Yes! Got it working! The last time i tried it I didn't check the execute checkboxes xD Thank you very much :)
[LG Optimus Black] CalamitySir:
Anyone noticed that the sound volume when recording video using the default camera app is very low?
[LG Optimus Black] aprold:
Started to poke around and the first thing I found was the wrong update-script which I took from test2. Sadly I didn't notice (it was too late already) that most crucial things were not in there. By bad. Will fix it in the moment. This is why you get permission denied errors and this is why the phone is slow among other things you might not have noticed yet.

EDIT: edited updater-script and re-enabled download link on the first page. This time tested it thoroughly with different scenarios which involved both updating over existing kernel and wiping everything beforehand.
[LG Optimus Black] ivanlau:
good. ...looking foward to trying ur release :)
[LG Optimus Black] naeem86:
question for the dev..since CM server is down and we are not having any nightlies since duno how many days, and this kernel is running pretty good, why do u guys look for a nightly which is quite stable and improve it?! :)
[LG Optimus Black] TheGripper:
There are still pretty important bugs to fix (video framerate,radio, volume...)
[LG Optimus Black] naeem86:
am sure they can fix them!:P and by the looks of it..these bugs won't be fix because ricardo is working on ICS!:S
[LG Optimus Black] CalamitySir:
The score I got for the newly updated kernel with rawr command....thanks aprold
[LG Optimus Black] mgregor:
So is it safe to install v8 with nightly v20 together? Or will I brick my phone? ;-)
[LG Optimus Black] CalamitySir:
i am using it now and look at my previous post...that kind of score? what do you think? to me it's perfect!:D:D:D
[LG Optimus Black] aprold:
Nightlies are nightlies. You can never presume everything works there. People who use nightlies are crash test dummies. And most of us are quite happy and willing to be so. I've tried almost every nightly version myself and at the beginning I wished there was a hard reset button because yanking out the battery on regular basis was simply too troublesome. Later I was already able to do this in couple of seconds ;) Newer nightlies might introduce several new issues but general trend is always for better - there has been no yanking for a long time already.

Crash test dummy should not be afraid of what might happen. **** happens and if it happens just get yourself back up and try again. You'll learn few new things in the progress and if you want to be really-really helpful then you'll stick your nose into it again and try to reproduce the problem to understand why this happened and report it back here or there with as much specific information as possible.

The biggest problem we have here is the fact that we have 2 uncertainties here: CM itself and Nova kernel. It's very hard to tell which one is the culprit and where to start debugging.

Long story short: please try it and let us know how it went.
[LG Optimus Black] mgregor:
So... Installed. First run after update was a little long (3 min) and I was thinking that I have bootloop. But wait a little long and phone starts normally.

I know I'm a crash test dummy ;-)
[LG Optimus Black] TheGripper:
Stuck at 1ghz all the time...solution anyone ?
[LG Optimus Black] masterthor:
Afaik, there isn't a solution other than downgrading to V7, however, the previous few pages were mentioning that this might in fact be a "display bug". Unfortunately, this bug appears to be found in all applications that monitor CPU speed, so I'm not entirely convinced that this is just a display bug. Furthermore, I have noticed more aggressive battery usage using V8 (so I switched back to 7), and other people seem to be getting the battery drain as well, so this might be in fact an actual bug introduced in V8. Can anyone confirm?
[LG Optimus Black] dharmabm:
Running cm7-17 with knzo-v8 (updated by aprold) - CPU appears to be stuck on 1000 but in time shows valid values. I think the problem is with cpuspy not lionheart
[LG Optimus Black] neeewwww:
Using Nightly #20 + aprold #08 kernel.

Wipe Dalvik cache between installations...

Got a huge battery drain during the dawn (No usage - From 100% to around 30% in 4hrs)

The cellphone keeps at 1Ghz and awake while its recharging through USB.

CPU Spy and Sey CPU says its stuck at 1Ghz

PowerTutor says low power usage by the CPU.

But the drain curve showed by the Battery Status is true... The consumption is more agressive than with the #07
[LG Optimus Black] lvlouro:
Personally I don't experience this problem, my battery lasts longer now...

And on spy cpu I have almost no time at all at 1Ghz.

this night while charging it stayed on 1Ghz but right now I'm charging and it reads 300Mhz all the time...
[LG Optimus Black] lesp4ul:
Yeap i compared with nexus one cm7 with wildmonks kernel running smartass v2 gov, min 245MHz max 1152. OBlack CM7 #20 nova8 smartassv2 min 300 max 1000.

