Would you mind telling me how to set gpu freqency? I can only lower it with elementalX. Thanks very much :o
[Nexus 9 Original Android Development] Ishwara Sandesh C M:
It's awesome.. Super smooth..

But i m facing some hangs or hickups.. I don't know if i was the only one facing this issue.. Don't know if it's a rom issue or kernel's.

I am on saber aicp 5.1.1
[Nexus 9 Original Android Development] Ace42:
I use the elemental X kernel app by flar2. But Google removed his app from the store due to SELinux controls. Flar2 is working on a new app with a material design.

[Nexus 9 Original Android Development] omvir:
Just wondering, are the interactive governor values in your kernel the stock values that come with the stock 5.1/5.1.1 kernel? Or have you adjusted them ?
[Nexus 9 Original Android Development] USBhost:
No there still the same as the stock 5.0 kernel

But adjusted my me
[Nexus 9 Original Android Development] Phantom Pt. II:
I got the app but I can't use it since i didn't purchase it earlier. Don't want to go too far off topic, but would like to use this kernel with a working kernel app.

Trickster works just fine....
[Nexus 9 Original Android Development] wingdo:

Problem with Apps

Sorry I've searched and can't find an answer. Have it installed - ETX4 format, use trickster, wiped cache and davlik cache, using stock rom. Most everything is working fine but Dolphin browser force closes every time I try to load a site. Words with friends and Hanging with Friends won't load either. Any advice? Thanks in advance.
[Nexus 9 Original Android Development] BigJPNut:
Im on AICP with this kernel. I just installed 2 of the mentioned apps and both ran fine. Is your wifi connected?
[Nexus 9 Original Android Development] simonintx:
-Yep wifi is connected. Getting emails, browsing facebook etc etc. I deleted and re-installed the apps, same problem.
[Nexus 9 Original Android Development] USBhost:
Can you get a logcat of the fc

Thanks
[Nexus 9 Original Android Development] BigJPNut:
I havent been on stock in months so its hard for me to chime in. Hopefully usbhost comes thru with an idea

[Nexus 9 Original Android Development] ousoonerchase:
Just curious, you said this is sabermod based. Which build did you base this release off of becuase the latest 4/29 build is corrupted and if possible I'd like to match your development target. Also, the earlier 4/29 builds have bluetooth errors. Cheers :good:
[Nexus 9 Original Android Development] USBhost:
bluetooth errors? my Bluetooth is fine...

And the 4/29 build is corrupted? Try to download it

from another browser

My kernel is not sabermod based

it's only built with sabermod..
[Nexus 9 Original Android Development] ousoonerchase:
The 4/29-2007 sabermod build is only 147.32mb where 4/29-1644 is 311.03mb. Just wondering what build of rom you're running without the errors. Thanks
[Nexus 9 Original Android Development] USBhost:
Its an old one April 22

I don't update ROMs when I'm kernel testing

because I don't want to blame the bugs on my kernel
[Nexus 9 Original Android Development] 12paq:
AICP SaberMod 4-29 2007 is an incomplete rom file. It actually crashes TWRP when flashed. Use one of the other 4-29 builds. And report it in the correct AICP thread or the moderators will scold you. ;)

Other people have this problem with CM12 and fire-ice?

When I connect the tablet to the computer MTP does not work, it only works in the recovery, the problem has to start with the a few latest updates. I also have the fire-ice kernel, I think is come from the kernel but i am not sure.
[Nexus 9 Original Android Development] USBhost:
MTP is working awesome on Ubuntu
[Nexus 9 Original Android Development] Max128:
My windows is work perfectly is a problem with the rom or the kernel i will test it soon.

[Nexus 9 Original Android Development] Max128:
No the model wifi and is working before with cm12.
[Nexus 9 Original Android Development] Megaflop666:
Your k9 beta build is running great on the latest cm12. Been loving your kernel on my n9 for a while now. Thanks for all the hard work.
[Nexus 9 Original Android Development] 12paq:
Just curious, what's K9.1.r2.zip?
[Nexus 9 Original Android Development] USBhost:
Some more changes

From the last one
[Nexus 9 Original Android Development] Ripx88:
First I just wanna say I really appreciate all the hard work going into this kernel. It runs great, has been my go to for quite a while now. I had a quick question though, hopefully someone can shed some light. I enabled OC on the GPU using terminal.

Anyone know of a good app to control frequency's on the CPU and GPU. I use No Frillz CPU. Works good there's just not GPU option. Not that I necessarily need to over clock my GPU, K1 is a beast graphically. I just like to tinker :D
[Nexus 9 Original Android Development] USBhost:
I can make a tasker app

For that if you want

Also note GPU oc is default
[Nexus 9 Original Android Development] USBhost:
Man those two people

You guys are just like me lol

I take my hat off to you guys :cowboy:

BTY how do you know when I upload them?

