Paul who'd you be interested in helping nobodyAtall in breanging 3.0.8 kernel to Neo. He is looking for devs from other phones to help him port it to all 2011 xperia phones he got it working almost complitly on smultron (Xperia mini) more info here 3.0.x nAa kernel for SEMC 2011 line
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
finally kernel 3.0 .. i hope paul working on it for Neo and Neo V
[Sony Ericsson Xperia Neo, Pro] deccan451:
Somebody with kernel knowledge help nobodyatall ( wedgess, mechmetal, paul, Anyone), we want 3.0.8 for neo.. :)
[Sony Ericsson Xperia Neo, Pro] paul678:
Yes, I'll try to help also. I will fork the repository this week and start building on it :)
[MENTION=788040]nobodyAtall[/MENTION]
[Sony Ericsson Xperia Neo, Pro] paul678:
3.0.x is here to test.

Changes between nAa and this:

Exp#1
-Compiled with Linaro
-Updated Interactive governor and use touch-boost on it (maybe small things left to fix)
-Entropy tweaks
-Increase MAX and MIN readahead
-Update deadline to allow 0ms latency and increased read speed
-more to come

Download link

CM10

Warning Kernel boots very slowly and doesn't display boot logo so be patient.
[Sony Ericsson Xperia Neo, Pro] dugzino:
Yay! Finally a 3.0 with 'Interactive' governor!

Most important stuff to fix right now for the sake of testing the kernel, is the battery drain.

Oh and btw THERE ARE NO FREAKING KERNEL LOGO! = Phone charm decreased by 36,2%

EDIT

WiFi's not working.
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
yes confirm WiFi not working
[Sony Ericsson Xperia Neo, Pro] paul678:
Only -36,2% ? :laugh: I was thinking more like 43% or something :laugh:

Yes that's true, will fix this night if I have time. Also don't you guys have problem with Interactive? Sometimes it stays at min freq, will look into this in a few hours. And random reboots, random reboots on hard usage, I'll take a look at this also :)

Have a great day,Paul.
[Sony Ericsson Xperia Neo, Pro] dugzino:
Yes I had issues with that gov once I lock the phone and leave it for 10-20mins then use it again, suspect heavy lags for 5-10mins.

Couldn't test it more tho, sorry 'bout that.
[Sony Ericsson Xperia Neo, Pro] paul678:
1 May build:

3.0.8Exp#2

-Add overclocking (up to 1.4ghz)
-Add 460mhz freq (use it as min)
-Fix Interactive governor
-Maybe fix random reboots
-Various optimizations
-For wifi please test with a clean install (maybe it works)

Download:

3.0.8Exp#2 CM10-kernel

Report back, all the best Paul.
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
without clean install no WiFi .. i will try do clean install tonight
[Sony Ericsson Xperia Neo, Pro] paul678:
This wifi thing pisses me off. I haven't touched it at the beginning yet it didn't work...will figure it out until Friday.

The feedback I'm interested in is if reboots are solved/less frequent and if Interactive still forgets to work (remember use 460mhz min freq) and feel free to test 1.4ghz ;)
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Is this kernel 3.0.8 valid for cm 10.1?

Thank you very much in advance
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
i will try test it again tonight with clean install
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
for now no reboots problem and test notification light no reboot .. less frequent for CPU sometime stuck on 1017MHz and then back to 122mhz .. no problem with Interactive when i use 460mhz or 122mhz working good .. test 1.4ghz working good but not test it a lot of time

no WiFi with clean install .. rom working good and very smooth

i'm test this kernel with CM10 official nightly28/4/2013
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
tested with clean install

wifi not working even when min freq is at 460 mhz

kernel is smooth and fluid no lags

no random reboots till now
[Sony Ericsson Xperia Neo, Pro] tinyXperia:
If I replace the ramdisk myself, will this work on stock ICS?
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
yes it should

but don't mess up the sizes of different partitions
[Sony Ericsson Xperia Neo, Pro] georgeiulian89:
If yo make it,please share it,because i also want to use it on stock rom.
[Sony Ericsson Xperia Neo, Pro] tinyXperia:
Here you go, everything working fine so far (except for the general bugs).

