Installing Uberkernel and Govnah
Overclocking the Touchpad

Installing Uberkernel and Govnah

On a desktop system, we'd overclock by dropping into the BIOS at boot time and tweaking multipliers and system clocks. On the Touchpad, we overclock by patching the kernel. Fortunately, talented hackers have already done this, and made several pre-overclocked kernels available.

The Touchpad's Qualcomm APQ8060 "Snapdragon" processor's two cores dynamically clock themselves between 192MHz and 1.2GHz when in use; unused cores can actually drop down to 0MHz to save power. Patched kernels that raise the upper limit to 1.5GHz or even higher are available. We'll stick to the 1.5GHz for now; if you want to try the 1.7 or 1.9GHz kernels, have fun...but stability problems have been reported with these higher clocks.

Before you overclock your unit, it's important to make sure you're running the latest system software. As of the time of this writing, that's version 3.0.2. To check, open the launcher, select the Settings tab, and click the System Update application. It will let you know if you need to update anything.

We'll find and install the overclocked kernel and some utilities using Preware. If you haven't yet installed Preware, go to our Root Hacking the HP Touchpad article, which will describe how to install this program manager.

Preware operates on the basis of feeds, which are repositories of programs. (Bear in mind that since "Preware" refers to the Palm Pre smartphone, much of the software will be for these phones and not the Touchpad.) We'll need to add a couple of feeds to Preware to get the stuff we need.

Step 1: Run Preware and tap the Preware menu at the top left of the screen.

Step 2: Select Manage Feeds from this menu, then scroll to the bottom of the screen to reveal the New Feed area.

Step 3: In the Name field, type webos-testing-all; in the URL field, enter http://ipkg.preware.org/feeds/webos-internals/testing/all. Leave the Is Compressed switch set to "On".

Step 4: Tap the Add Feed button at the bottom of the page. You may be prompted to "Update Feeds" at this point, but you might as well wait until you've added the next feed.

Step 5: Add one more feed with the name webos-testing-armv7 and a URL of http://ipkg.preware.org/feeds/webos-internals/testing/armv7. Again, leave the Is Compressed switch set to "On".

At this point, go ahead and let Preware update its feeds. If it doesn't offer to do this for you, tap the Preware menu at the upper left of the screen and select Update Feeds.

Now that we've configured our new feeds in Preware, we can install a patched kernel and a utility to control it. The kernel we'll be installing is called Uberkernel, and the utility is called Govnah.

Step 1: Run Preware and select List of Everything.

Step 2: Find Govnah in the list. You can tap the A-Z tab at the bottom of the screen for an alphabetically-sorted list, or tap the magnifying glass at the top right of the screen and type in the search field.

Step 3: Tap Govnah and then tap the Install button at the bottom of the screen.

Step 4: Now find and install Uberkernel in the same way.

Step 5: After you've installed Uberkernel, you must restart your Touchpad. Hold down the power button until a menu appears, then select the red Shut Down button.

After your Touchpad restarts, we can configure overclocking.

# Bug in Muffle System LoggingMartin 2011-09-11 11:44
People have reported a bug with Muffle System Logging, so it's probably best to wait until a fix is posted.

Go here: #forums.precentral.net/hp-touchpad-homebrew/297651-muffle-system-logging-blocking-email-attachments.html

but be aware that the fixes posted have had mixed results for people.

I would just like to thank the writer's of Benchmark Review's.com for their compiling information on my Little touchpad. I really love it and I thank you so much for helping to make it even better than it already is.. When you guys figure out how to install Android on it, Please let us know. Be the first..

# Change logging level without voice accountClaude 2011-09-20 23:31
To change the logging level without creating a voice account, go to "Device Info" and select "Custom Apps" from the App Menu. You can then enter the special command ##LOGS#

1. Any Bluetooth keyboard will work. I'm not aware of any "slide out" types, though.
2. No.
3. No.
4. There's nothing ready for prime time yet.

# Faster Card Animation etc..Xelaenil 2011-10-03 09:14
I was not able to install Faster Card Animations HYPER Version and Increase Touch Sensitivity and Smoothness from the preware list of applications. I found them, but at time of installation it had an error and I don't think it ever installed. Anyone else?

On the adding I encountered a couple of errors but continued on and it all seemed to work fine. Like Jedediah, when I looked at the list it was already added, so I continued with the update too.

thanks... Hopefully my touchPad will work better because of this article...

Hm. I wonder if your preware has all the correct feeds. Tap the Preware menu button in the upper left hand corner of the screen, then select "Manage Feeds" from the drop down menu. You should see six feeds whose names start with "webos-" and they should all be turned on (well, except maybe "webos-kernels-testing".

You should do a Google search for "preware" and find some PreWare forums (there are lots). The folks there can help.

Apparently the list of available feeds has changed since this article was written.

# Update 3.0.477Aaron Z 2011-11-06 13:01
Hey David,I just got my touchpad and it came with the newest webos update on it, 3.0.477. When i followed the steps here I am getting some differences. Is this guide still valid for the newest update? I hear it did fix some of these issues, as well, but I am still interested in overclocking.

# RE: Update 3.0.477David Ramsey 2011-11-06 13:06
Aaron, I must admit I don't know. The over clocking hack comprises a recompiled kernel, so I suspect it wouldn't work with the new WebOS, at least not until someone applies the hack to the new kernel. My only suggestion would be to check some of the WebOS forums around the interwebs and see what other folks have done.

Will do. Thanks. Awesome to see your dedication to this thing so long after HP has abandoned it.

By the way, I at least set the logging to minimal and Installed EOM Overload Monitoring and 3.0.477 is FLYING with just that

Yeah, I'm kinda surprised they haven't turned this stuff off in the new OS builds.
