While most people care about juice I don't. I've got a powerbank always with me so I always have a power. This so called "feature" makes dark image worse while outside when I want to max out my brightness, then I simply can't. Most apps I'm using are black & white. Even WhatsApp is black and text is white, but when someone sends me an image which is relatively white enough to tell cabc to max out brightness, then I can see everything in strong sunlight.

This build will be of this kernel? If yes, shouldn't we ask dev if we can modify it?
[Sony Xperia Z Ultra] Tommy-Geenexus:
Nope, it'll be in my Zombie Kernel.

[MENTION=4800636]OmarEinea[/MENTION], what does the dynamic fps in /sys/devices/virtual/graphics/fb0/dynamic_fps ?
[Sony Xperia Z Ultra] Tommy-Geenexus:
it's a dynamic flex render technologie, which aims at decreasing power usage while meeting the frame rate requirements (keeping up fps).

Somehow when I use Wheatly on this kernel, it keeps giving reboots for different apps. Anyone knows any ideal settings for the Wheatley governor?
[Sony Xperia Z Ultra] halifage:
I had to give up this kernel because it kept rebooting when playing online chess (never happened before with any rom).

Is there any "safe/stable" configuration (I/O scheduler, Cpu, Gpu, etc.) that will give us the best of this kernel without the random reboots?

Also, how exactly should I flash this kernel? straight after a clean install or just wipe cache and dalvik then flash?

Thanks

This is a great kernel. Fast and smooth, easy on the battery too. Thanks!

For some reason DT2W seems to be sometime working and sometimes not. Certain times I have to tap multiple time to get the screen on. Could it be a screen issue or some power management issue?

Seems like DT2W issue, at least for me, cause screen to be totally unable to turn on and need a force reboot. Not very common but does happen.

One last question, is the Intelliplug eco mode working on this kernel? I tried to enable it in Pimp my Z1 but it cannot stay switched on.
[Sony Xperia Z Ultra] alia5:
Any1 has a proper UV-Table?

On Liquidsmooth + this kernel it shows 1350mV for all frequencies

Maybe it's s bug related to Liquidsmooth, go ask its dev to fix it xD :p

(will see what I can do)

[Sony Xperia Z Ultra] :
I assume you were using Pimp My Z1 app? This is something that happens because it's outdated (the voltage table is not correctly recognized by the app)

I suggest using another app :)
[Sony Xperia Z Ultra] alia5:
Nevermind... Installed PimpMyZ1 app... Voltage control crashed the device, not the app... after a reboot it was fine... strangely enough

Edit:

Pimp my Z1 showed 500mV...

did i just brick my phone? i installed Carbon KitKat - Togari and then this kernal over it , now my phone has a blank screen and wont boot up..
[Sony Xperia Z Ultra] blueether:
did you unlock the bootloader? (and have a TA backup?)

Do you have a nandroid of before installing carbon or this kernel?

The way to recover should be this:

Extract the boot.img from the Carbon zip and save some where

Start flashtool (or use adb/fastboot)

Connect to the PC:

Power off the ZU

Hold the vol. up key and the power button

Keep holding the vol up key

(the ZU should enter fastboot - blue LED and blank screen)

If using flashtool:

Select the flash icon

Select fastboot

select the boot.img from above

If using adb/fastboot commands:

Run the command "fastboot flash boot <path_to_boot.img>" from terminal/consle/command-line

Doesnt get any sods on caebon, however im using 5/10 version, so maybe its newer aosp/cm bug?

Sent using C6833 - Carbon KitKat/GreatDevs
[Sony Xperia Z Ultra] Triflot:
A few people in the LS thread are saying the SODs could be due to DT2W. I don't know if that's true, but I can say that I'm running LS with GreatDevs kernel with DT2W disabled in both, and haven't had any SODs in weeks. Interactive + row + Dynamic fsync.
[Sony Xperia Z Ultra] KaBooMa:
I am running GreatDevs with AICP and seem to also be getting the lockup issue...Sometimes within 3 minutes of a reboot. It just kinda happens whenever it wants...You lock it or it locks from time and then when you double tap it doesn't open again :P Same if you hit the power button. Kinda a bummer I really like the dt2w feature. Hopefully something can be figured out.
[Sony Xperia Z Ultra] blueether:
It could be the IRC interrupts, I've never liked the look of how it was done in the initial release but I'm not a good enough coder to look at that lower level of code

It dosen't seem to effect pimped, only the newer kernels? I think I remember seeing a commit for interrupts lately?
[Sony Xperia Z Ultra] :
Pimped + Carbon gave me a bunch of SODs when I was running it.

The SODs seem to mostly happen when I try tapping to wake. Sometimes multiple taps wake the device, sometimes multiple taps give it an SOD.

Barely does just two taps wake the device.
[Sony Xperia Z Ultra] blueether:
odd.

The two taps

have

to be in the same spot, very little room for error.
[Sony Xperia Z Ultra] :
Yeah, I tap with precision.

But what's important is that SODs seem to only happen after an attempted double tap to wake.

Edit: Actually, I take it back that DT2W barely works. I forgot that it works well. I just stopped using because I didn't want too many SODs.

On the occasion that DT2W doesn't work on the first two taps, usually the device goes into SOD. It happens maybe once every 2-3 days if using DT2W exclusively (Not using the power button).
[Sony Xperia Z Ultra] OmarEinea:
Wohoooh!,,

GDv2 is half way here, and here are the main already included stuff:

Kernel Linux version updated 3.4.5 -> 3.4.12

ExFat Updated v1.2.7 -> v1.2.9

Include TWRP v2.8.

2

.0

A lot of commits cherry-piked from faux123's kernel

And for the things that still need to be done:

Start providing Full boot.img (flashable through flashtool) along side with the usual only flashable zip

Update Intellidemand Gov 5.0 -> 5.5

Grab some more cherry-picks

Update kernel logo

Maybe some other things that might come in mind;)

[Sony Xperia Z Ultra] ch3mn3y:
not asking for ota or anything, but will u support lollipop in the future?

And what features gives us 3.4.12 kernel? Is there any changelog with most important changes of linux kernel?
[Sony Xperia Z Ultra] jnx_r:
some queries/issues?

I would like to add something mate. If you can find the time, please do some real world testing, like maybe installing about ~100 apps of different kind or nature and using them for a while under various governors to uncover any issues which may exist. I had a few random reboots when I was using this kernel on CandyKat and on SlimRom. This is the one released on 8th Nov.

-

CPU doesn't scale to anything above 2.26Ghz even though the OC steps are there till 2.73Ghz. It does underclock very well though, and I've faced no issues with undeclocking it to 268Mhz. I'm new here [just bought an android device last Saturday after a really long time, my last device was the Xperia X10], so I couldn't figure out why. Do we need any particular program especially for this kernel to set the cpu freq above 2.26Ghz? What am I missing here? Also could you recommend any good app for CPU control and GPU control? I was using Pimp my Z1 app, but I noticed that when you changed the kernel values for CPU freq, the CPU had a tendency to get stuck at 2.26ghz until I reboot. I use an xposed module to show me CPU temp and Freq on status bar at all times. So I stopped using Pimp my Z1. But then Pimp my Z1 is one of the few apps which let us set the GPU freq along with per core governor. Are there any other apps where I can use per code CPU governor and set the GPU freq? Also even in GPU, the scaling is limited to 533Mhz, though it says its upper limit is 600Mhz in CPU-Z. Is there any special app for GPU scaling/OC too?

-

Also regarding the random reboots, once the system rebooted and kinda wiped out 6 apps and their appdata from a total of ~150+ user apps. The data from the other apps were reverted back to random dates. Some of them had their data intact while others were restored to their original state. The phone took much longer to accomplish this particular random boot. I was using interactive governor with freq set to 226-2265Mhz.

-

Also can someone recommend a governor which can give good performance under load, with the Temperature not crossing the 55-60C range even under extended use? I tried the some of the governors other than interactive, but I had to revert back to interactive, since some of them kept giving me reboots.
[Sony Xperia Z Ultra] blueether:
About the max of 2.26Ghz and 533 Mhz. I believe it is all to do with the binning of the SoC that the ZU has. The Z1 has better max frequency even though it is the 'same' chips as they had different chip bins.
[Sony Xperia Z Ultra] aerzjee:
For me it works very well. Even the 600mhz on GPU. I'm using intellidemand, with normal usage without any gaming it lasts for ~16h. With gaming it's about 6h. I'm on PA4.6 BETA2. The only problem is 2.7ghz. It simply doesn't work :P. When it goes to that freq, phone just restarts.
[Sony Xperia Z Ultra] jnx_r:
RE:

Does it have anything to do with the base firmware? I'm on .118

Which app are you using for GPU & CPU scaling?

