Disable dt2w

Testing the kernel with the newest Carbon build (which is excellent, but will give proper feedback later in the respective thread). So far very good performance and didn't find any bugs, but will test more.

Just one thing: how can I disable the doubletap2wake? There's nothing in /sys anymore (searched for *dt*, *double*, *tap*, *wake*). I don't really care for this feature, since it's not 100% realiable, and I suspect it drains the battery a little faster. If it's impossible to disable at runtime... Can I ask for a version without this feature? :D

Thanks!
[Sony Xperia Z Ultra] blueether:
From the carbon thread:

or did I take that out to rewrite it??? I think I did...

Yes I removed almost all of what reaper61616 had written when they threw their toys out of the pram when someone used their GPL code within the rules of the copyright, I should just include it as it was/is available in the nexus kernels by showp1984.

I don't think it uses much power at all, my test device (broken sim reader) can have 20+ days uptime with it enabled
[Sony Xperia Z Ultra] dbolivar:
OK thanks, in fact since I couldn't turn it on and off, I can't tell for sure if it's really draining the battery. I just noticed a slightly higher consumption, but it can be anything kernel-related (governor, I/O scheduler etc.).

Just one thing that's still there: impossible to turn off the device, it just reboots. I don't recall if there is any workaround for it, is there?
[Sony Xperia Z Ultra] blueether:
I think it was fixed in the last Z1 release, but I merged in the 4.4.4 kernel before Androguide.fr had on the Z1 so I haven't picked up that fix. I should rebase to his release
[Sony Xperia Z Ultra] ShadowVlican:
working well with the latest Carbon ROM (as of this post)

no obvious issues that i've come across from my daily usage the past week

Sorry for the off-topic post, but I have to,

Anyone interested in GreatDevs Kernel Support for Z Ultra?

[KERNEL][CM-4.4.4] GreatDevs Kitkat V1 [ OC/UC | UV | F2Fs/exFAT | GOVs | IntelliV2 ]

Please let me know if so, I need some testers cuz I don't own the device :o

[Sony Xperia Z Ultra] :
I'm interested. I will also test.
[Sony Xperia Z Ultra] ch3mn3y:
+1 i like new things. Will this kernel support f2fs /data and have recovery with f2fs support?

If i,can i have small request: row i/o as i tried most possible set ups on pimped and nightmare on 2 first cores and pegasusq on two remaining + row on internal and vr on sd is the best (at least for me) <-- and im just missing row scheduler (however its possible that i didnt find it in ur thread)

You can flick it this way as well if you want.

I've not had much time of late to look at pimped. Did you get a new build booting on the Z1? I did post a build but didn't want to step on the orig dev's toes too much - I see it was only DL'd 118 times
[Sony Xperia Z Ultra] OmarEinea:
I built one for Z1 and sent a pm to some testers, and I'm trying to that for togari as well :)

also this kernel isn't just an updated pimped kernel, it is a mixture between to kernel's and has (and will have more) cherry-picked features from many kernel,

I'm intending to support it and add more features and stuff, so I'll appreciate whatever help I can get, so it'd be great if you can help :)

Omar.

For some reason my Carbon does not want to cooperate with this kernel, it just wouldn't go pass the Sony logo nor go into the recovery.

Had to flash the Carbon boot.img.
[Sony Xperia Z Ultra] Triflot:
Use the GreatDevs kernel instead; it's up-to-date!
[Sony Xperia Z Ultra] 341464:
Boot loop again!

EDIT: Well, this is weird, did a clean install, and boot looped for like 5 times, and then it booted fine- and then it didn't even finish the boot animation, there goes boot loop again.

I don't think that there has been any new kernel code that should make Pimped unstable, and if you have the same issue with greatdevs it might be a carbon issue.

I'll do a new build of pimped when I have time
[Sony Xperia Z Ultra] DarkSandmaN:
did anyone try this kernel with Pac-Man 4.4.4 rc-1? it have 3.4.0 cyanogenmod kernel by default. i am not so good at playing with phone systems i dont wanna bootloop or something :)
[Sony Xperia Z Ultra] ch3mn3y:
It should work aa its using cm kernel too. However u can make backup in cwm, which part will be kernels backup and if something wrong goes u will be able to restore kernel u,have now.

But as this kernel is based on cm one there should be no problems

Sent using C6833 - AICP/GreatDevs
[Sony Xperia Z Ultra] blueether:
the other way to go about it is to hotboot the boot.img, this has the advantage of not overwriting the original kermel and a reboot will bring you back to what you have now.

fastboot boot boot.img
[Sony Xperia Z Ultra] DarkSandmaN:
i appreciate what did u tell me there but i have no idea what i need to do with a hotboot the boot.img. i done something like that when i was unlocking bootloader but i dont know what i did i just followed one post from xda :) is is safe to try methode from post bifore yours with cwm backup?
[Sony Xperia Z Ultra] ch3mn3y:
Have u installed flashtool on your pc/mac? If yes start it, click thunder icon than choose fastboot and on right side of new window u will have hotboot option.

