[KERNEL][X10] DooMKernel - "Power to The People" [Rel: v03]{NO LONGER MAINTAINED}
this thread will now be closed and no longer maintained as the new DooMKernel (for X10 SE GB FW) will be based on FreeXperia kernel sources and will be posted in new thread
if u have never used custom kernels before please read this: [How-To] Testing or Using Custom Kernels on Xperia X10
hello guys i have finally managed to compile kernels! just started off last week and was finally able to get it to work all thanks to great help from Blagus, zdzihu, aZuZu, ThJap! and of-course a BIG thank you to all those involved in bootloader bypassing! thank you guys this would not have been possible without ur work & help! special thanks to zdzihu for the sources, the awesomeness in answering with my noob queries
inspired from the discussion with tkymgr, thank you tkymgr for that great info on CPU frequency-voltage table...
bootscreen/bootlogo/bootimage used is Sentinel196_Android_3D_Reflection from http://forum.xda-developers.com/showthread.php?t=928352 with permissions of Sentinel196, thank you Sentinel196 for that awesome image and allowing me to use it!
THANK YOU ALL WHO GAVE BACK INVALUABLE FEEDBACK OF THE TEST VERSIONS
ramdisk (slightly modded) used are:
2.1 = z's ramdisk from 05072011
2.2 = FreeX10 ramdisk
2.3/CM7.0.3 = FreeXperia beta12b ramdisk
2.3/CM7.1.0 = FreeXperia beta13 ramdisk
thank u zdzihu & jerpelea (FreeXperia Project team)!
this is just the first in a series of many more kernels that i plan to work on/release (dont ask ETA/release date, when i thinks its worth-while, i will release it)
currently i am using zkernel 05072011 as base, so the v01, v02 & v03 are derived from z's kernel sources!
ALL BASEBANDS ARE SUPPORTED!
i have personally tested on basebands 2.1.xx, and users have reported that it also works on baseband 2.0.xx
if u like the kernel dont forget to thank zdzihu cause the kernel is derived from his sources!

[ Info ]
i will be creating 2 series for the kernels:
S-series - Stock like - will be using stock SE kernel voltages, so should work on most devices w/o issues
X-series - eXtreme - will be undervolted, so as to give better battery life
i have unlocked frequencies from 128Mhz to 1267Mhz (many intermediate frequencies)!!!
thats why calling it "Power to The People" so u decide which voltages/frequencies u want
both series kernels would be having all those frequencies unlocked!
now for sake of safe booting i have hardcoded the startup/bootup frequencies to min:245, max:998 (in ramdisk) u can over-ride that using setcpu, ('set at boot' option should be used only after u have done adequate testing)
i want u guys to please test these kernels for a few hours (10-15 hrs atleast) on the ROM of ur choice!
i would recommend that u DO NOT use high frequencies for long time! this may damage ur device!
[*]the unlocked frequencies are just for temporary boost/benchmarks/showoff
[*]you have been warned!
[ Additional Info ]
ok time for some gyan!
see each cpu/chip is different
each is unique and has different tolerances
so dont directly jump to max frequency/undervolted kernel (X-series)
slowly keep increasing the frequency
check its stability for 5-10 hrs
check for random reboots
check which one is best suitable for ur device
if u start getting reboots/wlods then throttle back and use lower frequencies
if X-series kernels give u random reboots/instability then use S-series kernels
remember just because someone elses device was able to work at that frequency/voltage doesnt mean that ur phone can support/handle that frequency/voltage
[ Features ]

working with basebands 54+ (67 recommended)
my additions:
confirmed to be working on all basebands (2.0.xx & 2.1.xx)
cpu voltage modulation:
S-series kernels - stock voltages
X-series kernels - undervolted
optimized frequency-voltage table
added 192 Mhz frequency and unlocked frequencies from 128Mhz to 1267Mhz [for both series]
further decreased voltage (improved undervolt) for many frequencies [X-series only]
startup/bootup frequencies set at min:245Mhz, max:998Mhz (in ramdisk)
CPU Governors activated/added: Interactive (the inbuilt governors have not been disabled)
compiled using GCC 4.4.3
File System support (in kernel): EXT3, EXT4, NTFS, NFS (server/client), CIFS

