I'm still wating for franco to give his approval to publish it in here...
[Nexus 7 Original Development] paolocorpo:
OK

Is it good for TILAPIA too ?
[Nexus 7 Original Development] rapid_rabbit:
Mind sharing the toolchain you've used (also you got it from lollipop branch and used the conf from there right) ?
[Nexus 7 Original Development] espaciosalter20:
i have used latest christopher83's toolchain for cortex-a9 from this thread and tegra3_android_defconfig from HtcDreamOn lollipop branch.

Beware! disable ondemand and userspace governors or you will get compiling errors. check if, in some point, compiling stop at "fs/built-in.o"... pm if that happens to you

Anyway, here is the kernel modified with f2fs... i hope [MENTION=3292224]franciscofranco[/MENTION] doesn't bother for this (if you want it, i will take it down)
[Nexus 7 Original Development] paolocorpo:
i hav etried on TILAPIA and it is OK but ...

... i receive a strange message of memory full and i too much lag ...

I am checking better if it is just a startup issue
[Nexus 7 Original Development] rjmohit:
Is it? It would constantly crash the theme services or something on the 1/30 nightly along with frequent reboots. :/
[Nexus 7 Original Development] AgusL:
I have 1/28 nightly and I don't have any problems at all. System runs fast, it doesn't lag and I can even use Chrome without any freeze. Franco kernel makes it even better.
[Nexus 7 Original Development] rjmohit:
Do you plan to upgrade to the latest nightly?
[Nexus 7 Original Development] AgusL:
Give me a moment and I will flash latest and report here how it runs.
[Nexus 7 Original Development] fran_xda:
I have the same problem on 1-28 nightly... reboots all the time
[Nexus 7 Original Development] R3Lax1:
Yep, themes crash and the tablet keeps rebooting on 1/30 cm nightly.
[Nexus 7 Original Development] AgusL:
Flashed 1/30 + wipe cache, everything runs great. Then flashed franco kernel and everything runs great too. I don't know why you have problems. Did you try with clean flash?
[Nexus 7 Original Development] Doo Doo:
Would anybody happen to have this kernel (boot-grouper-r76-fixed.img) that osmOsis posted awhile back if yes please post it
[Nexus 7 Original Development] rjmohit:
Clean flash is a pain, restoring everything takes a lifetime plus I can do w/o Franco kernel till it's fixed. We never had any problems till KK, now multiple ppl reporting the same issue, wonder what CM did again to cause the incompatibility. :rolleyes:

Installed on rom costum Synman LL on Tilapia

The issue of drainage of battery in standby caused by wakelock baseband is not fixed ....

Inviato da Lumia820 con Tapatalk
[Nexus 7 Original Development] joaopaulo_:
Is a ROM issue, cause on rastpop I don't face it.
[Nexus 7 Original Development] paolocorpo:
For sure ...

Iti is a issue (just for TILAPIA/NAKASIG verison) of rom stock from JB, reduced with KK and remained with LL

Any other custom rom and their bundled kernel (with some execption as RASTAPOP ... :) has this issue

CARCOSA kernel is able to fix it (for sure .. i tried with LL rom )

FRANCO kernel is able just to reduce it ...

For this i am asking to Franco to introduce this fix as CARCOSA does
[Nexus 7 Original Development] gordonbennet:
Is the r81 kernel compatible with Slimkat 4.4? Thanks franco!
[Nexus 7 Original Development] khaytsus:
It's for 5, so, no.
[Nexus 7 Original Development] poppienutshell:
I just flashed r81 over a fresh PA beta 4.6 and somehow it won't boot anymore. Am i missing something?

Edit: oh sorry i just saw the previous post. I didn't realise r81 is for 5.0. My bad, please ignore.
[Nexus 7 Original Development] rapid_rabbit:
Anyone has an idea why the kernel doesn't build successfully until ondemand is disabled? It makes me feel either the config or the source isn't updated ?

Apart from that works great - thanks [MENTION=3292224]franciscofranco[/MENTION] !
[Nexus 7 Original Development] espaciosalter20:

Would you or anyone else that downloaded the f2fs version mind reuploading? Im getting an error on Mega.
[Nexus 7 Original Development] pride007.2012:
thank god franko is back with LP.
[Nexus 7 Original Development] franciscofranco:
Alright r82 is up and ready for grabs. Besides merging 5.1's commits and ramdisk I also added support for F2FS and it mounts /data and /cache if they are using that file system. Also added my share of improvements to kiss goodbye to the lag. Enjoy!
[Nexus 7 Original Development] JerryPi:
Thanks Franco, it works great on stock 5.1 with data and cache formated to F2FS. A small donation is heading your way as a token of my appritiation for your support and implementation of F2FS :cool:
[Nexus 7 Original Development] franciscofranco:
Thanks. I was wondering if F2FS auto-mount was working - I'm glad it is.
[Nexus 7 Original Development] Gundabolu SC:
EDIT- Sorry my bad.
[Nexus 7 Original Development] Fobos531:
How long does it usually take to boot when flashing the kernel?