One big problem: UI is very laggy, like 2 frames per animation, which is weird, since I tried nAa's kernel for Haida with very good grpahics performance.

edit: replace the space in filename with anything else, otherwise fastboot will give an error
[Sony Ericsson Xperia Neo, Pro] paul678:
The bug may appear on logcat/kmsg, my version has less ram reserved for surface flinger but I don't think that is the issue. I can't test on stock ICS as I don't have enough time but maybe if I see the error I can fix it for stock
[Sony Ericsson Xperia Neo, Pro] tinyXperia:
Gaming was smooth though, I'll try to get it logged.

Edit: here you are. Somehow upload of logcat.txt failed, so I had to zip it.
[Sony Ericsson Xperia Neo, Pro] satyr007:
for wifi - wrong ramdisk mby?
[Sony Ericsson Xperia Neo, Pro] dugzino:
Aw c'mon Paul!! No Wifi?! Seriously?! Dude, I'm about to insult you! :P

Your kernel goes faster in recovery mod than nAa's :/

It's really weird that Wifi doesn't work tho

Will logcats/kmsg help?

Interactive touch boost works btw.

EDIT

Still that bug when going off of lockscreen, lags like hell like as if the phone just booted.. (by putting min. freq to lowest)

Too bad for that lockscreen, scared I might miss an important call if it gets buggy..

Battery drains waaaay lesser than previous v3 kernel releases.

So, if I get it right, the fact it drains lots with nAa's it's because of the govs?
[Sony Ericsson Xperia Neo, Pro] georgeiulian89:
Thanks, but unfortunately it's messing up system/vendor/app in stock 587 :(
[Sony Ericsson Xperia Neo, Pro] tinyXperia:
I'm using haida partitions

Via Tapatalk on SEMC Hallon
[Sony Ericsson Xperia Neo, Pro] paul678:
I'm searching for that wifi thing, the strange fact is that I haven't messed with the drivers so they should work, I know cm10 doesn't find wlan0 interface. I'll take a look at stock wifiload script to see if it loads correctly because it seems it doesn't find/load/something...the wl12xx and wlcore.

About that lockscreen bug you say, hmm I don't have it anymore, I mean even if cpu gets stuck at low freq from time to time that's why I put the 460mhz there.

The 2 most important things for me to fix now are "WiFi" and random reboots (which are reduced but still happen)
[Sony Ericsson Xperia Neo, Pro] dugzino:
Yeah but, by setting lowest freq to 400Mhz it'll also increase battery drain.

BTW that lockscreen issue happens only with Interactive (100 to 1000Mhz) and only a few seconds (10 to 30).

I'm now using OnDemand and it runs good, still have to check battery consumption tho.

Anyway! I have no idea how to finish this p
[Sony Ericsson Xperia Neo, Pro] satyr007:
check this: https://github.com/paul678/msm7x30-3.0.x-nAa/commit/790e01b02d2c5d210ad2ce861959e1065f2f108d

-Wno-array-bounds \

-Wno-enum-compare \

try to delete these flags
[Sony Ericsson Xperia Neo, Pro] paul678:
I can guarantee you won't feel any battery loss at 460mhz, in the next build I'll test 900mv voltage on that freq and if it's ok (it should be) I'll push it.

And why is that, if I compile without them I'll have to fix some files that give warnings (which are ok since they come from mainline and not modified by us) in linaro :)
[Sony Ericsson Xperia Neo, Pro] paul678:
Here you go everyone. Test everything and report back. Have a great night, Paul.