Both are clean install with cpuspy installed (no network data activated) and the results was: n1 only drop 1% idle and oblack lost 9% in half hour. And yes oblack stuck at 1GHz at most, deep sleep worked but the clock jumped from 300 to 1000, no 600 and 800.
[LG Optimus Black] vmjoaquim:
Hmmm, I don't have any battery issues. Though I have the CPU stuck at 1000Mhz when plugged in USB problem. When the screen is left on, the phone takes painfully long to charge. To put it in perspective, it takes more than 10 mins to up a single %. However, when the screen is off, charging resumes as per normal. Evidence of CPU lock I guess? :/

But Aprold did mention that some scripts were wrong? Could any of these issues be caused by that?
[LG Optimus Black] knzo:
What? 9% - 30 minutes?

Get BetterBatteryStats (free on XDA) and try to see what's doing that.

For my battery studies I use the following combo:

Juice Plotter

PowerTutor

BetterBatteryStats

CPU Spy
[LG Optimus Black] dataDave:
Hmmm... Not too good, after a couple of days she asks me why some of her apps have disappeared (namely all the ones migrated to the SD card) I do a check and notice that the SD card isn't mounted for some reason, so I go ahead and try to mount it but it won't recognise anything in the slot. So I took the card out and tried to hook it up to the PC and still no dice... all the ROM backups were on that card too. >_< 1x fried 16gb card.

I **** my pants and decide to try and mount another card just so that I can perform a backup and transfer it to the PC ASAP... but it doesn't want to mount any cards (just keeps repeating "safe to remove card" whenever I try), even from within CWM recovery mode (just says "Error mounting card!").

I'm a bit stuck now, I can't flash anything in this state and we're stuck with on-board storage that can only be written to from within the phone... and I don't feel safe wiping/factory resetting anything in case the SD reader is dead.
[LG Optimus Black] gabwerkz:
I disabled DVFS just now, as per CPU Spy and SetCPU scalings, it scales 600 and 800 when opening an app, and being 300 most of the time. I'll let you know after an hour benchmarking and putting it in deep sleep if it solves the issues.

After benchmarking Quadrant and Wi-fi ON, and trying to capture scaling, 2% in 12mins. Will monitor scaling for a longer time...
[LG Optimus Black] lvlouro:
I've experienced something today that I had already with #20 + nightly07

The phone was in deep sleep and when I turned on the screen everything was super slow and FCs started, adw, phone... had to reboot, even the reboot menu took aloooooong time to appear.

I believe It never happened with cm#20 with stock kernel...

Anyone else?
[LG Optimus Black] gabwerkz:
If you're coming from Nova v08 downgrading to v07, flash first the Nightly #20 (no wipe)(or wipe dalvik and rebuild it again at boot) then Nova v07. See if it happens again..
[LG Optimus Black] lvlouro:
It happened before I installed v08
[LG Optimus Black] Felsar:
I've never tried n20 stock kernel, but now I'm using nova08 and it happens to me sometimes, it's not that often actually it happens just a couple of times when [after the very first reboot after flash] opening the app drawer crashed and had to reboot, the second time was the first time opening market it crashed as well and had to reboot, but after those 2 times it never crash again but yeah sometimes when waking up is kinda slow
[LG Optimus Black] knzo:
Aprold I updated the dropbox.
[LG Optimus Black] ajcantonio:
how do you do that adb remount?

terminal just gives me permission denied every time...
[LG Optimus Black] :
On your computer. Must find an adb.exe or install android SDK.
[LG Optimus Black] knzo:
It needs "su" command before
[LG Optimus Black] ajcantonio:
it just says permission denied after su... root really is gone...

however, i can still choose from the added governors and set them on reboot through cyanogenmod settings > performance... rom manager still works.. there's the superuser icon but there's no root access...
[LG Optimus Black] knzo:
Ah indeed, adb then.
[LG Optimus Black] fatcobrah:
Any news abt cm?
[LG Optimus Black] ajcantonio:
can this be fixed, knzo?

the features of your kernel are awesome, no doubt... 100% worth flashing. it even makes the cm7 early release usable and somewhat reliable for daily use. the only thing is that we lose root access with it...

Why Spirit fm radio no sound on this rom ?