Also do you monitor CPU temperatures? Mine goes upt 50 °C during normal usage like taking backup on titanium backup and other stuff. But when I'm playing games, it touches 60 very often at which point you can feel the heat. I'm using CPU temp on status bar Xposed mod to monitor CPU heat tendencies. I was also using CPU freq in statusbar Xposed mod but its not possible to monitor the freq of all the cores, so its just a round about value when it comes to CPU freq. Hence I disabled it.
[Sony Xperia Z Ultra] aerzjee:
As You can see on screenshot, on normal usage it's ~40°C. I'm using KTMonitor to watch freqs, and trickstermod to watch temps. In heavy gaming and streaming to my Samsung TV + PS3 gamepad it gets to almost 70°C.
[Sony Xperia Z Ultra] jnx_r:
Not good mate, the CPU itself may not get damaged but there may be other components nearby which do not have good thermal thresholds.

I try to keep it below 60 but even simple games make it past 60°C. I was playing plants vs Zombies 2 and it went to 65 with stock governor of this kernel, after which it throttled down to 960Mhz max frequency.

Is there any governor which gives decent performance under 60°C, without thermal throttling? It is very annoying after the frame rated drop to unplayable levels and the entire phone starts lagging everywhere.

-

Also which app are you using to set the CPU freq?
[Sony Xperia Z Ultra] aerzjee:
[MENTION=6172457]jenxrj[/MENTION] , when gaming on phone itself it doesn't even reach 60°C. I'm using intellidemand, it's not throttling because it doesn't even go past 1.7GHz barrier.
[Sony Xperia Z Ultra] slipknat:
how install this kernel ? i cant see boot.img in latest version
[Sony Xperia Z Ultra] OmarEinea:
Next builds will probably have boot.img inside them,

but for latest version and the ones before it you can only install them by flashing the zip through recovery.

Regards,

Omar.
[Sony Xperia Z Ultra] ch3mn3y:
I was thinking about that ur kwrnel is "building" itself from other kernels and if i will flash ie doomkernel and than yours will i have working aosp kernel with cwm+twrp+philz or woeking stock kernel (as dooms is stock one) or it wont even boot?

Sent using C6833 - AICP/GreatDevs
[Sony Xperia Z Ultra] OmarEinea:
Well that's kinda correct, but the only thing that your device might not boot after doing that is because of the incompatibility between doomkernel's ramdisk (which is stock based) and the AOSP ROM,

so I hope you luck when you try doing it :p

Regards,

Omar.
[Sony Xperia Z Ultra] ch3mn3y:
I would try but am fraid of bricking as its playing with kernel

Sent using C6833 - AICP/GreatDevs
[Sony Xperia Z Ultra] OmarEinea:
Nah nothing will be broken as long as long as you have flashtool and you can overwrite the kernel though it ;)

though still, do it on your own risk xD :p

Regards,

[Sony Xperia Z Ultra] slipknat:
are you can make kernel more battery saver ?
[Sony Xperia Z Ultra] jnx_r:
If you flash only Doom kernel[or most other stock kernels] on an ASOP rom, it won't boot.

-

Now to answer your question,

If you flash GreatDevs on top of Doomkernel, I don't think it will boot. Don't know the modifications Greatdevs makes to the Ramdisk while applying the kernel, so not exactly sure how things will play out.

EDIT:

I tried things out to see how things would play out. Anyways here it is:

If you flash GreatDevs on top of Doom kernel on an AOSP rom, then the device will NOT boot. The recovery[I was on TWRP] doesn't flash GreatDevs kernel after it has just finished flashing Doom Kernel. I tried rebooting but the result was the same. The recovery would get stuck in between flashing Greatdevs. Also Philz/CWM touch recovery is not enabled, so you have only option to go to TWRP with volume down button. But as I said before, it gets stuck when flashing GreatDevs.

-

Anyways, I fail to see why you would need two recoveries on a phone. One of them should be enough for anyone's needs.
[Sony Xperia Z Ultra] jnx_r:
It not only did not boot, it also screwed up my IMEI no. which was a pain to bring back.

I could not get it back using simple means, ie simply flashing another kernel or the custom rom's kernel and the modem files for 6833 did not fix it. I had to reinstall stock firmware and then restore everything.
[Sony Xperia Z Ultra] OmarEinea:
Well that's why we use "do it on your own risk" :p

although I'm sorry to hear your experience and I'll be more careful next times :angel:

Also thanks for sharing these information :)

Omar.

Hi, i have this intermittent Black Screen Of Death when i tried to Tap2wake the device.

It happen very often if i ON the MP Decision & Multicore power saving....

It still happen mayb once in 2 days...

Z Ultra Candykat v1.6.2 with GreatDev GreatDevs-Kernel-V1_2014-11-08_togari...

