Possible Overclock?

[Charle692]

Hey everyone I was exploring the system files of my tablet and I found a file called core_cap_level located in /sys/kernel/tegra_cap. This file creates the clock cap at 1.2ghz. My question is could I edit this file to raise the cap to let's say 1.7ghz? If it's possible could it be done straight from the tablet?

Current file content: "1200(1200)" which i believe means 1.2ghz

file content edited: "1700(1700)" which would mean 1.7ghz

No you need a custom kernel. if it was that easy it would have been done allready. I looked in the system too and found a bunch of files and scripts related to clock speed. Im not a dev so i dont know what they are for, but like i said if it was that easy it would have been done.
Some of the others are
/etc/cpu1.sh there are also cpu 2,3,4,5 .sh files
/sys/module/cpu_tegra and cpu_tegra3 directories have a bunch of files related to clock speed too

ive been looking into this, the kernel source i believe is available on asus website but I'm not sure if its compatible with the rom I'm using which is hydro rom, or compatible with say cm9 or aokp, theres not alot of information out there for new developers like myself. even if i did manage to download the source, modify it and compile it, how exactly would I integrate it, that I have no idea, I've always been a windows developer, when it comes to linux, things are all over the place, different builds, different hardware, different code, etc. its annoying at the same time as you can end up wasting alot of time trying to find the one thing you need to find, not alot of help out there either, if someone wants to work with me and has a little experience in dev then im sure we could solve this problem?

Ok well thanks for the replies guys and i also wan't to start up with linux/android developing but i'm also trying to learn myself. I have tried to create a kernel several times but I can never compile it correctly. Although I wasn't compiling from the source either so i wasn't able to increase the clock speeds. But it was a start.

I'd think that once you find what needs to be edited/added in one kernel weather it be cm, aokp or stock it should be almost the same for the others. Im mean arent they all based on stock and then modified? Of course you might not be able to use a cm kernel with an aokp rom, but whatever kernel you choose to start with should look very close to the others outside of some optimizations.

Oh and charle you can only compile a kernel from source, or any other program for that matter!

O sorry well i was building from the source that asus has provided us with but i meant like from the ground up or is that even possible?

Oh I misunderstood you, you said you didnt compile from the source. Yes you should be able to download the source code from asus and compile it

so whos up for an overclock project? Charles, what were you doing, describe your entire setup/processes you attempted to compile source, which source did you use, which tools, explain everything and we should try and make sense of it all, i want the tf300 up to 1.7ghz I think that would be quite stable and antutu is over 14000+

there is a kernel on prime forum so we can find out which part need to be modified, the hard part is which tools do we need, which compiler, how do we integrate this ??

maybe we can fix slow i/o for sql as well without disabling fsync

well im not completely familiar with linux this is my first attempt with it but this is not my first time developing ok well first off i was using ubuntu then I downloaded the source. I also used tools from the ndk. i first unziped everything pointed the stock-kernel to the ndk tools. Once i did that I used the make clean command which prept the kernel for compilation. Once that was done i was suppose to find the defconfig file in my kernel and run the following command in terminal "make unknown_defconig". this would configure the default configuration file but I didn't know which one to use so i pulled the config file from my tablet and i ran the command "make config" after that command i ran "make menuconfig" which opened a gui which allowed me to configure the kernel i believe? once i was finished with that i saved it and tried to compile it but i never succeeded. I know this i hard to follow, but i'm still learning myself so it's hard to explain.

I'm going to mess about myself and follow your procedure charles see if I have any luck, if any dev could shed some light or chip in, much obliged, we want more power out of this beast! the TF300 has lots of potential

 

[Charle692]

i will continue trying as well but im going to research a bit more before i start up again maybe im missing something. Let me know how it goes for you.

Keep in mind if you overclock to 1.7 you also need to up the voltage.
I think the most we can get of the 1.2 is a max of 1.5 with out a new kernel.
