I'm on "0", the weak one...

For now I'm using folowing Voltages: 1262 1237 1200 1162 1125 1087 1032 1000 962 937 875 837 787 750

PS: I don't know why The-Best-Kernel/ROM-Thread is closed. User experience with different Kernel/ROM in one thread is intersting and helped me to find the best working Kernel for my device...

The best benchmark results I've got for now:

I don't get it, this kernel used to work fine. Now it crashes regardless of my voltage settings. If I manage to get it to boot all is good usually so it must be the voltage

After a few days on PH85 kernel, I must say, the wakelock problem seems not be solved. It doesnt appear in BBS, but battery drain shows: its there. If I use 3G, sometimes battery drain per hour is about 1,5% (normal) and after some times (may be a half day) battery drain is 7-10% per hour (same as the wakelock problem). So I´m sure, wakelock is not seen, but issue still resists...

If I use 2G or flight-mode in the night, battery drain is much better than before, not massive drain at no time. But I want to use 3G...

Use DS battery saver to regulate deep sleep action :)

Anyway news coming but not so shortly:

- fastcharge

- unlinked GPU (thanks for this to Laufersteppenwolf)

- compiled with linaro toolchain 4.7.3 to optimize a bit more

- some other more

This new will come in the next week because now i'm on a pentium IV and the compile time is very very slow....

I don't like to deal with this pc but if i'll have more patience i'll upload the 1.55 version with this updates and then the 1.6 with the new laufersteppenwolf features :/

1.55 uploaded

Still crashes and glitches everywhere. Fix the damn voltages for variant 0, or release a stock clocked version. Totally unusable otherwise, but when it boots its a nice kernel! Please focus on issues before features

[LG Optimus 4X HD] Pesach85:
I rebased the voltages in this version and i raised all, so, i repeat, the result must be different from phone by phone.

I have great stability with this setting and zero glitches, tested it for long time, as i test kernel usually for long time before to publish anything.

So the maximum i can do at the moment is to write: "BE CAREFUL, THIS IS NOT STABLE FOR ALL PHONE, I CAN JUST TELL IT'S REALLY STABLE ON MINE"
[LG Optimus 4X HD] @non4:
Well what's odd is any overclocked kernel has the tendency to crash at boot, but if it makes it past booting it runs fine on the default voltages. I dunno, I'm sure its OC/voltage related, only way to be sure is revert clocks/ voltage to stock values. Please make a version like this, the temp_throttle_skin value being raised is enough for me to keep trying to make this work, but it just won't. Thanks for your work mate ;)

Your kernel seems very well. I think you should make something like iodak kernel v04 with USB OTG and working USB tethering. That will be great.
[LG Optimus 4X HD] @non4:
Two seconds... Done, here's the link: http://youareanidiot.org/ :D seriously though, its not that simple. Kholks kernel is your best bet for this, he's already implemented USB host. As for the tethering I don't know, have you tried easytether?

[LG Optimus 4X HD] Subhajitdas298:
If I am an idot, you are a genius. As I said, I want a kernel that is super stable, smooth and less heat producing in normal use like iodak kernel, features like kholks kernel. As USB tethering isn't working in iodak, I want it working. Why don't you make it. Everyone wants something like that, not just me.
[LG Optimus 4X HD] @non4:
Its not so easy... That is my point. Its always worth asking if someone will ever implement something but the "you should make it benchmark at 3000000, produce no heat and have every feature imaginable" approach doesn't work. Just wait, new features will be developed all the time, forcing you to flash a new kernel and try them out. Its part of the fun ;)

I was expecting same answer. I am not a complete fool as you think. I know development its not easy as saying, but trying to develop something great should be the target of every developer,isn't it? Specially on demand.
[LG Optimus 4X HD] @non4:
Well "you should" should be replaced with "would you consider" or "can you please", it sounds nicer and less pushy to devs, of course we all want features like these but we need to respect that these people do all this hard work, for free, in their spare time and don't expect much back. Not hating on you or anything, just going from experience I've had some nasty responses when I've worded things the way you have. Especially the "made by a child" remark. Play nice :D

[LG Optimus 4X HD] Flying_Bear:
just to say, this is my daily driver. battery is decent, and it's performance is better (for me) than iodak or werewolf, since this kernel has 1300 as limit when throttling, which is still a lot, and it's battery throttle is at 48 degrees, which is also awesome, as default 43 is too low for me.

