[Kernel] (011) Hybrid (DVFS-UV Control/CPU_G/LP/AVP/EMC) [Oct-12]

---

NOTICE: This is COMPATIBLE with ALL One-X Rooted Stock and Custom ROMs

For frequency control use fauxclock from Google Play

Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you

Hi XDA members and fellow One-X users:

This is my twentieth kernel hack. I want to thank XDA, and several others I cannot recall for inspiring me to venture into this unfamiliar territory for me.

What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
[Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.

THIS KERNEL is BASED ON HTC Source Code. So it is COMPATIBLE ONLY WITH HTC ICS One-X Builds.

Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).

Installation Instructions:

Here's a step by step instruction to install this kernel:

[normal mode]
1. download the above file (via phone directly or to a PC)
2. copy the downloaded zip file to /sdcard/download/
3. extract boot.img from the zip file to a location of your choice ON YOUR PC
4. open up a command window (Windows) or shell terminal (Linux/Mac)
5. connect USB cable to the phone
6. type "adb reboot bootloader"
[fastboot mode]
7. type "fastboot flash boot boot.img"
8. Once fastboot flash is completed, disconnect the USB cable
9. Select hboot using volume buttons on the phone
[recovery mode]
10. Select recovery
11. go to /sdcard/download and select the downloaded zip file and let it run its script.
12. Once the script is done, select "reboot system now"

Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...

[ Advanced Users: ]

How to find tegra3 CPU variant information with my kernels:

use terminal or file explorer of your choice with root access and read/open this following file below:

/sys/kernel/debug/t3_variant

cpu_process_id <== is the variant info range from 0~3

NEWS BULLETIN:

One-X kernel 010 is out based on HTC's 2.17 release!

Please don't hesitate to talk among yourselves and help each other out... The XDA community is what inspired me to hack kernels for everyone since everyone here is nice and helpful to each other... Keep helping each other.... Famous proverb: It's better to give than to receive...

BUGS:

Not All CHIPS ARE CREATED EQUAL

TO DO:

version 1.x.x -- Haven't thought about it yet...

Change Log

DUE TO MY EXTREMELY BUSY SCHEDULE BOTH @ WORK AND @ HOME, I WILL ONLY MAKE MAJOR ANNOUNCEMENTS ONCE PER WEEK
Open Beta may not be stable and may cause issues with your phone!

By loading open beta you have agreed to:

1. To report all random reboots with associated /proc/last_kmsg
2. To provide feedback on errors or bugs with detail phone information such as ROM, kernel version, and apps
3. Participate in Forum discussions for the beta software with others without FLAMING each other or post useless information such as:
a} Phone doesn't boot (without providing any additional information, ROM versions etc)
b} phone is too hot (without providing any additional information, ie OC freq, UV etc)

The Open Beta system is designed to have the community help each other and the developers. This way, all potential bugs are flushed out so the final released version will be stable and error free. The more actively you participate in Beta Testing the better the final product will be (you are really helping yourself to create a better community software).

If you do NOT agree with the statements above, DO NOT load my Open Beta software.

Kernel 012 Open Beta 1 is out! (BETAs ARE ALWAYS ULTIMATE + Variant Free unless I stated otherwise)

ICS ==> http://faux.androidro.ms/endeavoru/b...x123-012b1.zip

[ build 1 ]
Add Low Power (LP) core overdrive
(What is LP overdrive? LP core is capable of running up to 620 MHz @ 1.3 volts, so I simply unlocked the LP core to allow it to operate @ max freq. The overdrive also adjust the G cluster / LP core cross over point. The stock version was @ 475MHz LP / 370 MHz G-cluster, I moved the cross over point to 620MHz LP / 513 MHz G-cluster).

What does all this mean? It means LP core is now able to handle more load up to 620MHz single core before switching over to the more power hunger G-Clusters. This should theoretically save more battery life (since LP core is designed to very power frugal in Hardware). When you check the CPU stats with CPUSpy, you will see the cross over points 513MHz and 620 MHz to have high usage time. <== THIS is normal because the stats counts BOTH the LP time and the G-Cluster time so it appears to have more time than other frequencies.
