Hi ,

I'm giving the test report :

* connectivity : - wifi , bluetooth , gps , radio : good

- data connection : I had problem with it but I don't really know if it's kernel or operator related :/

* hardware : camera ( front and rear ) , screen , physical keyboard , speakers , eare phone , light sensor , accelerometer , proximity sensor , notification led , led flash : good :good: and 100% battery bug is gone :good:

* stability : I got a freeze successed by a reboot once ( when on web browser ) : last_kmsg attached

- browser was going crasy and is not loading webpages before the freeze accident

* kamenu : enable to change min - max frequencies but able to change governors ( the kamenu script was not well tested )

* init.d : not well working , it is not setting frquencies like in the script , so not working :/ but I fix it with the script attached (zip_init.d.zip : thanks to the dev , the thread is here : http://xdaforums.com/showthread.php?t=1933849 )

* battery life : I used phone heavely with wifi and data connection ON so battery seemed pretty solid however when idle , the phone seem to have a wakelock (?) which was not well detected with wakelock detector there was a battery drain ( I can't really confirm because I flashed the kernel on top of mesa 3.0 so stuff need to be recheked ) :/

* performance : speed is AWESOME boot time is repectable ( 48 seconds ) , game loading is really fast in addition to butterly smooth scrolling and a smooth music play back ( no cuts :D ) :good: !!

I hope this will help and I'm ready to test and report new builds as much as I can :D

reboot bug ..

Hi ,

after more than a day and half of usage of the kappa kernel , I faced multiple freezes and random reboots some of them happen on the web browser or when launching the game " don't touch the white tile " ( or " piano tiles " ) half of times the phone frezes and reboots , which make this bug very annoying and a serious one , here I brought some last_kmsg logs in the attachment ..

EDIT : another bug need to be mentioned , is that video streaming on facebook mobile page ( where I noticed the bug ) is half of the time laggy or with very low fps lets say ..

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Hi there,

first of all, thanks for your help!

I'm trying to find out what is actually happening with the lag. Personally not a gamer (Except for 2048 ;) ) nor I watch videos on my phone.

For basic stuff like I do, I never saw any "appreciable" lag. Yet... Very recently somebody very close to me installed Kappa 1.7 too and I'm getting reports of lags and stuff. He's more of a "phone user" than me ( ;) ) and he also reported lags happening from time to time when either browsing or watching a vid.

I managed to reproduce something similar to that (except for the reboots) the other day by running Antutu Benchmark multiple times in a row. After the second or third time, the OpenGL test would simply freeze. Not the whole system, just Antutu.

Gathered all the patching strength I could, called my trusty bug seeker dog. Checked logs... Nothing that could really tell me anything wrong. Then decided to try something stupid... Play with entropy generation.

As everything relies on ramdom data, when "not enough" random data is available, the system may just freeze that application till available again.

Although Kappa had already Havege builtin, tried first to replace it with Frandom... And suddenly no freeze anymore.

Yet, was quite surprised when flashing back the phone with Kappa on Havege... Lags were gone too.

Long story short... I'm battling with this issue a bit.

I rebuilt another branch ( this must be the 20th after 1.6) that starts cleanly from the master branch. Added the most relevant patches to avoid chaos and make it more easy to follow. I'll keep testing this last version before distributing it (Kappa1.7Master).

Here is 1.6 (all 4 devices) with the battery bug fix while I debug 1.7

I had flash Kappa Kernel 1.6 with battery bug fix for my coconut, but until now my coconut still not boot up. Of course I had trying another method by re-downloading the kernel, using flashtool, then fastboot command by erasing userdata & system, but, still the same, my coconut won't boot up. Is anyone (a coconut users) success to boot up with this kernel?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] job.bousix:
Hi kast ,

please , when testing the next kappa build , install this game ( piano tiles ) , because it is a way to reproduce the freeze and reboot issue even on the latest fixed kappa v1.6 I got a freeze and reboot when launching this game ,

thank you very much :D

Hi there,

for people willing to test ongoing 1.7 Betas... I tried to make it a little easier.

My friend Jenkins is making every night a new build based on the latest committed changes. You can grab the releases here:

Kappa 1.7 Beta Releases

And Travis-CI will tell you if at least it builds

This was also posted in the opening thread.

Thanks,

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Did you have the freeze and reboot before the battery bug fix?

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] job.bousix:
Hi ,

I don't know if its related because I have just started playing this game , which means only tested on the new kappa 1.6 v2 with the bug fix but I retest it with the old one and I will test also the new build of kappa 1.7 kernel and report a full test report as soon as possible :D

EDIT : so I flashed back the old 1.6 version , booted the phone , then tested the app at launchin more than 6 times but there was no freese bug I rebboted the phone and the same result , but I was not weel confident of the results so retested the new version of the 1.6 and surprisenly I have no freeze bug also , which means that this bug is not battery patch related :good:

now I will test the new 1.7 build and report back the full test report tomorrow morning , I guess , or maybe later in the day ..

thanks agan for your work we really appreciate it :D

Hi kast ,

there is a wifi problem : it is not switching on as expected like previous builds ( mango with the latest jenkins builds ) and and when flashing lupus wifi switch on and works fine , I don't know why ?