What fm radio app that running well on this rom?
[LG Optimus Black] ajcantonio:
i finally figured out how to do it... and it worked! thanks a lot! :)

EDIT: i rebooted and root access denied again... it's like tethered jailbreak on iphone...
[LG Optimus Black] lesp4ul:
It must be the script or other file inside knzo kernel. Some lines must be fixed, because init.d and other connected thing automatically recalled on boot. Sorry i don't know the right word for that :p
[LG Optimus Black] :
Yep. Great work from knzo once again. Maybe it's pointless but on my phone, flashing his kernel seems to make the first reboot fail... I got straight to recovery again (cm7 feature?) and then, working, but unrooted... Seems like on some phones some install scripts do not work... Remount fixes till reboot... Weird.
[LG Optimus Black] sacman74:
What's up with knzo????
[LG Optimus Black] redy2006:
He has another live outside, so don't bother asking where he is right now... He still continue it's development, while waiting for official GingerBread from LG.

CMIIW.
[LG Optimus Black] knzo:
I'm sorry to say this but I won't be having time for development anytime soon.
[LG Optimus Black] Huexxx:
Opps...

Bad news then... I hope you can give us your knowledge before that...

Thanks for what you've done in the past!
[LG Optimus Black] redy2006:
Wow, and that's really a bad news.. but it's okay, there will be another developers that will continue your work, for example Huexxx :D

But it's fine for us if you're busy with the real life outside. I believe that you still had your time to continue your hobby as a developers for later, not "anytime soon" ;)

Thanks...
[LG Optimus Black] gabwerkz:
Original v08, eRecovery removed, LG DVFS disabled, Lionheart. Battery consumption. I can safely say I'm not stuck at 1000mhz comparing to 9%@30mins (idle) and 30%@4hours (no usage) from 100% batt.
[LG Optimus Black] lesp4ul:
Hmm i just looked at battery info on notification bar and use cpuspy to check cpu history.

Okay i'll try that later. Thnx mate :)
[LG Optimus Black] aprold:
Stuck on 1 GHz state

I must say that I've never had my phone stuck at 1000 MHz for no apparent reason. Until now. I had my phone on battery for last 15 hours since yesterday evening and battery level had dropped to 80%. IMHO this is as it should be. But now I wanted to see what are you guys exactly talking about and installed SetCPU, CPU Spy and BetterBatteryStats (isn't it strange I didn't have these already?) to see more specifically what's going on. And what I see? According to SetCPU the phone sits explicitly at the highest CPU state and no matter what I try it stays there and only there. Well, now I have to understand why... I'll get back to you as soon as it hits me.
[LG Optimus Black] gabwerkz:
15hours with 80% left? In deep sleep or with some usage?
[LG Optimus Black] aprold:
Light usage in the evening and in the morning, deep sleep through the night. Both me and the phone ;)

I played around with enabling/disabling different CPU governors in the kernel and every kernel version built still had the same CPU clock stuck problem. I can confirm that original CM kernel built with default configuration didn't behave like that. This was all done during the day at the office when I had a small chance to let my thoughts do a sidestep towards this problem. Later tonight I'll do a meld between CM and Nova kernels, learn the differences and hopefully see what's wrong.
[LG Optimus Black] knzo:
That's weird because as far as I remember I didn't change any stuff aside the jHash and the governor.

Anyway, I have updated the dropbox again with a few more things I find interesting.

I've also uploaded a new toolchain that you must try.
[LG Optimus Black] lesp4ul:
I confused also, v8 governors always stuck at 1ghz. I decided to revert back to v7 smartassv2.

It gives me a better result. 90% for 2.5 hours, mostly in idle, but i must say with smartassv2 the clock often jump to 800 & 1000 in idle state instead of 300 and 600. Compared with Nexus one it can stays in 245 for long period, jump 500, 800, 1152 sometimes. Hmm.... i just curious.

This is from a moment ago using v7
[LG Optimus Black] gabwerkz:
V08

Upon opening sys/devices/system/cpu/cpu0/cpufreq/turn_on_lg_dvfs, the default value I see is 1 (enabled). Changing it to 0 (disabled) will result in proper scaling of frequencies.

Kindly check it and init.rc. init.rc has a default value of 1. I was disabling it rather than enabling (what I thought).

Under:

on property:dev.bootcomplete=1

Says:

write /sys/devices/system/cpu/cpu0/cpufreq/turn_on_lg_dvfs 1
[LG Optimus Black] Huexxx:
This is the reason why I've disabled it from V3 version of my kernel.

Regards.

