i think so :)

the phone is workin properly, found no failures right now

OC works well with pimpmycpu, it works also in Modaco Gr5

Is there anything i should look for?

thx
[LG Optimus 2x] fajarep:
nothing, thank you for your report.., i'm going to put to first post...

i hope next kernel will work fine too... :) currently testing, got some SOD several times, next to do some tweak here, and there, to make it SOD free...
[LG Optimus 2x] retareq:
Hey faja is the next version compatible with .28 or only .14 ?
[LG Optimus 2x] fajarep:
only .14 version, sorry about that :)
[LG Optimus 2x] mujju85:
is any1 tried new kernal works on latest miui 1.11.11 as i m still on stock cm kernal
[LG Optimus 2x] montresor60:
Just flashed 1.11.11 (after wipe)

12112011-loc-Preview is working fine!
[LG Optimus 2x] fajarep:
please reply any SOD using 12112011-loc-preview version :) thank you for trying out..
[LG Optimus 2x] Higgsy:
Had it installed for about 1hr on. 1.11.11.

I have had 2 sod in last 30 mins when the phone has gone to sleep but when you pick it up to use it is sod. Going to stick with it, but putting the phone to sleep now to see if it does it again

[LG Optimus 2x] ehmjay:
installed it on 1.11.11.. SOD after a phone call.. ;( ..
[LG Optimus 2x] mujju85:
sorry to ask but what is SOD :o
[LG Optimus 2x] retareq:
Screen Of Death aka blank screen
[LG Optimus 2x] montresor60:
I must be lucky. No SODs and screen resumes super quick from black (end button is displayed almost instantly) at end of call. Wake from sleep is also very quick.

1216 MHz / No UV

Wiped data / cache / Dalvik cache before flashing 1.11.11

Best so far!
[LG Optimus 2x] fajarep:
wow, you have the best phone that handle low voltage :D

thank you all.., going to increase voltage a little bit...

if anyone interested tested an updated, take a look here..

http://dl.dropbox.com/u/15667879/SwiftExtreme-test.zip

i believe this version going working fine without SOD problem because lower voltage...
[LG Optimus 2x] mujju85:
the above test version is working fine on 1.11.11 want to know change log let me check for a day than i will giv review for it

installed on stock 20l, preview version crashed (phone reboot) while benchmarking with antutu :)

installing your test version right now
[LG Optimus 2x] Higgsy:
I just had another one, so I'm gonna test the new test version
[LG Optimus 2x] fire3d:
your latest test version seems stable so far....

one thing, I cannot change screen brightness from settings anymore, but this kernel was not build for stock :) automatic seems to be ok
[LG Optimus 2x] el_liberator:
I installed on MIUI 1.11.11 the latest test version , works so fine , no problems , no SOD .
[LG Optimus 2x] ron_gangte:
I am thinking of flashing this Kernel. But before I do that, I wanna backup the stock CM kernel in case I wanna revert back. Can someone please tell me how I can backup my current kernel before I flash this?

Thank You! :-)
[LG Optimus 2x] Higgsy:
Make a nandroid backup in CWM
[LG Optimus 2x] el_liberator:
make a Nandroid Backup before flahsing this kernel ;)

to return to the stock kernel, restore the backup :D

or re-flash CM Nightly without wipe data
[LG Optimus 2x] ron_gangte:
Thanks, but I was wondering if I could backup the "kernel" alone.
[LG Optimus 2x] helroz:
hello,

Very good job, I love your kernel :)

But i have a litle problem:

On 3G with all kernel=> No problem

On Edge with cyanogen kernel => No problem

On Edge with your kernel or Vorkkernel (all revision and cpu frequency) => when i use internet, i lost my signal and must restart the phone.

At my home i don't have a good 3G signal (50% of time my phone is in Edge):p
[LG Optimus 2x] Higgsy:
do advanced restore and restore only the boot
[LG Optimus 2x] el_liberator:
yes it's possible, by making a script to do yourself and it will flash with CWM

or restore boot on CWM
[LG Optimus 2x] polmone:
One sod at first call... Now try a test kernel... Tnx.

[LG Optimus 2x] Higgsy:
So far no sod with this test kernel, which is promising as the preview gave me 4 in a few hours
[LG Optimus 2x] owain94:
Before I release tweak pack to you advise to remove the scheduler change script?

Is sio better then deadline it not?

