Just had my first random reboot with v13 (never had this issue before on Z1 with DooMKernel) about to try v14 but feel this could be a new voltage problem.

Edit - Just flashed v14, Snakecharmer working nice :) will monitor this version for reboots and post results if any.
[Xperia Z1 Original Android Development] Destroyedbeauty:
Damn, this was not expected.. Thank you!
[Xperia Z1 Original Android Development] LLars_PL:
Wow! Thanks! Damn you Rock!
[Xperia Z1 Original Android Development] mikailmohammed:
Running tests now.
[Xperia Z1 Original Android Development] ekanix20:
V14 working well with latest iHackers. :)

Intelliactive governor and row scheduler.

Nice, will jump from aosp ship once intellplug is implemented. Pimped kernel only giving me an antutu score of only 25000+-?:confused:
[Xperia Z1 Original Android Development] mikailmohammed:
5 percent battery loss using power amp for 1 hr. So far it is much better that V12 in terms of speed. i get no lags. Giving my phone a full charge and will test general performance once that is done.
[Xperia Z1 Original Android Development] LSD DREAMER:
Any body els have random reboots on 14. Not sure if its kernel or rom related
[Xperia Z1 Original Android Development] DooMLoRD:
Hey guys please do thorough testing of v14 kernel with various permutations and combinations of settings and please do report back with your findings...
[Xperia Z1 Original Android Development] CappyT:
Why with hotplug i have all cores online and with mpdecision no?

Something wrong here...

Is intelliplug in the kernel? Pimp my z1 says there isn't...

Inviato dal mio C6903 utilizzando Tapatalk
[Xperia Z1 Original Android Development] Destroyedbeauty:
Don't ever disable any hotplug driver, if there is no replacement one to use. It will cause more problem than good.

And no, Intelliplug and those goodies are in the work but they require custom WLAN modules and finding those isn't easy..
[Xperia Z1 Original Android Development] ashirokung:
Random freeze sometime, 2times for 10hour after flash v14
[Xperia Z1 Original Android Development] guddu2011:
flashed v14, random reboots 3-4 times, while opening music player, camera, and settings.
[Xperia Z1 Original Android Development] harfot:
No such issues, try to wipe cashes.

Which ROM, govenors and i/o's?
[Xperia Z1 Original Android Development] lil-diabo:
Flashed the kernel soon after it was uploaded (Yay for subscriptions)

Haven't experienced any reboots and it seems that it's all running rather smoothly.

Constantly switching between governors and I/O's (Still haven't found a winning combination)

I do have a question regarding one of the governors.

Is it normal for SmartassV2 to max out core 0 all of the time?

I've read up on it and from what I understand it's supposed to ramp up?

Basically at the moment all it does is max out core 0, and depending on usage maxes out other cores
[Xperia Z1 Original Android Development] guddu2011:
RomAur 7.0

intelliactive

cfq
[Xperia Z1 Original Android Development] mikailmohammed:
So i used intelliactive and cfq with min. freq. to 300mhz. I still experience higher battery drain than adv. stock. I didn't wipe caches or anything like that. With using power amp i lkost 10 percent battery in less than 1 hr.

The kernel is rather smooth though and works well in all apps. That battery drain though.
[Xperia Z1 Original Android Development] ashirokung:
already wipe cache with TWRP,

stock rom with deodex,

cpu : interactive, max 1958MHz, cfq

gpu: max 320

wipe again with CWM and use I/O row no issue.:D
[Xperia Z1 Original Android Development] Wolfbreak:
Will try V14 now, im still on V12 but i dont have OC and i use intalliactive and fiops, Multi Core Power Savings on Moderate and Battery is like on stock for me but its alot smoother.
[Xperia Z1 Original Android Development] :
For me, I don't wipe anything. I just flash it from V12 in CWM.
[Xperia Z1 Original Android Development] mikailmohammed:
How's it working for you so far?
[Xperia Z1 Original Android Development] :
Stable. No problems at all. It's been a day since I have V14 installed and no problems for me.
[Xperia Z1 Original Android Development] ekanix20:
Same here.

[Xperia Z1 Original Android Development] mikailmohammed:
What settings are you using? Maybe I need to let the kernel settle for some time then it may stabilize.
[Xperia Z1 Original Android Development] MysticEnforcer:
Hi,

i use v14.

oc doesn't work correct.

i set 2.4ghz at max,

reboot one time and

it jumps back to 2.2ghz.

tried all governors,

everytime the same result.

edit:

now i go back to v13 and i don't change anything, just the kernel.

it boots up with 2.4ghz and stay there.
[Xperia Z1 Original Android Development] raziel123:
Doomkernel V14

Doomlord I was getting severe stutters in the UI on V14, whilst scrolling accross home screen etc.

I had it on the Interactive governor, 300 min - 1.9ghz max.

reverted back to Advanced Stock V3 for the moment,

regards
[Xperia Z1 Original Android Development] mikailmohammed:
The kernel behaves weird at times. With intelliactive I get my minimum freq going to 1.19ghz. Randomly and not hitting 2.2. Small Ui lags. But it seems unstable in its behavior. Back to v3 adv stock for me
[Xperia Z1 Original Android Development] Duvel999:
No problems here on RomAur V7.

Maybe Root problems?

Got Supersu installed? :good:

Got Busybox installed and a Kernel Tuner app?

On V12 & V13 I got Reboots.

Kernel needs a few days to settle..

I use SmartassV2 & Row

V14 works good:cool:
[Xperia Z1 Original Android Development] snekkarn:
ihackers v4.1 minimal

Intelliactive

Row

And other adjustments in fauxapp. Best rom and kernel ever! No freezes og random reboots that i got with RomAur.. Having very good batterylife and all in all super happy FINALLY with my Z1.. Was really considering selling it..

[Xperia Z1 Original Android Development] mikailmohammed:
Hmmm. Maybe I am not giving it time to settle. I am on stock rom. Will try again with your settings. You seem to use a lot of power though for that smartassv2 and row.
[Xperia Z1 Original Android Development] HellRoot:
is there any gain of using this compared to stock kernel in regards to battery life and performance?

i get quite good of both on stock... but let me hear your experiences with this kernel...

i used doomkernel on my z and s... and loved them... but i see some people state that this in unstable and glitches from time to time..
[Xperia Z1 Original Android Development] harfot:
Yes, some - you always hear more from people with problems than us without. I had a 2% discharge on stock rom and it's still the same. No glitch and no lag. But I gave it 12 hours to settle before changing anything.
[Xperia Z1 Original Android Development] cowen1000:
[MENTION=231602]doom[/MENTION]

Your kernel rocks. I have no issues, totally stable. Running v14 with criskelo 5.1 rom.

My current configuration which i find best.

Overclocked to 2.4.

Interactive govenor.

Mp decision enabled.

Cfq scheduler.

Power suspend on.

Dynamic file sync on.

Antutu score 35600

No boot loops, no lag. Made my phone so much smoother. Battery good too.

Keep up the good work
[Xperia Z1 Original Android Development] peteri8706:
[MENTION=2784807]DooMLoRD[/MENTION], reporting back on v14.

Stable for the most part, but random freezes and then reboots when using random apps or when surfing the net.

Settings:

ondemand- no overclock using snakecharmer.

Cfq I/O scheduling at 512 entropy - only using internal sd, external set to off.

Fastcharge at 500 AC.

All other settings left at stock.

Running RomAur v7, with .757 tft. And xposed (latest) with gem and gravity box for minor ROM tweaks.

Used fauxclock to control the kernel.

Back to v9 of your kernel where all is back to stable, no freezes or reboots.

Battery was better on v14 though.
[Xperia Z1 Original Android Development] :
CPU Control (Voltage boost off)

GPU Control (Nothing changed)

Power Management

Miscellaneous

Everything in I/O tweaks are off. Colour Calibration remains the same. Memory Management remains untouched.

