wiped all (i always wipe all)

if in the script there are "for command " in no way my phone boot... hangs on LG splash screen.

i don't know why... i just deleted all "for commands" line in you initd scripts and phone boots normally... this is very strange..

i can reproduce this with Juwe11's script too... with for noway to pass lg splash screen. without for boots normally... :confused:

now is 2h with your latest kernel no problem... no freeze, no bsod just smooth ..
[LG Optimus 2x] SetiroN:
I see...

well, I'll make it "stupid" :)
[LG Optimus 2x] Convel:
After installing the kernel my phone simply turns off after the boot animation. The real problem is when I try to replace the kernel by reinstalling the latest nightly; the xda-developers boot animation is still there and my phone won't get past it (the boot animation goes on forever). Any way to restore my phone without losing all my data?
[LG Optimus 2x] ragiut1:
i could be wrong, but SOD seems to happen when DPI is changed
[LG Optimus 2x] ron_gangte:
Just flashed ironkrnL00-20111207h1236.

Did not follow the prescribed procedure, yet everything seems to work fine. Haven't had any BSODs either. :-)

Looks much smoother than SwiftKernel. Gotta see if it is just as stable or not.

Keep up the good work!

PS : How can I change the bootanimation?? I'd like to have the freedom to change the bootanimation to anything I want. :-\

PPS : And yeah.. "Tasker" works like it should, though it does not work with the KANG kernels based on the .49 kernels. I wonder how you made that happen, but however you did it - thanks!! :-)
[LG Optimus 2x] ron_gangte:
Nevermind. Found out how to change the bootanimation!

Thanks for the kernel!!

Will report if I have any stability issues.
[LG Optimus 2x] ron_gangte:
Just had a BSOD while phone was idle.

So switched back to SwiftKernel.

Also, with this kernel, the "GO SMS Pro" Security Lock failed to work.

Hope this Kernel delivers both stability and performance in future.

I appreciate your hardwork!

Sorry for flooding the thread with my posts.
[LG Optimus 2x] Convel:
It doesn't really seem like a 'normal' SOD, but thanks anyway. I should probably mention that I have flashed an earlier version of the kernel before, had the same problem with the kernel itself, but was able to go back to another kernel without any problems. Back then I was using the standard cm kernel since morfic stopped updating his Trinity kernel, and I've had issues with the newer vorkKernel versions. This time around I came from SwiftExtreme, not that it should really matter since I always format both /system, /cache and wipe the dalvik cache before flashing something. What seems very strange is the fact that the boot animation in this kernel doesn't get replaced with the standard cm one when flashing back to my previous setup.

Working compo with ironkrnL

Hello!

Just wanted to report my good running compo...

I use koboltzz KANG Version from Dec 5th(http://bit.ly/sbUogR) and the ironkrnL00-20111206h0700 and didn't have SOD/BSOD since.

I got bootloop one 1st boot - but after pulling the battery - the system booted and everything seems fine now and working well. :)

I followed all steps from the 1st post.

I use RIL/baseband 0622 from Euro Open 10c.

BTW: The kernel is not working so well with Rusty KANG from Dec 7th (got problems taking calls - phone got laggy) - while it worked with the KANG from Dec 1st. Don't know why.

Keep up the good work! :)

Greetings

Medizinmann
[LG Optimus 2x] vadonka:
Good morning guys!

Last day results:

temasek latest kang ROM, bb824, ironkernel 32m version working perfect, no freeze or else, battery life is great too.
[LG Optimus 2x] Convel:
Does this kernel include som unusual data? Something that wouldn't get replaced by flashing another kernel over it? Oh, and when I enable signature checking in clockworkmod, it fails to flash. Could it just be a bad download?
[LG Optimus 2x] SetiroN:
I've made a completely new, very streamlined kernel that is as close to stock CM as possible: just the most fundamental additions (oc/uv, ramhack etc) are included. You can check out the specifics in the commits of the "streamlined" branch on my github.

It can only be just as stable as stock CM, so any issues you might have with this must be related to something else (unstable OC/UV, bad scripts, bad rom, corrupt app data); let me know how it fares speed and smoothness wise.

The build also includes my late install script changes, which include better implemented build.prop optimizations, new and improved system values applied via init scripts (now all manually applied instead of relying on the "for x ... do" scripts that some ROMs don't like) that focus on interactivity (throughput and bench scores will go down-who cares), new hosts file, root browser developer full version unlocker.

A more complete and optimized build will come in the future, for now I only needed to get something out for the (minority of?) people that had instabilities with the Dec 7 kernel.
[LG Optimus 2x] miina_tokiha:
so, for who find the Dec 7 kernel stable don't need to update?
[LG Optimus 2x] SetiroN:
Yeah, wait for the next release.

streamlined build updated, reverted the infamous CM commit that strides with OC/UV code causing call issues.

