[KERNEL] Kernel (deprimed_test) - Break It If You Can

[haproot]

Hmm how about

Su
Cd /system/etc/init.d
Sysrw
chmod 0755 20overclock
Rm 20overclock
Sysro
Primed

I'm new to this kernel and have it running at 900MHz with CM7 on my Droid. Can someone tell me how to bump this up to 1000+MHz? Looks like the options top out at 900. I tried reading through all 100+ pages of this thread, but didn't make it very far.

EDIT: I used the Milestone Overclock app to bump it to 1200. Reverts back to 900 though on a reboot, even if I tell it to restore on reboot. Am I missing something?

Right after "chmod 0755 20overclock" it fires, "Unable to chmod 20overclock: No such file or directory"

Then I figured it was gone, but input "primed," and got the same thing as before. :\

Wow that is weird, I'm not totally sure what is going on. Do you have root explorer? Can you browse to /system/etc/init.d? Maybe delete the 20overclock file that way and try the primed command again..

You have to edit your 20overclock file with your verified settings and it will become available in the cyanogen settings under performance>cpu settings, you can set on boot there. Here is my file for 1000mhz. You may want to try a higher vsel value than 59, maybe try 60 or 61.

Edit: DER! use a vsel of 74 or higher for 1200mhz..

Thanks for all of your help. Sorry its persistant.

Get this:

20overclock isn't even there in /system/etc/init.d
Nothing to delete.... As a matter of fact, I did a search using Root Explorer and it found no "20overclock" file.

I do have cpufreq, if that has anything to do with it?

 

[haproot]

Do you have a 99overclock file in /system/bin?
Dont know if cpu freq would have any effect.

CM 7.0.2 and camcorder problem

Gave the deprimed kernel a test run. My main goal is battery life so went right for the overclock script to get ulv. After enabled anytime I take a camcorder video it seems to hang when i tell my phone to stop recording the video(guess when it's trying to save it or something). I get the force close message for camcorder.

Does this kernel offer battery savings over the stock CM 7.0.2 without the overclock ulv stuff? Any suggestions?

Is CM7 just too much OS for the Droid to give the optimal battery life?

From zeppelinrox's work (XDA link) try this.

nothing in there about compcache's interaction with OOM.

It has nothing to do with compcache. It has to do with keeping the application you want from dying from an OOM situation....this is what you want.

Zram uses resources to move the data to and from the compressed ram block device (this uses CPU resources as well), once a certain level is reached compcache can not restart because android can't push the large amount of compressed memory back into normal system memory. You can't use compcache in the way you want, it's not fine grained like that. You must force the desired OOM value to the application you want to stay in memory or use real SD Card swap and try to fine tune the swappiness (SD swap has the same issue with stopping or restarting..will bring the system down).

ok so I set content provider to 25MB and empty application to 30MB. 32/40 was a wee agressive I thought but I may go back to that. With it set like this I can keep my compcache at 30 swappiness no problem, the CPU can move memory back from compcache to RAM and send it to flash no problem. Thanks for the help. Love this fone.

 

[rancur3p1c]

hey prime, still wondering if low compcache numbers are normal? im only at 592, when before after booting id be in the thousands

create a file in /etc/init.d named 99compcache
in it write the line
echo 30 > /proc/sys/vm/swappiness
save and exit,
this will set swappiness to 30.

then get auto memory manager from the market,
click the "mild" button and hit apply. That should set you up good.

 

[rancur3p1c]

prime, what do you think about using both compcache and swapper2 at the same time? My compcache is filling up several times a day lately forcing me to reboot.

I know I'm not prime but I do have to say that swapper2 has always made my fone...funky...eventually...like after 24 hours when the swap gets filled...it just starts acting strange. Perhaps I had too large of a swap configured.

 

[rancur3p1c]

prime not sure how you keep up with these posts and keep supporting like crazy but good work, definitely love the kernel, haven't run anything that was snappier. It feels at least 20% faster clock for clock I'd say. Very well optimized.

 

[dberthia]

Thanks. I noticed I had a number of errors when I ran the "primed" script:

insmod: init_module 'overclock.ko' failed (operation not permitted)

and a number of "permission denied" errors trying to write to proc/overclock.

Any advice for getting around these?

Yes sir, it's just "overclock" in /system/bin