Connect your phone like u did when u were unlocking bootloader or flashing pac mans kernel

Blueether wanted u to use cmd or (dont know its name) mac terminal and flsh the kernel using command he wrote.

[Sony Xperia Z Ultra] DarkSandmaN:
so i need to do this https://www.youtube.com/watch?v=IXTzA7Qrrv4 and what if that kernel dont work how it is intended? can i undone flashing?
[Sony Xperia Z Ultra] blueether:
If the kernel doesn't work one of two things will happen if you have hotbooted it correctly:

1/ The kernel bootloops, when it restarts you will be back on you original kernal

2/ The kernel hangs, then you will have to hold the volume up key and the power button. This will shut down the ZU, then just start as normal and you will be back on the original kernel.
[Sony Xperia Z Ultra] DarkSandmaN:
Thanks guys i did hotbot kernel but it wont work. on one version my touchscreen dont work, on other phone cant join operater and tirth method it just stuck on kernel logo. ill stay on stock pac-man kernel for now,but tnx for help cheers

For those of you that want LCD colour management and voltage control the download the beta version of Pimp My Z1 from here:

http://xdaforums.com/showpost.php?p=51932959&postcount=163

I've not tested the voltage control, and if you do use caution as to high will cook your CPU and too low will cause reboots.

The second build of the kernel added 600 MHz to the GPU if you haven't seen it already

Don't know why the images arn't working in a browser, they seem fine in tapatalk LINK -> https://plus.google.com/u/0/+CharlesFryett/posts/BrpjAFrqzL6

Thanks for that, I saw your post after I got it ported, would have save a but of work but never mind.

If you want to set the second core turn off multi-core and set the CPU to what you want the second core to be, back to main menu (not sure if you have to do this or not), the back to CPU and turn on multi-core and set cores 1,3 and 4 as needed.

Can remember if I said why they wont work, but the ZU uses a different touch-screen than the Z1 family so different drivers, and we already have pen/pencil input anyway.

Yeah, governers and that won't take up much, if any ram. I may take out some of them if/when [MENTION=4752917]Androguide.fr[/MENTION] does a benchmark on them

Looking at the kernel it looks like f2fs is enabled in the kernel already, you just need the userspace tools/recovery that can read/write/format to f2fs.
[Sony Xperia Z Ultra] ch3mn3y:
Can not to thank u as u answered so many of my question :)

I tried ur solution for second core governor and will use it for the moment to see if it will work after some time

Ps. As multicore u mean power managment? Coz i dont see any other multicore options

Edit: i "played" some with the options and second governor is autochangeing when multicore power saving is enabled. If not it stays on "my" governor. Will check it

Edit2: After some more time i can say that doesnt help. Ill try to ask in original z1 thread

Edit3: i see u asked about this issue. However for me its little different as for all cores i have set nightmare, but when percore second.is always intellidemandx

Sorry, I meant per-core on the CPU tab. ie just treat all the cores as the same, then go back to per-core governors

Tried it and it doesnt help. However I found out that last night i had per core (nightmare/nightmare(intellidemandx)/powersave/powersave) and lost 13% and today on allcore nigtmare lost 0% so its better

[Sony Xperia Z Ultra] E90 Commie:
Is it possible to use this kernel with the GPe ROM?
[Sony Xperia Z Ultra] dbolivar:
Be very careful with fast charge. If you charge your phone via the USB port of your computer, tweak fast charge's settings to 500 mA MAX current, otherwise you may fry the USB port. Even with the standard charger, adjust the settings to its max rated current. Also, it is good to enable battery thermal throttle, but I don't know if Pimp My Z1 support it, and if Pimped Kernel has it. If they don't, monitor the battery temperature closely during the charge.

My opinion: don't use it unless you truly need a fast charge for something urgent. The risks and (possibly) reduced battery life are not worth it.
[Sony Xperia Z Ultra] ch3mn3y:
Thank. I dont need it I jsut wanted to now coz maybe i will need it. Thermal throttle is supported by pimp my,z1 (and i have it enabled). And if somwthing happen and I will need it I will use my tablet charger, which has 2000mah out, so to "be safe" i should set 2000, right?

[Sony Xperia Z Ultra] blueether:
I doubt that it will boot the GPe ROM, but if you know how to get your self out of a hole then by all means try it...

I doubt it will work because of the caf extensions that this kernel is using
[Sony Xperia Z Ultra] dbolivar:
I wouldn't use a charger with a current higher than the standard one, because the battery may not be designed to handle that excess current and may heat a lot, or even blow up. Usually there are voltage and current regulation circuits to avoid something bad to happen, but I wouldn't risk it.
[Sony Xperia Z Ultra] blueether:
I think [MENTION=4642591]hamdogg[/MENTION] did some testing and the zu peaked at 1800mA. I don't think I would push it too far, the zu will pull 1300-1400 off my wall charger

[Sony Xperia Z Ultra] wooki:
Just had to smile, my 2 year old phone (which was shipped with a 5V/1A charger) is being charged at the same 5v/2.1a charger than the XZU and the battery didn't blow up once.