See what happens keeping close to stock? :D

[LG Optimus 2x] lucfig:
I won´t try it now. The new CM7 kernel (from kangs) makes Tasker to force close. Will test tomorow when I will have more time.(if I do not get too drunk!) SATURDAY!! XD

I do prefer closer to stock! Keep it going.
[LG Optimus 2x] vadonka:
scheduler param set to bfq its doing nothing im think. i cant see any difference.

by the way only mmcblk0 and mmcblk1 has the values anyway, all other zram, loop, dm cant change this value, so im think its pointless

/sys/kernel/debug/sched_features dont understand the NO_NORMALIZED_SLEEPER, so its pointless too.

/sys/block/mmcblk0/queue/iosched/group_isolation and /sys/block/mmcblk1/queue/iosched/fifo_batch also cant change anything

updating my mixed init script, removing useless stuff, working perfect with this kernel (32m version give me 190mb free ram, running some weather app, and others in background)

phone is fast and stable.
[LG Optimus 2x] Convel:
Thanks for all your efforts(!!!), but it still doesn't work. Did a factory reset and all. First boot after flashing it gets stuck at the second LG logo. After that I have to pull out the battery and wipe the dalvik cache. Second time it boots and all, but after mere seconds into the OS it reboots and gets a SOD shortly after getting into the OS again. Perhaps my phone simply won't play along nicely with the UV/OC performed. :rolleyes:
[LG Optimus 2x] carvajaljn:
i install the new version (00) and my phone is unrooted. I changue kernel and still unrooted (swifthxtreme).

how can i root again¿?
[LG Optimus 2x] baliriot:
try restore nandroid(if have)... or flash su zip through recovery...;)
[LG Optimus 2x] miina_tokiha:
reflash CM7 Ninghty (or KANG).

then reflash your fav kernel (if needed)
[LG Optimus 2x] limkoksoon:
i had 1 problem flashing this kernel to CM-7 nightly #204 with 0823 BB and 0208 RIL.

auto shutdown or death screen. can anyone help?
[LG Optimus 2x] SetiroN:
"this kernel". Out of 60 files available for download.

Just like when my girlfriend says "it's in the drawer".

I guess you didn't try the latest streamlined build... and you're not giving any useable information to understand what happens...

Anyway, another complete rebase is on the way (actually it's done, compiling right now, waiting for some preliminary testing before release, which probably means late evening as I'm kinda busy).

Scratch the previous one, this is the rebase as-it-was-supposed-to-be from the beginning, aimed at providing beneficial stuff leaving out unimportant stuff that doesn't even seem to make a difference. Let's call it rebaseV2

A more streamlined version will also still be available for now, waiting to eventually find the culprit for all those issues some people have.

Vadonka: yeah only now that I reorganized them I went through those script, until now I just assumed they were fine considering how widespread their use was. I couldn't be more wrong... 4KiB readahead on 200MiB-2GiB flash drives, ROTFL.

A lot of values were already hardcoded into the kernel, some more where pointless or non-existant on our ROM/Kernel version.

What will be included from now on is all very optimized and I strongly suggest not to change anything unless you really know what you're doing. Plain throughput will go down a bit, but it's completely pointless in randomly accessed partitions: what matters are IOPS, and those increase considerably.
[LG Optimus 2x] Thief777:
SetiroN As far as critical if I update the kernel with only cleaning davlika cache + cache??
[LG Optimus 2x] drigerott:
SetiroN with 00 streamlined version is very fast.. but after sometimes.. bsod... cm7kang and with miui 9.12
[LG Optimus 2x] ragiut1:
Same for me
[LG Optimus 2x] miina_tokiha:
yes, you just need to clean cache & dalvik cache.
[LG Optimus 2x] SetiroN:
Wild guess: you didn't properly setup oc/uv. :rolleyes:
[LG Optimus 2x] andy010101:
i found the december 2nd release to be the smoothest

[LG Optimus 2x] miina_tokiha:
update:

I just purchased a 3rd party battery:

using Dec 7 kernel, restart & SOD problem came back.

I don't know why, maybe because of the non-stock batt voltage.

now trying to roll back to Dec 2 v3 kernel.

and I agree with andy010101, compared to Dec 7, the Dec 2 v3 kernel feels smoother.

will report back later.
[LG Optimus 2x] norbee007:
OFF: I have exactly the same and it is no better than the stock...it's just a rip off :S /OFF
[LG Optimus 2x] limkoksoon:
nobody seem to help.. sigh
[LG Optimus 2x] miina_tokiha:
update:

I like Dec 2 v3 better than Dec 7 kernel.

it's more stable (note: I even can uv it 25mv on each step).

yes, this kernel is not perfect yet.

which one you used?