---------- Post added at 07:13 PM ---------- Previous post was at 07:10 PM ----------

aprold, with your zImage injector method, you don't modify ramdisk, so init.rc it's unchanged and at stock ROM it loads DVFS at startup, generating the scaling issues (or the scaling statistics issue).

Regards.
[LG Optimus Black] Monkey101:
I too have my phone stuck at 1000mhz. Since flashing Nova v08 with Nightly #20 this morning CPU Spy reports 100% usage at 1000mhz. Battery died in 9 hours while the phone was idle for all 9 of those hours.
[LG Optimus Black] McRIP:
since monday i use the v08 kernel and i haven´t get any cpu bug report only the typical CM sound problems:mad:.

i tested for few days different different version´s of (CFS) &(BFS) kernels and have to say lazy and lionhart the are WOW! for me quiet perfect.

For now i continue with nightly #18 until servers are back, as i know #20 is more bugy

one strange thing is that i allways get better 3d quadrant scores using (BFS) kernel, about 10 frames more in corridor and DNA test, as you can see on de screenshots each best score #18 with v06(BFS) and v08(CFS) .
[LG Optimus Black] lesp4ul:
So i just need to edit that line then the prob is gone right?
[LG Optimus Black] gabwerkz:
Yes, the effect is instant, no reboot needed (just to try). Go to the direct path instead and not init.rc. Cause once you rebooted, it will go back to 1 (enabled) since it is enabled in init.rc. You need a script (init.d) that will disable it at boot.
[LG Optimus Black] aprold:
Thanks for the tip! The problem was that 08Dfvs script Knzo had in init.d directory was there just for solving this problem and I was not suspecting it didn't work. And the reason it didn't work is because sysinit is called before this property is written in init.rc. I spent several hours to find a way to overcome this without modifying ramdisk but didn't find a satisfying solution yet. There was no start-stop-daemon to execute my own script later on boot. Also, toolbox's start command didn't work as expected.

Right now I found only one way to do this without touching ramdisk. Although /system/etc/init.local.rc is imported earlier in init.rc, commands written there seem to override the commands in init.rc. Why, I don't understand yet. I don't like this "solution" because I have to consider the existing commands when adding my own.

So, how should I solve this? Is there a way to start a service inside my init.d script so I can execute my overriding script after init.rc is finished and avoid ramdisk modifications this way? Or should I still start making my own ramdisk as well?
[LG Optimus Black] aprold:
This will not work, because right now sysinit executes init.d scripts before turn_on_lg_dvfs property is set to 1 in init.rc
[LG Optimus Black] gabwerkz:
EDIT: Sorry, did't saw there was already a new script inside 08Dvfs.
[LG Optimus Black] knzo:
Ah true.

If the write is before sysinit, then just edit the script to disable dvfs unless there's a file to leave it on ("fixmyradio"). It's what I would do.
[LG Optimus Black] aprold:
The problem is that write happens after sysinit.
[LG Optimus Black] knzo:
Yeah, DVFS is what seems to be f*cking up v08's performance.

Since I don't have the device I couldn't check if my DVFS script was disabling it (apparently it wasn't), thus the CPU scaling issues.

Anyway, me and Aprold already found out how to disable it without messing with the ramdisk. We're now working on Nova v09.

P.S. I just managed to remove 300 kb of crap from the last Nova v08: "-rwxr-xr-x 1 msk msk 2.0M 2011-11-27 17:40 zImage".

Nova kernel v09 uploaded

Nova kernel v09 is up. Gotta run now, I'll write a little bit longer about the process later in the evening.

kernel:
- Built with Mjolnir toolchain
- Removed some more unnecessary things
- Switched slab allocator to an optimized SLUB
- Heavily optimized Ondemand and Interactive governors
- A few tweaks to Lionheart governor
- New iface_stat module to monitor persistent network stats
- Added option to use new global workqueue
- Disabled AUFS, Ext2 and Ext3 filesystems
- Added Quota2 netfilter and enabled it
- A few TCP values tweaking
- NFS module now available
- Add a runtime option to disable sync feature
- Raised RCU boost PRIO
- Many, many, many stability patches

package:
- Improved updater-script so it wipes cache and dalvik-cache (the first boot will be slightly longer but avoids problems)
- Added Nova settings interface (run in terminal: nova)
- Rewritten Nova init.d to support the settins interface
- Added an updated busybox
- Added auto-root restore
- Fixed DVFS disabler
- Removed libsqlite.so