Exp#3 CM10
[Sony Ericsson Xperia Neo, Pro] AF_624:
hi paul..

something is wrong...

i m using neo v whith pack rom 19.3.0 (4.1.2 cm10) and kernel doesn t boot... it even not pass to rom boot amiation. only black screen!

thanks for your hard work...!

rspect,

andre.
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
yes me too i can't enter recovery only black screen
[Sony Ericsson Xperia Neo, Pro] paul678:
Well that is a strange thing :confused: .img downloaded from mediafire or attachment on first post. Maybe upload went wrong, can you please check the md5sum of the .img file, it should be

1e9c2ca2f3b4ff32122f5ddffcfac72f

And anyone tried with stock CM10, I mean no pacMan or parandroid etc? I tested the kernel only on my rom which is based on CM10 nightly
[Sony Ericsson Xperia Neo, Pro] Tenacious:
MD5 matches and boots on fxp218. Guy's there is no boot logo so just wait until boot animation shows up.

[MENTION=4266283]paul678[/MENTION] for bootlogo to show on 3.0.x kernel it should be initlogo.rle
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
yes now rom boot CM10 nightly 5/5/2013

but i can't enter recovery to do clean install
[Sony Ericsson Xperia Neo, Pro] AF_624:
PacRom is based on cm10 nightly too.

I wait about 10minutes 2times.

The phone vibrate 2or 3 times, the led change from purple to blue 2or 3 times but phone don't pass from black screen.

Download from mediafire
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Installed 3.0.8 on hallon running cm10, wifi seems to work but random reboots. RamXpander cannot run because kernel does not support swap. Tried to OC 1651Mhz and reboot.

Cannot entry into CWM mode, led flash purple and after, blue but display doesn't show nothing, you must have to remove battery and boot normally but cannot wipe cache/dalvik because cannot go to CWM.
[Sony Ericsson Xperia Neo, Pro] dugzino:
No kernel boot logo! OH MY GOSH!

No CWM (and when access it you try, remove battery you have to)

8bit colors

Auto cache wipes on boot, normal?

CM10 FXP218 with only wiping cache/dalvik. Not a clean install.

PS: Sorry for sending logs.zip but, XDA don't want txt files anymore :/
[Sony Ericsson Xperia Neo, Pro] paul678:
The higher freq are there only for devices that can handle it, not all cpus are the same. For example mine can handle 1.6ghz for some time but it eats to much battery, however it's ok on benchmarks.

Edit: indeed 1.65ghz doesn't work as expected, I'll fix it :)

1. Let it like this for now, it's moving left to right anyways.

2. I'm sorry to all, will post an update with working recovery this night...I messed something

3. Could you please send me an image where you notice this, because I really don't have it

4. No, it does this on every boot? It's not normal and it shouldn't be related with my kernel.

Wish you all a great day, I'll come back later this night to post the update with working recovery.

Also some reboots are related to WiFi firmware, but I've seen on my device that it sometimes freezes when requesting early suspend and I'm on to resolving this first.
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
still sometimes WiFi drop
[Sony Ericsson Xperia Neo, Pro] dugzino:
Guess it's only me. Flashing latest nAa releases requires a fresh ROM install..

All I did was, wipe caches and flash your kernel.

Gradients go like this >> B&W bad gradient << (even worse actually)

I'm really the only one getting these so, I'll consider doing a fresh install on your next kernel release.

BTW, wanted to ask you something.

Can the build.prop create bad behaviours? Like lags and such?

PS: Even after 5 phone manual reboots, kernel logo still doesn't appear. #MakingStoopidJokes
[Sony Ericsson Xperia Neo, Pro] paul678:
Yes build.prop can create bad behaviour and the same can be said about init.d tweaks.

When I get back home I'll upload the revised #3build (at about the same hour as yesterday)
[Sony Ericsson Xperia Neo, Pro] paul678:
[B]Exp#3_1[/B]
-Rework and fix recovery
-Fix OC (small mistake by me)
-Small power management change (let's see if reboots are still as common when not using WiFi)
-Smaller kernel size
-Other minor changes.