Nothing turned on under Touch Screen and I doubt Sound Control has got anything to do with the problems.
[Xperia Z1 Original Android Development] lil-diabo:
You're one of the lucky ones, looks like you can overclock past 450Mhz on the GPU.
[Xperia Z1 Original Android Development] Ashray_Vk:
Even I'm not able to overclock past 450 Mhz
[Xperia Z1 Original Android Development] cyrom:
Hi [MENTION=2784807]DooMLoRD[/MENTION] , one quick question, are the feature of doomkernel v11 still on v14? i know tap-to-wake has been disabled on 12+ and i just wanna know if this still works on v14. thanks doom!
[Xperia Z1 Original Android Development] Ahki767:
Yes that feature is still in the kernel
[Xperia Z1 Original Android Development] DooMLoRD:
For now just CPU voltage control is disabled... I am working on getting this to work...
[Xperia Z1 Original Android Development] :
Take your time. Slow and steady. (Can I get an early access.. I mean I can test for you)
[Xperia Z1 Original Android Development] andino:
I'm not able to toggle dd2w with Pimp my Z1. Says that its disabled in the Kernel.
[Xperia Z1 Original Android Development] DooMLoRD:
Intelli thermal is back!!!
[Xperia Z1 Original Android Development] omegahanggara:
Which version?
[Xperia Z1 Original Android Development] :
Yup. It's disabled because of problems. Battery drain I think.
[Xperia Z1 Original Android Development] Destroyedbeauty:
It was disabled because of battery drain & touch driver related wakelocks.

Correct!
[Xperia Z1 Original Android Development] DooMLoRD:
Added ZRAM support!
[Xperia Z1 Original Android Development] Destroyedbeauty:
This ZRAM thing, what does it do actually? *confused*

And are you using latest FauxClock app??:o *envy as hell!!!*
[Xperia Z1 Original Android Development] omegahanggara:
What is recommended size for ZRAM?

With smartassv2 is it normal for 1 core to be constantly maxed out?
[Xperia Z1 Original Android Development] kantk20111:
Hey guys, I'm sure this is a repeat question but the search function isn't working properly for me and the thread is really long: What is the optimum governers for the cores for good battery life? Thanks for any help.

Ah yeah. Totally missed that haha.

Just flashed v15. Can't wait to see how it runs.

As always - better than stock! :)
[Xperia Z1 Original Android Development] MysticEnforcer:
in this version i can't oc up to 2.4ghz and

i can't deactivate snake charmer.

when i set 2.4ghz at max and

reboots my device,

it jumps back to 2.265mhz.

why?
[Xperia Z1 Original Android Development] raziel123:
Doomlord cam you tell me the optimal intellithermal freq and core temperature settings?

Regards
[Xperia Z1 Original Android Development] ThibaultAnd:
I eventually RomAur v7 (clean installation) and it's now stable ! Thank you (I'm now with V15 version)
[Xperia Z1 Original Android Development] Destroyedbeauty:
Then your chipset can't handle the clock frequency thanks to;

1) Stress / freq throttling & misbehaving / not enough voltage to power the CPU for reaching that freq.

2) Snake Charmer is there for ticking the same MAX freq for all four cores at once! That is why you can't deactivate it!
[Xperia Z1 Original Android Development] MysticEnforcer:
when i flash back to v13 then i can oc with 2.4ghz at max.

a guy from android-hilfe.de can deactivate snake charmer.

hmm :D
[Xperia Z1 Original Android Development] Destroyedbeauty:
Why does someone even want to overclock to that frequency on a phone that already got a small amount of heat issues?

And why does someone want to deactivate SnakeCharmer and cause more headache than good?

:rolleyes:
[Xperia Z1 Original Android Development] mikailmohammed:
Then complain about battery and heat issues.

BTW my V15 works well so far. How about you? Using intelliactive and cfq
[Xperia Z1 Original Android Development] MysticEnforcer:
oc to max just to test and

i have no heat problems.
[Xperia Z1 Original Android Development] Destroyedbeauty:
My Z1 is sleeping like a baby right now, using Intellidemand and CFQ with a little bit underclock on the maximum allowed frequency (to 1958400 Mhz) and got some heavenly battery life in return. Have written down my custom battery saving settings in a Wordpad document if you want to use them, [MENTION=4808024]mikailmohammed[/MENTION] ?