Please advice....
[Sony Xperia Z Ultra] jnx_r:
I think you should include a recovery in all your kernels hence forth. It makes things easier. Also a boot.img will be really helpful too. I wouldn't have to rely on the rom's stock kernel everytime something goes aloof.

Tap2Wake works perfectly. I don't think the issue is with the TAP2Wake thing, since I've tested this kernel for a whole week with the same ROM you are on right now, and AFAIK the TAP2Wake is the last thing that could cause a SOD.

The issue maybe with the CPU profile you are using it with. Not everything will work as you expect it to, sometimes we need to work around things.
[Sony Xperia Z Ultra] Tommy-Geenexus:
It's tap2wake.

The current implementation isn't reliable, and i'm currently trying to get it working outside the display driver which is a pain honestly.
[Sony Xperia Z Ultra] OmarEinea:
A Little Announcement!

Due to the circumstances I'm going through right now (computer problem, lollipop development, final exams after a month!)

and due to switching to lollipop ROMs (in the next few weeks), this kernel will be useless as long as it's based on CM's KK sources!

I decided to delay GDv2 for a little while in order to provide you a new build that is:

Based On Sony's AOSP sources

Freshly well written code from scratch

Includes all GDv2 changes I talked about

And will try to do what you guys ask for ;)

And to make it easier to me, I'll put a list of everything that I'm probably gonna be including in the kernel in the second post,

so I'll read your suggestions and add them to the list if it's reasonable to include them in the kernel :)

I'm sorry for the lack of the updates, but I'll dedicate my time to lollipop ROMs development for a while,

and I'll be back to developing this kernel afterwards :fingers-crossed:

what do you think guys?

Regards,

Omar.
[Sony Xperia Z Ultra] Tommy-Geenexus:
Np mate, i'll push out some kernels meanwhile.

Feature request: bidirectional s2s (can be found on my git)
[Sony Xperia Z Ultra] jnx_r:
What do you mean when you say it isn't reliable, could you be a bit more specific? Are there any symptoms/issues I need to be aware of?
[Sony Xperia Z Ultra] Tommy-Geenexus:
yes.

1. your panel never actually sleeps

2. touch detection isn't properly working

3. because it lacks of a proper implementation

So it should be removed and re-worked.
[Sony Xperia Z Ultra] jnx_r:
I guess it must affect battery life too.

What is the best app to control the settings for this kernel?
[Sony Xperia Z Ultra] ch3mn3y:
I think pimp my z1 if u dont want to change voltages. To do it u need other app

Sent using C6833 - AICP/GreatDevs
[Sony Xperia Z Ultra] Godaemon:
Tried the latest version in the morning using Faux123 Management apk and pimp my Z1.

Major issues :

Hotplug is not working like it should , no matter what you set (max cores online etc) is doesnt work , it always uses 4. Governors were OK.

GPU is also not working fine for me. Setting something higher than 450 (i used 533 and tried 600 a bit) works fine but the frequency remains at max all the time (i didnt touch the default GPU Governor)

I was satisfied by battery and consumption and the performace was pretty good (achieved a 43500pts after a test run with Antutu).

I suggest to remove the 2.72Mhz since its impossible to stay stable that high and add an extra step between 2450 and 2250. (2450 worked 100% stable for me)
[Sony Xperia Z Ultra] kayrowl91:
lucky you. try a lot of apps but im unable to overclock my GPU. there no extra freq .only 450mhz max
[Sony Xperia Z Ultra] OmarEinea:
Some news about GDv2

As you may know, GDv2 is included in RR builds for now, I was planing to release the next juicy build here as a kernel separately after finishing adding some new stuff,

but I didn't get much time to do both, so maybe next build or so, and for now I can tell you the "so far" changelog (other than the part you already know included):

GreatDevs V2.07:

Add CPU overclocking upto 2.41 GHz

Allow CPU underclocking to 288.8 Mhz

Allow Using 2.34 GHz and 2.11 GHz CPU freq steps

Added Fast Charge

Added MSM-Sleeper which limits max freq when screen is off

Voltage Control

Added Govs: SmartAssv2, Wheatley, LionHeart, LagFree and Intellimm

Added I/Os: VR, ZEN, SIO-Plus and Tripndroid

Added CPU freq limiter

Added KCAL support for rgb/lut control

Some optimizations

Source code with detailed changes can be found here: https://github.com/GreatDevs/kernel_sony_msm8974/commits/GreatDevs

Now of course many of these are implemented as initial code and may not work properly as I didn't get time to test them,

and the kernel is barely beta, but I hope it'll be satisfying enough for now :)

Next RR build is building ^_^

Omar.