These were my steps:

1) wipe cache and dalvik

2) flash kernel zip

3) execute flash-all script for stock 5.1 installation

4) boot up, set google account

5) reboot, flash twrp recovery

6) change data and cache to f2fs

7)changed my mind, reverted back to ext4

8) right now booting.

Did I do everything correctly or what?
[Nexus 7 Original Development] Spannaa:
Device usually boots straight away when you just flash the kernel, but you didn't just flash the kernel!

FYI - step 3: running flash-all will overwrite the kernel you installed in step 2

The WiFi sucks in CERTAIN parts of my house. Is it only me or someone else is experiencing the same problem?
[Nexus 7 Original Development] Spannaa:
Not sure anyone here has tried using wifi in your house...
[Nexus 7 Original Development] franciscofranco:
As quoted above no one knows how Wi-Fi works in your house, but jokes aside Wi-Fi drivers are 100% stock. Chances are this chip is not strong enough, you know, its almost 3 years old, things have evolved a lot since then.
[Nexus 7 Original Development] shawnbrennan55:
Working great for me as well on stock 5.1 with only /data formatted as F2FS. Thanks [MENTION=3292224]franciscofranco[/MENTION] !
[Nexus 7 Original Development] shawnbrennan55:
I believe only /data and /cache are supported as F2FS. Everything I have read suggests that there is not much to be gained by formatting /system as F2FS since it is a read-only partition.
[Nexus 7 Original Development] Fobos531:
Quick feedback: Your kernel + Stock 5.1 with /data and /cache formatted to f2fs. Beautiful. Thank you.
[Nexus 7 Original Development] snowfire88:
Bootloop?

I was on stock 5.1. I flashed twrp, formatted my data and cache to f2fs, then flashed supersu and then this kernel. Now, my device won't go past the Android bootscreen. Can someone pint out what I did wrong please? :confused:

Edit: Tried doing it again, and it booted after 5 mins this time! :D
[Nexus 7 Original Development] muxaba:
Is there a latest for KitKat branch version with F2FS support? Or, maybe, someone can build it?
[Nexus 7 Original Development] franciscofranco:
The Age of KitKat is over. The time of the Lollipop has come.
[Nexus 7 Original Development] Dodgexander:
It was mentioned a while back but I have encountered the error again with v81 on the latest PA release.

Stock kernel works fine, but installing a theme causes failure and device reboot. Accessing themes in settings causes a "theme services has stopped working" message.

Not sure if this is the place to report it, I did look for an official bug report procedure but couldn't find it.

I know on my nexus 5 there was a problem with themes similar to this, it was fixed in the latest release. Is there any way I can help getting this fixed? Of course I have already tried clearing cache, fresh installs etc the problem isn't there with stock kernel!
[Nexus 7 Original Development] fozzie:
You should attach/link your last_kmsg log file. (http://xdaforums.com/showthread.php?t=1520508)
[Nexus 7 Original Development] Dodgexander:
I have attached the kmesg straight after the reboot upon installing a theme.

I also attached the logcat copied from when themes provider crashes.

Hope this helps!
[Nexus 7 Original Development] poondog:
This kernel is made with stock Rom in mind; theme chooser needs additional sepolicy changes

I believe Franco's sepolicy is stock on this regard
[Nexus 7 Original Development] franciscofranco:
Yup.
[Nexus 7 Original Development] Dodgexander:
Will that ever change? On my n5 I'm using franco and the same pa build and themes work great.
[Nexus 7 Original Development] franciscofranco:
I have to add some ****ery onto sepolicy and the ramdisk, but sure, I can do that sometime.
[Nexus 7 Original Development] Dodgexander:
That would just be awesome!
[Nexus 7 Original Development] muxaba:
Lollipop is the future, sure. I'm using it on my Nexus 5 for a few month with no issues.

But for Nexus 7 2012 it's too early to move on. I have used CM12 on my tilapia for a week and was disappointed. My device became too laggy and unresponsible. Maybe there are some fix for this in Android 5.1, don't know since there is no build for tilapia. And LP has no killer feature that KK don't.

So, now I stick to 4.4.4 custom ROM with F2FS. Using it with M-Kernel, this kernel has F2FS support. But I'd like to have franco kernel with F2FS for KitKat. This kernel always was much stable and smoother for me.
[Nexus 7 Original Development] homerograco:
I manually flashed the 5.1 factory image and finally the tablet became usable. I've tried many ROMs in past, but 5.0.2 was simply too bad... my grouper was even slower than my old Nexus S on CM11.

