strange. i cant go under -25mv on PVS3 without stability issues :/. but then, it doesnt matter anyway since the batterylife already is awesome with stock values. i just like to get the most out of my devices. btw: can someone recommend to throttle the max clock? i did this on my sgs2 all the time and it improved the battery without sacrifiyng much performance.
[G2 Android Development (D802)] dukat0s:
U can,check under my device score =) go,to top 20 then my device or i,ll post some scennshots this afternoon detail etc

Btw i never change the high temperature property it always off stocked. =) maybe my psv is way faster dunno what i,say
[G2 Android Development (D802)] :
Wahouu :good::good::good:. I see it in Antutu but we can't see the detailed score.

How can you achieve this score :confused::eek:

I'm impressed with your score, I'm more interesting in the detailled score to see where are the huge improvements.

No tweaks, scripts or something who can improve the score compared to the current scores?

:)

i'm using Cleanrom XE 2.0, maybe i must install another rom ...i will report late about it

As i,said,viking no,scripts,mate.only rayglobe rom and lewarne v2. I send the details this afternoon!!btw note 3 running 4.3 3gb ram and sux at,antutu a few,friends allready sold n3 for g2.imagine antutu with the 4.4 kit kat and this awesome kernel.43000+ easy :)))

No script no tweak app while using V 2.0 Android OS is very high and stuck at 3 core online all da time battery drain like water lol...Compare with V 1.3 Android OS use just 19% still don't know what cause this problem

PS.Notice that after boot up the phone when everything load up completely and all core seem to be normal but after 10 second it kick up to 3 core online and stuck like that even if I left the phone for 1 hour :(

great, thanks. is that also confirmation that the CPU cores are not being excessively active?
[G2 Android Development (D802)] eddytheman:
Still stuck with 3 core online sir :( like I said before it seem to be normal at full system completely load and then couple second it kick to 4 core and back to stuck at 3 core always on...

Yeah, the cores are still kicking in
[G2 Android Development (D802)] thaimeobeo1410:

I've installed v2.0

I'm experiencing the same issue like the others

3 cpu in use, the 4th is offline

CPU temp: 57 to 64 ° C

g.leware ROM 1.06

Edit: The battery drain is remarkable 1% in less than 5 minutes

some times the 4th CPU works but i see it is using high CPU usage while i'm not using any application.

watch the screenshot.

[G2 Android Development (D802)] Partager.info:
If you keep watching the processor usage you will notice that even the 4th CPU is also used few times.

The main problem is high CPU usage in normal circomstances, with battery drain.

Hmmm when I first flashed kernel yesterday I got this overheating problem,60-70 C ,I turned mob off a few minutes and turned it back on,and then went to sleep ,today everything seems normal,no overheating ,temp betwen 30-50,depend on app usage.

You guys can check ,leave it 10h with 2.0 ,maybe kernel only need time to sattle down.

i had to agree with you, after flashing kernel/rom it has to settle down for at least a day or so.. they're adapting to your phone..

for the kernel, in my experience i've seen no strange behaviour on cpu usage, haven't seen the 3 cores active for long period of time.. in other words, hotplugging does works..
[G2 Android Development (D802)] g.lewarne:
well, i am 95% certain of what the problem is now. But thanks to my problems with github (now resolved according to their support people) I had to redo my repo from scratch again (dont ask).

So now, ive got the base bits done, again, and now im compiling a non-booting kernel for some mysterious reason. sigh

Since you've taken a good few looks on the kernel source so far ( :D ) I'll dare to ask a question:

BETA KERNEL !!

Ok so I have been poking around in the code some more trying to figure out the thermal throttling behaviour (rather than using, say, intellithermal/demand/plug)

I *think* i found the values that control throttling temps but it is difficult to say for sure if they actually work or not. Franciscofranco has tried similar means on his Nexus kernels, with some degree of success i believe.

So, features of the BETA kernel:

- Throttling temp raised to 75 degrees ?

- Max temp raised to 85 degrees ?

(SoC thermal limits are 110 so still WAY below the line, and its only a small increase)

- Experimental kernel compile optimisation flags (O3 + other flags used)

Would like some general feedback on temps, throttling behaviour, performance, CPU utilisation etc

All changes are on github for anyone interested

Kernel is attached, have fun :)

---------- Post added at 09:42 PM ---------- Previous post was at 08:58 PM ----------

@ g.lewarne,

I noticed lower GPU performance in benchs (for 2D and 3D... Obviously LOL), than the previous version, not noticiable in general UI (always smooth in animations, scrolling, opening apps, etc...).

I don't know how explain (it would take too long:laugh:) but I doubt that the CPU temp limit before thermal throttling is increased, I mean working... (maybe I was wrong in my PM's ;)), always thermal throttling at about 69/70 °C.

I'm not complaining, just a little feedback as always and it's not a bad feedback ;)

Battery life... It's obviously too early.

:)
[G2 Android Development (D802)] g.lewarne:
im wondering if there is an element to the throttling situation being done in userspace. Ill go through the ramdisk with a fine comb and see what other garbage it is set to start on bootup :silly:
[G2 Android Development (D802)] :
This... I don't know :confused:

Like I said you in PM, I played with the thermald files in /system/etc (it's userspace related?) by changing some values, deleting others for CPU temp and CPU freqs with no luck (and I spent several days to try the changed values one by one) :confused:

And there is also three files related to thermal stuff in /system/bin, something to look into? I noticed also that these files are not the same on the international version compared to the Verizon one for example, not the same size for one file (and they bench higher, I mean the Verizon one->maybe less thermal throttling)...

But I don't know how to read these files... Unfortunately my knowledge stop here, I can investigate more :(

With all stock->thermal throttling at 70 °C and with your kernel (the last Beta) also thermal throttling at 70 °C, same thing. So even if the apps I use don't report exactly the real CPU temp in real time at a few different degrees, in any case the thermal throttling is always at the same CPU temperature (reliable or not). I don't know if I explain right here :confused:

Thanks to take time on this, I realy appreciate what you do and your prompt support/replies :good:;)

As always I'm here if you want a tester... :)
[G2 Android Development (D802)] nic85:
-50mv for all values, rock solid tested with antutu. Psv bin 3
