[KERNEL][X10] DooMKernel - "Power to The People" [Rel: v03]{NO LONGER MAINTAINED}
this thread will now be closed and no longer maintained as the new DooMKernel (for X10 SE GB FW) will be based on FreeXperia kernel sources and will be posted in new thread
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...
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 :P
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 ]
(v03)
derived from zKernel 05072011:
kernel version 2.6.29
latest SE sources (2.1.A.0.492)
FPS cap removed
overclocked to 1.13GHz
in-call volume increased
full netfilter support (droid wall, wifi tether)
drivemapper support (2.2+ native app2sd)
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
enabled access to .config through /proc/config.gz
enabled ARM THUMBEE extensions
SLAB memory allocator
I/O scheduler activated: CFQ, Anticipatory (the inbuilt schedulers have not been disabled)
enabled TUN & TAP (VPN support)
added init.rc tweaks (thanks to erickwill)
added a special verion bootlogo
[ What do the features mean to u ]
(v03)

drivemapper support (2.2+ native app2sd)
working with basebands 54+ (67 recommended)
my additions:
confirmed to be working on all basebands (2.0.xx & 2.1.xx)
use the baseband which is best for ur region
added 192 Mhz frequency and unlocked frequencies from 128Mhz to 1267Mhz [for both series]
for full frequency-voltage table check out 2nd post
for sake of safe booting startup/bootup frequencies set at min:245Mhz, max:998Mhz
cpu voltage modulation:
S-series kernels - stock voltages
X-series kernels - undervolted
further decreased voltage (improved undervolt) for many frequencies [X-series only]
will improve battery life on X-series kernels
added 'Interactive' governor [for both series]
supposed to increase responsive of UI, for more details read this, the device will boot-up using "On Demand" as default governor, the Interactive governor needs to be selected manually using app (eg SetCPU)
compiled using GCC 4.4.3
this is supposed to increase performance of kernel
enabled EXT3, EXT4, NTFS file system support in kernel
the support is there do what u want
enabled NFS (server/client), CIFS file system support in kernel (useful app: CifsManager)
the support is there do what u want
enabled access to .config through /proc/config.gz
for those curious types who want to know more
enabled ARM THUMBEE extensions
this is supposed to improve performance for certain apps/etc
reverted back to SLAB allocator
enabled CFQ & Anticipatory I/O scheduler
options are there enjoy tweaking
enabled TUN & TAP
provides VPN support at kernel level
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 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...
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
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)
Samsung Galaxy Nexus Sony Ericsson Xperia arc Sony Ericsson Xperia X10i HTC Wildfire
If I don't reply to your PM, it simply means that I've nothing useful to say.
Looking for a nice gapps package for your favorite 4.2 ROM? Well, check this out.
Given the amount of coverage that Android receives around here, you could almost be … more
