oddeceed · Jun 5, 2014

been running since yesterday 192 - 1890 frequency, intelidemand -100mv across all frequencies hotplug enabled and possibly a couple of other tweaks ...... running smooth as

battery is good probably longest its lasted in a long time and it is mainly kernel related only thing in rom i have done to improve battery is disable fast dormancy

would love a kernel like this for omni / cm with everything you can tweak in comparison to stock / omni kernel .... IMHO if omni kernel was this good i would stay on onmi

Great that you are enjoying the kernel!

I don't build kernels for non-stock roms as it creates more issues that being good...

I will try your new amazing kernel tomorrow.

Now I'm back to stock ROM (Ultimate 4.3) from a week and I have an idea of how long is battery life and how fast is the phone.

Next week: it's time to use DooMKernel...

im loving it, it amazes me how much difference a good kernel can make to a rom

i remember reading a little while ago you saying you dont build kernels for non-stock roms .... its a shame but i sort of understand why .... i mean you do support a lot of devices after all

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...

Even if I think that an AOSP based ROM with your kernel would be the best...

which is the best governor for 60% battery saving and 40% performance? Thanks.

I don't have a Xperia T but form what I've read you got a realy good kernel. The only thing that's missing in my opinion is the GPU govenor that you already has on the todo list. You're always in the latest version of Android wich is top notch to get the most of the device. Congrats!

If I got one Xperia T I'll be sure to test your kernel.

DS-1 · Jun 7, 2014

I know it's not a main feature, but swype2wake would be a lovely option!

Its planned but the kernel sources are incompatibile with the patches I have...

Is RAM management tweaked or just changed or something? There is pretty big difference between v11 and this v12... I mean, v11 was faster and better if we talk about multitasking... I can't get more than 350MB free RAM, it usually is around 200MB. 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

).
Good job!

My phone is T. Xperia T.

I haven't changed anything related to memory management... Intelli plug bring better CPU hotplugging

@DooMLoRD: 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:

I haven't checked the old versions of DooMKenel but have you ever enabled a GPU governor on a Xperia T before? Cause if you had I could use that version untill you figure the last one out.

From what I read the Adreno 225 is a under used GPU, it has room to go up to 533MHz pushing some competitors ass these days. At the MSM8260A SoC in the Xperia T the GPU is set 200MHz paring with the Tegra 3's. But at the MSM8960 used on Atrix HD and Xperia V it is set 400MHz transpassing the Adreno 305 of Moto G set 450MHz and Mali 400MP4 on Note II set 533MHz. Using it 533MHz it could get realy close to the Mali 450MP4 used at the MT6592M set 600MHz.

I'm talk of raw power here, but this power could be used to provide a better and longer experience on the Xperia T with the CPU overcolck already provided on your unique kernel. Since I'm in a low financial situation I decided to get an aged but good smart and bet on good kernels to get me through 2 years of use I put as minimum for a smart and your work could be the key to that.

Your kernel can be used with the official ROM provided by Sony, right? And you have a ROM with your DooMKernel built in it, right?

Thanks for the attention and replies

Please keep posting your feedback about latest kernel release!

How is the RAM management now?

Is intelli_plug functionung well?

How is the battery drain?

While posting any feedback please mention all details of the kernel settings you are testing with...

If you have any good recommend settings which gave you good battery life, great performance or both please do share!!!

New feature requests along with link to patches are most welcome!!

Questions on kernel release/ETA WIL NOT BE ANSWERED!

Yesterday I was using whatsapp for half an hour and the phone started to warm up. Also it appeared a big lag. Normally it does not take that hot and slow, even when I tried to close the apps with the system task manager it was desperating. I flashed the kernel on Friday.

When "normal" use (not that intensive whatsapp conversation :silly

its very smooth, and I noticed a better performance in multitasking.:good:

I hope this can be useful for your awesome work.

I'm using v12 DoomKernel, with 1512-192 Mhz, Intellidemand/deadline and -100mV of undervolting.

Until now, the system is pretty stable. I've noticed that the system seems to be a little more "sleepy" than with the stock one. The battery duration seems to be in line with the stock kernel.

This is the first day with this kernel, so I'll post more impressions about it in the next days.

About CPU hotplug, what is Hysteresis Value? i mean i've googled it but the info was rare and it didnt help much.