Download

Exp#3_1 CM10
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Installed and confirmed, Recovery mode works to wipe cache and dalvik (tomoroow will try to do a backup) temperature seems like Lupus 32º-33º in standby (I live in a warm zone of Spain).

Still no bootlogo for kernel but, boot is very fast

Wifi works well and no drops so far, bluetooth works with my headset and to transfer files to pc.

It seems very very stable, 1651Mhz freq works :good:

Still a problem, for me is an important problem, Kernel is not compatible with SWAP, because that I cannot use ramXpander that works very fine on my hallon, would be possible to have it?

Thank you very much paul to give us the most stable version so far (at least for me) of this awesome kernel, only SWAP needed and it will be perfect!!!:D:D
[Sony Ericsson Xperia Neo, Pro] dugzino:
I guess it was an issue with latest changes! My screen is back to normal without wiping..

Boot is indeed faster like yuxandyou

Will report more later :)

Thanks again Paul!

BTW, kernel logo is sti... Ok, I'm out >>>

EDIT

[MENTION=4266283]paul678[/MENTION]

I just tested nAa's 3.4 kernel release and I get that colors issue again. If you could check his repo and push your latest fixes you did on the 3.0

Because on your latest release you did fix them.

-Fix OC (small mistake by me)
-Small power management change (let's see if reboots are still as common when not using WiFi)

Guess it has to do something about one of these 2 fixes.

Getting those colors issue since that "LCD undervolt" push on his repo by Mike.
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Installed a couple of days ago, it works awesome, no reboots, wifi works, BT works for headset and file transfer. At this moment, it's the more 3.0.8 stable kernel that I ever tried, and works fine with swap, now my device has a new life.

Thank you Paul for your hard work
[Sony Ericsson Xperia Neo, Pro] deccan451:
with latest 3.1 kernel jb 4.1.2 everything works super smooth & stable .... please make this kernel available for stock ics it supports 3.0.8 i tried with nAa kernel boots but continuously Flickr :fingers-crossed:
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
what about WiFi still drop??
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
No drops for me since yesterday, with lupus, when you pair a BT headset, wifi drops for 15 seconds (more or less) but with Paul's wifi doesn't drop never (at least for me)
[Sony Ericsson Xperia Neo, Pro] paul678:
Great to hear this! What about deep sleep because I still have reboots when phone goes or comes out of deep sleep (2 per day). I'm testing this night some changes maybe I can get rid of them.

Next release will come for CM10 and CM10.1 and I'll see about stock (I need testers for it, let me know who's in)

Also later this week I'll test the 3.4 to see how it goes.

Cheers, Paul.
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
The kernel is plenty functional but I have an issue, I have a SIP account and I use Bria Pro app, with kernel 2.6... app runs without any problem to make and receive calls, on wifi and 3G. But when I change kernel to 3.x.x (I tried yours and nAa's 3.4.0) the account behaviour is not correct, lot of lag in calls and no possible to establish a fluent communication. Is for that that I back to Lupus, but this night, I will flash your kernel again and make a logcat (this night because I need SIP account to work).

I know that isn't a wifi drop problem because I hear music in streaming and no problems nor cuts in songs, and I view films through wifi from my computer with ES file explorer and no problems to play it on wifi

If you need something to help to identify the problem, please tell me and this night I will do.

Thank you very much in advance
[Sony Ericsson Xperia Neo, Pro] deccan451:
For stock ics kernel testing I'm in ..
[Sony Ericsson Xperia Neo, Pro] bitoyz13:
I'm in for stock ics testing too.. My device is neo V..pls pM me dev

For me Linus Torvalds is the greatest man on earth
[Sony Ericsson Xperia Neo, Pro] yuxandyou:
Sorry for the delay. I attach to this post the logcat, as I explained I'm facing a problem with 3.x.x kernel that doesn't happen with Lupus (or any other 2.6...). All works perfect, but I have a SIP account configured in Bria 2.0 Pro app, when I try to make a phone call, communication is choppy and after hang up, wifi dissapears and take 15-20 second to come back and work again.