I will attach a dmesg as soon as possible or you can test it yourself and fix af it's possible because I can't continue testing if wifi don't work :/

thank you very much for your precious work :D

EDIT : there is no wifi modules in the rek folder of the ramdisck

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Check again the latest releases on Jenkins... Wifi should work now.

Me silly, didn't update the default configs... The automatic build process was using old ones with no embedded wifi drivers.

Sorry about that,

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Bitterballen:
Yeah, now my phone has successfully booted up :cowboy: I will reporting back after I test this kernel for another minutes.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] job.bousix:
Hi !

now I will give you the test report of the latest kamango13 build

* connectivity : - wifi , bluetooth , gps , radio , data connection , tethering : good

* hardware : camera ( front and rear ) , screen , physical keyboard , speakers , eare phone , light sensor , accelerometer , proximity sensor , notification led , led flash : good :good: and 100% battery bug is gone also :good:

* stability : everything seem to be very stable exept one time when apps like root explorer and titanium backup didn't want to run which was fixed by a reboot :D

* kamenu : agan not able to change min - max frequencies but able to change governors ( the kamenu script was not well tested )

* init.d : still not well working , it is not setting frquencies like in the script , so not working :/ but I fix it with the script attached (zip_init.d.zip : thanks to the dev , the thread is here : http://xdaforums.com/showthread.php?t=1933849 )

* battery life : I used the phone very heavely to make a faster test , and the battery life on screen is abselutly IMPRESSIVE !! here is my counts :

on screen with wifi OFF : 13~18% per hour

on browser with wifi ON and data OFF : 15~19% per hour and streaming 18~21% per hour , and with data everyone knows that is battery draining :p

when gaming : ( piano tiles ) 15~20% per hour

* performance : speed is AWESOME boot time is good ( 41~45 seconds faster than the other build 21 seconds from them are taken for the kernel to boot :good: ) , game loading is really fast in addition to butterly smooth scrolling , smooth gameplay and a smooth music play back ( no cuts :D ) excelent :good: !!

I hope this will help and as I said I'm ready to test and report new builds as much as I can :D

and I hope also v1.7 will be released soon because in two weeks I will travel for university and will not be able to access any computer and do stuff like this like I used to do till now :(

PS : if I face new bugs I will list them here :D

EDIT : I faced the "kernel reboot bug " , when I boot the phone , then there is the vebration then kernel logo then it just freeze there after several seconds kernel reboots agan "seccesfully" to system , I have attached a last_kmsg which I don't know really if it's related to the time of the bug or not ..

thank you very much :D

How can Doppler Modules work on kappa :eek: ?

They aren't even remotely compatible. :eek:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Quite strange you got it working by flashing another kernel's modules. Drivers / Modules are tied to the kernel by what is called "Version Magic"... Generally you can't load a driver which was compiled against another kernel, with a different version magic.

Anyway... Better download the latest Kappa 1.7 from here: http://build.ka.st:8080/job/Kappa/ws/release/

Take care,

Ka.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Thank you very much for this pretty impressive test report.

I look into the kernel log you provided me with, it seems that the kernel stop just after setting up the serial console. Then reboots.

Could find no error message, just reboot. Checking if any patch was made to msm_serial on some other kernel...

From today the kernel is compiled with Linaro 4.9, toolchains provided by Christopher83 of this very same forum.

The toolchain I'm using was compiled with optmisations for the cpu our devices have. Kernel is slimmer and hopefully faster.

Jenkins is aware of this change and new builds will be made with he new toolchain.

Now need to check what happens with init.d

Cheers!

Need to test battery life now, i will update this soon :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] job.bousix:
Hi !

well that's our duty as users of free development ;)

I faced the freeze and reboot bug twice on the latest build when launching perfect piano from numerous times of usage of that app , the freeze has taken too long so I was forced to pull the battery out which means no last_kmsg , that happened yesterday , and today agan the phone froze at the launch of the same app but hasn't taken so long and rebooted and hopfully I got the kernel log of the error wich is attached here :D

Also it's not like before , the freeze bug now is not successing a lag , I mean everything works great and then when launching the app it just freeze there and reboot ..

EDIT : I have flashed the kamango16 build of today , and I will just report if there is new bugs or if old bugs are fixed ..

EDIT : First impressions :

*the new build feels less stable and a little bit laggier than the kamango13 , I say that because of the lag in the video streaming is back but not very important as before , not as smooth scrolling as the kamanago13 kernel was after restoring a clean backup , phone usage feels better smilare to kamango13 .. , and I faced the freeze and reboot bug with the perfect piano app , agan , for the 4th or 5th launching after flashing the kernel ..

*no reboot bug at kernel boot till now ..

