[Galaxy Tab 2 7" Android Development] daeinnor:
Noted. Thanks for continuously supporting TW roms with your kernel and keeping it up-to-date with F2FS support. I'm sure many appreciate it.
[Galaxy Tab 2 7" Android Development] PMikeP:
Same here on the thanks. v3.3 working fine. (More options than I can test! ;) )

Glad to see you decreased the default read_ahead values. I had settled on those values myself. (I use an aviation moving map program as my benchmark. I look to see how fast menus pop up as I dink with AGNi variables. Kind of a "user experience" benchmark.)

[Galaxy Tab 2 7" Android Development] PMikeP:
It benchmarked a little slower on AnTuTu, but otherwise, runs fine. (It had a sleep of death problem after the first run - first time that's ever happened on my Tab 2.)

I don't understand the purpose of the Aroma installer. Operationally, the Kernel flashes the same. (I enter Recovery, I install a zip, and it does it.)

Question: Should some options be greyed out on the ANGi Control? For example, when you select Hotplug CPU Governor. I was under the impression that Hotplug automatically deactivated cores. So does it makes sense to offer the Power Saving Load Balancer when Hotplug is selected?
[Galaxy Tab 2 7" Android Development] psndna88:
migrated to aroma for all devices so here too ... in future i may add some options in it.

power saving load balancer isnt of any beneficial use on dual core devices so keep it off , it doesn't turn on/off cores , it just attempts to put load more on one core so as to try not to turn on second core.

zzmoove-gaming governor seems to be better balance between performance n battery...

[Galaxy Tab 2 7" Android Development] lohtse:
Mines heaviely modified stock with your kernel....probably only loosely stock rom now.... taken time to get to point am very happy with it and don't really see much in the way of benifits with custom roms given the amount of bugs and hard ware issues I keep reading about. Have looked at changing on many occassions, Just prefer to have it as it is at the moment as its speedy, very battery freindly( get around 7+ hours uses a day)and rarely have FC's or other issues.. and better still no messing with setting specific dpi's for apps as they all simply work as is...

Show me a rom thats works like this and no hardwear issues and will reconsider changing...

[Galaxy Tab 2 7" Android Development] Qosmio-:
I agree, i use a stock rom modified xwdmk1 with agni 3.4 kernel great kernel btw, other roms has problems or missing things i need like importing calendar items, battery is also much better compared to none stock roms.
[Galaxy Tab 2 7" Android Development] cogbytes:
I was using SlimRom for last one year and tried CM11, omni, Paranoid and few other Roms too. Just for a change, I have installed Stock Rom with Agni kernel and it is going to stay for a long time now.

Not a single custom is comparable to the fluidity, speed and battery life of Stock Rom.
[Galaxy Tab 2 7" Android Development] PMikeP:
I agree with the others here. I've been running psndna's f2fs kernel on MicroDelta's stock based JB 4.2.2 ROM (P3110UEUCMK3), a slightly tuned stock ROM. (I haven't been paying attention, but I think 4.4.2 is the latest stock ROM from Samsung?) All the jokes about Touchwiz aside, my Tab 2 runs very well now that f2fs is here.

My Tab never crashes. I'm hesitant to flash a new ROM and go thru the hassle of re-tweaking all the settings on my apps. (Titanium Backup says it restores "data", but if that includes settings, it doesn't work for me.)

I don't know if there's anything else that needs to be done to the kernel - if it ain't broke, don't fix it. But just to let psndna know, we're still here, appreciating his work!

just re compiled with new toolchain
[Galaxy Tab 2 7" Android Development] PMikeP:
Thanks for this final update to the "old" Tab 2! I use mine as a backup moving map in an airplane, so reliability is important.

Your previous 3.4 build has worked excellently for me since the day you had it out. I don't mean to be the bearer of bad news, but unfortunately, this new version gave me problems during the install. (But see good news, at bottom.)

I installed it and wiped Dalvik and cache. The Tab stalled at 51 (out of 161) apps initializing. Maybe it got too hot? Either that, or heated up while stalled.

I rebooted, it immediately cooled down and finished updating. Then, when it started, it kept giving me a message that "the phone has stopped" (or something like that).

I managed to sneak in some touches between acknowledging that the "phone has stopped" message and rebooted.