(please be more specific so we can help you)

for me, the 64 hack Dec 2 v3 is the best so far.
[LG Optimus 2x] ragiut1:
Could u post the link for the 64 hack Dec 2 v3

i cant seem to find it

thnx
[LG Optimus 2x] miina_tokiha:
looks like SetiroN erased it.

here use mine: http://dl.dropbox.com/u/39242124/ironkrnL64-20111202h23v3.zip

currently testing ironkrnL64s-20111209h2129 — streamlined built.

I'll post my impressions compared to Dec2 v3 ver later.
[LG Optimus 2x] mind_challenge:
Do I really have to wipe everything before installing this kernel and then install again?

edit: Nope, just cache and dalvik cache
[LG Optimus 2x] grognaz:
hm i tested the streamlines and my device constantly reboots with them or gets a bsod. strange...

is there any undervolting in the s versions? because i know my device doesnt like that at all...
[LG Optimus 2x] limkoksoon:
been using ironkrnL96-20111207h1236

so whcih 1 should i choose? can it be use with miui?
[LG Optimus 2x] miina_tokiha:
the Dec 7 built is not perfectly stable yet as far as I tested it.

plus you used the heavily hacked 96mb (unstable) ver.

64mb is the sweet spot for me.

so try the Dec 2 v3 built I posted above.

or the Dec 9 built (so far, this is stable on my phone).

use different ramhack ver if the 96mb not work for you.

my recommendation is the 64mb ver (if you don't use 1080p recording).

theoretically, this kernel should work with MIUI also (untested yet).

but I like CM better.
[LG Optimus 2x] vadonka:
i purchase this third party battery. its truly much more powerfull than a stock battery:
[LG Optimus 2x] limkoksoon:
thanks for the advise. i'm trying miui 1.12.9 with your dec 2 ironkrnl tonight. will report if anythg goes wrong. hope all goes well.
[LG Optimus 2x] grognaz:
you have a link where to buy this?
[LG Optimus 2x] SetiroN:
I really haven't had time to do anything at the pc, new builds have been ready for a while but I didn't get the chance to U/L. Will do asap.
[LG Optimus 2x] miina_tokiha:
http://www.ebay.com/itm/MUGEN-POWER...704598?pt=PDA_Accessories&hash=item2569cb0c56

US $43.95

too expensive with slightly more mAH.

* sorry, a bit out of topic.

but testing various battery also test for kernel stability.
[LG Optimus 2x] Medizinmann:
Hello!

Update!

Had a crash again with the ironkrnL00-20111206h0700 - no SOD or BSOD but the Phone got unresponsive when disabling WLAN or/and enabling GPS…:(

I changed to the streamline Version and the instability went away…:)

Changed to Baseband 0823 – gives me better signal indoors – battery life with 0622 was better, but better signal is more important to me.

About this OT subject spare/non stock battery:

AFAIK is more than something around 1900mAh impossible without a really bigger battery.

..i.e. like this one with 3500mAh…

http://www.obostore.com/3500mah-extended-battery-for-lg-optimus-2x-p-1327.html

…but this needs a different/new back cover.

I use this an Andida spare battery - which brings a marginal better performance – but it isn’t expensive.

[LG Optimus 2x] miina_tokiha:
update:

I like the Dec 9 kernel better than all previous ones.

as stable as Dec 2 v3 built, but sometimes it still restart (roughly once a day) when opening Dolphin Browser.

no kind of restart, SOD, or any kind of instabilities when using Dec 9 kernel.

there are some kind of memory leak.

after 24h of usage, free RAM is less & lesser overtime.

not a big issue, I just need to restart manually.

I hope you can fix this issue in later built.

thanks.

not me.

even original battery from ebay is not $40.
[LG Optimus 2x] vadonka:
i dont trust in cheap battery, i have many bad experience...
[LG Optimus 2x] SetiroN:
Came home for a shower, uploading the files now. I don't really remember which one is the streamlined build, just making a guess... test. Yeah, they're from two days ago, I've stayed at my gf's, sorry.

I've set up the PC to create new builds on my dropbox, so that I can upload from anywhere; it's building the same thing as two days ago right now, with the only difference being a version marker.

As usual, wait for files being 3min old.
[LG Optimus 2x] SetiroN:
(I hadn't tried the last build myself and I gotta say... it's faster than I thought LOL)

By the way, the normal build should be very stable as well. It also got rid of many amenities we didn't really need. I'm really impressed at how it manages heavy LWP, can finally enjoy my new ChristmasHD :D

well, i was there when a cheap battery exploded while charging :)
[LG Optimus 2x] ragiut1:
I used to have SODs all the time, except the DEC 10th version, it's fast and stable, but a memory leak is apparent.