*also just saying that the init.d support still missing and the kamenu bug is still present in case you made a modification to fix those two bugs ..

thank you very much :D

Hi kast ,

kamango18's performance is great :good: but unfortunatly the "kernel reboot bug" at boot is still present , you will find logs in the attachments :)

also the freeze and reboot while launching a specific app (perfect piano) still present , but unfortunatly I was not able to drag a last_kmsg , and this bug is hard to reproduce , once it happen agan I will try to bring you the log :)

whenever I restore the clean backup I made , apps are not able to load up just stuck at start screen of the app , but it can be fixed by a reboot ;)

sorry for the missing logs I will try to provide them soon when I can :)

Hi!

Thanks for your reports.

I finally managed to grab another Mini Pro after my brother stole mine (his was broken, got a Mini too anyway). Last week ordered the first 3 Mini Pro I could find on Ebay. The first arrived yesterday. Can test again on Mini Pro too (although this bug should appear on all devices).

With 3 I should have enough even if my brother decides to steal another one ;)

Now... There is a version pending testing which hopefully is going to be more stable. The changelog is (most relevant fixes):

d0a5467 CPUFREQ : Governors : Removed some governors

a9000e9 Added SmartMax Governor

c9a8b04 binfmt_elf.c: use get_random_int() to fix entropy depleting. Original commit: https://patchwork.kernel.org/patch/1745611/

829c3b4 block/bfq-iosched.c: BFQ scheduler tweaks (thanks pkgnex & Khrushy from Franco dev team)

fd44c8b ashmem: avoid deadlock between read and mmap calls

52ce75c Ramdisk: Fixed init.d execution and KaDNS script

a4667b8 ARM: 7592/1: nommu: prevent generation of kernel unaligned memory accesses

74ad276 ARM: crypto: add NEON accelerated XOR implementation

d7ce966 drivers/staging/android: backport timed_gpio form hammerhead

8aa059d ARM: 6998/2: kernel: use proper memory barriers for bitops

76125e7 random: entropy tweaks are all the rage nowadays

9ea022e mmc/core: increase limit_us

abcee44 Deadline tuning thanks to DerTeufel

461aa52 cpufreq: stats: Don't stop notification call chain

6a592c6 cpufreq: Memory leak with sysfs when stats table are freed

c71476b wireless: Fix memory leak

b9a181c mmc: disable crc for better performance

aa28a95 deadline: Allow 0ms deadline latency, increase the read speed

I've put in bold one commit, related to a CPU Governor I added... Looks interesting to me.

I was looking around to see if there was anything else to make this kernel battery friendly (I'm sure there is plenty more) and saw these articles/posts here:

http://xdaforums.com/showthread.php?t=2156311

https://plus.google.com/+ChetKener/posts/CTW2dnmtJeT

Adapted Maxwen's code a bit to suit our devices but still pretty long way before I nail the correct parameters for ramping up, down and the lot.

It runs... But maybe worth testing all of this a little before releasing it. Or do you want me to push it the way it is and we'll test it directly all together?

Tell me if you prefer to receive Betas as they come...

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] job.bousix:
Hi !

In my opinion , pushing it will be better , more of us will be able eo install it and the test will be more effective , and details verification will be faster :) ( waiting eagerly to test this one :D)

And thanks a ton for the work you do , the kappa kernel now is ensuring more and more performance and also kepping all the features we bought our 3 years old phones for :good:

Hi ,

I faced agan the freeze and reboot bug when launching perfect piano app , finally ! and hopfully I got the last_kmsg attached here :D

I need to mention also that :

-this kernel feels less smooth than the last build , maybe because of enabling uksm (the script kaUKS is uksm enabler right ) ? ..

-no kernel reboot bug till now .. :good:

-just a very little bit of lag in facebook video streaming on the web browser ..

-init.d is now fixed :good:

-kamenu still fails to change cpu frequencies :/

-MASSIVE MUTITASKING !! with wifi off so wifi apps don't load all , I'm able to switch between 12 heavy (youtube..) , medium (gallery..) and lite (calendar..) apps without them being killed !!! :good: ( is it thanks to uksm ?)

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] kast:
Hi there,

I'm looking to the lack of smoothness compared to last build. Checking into UKSM... Odd though.

For the reboot... I guess this is my new "battery bug" ;)

I'm treating my poor Mini the worst way I can. Start several apps, jump from one to the other. Launch Antutu several times, run that game, exit, relaunch it, exit... Several, several times. All of this with the phone connected to my computer to catch every single drop of interesting log may help in case the phone reboots. Yet... Nothing, the phone is stable like a rock (ok, a little rock).

Is this the cade of "while you watch it'll never move"?

The last_kmsg you posted... Thanks a lot. Don't get me wrong, I really appreciate your help... But... There is absolutely no sign of a Kernel Panic, in other terms, that the Kernel crashes and forces a reboot. Yet, you tell that your phone reboots. The last few messages in your last_kmsg show a normal phone running... At least to my eyes.

Probably a logcat would contain the reason for the reboot... But for that, you'd need to have your phone connected to your computer like I'm doing right now. And in case it just doesn't want to happen when the phone is connected? Anyway, might try with an app I found in the store that continuously saves logcat data to SD for later inspection, even after reboot.

Cheers,
