CPUfreq interactive governor

**nadlabak** · 07-26-2010, 06:46 AM

If you want to try the new interactive governor, (readme) on Milestone, you can find the adapted version for the Milestone 2.6.29 kernel (binary + source) here:

i've tested this, and changes aren't noticable?

anyway i can see something physically change or? is it purely cpu related, so if im on 1000Mhz i dont notice much?

works, thanks!

for anybody who wants to try: if u use overclocking and setcpu u must change "Scaling" in SetCPU to "interactive" because otherwise SetCPU overwrites the "echo interactive > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"

BTW: insmod can be included in "71_overclocking.sh", works great

dext3r: the governor controls the switching between available CPU frequencies. The goal of a governor is to provide an optimal balance between the available CPU power and the battery life by clocking the CPU at higher frequencies only when it is actually needed. Usually, when it detects higher CPU load, it switches to higher frequency, when the CPU load drops, it switches to lower freq. Different governors use different switching strategies and different load sensing. The new interactive governor reacts faster than the default ondemand, making the responsiveness of the phone to UI actions even quicker. You can easily switch and compare the governors by SetCPU. The reactions of the conservative governor are the slowest, ondemand is faster, interactive is the fastest.

hmmm ... i've made an extra .sh in the the folder and i can't select it in setCPU. what did i do wrong?

can u post your script?

**nadlabak** · 07-27-2010, 05:43 AM

What's in your script?
Has your script the correct permissions (755)?
Have you copied the cpufreq_interactive.ko to /system/lib/modules?
Have you set the correct permissions for it?

Code:

chmod 644 /system/lib/modules/cpufreq_interactive.ko

Have you set the correct owner for it?
under recovery:

Code:

chown 0.0 /system/lib/modules/cpufreq_interactive.ko

or under running system:

Code:

chown root.root /system/lib/modules/cpufreq_interactive.ko

hi nadlabak, sorry for early post. perhaps i should have had a deeper look at the things missing

it's running now fine. owner needs not to be changed

i simply forgot to copy the kernel module to the correct place. now, i can select it in SetCPU. I will let it run a few days and then i'll report back, if it's working fine!

@dexter: maybe, you may teach me how to insmod this module with the froyo "frankenstein" port

this will be fine. where do i have to add the lines? in mot_boot_mode at /system/ or in the root directory (as i know, these files are overwritten by ramdisk).

the best place right now is in the "ramdisk.tar",
add the command into the "overclock" script, and its loaded at startup.
you might need to consider having the module in the ramdisk.tar too, as /system is pretty full :-)

perhaps you might consider to call a "modding.sh" script from a point in the ramdisk where are modifications may start? something like:

/system/bin/modding.sh

And check before, if this file exists? From there, everyone may start with modding (such as adding the new governor).

I'm not familar with ramdisk. Extracting it and repackage it with WinRaR ist not possible i think?