SetiroN, whatever u did, it worked, maybe bcoz u raised the voltage a little

is it possible to implement "Time in state" feature so CPU SPY can be used?

many thnx

It's really fast and i flashed this one with 36% battery, when my device

wake me this mornin i still had 25%, since i flashed this one i have made som calls, some market updates, send some SMS and read Twitter/FB, used google Maps

Wifi always on

[LG Optimus 2x] vadonka:
chainfire3d is a tweaked graphics driver, it is faster than the stock kernel driver for tegra. the option that emulate qualcomm and powervr is just a side effect :)
[LG Optimus 2x] miina_tokiha:
just try it.

it's free.

not just for games.

home screen & app drawer feels smoother when using Chainfire3D OpenGL driver.
[LG Optimus 2x] ron_gangte:
Can you please guide me a lil' on how to use it...? :-)

I mean.. I installed the Chainfire3D Drivers.. do I now need to install other shaders or plugins? :-\
[LG Optimus 2x] miina_tokiha:
no need.

I just add the "Unroll textures" options.

the rest is good enough.

except you want to Reduce texture quality & Reduce texture size.

this options can boost benchmark scores, but can make your device unstable.
[LG Optimus 2x] SetiroN:
Yeah, to test whether or not it was the cause of an annoying bug

I've sometimes experienced creaks coming out of the speaker right after boot, paired with a huge system slowdown, only solvable by killing every single process/service. Still have to confirm whether it actually was voodoo or some buggy app.

Elaborate.

Time in state=no can do.

The best thing it does is that you can force 16bit textures and compress them, making bigger ramhacks compatible with more games.
[LG Optimus 2x] vadonka:
hi SetiroN

i found that this settings below will provide better battery life:

/proc/sys/vm/swappiness = 60

/proc/sys/vm/vfs_cache_pressure = 200

/proc/sys/vm/dirty_ratio = 50
[LG Optimus 2x] ron_gangte:
How stable is the latest release? Which one is better - the streamlined one or the regular one?

Thinking of flashing it. But then, I'd wanna know what others think about the latest kernel.
[LG Optimus 2x] xIceCream:
Mind to explain what they do ?

Mayb I can even set them to lower / higher if I don't need those.
[LG Optimus 2x] Barnabe619:
I searched a bit and snappiness is about reactivity after idle. IF it's set to 0 it will be fully reactive, but a higher value will make the phone lag a bit after IDLE. I didn't saw anything about consumption so I think we'll have to wait for a better android expert.

The other two, I didn't fully understood their meaning, but I found 2 web pages.

http://www.linuxinsight.com/proc_sys_vm_dirty_ratio.html

http://www.linuxinsight.com/proc_sys_vm_vfs_cache_pressure.html
[LG Optimus 2x] vadonka:
you can find a very good explanation in here: http://wiki.maemo.org/Swappolube
[LG Optimus 2x] Barnabe619:
What is the dir of the file in which we can apply these modifications in the kernel ?

https://github.com/SetiroN/lge-kernel-star

Sorry for my noobility :p
[LG Optimus 2x] rasmusx:
What are the recommended undervolting settings?
[LG Optimus 2x] miina_tokiha:
no need to uv.

battery life already good enough.

but you can try to uv 25mv at a time.

stability test, try more, then stability test again.

keep doing it until your phone feel slows down or restart.

keep the last stable value.

each phone is different.

for stability test, you can use Quadrant or Antutu.

just run the CPU test to safe time.
[LG Optimus 2x] fire3d:
i think the install script from all xx-20111210h1857 kernel versions is broken,

found this after checking the build.prop file, after flashing the kernel the build.prop

file is over 3mb in size, opening it gives a file with hundred's of every line:

# begin build properties

# begin build properties

# begin build properties

# begin build properties

# begin build properties

# begin build properties

# begin build properties

# begin build properties

and so on .....

[LG Optimus 2x] yukkio:
Full battery charge only gets 4129mv, with vorkkernel it gets 4172-4169mv. Does anyone has this problem?

Thanks.

BR.
[LG Optimus 2x] SetiroN:
"You found" by actual tests you performed or urban legends?

Those values increase the system's tendency to store memory into swap, which means compcache as we don't have any disk swap, which means real time compression. To be honest I don't think moving data from RAM to another place in RAM where it'll have to be compressed first is going to do anything but hurt performance by pointlessly using CPU time... but you're free do do as you wish:

those values can be changed at runtime anyway, no need to involve kernel modifications. Run them manually or add them into 90irontweaks (or whatever script you run late at init).

echo /proc/sys/vm/swappiness = 60

echo /proc/sys/vm/vfs_cache_pressure = 200

echo /proc/sys/vm/dirty_ratio = 50

I don't see anybody complaining about the normal release, so I suggest to use that one.

I know, late versions fix this by automatically restoring the backup.

Everytime you top up the battery, you're going to see a different value, no matter what kernel you use.

New build due in the morning.
