Hi, in with alogcat I see a lot of messages of this kind:

07-23 07:45:48.370 E/CM PowerHAL( 503): Error opening /sys/devices/system/cpu/cpufreq/ondemand/up_threshold: No such file or directory

07-23 07:45:48.370 E/CM PowerHAL( 503): Error opening /sys/devices/system/cpu/cpufreq/ondemand/io_is_busy: No such file or directory

Using k^kernel 2.6 uv (ondemandx) with ADC ROM R10. The messages come in boosts (say about 40 lines) every couple of seconds. Didn't adjust freq ranges with nstools. Any idea where these come from, if they indicate a real issue and how to fix it? Anything I can do to investigate?

Hello Christopher,

I don't know why, but I m not able to load the first page of this thread. Maybe to much elements? Im on cm11r10 by ADC using your kernel.

written in stone
[Galaxy S Plus I9001 Android Development] Hugo-PT:
Maybe it's your connection or browser. I do not have any difficulty opening that page.
[Galaxy S Plus I9001 Android Development] smitharro:
Though the page is loading fine (in my XDA Premium app) I can confirm that scrolling this (huge) page (with a lot of information) is really sluggish on my i9001. On my laptop with Ubuntu and Firefox however nothing is wrong. So maybe it's a little bit much for this phone...
[Galaxy S Plus I9001 Android Development] emyoo:
I do not think is related with the phone... I think it s a bug of the app in relation with the OP page content...
[Galaxy S Plus I9001 Android Development] Droehnemeier:
Yep, it is app-related. I just opened a hotspot, now I m using my Tab3. The problem is the same! So its nothing wrong with the device. Can someone recommend another xda app? I just own androids. I want to read the op, because it's important to read the description of thing I use. And no dev likes questions without reading op.

By the way a ton of thx for your awesome work christopher!!

KKernel 416mb

Is anyone more having freezes with KKernel 416mb UV?

Would a less memory version be more estable?
[Galaxy S Plus I9001 Android Development] JohnKersten:
Yes. I had the same issue and flashed the kernel with the min. amount of free RAM its more stable now.
[Galaxy S Plus I9001 Android Development] tonibm19:
KKernel 406mb

Now Its the same or worse with 406mb version.

Freezes happen playing Clash of Clans or Minecraft.

Could it be related to 16501 MHz overclocking? My CPU scheduler is smartassv2

Stock kernel better for games

Flash stock it will ensure you more fps and less stuck in games. Heard that it has to do with surfaceflinger having less memory alocated than stock. But I don't know for sure this is the reason/answer.

398 Ram

398Mb Ram version also freezes when i play Clash of Clan or even sometimes on Whatsapp,FB etc.And another observation that this Freeze happens only when your data plan is ON
[Galaxy S Plus I9001 Android Development] Rhonin86:
Have you guys checked if it only happens with K^Kernel ? Does this kind of problems also appear by using the stock kernel ?

Have you deactivated dataconnection and tried it all again - just to figure out if it is related to the data-connection ?

It would be nice to see a little schedule like

Stock - data on - np

Stock - data off - np

K^Kernel - data on - freezes

K^Kernel - data off - no freezes

just an example !!!

Just to figure if it is related to the kernel itself or the kernel in coneenction with data transfers.... Maybe we find a pattern that helps the devs

Read you again

Rhonin
[Galaxy S Plus I9001 Android Development] tonibm19:
Tried stock kernel

Mobile data connection ON - Freezes, just like with KKernel

Mobile data connection OFF - No freezes at this moment.
[Galaxy S Plus I9001 Android Development] DreamerTKM:
I'm using the 416MB OC ExUV version with data always on. But I didn't experienced any freeze other than the lag when Facebook + Messenger + Google Keyboard open together. Last time the lag is very huge and sometimes cause some freeze for awhile but after that I found that the issue caused by AVG. Once removed it, everything is fine.

