[Kernel][D5322]MaXiMuS Kernel[UPDATE V2.1]

abcdjdj · Jul 27, 2014

Hi people,

So here's my maximus kernel for the Xperia T2 Ultra Dual (D5322). Please bear in mind that it works only on the dual sim variant. Your device won't boot if you flash it on the single sim variant!

Kernel features :-

Code:

-->Compiled with Christopher83's Linaro 4.9.1 for Cortex-A15 CPUs
-->Compiled with -O3 and many other optimizations
-->XZ compression enabled
-->Update all governors from CAF sources (no more restarts when changing to interactive governor)
-->Disable CRC in mmc driver (might give a 30% performance boost)
-->Overclocking upto 1.6 GHz
-->3x faster integer square root algorithm
-->Many oom and memory related patches and fixes
-->Enabled garbage collection for user space wakeup sources
-->Intelliplug - An intelligent hotplugging driver!
-->Cpufreq smooth scrolling patch
-->Enabled last_kmsg
-->Added intelliactive governor
-->Many more patches and fixes

Ramdisk features :-

Code:

-->Dual recovery (TWRP 2.7.1.0 and CWM 6.0.4.9) [Special thanks to DoomLoRd for his kernel - [url]http://forum.xda-developers.com/showthread.php?t=2735137[/url]]
   * Press the volume down button to access TWRP
   * Press the camera button to access CWM
   * The default recovery is TWRP (suppose you select to reboot into recovery from the rom, TWRP will get loaded)
-->Init.d support
-->ro.debuggable and ro.secure set to 0

Instructions :-
1. Download the kernel and make sure that your bootloader is unlocked. If not, then check this - http://unlockbootloader.sonymobile.com

2. Power off your phone and connect the usb cable while holding down the volume up key. You'll get a blue led on the phone.

3. Open a terminal window and use fastboot to flash the kernel. Command -

Code:

fastboot flash boot <file name>.img

4. Disconnect your phone once it is done and start it normally.

Please do read the instructions in my twrp thread (http://forum.xda-developers.com/showthread.php?t=2764408) especially step 7. Moto E also had the same problem with touch in TWRP so I have asked the Moto E dev for the solution. Mostly it will get fixed in the next version, very soon.

I have been using the default settings (ondemand with cfq) and it is pretty good. I have not added any governors or I/O schedulers in V1 as I was focusing on improving the ram problem.

Thnx for your instruction

That's not a stock based rom. It is compiled from source. Even if we had cm11, we wouldn't be able to compile that rom as Achotjan hasn't made the source code open source (might cause legal problems with Sony). And it is a kk rom so no point in trying to port it using winrar.

Do you mean to suggest that there is no need for unlocking the bootloader and install cwm for our phones to flash this kernel. I mean there is no instructions for the same in the update.

wow man u assume too much
1)You have to unlock bootloader if you want to use this kernel or any other custom rom
2)Dont install cwm
3)extract boot img from the zip of this kernel and flash it via flashtool

I posted that question because in this thread the steps should be clear to the user of this kernel on how to flash this kernel.
The instructions should start right with unlocking the bootloader to finally getting this kernel onto our devices.

I hope, you do not take my comment otherwise but until we know all the steps in one place, it is hard for users like me to run this kernel on my phone.

Yes, I have added Intelliplug and a new governor, enabled last_kmsg. Still need to work more on it. Got a lot of study load at the moment so it might get a bit delayed.

Of course I don't mind if another dev works on my sources.
