4. flash the kernel package update.zip
5. reboot phone and enjoy the kernel

[ how to get back to stock kernel ]

I will post a clean stock kernel soon



FOR OVERCLOCKING

1. start SetCPU/NoFrills CPU Control app on ur phone (or any other app which supports overclocking) (u may get a popup asking for SuperUser permissions, click ok/yes/allow)
2. now slowly increase the MAX slider to the right (one notch at a time) to increase the maximum frequency limit
3. DO NOT JUMP TO THE LAST POSSIBLE FREQUENCY
4. SLOWLY increase the frequency one notch at a time and do stability/testing for few hours

[ tips / recommendations ]

1. before u report any battery drain issues please read this:
   [GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports
   
   
2. faux123 has posted very nice info regarding most features

[ my kernel sources ]

Just a statement regarding kernel source: The Kernel Source is released for all at GITHUB repo given below. BUT Free software does NOT mean no work or time was spent working on it. A lot of my free time has gone into patching/testing this kernel/features integrated in this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source.

Thank you !

How to use CPU Voltage Control interface


All credits for this interface go to gokhanmoral!

initially i was trying another implementation for the krait chips based on Faux123's implementation but it wasnt working propely... so I have ported the VDD interace to my kernel from gokhanmoral's commits!


device will always bootup at stock voltage table...



WARNING!

DO NOT USE TOO HIGH OR TOO LOW VOLTAGES

SLOWLY increase the voltage one notch at a time for a particular frequency and do stability/testing for few hours

once you have verified that you CPU chip can handle that voltage ONLY then "Set at boot"/Use init.d script

if you dont follow above instruction your device might bootloop




You can either use an APP (like Voltage Control) or use an init.d script to do the work...



the interface to control voltages is at:

/sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

to see current voltage table use:

[B]cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

to set voltage for a particular frequency:

[B]echo 1512000 1200 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

will set 1512Mhz freq voltage at 1200mV


to reduce voltages for ALL frequencies:

[B]echo -25 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

to increase voltages for ALL frequencies:

[B]echo +25 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

example init.d script to reduce voltages by 75mV for ALL frequencies:

[B]#!/system/bin/sh
echo -75 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

can be saved as /system/etc/init.d/99vdd

Re: [KERNEL][T] DooMKernel {JB}(v01)[Dt: 01/03]

hi mate!

glad to see you...


this is just the initial release.... i will be adding lots of features that are hallmark of DooMKernel as and when i get time

my plan is to have all devices 3.4 kernel work going in parallel...




we can run boot kernels on lock bootloaders for this device? damn i think i missed a lot

I thought you could lol it woukd be nice haha

Sent from my LT30p using xda premium

 

[gregbradley]

hi mate!

glad to see you...

No problem. Kernel works/boots fine. Obviously need a lot more testing but knowing you it will be fine.
More governors, touch recovery, UC would be great updates
How about dual boot?

we can run boot kernels on lock bootloaders for this device? damn i think i missed a lot

lol,



EDIT

There is a clean stock kernel in here

 

[DooMLoRD]

How to use Multi-Recoveries (CWM + TWRP + Philz):


Since many users have their own preference of recoveries, I have included CWM, TWRP & Philz recoveries into my kernel!!


The kernel has inbuilt triggers to enter any recovery. When the kernel is ready during bootup it will indicate by:

• showing my bootlogo
• pink/amber LED notification lighting up
• there is a small vibration

Following are the triggers:

• CWM recovery: Keep tapping VOLUME UP button
  
• TWRP recovery: Keep tapping VOLUME DOWN button
  
• Philz recovery: Keep tapping CAMERA button

Alternatively you can now also reboot into any of these selected recoveries using my Xperia Reboot app!


I have updated my Xperia Reboot app to supports multirecovery solution implemented in latest DooMKernel (Feb 1, 2014 onwards) on supported devices!

 

[gregbradley]

please check if u can enter recovery.... (i think i forgot to add that in features)

yes i can enter recovery. I didnt do anything with it, but it enters.
I also gave a link to a clean stock recovery in my previous post.