Once rebooted, it ran without the message about the phone. While I was setting my old custom AGNi settings it crashed.

Reboot. This time I could run AnTuTu. But AnTuTu (v4) hung during the 3D stuff.

In the end, I wiped cache and dalvik and reinstalled the ROM again. (In that order this time, although I don't know why the order should matter.)

This time I put my Tab on an ice pack, to keep it cool.

It hung again during the application initialization, but completed after a reboot.

I was able to make it thru the AGNi settings without a crash this time.

AnTuTu runs to completion now, although for me, it doesn't benchmark as fast as the previous version. (9500 v 10500.) I might have to tweak some AGNi settings. (But see update, below.)

I know you're done building ROM's for this (I tried to download your beta release, but it's gone). I'm mostly wondering if any other users are having the same problems I had trying to install with this final build?

(Maybe I shouldn't have wiped Dalvik? I suppose I could restore my previous version and start over again.)

Update: I had forgotten that I had been o'clocking my Tab at 1.2 GHz. (Inconsistent with wanting the utmost in reliability, I know, but it has been running well o'clocked for months.) So I changed it to 1.2 GHz and now 11,100 on AnTuTu 4, up from 10,500. Woo-hoo! [That's running Hotplug governor, which works the best for me on this Tab 2 and my Nook HD+.]

Update 2: My install and initial run problems could be unique to me because I had used Link2SD to "incorporate" the latest Play services into system. (Saves memory.) Once I finally got the Tab up and running with your latest build, Play wanted me to re-accept Google's license agreement. That seemed odd, so that got me thinking that my merging of Play into system might have caused these problems for me.
[Galaxy Tab 2 7" Android Development] lohtse:
don't think is has anything to do with play store as ALL our devices(7 intotal) have asked to reaccept the license and we move update to rom too...

the issues you have mentioned may be your device specific as we have tab2 setup pretty much the same with agni's excellent kernel and no such issues as you have mentioned..

As to wiping dalvik cache shouldn't think that has anything to do with as I wipe the cache at least once a fortnight to clear junk left by apps..
[Galaxy Tab 2 7" Android Development] PMikeP:
Thanks for letting me know that you've not had any problems with the new ROM.

I didn't with the last version, so it's probably me on this one. (Although after getting thru it, albeit not smoothly, it is running well.)

After I submitted my original post, Play asked me to re-accept its license agreement on my Nook HD+ too. So I guess it must have been a coincidental change in Play. (I've never had to re-accept the agreement on a ROM update unless I did a factory reset first.)

Hi ...I know I'm off topic in this thread...and exuse me PSNDNA88

This is the only live thread about the Tab 2 and now, exuse me but I need to ask in here. Already asked in Q&A.....but nobody answer me.

My wife have a TAB 2 Gt-P3100 with jelly Bean 4.1.2 from Hong Kong. In the last week ( after 2 o 3 time the tab shut off.....and have some problem's) she ask me if I can root and put inside a stable Rom....Now are few days I ask in the Omnirom about all.....but nobody answer me.

My personal device is a Note 2 with Ketan rom....and I know what is necessary for install a rom in My device ( S-Pen....you know).

But....I dont know so much about Cyano and BABBQ etc.

I would like to install a Official build....and I feel the Omnirom is stable rom.

I already root the device and on this is the Philz Touch 6.40.4 Clockworkmod v 6.04.8

I know the step's for a clean install.

The external memory card is of 8 GB....

For the EFS BAckup....I can use the APP called GALAXY Sim unlock ? or this is another way raccomended for the GT-P3100?

The PA PICO GAPPS are right for this device?

Again exuse me for the off topic.

Thanks
[Galaxy Tab 2 7" Android Development] Qosmio-:
You can make a EFS backup with twrp (link on the first psn post) for p3100 dont use a app for other device.

I cant answer the GAPPS question as i only use Offcial build 4.2.2 for this device.

If you format system and data in f2fs and enable fsync script in agni app and install xplix from here http://xdaforums.com/showthread.php?t=2731670

you will not need to overclock your tab, Antutu score will be around 14.000 , with the new agni kernel you have a new device.

Cheers
[Galaxy Tab 2 7" Android Development] PMikeP:
Thanks. for the info.

I already had system and data formatted in f2fs.

Isn't fsync enabled by default in AGNi? I'll have to check.