If you say it is I will remove the script!
[LG Optimus 2x] fajarep:
based on my testing, simple i/o gives better i/o in random write/read compared with deadline/noop. i think that is suitable for nand storage. but, you can pick any i/o scheduler that you think is best :)
[LG Optimus 2x] helroz:
Thanks for your response ;).

I search but i don't find why alternative kernel made this bug on my phone :confused:

Edit: Ok i have my solution, all work good with bb218. (on bb725 only CM7 stock kernel work good)
[LG Optimus 2x] Gingernut78:
I'm on CM nightly #199 and flashed last night 12112011 preview, a few short calls - an hour of hdmi youtube mirroring - charged with non stock higher amperage charger and a few wifi market updates, so far have had no problems at all.

Great work to say the least, thanks.
[LG Optimus 2x] sacman74:
Everything ok with last 12112011 version.... the best kernel !!!

Thanks again!!!!
[LG Optimus 2x] lucfig:
Everything is fine with the new test release, except when I am listening to music. The same happens, the screen takes too long to turn on. Is there any way I can set my lowest voltage to 256 instead of 216?

Thanks, and keep the great work!
[LG Optimus 2x] fajarep:
the kernel will works at 216 upto 316 if you read my explanation carefully. most of the time at standby it works around 300. i think that sufficient for music playing. so, if you got some task that need high cpu at specific time, your mp3 music will glitch, because kernel prevent cpu making higher clock than 316 to preserve power, while trying to finish the task.
[LG Optimus 2x] fajarep:
thank you all for your feedback.., going to recompile kernel to make it as best as it can, and named it 13112011 version. i'm lowering the voltage at 316mhz to preserve some power too...
[LG Optimus 2x] Gingernut78:
Cant sleep now, waiting on release ;)

wow, you really fast, i just update it..., take a look everyone..
[LG Optimus 2x] joe1660:
i had problem with the kernel of 5/11

the problem was that sometimes the screen rotation was stacking at landscape mode. and the bluetooth was not responding some times. are these problems fixed???
[LG Optimus 2x] fajarep:
got no problem with screen rotation, i don't know about bluetooth. you must check in MIUI/CM to see the problem get happened, sometimes OS bug can make problem too..
[LG Optimus 2x] montresor60:
You mean 'increase', right?
[LG Optimus 2x] fajarep:
I'm lowering cpu voltage, increasing ddr voltage to compesate that.
[LG Optimus 2x] mujju85:
i tried ur latest LOC version on galnet miui 4.0 working great so far tried it out guyzz seems pretty stable :)
[LG Optimus 2x] PartyBent:
Battery life

How is the battery life compared to Vorkkerne and miui kerne ?
[LG Optimus 2x] S0ci0:
miui kernel = cyanogenmod kernel
[LG Optimus 2x] Gingernut78:
I never get enough time to really test out VolkKernel because I get a sod/bsod sooner or later but I can say that this kernel has amazing battery life and not one problem so far with any of the releases, at least on my phone using latest CM nightlies.

Q: Wouldn't it be a good idea for the four main kernel gurus here, Benne, Kiljacken, Fajarep & Spica to join forces and ideas and create a killer P990 kernel?
[LG Optimus 2x] fajarep:
in my humble opinion, if we are joining to make kernel, wouldn't be p990 user doesn't have option to pick which one that suit they need. my kernel itself focus with lower power battery management in standby. because of that, some users complaints about mp3 glitch playing, i'm saying, i can't fix that without comprise power usage when standby. i believe the kernel itself doesn't know when you are trying to play mp3 :D
[LG Optimus 2x] Leon_V6:
Is this kernel ext4 or ext3?
[LG Optimus 2x] el_liberator:
this kernel accept the both ;)

The Official MIUI is EXT3 and works fine

My MIUI Custom is EXT4 and works fine also
[LG Optimus 2x] TrZ69:
Stable and fast, i love this kernel!

SwiftExtreme-13112011HOC and nightly #200 :D
[LG Optimus 2x] simpty:
Just installted HOC-13112011 with the latest nightly #201. Now let's see, how good the battery life is ;) Try to post a report, when my 2x is fully loaded and up the night.
[LG Optimus 2x] retareq:
I second this motion. I would do it purely out of spite towards LG. We can show them how its done. I am a 3d artist so if you need a custom theme or boot animations to go with this combo kernel I'll help.
[LG Optimus 2x] ehmjay:
is there something we can do to make the wake up time ( in call & screen off) almost instant? i know it will cost battery life but it's kinda important for me.. what's the ideal frequency to make them fast?
[LG Optimus 2x] xIceCream:
Which version of MIUI should I combo with this ?

Miui US ? or MIUI HD 3.0 from german ?

Please advice + which baseband will give the best battery life ?

Thanks ~
[LG Optimus 2x] Dekudan:
I also agree. I'm wondering if these guys could take on the task of writing a .35 kernel or higher. That would really be a value add to our device. Would ensure more futureproofing.

Just going on experience, the CM devs for the ZTE Blade wrote a .35 kernel, and it significantly boosted graphics performance. Perhaps we might get some nice little benefits if we got an upgrade, too? Just a little hope here :)

Also, really loving this kernel
[LG Optimus 2x] Higgsy:
@Fajarep

Had a couple of random reboots today since installing the 13/11 kernel. Just to let you know.
[LG Optimus 2x] Harsh:
New kernel 3.x.x coming into dev community with galaxy nexus, maybe direct port to version 3.x.x would be even better
[LG Optimus 2x] Dekudan:
That's a very good point. Would just like to see it happen. I wonder if LG will stick it's leg out and actually get on with it. It's not promising because ICS can run on .29, as shown in the sdk.
[LG Optimus 2x] Higgsy:
3 random reboots so far tonight on the 13/11 MIUI 1.11.11, I think I am noticing them as I have my phone in front of me on my desk at work, and every so often I have felt the phone vibrate and when I look at the screen it is rebooting, might not have noticed in normal usage. Anyone else having this issue? even though people may not have seen it, maybe you could check "about phone" for the uptime to see if it corresponds to the last time you reboot ed your phone. Gone back to that test version fajarep put out yesterday for now as that was working nice for me.
[LG Optimus 2x] fajarep:
well, if you take a look at nvidia git, nvidia change a lot to make nvidia tegra 2 works better, perhaps for nvidia tegra 3. i believe LG really want to use that, but i think, they are some cost / benefit barrier that prevent LG rebuild optimus 2x with those new source.

may need some report about this, i don't get any random reboot while testing. i think, your handset may not support 316mhz@760mv.
[LG Optimus 2x] Higgsy:
Let me know what you need - out of interest what was the difference between that test kernel you put out on 12/11 and the current 13/11 kernel?

Cheers for replying :)
[LG Optimus 2x] fajarep:
the simple changelog :

12112011-preview -> 12112011-test

-increase ddr voltage

12112011-test -> 13112011

-lower voltage @316

-introduce second core threshold activation
[LG Optimus 2x] fajarep:
dear all,

based on my initial testing on 13112011, it's already support "guaranteed" second core turn off to extend battery life. the idea is simple, when you set cpu frequency at specific frequency, it will prevent second core being turn on because the current frequency won't break the threshold.

i'm going to test initial the code around wednesday, test it(playing games like shadow gun), and maybe an update on sunday.

in theory, it should double your screen on battery life :) but going need to test it to give initial report benefit..and test proof of concept..
[LG Optimus 2x] italoxp:
But would it make the system slower? Like sluggish transitions?
[LG Optimus 2x] fajarep:
i still don't know, because i haven't changed the code. but i'm going to make sure as normal users, won't get bad side effect... let's hope :D
[LG Optimus 2x] italoxp:
Thank you for the effort, anyway. It's pretty nice to have developers working on our device... Thank you. I really appreciate your work.
[LG Optimus 2x] retareq:
Maybe this will be of use...we found out in another thread that second core kicks in around 800mhz. So <800mhz it runs on single core.
[LG Optimus 2x] ehmjay:
the mp3 glitch is still present during screen off.. i set it to min 316mhz but still glitching.. will it change if i set min freq to a higher value?
[LG Optimus 2x] fajarep:
maybe, just try it.., but like i said, it will defeat the purpose power saving :) if you set min 316.., the frequency will float between 316-416. i can't imagine, playing mp3s need more than 416mhz???
[LG Optimus 2x] ehmjay:
after setting it to min 500mhz and still glitching.. i think maybe it's not freq related..
[LG Optimus 2x] ron_gangte:
I have no Glitches while playing music when the screen is off. :)
[LG Optimus 2x] el_liberator:
Me too , no problems with music when the sceen off
[LG Optimus 2x] mooondark:
Yep, same here. The screen goes on very quickly even when playing MP3.
[LG Optimus 2x] ehmjay:
in glitches, i intend micro pauses in the song, it's like im using a pirated cd..
[LG Optimus 2x] Gingernut78:
I've had no crashes, sod's or random reboots so far on 13112011 release just amazing battery life :eek:.

I can't have had a reboot without knowing cause my sim asks for the pin code on start.

I did notice sometimes, not always, screen on could take a few second, even if I have nothing on in the background. I can live with that if that means I get longer battery life.
[LG Optimus 2x] TrymHansen:
Try to eliminate one thing at a time.

I assume you're playing the song from the external card, so 1st try:

Copy a song or two to the internal sdcard.

Remove the external sd-card.

Play song.

If it still stutters, then, well, we're no further. If it doesn't then your sdcard is the problem.

The point is, try to change things around, one thing at a time.
[LG Optimus 2x] fajarep:
thank you all for your support..., next version going to be better in battery lifetime, and more responsive than current version. going to release preview version on friday...

i got some idea implementation and patch...
[LG Optimus 2x] ehmjay:
It has nothing to do with SD card because mp3 is working fine with stock miui kernel and stock LG kernel, fine also with spica's HP kernel
[LG Optimus 2x] fajarep:
ok :D because it seems, this is problem not happened with a lot of users, i think you should use another kernel version, not swiftextreme...
[LG Optimus 2x] jay_snake:
About the mp3 stutter problem with Poweramp, I've experienced the same thing and found a solution to it.

1. Go to Poweramps settings

2. Go to Audio Engine

3. Go to Advanced Tweaks

4. Set audio buffer size to huge

5. Set audio thread priority to +1

6. Play mp3 and turn of screen...no more stutter for me!
[LG Optimus 2x] Gingernut78:
What music player do you use? sorry if it was already stated.

Edit: OK, your using Poweramp
[LG Optimus 2x] TrymHansen:
I don't understand your argument. You are saying that because other kernels work fine with your sd-card, then this one must work fine as well.

I'm not saying your sd-card is to blame, it most likely is not, but the argument does not hold up. Did you test it? Takes a couple of minutes.
[LG Optimus 2x] ehmjay:
no i'm not.. i'm using the stock miui music player because it can be launched through lockscreen ;) (double tapping the lockscreen) .. and yes i tested playing the mp3 file from internal sd and stutter is still there..
[LG Optimus 2x] Darkje:
Is it needed to run something like SETcpu. Cause when i do and clock my device to 1.5ghz my phone is hell fast!

With SETcpu i can also make diffrent profiles withs saves me allot of battery.

After 10hours nearly 30% battery off. But i believe this should be arranged by the kernel itself. But then my bettery is empty after 10 hours :-)

Please give me your response..
[LG Optimus 2x] Shadowchaz:
I have set my screen off to use 500 - 700 MHz and overall I use about 50% battery in a day. That's average internet usage a couple ofphone calls a few texts and about 1 to 2 hours mp3 playback through power amp. I increased the screen off as I was getting some sod after calls

[LG Optimus 2x] wuffi123:
phone reboots itselfs every 2-3 minutes.

before i restored (non-system-) apps with titanium everything was fine. after restoring everything was fine to, till i rebooted the phone manually the first time...

would like to have a cm rom / swiftextrme kernel, but without apps and with reboots every 3 minutes its useless for me.

can anybody help?
[LG Optimus 2x] mr_dan:
guys... my phone freezes after calls... when the other guy hangs it, screen remains black and i have to pull out battery and hard reset... is it because of low offscreen cpu power?
[LG Optimus 2x] Shadowchaz:
I have used setcpu to increase screen off MHz seems to be OK and have not noticed any difference in battery useage
[LG Optimus 2x] mooondark:
Never had this one with SwiftExtreme but had it with Vorkkernel ... Whick ROM are you using (Stock/CM/MIUI) and which version ?
[LG Optimus 2x] orrebo:
Does the last kernel update work with miui 1.11.11?
[LG Optimus 2x] el_liberator:

[LG Optimus 2x] ehmjay:
anyone tried the ICS animations?
[LG Optimus 2x] orrebo:
Ok. Will try it out :)
[LG Optimus 2x] el_liberator:
how related to the Fajarep kernel ? :D
[LG Optimus 2x] owain94:
deleted will sent u a pm (:
[LG Optimus 2x] fajarep:
hey, thanks for the trick, it will help others that get problem :)

kernel only manage screen off/on, i believe when you set cpu, you can use setcpu to lower maximum clock at specific battery level.

that will be useless, the kernel will force floating frequency when screen off around 500-600mhz :D

if you get SOD, there is a probability your phone can't handle low voltage or frequency at screen off events, the only work around that i know, increase your lower frequency instead 216.

that's not kernel related i believe, if your phone working fine before restoring application, there must be some configuration from previus OS that mess the current OS.

good to know, sorry about that :)
[LG Optimus 2x] Shadowchaz:
Must be coincidence then that I have not had sod since raising the screen off speed if it has no effect!

