[MENTION=4021423]ketut.kumajaya[/MENTION] I see 3 options about SmartReflex using Trickster Mod : Core, IVA and MPU. Default is off, but I can turn them on. Now will turning them on will benefit me ? Using Next 1.4.1 OC to 1.2 GHzon Stock ROM XXDME1.

I also edited init.post_boot.sh like this below.

Help needed ,i dual booted with jellybam v8 rom everything was working fine but as i locked the screen and after some time i pressed the lock button and it i took at least 10 sec to show up the screen and when i swiped to unlock it again took 8 or 9 seconds,now it is happening every time ,is it the problem with kernel or something else please someone help me i do not want to change the ROM ,it is sometimes happened with other ROMs also:(:(

I got different result with Antutu: CM faster than stock :D A lot of difference in I/O benchmark. So, Quadrant optimized for stock, Antutu optimized for CM :laugh:

Still not understand how Trickster detect Smartreflex, default on in nooc version (Smartreflex class 3 enabled). As [MENTION=4103418]Dexxmor[/MENTION] mentioned before, I got a strange issue after applying GPU 384MHz using Trickster (with Smartreflex swicth all off). A lot of app and service killed without warning, no force close message (browser, launcher, download process, message, phone service, etc, based on dmesg output).

On both 1st and 2nd ROM? Any dmesg output? Are you using Trickster?
[Galaxy Tab 2 7" Android Development] anjaykumar:
No i am not using trickster, and it is only on 1 st rom, 2nd Samsung one is working fine:(

Edit - I checked roms one by one cm, slimbean and pacman they are working fine no problems at all, i think the problem is with the rom, thank you for your response :D:thumbup:

exFAT or ext4 on sdcard

hey ketut i am curious about such an idea?

which one of the following will perform better for daily usage:

1. if i format whole sdcard as exFAT and use it in the tablet

2. if i format whole sdcard as ext4

the aim is to be able to transfer/download files larger than 4 gb and mainly to try to avoid the need of a laptop.

which one of these options will give better performance or daily usability with your kernel? (because it is said that exFAT slows the performance, ext4 has more write/read amount, which also can slow the system..?!?) just wanna try get independent of pc need as this tab is superior as daily companion..

For 1350MHZ change the voltage up by 50mv. Hit apply and then try overclock to 1.35 GHz and see if it works.

[Galaxy Tab 2 7" Android Development] Skazzy3:
Maybe your device cannot handle more then that.

My device probably can't either.

If your running on any rom other then AOSP3+ (That ROM needs a specific kernel) then you should try the DhollmenCM kernel and try overclocking past that, With that kernel I can OC 1.48 GHz np. Just don't change the voltages.

dualboot works with a AOSP rom and Stock roms?
[Galaxy Tab 2 7" Android Development] tuxafgmur:
Maybe, I don't understand this stuff here, but ...

1335 == 1350 MHz

1385 == 1420 MHz

1415 == 1480 MHz

I think above values are good enough, but a kernel is not only voltage adjustment.

Your kernel needs much more to work well with lower voltages

Another idea

Hey ketut what about such an idea :) what do you think, will it be possible to duel boot android and Windows 8 on our divide? ;)

Because everything seems good for me now, I just try to find some another weird idea that can be chased... :)
[Galaxy Tab 2 7" Android Development] Dexxmor:
I think Windows 8 needs a x86 architecture, we have arm, so...not possible. Windows RT ... mmh under some circumstances, but we have no ROM and nobody will build us a RT image. Its quit difficult to build Windows from Scratch, no drivers and no Source (and its illegal, Windows > Closed Source). So forget Windows.
[Galaxy Tab 2 7" Android Development] ts_firehawk:
It is illegal if someone posts the Windows RT for download here. Porting it to our device isn't completly illegal since the developer (in this case, ketut) would not provide the Windows files.

Guys, I'm not quite sure that it's ketut's kernel issue.

I am experiencing same heat issues with many custom roms using the kernel they provide.

I too hope there is a solution to that. In any case, it doesn't affect the tab's performance. Ketut's kernel is the best choice...
[Galaxy Tab 2 7" Android Development] Andrev01:
Two questions:

1) Today I went to Performance Control and I see that my CPU works constantly on 1008 MHz (on max) even when I'm doing nothing (just watching this cpu freq in Perf. Contr.). Is it normal? (on interactive cpu gov.)

2) Does anybody tested hotplug cpu governor? Is it safe and good? :)
[Galaxy Tab 2 7" Android Development] bluecarbon:
That is odd, I'm not experiencing any extra heat, and my governors are doing their jobs correctly, 300 when idle and 600- 1008, when in use and all that good stuff.
[Galaxy Tab 2 7" Android Development] Rotundjere:
nooc kernel is the best,

I warn you that if you use the oc kernel you may get bad luck & brick your tablet 2-3 years from now!

that is impossible,

because no device drivers, and you must reverse engineer the signed kernel (bootlock) on windowsRT, which is illegal. Ppl don't wan't to get jailed because doing that :)

if you still want windows8, I suggest you to buy new x64 tablet with Intel Atom processor (such as hp, lenovo). It's more cheaper that i5 or i7 tablet.
[Galaxy Tab 2 7" Android Development] yomiguy:
It would be a miracle if I still have this tablet after 3 years! ;p

It's awesome but I don't think I'll have it pretty much more than 3 years or even two. But who knows? The fact is that now it runs perfectly with 1200 cpu and 384 gpu :)

how about the voltage ??
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
Whichever version of this kernel does not overclock the CPU/GPU but you.
[Galaxy Tab 2 7" Android Development] yomiguy:
I don't use any app and neither I touch voltage, just cpu and gpu.

To change max freq of cpu you can do it in settings, performance, and cpu. I've set on boot 1200 mhz max freq, and untouched minimum freq.

To change gpu values here you are the instructions Luigi gave me some days ago

GPU clock gets changed in /etc/init.post_boot.sh.

Edit that file with a text editor and on the line where it says "#GPU clock or something like that on the line where it says "# echo 1 > blahblahyadayda/gpuoc" change it to "echo 1 > blahblahblah.

Remove the # to get cpu oc..

Finally reboot your tablet and go!

If you want to see how this file should look you can read post 312 where I uploaded a screenshot.

I Hope I helped! ;)

get android policy .jar from p3110 build

get the system ui.apk from p3110 build

so these files would be replaced

Additionally u can include a modified version of buil.prop in the zip