Want to know the secret? As long as the voltage is correct (5V) you can use any charger because the device will limit the max amount.

Hope I could help a bit :)

[Sony Xperia Z Ultra] blueether:
We aren't just talking about chargers, but forcing a higher rate of charge with the kernel.
[Sony Xperia Z Ultra] ch3mn3y:
Exactly.

So if i ever would like to use fast charge the safest option is to use charger i got with phone (phablet :) ) and set options to 1500. Good that i can live without it coz there is too much to think and be afraid that something can happen

[Sony Xperia Z Ultra] ch3mn3y:
I found one strange thing (for me). Clokworkmod saved backup in /data/media/clockworkmod instead of /data/media/0/clockworkmod. Why? I thought that it can make it only on /sdcard (which is /0/ right?) or /sdcard1.

I fohnd it coz i was looking for lost ~2gb of memory

Next: i cant use ma sdcard. On v2 it was working, on v3 i got mounting error when trying to make backu on it or use /sdcard1 as installation path

Sent using C6833 - Carbon KitKat/Pimped Z1 Kernel
[Sony Xperia Z Ultra] dbolivar:
Just tested the kernel (without DT2W) with my personal build of Liquid Smooth. Working great, good job! Right after flashing it was a little choppy, don't know if it was because of the kernel settings or the ROM, which was freshly installed. But after tweaking some kernel parameters, it is now very, very smooth. I also did a benchmark with Antutu, and when setting CPU and GPU to "performance", it outperforms almost every score of the stock ZU listed in the app.

Battery life is inconclusive so far. It's not draining fast, but perhaps it's a bit worse than stock + stamina + DooMKernel. Could be my kernel settings, the abscence of a battery saver, or the ROM itself. I'm testing some battery savers right now, to mimic what Stamina does (disable sync for apps when battery off).

As for issues, zero so far. The list of features are huge, so I'm definitely keeping this kernel when not using a stock ROM. Thanks!
[Sony Xperia Z Ultra] golfinggino:
Is there any differences between the dt2w version and the 4/24 kernel besides dt2w ? I want the latest version but the double tap doesn't work very good on my ultra - can it be disabled any way ?
[Sony Xperia Z Ultra] blueether:
I haven't touched cwm so this will have to be a bug in their code I think, I'll test these two out now...

sdcard mounted fine, will test external backup...

Read and backed up fine to external 8gb card here.

The nandroid I did from either v2 or from carbon is at /sdcard/clockworkmod/backup, just did a backup using v2 and it went to the same dir.

Battery seems hit and miss for me, cant quite find the culprit, one was cm's lockclock weather, disabled that and had much fewer wakelocks and cpu time. Yesterday I averaged 2.7%/hour with light use and poor cell reception for about 8 hours of the day, so not too bad I guess.

I could turn up the power to the touchscreen when asleep, and it will work first time every time, but I'm not sure what effect it would have on the battery life...
[Sony Xperia Z Ultra] golfinggino:
What is everyone using for the colour calibration settings ?
[Sony Xperia Z Ultra] blueether:
I'm just using default at the moment, but I think I was using about R: 245 G:245 B:255

I only difference is d2tw and PM8941_flash, that I accidently included (code for camera flash).

You can disable it with this code from a terminal emulator on the ZU:

su -c "echo 0 > /sys/android_dt2w/dt2w_active"

F2FS

Since now we have Pimped Kernel with F2FS, and more and more ROMs are including support for it... Anyone brave enough to try it? :) Here are some nice benchmarks done by Androguide.fr.
[Sony Xperia Z Ultra] blueether:
The main problem at the moment will be f2fs support in the recoveries on the ZU won't it?
[Sony Xperia Z Ultra] blueether:
Thanks for letting us know that it works, what date/build did you test on?
[Sony Xperia Z Ultra] dbolivar:
I've seen many ROMs include support for it, for example CM11:

F2FS tools

Recovery

I remember seeing similar commits for other ROMs too. Now, if this "USE_F2FS" is defined on the makefiles I don't know, neither if this is all we need to format something as F2FS.

And I think Androguide.fr has released a version of Pimped Kernel with F2FS support enabled by default in both vold and recovery, am I right?

EDIT: have been searching here on XDA. It seems that for it to work you need:

1) A ROM with support, specially because of the f2fs-tools.

2) A recovery with support.

3) The kernel, obviously.

4) A special zip file to format the partitions with F2FS, because as far as I understood, the recovery can identify and mount filesystems formatted with F2FS, but not format them. I think the same can be accomplished by entering ADB when on recovery (if it supports adb mode).

See for example these instructions for the Nexus 7.

Is this Kernel ART compatible? Just asking because I was using ART until flashing this kernel and I noticed it had changed back to Dalvik.
