Okay, so I've been testing this Kernel for a few days. Here are my observations.

My Tablet : Shield Tablet K1

ROM : Stock nVIDIA ROM release 1.5 (Android 6.0.1), TWRP 3.0.2.2, K8-001 Kernel

Others : Adopted Storage Sandisk 64GB UHS-1

1. Having another I/O scheduler helps, changing the default from no-op to deadline actually removed the occasional lag when accessing storage.

2. This is strange, but whenever I restart the tablet, I get the "System is not responding" message. There is also a chance that it will be stuck until the tablet reboots by itself, or I can dismiss the message. I still get this after factory wiping (wipe data, cache and dalvik) and reinstalling my apps. I feel this is going to be a problem when I update something (e.g. SuperSU, or a new Kernel). It also appears I didnt' need to flash the DTB file since I didn't encounter any issues regarding charging.

Overall, I like how the Kernel have improved my system. I want to try the KX8 regarding the overclock but I dunno if it'll break my SD card (I had all my games installed there)
[Shield Tablet Android Development] fuorionda:
Hi, I have tried to install kx8 over k8 on original shield lte stock 4.4 f2fs on cache and data, result was bootloop.
[Shield Tablet Android Development] boswelja:
Did you flash the DTB?
[Shield Tablet Android Development] fuorionda:
No
[Shield Tablet Android Development] boswelja:
Flash it and see what happens
[Shield Tablet Android Development] fuorionda:
Same results
[Shield Tablet Android Development] boswelja:
Oh.. not sure what could be causing this then
[Shield Tablet Android Development] BitOBSessiOn:
Ummhhh... Weird. F2FS support is the same in both versions so in theory this FS for /cache and/or /data shouldn't be a problem.

Have you wiped dalvik and cache after flashing?

Anybody else with this problem...?
[Shield Tablet Android Development] Dashwood Foxe:
Same problem here.
[Shield Tablet Android Development] gireza:
heloo all

i just got shield k1

never been in touch with kernel modification :D

so recently i read in k1 master thread that it has qc 2.0 compatible by flashing the dtb file

is it works?

and do i need to flash the k8/kx8 kernel too?

i'm in OTA 1.5 rooted MM 6.0.1 with stock rom
[Shield Tablet Android Development] sarmentoedu:
Can explain how to install this kernel? can i use twrp to flash?
[Shield Tablet Android Development] Son-j:
I did the same, no problem. Mine is unrooted. Just stock 4.4 with k8 upgraded to kx8.

Only problem is the occasional PHOTOS stopped, sometimes Google play would stop.

Occasional lagging persists, sometimes after a long sleep, sometimes randomly when you think that the tablet has normalized... Really, why does stock firmware have this problem? I've got no similar issues with custom Roms, only disadvantage with custom Roms is that I can't take advantage of Nvidia native apps like controller, stylus, game mapper, etc..
[Shield Tablet Android Development] fuorionda:
Do you have ext4 or f2fs file system?
[Shield Tablet Android Development] f0xG3:
The KX8 is actually nice and the OC is great! (Especially when OC-ing the GPU a bit). However, the adopted storage feature is broken :( . It formats the SD card but for some reason it reports corrupted afterwards.
[Shield Tablet Android Development] KentuckyGuy447:
Getting random freeze-ups with the lastest kernel. Flashed the dtb. Will also note I'm using CyanogenMod 13.
[Shield Tablet Android Development] fuorionda:
Ok, I tried to clean install the official 4.4 rom in both scenarios: ext4 or f2fs with K8 and KX8. K8 works well in both cases instead KX8 fails to boot on f2fs.
[Shield Tablet Android Development] BitOBSessiOn:
Ok, so... There seems to be something wrong with KX8 and F2FS... I will revise.

Thx.

EDIT: Prob located... fixing... building...
[Shield Tablet Android Development] BitOBSessiOn:
BitO-KX8-002 Available

Available here.

*F2FS and all tweaks should be fixed in this version.
[Shield Tablet Android Development] f0xG3:
Hey, the KX8-002 update now correctly mounts the Adopted Storage. Nice work :D
[Shield Tablet Android Development] xanthrax:
Confirmed!

entire userdata partition gets corrupted after setting partition to f2fs, it gets so bad that I have to fastboot format it since the partition locks itself.
[Shield Tablet Android Development] BitOBSessiOn:
Have you formatted to F2FS....?
[Shield Tablet Android Development] tinybilbo:
I've got 2 k1's...

I've also been having sporadic /data partition (F2FS) corruption on both pads...

One pad corrupts more frequently than the other.

Occasionally the data partition locks as well (on both).

A couple of reboots or a format from fastboot fixes it.

I'm on the latest BitO-TWRP-3.0.3-MROM-F2FS-shieldtablet-009 and BitO-KX8-001-shieldtablet (as well as BitO-K-F2FS-inject-shieldtablet). It has also happened with earlier versions of recovery and kernel.

I've formatted cache and data to F2FS.

I'm going to have format back to ext4 to make sure they are stable... which is a shame because they performed well when working....
[Shield Tablet Android Development] BitOBSessiOn:
Haven't you updated kernel to BitO-KX8-002...?
[Shield Tablet Android Development] tinybilbo:
Apologies, I have not.... downloading now.

Actually I meant K8-001, but I will try KX8-002 later tonight.

I will let you know how I fare... And thanks for the hard work!!
[Shield Tablet Android Development] Dashwood Foxe:
Yes I have
[Shield Tablet Android Development] Pariahnoble:
Are these linaro kernels still uploading or something? KLX is gonna purr..... Sorry I'm excited for this, don't mean to pester
[Shield Tablet Android Development] lupick:
Testing 017 kl on stock and all looks great
[Shield Tablet Android Development] BitOBSessiOn:
KL compiled with UBER's toolchain, based on Linaro 4.9.3.

KLX will come to us... anytime. Patience, please.

About lag in some apps... It's not a kernel problem, it's because system+app. Chrome, Facebook, etc... Are known to take system down... Are you wiped dalvik and cache after flash? My stock runs smooth with these apps... (I'm surprised), or the problem is in other direction...
[Shield Tablet Android Development] riganta:
I am now running KL 017 since this morning. Its running perfect. no issue to report.

Thanks for the great work, this is much appreciated.
[Shield Tablet Android Development] BitOBSessiOn:
What error do you get... ?
[Shield Tablet Android Development] riganta:
Wipped everything started from scatch. I am running CM 12.1 with KL 017. Excellent. No issue to report there. Thanks.
[Shield Tablet Android Development] Pariahnoble:
Well im not sure but I think there may have been issues before with 016 on 12.1 I noticed it was ALOT slower than stock, but the new kl build 017 on 12.1 is night and day better. I'm noticeably faster and smoother than stock now @ 1.8ghz lol O_O well effing done bitO this thing is slick. Only thing I noticed is that on 016 the "volume change sound" worked and it doesn't now. Same cm build new kernel. No biggie but thought I would bring it up. Any chance of getting row i/o scheduler and maybe the high-speed tcp from umbrellas? I'm pretty sure this thing would grow wings... Anyway thanks for making me like my tablet finally. Your attention to detail shows!
[Shield Tablet Android Development] BitOBSessiOn:
KLX-018 for CM available for testing in OC folder... Stock versions pending (probably tomorrow).
[Shield Tablet Android Development] alexmat:
NICEEEEE!

Just flashed KLX-018. Very smooth, no issues.

Running it on top of the CM12 rom. This is the tablet I was hoping for, thank you for making it happen!!!
[Shield Tablet Android Development] BitOBSessiOn:
KLX-018 Available

KLX-018 available for Stock / CM.

PS: Probably, I will reorder download folders....
[Shield Tablet Android Development] badagaio:
I think it's better. It's starting to get a little bit confusing: ;)

Incredible job with the latest kernel, no more slowdowns, not even after a long night on suspension.
[Shield Tablet Android Development] BitOBSessiOn:
Well.... kernel directory reordered. I think it's easy to understand.... ;)
[Shield Tablet Android Development] riganta:
running KLX-018 on CM12.1. Only one word - Excellent.

Thank you for your hard work. it's much appreciated. ;)

Let me know if there is anything I can do to help.

BTW: I have a European LTE shield for those who have doubts as far as flashing CM12.1 with 018.

All the best,
[Shield Tablet Android Development] matlear:
Hello, can you tell me which version of your kernel is available for stock 4.4.2 ?
[Shield Tablet Android Development] BitOBSessiOn:
Sorry, no version available for KK, only LP. I've tried to compile for CM11, but no trivial... I prefer to focus in latest Android versions.
[Shield Tablet Android Development] duanim:

Thanks Bito you're great

Stock and klx running perfect

Flashing v18 KLX on 2.2.1 OTA, from v16....good work BitO!!!!
[Shield Tablet Android Development] Pariahnoble:
I don't want to burst bubbles, but, I've been running games and movies all day on hdmi with the ovdeclocked kernel and the overclock fried my hdmi output, it's toast, flashed back and forth to stock stock, and I now only have half a screen and my tablets screen flickers when hooked up to hdmi. Tried it on different tvs and an hdmi adapter. The oc heats up the gpu hot as hell even @ 1.8 ghz cpu. I knew the risk but damn. Heads up.
[Shield Tablet Android Development] dzefo:
i try BitO-KLX-018-OTA2.2.1-wx_na_wf cpu is only 2.4GHz
[Shield Tablet Android Development] BitOBSessiOn:
Perhaps so much time GPU at 900MHz... We can try to limit GPU to a lower value... Sorry so much, I hope problem gets solved... I have suffering flickering in some tests, but after turn off for a while and flash a stable kernel problems go away... Good luck.. Let us know...
[Shield Tablet Android Development] tinybilbo:
I have updated as well now...

I must say the pad that the was frequently corrupting has in fact stabilised and allowed me to install xposed.

Before, every time I installed xposed it would corrupt (the other pad would install it without corruption).

So I'll run the pads for a bit and see what happens..

However so far so good!!!

Many Thanks and Merry Xmas!
[Shield Tablet Android Development] coowkeee:
Flashed kx8.. Smoother than the stock for sure. It works on first flashed with sd card working last night. But now, random reboot then SD card not working again.

I'm playing clash Royale, while typing the game glitches for the first time, then I restart it again same thing happens. After that, on the app optimization I changed optimize system memory to off, then no glitches but it froze and reboot with corrupted SD card.

I restored my K1 twice and sd card still not recognized.

Will flash again if it will fix it.

Edit: Flashed the KX8 v2 again and it's working fine again.

BTW, im using Optimized plan and only 2cores 100%+ Optimize System Memory 'ON'. Tell me if i'm doing it all wrong. Thanks

Edit 2: Froze again with facebook app this time.

Edit 3: Just restored my backup. Really want this but keeps freezing on some apps the reboot with corrupted sd card, but if this works for you, you're lucky.

K1, rooted M, with xposed 86
[Shield Tablet Android Development] winesh:
I see that the last updates are only made for kx8, and not for k8. Does this mean that k8 will not be maintained anymore and is obsolete?

What would you advice people who don't want an overclocked tablet, stay with k8 or just move on to k8x since it is the better and up to date one?
[Shield Tablet Android Development] primaleph:
Would it be safe to use this kernel with a 7.1.1 ROM?
[Shield Tablet Android Development] BitOBSessiOn:
K8 will be updated when needed. Not obsolete... Same functionality that KX8 but no OC.
[Shield Tablet Android Development] BitOBSessiOn:
It shouldn't break anything... Backup boot partition before flashing, please...
[Shield Tablet Android Development] primaleph:
I did. It worked, but without any of the additional IO schedulers I was expecting. Not sure if it was working as expected otherwise.
[Shield Tablet Android Development] BitOBSessiOn:
Ummhh... I will revise... Thx for feedback.
[Shield Tablet Android Development] primaleph:
Np. Are there any logs that would be more helpful to you? I'm running the Dirty Unicorns 11 release candidate from 12/23 currently.
[Shield Tablet Android Development] Fidelator:
Guys, how has your battery life been? Could you post screenshots of your SoT? This is the only android device I've owned that I've yet to tweak because of the great degree of control Nvidia gives us but I find the battery life lacking, my SoT is usually about 6 hours.

Also, does this support undervolting?
[Shield Tablet Android Development] Lawlrus:
Sot is a terrible way to gauge how a kernel or ROM will work for you.