 

[POWER1FM]

If you can set the lowest cpu speed to 196 and not 384 that would be awesome!!!

Its the best tweak for battery life!!!!

Great work anyway CU soon on the Z community!!!!

 

[DooMLoRD]

How to use init.d scripts


these are small startup scripts which will get executed at bootup

these are supposed to be placed in the folder:
/system/etc/init.d/


IMPORTANT: make sure that the scripts have permissions to execute! else THEY WILL NOT RUN!

chmod 777 /system/etc/init.d/scriptname

example init.d script to reduce voltages by 75mV for ALL frequencies:

[B]#!/system/bin/sh
echo -75 > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels[/B]

can be saved as /system/etc/init.d/99vdd

 

[Arcano]

well trust me there are better ways to save battery... i will be adding all the hacks that i learnt thru my experience for saving battery...

I guess that means undervolting, ¿right?. Thank you so very much.

Kernel level Sound Control


This feature has been ported from Faux123's krait kernel sources. The sources for this feature are covered under GPL and are released along with my kernel sources at my GITHUB repo.



[ WARNING ]

high volume can damage hearing!

DooMLoRD or faux123 are not to be held responsible if this damages ur headphones/speakers/etc

USE THIS AT YOUR OWN RISK!


There are two ways to use this interface.

1. manual control through sysfs interface
2. paid app (FauxSound Audio/Sound Control)

How to use the app FauxSound Audio/Sound Control is pretty self explanatory so I will write on how to control using the sysfs interface...


BEFORE DOING ANY ADJUSTMENTS EXIT THE APPS LIKE MUSIC PLAYER/etc!!



The interface to control the sound output is located at:

[B]/sys/kernel/sound_control[/B]

it has 4 control interfaces:

• Camera MIC
  

  /sys/kernel/sound_control/gpl_cam_mic_gain

• Headphone
  

  /sys/kernel/sound_control/gpl_headphone_gain

• MIC
  

  /sys/kernel/sound_control/gpl_mic_gain

• Internal Speaker
  

  /sys/kernel/sound_control/gpl_speaker_gain

each supports gain levels from 20 (-20) to 50 (+10), base is 40 (0)
(the number in the brackets correspond to the numbers displayed in the app)

say if u want to boost headphone output (both left and right channels) then use the following command:

echo "46 46" > /sys/kernel/sound_control/gpl_headphone_gain

u can also individually increase/decrease the gain for each right and left channel



similarly other interfaces can be controlled



TIP:

do not jump to maximum values as sometimes the headphones/speakers might start distorting the audio... slowly increase and do testing for the levels which suit you!

not all accessories will work well with boosted audio output

e.g.: on my Sony MDR-XB300 headphones i start getting distorted audio beyond 48 (+8)





regards,

DooMLoRD

Nice flashing now :laugh:

backup and restore works. Overclocked on 1,728 GHz . No problem so far

 

[Vaizen]

Can't download, file is down or maybe the server is overloaded.

Tnaks Doomlord for bringing your Kernel to our XT

Edit: Seems to be the server Sorry for the annoyance

 

[MysticEnforcer]

i have read a lot about the doomkernel,
but no phone which supported him.
now i can test it by myself,
thanks :good:

just a little question,
can you change the cwm background from grey into black?

*edit*
when i try to overclock the cpu at 1890mhz,
crashes (reboots) the phone.
tried to overclock with no-frills,
trinity kernel toolbox &
i've done it slowly from 1512mhz step by step to 1890mhz.

Overclock capabilities depend on chips tolerances... Some are lucky can overclock a lot... Others cannot...

Ahh so true....

I managed to use the phone normally on 1.89 but just now I had an incoming call and the phone hung from being deep sleep, time to throttle back...

Re: [KERNEL][T] DooMKernel {JB}(v01)[Dt: 01/03]

In my opinion, this device is fast enough on stock frequencies. What we need is better battery life with stock performance.
With this kernel, my phone can finally go into deep sleep mode!

Thanks doom, keep up the good work
