Special reason that dt2w isn't working? Relatively new patches in PAC4.4 and Carbon proof it's possible on this device.
[Sony Xperia Z Ultra] blueether:
The DT2W is quite different in the Z1 to our ultra. There is no reason that it cant be ported into this rom though.
[MENTION=4972043]dbolivar[/MENTION] see github.com/reaper61616 or github.com/BlueEther and patch max1187x.c.
[Sony Xperia Z Ultra] iBuzman:
I'd hope any development of dt2w functionality is in a new / additional version instead of the "stock" DoomKernel... I don't want to have to drop the only tweaked sony kernel available :)
[Sony Xperia Z Ultra] dbolivar:
DT2W

This is the same thing I said about the SlimKat kernel I ported, when people requested additional features: I won't do it, at least not for these ported kernels, because in this case they won't be "SlimKat Kernel" or "DooMKernel" anymore, but something else, and I want them to remain as close as possible to the originals, differing only on what is needed for them to work in the ZU. If in the future I develop my own kernel, then I'll gladly consider all your suggestions. :)
[Sony Xperia Z Ultra] badboy3_mm:
Why do you didnt include cpu overclock on this kernel, the z1 one include gpu and cpu oc but that part ou your port isnt. Is it correct?

Enviado do meu C6833 através de Tapatalk
[Sony Xperia Z Ultra] venorme:
The thing is that original kernel you ported does support DTW.

I am sure I will enjoy kernel if it fixes power drain
[Sony Xperia Z Ultra] dbolivar:
As I said in the first post, I haven't added, removed or changed any features. AFAIK CPU and GPU OC were disabled in the Z1 kernel due to some incompatibilities, at least on v08 and v09, and I'm not sure if they are back in v11. I'll investigate, as the CPU and GPU are the same in the ZU and Z1, so it should work if it is already working in the Z1. Meanwhile you can check with someone who has a Z1 if these features work using v11.
[Sony Xperia Z Ultra] LordManhattan:
Yup. I don't "get it"either. People want a way to play Russian roulette and see who can wake up their phones up the most and take a picture of their junk and send it to the cops. What's the point of a lockscreen (notice the "lock" part) if you can't be sure that it'll still be locked when you grab for that pack of gum you have in that pocket? What if I'm wearing a pair of pants that's pretty thin? Will my thigh wake up the phone?

I'm perfectly capable of pressing a button once and put my finger on the screen, thank you. I swear we're heading towards some obese Wall-E future when I hear about stuff like this. People can't even press a button anymore.

[Sony Xperia Z Ultra] dbolivar:
Faux Sound is there in the kernel since some versions ago... Or did you mean support in Faux Clock app? In this case you really have to use a different app, like Trickster Kernel Mod or Faux Sound app. I noticed the volume levels are by default somewhat tweaked: PowerAmp is cranked to the max (6), the rest is 0. If this is the best setting I don't know. Btw, check if the levels stick after changing and playing / stopping music, because there was a bug before where the levels would go crazy in this scenario (should be fixed now). In my tests it did change after playing / stopping music, but it might be because I'm using another sound mod (ViPER4Android).

[Sony Xperia Z Ultra] Coolpsi:
Hi guys! After using it for 24 hours, everything seems to work ok. I had no reboot issues and, the battery endurance seems ok (after 24 hours of low usage in stamina mode - 2 hours of screen on - I still have 64% of battery). Many thanks to "DoomLord" and "dbolivar". Cheers! :good:
[Sony Xperia Z Ultra] dbolivar:
Thanks for the feedbacks, guys. I'm also getting impressive battery life, specially after enabling this:

msm_sleeper driver

It drains only about 2% overnight, with everything on (wifi, sync etc.). And no reboots so far, so it may be something else besides the kernel for those who are experiencing this; if it happens again, report in which scenario it happened, which customizations you have, special apps and mods like Xposed modules etc.
[Sony Xperia Z Ultra] shine2007:

can you please give a little tutorial how to enable this?

[Sony Xperia Z Ultra] S.D.Richards:
System modification, thus obviously you need to do this as root.
[Sony Xperia Z Ultra] shine2007:
im sorry ..im not understand

i already Rooted,,

you mean..i need to modif using Root explorer?
[Sony Xperia Z Ultra] S.D.Richards:
You need to issue the command under the root account. Just the fact that you rooted the phone doesn't mean that everything runs under the root-context. Open the shell and type 'whoami'. If it doesn't say root, you need to switch to root first by giving 'su -' and then issue the 'echo 1 >...' command.

Be aware that this command doesn't survive a reboot, so you might want to read up on init-scripts.
[Sony Xperia Z Ultra] blueether:
Another option is to use sudo so the command becomes:

sudo echo 1 > /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max

There id also the slimkat kernel that should boot CM11 as will the Carbon kernels. I have also just ported Z1's pimped kernel and if it's stable today I'll post it publicly. It should boot new CM11/Slim/Carbon/FXP/etc so stay tuned.
[Sony Xperia Z Ultra] S.D.Richards:
Nope, sudo doesn't work here, because of the '>' redirection.

[Sony Xperia Z Ultra] Coolpsi:
Can someone tell me if it is possible to set the max. frequency of the phone to 2419 MHz and, if so how to do it? Do note that I have tried to do it with SetCPU and ROM Toolbox (selecting the 2419 MHz and selecting the "apply on boot" option), but after rebooting the phone the max. frequency is still 2265MHz. Many thanks in advance.
[Sony Xperia Z Ultra] blueether:
From the reading I have done while porting the Pimped kernel I think the max freq comes down the binning of the CPU.
[Sony Xperia Z Ultra] Coolpsi:
Thank you for your reply Charles, however I am not sure I understood your answer, because it seems that I don't fully understand the "binning" meaning... :-\

How can i enable dt2w?
[Sony Xperia Z Ultra] ch3mn3y:
If im not wrong since 11r2 dt2w is disabled, coz it was only partly working on our device. Im not sure, but it probably still doesnt work so its not enabled

Sent using C6833 - Carbon KitKat/Pimped Z1 Kernel
[Sony Xperia Z Ultra] blueether:
DT2W never worked in this kernel on the ZU, and it has also been removed from the Z1 because of battery drain, it keeps a wake lock.
[Sony Xperia Z Ultra] xPoiled:
Thanks for the reply..

that is odd considering that my previously owned XZ has this dt2w and it is working flawlessly.

hope that some of our devs can make this work without such battery drain to avoid wearing out of our power button.

you could ask [MENTION=4972043]dbolivar[/MENTION] for a version with dt2w built in, he has the code, but as I said it can take upto 4 or 5 attempts to get to work sometimes so I found it more annoying than a usable function.

FYI Version 17 came out for the Z1. We should see one soon for the Z ultra :)
[Sony Xperia Z Ultra] dbolivar:
Don't worry guys, I'll upload this version probably today or tomorrow if it's proven stable. There's a new MPDecision driver and some users are reporting issues there in the Z1 forum. Since this is basically the only change, you don't lose anything sticking to v16 meanwhile.
[Sony Xperia Z Ultra] martin132014:
Can i ask does doomkernel suppprt voltage control..cause i have cpu tuner and i can't find voltage control on it....
[Sony Xperia Z Ultra] dbolivar:
v17 released

v17 for the ZU has been released! The main changes are:

New MPDecision driver which can be enabled by manually renaming /system/bin/mpdecision to /system/bin/mpdecision.bak and rebooting once. Follow the instructions to configure it here.

Updated Linaro toolchain to version 4.9.1.

Added my special compiler optimization flags which I came up after a lot of research, should make things faster.

Note that this new MPDecision driver can be buggy or cause reduced performance / lags, as reported in the Z1 forums. Test and report here how it goes. It can be fine tuned in the link above, perhaps this is needed to make it perform optimally.
[Sony Xperia Z Ultra] pemell:
The custom mp decision is a no go. Very very bad for the overall performance. I'd recommend to disable it.
[Sony Xperia Z Ultra] dbolivar:
Totally agree, just tested and didn't like it. Back to v16.
[Sony Xperia Z Ultra] iBuzman:
Running/Testing 17, haven't played with mp decision config settings yet (but have turned it on via fauxclock) will report back any findings of interest :)

(saying that, everything always seems to work fine for me and I am never sure how my performance would have been if I hadn't enabled whatever I was testing hehe)

Update: Antutu scores on 17 about half those I get on 16.. (yes, I know benchmarks are useless lol)
[Sony Xperia Z Ultra] bryanky5:
Yeah just tested v17 and 5minutes in started lagging like crazy, went back to v16 for now.
[Sony Xperia Z Ultra] arceles:
No problems here neither on v16 nor 17
[Sony Xperia Z Ultra] pemell:
[MENTION=4972043]dbolivar[/MENTION] did some reading and made some more testing and I'm reverting my above statement. The custom mpdecision is working for me, and it clearly saves me battery but still containing performance. No lag at all.

What I did: installed the kernel but didn't touch anything else but enabling the mpdecision.

Thing is the mpdecision only works with ondemand.

I love it! Before my CPU would jump up and down. Now it settles at 300 and stays there when not touching the device (with screen on).