If I do nothing but use my tablet as a kindle to read, and you game, how exactly is that going to tell you anything? Why not make a backup and run it for a week?
[Shield Tablet Android Development] Fidelator:
I don't want to void my warranty without a good reason to do so, I bought this like 2 months ago
[Shield Tablet Android Development] Lawlrus:
Guess that's a good reason then, I was under the impression since you were posting the BL had already been locked. Then again, less this tablet is different than phones, which I didn't look into (I actually unlocked and flashed mine a couple hours after I got mine) shouldn't you be able to flash the stock images and relock the BL if you end up having mfg defects?

Either way, if thats the case, your best bet would then be to ask if anyone uses their tablet to do x, has anyone noticed better battery life on this device on y ROM or z kernel, if that makes sense?

Might give you a more realistic opinion versus trying to base it off sot
[Shield Tablet Android Development] Friedensfurz:
There is no flash counter, so you can just go back to stock rom and lock the BL. Nvidia is also very repair-friendly, as long as your tablet didn't die from overclocking etc. they will usually repair it ;)
[Shield Tablet Android Development] coowkeee:
This is weird and good lol. This morning I flashed the kernel again and on kernel auditor I set gpu on 984mhz it means it's oc then set apply to boot. After that my k1 reboot and corrupted my SD card again, then I restore my boot and system(because I don't know where the kernel is, lol) and in my surprise when I looked on the kernel auditor again max gpu is set to 984mhz and minimum 852mhz, theres no option to set it on max 984 so I'm happy it retains it.
[Shield Tablet Android Development] mrbazil:
I have some Bugs with the K8 Kernel.

First i flashed the newest version of Bliss Rom on my Nvidia Shield Tablet -->No bugs, but the device was awfully laggy.

After that i tried flashing the k8 Kernel.

The Device runned really smooth but after some time using the Device Youtube/Netflix Videos glitches (it looks something like this https://goo.gl/frBiWN),

chrome often only shows a almost black website (even after refreshing), some apps keeps crashing (Super Su, Kernel Auditor Mode, Chrome,...) and/or the device restarts without a reason.

Did i do something wrong?

Did i forgot to flash something?
[Shield Tablet Android Development] Fidelator:
How has your battery life been? Say in a light use scenario, general browsing the internet, using YouTube, checking emails and that kind of things, around what brightness % did you achieve such a SoT, or just describe you usage and battery if it isn't too much of a problem.

And guys, does this support UV'ing?

Thanks.
[Shield Tablet Android Development] supertory:
Ive had the video glitches as well even on twitter, snapchat and with native videos
[Shield Tablet Android Development] mrbazil:
Had?

What did you do to fix them?
[Shield Tablet Android Development] supertory:
i just returned to the stock DU kernel sorry for the misunderstanding
[Shield Tablet Android Development] mrbazil:
Sry for asking, but what does "DU" stand for?

"Dirty Unicorn"?
[Shield Tablet Android Development] supertory:
yes it does :)

[Shield Tablet Android Development] dvdivx:
Any chance of a security update for this and bliss to cover the December patches? A lot of NVidia security problems were fixed along with the dirty cow exploit.
[Shield Tablet Android Development] BitOBSessiOn:
Yes... Pending.
[Shield Tablet Android Development] ctap001:
do I need to flash the F2FS injector even if I format to F2FS through TWRP?
[Shield Tablet Android Development] BitOBSessiOn:
Yes, you need it for proper booting after format.
[Shield Tablet Android Development] ctap001:
Thanks. You think this kernel would run on 7.1 roms, like Carbon?
[Shield Tablet Android Development] dvdivx:
I would really doubt a 6 kernel would work on seven. Aside from no Xposed support, seven is just too buggy right now for me.
[Shield Tablet Android Development] winesh:
Does this kernel support double tap to wake, considering the weak power button we have?
[Shield Tablet Android Development] xanthrax:
Nope that's not easy to implement, other things gets broken, use the stylus remove to wake up

Sent from my Darkside of Oneplus 3
[Shield Tablet Android Development] winesh:
I have the k1 without stylus unfortunately. I have seen some apps on playstore that allow double tap to awake with root. Can anyone confirm if this will work, or is it also kernel dependent.
[Shield Tablet Android Development] xanthrax:
Kernel dependent pal
[Shield Tablet Android Development] Pfeffernuss:
I have (well, had) it kernel-enabled on my Nexus 7 but switched it off due to additional battery consumption.

