Features:

All WebOS Internals kernels follow the 7 principles of kernel design: http://bit.ly/next-gen-kernels. The Uber-Kernel incorporates the following bleeding-edge features to give you maximum control over your phone:

• 720MHz and 800MHz operating points (based on the open source OMAP3440 kernel, ported by uNiXpSyChO)
• All Linux 2.6.24 frequency governors (conservative, ondemand, powersave, userspace, performance)
• New screenstate governor, which runs at a higher speed when the screen is on and at 500MHz when the screen is off (created by uNiXpSyChO)
• OMAP3430 internal CPU temperature sensor (ported by ka6sox and rwhitby)

Available in the WebOS Internals Testing Feed.

Installation

The following guide assumes a Palm Pre or Palm Pre Plus that has the original 1.4.1.1 kernel. (Currently unavailable for Pixi/Pixi+ or other kernels.)

1. Open Preware and App Menu in the top left. (You do not have to wait for the feeds to load to complete this step.)
2. Select "Manage Feeds" and scroll to the bottom.
3. You'll need to add two feeds using the "New Feed" form.
   • webosinternals-testing-all : http://ipkg.preware.org/feeds/webos-internals/testing/all/
   • webosinternals-testing-pre : http://ipkg.preware.org/feeds/webos-internals/testing/armv7/
   1. Type the feed name in the NAME text box.
      • NOTICE: DO NOT PUT SPACES IN THE NAME. THEY RESULT IN THE FEED NOT LOADING. Instead use hyphens and make sure the name is NOT capitalized.
   2. Type or paste the URL in the URL text box
      • Make sure to delete 'http://' before pasting the URL if the URL already contains 'http://'
   3. Make sure the IS COMPRESSED option is set to YES (currently the toggle does not work, but will be fixed in future versions).
   4. Tap Add Feed and then tap Yes when the alert pops up.
4. Gesture swipe back, open the App Menu, and tap Update Feeds.
5. On Preware's homescreen, select "List of Everything" and start typing "uber-kernel" (Typing automatically starts a search that filters the list as you type.)
6. Select "Uber-Kernel (Palm Pre/Pre+)" and "Install"
7. After the installation, Preware will prompt to restart your phone. Always listen to Preware; it knows best!

Known Limitations

The Uber Kernel will not help you attract the opposite gender. It may in fact hinder you.

You: Hey there, can I buy you a drink?

Him/Her: Your pants are really hot.

You: Why thank you. I like members of the opposite sex looking at my pants.

Him/Her: No, seriously, I think they just caught on fire.

You: NOOOOOO!!!! Screw you UBERRRKERNELLL!!!

Frequently Asked Questions

My phone gets really hot during heavy use. At what temperatures should I start to worry?

This is a difficult question to answer. Over-clocking is generally uncharted territory, and as such, there are risks. One is over-heating your cpu. Another is shortening the life of your cpu because of excess heat. Initial testing done for the first over-clock-kernel (which became the Super Pre Kernel) indicated the following ranges:

• 20-40: Nothing to see here.
• 40-45: Generally acceptable, but avoid long durations of high temperatures.
• 45-50: Unacceptable. Take your phone off the charger, put it in Airplane mode to turn off the radios, and open the slider to increase surface area. Allow the phone to return to at least 35.
• 50+: Duck and cover; battery explosion imminent.