I am impressed by [MENTION=2784807]DooMLoRD[/MENTION] and his efforts to push the Sony kernel sources to their maximum level and still even beat stock kernel in every aspect. It's a shame that I can't donate, otherwise, you should have a small amount of cash flying OTA to you right now, Doom!
[Xperia Z1 Original Android Development] mikailmohammed:
What's the difference between intelliactive and intellidemand? I know it's something to do with how aggressively the clocks ramp up. Oh yes once locked and in deep sleep it saves battery so much.
[Xperia Z1 Original Android Development] Destroyedbeauty:
I've not analyzed and tracking the frequency and behaviour differences between Intellidemand and Intelliactive that much, so can't give an fair comparison between them. Only that they're freaky battery saving beasts when everything has settled down ;)
[Xperia Z1 Original Android Development] mikailmohammed:
For those interested in smartassV2 please stay away. This governor seems to only operate at max speed and minimum. It causes insane heating on the phone and high battery drain. I used smartassV2 before but it seems to not work properly in this kernel.
[Xperia Z1 Original Android Development] pathanraj:

I suffer overheating while charging in v14(can cook egg easily on it :p)..i want best settings in pimp my z1..to avoid heat and better battery life..bad experience in v14 really battery got so much hot and got stuck on 83% sometimes over all night charging...anyways THANX FOR UR DISPLAY SETTING WITH WHITE BAL and Doomkernel colour really guy u r the one..

Can u tell me best settings of pimp z1 which have better battery and no heating

---------- Post added at 03:47 AM ---------- Previous post was at 03:38 AM ----------

While INPUT 1958 VALUE IN MAXIMUM CPU FREQ it restores MAXIMUM TO NAN AND MINIMUM TO 1190 after pressing back button always..what to.do.i.want to.underclock it to save battery and heat
[Xperia Z1 Original Android Development] mikailmohammed:
I get the same thing that minimum goes to 1190. I am clearing CPU spy and gonna run some intensive apps to see if it reaches the speed or its just faux app not showing that max. I am on intellidemand. On smartassv2 you will get 2.2ghz easy so i am thinking it might be a governor thingy.,
[Xperia Z1 Original Android Development] pathanraj:
Cpu Set shOWING MAX 1958.MINIMUM 300

My cpu set is showing max 1958 minimum 300 but pimp kernel showing max 1958 which i set but restore minimum to 1190....actually pimp restores min 300 to 1190
[Xperia Z1 Original Android Development] raziel123:
try the faux app, it doesn't have this issue as far as I can tell.

although I did notice that the minimum speed jumps to about 1 ghz on touch and drops back to 300 mhz. Also I recommend setting High speed_Freq to the (Maximum CPU speed you set) as having it higher than max speed will override the former, I'm running fine with Intellithermal management turned on :cool:

---------- Post added at 11:44 PM ---------- Previous post was at 11:41 PM ----------

Guys anyone have any recommended Optimal Temps for the above?

regards
[Xperia Z1 Original Android Development] Destroyedbeauty:
Read this regarding this issue, from my own experiences..

This is a "bug" with the minimum frequency, thanks to the MP-Decision hotplug driver by Qualcomm that boost lowest freq, in this case 1190 Mhz, for creating this "Project Butter" smoothness, and thus, cheating for speedier, latency free UI response and removal of any possible lag. Good for performance, bad for battery life.

This is nothing we can fix, thanks to that Qualcomm made the stock MP-Decision driver closed source - instead, this requires an replacement hotplug driver (Intelliplug ofc! Beastly good magic there!). But I can say that once you've set-up everything in Pimp My Z1 by saving every setting (verifying that you got an echo xxx > xxx/yyy/xxx/etc popping up on your screen) - you don't have to worry after that by any meaning.

For saving anyone here from further headaches, read here below..

After reboot, in case you've set everything to replicate and stay on your desired settings, the app will make sure that everything is getting adjusted and tuned / enabled / disabled / whatnot to what you ticked before the rebooting procedure. Don't worry, MP-Decision is crap, we know, but every setting in Pimp My Z1 is saved and set on boot. Even MIN and MAX CPU Frequency is enabled to desired settings. If you want any photoevidence, pm me!

And regarding optimal Pimp My Z1 settings - read this reference / "README" for getting good and balanced settings that doesn't sludges down your performance but still keeps the battery drain at tolerate goodly levels. Remember though, this is just my reference on a good battery friendly set-up - this works for me, but maybe will unleash Cold War nuclear crisis for you. Here we go anyways..

Pimp My Z1 settings!
