Yes I modified it to 450 MHz as others have said that was the standard.
[Xperia Z Original Android Development] Haldi4803:
well then it's time for some testing! 320mhz vs 450mhz vs 450mhz undervolted.

Did some people here already try GPU undervolting? whats a common value for 450mhz ? what seems doable ?
[Xperia Z Original Android Development] tufoz:
i flashed the zip file on my xperia Z japanese market..

but it get freezed at boot.. no logo no boot animation.. solved flashing the stock file with flashtool..

any idea to have the Xzkernel on my device?

p.s I'm on Existenz Rom..
[Xperia Z Original Android Development] -totonio-:
How can you undervolt the gpu? What am I missing?!

Have you unlocked the bootloader?
[Xperia Z Original Android Development] jpacho89:
You have to create a init.d script.

-Create a file at /system/ect/init.d

-Give proper permissions.

-Open the file and add this:

#!/system/bin/sh

echo "930000 1000000 1100000" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

-Save and close.

-Change name to a number from 00 to 99 wich doesn't match with any other file in the same folder, continued by whatever you want. For example:

06GPUUV

***The values 930000 1000000 1100000 are the GPU undervolted frequencies, you can find them in the second post I think..
[Xperia Z Original Android Development] alnikki25k:
Thank you for this. And no that's Sony default. You can go lower but I wouldn't advise. Also, 320 won't switch back because of ondemand GPU. Try with Simple governor. Also, looks like there isn't much difference 320 vs 450. That's expected considering the GPU does not eat signficant battery.

EDIT: Have you mounted system as rw?
[Xperia Z Original Android Development] shaanyt:
Is it possible for you to remove the "tweaked gamma" ? I mean, make the default gamma SONY's original gamma, cuz i feel that comparing our newly set gamma to what SONY thinks "is perfect" would make more sense. Just my thoughts. :)

EDIT: Ignore my ignorance, LOL, just updated to 18.5, it seems u've already done that. Thanks man, nice kernel hahahaha
[Xperia Z Original Android Development] Haldi4803:
P.P.S i don't think that is working! (I'm on a modified stock rom with Xposed) on 900mV on all settings. and a whole GPU run in Antutu did not crash!

Anyone else ever had Crashes because of undervolting GPU ?
[Xperia Z Original Android Development] shaanyt:
Is it possible to get 400MHz back? Cuz it originally was 400, but the real problem i seem to have is that the GPU is quite reluctant to go higher than 320, almost never at 450 unless i use PERFORMANCE on GPU, perhaps make it 320-400-450 ?
[Xperia Z Original Android Development] sea2605:
I had to laugh as I read your post :)

Was about to post the same:

I have encountered the same gpu-frequency bug, and also use 900000 mV for the gpu since over a week now and also no crashes etc.

[MENTION=4645070]alnikki25k[/MENTION]

I need to add that the governor simple has the issue, that after some time the gpu decreases clocking to 128-200mhz and won't go up again.

Even when both sliders are set for max-performance (see screenshot).

The phone gets very(!) sluggish with 128-200mhz of gpu-freq....

Hi is there anything we can do report to sony ask them to release new kernel firmware to fix the wifi wakelock?

now i have installed your 18.5 xzk and when i using data the phone is deepsleep as well. but if i connected wifi and leave in on the suspend_backoff wakelock is occurs again.

hope you can found out anything to help us for the wifi wakelock. it's drain alot of battery.
[Xperia Z Original Android Development] alnikki25k:

GPU Overclocking removed for now. And GPU undervolting also removed. I'll implement this once I can figure it out. 400 MHz is back

Gpu overclock sticks, and in some games it makes the difference!

I like the kernel. Although I think there is some problem: sometimes the device does not 'wake up'. Screen stays black but the device is on. Could this be related to the default undervolt?

I hope you can fix this problem. Otherwise, kernel is great! Good work.

So will this be possibleto have modified Stock 4.3 with XzK kernel, and 4.4.2 with MeowKernel ?

Or does that only work for Roms which use the same Kernel ?
[Xperia Z Original Android Development] joejoe23:
If I'm not wrong you can use different kernel for different rom.
[Xperia Z Original Android Development] Kocane:
Trying out 18.5. Will report back if issues, etc

But... Is it just me or does sweep/tap2wake often require you to do it twice before it works?
[Xperia Z Original Android Development] alnikki25k:
Yup. You can switch between Stock and CM/AOKP/PAC/AOSP/whatever.

It used to do that. It should be fine now, though.
[Xperia Z Original Android Development] totzkitotz:
Hi guys, been using for a few days now...Just a noob question, is there any solution for the problem I encounter? Sometimes when I locked my phone for a few minutes...Then when the time I want to unlock it...the screen stays black...Thats why, I always keep on performing force restart (by pressing the power button plus volume up) :( Does somebody also experience this kind of problem? :( thanks guys... :good:
[Xperia Z Original Android Development] Kocane:
Most of the time I think. Another thing, isn't it possible to make my power menu "reboot to recovery" work with this here kernel? Seems to me that it just does a regular boot when I try it.

Yes, I've experienced this too. Just a minute ago actually... But I also kinda had it happen with my "advanced stock kernel", so I don't know what the cause is :(. Would like some ideas from someone in the know who could have an idea of why this unable-to-wake-screen issue might happen
[Xperia Z Original Android Development] totzkitotz:

Well, I just put my phone aside for a min and when I pick it up again I cant get out of black screen... cool -.-
[Xperia Z Original Android Development] spida_singh:
I also get this issue regarding the screen not.turning back on

I think it was due to some screen voltage of some sort mentioned earlier. I could be wrong. I'm sure will have answer soon. :D

Sent from my Xperia Z
[Xperia Z Original Android Development] Kocane:
Personally, I dont do any kind of voltage edit. I enabled intelli-plug, dynamix_fsync, gpu govna "ondemand", cpu governor "smartmax".

If its possibly related to the tap2wake/sweep2wake functions, I'll gladly use the rom without.

This is the last_kmsg before the blank screen issue, I think:
[Xperia Z Original Android Development] spida_singh:
It's not a self set voltage, it's a kernel set voltage (set when built / compiled I believe) to do with screen, different to the manual voltage we can set as users. Wait until next,T release, it should be fixed. :D

Hi guys, I'm new around town.

Is the instruction to install this kernel just flashing it through CWM/TWRP?

Also does this work only for unlocked bootloaders?

Using the Existenz v5 Black Edition ROM (JB 4.3), is that compatible with this or does it have to be pure stock?

Hi I'm not sure if my bootloader is unlocked, because last time I tried to install Doomkernel v20 I got a soft-brick and people suggested that I might not have unlocked my bootloader but I have been able to install the Existenz v5 using the unlocked bootloader method.
[Xperia Z Original Android Development] alnikki25k:
XzKernel v19 is up!

Lots of fixes. Refer changelog.

Also,

Remember, if you're not using showp's MP-Decision, turn it off in MP-Decision Control > Enabled = OFF using Trickster MOD or init.d. The other MP-Decision switch is for Qualcomm only.

This is because I have noticed many forget to turn this off (from your kmsgs) and that would mean there would be two hotplug governors working at the same time and that can cause undefined problems.
[Xperia Z Original Android Development] kingrion88:
[MENTION=4645070]alnikki25k[/MENTION] once multi-rom is up can you consider to port this kernel to fit CM/AOSP/Omni 4.4?

[Xperia Z Original Android Development] Kocane:
I'm thinking in games, etc. Resolution = worse FPS, been like that always. Maybe it's different in Android?

Regardless - what's the good things about an even bigger resolution?
[Xperia Z Original Android Development] shaanyt:
He isnt really trying to push 2k resolution, he is merely saying it is possible, if people wanna do it, but since the screen itself is 1080p, it'd be quite pointless. Though if he can make 2k work, means he can make the opposite work as well, 720p instead of 1080p, or maybe just SD (480p) , this way, when u need to, u can save battery by making sure the phone doesn't need to render so much stuff. This is a custom kernel after all, gotta throw in every single feature the brain can think of. :p
[Xperia Z Original Android Development] -totonio-:
Feedback :I'm having the deep sleep problem with wifi on
[Xperia Z Original Android Development] alnikki25k:
Yup. Noticed. But, can you check how much of a percentage drop you're actually experiencing? I mean granted it doesn't deep sleep well. But I haven't had bad drops.

And with respect to 2k, as I mentioned before it's just an experiment. 720p works and works well. But I need support in SystemUI changes. I am speaking to niaboc79 about this and let's see what comes up.

Intelli-plug?

View attachment 2525764
[Xperia Z Original Android Development] alnikki25k:
Na. Scroll down and you'll find another MP-Decision Control. That refers to showp's hotplug governor. Intelli-plug is Faux's hotplug governor. Only MP-Decision at the top i.e. in your screenshot is Qualcomm's MP-Decision. Use any one.
[Xperia Z Original Android Development] Haldi4803:
Oh? So that MP decision button there is NOT for Qualcomms settings.

And another question.

If you see the CPU frequencys used, and the CPU frequencys aviable via Voltage control. There are a lot of frequencys not used.

Is that because they are in the kernel or because the Trickster App shows them?

Charge till 100. Drain till 0. Let the phone switch off. Then charge it without switching on the phone. After 3 hours switch it on and it should be calibrated.

wouldn't it be possible to deactivate one in the kernel settings ?

[Xperia Z Original Android Development] Haldi4803:
it should be called "2k Rendering" and not 2k display ;) thats it. It does render with 2k and then downscaling to 1080p.

Yes the display is limited by hardware.

P.S Anyone can confirm that Over/underCLOCKING CPU only works on Active cores ? Even if all 4 cores are active, as soon as a core goes into sleep mode and comes back active it's resetet to stock 384-1512mhz. TricksterApp s "Frequency Lock" does not help.

[MENTION=4645070]alnikki25k[/MENTION], I just made an innocent reboot after updating some xposed addons and I was stuck on the boot animation.

[Xperia Z Original Android Development] Haldi4803:
Bug Found!

Activating Abyssplug (not v2) as governor while MP-decision is deactivating and MP-decision-control by showP is activated causes the phone to crash. Freq range is 384-1512 stock.

I assume the Kernel has problems and would crash everytime with any setttings.
[Xperia Z Original Android Development] zabi1994:
I ran into this problem too.. Hard reset (Power button + Vol up for a few sec), go into recovery and wipe dalvik cache.. Worked for me..
[Xperia Z Original Android Development] alnikki25k:
Tried. It's way too stubborn to go off. I'll try something else.

I'll look into Abyssplug (it's pretty old). And I don't think the kernel crashes with any setting. It's the governors that are at fault.
[Xperia Z Original Android Development] Kocane:
Myeah it seemed to fix it but the issue quickly comes again? Especially with soft reboot it just gets stuck.
[Xperia Z Original Android Development] zabi1994:
Hmm.. It never came again for me.. Try removing that particular xposed module.. If i'm not mistaken, this problem even occurs to stock kernel on locked bootloader.. Suppose its an xposed problem.. Not kernel related..
[Xperia Z Original Android Development] Haldi4803:
For sticking CoreClock even after they're offline? i tried. doesn't seem to work. (Snake charmer was activated by default)

about the abyssplug, yeah it's the governor's fault, but governor standard settings are configured in the kernel ? so it's not an user modified error.
