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?
Sent from my ASUS Transformer Pad TF300T using XDA Premium HD app
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
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.

Hey guys lithid here again with another helper script, and how-to. As some of you may know I have recently decided to start building kernels. While I still work on roms, I found kernels to be strange, and sometimes difficult. So instead of taking that knowledge and holding it to myself, I figured I would release it here and hopefully it could open the doors for more people working on kernels.
Basically I created a script, that would do the entire build process for a kernel, it would copy the config you want from arch/arm/configs, assigned the compiler, then compile the kernel. Now after the first time I compiled this I did a copy and paste to Koush's AnyKernel updater, while that was fine and only took a min or two, I found it really annoying to do it everytime, specially when I am testing changes to the compiled kernel. So I added in a any-kernel folder to my built environment. I also added the tool-chain compiler I would be using as well into my repo.
AnyKernel folder
Cross Compiler
Now this was great. I didn't have to build anything manually, all's I needed to do was sign the zip and then push it to my phone.
Then I thought (being so lazy) why not just have this script auto-sign the zips for me and place them in my home folder? So I did. I also added in my own keys so the signature is mine! =P
Auto-Sign
Now for the fun stuff, recently there have been some roms out there that use a slightly different flashing method. Well I solved that as well. Now the script not only builds one update.zip for the compiled kernel. It creates 3 one for each rom type.
Synergy Nightly
Synergy Godmode
Universal (All other sense roms)
Click to expand...
Click to collapse
So everything is basically done. Devs would be able to implement my script into their kernel environment to build kernels for all roms that are supported here on XDA.
How to:
NOTE: You will need to get a list of applications installed and be running linux for this to work. I used Ubuntu 11.04 for all my building needs. If you want a quick list of packages you will need to install first click here there you can install corresponding packages to compile this.
Code:
git clone https://[email protected]/lithid/Htc-Sense-Freedom-Kernel.git
cd Htc-Sense-Freedom-Kernel
./build-it.sh {version #}
That's it!
Here is an example:
Error:
Code:
[email protected]:~/Development/Htc-Sense-Freedom-Kernel$ ./build-it.sh
Written by Lithid
[Error]: Expected 1 parameter, got 0.
Usage: bash build-it.sh v# [BUILD VERSION]
Good:
Code:
[email protected]:~/Development/Htc-Sense-Freedom-Kernel$ ./build-it.sh v0.3
Here is a link to the script if you are interested in seeing what I wrote. Of course it will be updated over and over again. Just figured this would be something Devs and/or users who are inspired to be devs to build a kernel without no knowledge really.
This is nice, very nice. I think I would start with building the AOSP source first. But by the time I've done that, this'll probably be finished! So thanks for the information!
This looks pretty nice thanks for the right up and links I'll definitely be checking this out some more when I get to my PC.

Not unless your computer is a mac. Building on windows is currently not supported.
This is a noble effort but what happens when a user wants to add/subtract to/from a kernel and they are not familiar with c/c++? Copy/paste will go so far especially if they can't tell the difference between a newer version of source code on someones git and the original.
Actually understanding the source is a better way of learning to build kernels instead of having an auto script do everything.
I just finally got a stable gingersense evo kernel built because certain edits (which worked on froyo kernels) would cause the kernel to lag and wifi to throw errors. If the user doesn't know how to troubleshoot, this script becomes almost moot.
I only use two scripts when I compile kernels; one to set the cc, clean the build dir, and open the dir in nautilus and the other to boot my phone into recovery to push the modules then boot into fastboot and flash the zImage.
Again it's a noble effort but things like this (and dsixdas kitchen) make it too easy for novice users to make/build these items and we end up with dozens of threads of base build items that either don't present anything marginally better than the last or unstable items due to the lack of knowledge needed to provide extended support. Dsixdas kitchen is a great tool for saving time (I use it too but learned how to root a rom by hand) but it makes it too easy for novices to build roms.
Sorry for the longwinded post and I'm not bashing the effort...just trying to point out that some things should not be made so easy for specific reasons.
Hi,
Nvidia has just release binary and tools to build ICS ROM for Tegar2 plateforme...
http://developer.nvidia.com/tegra-resources
Bye
looks like (a lot of) the stuff needed to get our own built AOSP image running properly on the TF101.
Who knows, we might see a proper ICS rom before Asus releases their own .
I cant wait to see a ics-rom on my TF101!

Ohhhh... Nice.... I'm new around here does the transformer have a dev that build aosp roms from source (not kanged)
That page has been around forever and doesn't have what is necessary to get AOSP on pretty much anything.
There's been a few accounts posting that all around the same time frame the last few days all over the Tegra based device forums.....hmmmmmm.
thanks for this!reading ics 3ad it seems that it isn't so usefull...(http://forum.xda-developers.com/showpost.php?p=21768082&postcount=361)what are you think about that?
They posted an ICS device image for ventana. We can pull the required binaries from there as a starting point rather than trying to get ICS to work with the binaries pulled from honeycomb.
I'm downloading it now.
Thanks for the post!

...we already have binaries that work with ICS, I've had builds in the public with working (and very smooth) graphics for weeks. If these ones are comparable then it'll be a nice source to pull them from, build a ROM without having to pull from a device etc. but they don't make anything any easier as you suggest.

But isn't there a new kernel in there or something to help with the (deep) sleep problems? Or is the reference board too diferent from our TF101 board?
It's all quite helpful. Cribbing stuff from a working compile is going to be easier than doing it from scratch.

There's a kernel binary, sure. It won't run on the TF101 though because as you mention it's not the same board. Ok, maybe it would run, but if it does then it'll have all the wrong peripheral setup etc. The source for the kernel is (presumably) the same nvidia source that's been available for a while and is the basis of the TF101 kernel I've been working on, so it shouldn't be significantly different.

Well, no. The _only_ things that I intend to use binaries for are the graphics drivers and bluetooth firmware. Bluetooth firmware doesn't care at all which version of android you're running, so we can ignore that. Which just leaves graphics drivers, which are already taken from an ICS ROM (fortunately the TF101 isn't the only tegra 2 tablet!).
Hi all,
i own a SbkV2 TF101 (with Dock) and always found really really difficult to install Ubuntu on my little (and oldie !) tablet.
So i was thinking about a different flavour of linux. What about ArchLinux ? Debian ? LinuxMint ?
Why no threads, no one-click tool , no support for other flavor.
Ok, i understand that the kernel underlying linux is alway the same so, the drivers, once complete, should fit any distribution, but maybe there are distributions better than others for our tf101.
And, to be honest, i became so jealous about ubuntu 12.10 on Nexus7 (ok, it's tegra3 vs tegra2, but....)
Having a full, complete linux distribution working on our tablets could allow us to many real program (not android wannabe apps), like gimp, libreoffice, mail clients, and many, many others , improving productivity dramatically.
What do you think ? i'm a visionary and the real fact is that tf101 is dying ? boh any help would be appreciated !!!
TheMac
I would love to see Mint, puppy,or a few others on here as well. I tried looking into it but could never get any image to build correctly for flashing. I'd gladly test it out if its possible to flash directly from tablet, no laptop ATM.

i don't think this is a good place for asking that. this is not a DEV thread. Anyway, i already wrote something about this.
I have running debian in my transformer. But if you want another distro you should be able to do it. This is a good place to start:
http://forum.xda-developers.com/showthread.php?t=1476835
The thread shaola mentioned is a good place to start.
Another good place to get started working with this without nuking your daily driver and messing with dualboot is to loopmount a img file on your internal storage as your root, but flash a kernel zip modified to do this and boot it up. I've been messing with it and it works pretty well.
Heres the link to the thread (again by shaola): http://forum.xda-developers.com/showthread.php?t=1537566
You can pretty easily build an image for this kind of system. I'm working on getting an Arch image booting. I used the Arch for Arm project with a tegra2 image, and just stuck that in with the loopmount kernel. I imagine LinuxMint would be pretty easy since its ubuntu based and they share packages. So again shaola's thread is a great place to start. If I get the Arch image booting ill put it up.
@SHAOLA : Thanks ! Still hoping, anyway, for a one-click-like solution (i'm the laziest man with a degree in computer science :laugh: )
@JHOLTOM : Ok, i'll stay tuned . Thanks !

I'd start by making a diff with the original kernel to see how bad the damage is first. Then you can probably manually port the Makefile to fit the old kernel and such, but it doesn't mean it'll compile, not by a long shot. You'll need to port the modules and possibly libraries too. I don't know enough about Android itself to provide instructions, but I know enough about Linux and the kernel to know this is going to be a painful task. Hope you can achieve this!

Thanks to @moreD_cn we have Linux on our tablets again. See the instructions below. I will work on a new rootfs[/FONT] real soon. For now v8.0 does FULLY FUNCTION. See the users thread for instructions!
I only quickly modified those instructions... Please let me know if I made errors. :silly:
User thread is here
Github Workdowg - TF700t-arch repo - rootfs configs and how to's on building rootfs
Github rabits tf700 repo - He has kernel and Ubuntu rootfs building stuff
My goal a the time is to keep this Arch install up to date through patches. Arch is a very cutting edge OS and doesn't take to kindly to it's files getting crossed. I will strive to make monthly base rootfs snapshots and supply an installer to make it up to date with the current patches. This will be mostly for those joining late or wish a clean start.
ToDo List:
- Power management - sleep
- CPU scaling
- Tegra drivers (At the moment they break X)
- Custom tailor rabits installer to accomplish the patching Arch will need... He has a great base for me to work off. I just need to learn the in's and outs of the Aroma Installer...
- Bluetooth
- Cameras
This is just to get the ball rolling here... This list is purposely short to allow for users to get their needs and suggestions accross to me. Through your participation, I will continue to add items YOU want and remove/switch out packages we deem are good for the whole.

Haven't forgotten the project... Just had a busy spring clean up day... I am going to try some stuff this evening...
Project on hold...
Update April 8, 2013: This project is temporarily on hold. As is the rootfs works well enough on CROMI 3.4.7. I have gotten nowhere towards getting a dual-boot to work on the stock 4.2.1 I have installed (well I got boot loops... ). The moment I can either get a bootable kernel to work or someone does, delelopment will continue...

Power management it is then... I will have to do some recovery switching this week and see if I can get the pad to:
1) use less power...2) scale the cpu's (easy really)3) stop display from sleeping after standing by (SOD - Sleep of Death)4) get suspend to work (this will be the hardest and may never be workable!)
I'm positive getting the display to go into stand by is going to be THE biggest power saver at the moment.
It has been a while... still waiting for @rabits to figure out the multiboot on the new bootloader/kernel. Until then, Arch had some big changes so this weekend I will restore one of my old CROMi setups and put up an updated basic and openbox versions for those still able to use this....