"Would you consider" and "can you please" is asking only. I wasn't just asking, I was suggesting instead. I thought every developer likes good ideas, but never thought someone would get hurt. Sorry, if I hurt anyone. Maybe my idea wasn't that great.

About the "made by a child" comment, truly in front of iodak or PH85 kernel or even stock kernel WerewolfJB kernel for stock is something like that. I don't want any kernel that mess up everything and make my phone unusable, even it is for free. I don't know if anyone wants something like this.

About playing nice, I always play nice but don't comment unfair way. I always write my feelings. It may hurt someone though.
[LG Optimus 4X HD] @non4:
So do I, but in the correct way. A bug description with log/kmsg would be a lot more beneficial to the dev than an insult. All devs are gonna produce something buggy at some point, its the nature of it. And that is all I have left to say, as I feel this conversion is going nowhere

Buggy may be for others, on my phone goes perfect. Everything here is AS IS and I can't test on multiple devices.

Your kernel is great! Its just not compatible with variant 0 devices, 1.7 is just too much. If you made a non overclock variant of each version then everyone could enjoy it ;) I'm sure as you managed to overclock it in the first place this is not beyond your skills. Thanks for your work

Bug report:-

1. Found bug using vibration. Though it doesn't matter to me cause I don't use vibration. Vibration feedback don't appear in startup & shut down as it was in stock.

2. WiFi direct didn't work. SmartShare doesn't recognise connected devices. (Optimus 4X and Optimus L5)

3. Problem with auto media scan. Media scan sometime doesn't work when SD card inserted.

4. Many lags.

5. Clock speed seems to stuck on 1224 most.

6. Wakelock when charging. 51 MHz constant. Phone heats up.
[LG Optimus 4X HD] @non4:
BTW the 51mhz sometimes gets stuck if you don't wipe dalvik cache. If you already did then its a bug, but one I either didn't have or didn't notice

What version are you using?

The number 1 seems not a "bug" or just make clear on what you mean with bug.

The issue 2-3 could be resolved using different modules (i have not these issues) but we should see if it's really kernel related with a logcat and/or dmesg.

Lags: it depends on how you configure cpu clock / governor / cpuquiet, I have not it, not more than the stock, just less lags (or it depends on what you mean with lags) .

Wakelock at 51 Mhz charging is normal on every kernel compiled with stock sources. Phone heats up is controlled and it not goes over 43 degrees if the sensor works fine.

As it's given this message does not sound like a real bugreport.

[LG Optimus 4X HD] Bogeyof:
Just to say, for me its the best kernel at the moment!!!

I tested all custom kernels (for stock) and I will do in future on any update (hope kholks kernel will be a good one in future), but I always came back to this kernel, for me its stable and all things function, its fast and smooth.

Performance is great with standard settings, I dont have to change anything after installing and booting, I got over 14700 points in AnTuTu, thats enough...

One little thing, I dont really believe, baseband-xmm-power wakelock is solved, I think its only "supressed". I still have times, where my phone drains with 5% or more per hour in standby, BetterBatteryStats shows nothing special and DeepSleep is over 80%... But mostly it drains only 1-2% with exactly the same apps and configuration in standby. So it was before with the wakelock problem, only I could see it also in BBS...

Same behavior in all other kernels, which "declare" wakelock issue as solved, I think its only supressed...

May be its partly solved, cause I didnt have drain in flightmode anymore since 2 weeks. Before I even had in flightmode some nights with 30%-50% drain.

I have cpu variant 1, just for info. May be I could even reduce the voltage a little, some tests seems ok, but I let the things as they are. Battery drain in use is "mid - high", ok, for such a performance u have to pay. Battery drain in standby and flightmode seems very good (sometimes I got a higher drain, as described, think its still the wakelock issue).

