Dude, I'm using your kernel for my XZ and will be owning a ZU this December.. it would be great to see your kernel be implemented in ZU especially the double tap to wake feature. Can you port it on ZU? it seems ZU forum lacks a developer.. :D Thanks
[Xperia Z Original Android Development] Alhaddad:
best decision ever.... thanks
[Xperia Z Original Android Development] ugurc91:
same here with smartmax sio
[Xperia Z Original Android Development] Alhaddad:
have you tried 12.5 without touch..... i'm using it with no problems
[Xperia Z Original Android Development] ankabo:
I had to many crashes, sometimes reboots, sometimes I can't turn on screen...

Back to v11, problems gone.

I don't use any touch options.

One reason is the lower l2 voltage. Will change that. Also, I am helpless regarding exfat. I'll see what else I can do.

[Xperia Z Original Android Development] Destroyedbeauty:
My recommendations to you regarding your XzK-kernel is this, like an little wishlist:

1) Continue your work, but use anything newer than 3.4.0 Linux sources. USB-On-The-Go and similar stuff = Use Doomkernel for those functions. You should focus rather on developing the most battery friendly and less demanding kernel instead, and skip all those extras. Make them downloadble as kernel modules instead for people that wants to flash & use them.

2) Tweak every governor toward more efficent battery saving. Not so the phone will become sluggish, but smooth performance and less crazy jumping to highest frequency. It's almost silly that see CPU is spending nearly all time on frequencies higher than 918 MHz, even when I am texting or doing ultra light tasks.

3) What is so good with EXFAT-filesystem? Fat32 is good enough. Make EXFAT modules flashable instead!

4) Start using Linux kernel 3.4.67 sources instead.

5) Remove all those sweep2wake / tap2wake / sweep2sleep things. Just more annoying than doing anything good, and can be created as kernel modules instead.

6) Include better battery managment. Tweak it! Tweak the governors and overall kernel power usage demand. We got Doomkernel for maximum performance, stock / Advanced stock for an combination of both and we need an kernel that is battery saving focused..

7) Include MAC Address patch!

8 ) Tweak screen gamma and color saturation for punchier colors and the less sterile stock look.

9) Etc etc..
[Xperia Z Original Android Development] Destroyedbeauty:
Didn't mean to sound rude or childish, but it is a little bit boring that stock users got two custom kernels that is near to identical.. :/

I like your work, you're an awesome developer and worth an certain donation amount, be sure on that!
[Xperia Z Original Android Development] HellRoot:
I am only facing one problem with your kernel

After flash the up and down logo in mobile data disappears from the statusbar...

Once I went back to stock all is good...

Not a big problem but surely nice to see wether data is being sent and received :)

How to fix this if you have an idea?
[Xperia Z Original Android Development] fakhreza:
Exactly what I experienced. This must be related to the missing 'data usage' option in settings under v12. :)
[Xperia Z Original Android Development] HellRoot:
I personally can't see why the kernel has anything to do with that... But glad to know I am not the only one :) thanks for letting me know
[Xperia Z Original Android Development] DrKrFfXx:
4 random reboots in 8 hours today.

Probably related to intellidemand and intelliplug mpdecision. Going to try ondemand and back to Qualcomm MP.

[Xperia Z Original Android Development] fakhreza:
Just want to share something. For those who having reboots with intellidemand gov, go to governor settings in trickster mod (or any app you're using) and set two_phase_freq to 384000.

And disable double tap to wake and sweep to wake and its kind. Had no reboots for days. Dunno if this is valid or not, at least it works for me. :p

Great work, maybe when Tap2Wake is bug-free im going back to touch option kernel.
[Xperia Z Original Android Development] mankent7:
i found a small bugs on XZK 12.5 with touch.

every time i finish a call no matter i ended up or the other side end up up the call, the screen is off and can't wake up by double tap. XZK 10-11 is working fine.
[Xperia Z Original Android Development] DrKrFfXx:
I don't know what it is but I'm having too much troubles on this release.

Devices haven't rebooted itself for a while, but now it fails to wake up whenever it feels like. I can hear notifications and see the led blinking and that stuff but I press the lock button and the screen remains black.

I'm on 12.5 no S2W and stuff.
[Xperia Z Original Android Development] Destroyedbeauty:
One question..

Is GPU underclocking working on v12.5? I mean, does it stick at the selected frequency or does it revert back to stock 400Mhz after a couple of minutes?

This will be an big battery saver if GPU can be UC to 320 (325?) Mhz and also reduce heating and stress on glass back panel..
[Xperia Z Original Android Development] crazymister:
It sticks. Tested on 627 mhz and that worked here. You can always download doomlords "gpu info" small app from the market to see the actual gpu frequency.
[Xperia Z Original Android Development] Destroyedbeauty:
Good, will lower GPU frequency asap and see how much battery life will improve!

Thanks! :good:

is this after u lowered ur GPU clock? looks very impressive
[Xperia Z Original Android Development] Destroyedbeauty:
Lowering the GPU to the 320 / 325 Mhz frequency is helping a lot, yes. The Z is an beast anyway, with too much focus on performance in the Sony pre-tuned governor set-up script file. Better tame it a little!
[Xperia Z Original Android Development] anirudhks:
Sorry a bit noob in kernel matters here.. so once I install this kernel for my Stock based Rom ( unlocked bootloder ) what app do I use ( Trickster i am guessing ? ) to lower the GPU speeds? and also should I follow the OP UV settings as well ?

Na. There's something else going. I need my phone to test this. Mostly I'll switch back to the old ramdisk. The new ramdisk is probably why even

the data usage is gone.
[Xperia Z Original Android Development] sea2605:
I'd like to give this kernel a try, but I'm not sure about following points:

1. Can I flash this kernel over doomkernel v19 in cwm?

2. Does this kernel include intellidemand (governor) yet?

3. Any drawbacks/missing features in comparison to the doomkernel?
[Xperia Z Original Android Development] beni8978:
1 you can flash it over doomkernel,just wipe cache and dalvik after.

2. Yes

3. More features than dooms,smooth and the gamma colours are better.

V13 is near to perfect, except one thing.. Something makes the kernel / phone drain battery when the phone actually should deep sleep and battery reading seems to be unstable..
[Xperia Z Original Android Development] CambaStorm:
Think I am very lucky with v13, for my at the moment it is the most stable kernel I flashed. Got more than 3 days of active time, just restart today for upgrade Xposed modules. Battery is near to 4-5 hours of screen on time on wifi. (intellidemand - 100mv undervolt) Didn't try a game, maybe tomorrow :D

Yep..same issue for me too.

Media Server seems to Run so much but maybe its just stock Rom.

I am facing some problems with Doubletap2wake after a deep sleep or a heavy game screenout..like it doesnt respond and i had to do a hard reboot...this Doubletap2wake feauture is the only thing that made me unlock my bootloader...so any possible fix/tweak for this?

Settings i use : IntelliDemand - SioPlus - with IntelliThermal enabled
[Xperia Z Original Android Development] alnikki25k:
The drain must be a calibration issue. I am going to switch back to the old RAMDisk.

Hmm. DoubleTap2Wake has to be completely re-done to make it work. For now this is the best that I can do, sorry.
[Xperia Z Original Android Development] Destroyedbeauty:
If something can be done at kernel low-level config regarding Media Server going into crazy-mode - it would be amazing!

Great! But will benchmarks be lower again with that updated kernel?(does mean lag for games) O.o
[Xperia Z Original Android Development] Destroyedbeauty:
Is 1) Media server issue fixed & patched? :D

2) Are Wifi MAC address patch included?

3) Is GPU underclocking working?

4) Intelliplug and ECO-kernel modules included?

5) Is is tweaked for even more battery life? :D

:good:
[Xperia Z Original Android Development] sea2605:
I'm currently testing your kernel and I need to congratulate you. It has all the features the current doomkernel has and currently even some more. Plus it runs a little smoother and I currently get approximativly the same battery life with it (6-7h of screen-on-time)
[Xperia Z Original Android Development] alnikki25k:
1) Yup. Gone. :)

2) Yup.

3) Yup.

[Xperia Z Original Android Development] alnikki25k:
I recommend using only one app. Trickster is where most options exist and honestly I am yet to see trickster drain my battery during sleep. Just to put things in perspective, I had my phone off the charger for 10 hours and it deep slept 9h 28 minutes with 20 minutes of screen on. So the phone was barely awake for 8 minutes over 10 hours. :good:

I was using 650 mv for 384 MHz on DK, but now 700 is lowest, please give me an opportunity to use 650!

And as I've said before it never reaches max freq. After almost 5 hours on v14 and it never reaches 1728 or 1620 (max freq 1728), it was on 1512 for 18 sec while booting. 1404 & 1458 1 sec each, 1350 ~8 min. Max freq it really reaches is 1350 MHz

My settings via init.d script:

intellidemand

384000-1728000

intelli plug + eco mode, mpdecision disabled

Great to see a v14 release. 13 was horrendous. Poor idle time, awful stability. Hope things are back to normal.

Flashed v14. I can tell the difference right away. Now the phone wakes up instantly, before it took sometimes several tries, 2-3 seconds before seeing the lock screen, and some worse times, it just failed to wake up forcing me to hard reset. 13 was broken beyond belief. Nice work on this one. Will continue trying.
