Perfect, now I have all I need from this kernel :)
[LG Optimus 2x] 60nine:
nope, no tethering used... except it turned itself on automatically somehow and without my notice...

the phone was connected only at my home wifi network...

the log was taken just after reboot and that was the 1st ever log i ever took (maybe i don't know how to take a proper/usable log? dunno)

btw after a clean install, everything seems to be ok (especially considering battery life) except i also suffer from random full brightness from time to time... ( [MENTION=3783116]pengus77[/MENTION] )

edit:

btw this is how the Kowalski manager app icon looks like under DCikonz theme ;) (thanks to the DCikonz dev who integrated it in the pack - very polite and nice gentleman i must say)
[LG Optimus 2x] manueltts:
Well, now it has happened again. But not at boot. Just at some random moment while using the phone normally (I believe I woke it up to send a text message). I'll try to catch a log (before I'm gona read Tonyp's thread to learn how), if it happens again.

Ok, can you all with the issue try to set your max screen off frequency to 456MHz? I need to know/understand if it's a timing issue with the delay/blocker I coded.
[LG Optimus 2x] Peppe91:
since 2 days I setted the max screen off frequency to 456MHr and the problem persist... In my case the bug doesn't present every single boot But randomly and more often when locking/unlocking the phone..

CPU Profile switching events

I am using Android Tuner to set cpu freq profiles but it seems to me that resume of default profile after turning the screen on sometimes fail (remains stuck at off screen pars) ... anyone with the same problem with other utilities?

Thanks,
[LG Optimus 2x] wfd:
I got this bug couple of times. Fixed by turn off/on autobrightness.
[LG Optimus 2x] marcof93:
It is appening also to me with cpu adjuster..but only for 10-15 seconds, than it works good
[LG Optimus 2x] Gonox:
But if you look at time of the screen off profile you will notice that profile doesn't activate it stay stuck on a profile (default or screen on)

Cm 11
[LG Optimus 2x] marcof93:
Yes the time says this, but I think it is used, because I have max 300mhz with screen off (and I set it in the default profile), but when I turn on the screen it is too much slow, so I think it is active when the screen is off
[LG Optimus 2x] Kenks:
i set to 456 MHz but i did again after some time. İ set it 6 hours ago and it happens just once
[LG Optimus 2x] 60nine:
i don't recall if this has been answered yet - but is anyone else getting the +1 (+2) charge percentage everytime you turn the screen on/off...

no matter if i do it 5 times in 10 seconds it's still going up... (maybe a powerbutton charge feature of some kind lol jk :) :) )
[LG Optimus 2x] pengus77:
Guys please stop using screen off profiles amd just set a max screen off frequency in trickster. Apps that set profiles do that before the kernel enters suspend and wake up after the kernel resumes. So, the app tells the kernel to set max freq at N mhz, the kernel stores it for resume and sets its max screen off freq. When it resumes, it sets the stored speed (the profile one) and then after a while the app restores the right speed. Kinda useless uh?

Yup that's the solution, and if you will integrate a governor like conservative for deep sleep it will be awesome

[LG Optimus 2x] ensboarder:
Where is that option on trickster?
[LG Optimus 2x] slomo90:
I have set it to 456, but after reboot the max brightness bug was still present. Fixed by switching on/off auto brightness. I'm on cm11 with alpha 28.
[LG Optimus 2x] flat__line:
Do I need 'frequency lock' to have them persistent after boot?

Thanks...
[LG Optimus 2x] flat__line:
Technically, how is the constraint on the max screen off frequency passed to the kernel?

The kernel does not support UCI configuration (as expected e.g. by STweaks app), am I right?

Thanks,
[LG Optimus 2x] 3c:
Hello, can I ask you how does trickster does it? I've been told trickster has a dedicated tab to fix this? Is it a kernel setting or a trick ;) to reapply screen on frequency after a longer delay?

I'd like to add support for your kernel in Android Tuner, but not sure where to start considering I don't have this particular device. Thanks.

EDIT: Sorry, a little redundant with previous post, which I didn't see until the page refreshed.

Im get the screem brightness bug when im leave the screem turnof automatically. when I turn off the screen manually through the on / off button, the bug does not happen.

