One qick request...plz post how u take logcats....so that other people will also follow it...i cant reply every one with how-to.....
[Galaxy Grand Duos i9082 Android Development] RIPPER:
1.5 version is stable
[Galaxy Grand Duos i9082 Android Development] Darian71:
HELLO EVERYONE. On request from k2wl, I am posting how i manage to record a dmesg log for our favorite kernel with an app from the playstore provided a couple of pages back.

https://play.google.com/store/apps/details?id=com.tortel.syslog

In the OP of UNOFFICIAL CM 11 by pawipt, he explains the log must be taken immediately after the random reboot for kernels. Not before, unless you can force a reboot, in which case you should use logcat, or catlog which runs as you use the device.

This app will give you the options to send/share the log once you've chosen the type of log you want recorded. However, when I shared to my Google Drive account, I couldn't get the log link to work when I tried to view it. So I simply email myself the log to my Gmail account, then open the email, click on the little dots on the right side of my attachment, and click save. Your log will then be downloaded to sdcard 0. I then open my media fire app, and click upload file. Navigate to downloads on the sdcard of my device, and click on the downloaded log I have named whatever I chose from the log app. You'll see where you can name your log once you've opened your sys log app. Or you can rename it once it's uploaded to you're media fire account. From media fire, I simply click beside my log, and choose copy link to my clipboard, then paste it in our forum.

I've seen much less complicated ways people have pasted their logs with other apps, but I don't know how. This works for me, plus the free media fire account let's me backup my favorite kernels, apk's, Roms etc. If anyone finds an easier way, please share.

In the screen shots below you can see the option, top left checked for kernel log, and down below the big "Log" button, there is a line that reads Crep......., with options to choose, last kernel, kernel, main, etc. I have used kernel and main. It just depends on what our Dev prefers as to which one to choose. But so far looks like using the "kernel" option is recording usable information.

If anyone has a question on something I may have forgotten to include, just ask. Will be happy to help us all, help our Devs improve on our beloved Grand. Thanks! And thanks to [MENTION=1883690]icehot[/MENTION]guy for the great app link.

RR v5.0.4 Running you're v1.2 kernel, enhanced with Ram Manager Pro from the playstore, set to Hard Multitasking with 8mb swap! Wooo HOO! You're kernel bumped the stock kernel by 350 points with awesome 3D graphic scores. :thumbup:

Thanks...

can u try new version 1.7.3 and tell me if that fixed reboot issue...

NO reboot on RR latest build (on defaul configaration)

Great work k2wl ,,, awesome man

only one question what about dual boot ( NO ETA :cowboy:)
[Galaxy Grand Duos i9082 Android Development] adi1996:
What is that 8mb swap??
[Galaxy Grand Duos i9082 Android Development] ##W4TCH0UT##:
It is an option found in ram manager pro.

And on rr 5.0.3 using evolution kernel 1.5

Sorry k2wl, will try it today. So far looks like everyone is doing well with it. :thumbup::D
[Galaxy Grand Duos i9082 Android Development] skpadhi79:
its been more than an hour....no reboots till now...bluetooth sharing and wifi/playstore downloads are all working......hoping it cud be as stable as 1.2..although had not tried.....on RR 5.0.4...:good::good:
[Galaxy Grand Duos i9082 Android Development] Darian71:
Been nearly 2 hours for me with v1.7.3 running RR v5.0.4 and NO reboots! Looks like k2wl removed the KSM. I think, because it no longer shows up under my performance settings on this ROM. I had disabled it on v7.1 and seemed to have less reboots then.
[Galaxy Grand Duos i9082 Android Development] k2wl:
i have disabled lots of services...i just need time to figure out what can it cause reboots,....and i am gonna take a little vacation from this kernel...as i want to focus on rom development now...

till then enjoy...i will be back with more kernel features soon...i promise...
[Galaxy Grand Duos i9082 Android Development] Donnalyn:
dont force yourself :) just take your time ^_^ we know you will be back soon with another great tweak . thank you for this awesome kernel [MENTION=943196]k2wl[/MENTION] ;)
[Galaxy Grand Duos i9082 Android Development] Darian71:

[Galaxy Grand Duos i9082 Android Development] raghavsharmaxda:
is it based on kernel that how long it takes to charge? :|

coz it takes very long time actually :P :|

i charger from 12 am to 3 am.... and 56 percent charge only!!

yeah...but the consumption is also slow and that makes it even :P :) !!!
[Galaxy Grand Duos i9082 Android Development] skpadhi79:
although i dont have a clear idea but somewhere in xda have read that slow charging is good for the battery in the long run..if the discharge is also slower......then thats great........isnt it...:good::good:
[Galaxy Grand Duos i9082 Android Development] jayc137:
As far as I remember it was said by either [MENTION=5406019]paulday[/MENTION]s or [MENTION=1152392]nasu[/MENTION]faldhyan
[Galaxy Grand Duos i9082 Android Development] k2wl:
Lithium - ion batteries needs to be charged slowly and if they discharge slow they will have better life...

in other words...less discharge cycles...longer battery life...

Source :- nokia 3650 battery information. ( 2001); my first smartphone.....first world camera phone...and my first phone...

My 5 yr old p500 still have its original battery with oxygen rom 2.3.3 on it...still takes 3-5 days to discharge...with my voice calls of 4-5 hrs, wifi, messanging, camera....etc....

still my best phone....

So summerize...battery life important for phone...and original battery is always better....

Franco one of the best kernel developer said "performance and battery life are main purpose of custom kernels....in his p500 kernel thread".
[Galaxy Grand Duos i9082 Android Development] Darian71:
On ALL versions of Evolution Kernel, I personally have found my battery to charge rather quickly. On home/wall charger, my battery will charge from 15% to 100% in 3-4 hours at most! And with normal use, which I text ALOT, calls, Internet and social media, I always get 8+ hours from full charge. My device is only 3 months old as I bought it brand new. ?
[Galaxy Grand Duos i9082 Android Development] RIPPER:
Perfect kernel. No reboots now. Loving it. And about charging my fone is taking 2.5 hrs to charge from 20 to 100.so It's normal :o:o thanks [MENTION=943196]k2wl[/MENTION]
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:
+1.

Also on the latest build benchmark test i got is around 10k

Than on v1.4 that i easily got 11k+

Though i know that benchmark test doesnt mean in real word performance.
[Galaxy Grand Duos i9082 Android Development] raghavsharmaxda:
I do prefer1.5 version as it got ksm thing working and also is kinda better with performance control app.....in this version..i change read ahead value to 4096..after reboot it resets :|.same happens in foregorund reading and all, i keep very aggressive and it resets back.!
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:
but 1.5 breaks bluetooth operations, as well as 1.4.

so if the user wants a:

(1) full functionality + high benchmarks, v1.3 is preferred

(2) full functionality + good benchmarks around 9k-10k score, 1.7.3 is preferred.

and

(3) No Bluetooth + 11k-12k bencgmarks, 1.4 is preferred.

EDIT: [MENTION=943196]k2wl[/MENTION]

performance control app is not applying the values i've set on it,

is it ROM or Kernel problem?.

also the latest kernel yields low benchmark points against

the previous versions
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:
Any fixes for the peeformance control app?

I think it is the reason why the kernel results to a low

BenchMark scores because it doent apply the set values.
[Galaxy Grand Duos i9082 Android Development] Donnalyn:
Agreed !
[Galaxy Grand Duos i9082 Android Development] ##W4TCH0UT##:
It applies on probam but not on RR. That's because RR doesn't let you apply the values.

And on rr 5.0.4 using evolution kernel 1.5

flashed v1.7.3 on cm11 lastest build and it is giving me a error of (android.phone) "something" has stopped and it was continuous and i wasn't able to use my phone..any help please?
[Galaxy Grand Duos i9082 Android Development] Donnalyn:

1) flash the kernel on my CM11

2) then, flash the FULL rom again on that kernel?

is that what are you saying?
[Galaxy Grand Duos i9082 Android Development] Donnalyn:
No . what i try to say is if you want solve the error problem , you need to reflash cm11 back . and one more thing , maybe evolution kernel not compatible with cm11 or probam . i tried to flash on both rom . still getting the error .
[Galaxy Grand Duos i9082 Android Development] ##W4TCH0UT##:

[MENTION=943196]k2wl[/MENTION]

Is USB-OTG possible? Its seems that the reason why the codes

on the official source are incomplete on the OTG Host mode is the hardware in the spec. Sheet of galaxy grand duos doesnt support

OTG Host mode.

Or we're on the same boat of Nexus 4?

Or its really that were have the hardware support

But the kernel and the rom is incomplete
[Galaxy Grand Duos i9082 Android Development] jayc137:
S2Plus supports OTG and also has the same SoC and PCB as Grand.

It may be as simple as just some commits/files or as hard as porting Android to HTC Mega.
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:

[Galaxy Grand Duos i9082 Android Development] RVR:
even OTG support?
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:
Still no OTG support. It will take time for it.

Also OTG must be present on the ROM+KERNEL+DEVICE.

we still dont know if grand has the enough power to be host.

Use the version u like! Kernel requirements doesnt very with rom afaik...unless u try this kernel on tw roms or non -kitkat roms ofcourse...

Any kitkat rom, u can use it, see changelog to compare and decide which is better for u..

If wanna revert to stock, simply reflash the rom(dirty flash may do it)..if u face problems or anything after dirty flash, clean install of rom is adviced...

Hope i helped :)

First of all thank you for this. This is still a fresh but very promising FS so it's nice to experience first hand what it can do:good:

I assume there would be shortcomings since its just introduced for the first time but I'm curious, how far is the F2FS implemented for us?

And is the segment size kept at 2M?

Despite the increased cache size, I think it should work great specially with right VFS values. And again, thank you, looking forward to trying it out tonight.