Many thanks for ur work, may be u can port some more goodies in the future. But its also a good thing, that this kernel is not overloaded with tweaks and patches and addons...
[LG Optimus 4X HD] Subhajitdas298:
OK. If I cut out 1,2 3 and 6 but 4 and 5 disapoints me. I got some lags on playing AVP. In iodak, it was smoother. About setting clock speed or governer, I didn't modify anything. Checked with Show cpu usage option in hidden menu when playing game and then with trickster mod after game end. In iodak kernel it was 1600 MHz most. Please don't mind but iodak is best at gaming and regular use. Only advantage I found in your kernel is the working USB tethering.
[LG Optimus 4X HD] Pesach85:
You should change governor/CPU settings to find the best values :)

[LG Optimus 4X HD] LamerDuck:
well...

about the wakelocks...

i wonder, how people here (especially kernel developer, who should know better) always try to change kernels to get rid of wakelocks.

correct my if i am wrong, but a wakelock is sent from an application to the kernel to wake the phone from deep sleep and fire up the CPU.

the kernel cant decide if the wakelock is important or not, so he accepts it. he has to, otherwise things on the phone wouldn't work as expected (SMS missing, losing data connectivity, losing wireless, not syncing app, etc etc, depending on the wakelock you suppress.)

so not the kernel is the culprit for wakelocks, but the apps are.

if you want less wakelocks, dont use apps that produce them.

for the specific baseband wakelock, the baseband is the bad guy.

what does the baseband do?

it connects your phone to the net of your provider, be it 3G, UMTS, Edge, GPRS or others.

where does the battery drain come from? (apart from people having installed skype)

theres a special hardware behaviour in about every phone, that consumes battery like mad:

HSDPA

if you have UMTS/HSDPA/3G enabled in settings, but you have only low/none reception, your phone tries to connect to a HSDPA-net over and over again.

i've had 5-10% battery drain by hour just by having 3g activated, because at my home the 3g signal is very weak, so the phone is always trying to connect, losing signal, trying to connect again etc

the problem: this seems to use wakelocks and is not handled by the low power core.

again: connect me if i am wrong.

but if i am right, then there wont be _any_ difference from kernel to kernel regarding wakelock counts.
[LG Optimus 4X HD] Pesach85:
I have to be honest, i have not a real idea of the cause of wakelock, i trusted on araragi patches which disable some init script for baseband wakelock

From werewolf-Kernel thread:

Exactly and as long as the LP core is active, the beast (quad core) is inactive ---> we are still saving power, even if we OC.

also we don't use a higher voltage for 600 as we did for 500MHz

In werewolf-Kernel thread, there are discussions for higher frequencies of LP core. Seems logical for me, may be its possible to set LP core freq. to 600 MHz or give the possibility of an interface (trickster seems to handle it) to set the value by myself? There is an option in Tegra overclock to set only LP core, but in this kernel max. frequency seems to be 412 MHz. Also there is an issue in tegra overclock, after uncheck this option, all 4 cores are permanently online, so battery drains more after check and uncheck this option (u have to reboot). But if u want to save battery the option to set only LP core is great, Phone still function (ok laggy and slow) and save a lot of battery. So with higher max. frequency, this could be an option to save battery if needed (for example only 10%-20% Battery left)...

I can release a V2 but it has still two awful bug:

- seems this kernel has some setting which hate overlock... and i can't stil figure out how to solve

- the battery drain is still high

V2 Changelog:

- Various bugfixes from different authors in the net

- Zram updated with Snappy google compression, it should give more i/o speed

- araragi features with the new inspired Livecolor code (sorry but i don't know how to activate)

- Clock table on steps of 51 and 102 mhz (experiment to see if it may give some difference in performances or battery drain)

- Edited skin throttle to 50 °C

- LP core voltage table editable in Trickster mod

- Enabled Swap

- Enabled 100 200 and 300 mhz clock step usable

- OC for gpu and ram

- Compiled with Linaro toolchain 4.7.4 and optimizations

Things to do: reduce battery drain as soon as possible
