As I stated a few posts back, I used a -100mv on all steps, but with a lower cap of 700mv. With those voltages I even managed a slight overclock to 1700 or 1800 MHz.

However, each device is different, so you may or may not achieve the same results.

Hi there,

I'm happy to see you here :D

And I have a problem: With this kernel LBE crashes as soon as it gets root permissions. Is this doomkernel related?

AW: [KERNEL][T] DooMKernel {JB}(v01)[20130301]

I have the stock kernel packaged with TWRP right now installed (TWRP updated to latest version with goomanager).

Flashing this kernel zip in TWRP will override it with cwm right?

I don't know why some kernels have TWRP and some cwm, what is the better recovery? Changing it every time will make problems with the backups right? or can we cross restore?

AW: [KERNEL][T] DooMKernel {JB}(v01)[20130301]

yes. thank you very much.

it is the first kernel that I flash with recovery. so there won't be any problems if I have twrp? cause while installing your kernel, the recovery will be overwritten right?

[Sony Xperia T, TL, TX, V] Arcano:
There is something I never understood, and it may be a stupid question but: ¿why are kernels tied to a specific rom?.

I mean, given that we often flash kernels and roms independently, one would thing that they are somewhat disconnected.

I'm asking this because DooMKernel looks good enough to make me ponder between staying on AOKP with its custom features, or switching back to stock to be able to enjoy this kernel.
[Sony Xperia T, TL, TX, V] cmajetic:
AW: [KERNEL][T] DooMKernel {JB}(v01)[20130301]

it is possible that a kernel supports more roms but now we have a jb kernel and cm10 for example (and aokp 4.1 too I think) uses ics kernel. maybe we get some kernels that support stock jb and cm10.1 but we have no fully working cm10.1 for now.

[Sony Xperia T, TL, TX, V] DooMLoRD:
most changes are only related to ramdisk... if the custom ROM works on stock ramdisk then u can use my kernel on that ROM...

but ROMs like CyanogenMod require a different kernel.. as there are CM specific changes in the kernel stock based kernels wont work on CM and vice-versa...
[Sony Xperia T, TL, TX, V] Arcano:
Thank you both for your answer. I've never developed for Android, so terms like ramdisk are a bit fuzzy to me; I'll have to read some more.

I guess "porting" a kernel to work on a CM-based rom is not trivial then, right?. (I'm not asking for a port).

Hi,

Since I have changed the governor back to on demand I have absolutely no lag on wakeup. I have also OC back to 1.89 (I previously throttled back because of the lag). Using deadline for the schedular, I have tested anything else there.

I have not tested backups, I dont see there being an issue with it, but if someone has time and could take a backup then restore it, it would be nice to know...
[Sony Xperia T, TL, TX, V] r-l:
allready posted that i few pages back .. No problems with backup and restore
[Sony Xperia T, TL, TX, V] Vaizen:
Greg I don't know about you but I've noticed since the JB update from sony, always when you change a governor or the I/O after some time you'll experience lag, sometimes horrible sometimes bearable but it is solved by a reboot.

i've been testing interactive, ondemand and msm-dcvs with cfq I/O is the combinationt that works best for me.

Always reboot after changing governor or I/O on JB, that's my recommendation

[Sony Xperia T, TL, TX, V] Arcano:
Yeah, I've set 777 permissions for both the folder and the scripts, but it doesn't work. They are the same scripts I used on 4.1, so I know they are correct.

But things are getting worse: I've tried to reflash the kernel, and now it says "assert failed" when it tries to check if the device is an LT30p or Mint (which it of course is). :confused:
[Sony Xperia T, TL, TX, V] istux:
You can also flash the kernel with Flashtool after having extracted the elf from the zip ;)
[Sony Xperia T, TL, TX, V] Arcano:
Thanks, I dirty flashed the rom zip, and afterwards it let me flash the kernel.

However I am now again where I started: no undervolting possible, and init.d scripts not working.

Even ROM Toolbox, which I used on 4.1 to see the voltages now doesn't show me the voltages tab.

I don't know what else to try...

Awesome Kernel

Thanks for this kernel, got it running along side James Bond ITA 205

So heres my config, been playing with it for days:

core 0 set at 1890 MHz and core 1 set at 1512MHz

Both are set to Preformance and BFQ

All undervolted to 850mV

Enabled tunnel.decode and tunnel.audiovideo.decode in the build prop

The only problem I have atm is i cant use any other Governour appart from preformance or powersave, some of the I/O schedulers dont work nether, and I cant set the core 0 and core 1 frequenceys near each other, but this is due to my undervolt.

Again thanks DOOM keep up the good work :good:

Just a quick edit, I noticed at high loads my phone would crash so now I have 3 different profiles:

850mv for low load

900mv for medium load

935mv for high load

After a few days, I've seen the phone get sluggish once in a while, SuperSu acted a bit weird (showing notifications when they were off), init.d still does not work, although I can confirm memory issues are gone for good.

However, given this rare behavior, I'm thinking I may have some corruption in my partition tables or something like that.

¿Does anybody know what is the best way to do a full wipe of the phone?, not just a CWM wipe but a complete reset of everything: partitions, boot, kernel, etc.

how to undervolt

This is my first attempt in undervolting the cpu..

Im using trickster mod to undervolt..

In that mod, every step in undervolting undervolts the cpu by 12500 mV..

I already did two steps..

How many steps does it take to attain the minimum level ??

I dint underclock or overclock the cpu..Im using intellidemand governor..