So far, I haven't had the random slowdowns / lags, I am using Franco`s r82 + f2fs on cache and data.
[Nexus 7 Original Development] franciscofranco:
r82 ressurects Grouper from the dead :)
[Nexus 7 Original Development] JerryPi:
Yeah my n7 runs great with a simmilar combo for almost a week now ? I just have one gripe with the kernel, the min brightness is to high for comfortable night time use. Is there any way to tweak it manually like i can on my n5?
[Nexus 7 Original Development] franciscofranco:
Didn't I add something to allow lower brightness? Or that was for Flo? **** I don't remember. I have a vague idea about searching for the backlight code and not finding jack squat. I'll give it a whirl.
[Nexus 7 Original Development] JerryPi:
Yeah i use fku for setting the kernel up but there is no backlight minimum brightness under kernel settings like there is on the n5. When i was using Metallice kernel i could lower the min brightness by myself to a comfortable level with the trickster mod app. I would really appreciate if you look into it when you have the chance, tnx :) By the way i don't know where that question mark came from in my previous post, it was clearly meant to be a statement of how contend i am with my device not a question. Damn this new xda one app :D
[Nexus 7 Original Development] homerograco:
Yes, lower brightness would be great!
[Nexus 7 Original Development] HeikoE:
I installed r82 on my N7 wifi and it caused errors after reboot :

I had persistently returning the message "Telefon wurde beendet" ending in a complete crash after some OKs.

I didn't know, grouper has a built-in phone. What could be the cause of that?
[Nexus 7 Original Development] spica123:
Don't think it is kernel related. I had the same problem on euphoria and slim lp but only rastapop is working well.

Nevertheless the performance of 5.1 is nowhere near the speed of Mahdi all2fs and Franco kernel. Gonna downgrade if I find the time.

You don't, I don't allow overclock. I've been around for a long time, I know what happens when I add overclock to a device - some users decide to **** something up and I have to take the **** for it. Sorry, not happening.
[Nexus 7 Original Development] franciscofranco:
Depends - who can guarantee me the device's performance won't be affected with this? AFAIK higher dithering quality means the GPU has to work harder, and probably higher bandwidth to go through the whole display pipeline (correct me if I'm wrong). I don't wanna **** this device's already ****ed up performance.

Is it possible to convert to F2FS without formatting data?
[Nexus 7 Original Development] manulemaboul:
Nope, you can't change the file system without formating the partition with the new FS.
[Nexus 7 Original Development] suku_patel_22:
I am assuming f2fs works with Franco?

Sent from TheSixthDimension
[Nexus 7 Original Development] gogol:
Yes, but it requires the /system partition with ETX4.

So, you can have /data and /cache with F2FS, but not /system.
[Nexus 7 Original Development] pankaj_GB:
can i use it on tilapia????
[Nexus 7 Original Development] jonny68:
They may as well as stopped as Lollipop has rendered it almost useless, with your kernel and Rastapop ROM with Nova it's an improvement but on the grand scheme of things Android L has been a disaster for the Nexus 7 in contrast to other devices where it's running smoothly this might be a few years old but surely it's still optimized for Lollipop .

I'm going to try F2FS as a last throw of the dice if that doesn't solve the lag and stuttering then back to KK for me and I'm finished flashing or tinkering with the nexus anymore.
[Nexus 7 Original Development] tcat007:
I find mine runs as good as it did when I bought it (which wasn't all that fast). Purity 5.02+M74 (although Franco 81 isn't bad either) + Banks Gapps. Waiting for Purity 5.2 to move to Franco 82. All ext4, so I assume if I took the time to go f2fs it would be even faster.
[Nexus 7 Original Development] MikelFuchs:
I am facing again and again a problem with "Unable to stat ..." file errors in TWRP:

My Nexus 7 has stock ROM Android 5.1 and franco.Kernel - r82 installed. I used TWRP 2.8.5.1 to convert the data and cache partition to F2FS, then I restored my apps using Titanium Backup.

When I try to do a backup in TWRP after working for some time (can be some hours or a day) only the system partition can be backed up, but the backup of the data partition fails due to one or several errors like "Unable to stat /data/app/xl....tmp" which is already shown in the log directly after booting to TWRP.

In the TWRP File Browser I cannot delete these files, even I do not see them when using a root explorer in Android.

Also repairing the data partition in TWRP fails and wiping the data partition in TWRP is not sufficient to get rid of these files, I have to change the file system to ext4 and back to F2FS so that the data partition gets formatted.

Anybody has a clue?

Which TWRP version are you using along with Android 5.1 and franco.Kernel - r82 ?

