Xperia T overclock kernel discussion thread

Hey guys,
I'm going to make an OC kernel for Xperia T. Which featuress would you like to seen in the kernel?

Awesome dude, I was starting to get worried if I should have got the Sony Xperia T, due to slow development compared to other phones.
What feature i'm interested in is OCing the GPU higher just like other phones with the same SoC. I thought the Adreno 225 will handle games well for now but it seems it has a few lag on Asphalt 6, Nova 3, Batman and Spiderman etc, not like I play them all but it did lag. Along with a configurable GPU clock and undervolt, like the the Galaxy Nexus and S2/3.
Another one will be OCing the CPU to 2.1Ghz as most other same chip can get to, not like i'll overclock it, as there is no need really, the chip is already fast enough, but it be great to have that feature included as well. Plus undervolting as well.
Updating the linux kernel, remove all the crap in the kernel etc
Thats all for me
EDIT: Linaro would be good as well, as it seems to benefit to performance.
EDIT2: This Kernel is an good example what i'm talking about, be awesome if you could port his app interface with his permission of course, if everything goes well, I always donate quite a bit to support the developer (some motivation ).
http://forum.xda-developers.com/showthread.php?t=1871946

I would just want a better battery life. No need for more power for me or undervolting. If so, let the Kernel do it automaticly.

Is htis project still alive? jw since theres still no way to uv or oc looking into do it myself but im stillnoob at linux i would just want a way to oc to whatevers possible and same with uv

I too hope we get a better feature set, I/O schedulers and oc options,
I would like to see it set up so it boots with stock values and then tweaks can then be applied after. Also profiling would be useful, I know peetr played with some values to do with thermal throttling, would be good to see some use control for that!!! Kind of hoping that if this is not longer happening then maybe Doomlord will release one when his studies ease up a bit!

OK
As far as I know it is currently not possible to implement OC/UC/UV or new schedulars or governors without a custom kernel, hence, with a locked bootloader you will not be able to achieve these effects.

It is possible, shardul did it for neo.
Theres also an elegant script in the thread for loading them.
Take the source of the module and compile it in the source tree of stock kernel , of course you will need root at least to copy the modules to system.

Governor problem

Hi everyone, as i have been starting to fiddle around with governors i discovered that my setting won't stick and I'll have to reset them after rebooting, what could be the solution to it?
Also after researching it seem the better governor is smartassV2? Should i change any voltage or GHz for balanced performance and battery life?
Thanks all for helping out yet again:beer:

What app are you using to do this? Try trickstermod or daemon controller
And have a look at the guide linked in my signature, that might answer your questions about overclocking and undervolting
You'll have to look on a pc or on a browser on your phone

Ah right, knew I forget something. I am using vipervivo ROM with redux 0.7
The venom tweak is the one i used to change governors, and yes i did tick the setting to apply setting on boot.
Thanks mark I'll have a look at your post to decide on oc and UV

maybe u can try apps like trickstermod like mark said or SetCPU.
hope that help.

Never, ever, ****ing ever set your clock speed apps to set on boot.
Why? If you set up a frequency that your device cannot handle it will set these frequencies as soon as your phone hits the loading screen. You will not be able to boot your device as the clock settings will kick in immediately and freeze your system.

So basically wt it meant is u want to the settin keep g u set after every reboot..
If you dont check that option the settings will revert to default setting when u reboot

In case you are using setcpu then there is an option on main tab which u shud check..
It says keep the setting stable on boot..

Most roms running ics or greater have built in safety, so if the phone force closes set on boot will not apply. It is perfectly safe to set your governors and I/o on these roms. Check for info about current Rom you are running, if it has this feature go nuts and test the limits of your phone . Do your research peoples, can't stress that enough, find out what you can about your phone and current rom/radio/kernal and you won't hurt your phone. Fail to do so and risk bricking your device, its that simple.