Also how's k9.1.r3

Working for you guys?
[Nexus 9 Original Android Development] Ripx88:
That's totally up to you bro. I don't know how much work it involves. If its something you don't mind doing and is not going to take a lot of your time then sure that would be awesome :)

Theres a r3 now? Your quick lol. I'll have to update. I'm having issues with AICP. Just not running good at all. Will flash a different ROM tomorrow and grab the most recent K9. This is definitely the go to kernel for the N9.
[Nexus 9 Original Android Development] USBhost:
You can thank CM for AICP bugs lol

r3 its in the beta folder

I will work on the app

tomorrow
[Nexus 9 Original Android Development] Ripx88:
Yes CM is definitely the culprit. Always is! I really appreciate you doing that :D

Also I notice even when I overclock the CPU to 2.5 ghz it doesn't ever go past the 2295. Just under 2.3 ghz. Have you noticed that at all? Also checked the CPU usage in No Frillz and the processor is definitely not going above 2.3
[Nexus 9 Original Android Development] USBhost:
Try trickster mod
[Nexus 9 Original Android Development] wingdo:
Until Aaron releases a replacement for the ElementalX Kernel App, Trickster is the way to go.

8.11 has been so steady for me I am waiting for either a final of 9.1 or perhaps 9.2 before I upgrade. Your kernel is rock solid.
[Nexus 9 Original Android Development] Ripx88:
Still doesn't go above 2.3 even with trickster. Not a big deal. Just weird how its not working when others do it all the time.
[Nexus 9 Original Android Development] USBhost:
K9.1 is out

K9.1

-| Latest from google's Tegra branch

-| Linux 3.10.77

-| LMK fine tuning

-| Bugfix: resume freezes

-| Bugfix: ZRAM not properly being used

-| ramdisk: some fixes and additions

-| interactive gov fix big adjustnents

-| FI.d addition

Notes:

Say good bye to all those reloading tabs

in chrome.

LowMemoryKiller

The default LMK values where so aggressive

that swap didnt really have a chance to work.

so i made the LMK a lot less aggressive.

LMK will no longer kill processes until

swap is full.

SWAP/ZRAM

/proc/sys/vm/swappiness was 0 its now 60.

zram was lowered from 500 to 380 mb

because of my changes to LMK.

you can make it larger if you want to..

FI.d

this is my new init.d folder

that will only execute until everything

in init.d goes first then wait one minute

then everything in FI.d will execute.

FI.d folder is now where my bootup scripts will be.

if you what to know more and or my reason for it

look in /system/etc/FI.d/00start

[Nexus 9 Original Android Development] wingdo:

[Nexus 9 Original Android Development] tyvar1:
Aweosme update! Thank you :D

Also. 5.1.1 release today! :D
[Nexus 9 Original Android Development] Steffe89:
The K9.1 is running really great! I'm getting 4-5 h of battery usage after mainly using Chrome beta. (ACIP from 7th may) And most importantly, it's very smooth and apps are not closing randomly now!

I do, however, see the device freezing completely approximately once per full battery usage. The dispay turns white or shows weird colours and i have to hard reboot. I'm wondering what this could be? It may happen in every and is more or less random.

You need to elaborate this. My chrometab still keep reloading when switching between the tabs, and also if i close and open chrome (after some time though).

Finally, the 5.1 is released. Is there anything you can use from that to make this kernal better?
[Nexus 9 Original Android Development] USBhost:
Hmm will look into that

5.1 kernel source is not out yet

Note about chrome

each tab uses about ~50-100 mb

of course you'll get reloading if you go over 10

And or you wipe it from recents.

One time I got to 197mb for one tab
[Nexus 9 Original Android Development] Steffe89:
Is there any way to get the log from the freezing incident?

It's actually happening with 2-3 tabs. I never go above that for obvious reason. I can easily make the tabs reloading if i have androidpolice.com in tab1 and eb.dk in tab2. I also use adblocker, so that should also lower memory usage per tab.
[Nexus 9 Original Android Development] USBhost:
can you do

dmesg

in terminal

about the log of the freeze

look in /sys/fs/pstore/
[Nexus 9 Original Android Development] Steffe89:
Sure :). dmesg attach and the one logfile i had from pstore is zipped (too large)
[Nexus 9 Original Android Development] USBhost:
ok that explains it

working on a fix
[Nexus 9 Original Android Development] Steffe89:
Thanks! The freezing incident or chrome reloading?
[Nexus 9 Original Android Development] USBhost:
chrome reloading

Can you do this in the mean time

Reboot unlock the screen

Wait 1min

Then try to make chrom reload

And if you get a freeze

Force reboot then give me the log in pstore

If what I said fixed your chrome reloading

I will tell you what happend
[Nexus 9 Original Android Development] Steffe89:
1st reboot: Error "omniswitch has stopped" before i could start decrypting/starting the tablet.

2nd reboot: All ok. I'm having a hard time making chrome reload the tabs(still two). I tried to start Facebook, Messenger, Pushover, Skype, which i also use and then one of the tabs had to reload. Am I already low on memory?

No freezing... yet...
[Nexus 9 Original Android Development] USBhost:
ok try this one

zram is now 400mb

also if you get a reload

in terminal do

free

give me the out put
[Nexus 9 Original Android Development] enriquejones666:
Yes, I noticed this too, even when using TricksterMod to set max CPU freq. (I'm using K9.1)

Just add the following line to /system/etc/FI.d/01afterboot

echo 2499000 > /sys/module/cpu_tegra/parameters/cpu_user_cap

(You need to reboot for the setting to take effect)

Compiling Error

[Nexus 9 Original Android Development] Steffe89:
Increasing the zram improved reloading of chrome tabs.

Had another crash after 2mins of playing minecraft. I have attached the log here. Can you see anything?

Edit. Had another whitescreen freezing. Another log added.
[Nexus 9 Original Android Development] USBhost:
Yes that's a bug with it

I can give you my toolchain

it has the workaround for that problem
[Nexus 9 Original Android Development] USBhost:
Good news found the problem

The system freezes when free ram goes lower than 61mb

so I need to a just LMK a bit
[Nexus 9 Original Android Development] Beta1440:
Yes, I would appreciate that. Also, if I want to install the kernel, do I need to use your ramdisk, or can I use another?
[Nexus 9 Original Android Development] USBhost:
You can use another
[Nexus 9 Original Android Development] Steffe89:
Already had two more system freezes since I posted to logs.

Great you found the issue! Could you tell that from the logs?

The device really seems to have too little memory :/

I was wondering if this also explains why I don't get notifications from Skype/Pushover etc. I have to open those app and then updates are pulled. FB messenger works fine though. Perhaps a rom problem?
[Nexus 9 Original Android Development] USBhost:
Well yes and no

the first one didn't really help me out

2nd one did though.. helped me reproducing it

I know I would have been awesome if we had 2.1gb completely

not 1.8gb also if system did not use 600mb+

Dont know about that

try out 9.1.2.r3
[Nexus 9 Original Android Development] cr0wnest:

K9 is very smooth and stable. No complaints here. But I shall try out 9.1.2r3 though. My OCD will never let me use anything dated. :D
[Nexus 9 Original Android Development] AllanJacques:
So, any thoughts on 9.1.2r3?
[Nexus 9 Original Android Development] cr0wnest:
I only just installed it today, so it'll be another week or so before I can give my judgement. Using it with the 8 May build of the AICP SaberMod ROM and so far it seems just as smooth as K9 if not better.
[Nexus 9 Original Android Development] nericollin:
I can confirm the same here as well. Using the exact same setup
[Nexus 9 Original Android Development] AllanJacques:
So, no good...

9.1.2r3 is still laggy and hangs a lot...
[Nexus 9 Original Android Development] USBhost:
true

LMK is not working with me...

Edit: im making cache

do some work
[Nexus 9 Original Android Development] Ace42:
2GB RAM + 64bit os is a terrible combination (with iOS being an exception). I think the best way to overcome this would be for Google to reduce RAM usage of system files/drivers or...create a 32bit version of 5.x for N9. 64bit always has a greater memory footprint, which is why at least 3-4GB is needed.

i decided to make cache work for

memory now. fixed up the LMK :: still WIP

but now it will kill but not as much as stock!

this was done to stop all the lag when ram went too low.

A beta of the replacement for the ElementalX kernel app is up on Google Play.

Not sure if you need to join the G+ community before you can become a tester (probably do), but it works well with Fire - Ice and you can control the GPU clock as well.

Cool! Will flash this.

I noticed the default I/O Scheduler (SIO) is pretty laggy, it was like this on K9 as well. Stuttering inbetween UI presses and animations for no reason. Changing it to NOOP seems to solve this, though i'm testing it with FIOPS now and see how it goes.

I flashed from your kernel to the new ElementalX last night and neglected to do this step:

Every time that I reopen Chrome it asks me to sign in as if it was the first time I was using the app. I've also had to sign back into XDA through Tapatalk on a couple of occasions too. Any idea if this might be caused by not reformatting to ext4?

Thanks!
