system/bin/sh
sleep 15s
am start com.android.settings

I tried to save as "script" and also as "script.sh" (which one is correct?)

It does not work. When I execute by #sh script it shows an error, it said "15s" is wrong. Also can not open the activity.

I also tried to create a directory:

#!/system/bin/sh
mount -o remount,rw rootfs /
mount -o remount, rw /system
busybox mkdir /etc/init.d/hello

Also does not work.

Anyway, the most important I want to do is launch an activity (or the app). When I write

#am start com.android.settings

I can see Settings APK opens without any problem, same for another apps if I use their main activity. But I can not do it by a bash script.