[ DISCLAIMER ]
I AM NOT TO BE HELD RESPONSIBLE IF U DAMAGE UR PHONE / SPILL UR COFFEE / MISS UR ALARMS / ANY OTHER CALAMITY/MISHAP
[ How-To ]
take backup of ur system before using this
download the boot.img, wifi module files relevant to ur OS
make sure u have read and understood this: [How-To] Testing or Using Custom Kernels on Xperia X10
flash the boot.img & wifi module via recovery (dont flash one at a time and reboot, flash both of them one after the other, no specific sequence) then reboot into android OS
check Menu -> Settings -> About Phone -> Kernel Version to check if the kernel has changed or not
[ Downloads ]
all files provided are update.zip (Amend syntax) flashable via recovery (xRecovery 0.0.x / FreeXperia recovery)

if u are facing problems with v03 please try out the alternate v03a posted here
Older versions can be found in 3rd post
[ Troubleshooting ]
if u get stuck at bootanimation then try rebooting into recovery and wiping cache/dalvik-cache and then reboot
CM7 rom may need CM7 baseband patch (by cobrato)
IMP some users have reported (here and here) that using bootloader_bypass_files_v2.zip solved the problems/issues like "stuck at boot", "wlod while booting"... if u facing similar problems/issues please flash the bootloader_bypass_files_v2.zip via recovery and test if it worked! (thank you djkekko89 for finding this possible solution)
on v03-X (at 128Mhz) the voltage is very low (875mV) which may cause screen off reboots... if that happens then just switch to 192Mhz as lowest frequency...

Verry nice keep up your exellent Work !
cheers

Thank you , very nice

---

Good first step, I hope you good luck.
The latest time I used custom kernel it didn't go well with the ROM and my phone was a brick
Sent from my X10i using XDA App

---

Many thanks! You are great!
I think, i will have a lot of fun with your kernels...

---

i would love to test this immediately .
1)is the .zip for FreeXrecovery?
2)will i need to use the wifi.ko from Z's original source?
3.... Way to go dude, look forward to seeing your work

sorry abt that... updated 1st post!
ok so:
Ans 1] yes those are update.zip files which can be flashed via xRecovery 0.0.x/FreeXperia recovery
Ans 2] No the kernels is compiled from sources so u will need newer wifi modules any others wont work
Ans 3] thank you!

Looks good. Going to try it out now.
Just wondering, why you didn't make a complete package for all of them? (miniloader, chargemon, wifi module and kernel in one zip)

nah... its not a good idea... i personally am a BIG fan/follower of modularity! so have provide the essentials... why to make 3/4 files containing the same thing?

Mind if I make them? I'll use the FreeKernel 3.60 zip as base. Probably easier for a lot of us.

lol 1228Mhz good job... seted it to 1228Mhz and waiting for the phone to start smoking

nope! please dont do that!
dont post that cause it will cause more confusion, since we dont have unified chargemon and 3 recoveries! i am very sure ppl will have issues like "got stuck at SE text logo, now wht to do?" / "help cant get into recovery!"...
i am well aware of all those scenarios! thats why i havent posted them myself...

not yet... i am looking into it... trying to create a kernel module which will allow that.... but it will take more time and researching...
anyways till then u can choose between the undervolted (X-series) or stock voltage (S-series) kernels...

Ok now it's clear..can i know what voltage did you set for 1228 mhz?

1350mV i think... its already way over spec but hey it works sometimes on my X10
i will post full cpu freq table later...

tried both and found them very unstable. Many wlod on both.
Good work nonetheless!