I don't know what to think because the rest of the functions works perfectly, but I need SIP account.

I post the logcat in the moment that I opened the app and tried to make a call to two different numbers. I don't know if it helps, but there is.

Thank you very much in advance
[Sony Ericsson Xperia Neo, Pro] BuzzyMind:
Okay. So I tried this kernel of cm10 fxp219 everything working good so far. The battery is draining a bit faster than with fusion 5.4 I'd say 1.5 times. The only problem I have is like with all naa's kernels google play is slow and gives me connection timed out error and 927 error. This happens only with google play idk why, my connection is good tested it with speedtest.net app
[Sony Ericsson Xperia Neo, Pro] dugzino:
Can you give me ur baseband version.

Settings > About Phone > Baseband version.
[Sony Ericsson Xperia Neo, Pro] BuzzyMind:
77 btw why do you need that? :P
[Sony Ericsson Xperia Neo, Pro] dugzino:
Because it's really weird for a very few to have this issue when lots aren't having.
[Sony Ericsson Xperia Neo, Pro] paul678:
Random reboots are mostly solved now (have some left when using wifi), still in testing.

Also battery life is a bit improved. I'll let you know when kernel is ready to release :)
[Sony Ericsson Xperia Neo, Pro] paul678:
No reboots for 25h however wifi may cause some, if it does let me know because I haven't downgraded yet like nAa did.

Link:

Exp3_2 CM10

If all goes well by monday you'll have a stable version for both JB versions.
[Sony Ericsson Xperia Neo, Pro] Tenacious:
Running it for almost 2 days now and didn't experienced any reboots over 3g or wifi only bugs I found so far is interactive governors sometimes after screen unlock gets stuck at min frequency and had only 2 wifi drops during these two days.

And phone doesn't heat as on nAa kernel which results in better battery life.

Thank you paul678 for making 3.0 kernel stable while 3.4 is still in development.

Any chance for zram version?
[Sony Ericsson Xperia Neo, Pro] Tenacious:
I had my first reboot with this kernel, phone was charging overnight and in the morning I was greeted with pin request, looks like it's known bug where phone reboots when reaches 100% battery. I extracted last_kmsg http://db.tt/6pRzeywI
[Sony Ericsson Xperia Neo, Pro] ChristO1624:
will u try to do your 3.4 kernel? ;) 3.0.8 development is gone I think..
[Sony Ericsson Xperia Neo, Pro] deccan451:
nAa focusing on 3.4+ kernel , paul is trying to make 3.0.8 kernel more stable for daily use he almost succeeded, [MENTION=4266283]paul678[/MENTION] make 3.0.8 more stable before shifting to 3.4 kernel
[Sony Ericsson Xperia Neo, Pro] paul678:
Have to take a look on this, but it will take some time because I'm a bit busy with university too.

I'll also try to use no_console_suspend to debug the kernel because the log is silenced when entering deep sleep and I had some reboots just after restarting the phone and letting it go to deep sleep. Thanks for the log :good:

From my experience 3.4 is buggy with CM10 (lower performance and buggy animations) so I'll support 3.0.x as long as I can. For now I moved my device to CM10.1 to experiment with 3.4 kernel. I'll let you know when there's anything new to release.

If you want you can also check my github to see any commits I might make.

Have a great night,

Paul.
[Sony Ericsson Xperia Neo, Pro] themike10452:
hey there, any chance of getting an arc/s version? nAa stopped the dev of 3.0 kernel for our hdpi devices
[Sony Ericsson Xperia Neo, Pro] pathik_ maruf:
Eagerly waiting for an update and stable release...