Arm kernel discussion

I had been searching for arm kernel topic in general as I am not allowed to post in the main thread I have been using arm kernel since yesterday and what I found is the kernel wake locks in certain governors and schedulers for me the best settings that have worked are CFQ scheduler and on demand governor I also used CPU spy to figure out the frequency use by the CPU but what happens is when the phone is awake it constantly uses 500 MHz frequency instead of 200 i am not a developer but have been playing around with ROMs from quite some time.
There wasn't a discussion topic for arm so I have made this.

Ok Glad to see you reporting issues. Hmmm. Indicate your version and this may be due to SmartAssV2. Its not really tweak for stability yet.
And other users, post problems here. This way, I will directly check here to fix issues. Users who see a similar issue posted, quote that post and reply:'+1'. So, I can very much confirm its a bug, and not a single-user issue

I am using 5.11 as u had stated in some post that this is the stable version so first I had tested in jelly bam the battery was constantly draining in the battery stats was such that android os was eating some 72 % battery where as my current os is stable version of cm10 is quite stable And perfect as I am getting a good battery as well as performance only the thing is that only selected governors are working stable I will state as I use this ROM further.
Sent from my LG-P970 using xda app-developers app

Ok. Indicate the problematic governors as v5.11a will be released. This is due to the fact that people prefer the kernel based on KU5900 instead of P970.

Except for the on demand governor all governors are causing wake lock.

Yes, cm kernels are universal.

How does one make use of the wake method mod?

Trickster MOD can control screen dt2w...

Anyone use it

I flashed the hotplug zip and was able to OC to 2.4 Ghz. I haven't tried anything else yet.

Okay wanted to ask this before I flashed but actually saw your source before this was posted and was really hoping to see this kernel soon, so I couldn't wait. But question on my mind and not sure if you will know the answer yet. Since it is based off of Liquids kernel, is there a possibility this could trigger the encryption bug? Super excited to see what this kernel can do and thanks for putting it all together.

Kernel tweaker can modify cpuquiet governors which trickster can't. Nothing can change msm hotplug settings unfortunately. I would try one of those two apps and see which you like better.

Surprisingly, no. I had assumed it would, but I guess flar is still working on that. I could make you a build with it though (might be at the cost of dt2w and s2w). If I can though, I'll try to add it to his wake gesture code so we have all three.

Dbl tap to wake is easy but agreed a soft sleep will be nice. I'm getting by with Slimkat's sleep toggle but the nav sweep is a nice touch. Thanks so much for giving it a go if you do!

Sounds like this will be a good one to try. For some of those asking about S2S, what launchers are you using? I was waiting for it, and finally decided ( I'm using Inspire Launcher, of course this will work with Nova, too) to assign a double tap on the display to sleep it as well.

Woot woot!

Works well thanks.

So not sure if this is the way it is, but after flashing hotplug. Two cores and it is random which two not always the same two are locked at max speed. They never go down to 300mhz or anything slower. They just get stuck at max speed. I can change the max speed and they change with that speed but they are always whatever speed I set it to. Is this the want the hotplug driver is setup?

What Kernel|Rom combination are u using

I Tried several Roms so far, but im not getting the amount of benchscores some people get. Suggestions?

Running SlimLP and LeanKernel 1.1 decrypted. Getting about 49400 on AnTuTu. Was getting about the same on stock as well.

Elix-r, decrypted, latest supersu, and elementalx ver 0.7 for kernel. Super smooth and fast

LS or Validus ( I switch back and forth until this bug gets fixed. )
Lean Kernel v1.1 UCOC (my favorite so far)

I'm using Stock 5.0.1 with Sensei Kernel R23. It's a great balance between battery and performance and his kernel is very customizable with plenty of governors and TCP congestion control.

ElixR and Sensei.
I honestly don't know what all the tweaks are. I only use that combination since it is said to be stable. I may just switch back to stock.

Be careful not to set on boot with undervolting. Its very volatile. Try it for a while and if if doesn't crash, then set it to boot. I used mine for a day before setting it on boot

WOW!
Kernel gives all kinds of mods. Seriously better battery life or Faster performance.
13 hours since charge still at 58 % with 3 hours screen time. Mostly reading emails, forums. Several YouTube videos.