EDIT: Promised to give you more detailed description but Knzo kindly explained everything very thoroughly and it would have been really hard for me to do as good as Knzo did.
[LG Optimus Black] ivanlau:
excited to test ur first release:)

I have just flashed Nova v9..:)

first impression. ..really smooth!!

trying the Nova script and testing the battery life...

thx for ur hard job:)
[LG Optimus Black] gabwerkz:

EDIT: Auto-root
[LG Optimus Black] ivanlau:
not meeting this problem..

try to reflash cm7 together with this kernel again: )..
[LG Optimus Black] gabwerkz:
I did, and it's fine now. See knzo's post (2. package)
[LG Optimus Black] dataDave:
Could this potentially fix the 'muted call until loud-speaker is toggled' problem my GF is having with her handset? I just flashed Huexxx's kernel earlier for her this evening and will run it for a couple of days before trying this update.
[LG Optimus Black] redy2006:
Question, flashing this kernel automatically wipe cache/dalvik? What about data, still remain there, or it also auto wiped?

Thanks.
[LG Optimus Black] neeewwww:
As I see... The data stills.

(Just flashed now).
[LG Optimus Black] s4pt4:
Better to backup the data first:D
[LG Optimus Black] masterthor:
That is not true. AFAIK, removing the cache partition and the dalvik cache will not cause you to lose any data (or anything on the data partition).
[LG Optimus Black] s4pt4:
Thank You Sir:)
[LG Optimus Black] knzo:
Applications data are in /data/-application name-.

Cache is in /cache/. Dalvik-cache is in /data/dalvik-cache/.

So, wiping cache and dalvik-cache will not touch your data.

Here's a quick definition for dalvik-cache by Cyanogen himself:

The long boot is because it needs to rebuild dalvik-cache. This helps to prevent problems.
[LG Optimus Black] agligoros:
this version of kernel has overclock for the cpu?
[LG Optimus Black] t0g3:
speaking about wiping dalvik cache, I found this ;)

[LG Optimus Black] Jenich:
wow..gabwerkz , could you share your config and the tweaks you use? I cant get above 2400... thx a lot and sorry for OT

to the topic: after disabling DVFS no bugs so far (I had problems with wifi before), thx for this.
[LG Optimus Black] interdan:
I think that v8 is a little unstable and sometimes had sudden consumption of battery... this kernel is more stable ??? I'm very interesting about battery... anyway I'll try very soon, the Nova package seems very interesting ;)
[LG Optimus Black] knzo:
v08 performance and battery problems (because of DVFS) were fixed.
[LG Optimus Black] interdan:
This is a really GOOD NEWS :D thx
[LG Optimus Black] aprold:
not yet, still working on it
[LG Optimus Black] lesp4ul:
In previous post knzo said about a radio tweak, is the tweak fixes sudden signal lost while using data connection?

Does dalvik automatically wiped because this is a different build to avoid problems huh? Me too always wipe dalvik before switching rom or kernel.
[LG Optimus Black] purewater:
sudden signal lost while using data connection +1
[LG Optimus Black] gabwerkz:
Here's a small recap of my battery with v09. I decided to start with 100% after tinkering it and benching. Mostly idle, no wifi/data, and lite use.
[LG Optimus Black] evilenter:
Me, too.

and sometimes I can't start a phone call while mobile data is on.

-----edit-----

but performance and battery life are INCREDIBLE!!!
[LG Optimus Black] CalamitySir:
v09 works really well for mine! everything's fine!
[LG Optimus Black] ivanlau:
after using v9 for 1 day...

i can say,the battery performance improved:)

but I get 1 issue, sometime the phone will freeze up when I was using it, most likely using whatsapp or surfing the net..

this happened twice today....

it should not be my own problem as it never happened before flashing v9....

is anyone facing this problem?

thank you:)
[LG Optimus Black] agent205:
it happens to me too,but when i'm at #17 + v7 of this kernel :D
[LG Optimus Black] t0g3:
it happend to me too with all nova kernel CFS version that I tried (from nova v04 to v09)

it happened randomly, sometimes when I using it (wake) and sometimes when I dont (sleep)

when it happened, my OBlack became hot and cant wake it up, had to remove the battery.

The battery drain realy fast while it freeze. I make screenshot below a few hour after it happed.

left image nova v08, right image nova v09 (both with ngihtly #19)

oddly, I never face that issue when using nova BFS version (v04, v05, v06)

dont know why (or it's just a coincidence :confused:)