Im remember that ocour after im change the min freq screen off to 465. Im will go back to the default to confirm.

[LG Optimus 2x] pijas82:
nice,for me works perfect
[LG Optimus 2x] pengus77:
Technically the kernel is told via sysfs to set a dedicated max frequency when it enters early suspend. The path in question is /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq and it's r/w. Your app needs only to read from it when it starts, to set the UI params, and write to it when the user changes it. It's all handled in kernel space, so your app doesn't need to bother resetting the right frequency when the system resumes. Both Trickster and Cpu Adjuster support it, being a standard path on all the kernels that provide the feature ;)

[LG Optimus 2x] 3c:
Thanks, it seems like the old OC/Deamon I just removed support for ;) Support will be added for this specific path in next update so that the selected profiles will adjust screen off frequency only once. Can it be adjusted on individual cores separately or only core 0 which will then apply to all cores?

Great job,my 3rd charghing complete and i'am getting great results(never before) with latest kernel.

You can't uv with -5 multiplier..it's -10 multiplier..because of tegra chipset...afaik -75 would read as -70 or -80

[LG Optimus 2x] aigaming:
Trickster says 75;)
[LG Optimus 2x] pengus77:
Yeah, that's because trickster doesn't know about the real voltages, just sets them blindly. What [MENTION=4576689]ivaneris[/MENTION] said is true, our phone can't handle .5mV changes, only .10mV steps.
[LG Optimus 2x] aigaming:
So what that means? Trickster not undervolting at all,i have no issues?tnx
[LG Optimus 2x] xperia u20i:
it's undervolting but in 10mV steps...so if you select -75mV kernel will set to -80mV,something like that...it means that is not very precise...if i understand good

[LG Optimus 2x] Peppe91:
1) It's recommended to undervolt max 50mV for all frequency.

2) row and cfq are the bettest tuned.. I prefer row like (I think) most other users do.

Indeed, it's the simplest one and the most unlikely to crash/explode :D

Please note that the higher amount of tuning went into row, cfq and deadline. Those three are the ones I personally prefer over the others, and the ones I constantly take care of :p

I didn't knew that even deadline was a valid choice... I tried between row and cfq and prefer row but now... Deadline is even better at first look! Not placebo effect... Since now deadline is my favorite choice! All tasks seems immediate!

Hi, I'm using tonyp's cm11 with alpha 28 as of now and it seems that everytime I wake up from sleep the wifi is disconnected. When I check the available networks, my home network is listed as out of range. Turning wifi on and off wouldn't fix it so I'd have to reboot to reconnect. Today the on/off toggle didn't even work to see if I could reconnect. I have the logs attached and hope they will be useful.

Guys, I'll probably switch back to the more stable bcm4329 wifi driver. Seems like the new driver/firmware is a bit unstable and I don't like it. I'll spend the day trying to fix bcmdhd but I'm not sure if I can get it to work correctly. I'll keep you posted.

[LG Optimus 2x] 60nine:
so you think that the new driver is the reason of all of our bsods and reboots?

(i woke up this morning with a black screen again - didn't catch the log, but i assume i have the same problems as [MENTION=3435730]xperia u20i[/MENTION] stated already)
[LG Optimus 2x] xperia u20i:
i also think that new wifi drivers could be the problem...most problem appears when wifi is on...especially in deep sleep...and some times it seems that i lose connection while phone is locked but connect so fast that i could not see if wifi icon missing or not...i'm sure that connection is lost because i get message on viber when i unlock phone, at first i was think that is coincidence but it happened few times...will see how will be with old drivers...:fingers-crossed:
[LG Optimus 2x] 60nine:
i agree... sometimes wifi turns off after sleep (it's turned to "always on" in settings), and there is no way it could be turned on again except you reboot your phone...
[LG Optimus 2x] xperia u20i:
i never have problems with turning wifi on,did not completely lose connection, but something is strange with wifi drivers, for sure...and i'm sure that the masters will solve that problems... :highfive:

everybody should disable zram, as that fixed for good the long wake time after power button pression (aka for the impatient BSOD :D )
[LG Optimus 2x] yuden:
Great work. Thank you! Just to share my experience, with Cm11 and alpha 20, I don't have the slightest problem with Wifi. The phone feels so good... I haven't updated the kernel so far. Everything I need works great. The only thing that bothers me is the phoneui lag that I couldn't fix with the link you provided.
[LG Optimus 2x] hkkp:
I can confirm that. I have a Nexus 7 which linked to a same email account, when a email came in I got a notification immediately from Nexus 7 but the the phone remained 'silent', until I turn on the screen manually.
[LG Optimus 2x] stv0309:
This is happening to me as well after alpha 20. Gmail, Whatsapp and other apps only pull msgs when I turn on the screen from deep sleep. Another thing using alpha 26 and 28 my phone uses 7 to 8% per hour (after 5+ charging cycles) and BBS does not show what consume the power as the stats show 90% of the time the phone is in deep sleep.
[LG Optimus 2x] rzlatic:
no wifi problems whatsoever with alpha28, the router is thomson TG782 if that's important.

however today me and kernel we have "the lights of bethlehem" day - the kernel uses the display like we have battery of 7000 mAh at least :D meanwhile, the screen is absolutely the mightiest battery drainer, to the fact that i avoid to use the phone excessively as every minute of screen-on means a lot of battery down even when autobrightness is ok.

anyway, turned off the autobrightness for good, set brightness to *a bit* over dimmed.
[LG Optimus 2x] andreilica:
+1 same here. Better than before. Sometimes with the old one I got often disconnected from my router. Now, it's all perfect.

I am not saying my phone have problem with the new driver; I am using The ROM 27 with KK 3.1 build 20 which is with the new driver. I never have problem with old driver and new driver until build 26 and 28. Wifi is connected all time, but application (like whatsapp, gmail) do not pull msgs when phone in deep sleep state. When I manually wake the phone up then the msgs start coming.

[LG Optimus 2x] echo_21:
Would you like to be more specific? Which CM11 ROM build? Which kernel alpha build? What do you mean with " ... the new wifi driver ... goes OFF"?

Do you mean that the Settings|Wifi State has been set to "OFF"?

Or do you mean that the Settings|Wifi State stays "ON" but Wifi does not work anymore?

Or do you mean that the Settings|Wifi State stays "ON", Wifi still works on screen off (check this by ping from you PC to your phone) but push mail notification does not work anymore?

Does Wifi work again when screen is on again?

Or do you have to reboot to re-enable Wifi?

Or do you have to remove the battery to re-enable Wifi?

See, you wrote a one liner. And I have at least 8 questions you could have avoided easily. I really appreciate that you contribute here. But we need more high quality posts to let the devs fix the issues as soon as possible. No bad feelings...
[LG Optimus 2x] marcof93:
Sorry, you wright!!

Wifi state is always set to ON but when the screen is OFF it stops to work..when I turn ON the screen it starts to work again..push notifications starts to work again when I turn ON the screen and I can't use services like AirDroid when screen is OFF (and wifi set to ON of course).

I had the same problem on 26/12 CM11 and also the latest alpha, with all the latest releases of KK (but I'm on the latest alpha 28).

also set

dalvik.vm.heaptargetutilization=0.75 (i belive the stock 0.25 is wrong value, it's good on dalvik.vm.heaputilization=0.25)

this will grant some more free ram and will start garbage collection sooner.. maybe some % of battery will go out with this but i find it's really good improvement for standard apps and usage.. let me know

:)
[LG Optimus 2x] echo_21:
Up to now there is no evidence that your wifi connection really drops during screen off at all. It might also be the case that "only" push doesn't work correctly (by whatever other reasons). I would recommend an easy test whether or not wifi stays during screen off:

1. Find out the local IP address of your P990 (e.g. 192.168.178.23)

2. As long as the screen of your P990 is on, ping this address from your PC that is also connected to your local net (e.g. "ping 192.168.178.23" )

3. don't proceed to step 4 if all ping packets use to get lost; repeat steps 1 and 2 instead

4. switch off the screen of your P990 and repeat step 2

5. don't switch on the screen; wait 20 minutes; repeat step 2

Please report results