When using the tablet a lot it won't make a lot of difference but I rarely use it and the idle-time was cut in halve, with DT2W enabled. Not really strange of course, just mentioning :good:
[Shield Tablet Android Development] BitOBSessiOn:
You can make a TWRP backup for /boot and try... Share your experience, please.
[Shield Tablet Android Development] Paolo ponzano:
[MENTION=6411851]BitOBSessiOn[/MENTION] can you please add those things to the kernel?

-Maple scheduler

-Dynamic fsync
[Shield Tablet Android Development] BitOBSessiOn:
As a main line I prefer to keep things as simple as possible, so if not a huge improvement is present, probably the feature hardly will be included... Dynamic fsync switch feature was included at the beginning but it was abandoned in later versions...

I'm studying include some features for future versions... Will see...

Thx for suggestions.

I'm still having problems with pad(s) and F2FS?

One of them had been off for for a few days,, and when I powered it on it reset and went through setup again although it retained its apps. A couple of reboots later it reset again only this time I lost its apps...

This is basically stock firmware with Bit0 kernel.

The only mods are F2FS and xposed..

Is anybody else having issues with F2FS?
[Shield Tablet Android Development] BitOBSessiOn:
Are you sure the culprit is F2FS and not Xposed... ?
[Shield Tablet Android Development] tinybilbo:
No I'm not sure, which is why I mentioned it... :)

I thought somebody (who either does, or not have it installed) might also have issues, so as to narrow it down..

However I am currently testing without it...

BTW Thanks for your hard work... :)
[Shield Tablet Android Development] Son-j:
Hi. I'm currently using BT-kX8-2 with stock 4.4, unrooted. For the past 2 months I am able to observe regular unmounting of SD card. Happens to both 64gb and 128gb card. Wondering if others are experiencing the same or have any idea what could cause this. I only got to experience this with kx8-02. Didn't have this with kx8-01 although the latest is quite smoother.

TIA.
[Shield Tablet Android Development] DR_HAX34:
I've been using F2FS on my Shield Tablet on Stock NVIDIA and I see no issues... Never lost any app too...
[Shield Tablet Android Development] tinybilbo:
I too have had problems with F2FS and losing data on reboots (going back to the setup).

I also had xposed installed.... I have since tried it without and have not had a major issue (a couple of freezes, but no data loss).

Try without xposed and let us know how you get on... It'll help narrow down if xposed is the culprit
[Shield Tablet Android Development] n3xus22:
First of all, congratulations on this great work. I have a question and it is, how can I do root once the kernel is installed and working? Is that I use the latest SuperSu.zip and I have the tablet in Bootanimation

Enviado desde mi MI 5 mediante Tapatalk
[Shield Tablet Android Development] BitOBSessiOn:
You shouldn't have any problem flashing latest SuperSU zip after (or before) kernel zip...
[Shield Tablet Android Development] n3xus22:
Well, I do not understand what happened. I will try again later. I have the last nightly of CM. Thank you

[Shield Tablet Android Development] Son-j:
Hi just tested KE8 for the past 2 days. Here are my observations:

- seemed faster/smoother than kx8

- occasional PHOTOS, google apps, system crash/FCs

- occasional lagging after deep sleep

- occasional unmounting of SD card (observed also in kx8, but none in k8)

- removes sounds in controller headset (not observed in kx8. when I reverted to stock, sounds went back again)

Thanks for your efforts :) wish I could supply you with logs but I don't know how to do that yet. So I'm sharing these observations maybe others have similar or different experiences as well.

For the Nth time, can someone tell me what causes deep sleep lags or even lags that just happen while you're playing with the tablet? Even at GeForce forums, there's no resolution yet. It's just sad, knowing how powerful this tablet is. Even my mediatek Helio x10 or x20 phones don't experience lags. :/
[Shield Tablet Android Development] xanthrax:
Thanks for the the review, the slow downs you're experiencing and not only you it is related, most likely to the included bloatware. This tablet comes with lots of interconnected apps running in the background, there are heavy processes which can be stopped or frozen if you don't use them. That's why a custom rom runs smother.

Freeze all unwanted apps and you'll see the difference. Moreover, the system needs an update to nougat, let's hope that it will happen. The BitO kernel does a good job and makes a difference