Hi does our kernel support this

...?
[Galaxy S Plus I9001 Android Development] XeLLaR*:
If you want immense battery drain, the hardware supports it, yes. The touchscreen will be awake 24/7 though (unlike the LG KnockOn supported devices which have special hardware for that) thus draining an awful lot of battery while doing nothing. Also it will trigger in your pocket alot..screen turning on and this will drain even more juice out of your battery.

i make clean install of rom

gaps and set up phone

all work perfect

install kkernel

after viber installation phone freezes and cant type pin or cant log on when i pull out my sim

so far my knowlege problem is between viber and kkernel at boot

tried all versions

only stock kernel works

and if i flash kkernel once and flash to stock back freezes is still here

Also mx player won't play video files with mp3 audio format. it will just crash. so my guess is that maybe new mp3 hardware feature decoder is the problem. with 2.7 ver no problem at all, all videos play ok and viber work too.

Sometimes turning wifi ON does not see the available networks Yours!? Besides that big improvement on 3D games side ;) 10x!
[Galaxy S Plus I9001 Android Development] crishurazvi:
Data problems.

I've recently switched carriers and this problem occurs to me. I've always used my phone on 2G networks to preserve the battery and to reduce my internet consumption. My current internet provider is now forcing me to use 3G instead of 2G, and my phone is going crazy.

So after a week of investigating I've come to this results:

I've tested out on several roms, and the result are almost the same:

- With stock kernel, I can connect to data and use my phone for a few moments, and then it randomly shuts down.

- With custom kernel, especially K^kernel (for 4.4.4 and 4.2.2), I can connect to data and then immediately shuts down.

I can connect to wi-fi without any problem, and the phone is working great. Sometimes I hear a strange noise when it shuts down. I've tried changing the APN, network type, everything in the data settings and still nothing.

Searched the internet and couldn't find any clue on what is going on. I believe it's not the carrier to blame, but the phone. I'm open to any suggestions.
[Galaxy S Plus I9001 Android Development] MajorD.:
Hey Christopher,

could you add the possibility to OC the GPU ?

Look at this commit on GitHub:

Gaming peformance?

Has graphics performance improved? Are you using 416mb version? For me stock has better gaming performance than K^kernel 2.7 but I would switch to K^kernel again if gaming performance was better.
[Galaxy S Plus I9001 Android Development] calculate:
I've got same problem, but then I found in extended wifi-settings a menu

item called country code. I chosed Germany and I everything is ok.

You must go to wifi and then press the "three points" button below.

silent ringtones

Finally I found out that k~kernel 2.8 (I'm using the 416MB UV version) - on cm11 r12 with Viber (at least 3 latest updates) installed turn off the touch screen

You can go back to k~kernel 2.7 (getting back to orginal kernel makes no changes but

With 2.7 it's no more possible to set mp3 as a ringtone. It is silent.

The answer is unistalling Viber until the problem would be solved or wait for k~kernel 2.9 or doesn't use mp3 as ringtones.
[Galaxy S Plus I9001 Android Development] tonibm19:
v2.8

I tested the v2.8 because Cm11 r12 performance was bad (memory leak?). I tested the 416mb uv version.

Performance has improved, especially overclocking at 1,6 ghz. And wifi range seems bigger.

But the kernel is unstable, it often reboots (in Clash of Clans) or shutdowns (in Chrome), and during some seconds it has huge lags. It rebooted in Clash of Clans and The first 2 things didn't happen with stock kernel.

Any posible solution?

the right version of R13 (20141011 Release 13) has kernel v3.4.104, this KKernel V2.8 has v3.4.103 ;)
[Galaxy S Plus I9001 Android Development] smitharro:
You're right, you have the updated version. Xellar accidentally uploaded an older version of R13. At the time I used that buggy outdated version, thinking it was the latest one... Installed this kernel anyway, because of it's overclock possibility. So far no problems!
[Galaxy S Plus I9001 Android Development] herath:
Phone freezes

I was experiencing phone freezes(apparently due to viber) with the Release 12 stock kernel and K^Kernel V 2.8. I am no longer having freezes with the release 13. But when I tried to use this kernel V2.8 with release 13, the phone started to freeze again. Cant do anything when it freezes right after it finish booting.
[Galaxy S Plus I9001 Android Development] signs23:
Which kernel version do you use? Maybe you had 720p video enabled?