Sent from my Xperia Neo V
[Sony Ericsson Xperia Neo, Pro] paul678:
Hello and good morning XDA,

I'd like to know who can test a 3.4 beta kernel for CM10.1(only) and give some feedback for the following:

general stability

general performance

2D/3D performance compared to "stock" 3.4.45 nAa

Camera issue on Xperia Neo (remember wipe camera data after flashing kernel)

Please report back as soon as you can, happy testing everyone :D

Here is the kernel
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
i'm pm me the test kernel

i will report the performance as compared to 3.4.47 kernel mike's build
[Sony Ericsson Xperia Neo, Pro] bluestricker_21:
Kernel is already given just have it a try and then report
[Sony Ericsson Xperia Neo, Pro] mido_fedo:
thanks my bro and i know you say "kernel for CM10.1" i try it with AOSP 4.2.2 boot but i can't get WiFi work :(
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
Very slow boot

Camera preview not working sometimes camera freezes

Wifi modules not being created

Subway surfer working was facing fc on 3.4.47

Didn't feel any Difference in gaming performance couldn't do a benchmark as Wifi was not working although I don't believe in benchmarks

I'm using haida
[Sony Ericsson Xperia Neo, Pro] paul678:
Oh sorry for wifi, I forgot to change the wifiload script,

modify it using any file explorer to loog like this (you'll find it in system/bin)

/system/bin/insmod/modules/wl12xx.ko
/system/bin/insmod/modules/wl12xx_sdio.ko

For camera have you cleared camera data after flashing the kernel? And also I recommend a dalvik wipe :)
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
Did a clean install

The is no Wifi modules in lib/modules folder

I didn't understand your last post

Did you meant that we should copy modules from mentioned folder to lib/modules
[Sony Ericsson Xperia Neo, Pro] paul678:
Modules are not in /system/lib/modules

they are loaded from /modules. This is the way in my ramdisk

And I forgot to change the wifiload script from the ramdisk. The proper release will have it done correctly so you won't have to modify the script by hand.

Just change the last lines from wifiload script located in /system/bin and wifi will work ;)
[Sony Ericsson Xperia Neo, Pro] voyteckst:
Will the release work also on CM10?
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
No he clearly mentioned in his post cm10.1 only
[Sony Ericsson Xperia Neo, Pro] voyteckst:
No. He wrote "I'd like to know who can test a 3.4 beta kernel for CM10.1(only) and give some feedback". So it doesn't clearly mean that it will not work on CM10 ;)
[Sony Ericsson Xperia Neo, Pro] avinashrocks1990:
Then try it out
[Sony Ericsson Xperia Neo, Pro] Tenacious:
Hi Paul

Performance seem same as mike's 3.4.47 kernel about stability so far looks good but it's too early to say for sure because in past I was able to run 3.4 kernel for about 2 days without issue and then reboots who'd start out of bloom, camera doesn't work at all on Neo at any resolution it just freezes and after some time it just fc (wiped camera data and did cache wipe). I'm on mike's cm10.1 0605 build.
[Sony Ericsson Xperia Neo, Pro] paul678:
Well then it means back to 377/375 mb of ram for Neo. I'll try out a few adjustments here and there, a new ramdisk and hopefully smaller one and release when I have time, no promises because I have a pretty hard exam on Wednesday :fingers-crossed:
[Sony Ericsson Xperia Neo, Pro] dontbelive:
i love your modified 3.0.8 kernel :D more ram , faster and more stable :) great work thanks , is it possible to get 386 mb ram like the 2.6XX version one ?
[Sony Ericsson Xperia Neo, Pro] paul678:
Well I don't think so, problems with stability and because of them now the 3.4kernel is stable for NeoV (Neo will give camera errors) with 374.

After I finish with all my exams (4 July ) I'll do some extensive research and work on this kernel (3.0.x and 3.4.x) until then I don't have time.

Wish me luck guys, cheers! Paul :highfive:
[Sony Ericsson Xperia Neo, Pro] deccan451:
first all best for your exams ... second waiting for next update specially for neo kernel with all fixes :highfive:
