Fusion Ultimate Kernel for all Sense-based 4.0.4 ROMs (Yes, including ViperOneS)
Latest Version: v2.1 (9/2/12)​

 */

This kernel is built from the new HTC RUU 2.31 kernel sources, which means it's compatible with any Sense 4.0.4 ROM (including ViperOneS). This is the kernel everybody has been asking for!! :victory:

How to Install

For hboot 1.09 and below:

1. Download the .7z package.
2. In it you will see a "stock" and an "overclock folder". Extract the boot-xxxxxx.zip you want.
3. Then flash the zip in TWRP recovery. It will automatically flash the boot.img for you.


For hboot 1.13 and up:

1. Download the .7z package.
2. In it you will see a "stock" and an "overclock folder". Extract the boot-xxxxxx.zip you want.
3. You have two options:

Option #1
Use TWRP's HTC Dumlock feature. It is a pretty neat workaround that allows you to flash boot.imgs in recovery even on a higher hboot.
Look here for instructions from TeamWin. If you are not comfortable with this method, then follow option #2 to manually flash in fastboot.

Option #2
In addition to flashing the zip, you will have to extract the boot.img from the package and flash it manually with fastboot. Blame HTC for the half-assed 'unlock bootloader' offering they give us. Hopefully we will get S-OFF soon...
Code: 
adb reboot bootloader
fastboot flash boot boot.img
fastboot erase cache
fastboot reboot
Look here for a guide.

FAQ

Frequently Asked Questions​

What ROMs is this kernel compatible with?

As stated in the OP, this kernel is compatible with all S4 devices running a 4.0.4 Sense-based ROM. It is 100% compatible with ViperOneS even though that uses the 2.31 RUU base. I'm betting that there were no changes in the kernel source for 2.21 and 2.31. :p


What is the best governor for me to use?

It really depends on what you're looking for. If you want performance, go with Lionheart or Ondemand. If you want battery life, go with Conservative. And if you are looking for a balance between battery life and performance, then use either SmartassV2, Interactive, or LagFree. These are just my opinions. Look here for a great reference of all the CPU governors. Test them out and decide which works best for you.


Which I/O scheduler is the best?

I personally use SIO, but you can test and decide which is the best for you. Read here to find the pros and cons of each one.


How do I overclock?

The kernel should default at 192Mhz 1.5Ghz CPU clocks. To overclock, use SetCPU, No-Frills CPU, System Tuner Lite/Pro, or any similar CPU control app. Some apps don't allow the settings to stick properly. I recommend using No-Frills or System Tuner.

CPU govenors won't stick/CPU0 stuck at max frequency????

Yes, that is a known issue with the non-default governors. I have worked hard on a fix, but I still can't figure out the problem. So basically, if you want to use a governor other than the defaults ones from a stock kernel, make sure you check up on it and make sure the settings stuck and CPU0 isn't locked at max frequency.


How do I undervolt?

Right now, the only app that works for voltage control is System Tuner. Both the Lite and Pro versions allow you to change the voltages. Do not use SetCPU as it doesn't work.
Here is the voltage table I am currently using:
Code: 
1890mhz: 1250 mV
1809mhz: 1225 mV
1728mhz: 1200 mV
1674mhz: 1175 mV
1512mhz: 1150 mV
1458mhz: 1137 mV
1404mhz: 1125 mV
1350mhz: 1125 mV
1296mhz: 1100 mV
1242mhz: 1100 mV
1188mhz: 1075 mV
1134mhz: 1075 mV
1080mhz: 1025 mV
1026mhz: 1000 mV
972mhz: 1000 mV
918mhz: 975 mV
864mhz: 975 mV
810mhz: 950 mV
756mhz: 950 mV
702mhz: 900 mV
648mhz: 900 mV
594mhz: 875 mV
540mhz: 850 mV
486mhz: 800 mV
384mhz: 725 mV
192mhz: 650 mV
Please just take these as a grain of salt; not all chips are created equal! Some devices can become an ass when it comes to undervolting, while others can starve the CPU to death and still run fine. Experiment little by little until you find your perfect voltages.


What is zRam and how does it work?

ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.

I installed it on Viper as well. UV settings were applied as set on 3.2 for 4.0.3 kernel.
I'll report back

Nice job. I didn't think this Rom could get any better. I haven't even oc or uv yet and I can feel a big difference. Curious to see how it effects battery life.

Seems to work OK on Viper, however still having problems with Smartass as on Axiom... config folder in sys/devices/system/cpu/cpufreq is sometimes not created (no smartass folder) or randomly gets deleted, so CPU0 gets locked at max freq

Ahh...so that is the source of the issue. I will have to take a look at my code then. Also, it seems to happen regardless of any governor, especially during the first few minutes after startup.

Set to smartass, rebooted, folders were there and worked fine.. but then randomly the whole folder was deleted again and cpu is locked at max all the time. Would like smartass working!

same here--ok

flashed thru fastboot and erased cache

then rebooted

Hmm...I think the issue with smartassv2 is only with the first few minutes of booting. After that, it seems to work fine and not only stick to 1.5Ghz. Can anyone confirm?