Please help me with this..
[Sony Xperia T, TL, TX, V] Arcano:
On previous versions I managed to keep it stable starting from 700 mv and going up as the MHz increased. The new version has a lower limit of 800 mv I believe.

However, remember that each is device is different, your may be able to get lower or not than mine, only thru experimentation you will find its limits.

Hi,

I've got a problem with the OC. I cannot overlock more than 1,512GHz. The v10 version worked fine. It doesn't work if I set it through No-Frills or SetCPU. Using PureXT. Anyone with the same problem? Btw. how do I enable KSM? Thanks
[Sony Xperia T, TL, TX, V] Arcano:
I'm suffering weird behaviors whose cause I simply cannot find:

init.d scripts are not working (I created the folder in /ETC, changed permissions to 777, and did the same to the scripts inside it).

voltage levels, as seen in the vdd_table, are way wrong (see file attached). A symptom that may be related to this is the fact that ROM ToolBox is not able to change or even show them, while it could perfectly on Android 4.1.

every time I exit CWM, it warns me that root access is possibly lost and asks to fix it, even though root is working fine. No matter if I choose to do it or not, it keeps on warning me every time.

I thought something was wrong with my system, so I reset everything. Flashed a stock 4.3 FTF, and then flashed DooMKernel elf file via flashtool to have a recovery.

From there I entered CWM and flashed DaRk-L0rD's [STOCK][T][JB 4.3][9.2.A.1.205] Official Firmware - Rooted&Deodexed 03/04

And then flashed DooMKernel v11 zip, only to find I had lost baseband.

I found a post by DaRk-L0rD showing a procedure which allowed flashing his rom and DooMLord's kernel, which involved flashing his rom twice and then the kernel. I did that and recovered baseband.

And here I am, no init.d, vdd_table way off normal values, CWM complaining about losing root...

And I have absolutely no clue how to fix it.

¿Can a kind soul give me a hint as to what's wrong here?.
[Sony Xperia T, TL, TX, V] DooMLoRD:
1) strange that init.d scripts are not working... most of the code is correctly in place... odd

Thanks for your reply. I did the following to try another thing:

1- flashed with flashtool a completely stock FTF

2- fastboot flash boot kernel.elf from your kernel

3- flashed your kernel from within cwm, (just in case, I don't know if flashing via fastboot is enough)

I booted and... baseband error (no sim card), and vdd_levels were still wrong. :confused:

I am doing some more install permutations now, trying to find a pattern.

I really don't know what's going on here, as I used your kernel on 4.1 and it worked like a charm.
[Sony Xperia T, TL, TX, V] weijianhui:

[Sony Xperia T, TL, TX, V] Arcano:
After a week doing some tests, here's where I am now:

1- Init.d scripts still don't work. I don't know why, and I am not able to find anything in the boot logcat that indicates any error.

I am however able to run them manually after boot, so this doesn't worry me too much.

2- VDD interface does work indeed, and I can set the correct voltages thru a script. However, and this is something I wonder, ¿where does the original voltage table come from?. I ask this because the stock voltages I read from the interface in several roms are way above the normal stock ones (and indeed the phone felt a bit too warm after little use). Again, as I can now correct the voltages, and even undervolt them via a script after boot this does not worry me too much either, but I wonder why my stock voltage table is so weird (the one I uploaded a couple posts back).

The only thing I am unable to set as of right now is the scaling_max_freq. I have changed the sysmon.cfg to a tweaked one that allows for a slight overclocking, and logcat shows indeed the system reacting to this, but scaling_max_freq stays locked at 1512000. I cannot change it via a script, nor manually, nothing.

Curiously enough, scaling_min_freq allows me to change it without a problem (I've set it to 192000).

[Sony Xperia T, TL, TX, V] bamdadkhan:
haven't tested yet. are the default voltage values fixed? running hot was one of my problems (haven't ever touched voltages), the other one was that since philztouch cwm is not the 'default' one, and the old cwm only mounts the internal sd on the second try (on every rom btw), i couldn't use rom manager to create/restore backups. there were also issues with restoring .android_secure with the old cwm.

Cpu freq from 192 to 1242,

[Sony Xperia T, TL, TX, V] DooMLoRD:
Its not actually a problem of the number of devices supported... It's got to do more with the fact that ROMs like CM/AOSP/AOKP/Omni are all work in progress... If you mix a work-in-progress kernel (like this one) with that rom it will be tough to figure out where the stability issues arrise from... That's why I prefer supporting stock/stock based roms as we know that the Base is common...

And I have some problems with playing Modern Combat 4, it's not really fluent, lags a bit... but everything else is ok, the phone is not overheating and nothing like that, runs stable and the battery life is pretty nice in my case (after almost 20 months of usage and almost every-day charging, my battery is 1489 mAh now and it's still dying :D).

[MENTION=2784807]DooMLoRD[/MENTION]: a little bit of off topic. I hope you'll not kill me, but no one knows how to fix this problem, so I'll try to ask you!

4.3 stock ROM has a lot of problems with vocal messages in Facebook Messenger a few problems in Whatsapp, too. If you use an external app to record something from the microphone, the record is good. If you use Whatsapp, the record will have a sort of watery sound, while in Facebook Messenger it doesn't work at all and will freeze audio drivers, too (you can't take any record from any app if you don't reboot the phone first). Instead, with ANY AOSP based ROM, these problems don't exist.

Now, is it possible that 4.3 stock ROM has anything wrong in the kernel, or is it just a question of drivers? Do you think anything can be done to fix this problem?

Sorry again for the OT...:angel:
