Does it effect battery usage and performance....which do you suggest is the best....if ondemand scales, so does that governor is best for everyday usage....
[Sony Xperia Z Ultra] pemell:
Made some more testing and it turns out that GPU target_freq is set on a high when not on charger and lower when charging.

It should be the other way around.

The GPU should look to preserve power when you're not charging.
[Sony Xperia Z Ultra] dbolivar:
Confirmed... I've noticed this behavior (GPU idling at 450 MHz) for some time now, but considered it to be "normal"; now that you brought it up with more testing, it made me think something may not be right. With CM11 kernel, and stock Sony kernel, the GPU idles at 320 MHz when using msm-adreno-tz. And weird enough, with either of the kernels (including DooMKernel), when the GPU has some load it scales down sometimes. It's like it's idling at 320 or 450 MHz, and when there's some load, it "wakes up" and begins to do proper frequency scaling. If that's good for battery I don't know; perhaps they did that to make UI smoother, making a trade off with battery life?

With simple_ondemand there's proper scaling, with the GPU idling at 200 MHz. But I noticed some stuttering / lags... Perhaps it will benefit from some tweaking, as you are already doing.
[Sony Xperia Z Ultra] skudo101:
i'm using Monx ROM v 06.02 (base .757), can i flash this Kernel? My device is locked Bootloader. Thanks in advance :)
[Sony Xperia Z Ultra] blueether:
short: No

long: Did you read any of the thread?
[Sony Xperia Z Ultra] joluke:
short answer: you can but...

long: you cannot use with locked bootloader but yes You can run with unlocked :P

[Sony Xperia Z Ultra] beenoliu:
Why can't increase / decrease CPU voltage in all CPU control apps now?

I flash the v18 kernel on my Z Ultra (unlocked boot loader) already.
[Sony Xperia Z Ultra] beenoliu:
Why can't take photo after flash the v18 kernel?

It can take photo using front camera but rear camera can't.

Rear camera can't use focus and can't take photo.

Problem fixed.
[Sony Xperia Z Ultra] ShadowVlican:
i've been using simple_ondemand for a couple days since you've mentioned it...

i can confirm the stuttering and lags... it's quite annoying actually, so i'll go back to default

great detective work :good:
[Sony Xperia Z Ultra] TimeTurn:
Got random total lockups followed by a reboot with this kernel. Flashed a root boot.img for 757 and everything works fine now.
[Sony Xperia Z Ultra] DooMLoRD:
so instead of starting another thread I think I will start releasing my official DooMKernel in this thread itself...

Check my Z2 kernel thread for details of upcoming changes!

basically everything from v05 and onwards of my Z2 kernel WILL BE ported over to the Z1/Z Ultra :) and may be even more if these damn custom wlan modules start working!

Since I have the ZU GPe my first priority was to get the normal Sony ROMs booting on it so that i can check if kernel ment for ZU was stable... now that i have the latest .757 ROM booting on it too (check screenshot a few posts back) I can do all testing at then upload :)

[ IMP NOTE ]

1] starting from v19 onwards you will not be able to get back to stock kernel directly as the wifi related files get changed while flashing kernel!

2] I will release updated advanced stock kernel package to support easily going back to stock kernel!

3] THIS BREAKS exFAT compatibility for now! if you have exFAT based external SDCARD IT WILL NOT WORK WITH THIS KERNEL VERSION!

I am working on fixing this but it will take some time!

4] Sony Z Ultra GPe is now officially supported! I will release kernel for that device later...

[Sony Xperia Z Ultra] dbolivar:
Kernel working VERY smoothly, I feel that with the same CPU governor settings I've been using, but switching to intelli-plug, I get a smoother experience! Thanks DooMLoRD!

I have a question: the Simple GPU algorithm tweaks only work if we select "simple_ondemand" GPU governor, right? Does it have any effect for other governors, like msm-adreno-tz?
[Sony Xperia Z Ultra] DooMLoRD:
it affects all governors...

recommend using it with msm-adreno-tz

if u play with the algo settings u will see that u can trigger the GPU scaling to be more battery friendly (prefer lower clocks) or more performance (prefer higher clocks)...
[Sony Xperia Z Ultra] texaspledge:
Awesome. Just to confirm though, can I flash on GPe? You noted its now supported but also mentioned you would release kernel later for that device. I'm easily confused :)
[Sony Xperia Z Ultra] DooMLoRD:
unfortunately the stock Sony kernel sources are NOT compatible with the GPe ROM... thats why I am creating a separate kernel release for the GPe...

[Sony Xperia Z Ultra] shaolin95:
No Issue for me on Wifi either. So far so good.

Anyone playing with the voltages? I am going to start tweaking to see how log I can go while keeping max OC.

Any recommendations of governors, IO etc for performance on V19?
[Sony Xperia Z Ultra] iBuzman:
+24 mV across the board just for benchmarking :D thx for the wifi update - mine seems to have settled (don't know what was going on earlier??)
[Sony Xperia Z Ultra] shaolin95:
You are adding voltage to keep it stable? I am planning to drop mine since so far with the stock voltages it has been stable. :D
[Sony Xperia Z Ultra] iBuzman:
Just for fun to see the performance impact - I usually don't bother with uv or ov for that matter, slightly less battery use is usually at expense of something (performance or stability etc) - but that's probably because I don't generally know what I'm doing :)
[Sony Xperia Z Ultra] shaolin95:
I normally only do it to try keeping the phone as cool as possible and its just a lot of trail and error :D

I will report my findings even though each phone will be different.

Yes, temp a good reason. Sgs3 needed uv to stay cool from memory.

Hysteresis value

So, guys, I've been researching a bit about the new option for the CPU Hotplug (for intelliplug only?), "Hysteresis Value". Here is a nice discussion about it, with input from Paul Reioux himself:

https://plus.google.com/app/basic/stream/z12md54rowqixpm0w225edernyneht15b04?cbp=1o7zq9bruhf4p&sview=27&cid=5&soc-app=115&soc-platform=1&aa=ac&spath=%2Fapp%2Fbasic%2F%2BPaulReioux%2Fposts&sparm=cbp%3D1lwnl61tzwfmv%26sview%3D27%26cid%3D5%26soc-app%3D115%26soc-platform%3D1%26spath%3D%2Fapp%2Fbasic%2Fstream%2Fz134c1ipsmfhjzgw404ccpd5eyjuhdr44ow0k#comment

It seems that a higher Hysteresis Value will result in slower response from the hotplug driver, i.e. the CPU cores will be activated slower, when there's load. If this is good or bad for battery, it depends, as sometimes bringing cores online and jumping to higher frequencies will allow tasks to finish early, thus saving battery... Appreciate if more people here can test how it behaves on the ZU.

when I flash DoomKernel v19, I can´t see my files in External SDcard, I have to back to v18... :(
[Sony Xperia Z Ultra] Jammol:
Your sdcard is exfat which currently isn't supported on v19.

Hey [MENTION=2784807]DooMLoRD[/MENTION] I'm not sure if this has been reported but wifi tethering acts like CM where you have to toggle it on and off a few times. Mine however would not allow anything to connect. Getting keymistach. I isolated it by returning to my backup I made before I flagged v19.
[Sony Xperia Z Ultra] DooMLoRD:
ya i am discussing it with the CM/AOSP devs [MENTION=2492127]Kali-[/MENTION] & [MENTION=359497]jerpelea[/MENTION] ... trying to find a fix... mostly its some configuration issue...
[Sony Xperia Z Ultra] Jammol:
Awesome. Dude what if you figure it out and it ends up fixing tethering on CM as well. Lol.
[Sony Xperia Z Ultra] :
I have used Pimped My Z1, FauxClock, just would like to know is there any other app which is both compatible and good with this kernel?

Thanks for sharing : )
[Sony Xperia Z Ultra] DooMLoRD:
ok good news... [MENTION=3332811]faux123[/MENTION] has sent me updated patches for intelli_plug! now we do not need to use custom wlan modules! and exFAT support will remain intact!

i think this is better solution than trying to find fixes for the issues in the last version of kernel...

i am doing some testing but will soon be releasing updated kernel with stock modules compatibility!

---------- Post added at 01:10 AM ---------- Previous post was at 01:07 AM ----------

One thing I've been willing to ask for some time: anyone noticed how when you select smartassv2 CPU governor, the first core is always at the max frequency?

When I'm in Faux Clock, first time I change to smartassv2, everything seems fine, the core slows down to 300 MHz. But it's just a matter of changing tabs in the app, or switching to another app, then it's stuck at 2.266 MHz. (Reporting this just in case someone wants to reproduce the issue; it's not related to this app.)
[Sony Xperia Z Ultra] blueether:
Have a look in my git ;) I think I i even did the merge for you (although it is way out of date now) https://github.com/BlueEther/android_kernel_sony_msm8974_DooMLorD/tree/DL_dt2w

I that section above I tried to mirror what was in the Sony code, just diff it. Not well written and I thing may not be needed at all. [MENTION=3223392]reaper61616[/MENTION] wrote it originally (then got upset ad removed it from git). He had removed the if()'s all together in that section i think. The dt2w branch is the import from is git, new_dt2w is my working branch.
[Sony Xperia Z Ultra] Lightbird:
so, i`ve tested the V20 Kernel and found just one little bug:

on the ZU the 5 GhZ W-Lan network looses power when you try to use it (means it just nearly turns off), 2.4 GhZ works fine.

that`s all i`ve found :good:
[Sony Xperia Z Ultra] zost:
Is there the third recovery (Philz) for Xperia Z Ultra, and is there a way to activate/use it. As you know, ZU has no camera button:)
[Sony Xperia Z Ultra] xPoiled:
Great...make the doubletap2wake possible in xzu doom..been dreaming about this for a long time.:)

Just a suggestion,maybe you can also ask alnikki25 (from the xz forum) to help you on dt2w for xzu.

(two heads are better than one,as they said it) lol

Thanks bro..
[Sony Xperia Z Ultra] DooMLoRD:
You can you my Xperia Reboot app... I am trying to configure the third recovery entry to the power button but for some odd reason it's not working...

For Z its a native implementation

Im Falling Love With This Kernel (Sorry For Bad English)
[Sony Xperia Z Ultra] shaolin95:
Has anyone experiences moments were the phone becomes laggy and wont come out of it unless you restart? Like changing governorns etc wont help. Right now I am just running Performance and it seems to avoid that so maybe it was one specific governor I used and it was not showing any thermal slowdowns when it was laggy btw.

Maybe some other settings I am missing?
[Sony Xperia Z Ultra] pemell:
No no don't run performance as your daily governor. It'll drain your battery as fast as Homer drinks beer. Try stock ondemand and don't undervolt.
[Sony Xperia Z Ultra] shaolin95:
Oh yeah, I am familiar with Performance and killing the battery :D

I will try onDemand again.

I see noop 512 and noop 128 under the I/O schdeuler settings in Faux123 kernel app.

Is that what you have too?
[Sony Xperia Z Ultra] bryanky5:
Something weird happened! I tried flashing v20 and it flashed fine on TWRP then i rebooted. Of course I expected it to reboot properly and went to the toilet but when i came back, the LED light was flashing red constantly (i had it plugged in) and of course this means it was bricked, won't turn on, red reset button didn't work etc

I fixed it by putting it into fastboot and flashed another kernel through flashtool

I'm not sure if I did something stupid or what but this NEVER happened to me before..hm

I'm getting multiple random reboots while using this kernel for some odd reason. I've had to go back to stock kernel for now. Has anyone else ran into this with this kernel and if so how did you did it?
[Sony Xperia Z Ultra] madsponge26:
Works flawlessly for me. No issues. Interactive +Noop.. Im in monx rom:D
[Sony Xperia Z Ultra] WildBit:
UI was getting some reboots when using Wheatley governor. Did some testing and for me I reverted to Interactive with noop scheduler and not only have the reboots stopped but I'm getting really good end user experience. So give it a go and btw I have all 4 cores running the same governor, that had a positive effect as well.
[Sony Xperia Z Ultra] DREWHAMM974:
Will try interactive and noop then. Always have used ondemand and deadline but alot of reboots. Also, what. Xposed modules are you using. Tried to many and kept getting system ui fc. Not sure what caused that as well. Just clean flashed Monx and v20, going to see how it does. So far an hour without a reboot. Better than before. *Knock on wood.
[Sony Xperia Z Ultra] :
i had been using Mokee ROM for awhile without any random reboots. Then came back with RomAur + DoomKernel v20. Poof! First random reboot when I updating apps in PlayStore! It's kernel default setting!
[Sony Xperia Z Ultra] gasland:
Download Links do not work.

Any new ones Please?

Ps:Random Reboots on V19 as well
[Sony Xperia Z Ultra] shaolin95:
no reboots for V20 on my end, just using a stock 757 rom no xposed or anything like that.
[Sony Xperia Z Ultra] DooMLoRD:
