R: [KERNEL][CM10/CM10.1][100p2 - 2013/02/16] Kowalski Kernel - Now With Nightlies !

I'm testing exp-105 for a couple of hours ... I'm forcing with games like temple run and other applications open at once. Everything is working fine ... no problem at the moment.

Sory Pengus, I don't want to hurt you. I had a bad day (journey) and I was very bad after reading myself.

I'm sorry because in fact when trying CPU Adjuster, I missed the option to aply the settings so I thought I had to buy this app in order to make the changes. My bad...

Now that I understood a bit more on this app, and tested again, I can confirm your kernel is fantastic. :good:

I hope to meet you in order to pay you a real beer. :highfive:
[LG Optimus 2x] calav3ra_de:
Had device not wake up from screen-off on exp 105, then reboot with bootloop. I did UV, but with values as usual. Went back to exp 104, no problems so far. Have korean phone

edit: tried getting "dmesg | less" command from adb shell with su, output doesnt contain the cpu info like others have. what do i need to do to get it? fresh boot of phone to lock/sim screen, or cwm recovery?

edit2: got it by rebooting to recovery:

I am on Tonyp's PA rev6 and my phone was made in Korea.

My phone does not tolerate more than 25mV UV without completely locking up and/or bootloop if I enable set on boot. OC works well, however. It has been a couple days at max 1200 and over a day at max 1456.

Switched to exp-105 kernel a couple hours ago and video seems to be ok. My default profile is 1456 with 25mV undervolt on all "speedsteps" and everything seems ok for now.

I get Antutu scores of about 8400-8500.

EDIT: I haven't had enough idle time to know if wifi drain (stuck at 216mhz) is gone.
[LG Optimus 2x] DrummerMuppet:
Alright then, this is the info:

Device model is p990h.

Don't know if this helps, but here it goes: I was running exp4 when I flashed exp5. After that, boot would get stuck at the CM logo. Then, I decided to do a full wipe, reflash pengus' CM10 and exp5 kernel and to my surprise it booted! The bad news is that after a reboot got stuck at the CM logo again, so I'm back to exp3.

Re: [KERNEL][CM10/CM10.1][100p2 - 2013/02/16] Kowalski Kernel - Now With Nightlies !

I had this exact same problem with 103. If I turned off the screen it wouldn't come back on. Got a friend to ring me to make sure...some details:

ROM: cm10 unofficial 20130208

Kernel: kk exp 103

Min Clock: 456mhz no UV

Max: 1456mhz no UV

Scheduler: dyninteractive

Io: NOOP

SKU 15 rev A04

I went back to 102 because I need my phone working, havent tried newer expts. But I miss 60fps quadrant already :D

On a slightly off topic note, what's the story with the light sensor and HDMI screen orientation? It doesn't really matter, just curious :p
[LG Optimus 2x] Kyrandialegend:
I flashed 105 and I set :

max freq=min freq=216 MHz with default volts (775mV) and ran antutu (stability and bench) and all was fine.

max freq=min freq=312 MHz with default volts (800mV), same tests, and all was fine.

I'm sure i'm not instable at lower freqs (I have never undervolted) , even because i have no bsods at screen off with 100p2 and 011p4 (using the same default voltage up to1 GHz)

Don't know what to think :confused:
[LG Optimus 2x] hadi_rena:
I'm using 105 and work fine till now :victory:

[LG Optimus 2x] kaioder:
One question. What is this information for? And where is it?

Thanks.
[LG Optimus 2x] pengus77:
Combo Release

Ok guys this is important so read carefully:

I found an ugly bug in Faux123 code for dynamic fsync. It is disabled by default but the bug was triggered on resume no matter what. It could have been very well the root cause for the data loss reported by some people in the last few days. I'm sorry i didn't notice it when i cherry picked his code. I spent the last hour with Tonyp on gtalk discussing this and then i fixed it in code. Basically now if it's disabled (and it is by default) it doesn't lead to any problem. If it's enabled it will flush not only on suspend, but also on reboot/shutdown. So it's really safe to use now.

Again sorry if this was the cause...

Anyway, experimental change log follows:

- Fixed Faux123 Dynamic Fsync code and added reboot/shutdown forced flushing of buffers

- Fixed the dvfs code to recognize tr@p's cpu (lol he seems to be the only one with a cpu id = 0) and maybe others too

- Fixed a lot of dvfs wrong process ids that were leading to broken scaling (and possibly sleeps of death)

And here's release change log

- Fixed Faux123 Dynamic Fsync code and added reboot/shutdown forced flushing of buffers

- Added Max CPU Frequency when screen is off

- Fixed wifi suspend issues

They're already up in my xdafileserver folder both exp (106) and release (100p3).

Have fun !
[LG Optimus 2x] tr@p:
LOL, I feel so special now... xD

Thanks pengus! :)
[LG Optimus 2x] kaioder:
I have installed exp-106 and now I am getting stuck at Xperia logo. Reinstalled exp-105 and nothing. Is this data corruption?

PA 07, old bl.
[LG Optimus 2x] Kyrandialegend:
tnx pengus, i go for the nightly :D
[LG Optimus 2x] pengus77:
Unfortunately it may be :(

This kernel is mandatory in its exp or release form for everyone. IF the data loss problem is due to the old kernel code, then yeah everything before 100p3 / 106 is dangerous...
[LG Optimus 2x] kaioder:
Well, I had a backup and I restored it, so no problem but, if I reinstall 106 is sure that will be corrupted again?
[LG Optimus 2x] tonyp:
Turn the screen off and on again immediately before rebooting to recovery, this should flush the buffer correctly.

Then install 106 and you're good to go.
[LG Optimus 2x] DrummerMuppet:
Re: [KERNEL][CM10/CM10.1][100p3 - 2013/02/19] Kowalski Kernel - Now With Nightlies !

Just flashed exp6 and gotta say great job, pengus! Everything's perfect now!
[LG Optimus 2x] tr@p:
106 works like a charm here. Had a freeze, but it happened when CPU adjuster kicked in. I guess I'll need to raise voltages a bit.
[LG Optimus 2x] Kyrandialegend:
I falshed 106 on pengus's rom and all went ok. I wait and see if the sleeps of Death..died:D

Warning! Risk of data corrupt

Installed 100p3 and i got random reboot and, all data erased:(:(:(:(:eek:

ROM: Last CM10 by pengus

Kernel: 100p3

Phone: Made In Korea

Whats I doing when this happend: Installing Antutu from market, phone reboot and all is gone =/
[LG Optimus 2x] pengus77:
I suppose you haven't read the last two pages of this thread...
[LG Optimus 2x] zchuxz3x:
yes Sr! but you said "Basically now if it's disabled (and it is by default) it doesn't lead to any problem"

I dont touch anything relased with fsync, so, it is disable "by default" right? (to avoid problems) so, why i get erased Data? o.O

sorry my english, and really no is problem to get this "erased" because i make a clean installation 1hr ago xD
[LG Optimus 2x] pengus77:
You're correct. My fault. All downloads have been removed for the next few minutes. Thanks for the report :)
[LG Optimus 2x] tr@p:
Basically, you could get data corruption from previous kernel... it's not the new kernel that causes data corruption. If you have backup, do a full wipe, flash ROM, gapps, new kernel and restore backup (data).

BTW. new exp kernel should be called or at least advertised as 'smoothness reinvented'. It's thatsmooth. :)
[LG Optimus 2x] calav3ra_de:
Wondering that nobody of us european guys needs sleep. ^^ But anyways, i made it to exp 106, no sleep of death by screen whatsoever and great smoothness - apps load even faster (sms,exdialer,firefox,...) :)
[LG Optimus 2x] pengus77:
No, it slipped in a problem. I'm reuploading the kernels now. Please re-download and update as soon as i post that they're up.
[LG Optimus 2x] zchuxz3x:
so, to install 100p3 is recomended make a "clean" installation?

with olds 100p's only I make Wipe Cache, then flash kernel..
[LG Optimus 2x] pengus77:
No, you can simply flash it over.

On a side note i suggest that you all install Trickster and ENABLE dynamic fsync before rebooting to re-flash the kernel. This is needed to correctly flush the buffers and avoid data loss. This step is needed only before flashing the new fixed kernel

Experimentals are up in my xdafileserver folder and replaced the old ones. Releases are cooking now and will replace 100p3 that's been pulled from the folder.
[LG Optimus 2x] tr@p:
I guess you're fine with cache wipes, but if data corruption occur, full wipe is a way to go. BTW it's not a bad idea to do a full wipe from time to time.
[LG Optimus 2x] pengus77:
Emergency Update

Ok it's late so few people grabbed the kernels already ( i hope ). The fix for fsync was incomplete and slipped through badly... coding at 3.00 am does that... anyway both exp and release kernels have been replaced with fixed versions. Please download them and, before re-flashing, install Trickster and turn on Dynamic Fsync. this will force the bypassing of the bug and will guarantee a safe exit from the last bug.

All downloads in my xdafileserver folder as usual. Sorry for the derp.
[LG Optimus 2x] zchuxz3x:
Its ok! many thanks pengus.. and i need to make a noob question...

where is the option to enable fsync on Trickster MOD? :S i cant see it:eek:

again, THANKS YOU PENGUS! You are a good developer... and person!!
[LG Optimus 2x] pengus77:
Last page on the right, right under Force Fast Charge. Make sure you have the latest version from play store.

How come latest pengus cm 10 rom has crt effect on me? I just flashed exp106.
[LG Optimus 2x] Miwer:
Hi pengus,

What an amazing work you do on the kernel. It's been interesting the last couple of days - a lot of updates passing through :)

Last night at about 0.30 I discovered my phone had frozen while sleeping. I could feel it was warm around the camera, and I could not turn it on. I quickly reseated the battery, and booted it, and I was able to extract something from last_kmsg.txt - last entry was at 23.20

I'm still at 100p2 (PA build 7), and I wasn't sure from the last couple of pages, if your 100p3 is fixing anything related to this.
[LG Optimus 2x] pengus77:
Yes, update to 100p3. 100p2 has been pulled from the folder...
[LG Optimus 2x] Crazy32:
Hi pengus,

i tried to flash your kernel 100p3. Before flashing I had wiped cache and dalvik. After flashing the kernel I had a bootloop. Now I tried the 100p2 and the kk-exp-20130219-106-newbl, but I have always a bootloop 

im on your latest rom on the new bootloader.

Can you help me?
[LG Optimus 2x] Miwer:
Ok - will do. You state that we should enable dynamic fsync just before upgrading.

What is your recommendation of dynamic fsync after upgrading to 100p3 - leave enabled or turn off?
[LG Optimus 2x] pengus77:
Please read the last two pages of this thread. There has been a problem with data corruption and the solution is written in bold :(
[LG Optimus 2x] pengus77:
It's your choice actually. I keep it on with 106 and all is fine and fast so far. It could lead to data corruption if the phone crashes though... so it's really up to you :)
[LG Optimus 2x] FatherJony:
This is for you to judge. Leaving it on will give you a performance boost but you might get data corruption on an abnormal shutdown.

[Edit]

Lol, pengus got me once again, dude you are a machine (or maybe I am just slow :p).

AW: [KERNEL][CM10/CM10.1][100p3 - 2013/02/19] Kowalski Kernel - Now With Nightlies !

for me 106 kernel doesnt feel as snappy as 105. scrolling isnt as fast as before. antutu also states this, only 6900, before it was 8300 and now with bad scores at 2d graphics and a little in cpu integer. 105 was the snappiest for me til now (too bad there was this error :)

did you also lower 2d gpu clock?
[LG Optimus 2x] pengus77:
Nope. All is the same as in 105. Antutu is not a real benchmarking suite, it varies a lot depending on rom and apps running. Try CFBench or Quadrant for more realistic results. Just fyi i get about 4200 in quadrant and here's my antutu score on 106.

Please post here your cpu/core process id as requested for reports in the previous pages.
[LG Optimus 2x] jabooka:
Pengus,

here is my logcat from this morning. After yet another freeze aka. SOD (will report it in tonyp thread, been having them lately almost more than back in the days of first cm10 nightlyes :eek: ) and battery pull, I turn my phone on and after boot noticed that my cpu was constantly at max speed I set - 1000MHz. I'm using CPU Adjuster with profiles off, interactive and CPU set 216/1000.

ROM: PA_2.6_build_05_oldbl

Kernel: kowalski_100p2, Feb 16, 18:17:02 CET

Phone : made in Korea
[LG Optimus 2x] pengus77:

Damn - please delete....
[LG Optimus 2x] jabooka:
You have just missed it, my superb penguin genius you :)

...so, no OC, even before in exp kernels I turned my CPU to 1000MHz max. After you suggested to make a switch to release kernels I did so. Just downloaded 100p3 and flashing...drama continues, as I'm more and more tempted to either introduce my phone to the laws of physics, especially Sir Isaac Newton's 3rd law, or let it aside for a while and far from sight and revert back to Nokia 6120c :eek: ...sorry, just needed to vent my frustration that have been constant in last few days with my O2x.
[LG Optimus 2x] pengus77:
Really weird... i can understand 100p2 could be problematic for some due to the fsync bug. I suggest you do a full wipe and restore your apps and data and flash 100p3 to be on the safe side.
[LG Optimus 2x] coolacrille:
Do I have something to worry about if dmesg has hundreds and hundreds of lines saying "do we really need this big skb??" ? Does it have anything to do with my wifi disconnecting?

I'm removing the downloads for the 009p1 kernel for a few. I found a bug and need to fix it before uploading a 009p2.

I suggest that 009p1 users revert to 007 or avoid connecting the phone to usb until i upload (next few minutes) a new patched kernel.

Sorry for the inconvenience.

silly question, but the thread title says cm10/ics, does that mean stock roms ics, and cm10 only? so using optithrust with this kernel should work?
[LG Optimus 2x] lucfig:
I must say my phone never felt so smooth and stable, your work with our devices is amazing.

If/when you plan to get a new device, let us know which so we can buy it too. :D

The Interactive governor is the smoothest for me, is the DynInteractive governor more battery friendly?

Hi Pengus, do you ever sleep? Thanks for your work, LG should pay people like you for your Kernel. I installed 009p2 with psp module. If I am right it's worth testing max background procs limitting to 4 and disabling zram? I also do not use swap. For the rest I am using row / interactive cpu since last 4 versions.

@lucifg I didn't notice real battery improvroments with dyninteractive in idle mode, only when in use but it's a small difference.

[LG Optimus 2x] Platoon:
And how to disable zram?

I also have terrible problems with wifi using Django ICS. After i wake up the phone wifi usually doesnt want to connect to my Asus N16 router (with tomato). I am using G connection and I also have two other routers in my house with same SSID (one router has N speed). This is not normal behaviour. I need to press off/on once or maybe twice and then i can connect. And even then there are problems. At the beginning connection is not stable and it is reconnecting and connecting for a few seconds, then it stabilises. Wierd

Try it with app extractor.

A full wipe with restoring data is like no wipe at all.

And if your issues really are caused by corrupt data you should start over fresh and restore as less as possible.

When I do a full wipe I usually only restore sms (with sms backup+) and the Google authenticator (with titanium backup) because it's a pita to set it up.

I'm on 106 with no active profiles in CPU Adjuster (so it's as you settled it), tony's PA 08pre (this could be the problem).
[LG Optimus 2x] Dscheesix:
Hey ho penguins and friends

I´m one of the silent guys so far, so hello :D

Created my account a few days ago just to say thank you for this awesome work.

My experience so far:

I´m on tonyp and kowalski since about... tonys build 04 and kowalski 007 i think, had no problems so far, everything working fine. last config was tony 05 with 100p1 and then switched to tony 06 in the last days. still everything fine, no bootloop, no freezes, nothing. on kowalski 010 i thought it can´t get any better now, then you came up with oc - very very nice :good: :D

a few minutes ago i updated to pa build 07 and 106exp, while writing this text i got my first freeze ever on your builds. phone was in chill-modus (display off...) then display turned on and freezed. pulled battery and rebooted, now it runs well since about... 10 minutes :) if things happen again i`ll provide logs and things but for now its ok for me.

right before freeze i turned on fsync in trickster, maybe my phone crashed for this reason. I´ll leave fsync off for now and maybe try later again.

Again, thank you for your work (tonyp and pengus77). I would go for some beta testing or help you otherwise if you need "help" :) just pm

greetings

[LG Optimus 2x] optimusG:
Hmmm I think that pengus77 found out why my phone (and others ones) didn't like his latest kernels. It is very possible that sleeps of death were caused by the faulty dynamic fsync code. No problems so far with the latest exp with o/c and -25mV U/V to all freqs.