Interesting to see the xplix info. I might try it. I know ad blocking works well in LiquidSmooth on my HD+.
[Galaxy Tab 2 7" Android Development] PMikeP:
Reset CPU freq before flashing?

I just reflashed the new kernel after restoring to my previous state. This time I reset the clock freq to stock 1 GHz before flashing. (Instead of 1.2 GHz before.) No hiccups this time after flashing.

[Galaxy Tab 2 7" Android Development] PMikeP:
Yikes! Tab hangs after formating /system to f2fs

So, I've been running v3.4 of this kernel since May. When the f2fs kernel came out, I formatted /data and /cache to f2fs, but thought I'd leave /system alone. (That is, I left it ext4.)

So, today, after running v3.5 for a while, I decided I'd go ahead and format /system to f2fs.

(Actually, I made two changes today. I also updated TWRP to 2.7.0.3.)

I used the special tool in the first post in this tread to change /system to f2fs. And then I reflashed v3.5.

My tab now hangs at the Samsung Tab 2 screen. No animation. (Don't even do the glow thing.) No nothing. (Also, TWRP tells me that my tab doesn't appear to be rooted and offers to add SU.)

I don't know how long to wait - I gave it a couple minutes. (Should I wait longer? It didn't get hot, like it does when it's locked up.)

I don't understand what's going on. I'm about to format /system back to ext4 and do a restore to get back to where I was.

But thought I'd post this in case anyone had any idea what's going wrong.

Update: I just reformatted /system back to ext4 and did a restore. Back to normal. (Whew!)
[Galaxy Tab 2 7" Android Development] Qosmio-:
Sorry to hear you had a softbrick, i read you flash only the kernel after you format system to f2fs but you need to flash a new system to not only the kernel.

Cheers
[Galaxy Tab 2 7" Android Development] PMikeP:
I took your suggestion and tried Xplix.

First off, I did an AnTuTu v5.3 test before trying Xplix. I got about 13,800 with the AGNi settings I've tweaked. So not too far away from 14,000 as it was. (It turns out I've had fsync enabled all along. The reason I was confused about its default state is because after I flashed the AGNi clean up zip, fsync remained enabled, even tho it says in the setup utility that "off" is the default.)

Then I tried Xplix. This is going to sound stupid on my part, because as soon as I saw what it did to my custom settings in AGNi, I restored my previous nandroid. I didn't even try benchmarking.

For example, it changed my governor. (And scheduler.) But I want to run hotplug or pegasusq, etc. And I run different cache settings that work for me.

After writing this, I might try enabling it again just to see how the AnTuTu score changes after I reset AGNi back to the way I like it, just to be fair about it. Who knows? Perhaps his other tweaks make a difference.

But as I said, I'm already at 13,800. And that's with hotplug, instead of performance governor.

The other issue I have with Xplix, which I posted over in its thread on xda, is that when I tried the ad-blocker install only, it STILL went ahead and changed my AGNi settings! :(

And I'm not sure that the ad-block is working. If it is, it doesn't seem to work as well as the host file in LiquidSmooth ROM.

---------- Post added at 09:56 AM ---------- Previous post was at 09:52 AM ----------

Yep, I believe you are correct.

I still have the micro-delta ROM I flashed on my SD card. But I'm not sure that it's worth reflashing the ROM just to have /system be in f2fs. I spent a lot of time uninstalling junk from the ROM, and I would have to go thru all that again.

But thanks for catching my mistake. I learn more from my mistakes than I do when everything goes well.
[Galaxy Tab 2 7" Android Development] PMikeP:
Anyone having problems with LMK minfree?

It's ironic. V3.5 of this kernel is so fast that I had to slow my CPU to stock. :) (Whereas with v3.4 I could run at 1.2GHz without problems.)

Anyway, I'm wondering if anyone is getting forced closes or reboots when you set LMK minfree to Light or Very Light?

I ran it set at Very Light with v3..4 and didn't have any problems. But I've been some FC's and had an SOD running Light on v3.5.

No, you do not have to format f2fs. (I left my /system ext 4.)

Technically, you shouldn't have to do a factory reset before flashing this kernel over the stock 4.1.2 or 4.2.2 Samsung kernel.

But if you're updating from a non-stock kernel, then you might have to reset.