Cheers for your hard work
[LG Optimus 2x] mr_dan:
i got cm7 nightly (202 i guess) with new swiftextreme kernel.. with setcpu i managed to change low frequency at 500mhz... but still i got SOD.. display is black and i gotta pull out the battery
[LG Optimus 2x] wawyed:
Same here with MIUI 1.11.11 and SwiftExtreme, going to try though increasing low frequency as he says but if it doesn't work for him...
[LG Optimus 2x] polmone:
Hai all,

in this kernel how can increase the min frequency clock and its voltage a little bit?

With Pimp my cpu i can only reduce voltage and set a default clock...

Tnx

...sorry for my english...
[LG Optimus 2x] italoxp:
To increase the minimum frequency, you long press the chosen frequency, and press Set Min. To increase voltage... Well, that's not possible. The kernel doesn't support it. I don't know any kernel for our O2X that allows overvolt, only undervolt. But why do you want to increase the voltage?

[LG Optimus 2x] magicmarkus:
Same here. Blackscreen. Only pull battery works. Can you fix this
[LG Optimus 2x] ehmjay:
hi it's me again! the one with mp3 stuttering.. i tried the following tests:

1. played mp3 with stock miui player, screen off, headsets plugged in, after 30 seconds mp3 started to stutter

2. played the same mp3 using poweramp, screen off, headsets on, mp3 still stutters

3. set poweramp audio buffer to huge, same results

4. played the same mp3 but this time i copied it to internal sd card ( as suggested by higgsy) but still same results..

im desperate, i really like your this kernel but i like music too.. can someone help me? or can anybody give me a flashable file of the stock miui 1.11.11 kernel?
[LG Optimus 2x] Shadowchaz:
Does the music stutter if you stream something different to an mp3? I use apple lossless and they play fine with the screen off. Also do you get stutter when the screen is on?
[LG Optimus 2x] ehmjay:
what's apple lossless? and nope, mp3 does not stutter on screen on, i also watch films and the audio plays fine
[LG Optimus 2x] Shadowchaz:
Uncompressed audio at CD quality. Its similar to flac. I see no reason to compress audio when I have a 32gb card.

The only other thing I can think is you have another app using CPU in the background which is why low frequency is causing you so many problems. Have you tried killing all unnecessary processes system monitors and anti virus programs?
[LG Optimus 2x] italoxp:
Try increasing the minimum frequency on Pimp My CPU, tell us if it still stutter.

Or download a song in .ogg or .alac or .flac and see if it plays well.

If the second option works, you've got a problem with your files. If the first one works, you have a bad chipset.

In my own experience, with .flac files and 320kbps mp3's, I've experienced a few issues in 1211011, but in 1311011 it's perfect. And when I say a few issues, nothing that can disturb you, just one second stutter each 40 minutes.

EDIT: As user above noticed, you can have an app working on background too. Be sure to check that. If increasing the frequency works, must be that, or a chipset problem. Check anti-virus, or a game, anything.
[LG Optimus 2x] ehmjay:
i don't have any antivirus or system monitor programs.. i have my min freq set at 500mhz.. i'll try higher freq then i will report..
[LG Optimus 2x] italoxp:
Do a Nandroid backup, wipe the data, try playing any song with the system clean. So you'll be sure that your system is clean and you have nothing disturbing the system. Or you can download a different music format and see if it works. But I really don't know what it can be. If your frequency is already set high, there must be a problem. If you're sure there's nothing running side by side with your music app and the songs aren't corrupted, I guess SwiftExtreme doesn't work for you.

Sent from my MIUI powered Optimus 2X.
[LG Optimus 2x] ehmjay:
i think i solved the problem.. i installed hoc version and set freq to 503 - 1216 .. played 4 songs without stutter now.. i will test it again tomorrow
