Since SetCPU was updated today to support the tegra II chip, I thought I would just give you all a heads up. Hope to see some kernels compiled with overclocking slots soon.

Cant you overclock by hand without that?
There are a few other apps and methods to overclock. The newest version of setcpu is able to see the slots in clemsyn's kernel, but they don't exceed 1ghz.

Looks like the xoom is already OCd to 1.5. Can't wait to see some kernels for us too
Wrong section.
At any rate, I'm sure once coolbho3000 puts his overclock code in github, the kernel devs around here may be able to get these puppies overclocked as well. The difference being that the Xoom as a .36 based kernel as where we are still running .32 based kernels, so there is just as much chance that it doesn't port.
When posting, think of the content and context. This thread is about an app. But this section is for Guides, Kernels, and ROMs to be released. I know this section is where most folks spend most or all of their timing reading/posting, but there are 4 sections for a reason, to keep content organized and relevant. Let's help the mods do that by posting in the appropriate section.

Am I missing something? Isn't this in the general section?
Why do there seem to be so many self imposed forum police these days? Seems like half the posts I see are people *****ing at the op
There is a big difference between 36 and 32. Honestly, I only assume this from looking at the latest 38 rc commits and comparing the two. But it seems to be significant, even in its comments and verbosity. What's missing is cpu-tegra.c or the cpufreq driver for tegra written by Colin Cross (android dev) - instead we have NVIDIA's cryptic cpufreq.c .. I can barely understand what's going on with most code.. but it seems like our kernel version is from a time where NVIDIA's code was still being sorted thru by the aforementioned Google dev.

Yes and so can I. I can also set the governor with a script or manually. They kernel for the GTab has 2 settings....performance and powersave... and as far as I know setcpu doesnt support the .32 kernel that GTab has. It does support the .36 kernel that the xoom has.

I (one of the two mods) moved this into the General section where it should be. It had been in the Development section which wasn't the right place.
And thebadfrog is correct - we (as a community) benefit when everyone helps everyone out - including making sure posts are created in the right spot, and aren't just another variation on a question that might have been asked 15,245,332 times before.
I apologise for posting in development. I wasn't even paying attention. Thank your for moving the thread for me.

wondering if the xoom setcpu profile would jive w/ our tablets?
The gtbalet's benchmark is around 2,500. The overclocked Xoom got 2850. Standard Xoom @ 1Ghz got 2,150.
Am I missing something???? If the gtablet could be OC'd that would be huge.

The profiles won't until the AOSP frequency scaling is imported into the kernel sources - and that's not an easy process. Then the kernel will have to be compiled, etc.
Yes - it'd be nice to be OC'd - but battery life would be affected. It's a tradeoff in many ways....

On my OG Droid I like being able to drop the speed for battery savings when the screen is off if it's not in use. So there's more in it than just big numbers.
There are a number of overclocking kernels available for webOS devices:
1) UberKernel
This is the kernel that is recommended for most users. It has been comprehensively alpha and beta tested, and has predefined profiles available that have been proven to be functional and safe for all users.
Instructions on how to install and use the UberKernel, and the corresponding Govnah application which is used to set the overclocking and other kernel parameters, can be found in the Preware Homebrew Documentation app in the official Palm app catalog (yes, Palm allows instructions on how to overclock your device in the official app catalog).
The official wiki page for UberKernel is at:
http://www.webos-internals.org/wiki/Application:UberKernel
2) Other experimental kernels
In addition to the UberKernel, there are a number of other experimental kernels developed and released in separate alpha testing feeds. These experimental kernels are used for initial bleeding-edge alpha testing of new kernel development directions and new kernel features. Once these new features have been proven to be stable, they usually migrate into the next beta testing version of the UberKernel.
Instructions for how to install the experimental kernels and the conditions of use can be found at:
http://www.webos-internals.org/wiki/Testing_Feeds
The official wiki pages for these experimental kernels are at:
http://www.webos-internals.org/wiki/Application:PsychoKernel
http://www.webos-internals.org/wiki/Application:WarthogKernel
All of these kernels (both the stable versions and the experimental versions) can be installed on your webOS device using Preware. You do not need to wipe or reflash your device, nor do you need to wipe any of your data (although we do advise you to always have full backups of your data whenever you are using overclocking kernels).
Complete source code for all kernel modifications can be found in the WebOS Internals git repositories at
http://git.webos-internals.org/?p=kernels/patches.git;a=summary
and the build system for building these kernels from these patches can be found in the WebOS Internals autobuilder git repository at
http://git.webos-internals.org/?p=preware/build.git;a=summary
Any kernel hackers who wish to participate in custom kernel development for webOS devices should make themselves known in the #webos-internals IRC channel on Freenode.

