Second core script - Motorola Droid X2

Ok so I was reading that bootloader effort thread and _base2 had mentioned overclocking his RAZR I tried to link the post and it wasn't working well on the app...kept foreclosing so anyways...I made a script that activates the second core...the way I verified this is looking in system tuner with it running and with out...also without it shows as an ARM processor in antutu benchmark and a dual core with it. with the limits of our kernel its not going to let us multithread obviously if I am not mistaken
Razz1 was the original poster if this on rootzwiki for the razr
If you choose to make changes or try it and something bad happens its up to you and I can't be held responsible
Ok so to further clarify what im trying to say with this is....prior to using this the second core was not visible using cat proc /cpuinfo nor was it available to java according to quadrant or antutu...after it is available and shows in the cat
This is what I used when I built my script
chmod 666 /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu1/online
chmod 444 /sys/devices/system/cpu/cpu1/online

Ok so from what I could find and tell the second core was not being utilized on our phone correct? So what I was trying to do and from what I can see is enabling the second core...
And I am having trouble uploading it will paste what I made into a script...
chmod 666 /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu1/online
chmod 444 /sys/devices/system/cpu/cpu1/online

okay so what youre saying is that this script should use the other core efficiently, right?

Just looking for feedback if what I am seeing is correct because prior to doing this the second core was not visible at all and from what I see in system monitor its running at least

What I am saying is that this is the stock out put from cat /proc/cpuinfo before

I can't make any guarantee that it will be efficient lol....but all im trying to say is that it would appear that its working
Hopefully I am making sense in what im trying to explain

Nice! I need to give this a try.

What I did is made a script in rom toolbox pro....under the scripter option mainly because script manager and I never got along great app just never worked well foe me....which ia probably user error...anyways if you copy the lines above and go to the scripter hit make new script paste it in and press on it select at boot and then you can just run it from there as well...you can enter it in the terminal but from my testing it that way you will lose it when you reboot so you would have to re enter it

I had some time to try this out this morning.
I made a script called cpu1 with this in it:
Code:
#!/system/bin/sh
echo "==================================="
echo "cpuinfo before:"
echo "==================================="
cat /proc/cpuinfo
echo ""
echo ""
echo "==================================="
echo "activate cpu1:"
echo "==================================="
chmod 666 /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu1/online
chmod 444 /sys/devices/system/cpu/cpu1/online
echo ""
echo ""
echo "==================================="
echo "cpuinfo after:"
echo "==================================="
cat /proc/cpuinfo
echo "==================================="
I put that script /mnt/sdcard/
Then ran it in a terminal in a terminal (i'm using eclipse and there is one built in):
Code:
$ export PATH=/data/local/bin:$PATH
$su
# cd /mnt/sdcard
# pwd
/mnt/sdcard
# sh ./cpu1 > cpu1.txt
# cat /proc/cpuinfo

I have not done much with benchmarks so I just picked Antutu and ran one before and then after.
Take a look at the screenshots attached. The after looks slightly better but it also shows that I had more ram. So I don't know if it helped. Interesting stuff though.

Thank you for the thoroughness...I was actually going to post what I found which is very similar...I don't know but to me there does seem yo be some improvement in the smoothness of my ui as well as in the speed if loading games and some smoothness as they run...I have also noticed that I have had less force closes with different apps...of course there really ia no way to quantify those observations but it is what I have been seeing....I also notice that I get 3-5 fps enabled than I do not...while not a huge difference was just something I noticed

No problem there. You got me curious and I wanted to know too. I've not really used it too much after setting cpu1 on. I think I'll add this to /etc/init.d/ so it sets automatically on reboot and see how things go for a few days.
Hey if it feels better and doesn't hurt anything. I say leave it activated.

I haven't done or used any scripts on my x2.. but I've had it for the past 7 months and have been doing a lot of flashing.. so anyway someone would be willing to put this in step by step format so that others can have dual core enables as well?
I can probably mess around with it and figure it out.. but I would rather follow a guide that ensures I'm doing it correctly.. anyway thanks for all the new dev stuff going on.. I feel brighter days for the x2.

I would like to warn everyone that performing this mod WILL severely impact your battery usage. The Android operating system is designed to operate on ONE processor and turn the second one on on-demand. IF you choose to enable both processors, your phone will run better/fast/snappier, however, this will eat your battery. Just a warning.
You can monitor what is happening with the command:
Code:
htop
Ciao!

Except it seems with this damn phone, that second processor never helps. With a phone with these specs you'd expect it to be able to run a live wallpaper smoothly or not chug to a halt when installing something while multitasking.

My data gets really slow after a while with this script on. I tried it twice in the same area, but I only got it to work normally after a reboot (the script is not on automatically).

Sounds like an unrelated issue. I fail to see how enabling a second core could disrupt cell service.
Though, I suppose anything is possible.