I recommend using it but be careful with other tweaks as it might make your device lag.
[Sony Xperia Z Ultra] prbassplayer:
I haven't looked at source, but showp's Mpdecision should work fine with any governor, if boost pulse is disabled it works better with interactive or ondemand (as long as it has boost pulse). At least my experience on mako. But you need to disable stock Mpdecision (if not at least with trickster app) else it will conflict and cause some funkyness
[Sony Xperia Z Ultra] :
on v17 it's very laggy. already disabled stock mpdecision (renamed to bak) and governor=ondemand. still laggy. quadrant score only 10k
[Sony Xperia Z Ultra] pemell:
[MENTION=4972043]dbolivar[/MENTION] and everyone else

I found the issue why the custom mpdecision lags on our device. Core 0 will stay online but Core 1-3 won't be hotplugged. Thus the device will constantly run on one core.
[Sony Xperia Z Ultra] prbassplayer:
Did you disable the stock mpdecision?
[Sony Xperia Z Ultra] pemell:
Yeah, it's definitely disabled.

And I tried with it enabled too but the msm_mpdecision will kick in at some point and unplug core 1-3.

The only good way to use the v17 of this kernel is to stay on stock mpdecision. And by doing that you have to disable msm_mpdecision at boot.

http://xdaforums.com/showpost.php?p=52596664&postcount=1582
[Sony Xperia Z Ultra] prbassplayer:
A interesting thing to test is neutering stock mpdecision from the root (removing the blob and modifying ramdisk), but that's something [MENTION=4972043]dbolivar[/MENTION] needs to do. Showp's install script does it on installation. Hammerhead and mako on slim does it though init.d scripts.
[Sony Xperia Z Ultra] pemell:
Thanks man. I've forward the idea to DooMLoRD too.
[Sony Xperia Z Ultra] pemell:
finally confirmed by doomlord: http://xdaforums.com/showpost.php?p=52599021&postcount=1598

I will keep on using v17 because of [MENTION=4972043]dbolivar[/MENTION] and: "Added my special compiler optimization flags which I came up after a lot of research, should make things faster."

I really like it. If you guys want to stay remember to re-enable stock mpdecision and disable msm_mpdecision at boot.
[Sony Xperia Z Ultra] dbolivar:
v18 released

First of all, thank you all for testing v17 and reporting the issues, it helped not only the ZU community but also the Z1!

For v18, DooMLoRD basically reverted the changes made for v17 regarding the new MPDecision. As he did for the Z1, I'm also including the original /system/bin/mpdecision file, reverting any renaming people may have done when testing v17. The rest, like the new Linaro toolchain and compiler optimizations, are there, and will continue for future versions.

Enjoy!
[Sony Xperia Z Ultra] DooMLoRD:
Hi all!

so some users are willing to donate a Sony Z Ultra (GPe) to me for development... basically since the price was recently knocked down to 449 USD its become more affordable :P

http://xdaforums.com/showthread.php?t=2746437

users have already pledged close to 260 USD so around 190 USD left...

if you guys want me to have this device and directly support it (kernels, recoveries, rooting kits, porting ROMs GPe to non-GPe & vice versa, leaks ;) ) head over to that thread and pledge your donations!

[Sony Xperia Z Ultra] pemell:
Don't like utilities, I do everything manually.

[Sony Xperia Z Ultra] mr.joshuanice:

[Sony Xperia Z Ultra] WildBit:
Can you share how and what files to modify? You have to use at least 2 different utilities to OC CPU an:good:PU, Manually sounds much much better

Thanks in advance
[Sony Xperia Z Ultra] pemell:
Uh, there's so many files. Let's start with the cpu overclocking:

1. You have to increase the cap on the cpu freq by modding the msm_cpufreq_limit.

2. Then you can increase the frequency on the files scaling_max_freq

My code, inserted in set_governor.sh looks like this:

echo 2419200 > /sys/kernel/msm_cpufreq_limit/cpufreq_limit
echo 2419200 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 2419200 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
echo 2419200 > /sys/devices/system/cpu/cpu2/cpufreq/scaling_max_freq
echo 2419200 > /sys/devices/system/cpu/cpu3/cpufreq/scaling_max_freq

Just wondering why do you recommend turning Dynamic Fsync off? Noticed any reduced performance, or worst battery life? I've never made serious benchmarks with it on and off, but was keeping it on because I thought it was good for battery life...
[Sony Xperia Z Ultra] pemell:
Because you might get data loss if the system crashes. I actually don't see any good reason to keep it on, it's not good for neither battery life or performance.
[Sony Xperia Z Ultra] WildBit:
Agree, after some tweaking with this v18 kernel I reached the highest score ever. Dont know about the benchmarks but certainly the phone feels great to use :)

I had to use a mixture of scripts and utility (system tuner) to achieve the result

[Sony Xperia Z Ultra] pemell:
I've found another critical issue with the kernel.

On the default GPU governor "msm-adreno-tz" it will stay on max freq.

And that's not all.

simple_ondemand is the only governor where the freq scales.