Hi,
I have my AT&T GSM Palm Pre Plus running WebOS 2.1
I installed Govnah but I can't get the Uber Kernel thru Pre Ware, it says that there are not available overclockable kernels for WebOS 2.1 , I thought HP already released the kernel source.
Best Regards.

The thing with the Pre phone is that even if you flash a totally bad kernel, you simply do a recovery mode boot and use the webOS Doctor to flash back a good image.
http://www.webos-internals.org/wiki/How_To_Recover
Or you do a recovery mode initramfs boot, mount the filesystem, and move the backup kernel back into place.
http://www.webos-internals.org/wiki/Memboot
Even if you wipe the bootloader (but you would need to try *really* hard to do this, and no end-user ever has), you can still boot the OMAP over USB and flash a new bootloader.
http://www.webos-internals.org/wiki/Last_Resort_Emergency_BootLoader_Recovery
No real danger at all, since the device has been designed by Palm to be brick-proof.
There has never been a permanently bricked webOS device from homebrew or hacking. Period.

I'm a bit confused. I've added the testing feed and I see a bunch of 1.4.x kernels. None of them have any indication in the description that htey are 2.1 kernels. The Uberkernel I have was released on 1/10, so I'm assuming that it is not the right one.

If you're seeing 1.4.5 kernels, then you do not have the correct testing feed installed. This usually happens if you don't follow the wiki directions precisely and name the feed incorrectly. If you follow the wiki precisely and name the feed correctly, then Preware automatically updates the feed version on every boot.

I did follow the instructions, I think it has something to do with how the phone identifies its software. I manually added the 2.1.0 public kernel feed and tried to install Uber, but it errored out saying the kernel is not compatible.

1.4.5
I thought it was supposed to say that to get on the App Catalog. I'm definitely running 2.1.0 though and it works fine.
Edit: I looked at the instructions again and it seems like you modified the scripts, right(i metadoctored on the first day)? Is there a way to force installation of the new kernel or should I go back and rerun the whole thing with the new script?

Big fan of the AV8B Harrier II kernel here, and I'm glad to see it get on the 2.1 testing feed so quickly.
In my experience the best battery life I've experienced on any kernel, and it has been extremely stable for me as well.
How is the battery life when you have everything overclocked? I used to have a Pre -, but left cause of sprint before the plus even came out, and I am missing webos a lot. I am going to get a pre plus on verizon soon, and want to overclock it while I wait for the Pre 3 to come. I just want to know how much better the batter life is with a different kernal if at all.

I believe the battery life should be worse, not better when overclocked. However, my pre- is overclocked and I haven't noticed any difference in battery life. Of course, how you use your phone plays a big role in the battery life so your experience may differ from mine. I recommend trying it for yourself.

A lot depends on the voltage and governor of a kernel I have a nexus s clocked to 1.4 ghz with bit of undervolting and battery life is comparable to the stock kernel. Just depends on how the Dev builds it.

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!
Over 1300 seems to cause trouble on mine.
i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck
Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...
In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though
Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking
So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...
Sent from my LG-P999 using XDA App
I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)
Thanks! i always like reading knowledgeable and informative posts!

I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense?

I've finally managed to get the 6210 kernel to compile AND work with the standalone kernel modules that samsung didn't bother to provide source for (ar6000 and j4fs.) It seems that the source on opensource.samsung.com uses different config flags than the source they used to compile for the shipping tablet.
The question is: Now that I can recompile it, what do I do with it? Well, I'll think about that and come up with some interesting answers. Probably a few efficiency tweaks, modifying the init.rc to allow for init.d parsing, and.. well, I don't know what else.
(I can find the source for the ar6000 adapter and j4fs, but I was extremely determined to get things working with the existing modules. I'm stubborn.)

I've slimmed down the kernel a bit and also added support for init.d scripts (of course with no so-called ROM devs to take advantage of that, it's useless.)
I'm actually more interested in undervolting support than overclocking, but will add both around the same time. I should be able to post the kernel for the 6210 (only) sometime before the end of this year (local time.)

Actually... It appears that 'tun' is already compiled into the kernel (directly - not as a module.) You should be able to use it without loading "tun.ko".

Gary,
Correction on my assessment of your kernel. It's fine.
I'm back to stock and it's still doing what it was doing at moments and I've come to 2 conclusions:
1. The email widget I'm using on one page with a few icons
2. The Facebook widget I'm using on another page.
Pages with just icons seem to run fine.
Now I saw in your first post that you said you weren't into benchmarking for speed but have you benchmarked for battery life over the stock settings?

Only very non-scientific ones. (It's extremely difficult to ensure that exact same number of messages are pushed to my phone in a given period of time, that various forms of wifi interference are causing the same increases in power, etc.) That being said, I'm getting slightly better time on my battery with wifi set to "always on" compared to what I got on the stock kernel with wifi set to "never turn off when plugged in." (tablet was left in range of an AP in both cases.) I drop perhaps 5% in a 16 hour period with little to no screen time.
However, I'm also undervolting a bit with the custom kernel (values used are posted in another thread in this subforum), and have no active widgets beyond a single WX one that polls once/hr. I also changed the governor on my own to conservative at default settings (which saves a bit of battery as well.) Default for the kernel is ondemand which gives slightly better "snappiness."
Take care
Gary
Does it make a huge difference? Of course not. The undervolting is probably the only thing making much of a difference at all.
BTW, some of the tradeoffs between ondemand and conservative can be reduced by making some tweaks to the conservative governor:

Main thing there if you don't want to change defaults is the stuff that reduces the minimum polling interval - the MIN_SAMPLING_RATE_RATIO lines - everything else is just tuning more aggressive (performance-tuned) defaults.
Thanks for the reply Gary.
So, I'm back on your kernel and installed SetCPU. I'm still messing with the settings to see what I get as far as battery life. I've had my Tab off charge since 7am this morning and it's now 1320 and Juice plotter is showing I have 67 hours of run time (95%) as opposed to seeing numbers in the 40s before hand. My device now wakes up out of sleep as it should instead of going into a non-responsive state sending me to reboot the whole device.
Everything is looking good now.
Hi,
I just got new OP6, but I wonder which Kernel i should use with stock ROM (I wont change it, its great for me).
There is a lot of Kernels, and I'm not sure which will be best.
Thank you
Maybe try the SmurfKernel because it has GPU overclocking ability.
Someone already recommended it for me. I'll try this one then, thank you
There's actually too many kernels to choose from now which is great. Is there anything in particular you're looking for in a kernel?
Not really, it's my first OP device and just wanted to install all best stuff at the beggining of using it.
I was trying to find proper smurfkernel, but there was plenty of them to download, not sure which one I should pick.

Best will be subjective in the kernel space. Depends what you're looking for and then there'll be a top 3 choice for it. Smurf you can't go wrong with anyways.
In the downloads look for the one named 2.0.52 as that's the newest one. Then you might see a .300.710. The 300 stands for the minimum CPU clock speed. The 710 stands for the maximum GPU clock speed. If you're not into overclocking and looking for balance select the one called: SmurfKernel.2.0.52.unified.300.710.SX.plex.perm
Note: the SX, the X is a number. Be default the download will apply the performance profile. If you download the Spectrum app you can switch profiles.

Thats very helpfull, thank you mate
EX kernel is one of the most known and stable kernels.
I was using it also at my 3T and it's always my first choice.
Many options to tweak and nice app (ex kernel manager).
