I've noticed some audio stuttering when playing music through Poweramp, when using interactive governor..

can anyone else confirm this? and @ dev - how can I contribute if a bug with this symptom is confirmed (provide logs or such)
[Xperia Z Original Android Development] Tommy-Geenexus:
This happened to me on the stock kernel too ocassionally, however i haven't faced this for some time now.

Simply report here if it happens, i'll see if it relates too my changes.

Battery life

Using all available wakelock reducing and battery life preserving methods, after some testing with the screen mostly being off (to determine the longest possible battery life), I've encountered two ways that battery goes down while using the same settings:

1) spending around 2%/hour (~50 hrs. total time) and 2) around 4-5%/hour (~20-25 hrs. total time).

This bugs me a bit since it's a big difference, and I can't find out the reason why this happens, since in both cases the drain causes (wakelocking apps, network usage etc.) have insignificant differences..

If someone would like to compare their findings with these, my main usage setting of the device is to be: 1) alert of push notifications in IM, social and mail apps, 2) to to be online on VOIP apps (thus in my case FB Messenger, FB app, Aquamail, Viber and Skype are all non-greenified and running) and 3) have sync enabled in order to stay up-to-date with contact info etc;

Bottom line, around the time when we moved from 4.4.2 and 4.4.4, the battery life jumped drastically (with my usage it went from max. 24 to max. 48 hours), which made me pretty enthusiastic; and now I'm encountering this, should I say 'idle' drain (without screen on, no misbehaving draining apps) to be randomly switching from 2% to 4-5% per hour without an apparent cause.

Could anyone relate to this and/or share their opinion?
[Xperia Z Original Android Development] langeveld024:
I think this is pretty normal usage, I would recommend to not use greenify, I used it before and since I deleted it battery became a bit better.

Also, how old is your battery? I guess 1,5/2 years old? Mine was replaced a few months ago and that makes a world of difference..
[Xperia Z Original Android Development] airlessproject:
Thanks a lot for your answer! I'll try disabling greenify and see what happens..

You're guessing right, I bought the device summer 2013.. But where I live it could be difficult to arrange getting a new battery since there isn't a dedicated Sony service center..

Anyway, assuming all this, I found it quite strange when with practically the same (bare minimum) usage, it once drains 2%/hr., other time 5%/hr.. (testing went on for many hours of not touching the phone)

I'm trying to find out what exactly causes this difference and make it happen the better way.. an additional day of not charging feels like a good reason

Also an apology to the dev if this should seem out of topic, but I decided to discuss it here as one of the main reasons for using a custom kernel is energy efficiency..
[Xperia Z Original Android Development] natibongo:
Help me

I've been able to flash it via recovery but cannot find it in the settings
[Xperia Z Original Android Development] langeveld024:
What you are trying to find in settings?

---------- Post added at 12:43 PM ---------- Previous post was at 12:40 PM ----------

I wouldn't mind a difference between 2% and 5%, might depend on mobile network location, WiFi, apps, etc.

If u really want to find out something, check wakelocks or revert to stock kernel to compare.

Also you can replace battery easily, youtube is full of guide's and tutorials for it :thumbup:
[Xperia Z Original Android Development] natibongo:
I want the kernel settings

I don't seem to find it anywhere
[Xperia Z Original Android Development] airlessproject:
I think he believes that this is an app or mod and he's looking to change kernel settings by browsing phone settings

You need an app like Fauxclock / UKM+Synapse / Trickster to change kernel settings, friend.

Whats about f2fs support ? Does this build support it ?
[Xperia Z Original Android Development] langeveld024:
Or create init.d script or use synapse.

If u still don't know how, search in this thread or revert to stock kernel cuz if u don't know what to do or how u will brick your phone if u don't read the thread :D

Btw: if u change to 1 in filesystem it will be reset to 0 after reboot

[Xperia Z Original Android Development] harism881:
Awesome

Nice work bro keep it up.....
[Xperia Z Original Android Development] :
It's oke
[Xperia Z Original Android Development] Tommy-Geenexus:
Exfat is not supported. You have to reformat your SDCard in case you want to keep this Kernel, sorry.
[Xperia Z Original Android Development] Tommy-Geenexus:
The following release will be the last release (End of Life).

Changelog:

* Added Zen I/O Scheduler and set it as default

* Disabled thermal stats, much less overhead now

* Added Security patches

* Cleaned the ramdisk

I have gone trough my repo, created a stable branch and ditched all unstable Kernel changes.

So this release should cause no issues at all.

Have fun!
[Xperia Z Original Android Development] Diatomix98:
You mean this will be the last release for KitKat or none anymore?
[Xperia Z Original Android Development] Tommy-Geenexus:
Last kk release ;).
[Xperia Z Original Android Development] :
thank you, now it's working :good:
[Xperia Z Original Android Development] natibongo:
Is dt2w included?
[Xperia Z Original Android Development] langeveld024:
Off course as u can read in this thread
[Xperia Z Original Android Development] Fodor Gábor:
This is not working for me. I have flashed, and write bad. Install aborted.
[Xperia Z Original Android Development] langeveld024:
Try other recovery or redownload zip, or flash boot.img via fastboot which will give you automatically the right recovery and then flash the kernel zip.
[Xperia Z Original Android Development] Fodor Gábor:
Ok! Thanks.
[Xperia Z Original Android Development] pxrave:
very good kernel

possible to update new wlan drivers from your new kernel?
[Xperia Z Original Android Development] Tommy-Geenexus:
Thanks.

This Kernel will not receive further updates, sorry.
[Xperia Z Original Android Development] bk1on1:
how do i disable tap2wake feature?
[Xperia Z Original Android Development] langeveld024:
Using any OC app (kernel adiutor, synapse) that supports it or using init.d script.
[Xperia Z Original Android Development] pxrave:
ok did you pretweaked the gamma settings in this kernel also?

if not can you give me a advice how?
[Xperia Z Original Android Development] FakeSmile:
Im wondering the same.
[Xperia Z Original Android Development] Tommy-Geenexus:
Yes i did.
[Xperia Z Original Android Development] langeveld024:
Where interactive and simple GPU govs causing issues u think?

Oh and BTW maybe some GPU UV , I used it on several kernel's and it greatly increased battery life and screen on time.
[Xperia Z Original Android Development] Tommy-Geenexus:
I mean very old ones like lionheart etc..

@all

For feature requests please use the request tab in devdb.
[Xperia Z Original Android Development] langeveld024:
Yeah I don't use those either. For CPU normally I use the interactive.

Ok will do bro :thumbup:
[Xperia Z Original Android Development] gripfly:
I am using the kernel now since three days and didn't noticed anything bad such as kernel panics or something.

The only things I did to save the battery life was:

removed bloatware

Auto-Sync off

automated greenify

automated wifi\mobile data (mobile data off when connected to wifi, mobile data on when disconnecting from wifi)

display brightness 50 percent

And this was my battery consuption from yesterday:

Can you add support for faux sound? Tia.?
[Xperia Z Original Android Development] Tommy-Geenexus:
Already done.

Will be included in the next version, though it may take some time to release as i'm currently quite busy.
[Xperia Z Original Android Development] :
Short question.

Will it have exfat support in future?

Thank you in advance
[Xperia Z Original Android Development] Tommy-Geenexus:
Eventually, but its not my priority.

I heard there are some patent issues with it, and the source was leaked, so i'm not sure if i'll include it.
[Xperia Z Original Android Development] :
Sorry, another thing. ;)

"NTFS r/w support" is not working for my 64GB SDcard. Not in recovery also no SDcard is showen in filemanager app when it's ntfs formatted.

the question is, is it intended for somehow attached USB* stuff only?
[Xperia Z Original Android Development] Tommy-Geenexus:
It may be that yuga doesn't support ntfs cards, this is the case on many devices such as samsung s3.

Its usb only, though i never tested it or used it myself.
[Xperia Z Original Android Development] navidsehat93:
hi. how can we change the gamma setting? faux123 kernel app gives force close at first. and there's no app for doing this. all of other apps is for nexus. help ... :(
[Xperia Z Original Android Development] langeveld024:
Use trickster mod

[Xperia Z Original Android Development] Tommy-Geenexus:
i use fauxclock, it works fine for me.
[Xperia Z Original Android Development] xvit096:
I'm also using fauxclock, kernel is smooth, no issues at all.
[Xperia Z Original Android Development] navidsehat93:
thank u very much :o

i found another problem. when i connect usb flash drive to phone, the phone freezes and then it rebouts. i installed stock kernel and the problem solved . . . but now i really want to return to your kernel, it's the best kernel i've seen. so please fix this problem . . . thank you so much :o sorry for my bad english
[Xperia Z Original Android Development] Tommy-Geenexus:
There is no problem.

If usb would be broken i wouldn't have released the kernel.

It works for me and other people just fine, might be a rom problem.
[Xperia Z Original Android Development] navidsehat93:
I'm sorry to say this but i'm sure the problem is with your kernel. now I'm on hodorkernel and i dont have any problem with OTG. before hodorkernel i installed your kernel (build 1 and 2) again and that problem still was happening. phone only reboots when i connect a usb flash driver (my usb flash is FAT32) and if i connect another device like laptop cooling pad or usb light in doesn't reboot! it's strange . . . :eek:

I'm on build 283 not 292. maybe it's the cause of this problem . . .

anyway, thank you dear for answer :)
[Xperia Z Original Android Development] Tommy-Geenexus:
This may be the problem.

As said before this kernel uses the latest sources and i recommend upgrading to .292,

I'm on stock and everything works fine for me and others.

Any specific reason you're still on .283?
[Xperia Z Original Android Development] langeveld024:
I think because existenz is still on 283.

At least I'm still on 283 because of this.. :p
[Xperia Z Original Android Development] Tommy-Geenexus:
Oh right, well.

I suppose everything works for you?

There are zero problems on newer firmware, and i won't fix bugs occuring on outdated firmwares.
[Xperia Z Original Android Development] langeveld024:
Yes everything worked very well for me! Though, I don't use exfat, NTFS, or an OTG cable..

And I agree u not fixing anything that belongs on different firmware :thumbup::D
[Xperia Z Original Android Development] TechKiel:
Nice Kernel!

ROM: eXistenZ Ultra 3.0.0

Kernel is stable and doesn't have the weird WiFI MAC Address issue. :)

Currently undervolted by -150mV but my Z could go as low as -162.5mV if only the voltage table permits. ;)

[My APQ8064 SoC is PVS: 4 (Faster)]

Battery life and Load Temperature are significantly better than stock.

Thanks a lot! :D
[Xperia Z Original Android Development] Reidroid:
Works very fine with Ultimate DualXZ Ultra v1 rom too

thanx bro
[Xperia Z Original Android Development] bk1on1:
will this kernel supports UNDER/OC?
[Xperia Z Original Android Development] Tommy-Geenexus:
Nope.
[Xperia Z Original Android Development] psycmos:
faux sound control modules!

Can you include fauxsound control modules in this kernel for we have the possibility of control input camera microphone volume!? Because in some cases we need to put that volume more lower and fauxsound have this control!! Think in that, this cam turn your kernel morw better!!! He he he cheers
[Xperia Z Original Android Development] bbeanss:
What do you mean by WiFi MAC Address issue? At the moment I'm not able to flash any custom kernels at all (I haven't tried Zombie, going to be trying it now), when I have a custom kernel of ANY kind flashed I can't connect to WiFi and I can't connect to WiFi on ANY Lollipop roms as it stands, but is this the WiFi MAC issue you speak of, or am I suffering with something completely different?

TIA

Beans
[Xperia Z Original Android Development] langeveld024:
The changed Mac address was an issue in lightning kernel for stock, although, WiFi did work normal.

If I understand correctly, u are flashing kernels on lollipop ROMs? That may be the reason WiFi don't work > u use KitKat kernel bro ;)
[Xperia Z Original Android Development] TechKiel:
The MAC Address issue also exists in Hodor Kernel though. I tried using the same solution proposed by nikhil18 in his lightning kernel for stock but it it didn't work (I've reflashed back to stock .292 before flashing Hodor Kernel)

---------- Post added at 09:13 AM ---------- Previous post was at 09:10 AM ----------

Are you sure that you're using a compatible Lollipop kernel?

What Lollipop ROM are you using? [I've tried http://www.blinkenlights.ch/ccms/android/yuga-l.html by pabx and it works fine, the phone's MAC Address is also retained]

Does your WiFi network have a MAC Filtering policy?
[Xperia Z Original Android Development] Tommy-Geenexus:
Already done, i hope to release the new build soon, altough i'm still extremely busy with exams.
[Xperia Z Original Android Development] bbeanss:
No, I'm not flashing ANY kernels over Lollipop, just using the boot img that comes with it but I can't seem ti connect to any WiFi network at all, I've tried a variety of different kernels (Meow, KMA, Hodor and a couple more) on a variety of different 4.4.4 ROMs but again, WiFi doesn't connect to any access point at all!

Although, I've just flashed Zombie Kernel and all is working fine! Could it be something to do with the WiFi modules?
[Xperia Z Original Android Development] Tommy-Geenexus:
Wifi driver is build as module.

Always flash the whole package through recovery, else the module can't be loaded.
[Xperia Z Original Android Development] comax70:
This have dt2w?
[Xperia Z Original Android Development] Tommy-Geenexus:
I'll look into it.
[Xperia Z Original Android Development] kael2404:
I think exFat support is one of the desired functions. Without that we cant play videos larger than 4 gb. I'm personally connectiong my XZ to TV via MHL so it's important for me.
[Xperia Z Original Android Development] langeveld024:
Why don't purchase a hard disk xD lol
[Xperia Z Original Android Development] TechKiel:
exFAT would also be nice since I use a Toshiba 64GB UHS-I microSD. However, I find exFAT support in Xperia Z very annoying as it tends to corrupt the filesystem quite often (Stock .292, Stock .283, HodorKernel). I've used exFAT for 2 months and I've had 2 catastrophic filesystem corruption issues. Besides that, I've also had an issue of random files getting corrupted, particularly images, which leads to the presence of empty files and folders which I could not delete. :eek:

Since then, I've switched back to FAT32. Problem solved. :victory:

exFAT on my PC works well though, just not on my Z. :(
[Xperia Z Original Android Development] Tommy-Geenexus:
As the demand is there i may add exfat in the next version.
[Xperia Z Original Android Development] kael2404:
Thanks! :D

But please be careful, because I had problems with broken filesystem, too on Hodor. 2 times some folders changed name adding sth like ".hr5cj3" and its contents disappeared :(
[Xperia Z Original Android Development] Olivier:
Thanks for not reporting the bug to me. If you want anything fixed, report a bug using DevDB AND attach logs, but DO NOT post them in another kernel thread (this could be misinterpreted, as it kinda sounds like "Kernel XY is bad, I hope yours will be better").
[Xperia Z Original Android Development] Tommy-Geenexus:
A quick question about exfat.

The driver faux imported and you picked isn't up-to-date.

Any specific reason you reverted the newer 1.2.9 exfat driver?
[Xperia Z Original Android Development] kael2404:
Don't be angry. I don't wanna to hurt you. Only few kernels including yours have exFat support and on the XZ-26 kernel I experienced similar problem (but not the same) half year ago. Can't provide logcat bcoz this occured only 2 times in unexpected moment and I cant be sure if its kernel fault or Android fault breaking files and folders. But when sdcard was broken phone didn't want to boot even to bootanimation screen on your kernel and after flashing nikihil kernel, too. Only on stock kernel booted. Formatting sdcard gave the effect, but sdcard broke itself again. I formatted it again and for 1-2 weeks till now no problem. But when sb else wrote about this before my post it is obviously that this isn't sdcard problem but sth in kernel. And I dont want somebody to build another kernel with this failure.
[Xperia Z Original Android Development] kael2404:
[MENTION=5243932]Tommy-Geenexus[/MENTION] I know not to ask about ETA, but I'm waiting if exFat will be there to install your kernel. Are you planning to release new version soon? :D
[Xperia Z Original Android Development] Tommy-Geenexus:
As soon as i finish the base for my togari kernel.
[Xperia Z Original Android Development] nighthawk696969:
Hi i like your kernel and the only thing that keeps me from using stock rom as eveyday driver is the tap 2 wake feature missing.Do you plan to include it or at least point me to a kernel that already has it?thanks in advance
[Xperia Z Original Android Development] TechKiel:
Update Center

Good day!

