Thanks DoomLord for your brilliant kernels with these all features. :good: :good:

I'm using .757 rooted and I use z1 stock advanced kernel because when ever I use doomkernel v10 v11 or v12 the device goes really laggy! i dont know why but it happens.when ever I flash advanced stock kernel the lags go away and the basic smoothness comes back

I really love these features on doomkernel but i have this big issue with it.

Can you help me to fix this problem?

what governor or IO s should I use to reduce this lag?

thanks
[Xperia Z1 Original Android Development] adryanodej:
i`m on .757 rom by monx with doomkernel v12 and i don`t have any lag at all .. I`m using Intelidemand governor with cfq i/o
[Xperia Z1 Original Android Development] NiM72NiK:
I just tried it. But again the same problem...

one another thing the lag is not just when the rom loads up..even in the recovery mod I have the same problem! when I press a button(for example the vol down) it takes about a second for it to come down.
[Xperia Z1 Original Android Development] poo-tang:
Nice work Doom, smooth as butter :)

Thanks for disabling DT2W (not to keen on it even when it works).

CPU overclock working fine except it seams it boots at max 2.4 and when lowered to stock values with Faux Clock (Confirmed the same with Android Tuner) it shows cores 2,3,4 are still maxed out and only 1st is limited.

+ Does anyone know why Faux Clock does not show the GPU option for Z1? Is it supposed to check with the kernel that this option is present, or are we ment to contact Faux/Paul about adding compatibility for Z1 as the option works fine on my Z?

Would rather have only the 1 or two apps I need instead of having loads of multi tools installed that only do one task each.

In versión 12 the opción from mi pimp Z1 double two tap is not present or not compatible

@ up, because it is disabled for now.

I`ve installed V12 on Criskelo V5, working very well!

Thanks for the OC!

As always, very good update, thank you!
[Xperia Z1 Original Android Development] DooMLoRD:
thanks for the info mate!

in the newer KitKat kernel many new upstream changes have been introduced.. there is now more reliance on what information is stored in the device tree files as compared to the actual kernel source... these are breaking the older custom Overclock and undervolt options... that was the key reason why many features got disabled when kitkat was released as these custom sources will have to be re-written to be compatible with newer code... just yesterday i was able to finally trace the CPU OC code... slowly i will try and bring back all the custom features which got disabled...

Z & Z1 sources have diverged... Z1 and newer devices rely on device trees (dt.img) so things are a bit different... i will talk to faux and fix this once i figure out where the new interfaces are located...
[Xperia Z1 Original Android Development] adryanodej:
try to flash from 0 .. do a fully wipe and try again .. because it`s not a kernel problem .. i think it`s about some compatibility .. or something like that.. try to flash monx rom .757 and then flash doomkernel v12.. For me works awesome!
[Xperia Z1 Original Android Development] stopcallin:
I don't know why the options don't stick and always go up to 2.4 ghz no matter on setcpu or performance control app in RomAur 7.0

Any solution?
[Xperia Z1 Original Android Development] Destroyedbeauty:
Purchase Fauxclock app and your problems will be solved ;)
[Xperia Z1 Original Android Development] stopcallin:
Yep i did but actually romaur had built in a performance control app. I am not sure will 2 of them conflict with installed at the same time. (Btw Do you know how remove the performance control app without making the option in the setting fc?)
[Xperia Z1 Original Android Development] Ashray_Vk:
Works great ! :) Thank you!
[Xperia Z1 Original Android Development] Destroyedbeauty:
Try with replacing modded settings.apk with stock one, and give 0644 (rw-r-r) permissions!
[Xperia Z1 Original Android Development] DooMLoRD:
Just got a reply from Faux:

"thanks for the feed back, I messed up. I was trying to unify the code to handle the old GPU controller and the next gen qualcomm GPU controller 8794pro+"

It should be fixed in next update of FauxClock app
[Xperia Z1 Original Android Development] Destroyedbeauty:
Are you going to get the anyone of the new Z2 units?
[Xperia Z1 Original Android Development] mikailmohammed:
Here's the question on one wants to hear. What governor and I/O are you guys using? I am looking for 1 with decent speed and battery life. Currently i have ondemand and ROW set on nofrills.
[Xperia Z1 Original Android Development] Destroyedbeauty:
Intellidemand + CFQ, will try Wheatley + CFQ on next charge and see which one that is most battery friendly..
[Xperia Z1 Original Android Development] mikailmohammed:
Will give it a go. Thanks
[Xperia Z1 Original Android Development] DooMLoRD:
it's fixed in the beta of the app!!! It will be available in next release! (check screenshot)

I do plan to get one! Hope that ppl can chip in some money (donate) for buying that phone!
[Xperia Z1 Original Android Development] Destroyedbeauty:
Will see if I can buy / afford the Xperia Z2 for a decent cheap price when I am going on a weekend travel to Alanya, Turkey, with my girlfriend, between 29th May - 5th June! If so, see you there also for some kernel awesomness! :good:
[Xperia Z1 Original Android Development] raziel123:
cpu speed

Doomlord the cpu speed does not stick, I tried underclocking it to 1.9 ghz, trickster mod shows that it gets overriden frequently...

Is there any chance of posting the v12 without the overclocked speeds?
[Xperia Z1 Original Android Development] mikailmohammed:
How to test if it sticks or not. Mines seem to stay at 2.4.
[Xperia Z1 Original Android Development] asim_mahmood007`:
Anyone please tell me if i install this kernel (v12) via flashtool on a totally stock rom 14.3.A.0.757 which is not rooted and has been downloaded and installed via sony's computer software, will it work for me, i mean will it root the device and install cwm or do i have to do anything else apart form this....

P.S my z1 is bootunlocked too.
[Xperia Z1 Original Android Development] DooMLoRD:
Just flash kernel and you are good to go...
[Xperia Z1 Original Android Development] Destroyedbeauty:
Purchase FauxClock, this app will force your desired settings to stick!
[Xperia Z1 Original Android Development] Wolfbreak:
Pimp my Z1 does the Job too. Just a alternative if you cant Purchase.
[Xperia Z1 Original Android Development] mikailmohammed:
Do you have you minimum frequency to 300mhz? I dont know if i set it lower if it will lag my phone. Not too sure about OC xperias.,

Kepp mpdecision off?
[Xperia Z1 Original Android Development] poo-tang:
I found that FauxClock can only hold back the first core for a while at a lower clock rate. If do anything to demanding and max out all cores (e.g play a game like Real Racing 3) it reverts to what is now default (2.4).

If only using device for daily tasks like messaging or browsing it seams to stick at its underclocked target.

It's a good job Doom did not jump in with any higher rates with this release. This device should be ok with being pushed up by .1 without to many issues until tested and bugs are fixed (don't hold me to this).
[Xperia Z1 Original Android Development] Destroyedbeauty:
Yes, my minimum freq is 300 Mhz (lowest possible freq until [MENTION=2784807]DooMLoRD[/MENTION] gets 192 Mhz working and enabled). The times it jumps to 1190 Mhz is because of Qualcomm M(ake)P(oor)Decision hotplug driver that is cheating to make illusion of that everything is smoother than it actually is.

Keep it online / on!

Is this anything you could do mate??

"Trolling” how? I had battery drain on 3 different devices with SwiftKey installed and then again on my Z1 with v12 DooMKernel... If reporting that is trolling to you then excuse me for living! :P

Battery drain confirmed. Don't need to report again
[Xperia Z1 Original Android Development] KarimSalloum:
What's actually not "needed" are posts like the one above this one (and this one too actually, but this one is because of yours). You're not even the dev of this kernel. :rolleyes:

I don't know about you, but when I see something being reported lots of time, I'd prefer it to stop.
[Xperia Z1 Original Android Development] tcchuin:
Reporting battery drain without logs or stats from betterbatterystats is useless.

Latest BetterBatteryStats pushed to /system with 0644 (RW-R-R) permissions, but it rejects to show / calculate kernel wakelocks. Everything else is fine though.. How to get KWL showable, so I can create an stats log to share?

Hey guys to achieve this overclock I had to fix the CPU frequency/voltage... This could be a lot different than what was there before... I have post link to the voltage table used... I recommend tweaking it to your needs as the voltages may not be optimal...

https://github.com/DooMLoRD/android...mmit/161beb29a16cc95b6ba8219ddc7d5f52c97c1184
[Xperia Z1 Original Android Development] Toldo:
Maybe you could possibly make a separate version w/out the overclock (btw. I don't see any sense in overclocking a 2.2GHz cpu in a phone, it won't be faster than it already is, OC'ing just for Antutu is pretty much not worth it)?
[Xperia Z1 Original Android Development] gregbradley:
Why have a separate version, just don't overclock to that frequency. You have to set it using a CPU app anyway, so just leave it set to stock if you want.
[Xperia Z1 Original Android Development] Toldo:
There is a saying in my country that could refer (no offence ofc): don't teach the father how to make children ;)

It is now not about the frequency, it is about voltages. I guess, if a different voltage table was needed to achieve the OC, then if I'm thinking right, the lower frequencies may also have a higher voltage rather than w/out the OC?
[Xperia Z1 Original Android Development] LLars_PL:
it increases performance in heavy games like gta, same in gpu oc, actually i think it does add performance.

-or if you mod games graphics to better ones with gl tools, it is noticable.
[Xperia Z1 Original Android Development] poo-tang:
Half the reason of a custom kernel is to be able to go beyond the limits of what a stock kernel will allow. If we put limits on everything what's the point?

Anyway some of us (e.g gamers) welcome more power where possible. Running emulator's like PPSSPP or Reicast and games like Doom3, this extra boost becomes apparent.
[Xperia Z1 Original Android Development] DooMLoRD:
Ok I have figured out a better way to select voltage based on your chip specs... Will be available in next update...
[Xperia Z1 Original Android Development] LLars_PL:
Nice, thank you!
[Xperia Z1 Original Android Development] juDGEY2k10:
Dont worry ill ask a different dev
[Xperia Z1 Original Android Development] tcchuin:
I wonder if oc makes any difference in real life when the cpu can't even run at stock highest speed for a long time before thermal throttle kicks in.
[Xperia Z1 Original Android Development] pranii23:
DooMLoRD ...Gamma Control is still in your to-do list?

The current color calibration is excellent but somehow we are supposed to have a trade off with the max brightness.

I wish the gamma control would fix that !

Very unstable Kernel, help !

Hello,

I've installed DooMKernel v12 and it's very unstable, it reboots itself after a few minutes :/ I had to downgrade to v11 version to get a "stable" version. I didn't touch to any parameters or such, it happens just after I installed it...

I have iHackers 4.1 and I've just unlocked my bootloader, so I'm new to this

Thank you !

EDIT : Tried to make a factory reset and installed a new rom (last Monx rom), and it stills reboots by itself with DooMKernel v12 (however it doesn't reboot after 2 minutes but like 10 minutes)... I don't know what to do :(
[Xperia Z1 Original Android Development] Klaus N.:
@ThibaultAnd

I can't confirm that; I'm on RomAur7.0 (clean install) and flashed v.12: No problems so far!

Also the described battery drain I can't confirm: After 12 hrs (a little email, sms and internet) I've got still 82 %. I only changed the governor to ondemand, the scheduler to cfq, and reduced the max. core frequency to 2,266 ghz.
[Xperia Z1 Original Android Development] adryanodej:
i`m on latest monx rom .757 with doomkernel v12 and i don`t have any issue .. everythink works fine until now.. that`s my second day with v12 ..
[Xperia Z1 Original Android Development] ThibaultAnd:
I don't understand why it does that...

I saw people with iHackers 4.1 + DooMKernel v12 working but it isn't stable on my phone...

I now tried to make a clean install of iHackers with DooMKernel v11 (it gives me the choice between that and iHackers kernel (which is stable)) and then upgraded to the v12 version and still the same. Did I do something wrong ?

What can I do ?

Thanks
[Xperia Z1 Original Android Development] Paradelle:
Interesting, I was using iHackers stock 2.2 and had exactly the same issue with V12. Reboots every 20 minutes, with clean install. Phone unusable. I restored a back up and I'm currently using PA. I think it's the ROM having a problem with Doom, not the other way around. Everyone else here seems to be running V12 fine. Maybe try another stock rom with V12?
[Xperia Z1 Original Android Development] LLars_PL:
it seems like the rom come in conflict somehow. I`m on v12 & criskelo v.5, running good no reboots :)
[Xperia Z1 Original Android Development] poo-tang:
Not having any noticeable batt drain today on pure stock rom after heavy use (2 - 3 hours of music full blast overclocked with Faux Sound, a little gaming, browsing, messages etc)

[Xperia Z1 Original Android Development] Destroyedbeauty:
As expected - current version of FauxClock app was the culprit behind my notorious battery drain. Wiped my Z1, installed Pure Stock v2.0 with Pimp My Z1 instead and voila - my device stays cool, stable and armored again for some heavy tasks!

You can flash this kernel, then flash SuperSU and then flash back stock kernel.
[Xperia Z1 Original Android Development] secretfile:
After having CM11 with Pimp Kernel(Everything on ECO & Powersave) went to Stock Rom ( Deodexed it myself ) and installed DooMKernel v12 battery is performing much much better, like 30% better. So your battery drain could be caused by some CPU governor or something that is deadlocking you from deep sleep but it is not kernel itself :)

Is it possible to enable some hack that pushes the lowest frequency to 300 Mhz all the time? I got some uneven battery drain, thanks to that crappy MP-Decision hotplug driver that is making my MIN freq jump to 1190 Mhz, no matter what I do.. :/

Maybe add one another Hotplug driver that is working with current WLAN modules, just an temporary solution until you can find custom PRIMA / PRONTO modules that makes Intelliplug work?
