By flashing you accept that I cannot be held responsible for anything that happens before/while/after flashing your phone, and if your CPU cooks like a waffle, your screen melts, your alarm doesn't ring and you get sacked, then I can't be held responsible

Installation Instructions
First of all, you need fastboot set up, this is something that there are plenty of tutorials set up for and so I am not going to go through the process of setting up fastboot.
Step 1:
Hold the search button on your phone while connecting it to the computer. If all goes well, you are in fastboot mode and the LED on the top of your phone (power switch) should be blue.​
Step 2:
Unless you have fastboot set up in your PATH variable, you will have to place the file into the same folder as your fastboot folder. Open a terminal/command prompt and cd into the folder the kernel is located.​
Step 3:
Now, in the terminal/cmd type, replace boot with the name of the file:
Code:
fastboot flash boot <boot>.img
fastboot reboot
If that does not flash the kernel and take you to the Sony splash screen try:
Code:
fastboot -i 0x0fce flash boot <boot>.img
fastboot -i 0x0fce reboot
Getting into the recovery:
Method 1:
When booting up the phone, a blue LED will turn on on the top of the phone, when this happens press the back button, you only need to press it once. You will end up in recovery.​
Method 2:
In a terminal emulator do:
Code:
su
reboot recovery
and your phone will automatically boot into recovery.​

Apart from the Sony ones, as stated this one is for AOSP roms, or ones which are using quallcom omx hw decoder. CM/AOKP and PlAyOSP can use this kernel (although I probably won't update PlAyOSP, too much work).
Kernel work now has become my priority, I can build over an existing build in 20s for a kernel, for a ROM it can take up to two hours, and testing a ROM takes the socks when it takes 2 hours for each testing cycle

The HW decoder codec means we'll be able to play 720 mkv files?

I am not quite sure if the decoder plays nice with 720p playback... but 720p recording does not work.

Okay, so on CM9, you'll go into your settings menu, then click on Performance. It's in Memory management. Click on zRam, then you'll be able to pick what level you want, either 10, 18, or 26%. I'm guessing that's the compression amount, but I'm not sure.