After using the kernel for quite some time, I find it really stable and fast, however, I have noticed that since I've flashed the kernel, the update center doesn't seem to find new updates. I tried flashing the stock kernel and it worked fine again. D:

Thanks!

EDIT: Flashed Stock .292 NCB FTF and Flashed Zombie Kernel B2 afterwards. Update center works fine again. It seems to be a rom issue? Hmm.

Great Kernel, the display popped out well but i found games too much laggy on ur kernel :-/ ...Hope to get a new version ;)
[Xperia Z Original Android Development] TechKiel:
What games?

What are your kernel settings? (CPU Freq, Governor, IO Scheduler,etc.)
[Xperia Z Original Android Development] BaDKaRmA:
Brother in arms 3, dead trigger 2... Cpu freq 1.7ghz,gvrnr-Ondemand,io schdler-cfq
[Xperia Z Original Android Development] TechKiel:
Try using

interactive

cfq

Our SoC, Qualcomm APQ8064 is prone to throttling due to temperature pressure. Overclocking it will simply make it heat up faster and would result to your device being slower. Try cooling your device while playing games. It will help a lot.

Haven't had much time to test yet, but so far so good.

This is pretty much still a WIP, i will add UKM (Synapse) support and other stuff later, i'm currently running out of time.

Ramdisk is not updated yet, haven't looked at changes, will do that later too.

The problem is that card is not even detected. Hodor kernel had the same problem at first so maybe Olivier can help you
[Xperia Z Original Android Development] Tommy-Geenexus:
I think i got the problem, may need to switch to a hacky version, should be fixed in the next build.
[Xperia Z Original Android Development] Tommy-Geenexus:
Good news, i most likely got a pocket mode working for doubletap2wake/sweep2wake.

This means no more random wakeups while the phone is in the pocket and wake gestures are enabled.

All this is done using the proximity sensor, the initial testing showed that it actually works as it's intended.
[Xperia Z Original Android Development] Borias:
Nice to hear! This is truly an awesome feature, it would be really helpful, hopefully without sacrificing battery life.

I installed your kernel on top of Existenz v3.5.5 with L Speed mod yesterday and my first impression is really good. Everything runs smoothly even if underclocked to 1350 MHz and allows extremely low voltages (about -200mv on pvs 3) and is still stable. Some more features like lower frequency steps or preservative governor would be nice, but I already like it. Keep up the good work, this really has potential!
[Xperia Z Original Android Development] langeveld024:
True that, I think the smoothness of this kernel has to do with the lean way of building and disabled logging and stuff. Keep it up Tommy !
[Xperia Z Original Android Development] xdagfg:
Using this kernel also on existenz 3.5.Its mostly smooth with some very small hang sometime(but isnt bothersome).Undervolted also right now to -175mV on all frequencies.D2w is also a welcome feature if its working.Thanks Tommy-Geenexus.
[Xperia Z Original Android Development] Tommy-Geenexus:
Thanks.

Remember, this is still in the testing stage, it's not fully finished yet.

Yes, i like my Kernels clean and bloat-free ;)

I may add CPU-Boost which is used in S800+ devices to gain more smoothness, the impact on battery life has yet to be tested.
[Xperia Z Original Android Development] xdagfg:
Can i harm the battery if i enable the fast charge feature of the kernel (zombie b3) trough trickster mod?Thanks.
[Xperia Z Original Android Development] Tommy-Geenexus:
No.

Only if your battery gets hot, which it normally shouldn't (fast charge still has lower current than AC charge, heat depends on usb cable).