Did you do overclock with EXUV Version?

You could just go into recovery and flash another kernel.

Im using R13 with 2.8 398MB, and no problems so far.
[Galaxy S Plus I9001 Android Development] herath:
Tried both EXUV and UV(398MB version) with no overclock. The freez is caused by the mp3hardware decoder commit as i understand(Commit ). I replaced the the with https://github.com/Angels-group/pro...sm7x30-common/proprietary/lib/libOmxMp3Dec.so.

However, it does not look like hardware mp3 decoder thing is working with the orginal library. I can see " D/AudioPlayer( 169): start of Playback, useOffload 0" in the log.

Thanks.

First shutdown after first release

Kmsg is empty
[Galaxy S Plus I9001 Android Development] Christopher83:
Hi thanks for your logs,

but, unfortunately, they can't be so useful, after a shutdown/reboot/freeze I need the /proc/last_kmsg

Instead /proc/kmsg is not properly a file, it's a ring buffer, you can read it by running dmesg command or by running cat /proc/kmsg when you want to see the printed log messages on a running system.

Merry Christmas to everyone!!!

Yup! I know! It is weird..this is also happening for the first time with me.. it may not be a huge difference..370 & 378..but it does make a slight difference, right? Try leaving your wifi ON & connected to a network for a couple of hours, and double check? ;)

[Galaxy S Plus I9001 Android Development] m0e_03:
Am still try to figure out what went wrong with my wifi functionality while having ExUV 378mb on board..

To all, please remember that even though our model (i9001) is similar, the hardware components still varies from one another. ExUV kernels working on some devices doesnt mean that it will surely work very well on your device too. So if problems occur, then you should try the alternate UV kernel (not the ExUV kernel). ;)

Hi I have a strange problem with the kernel or the rom (kk adc) when I swipe out the notification bar some lines appears... Maybe they're glitches
[Galaxy S Plus I9001 Android Development] emyoo:
First WiFi problems. After updating Gapps with the newest ktulu package wifi stopped working, with standard Kernel WiFi is OK when flashing 370 version of K'Kernel does not want to turn ON anymore... anyone else?

Till now I have used only exUV versions will try for the first time the UV one... keep in touch.
[Galaxy S Plus I9001 Android Development] Marshian:
I don't have those problems. Same set-up though, beta 1 ROM with ktulu's gapps and K^Kernel 1.0 ExUV 370MB. (Haven't updated my signature yet.)

After flashing ktulu's gapps for the first time I did have some issues, more specifically swiping didn't work for me. I solved it by doing these steps:

Wipe system & cache

Flash ROM

Flash (ktulu's) gapps

Flash K^Kernel

Fix permissions

Now everything appears to be working perfectly. Perhaps you could try this as well and see if this solves your problem? (You don't lose any data doing this.)
[Galaxy S Plus I9001 Android Development] sir mordred:
Freeze problem on viber is related to kernel side audio drivers(qdsp5v2 driver)

And the issue is fixed with the following commit https://github.com/arco/samsung-kernel-msm7x30/commit/02f4cca3471dc191716f05c418d428b58943984e

Yes. I just figured it out. The K^Kernel 2.8 is compiled before that commit. So i think it does not contain that commit. Will have to wait for a new release. I could compile it my self. But I am on mobile broadband these days. Not enough data to download the required stuff.

of course I didn't have time and i update dirty over R11 :laugh::laugh::laugh: sorry pals :laugh: I did a clean install but the whole presets again was taking my one morning and I have some problems here so restored the backup of R11 and do a dirty job for R13 :D
