Why can't I lower the voltages to less than 800 mV? Even if I set them lower, they just come back to 800.
[Xperia Z Original Android Development] alnikki25k:
Will fix this to 700 mV

It's OK to be honest. GPU isn't as power hungry as the CPU

It's not buggy. The kernel does NOT have Simple GPU governor. Only Interactive GPU governor. TricksterMOD just lists all possible governors as there is no way of reading the list of available GPU governors at the moment

With all that news about ART and Performance Boosting Thing, it left me curious, what did Sony do with ART? I mean most xperia phones don't show that setting on stock. I don't really think they'd enable art as default either
[Xperia Z Original Android Development] Haldi4803:
ART will be deftault in Androi L not KitKat, KitKat has it just for Testing included, but not in Sony Roms. you can't even activate it. it's blocked/deleted.

Not a kernel fault.

[Xperia Z Original Android Development] Kocane:
Hmmm... Interesting. I wonder what it can be. This is a new clean install on a different android version. Still using alot of the some xposed modules though, so yeah... likely the cause lies somewhere there.

I am currently experimenting with a no hotplug kernel. Seems like this is the perfect balance for battery and performance. The performance actually seems very good.
[Xperia Z Original Android Development] androidfreak70:
Anyone flashed v25 yet? If yes give me a log about you with the kernel:D mean bugs/no bugs/speed/battery :)

I used v24 last time and got HUGE freezes and su problem! The power button take up to 8 seconds to turn on screen:(

Everyone has their own opinion/review, try it and see for yourself...

Btw i can only say that you won't be disappointed :p
[Xperia Z Original Android Development] Diatomix98:
Everything seems better than v24 especially the battery life! 2/3% overnight, performance seems ok, no problem with it though. For me, this is quite good, at least better than v24. :fingers-crossed::good:

No Sim card, but WiFi deep sleep I test on a regular basis ^^
[Xperia Z Original Android Development] David.V:
ok, thanks. so we need modded stock rom with overclocking support? :confused:
[Xperia Z Original Android Development] Kocane:
No, what you need is to wait for someone to make a kernel that support overclocking... Why you'd want to overclock, I dont understand, but that's obviously up to you, but yeah, I dont think it's something AlNikki is prioritizing so much lately...

Haldi, random question here, but battery wise (when little to no activit with screen on) do you think it matters much in terms of battery usage whether or not the phone is on 384 MHz or 702 MHz? The preservative governor is really snappy but like your testing also shows, it prefers to be on 702mhz rather than 384mhz... and I'm just wondering whether this makes a big difference
[Xperia Z Original Android Development] alnikki25k:
It all comes down to how much you use your phone. If you let the device idle at 384 MHz, then it saves a good amount of battery, maybe another hour of usage. But the smoothness suffers. Primarily because the device needs to ramp up from 384 MHz ----> 1512 MHz.

When it idles on 702 MHz, it does not really consume that much power since the device is actually idling and the clock cycles are only wasted. But, the smoothness is intact and ramping up from 702 ----> 1512 is barely a problem.

In addition, the PLLs used to generate the clock cycles need to constantly move between voltages to adapt to the 384 ----> 1512 change. This considerably drinks more juice. The same is very low in the other case. Essentially, you will save some power when it idles at 702 MHz.

You can make all these measurements and changes with my new app that will be supporting a bunch of tweaks that no other kernel has implemented yet for any android device. Specifically, I will be messing with hotplugs and thermal control. I am planning on creating a wholesome system/operation that smartly monitors the thermal state and adjusts the voltages of the CPU.
[Xperia Z Original Android Development] Kocane:
Thanks for the explanation! Hm... It's not that it only idles on 702MHz tho, it does go down to 384MHz but quickly up to 702MHz again. I just think its odd for a supposedly battery-governor to not use the lowest clock or maybe its because it does indeed even out in the end?

Either way, the smoothness kinda makes it worth it. When screen is on theres rarely a point in using a low clock I guess, it makes for keyboard lag etc which I really hate.

[Xperia Z Original Android Development] ninjy:
I don't have this problem with a stock kernel.

For the freeze, it's just when it records the video, the screen got one or two freezes during the 25sec~, and it appears in the video after too.

Humble request

I am planning to release an app with XzK-v26. A simple app for configuring the kernel. I plan to introduce certain performance profiles. This has taken a lot of work out of me. While releasing the app, I hope to raise some funds for my device development. I can't afford the Xperia Z anymore and will have to settle for a cheaper phone soon. I don't like to place ads in the app as they look ugly and DO NOT go with the android design guidelines. I humbly request anyone who wants to contribute to the development to do so through some donation. I will release the app for free, it's upto you to help me raise funds.

Thank you
[Xperia Z Original Android Development] Tommy-Geenexus:
Maybe you could optionally release the app as a paid app at the playstore or such, i think this would help you quite a bit.

Sent from my Xperia Z
[Xperia Z Original Android Development] alnikki25k:
I definitely would. But I don't want to force the payment on the users. Also, I need to buy the developer subscription.
[Xperia Z Original Android Development] BeDesireS:
But you could post a free version here in XDA and a paid one in play store.

So everyone can decide for his own and support you with buying the paid version.

And I guess that many of us would definitely go for the paid version!

Don't be stupid! You're working hard for us and doing a great job, so you deserve it!

How has the CPU governors been tweaked in v26 :)?
[Xperia Z Original Android Development] alnikki25k:
They have been made more responsive. Preservative will be at 702 MHz at idle but will switch to speeds less than 1.5 GHz. So it is more balanced. Plus, I have added touch response filter to boost the cpu speed upon touch.

Finally! The tap2wake features can now be completely turned off when not used. This will need my app of course. But no more random wakeups when in the pocket. :cowboy:
[Xperia Z Original Android Development] Kocane:
Sounds awesome :) HowThe touch response thing is for Interactive too, yeah?

So we concluded that staying on 702MHz isnt bad for the batterylife :P? Yesterday I got a screen-on-time of 5 hours with some 60% brightness. Good enough for me :) especially considering how Preservative keeps the phone snappy
[Xperia Z Original Android Development] alnikki25k:
The touch response may not be very effective with interactive unless you set tweak the parameters on your own.

Also, the app has been published to the play store. Will be available around the world in some time. :cowboy:

I've seen you started a kernel for the n7, maybe it would be helpful to upload the app source that users can translate it?

Just sayin', don't wanna stress you, just a suggestion beside.

Sent from my Xperia Z

The N7 kernel is just a very basic development. Don't have the device though.

I will upload the app source, but I will make the language and phrases in the app as simple as possible.

[Xperia Z Original Android Development] alnikki25k:
The button alignment will be fixed in the next update. The profiles are still work in progress. ? Expect an update today.

The free app will be available with XzK v26 ?
[Xperia Z Original Android Development] alnikki25k:
New App update posted on the play store. Should fix the issues.

More features will be added soon. :good:

PS: Just reboot once after installing the update. It will fix any lag caused when selecting the "Balanced" profile
[Xperia Z Original Android Development] BeDesireS:
Thanks for the quick update mate!

Till it's available at play store I have some questions about the app at all.

Will the settings stick after reboot?

What does the profile change exactly?

Because at the moment I am using trickster for changing my settings.

Is it better to delete trickster to avoid any conflicts?

Thanks for a short clarification and many thanks for your great work!

Edit: As far as I can see settings don't stick, so reboot doesn't make sense.

But settings are activated after choosing profile, so it works for me!

Gesendet von meinem C6603 mit Tapatalk
[Xperia Z Original Android Development] alnikki25k:
This app does not set at reboot. I will include that in a future update.

Yes, I suggest you remove trickster to avoid conflicts. But you could always use trickster to customize the tunables you need but don't select any performance profiles in my app. :cowboy:

Also, update v2 of the app has been posted. Includes a new GPU tunables/monitoring section. :highfive:

[Xperia Z Original Android Development] Kocane:
What exactly does the performance profiles do? Like technically. Setting it to battery saving for instance. Use of a certain governor or what?
[Xperia Z Original Android Development] Dsteppa:
In short that's it yes, to save battery etc. I guess you can see it as overclocking profiles in the BIOS.

here some more info about the governors:

Um, I opened an IM app and my phone just instantly rebooted.

This is the last_kmsg: http://pastebin.com/5Z2z1Egx

I switched to Interactive GPU governor earlier today but I dont suppose it has anything to do with that?

Doesn't matter what they do.

What matters is the end result.

The CPU crashed for lack of power. Any undervolt?

Thank you. I will explore the battery saving option. May need some governor tuning.
[Xperia Z Original Android Development] Kocane:
Ye but not much. I will increase it, I guess.

Does undervolting even pay off?

It's just of interest. Getting a little insight.

But thanks for the benchmarks.
[Xperia Z Original Android Development] alnikki25k:
I will be increasing the minimum CPU frequency response for more smoothness. For this I will be introducing a small tuning system in the app. Basically, I will ask the app load certain code and your interaction with the result decides what frequency your device will be happy with. Additionally, other system settings will be adjusted accordingly. That way, I can ensure good performance across all devices consistently. :cowboy:
[Xperia Z Original Android Development] Tommy-Geenexus:
Just because i'm curious, did you tweaked add auto_hotplug to remove hotplugging?

Because you could then add toggles to cap cores on/off and let the user decide how many cores should be online.

This was done in the Trinity kernel + app for Nexus 4 this way.

Sent from my Xperia Z
[Xperia Z Original Android Development] alnikki25k:
Nope. I completely removed the hotplug. No driver exists. I have another method for setting the number of online cores, using kernel parameters. Hassle-free. Needs no additional drivers. :D

That would be the more elegant way, nice :)

Ah, I remember the P. Fantastic display. I enjoyed mine. Unfortunately, you can't really achieve that good a viewing experience outdoors. What I could do is see if the brightness of the ALS can be increased. I need to work on that though. I'll keep you posted.

PS: You could post this as a feature request in the DB above. Would be nice to keep the thread well documented :good:
[Xperia Z Original Android Development] Destroyedbeauty:
Thank you for the good response and that you're (and other developers) actually listening to the users - that is us - of the Xperia Z!! :good:

However, if u can make this screen tweak possible - that would do a lot to the battery life, I think. The problem with the Xperia Z is that the display needs to be at the 100% to get best picture out of the display in bright sunlight outside. This tweak should do wonders, keeping the display brightness low but still retain clarity and saturation..

Increasement of the screen gamma and some custom contrast / colour levels is also warmly welcomed, together with the thing here above ^ :)

Are you gonna include erosized camera mods in your kernel in the next version?