Many thanks for your advice.
[Nexus 7 Original Development] boroboy69r:
I face the same problem on my n7 1st gen restored backup, i got no mods or anything installed just pure cm12, mine reboots OK n its self after the fc comes up a few times
[Nexus 7 Original Development] HTCDreamOn:
[MENTION=4207265]boroboy69r[/MENTION] [MENTION=4183187]HeikoE[/MENTION] if you're both using cm12 that would vr the reason you're getting errors. Franco kernel is for AOSP only, CM uses a different ramdisk and also has lots of changes to the kernel itself which franco may/ may not care about & implement. Either use AOSP or modify Franco to work with CM12 (I don't know how personally).
[Nexus 7 Original Development] boroboy69r:
Gess i will have to look into a aosp rom ?
[Nexus 7 Original Development] HeikoE:
I didn't read all details... I was on Purity ROM which is 5.02. R82 is for 5.1, only. Now installed Rastapop and this works great with R82.

android 5.1 f2fs apps issue

Hey [MENTION=3292224]franciscofranco[/MENTION] many of us are running your kernel and f2fs on android 5.1 and it`s been great performance vise. But lately we are getting some random issues inside twrp recovery and also in android where some apps randomly stop working and they can`t be reinstalled from gplay and we get messages in twrp like "unable to stat" for those particular apps. Some even say that they can`t perform backups in twrp which is probably recovery issue.

I found another post describing the same issues on another device where the developers incorporated some sort of fix in the kernel and in the recovery. Is this something you could look into? Tnx :cool:
[Nexus 7 Original Development] Leraeniesh:
Do you experience this on stock 5.1 (no kernel)?

I second that. I'm facing this issue too
[Nexus 7 Original Development] mkiker2089:
It looks like this kernal overclocks the CPU to 1300 with multiple cores. Am I correct?

Can we get a kernal that pushes it higher? In the past we ran these at 2g with no reported issues. 2 just kills the battery but I'd like to run at maybe 1.6 to offset some of the lag introduced with 5+ versions of Android.

I have found that running a performance gov with deadline seems to help.

Not related to the kernal but I was getting a lot of "out of space" errors. I happened to wipe the davlik and noticed that fixed it. So far 5.1 isn't doing it. Was this a common issue?
[Nexus 7 Original Development] HTCDreamOn:
Franco will never support OCing, explanation was in the OP previously but is no longer there for some reason. But yes I think this kernel does allow all cores to run at 1300MHz rather than 1200MHz as stock does. And of course performance governor helps, it locks all cores at 1300MHz but good luck lasting a day like that. You may have better results with cfq scheduler as its default and optimized also.
[Nexus 7 Original Development] Leonhan:
Hi, Im just new to using your kernel. I downloaded the FK updater app, but the cpu and governor settings dont seem to stick after a reboot. Anyone can give me tips on how to make it stick?

I know with stock Lollipop that the setting is there
[Nexus 7 Original Development] bass0324:
Hi Franco, love your kernel, use it on all my devices. Without devs like you I wouldn't love my android devices nearly as much.

I have two questions for you:

1. How do I go about building your kernel from source and creating a boot.img?

2. Mind if I use your kernel as a base to include the necessary code for USB OTG + Charging support and other misc usb rom features so I can continue to use the latest android in my in dash install?
[Nexus 7 Original Development] GtrCraft:
I have exactly that issue, or a file inside /data/system/dropbox gets corrupt or an app gets corrupted. It prevents me from backing up or wiping data. So it is a franco kernel or a twrp issue?
[Nexus 7 Original Development] HTCDreamOn:
There are many great guides out there, personally I recommend reading through a few to learn general methods from all so you get a better understanding of the whole process. Have a read of these: XDA Uni, the NDK-way, quite a concise & general squish of info.

Make sure to setup Git first tho!

Also you want to use tegra3_android_defconfig when you get round to it.

To make the boot img you need boot img tools, PM me if you get to this stage and are stuck. Also PM me at any point if you are unsure about anything in the process of setting up Git, syncing, compiling, etc. :)

NB About point 2, as Linux is licensed under GPL you can do whatever the **** you want with it for what you intend, unless you plan on releasing to the public in which case a) if it's only sources you're still fine cos GPL or b) if you're gonna release a flashable zip then getting francos permission would be a good idea.
[Nexus 7 Original Development] bass0324:
Thanks alot! I will look through those guides and resources. I have built aosp from source before, but it has been a while since I built a kernel from source on its own (last time I did that was on my nook color). I will give building it a shot and if I have any issues I'll be back :)

[Nexus 7 Original Development] elwood:
I quoted you on RASTAPOP but figured i would here as well. I don't think its kernel and twrp related as I use this kernel and the latest TWRP with Chroma ROM and data/cache both formatted to f2fs. As i suggested for thought maybe after formatting them to f2fs you could flash a cwm recovery and flash RASTAPOP, gapps su and franco, then boot up, set up, reboot to recovery and flash back to TWRP since only twrp supports the change of ext4 to f2fs. Again just a thought
