Testing 8.5 now...

It still seems that 8.3 was smoother...

Could it be because of the governor? I mean, I noticed that there is no more elementalx to choose...
[Nexus 9 Original Android Development] USBhost:
O right

I forgot to mention

on 8.3 elementalx did not like 3.10.73 :: merge conflict :: I did a dirty fix

So On 8.5 I reapplied Linux but left elementalx out until

I properly fix it
[Nexus 9 Original Android Development] ExLucif3r:
Hi,

Stock and ElementalX didn't have this issue..
[Nexus 9 Original Android Development] USBhost:
thanks

I have something to work

i think in k8.6

i will make it stable

The CPU frequency.

One thing in my to do list

Make it 3ghz
[Nexus 9 Original Android Development] Ace42:
Didn't you overclock it in that benchmark??

Where is my 8.6?
[Nexus 9 Original Android Development] USBhost:
I declare you OKUD

It's coming

properly today :cowboy:

Just making sure

everything is good

I plan on making it a stable release
[Nexus 9 Original Android Development] dictionary:
No matter what ROM I run, nothing past 8.3 will boot for me. Still related to encryption? Why is 8.3 good and no others? ;(
[Nexus 9 Original Android Development] USBhost:
ok...

What do you mean in not booting

boot loop/rebooting

or other

Also Im encrypted at the moment

so it's not encryption
[Nexus 9 Original Android Development] dictionary:
Same as I was saying before. Just bootloops. Let it so it for 20 minutes, bootlooping. Shut off then flash 8.3, boots no problem. Really no clue. Gonna try to get access to a PC to grab a kmsg. Probably something dumb on my part.

****Edit: As if to prove me a liar, grabbed a computer, flashed, get into my cmd prompt ... and it boots. Smh. CM12.1
[Nexus 9 Original Android Development] USBhost:
K8.6 is up

fate man.. fate!

---------------------------------------------------------

K8.6

-| elementalx gov is back

-| optimize unaligned memcpy and copy_* :: this thing works!

-| toolchain update

-| small changes to the defconfig

if everything is good

going to make it stable
[Nexus 9 Original Android Development] dictionary:
8.6 boots lovely might I add lol. I was the second person to download again. Credits to that number 1 person lol.

Was so glad to see elemental back!!
[Nexus 9 Original Android Development] USBhost:
cheers to him

and to you

:cowboy:
[Nexus 9 Original Android Development] BigJPNut:
Awesome....ty!
[Nexus 9 Original Android Development] AllanJacques:
What is OKUD?

Anyway, thanks!

BTW thanks for elementalx governos back and a quetion, shouldn't you put other traffic congestion mechanisms before calling it stable?

And another question comes to my mind, in default settings zRam is enabled but swappiness set to 0, why is that? Wouldn't be better to disable it?
[Nexus 9 Original Android Development] vogemic:
For some reason I lose mobile connectivity with version 8. I'm on CM 12.1 and had no problems with the stock kernel. Only reboot fixes the problem (temporarily). Anybody else with a LTE-version experiencing this?
[Nexus 9 Original Android Development] USBhost:
obsessive kernel updating disorder

Others? I already enabled all

All tcp congestion mechanisms

About the ZRAM

don't know why it goes to 0

yeah maybe I should just disable it

with option to enable it
[Nexus 9 Original Android Development] AllanJacques:
Yep! OKUD!

Anyway, tcp congestion only shows cubic and westwood for me!

BTW what is the best tcp mechanism?
[Nexus 9 Original Android Development] USBhost:
Oop your right...

I must have missed them lol

New build will be up today
[Nexus 9 Original Android Development] R3Lax1:
Will 8.6 be compatible with the (upcoming) cm12.1 official nightlies?
[Nexus 9 Original Android Development] USBhost:

[Nexus 9 Original Android Development] R3Lax1:
Thanks for the lightning quick response :)
[Nexus 9 Original Android Development] BigJPNut:
I only show reno and westwood....
[Nexus 9 Original Android Development] AllanJacques:
Well I got to be honest with you, 8.3 is still the best in terms of smoothness and performance for me...
[Nexus 9 Original Android Development] USBhost:
Hmm...

And here I got the best benchmark

on 8.6
[Nexus 9 Original Android Development] bbedward:
You will learn this means nothing once you run the BFS build ;)
[Nexus 9 Original Android Development] USBhost:
Your so right
[Nexus 9 Original Android Development] hoof hearted:
Saw k8.7 for 5.1 on you site. Tried it out for a few hours. Very very smooth but had some random reboots . noticed the bfs RR interval. Is this something we will get to tinker with in the future? After the reboots, went back to k8.6. So far so good.

And now I see k8.7 is no longer available. So now I'll wait. :fingers-crossed:
[Nexus 9 Original Android Development] USBhost:
Bfs causes rebooting on sleep

so that needs fixing
[Nexus 9 Original Android Development] hoof hearted:
Makes sense. Excited to see what you can do with it.
[Nexus 9 Original Android Development] lasset:
What more can you ask for? Thanks!
[Nexus 9 Original Android Development] omvir:
I use [MENTION=2632235]bbedward[/MENTION] s zen kernel on the nexus 6. And it's so damn smooth! Can't wait for it to be implemented in this kernel for the nexus 9! Hopefully all the issues around the reboots can be resolved!
[Nexus 9 Original Android Development] AllanJacques:
I don't even benchmark, my overall user experience is way better with 8.3...

[Nexus 9 Original Android Development] bbedward:
I just need a good trace of the suspend issue and I will fix it :)
[Nexus 9 Original Android Development] AllanJacques:
Are you working on this kernel too? If so, congratulations and thanks a lot!
[Nexus 9 Original Android Development] bbedward:
Not quite, but I brought my BFS port from the N6 over to the N9 and added support for the silly nvidia stuff.
[Nexus 9 Original Android Development] AllanJacques:
Dude, please make it happen?

Pretty please?
[Nexus 9 Original Android Development] bbedward:
It is :p there's a panic bfs causes when suspending, probably an easy fix but I need somebody to give me a good stacktrace because I don't have an N9 :p
[Nexus 9 Original Android Development] bbedward:
Usbhosts kernel disables all debugging so the only trace I have isn't readable :angel:

My kernel build has an f2fs bug so nobody can use it :p

http://xdaforums.com/showpost.php?p=60204232&postcount=55
[Nexus 9 Original Android Development] bbedward:
This at least tells me it's related to the nvidia support stuff I added (cpuquiet)

Workqueue: cpuquiet 0xffffffc000987078
task: ffffffc06672f000 ti: ffffffc0667d0000 task.ti: ffffffc0667d0000
pc : [<ffffffc0000df308>] lr : [<ffffffc000980fac>]

But the PC and LR registers are just displaying raw memory addresses (rather than the method names as they often do)

Perhaps you can build with stock defconfig and make sure SCHED_DEBUG, ARM_UNWIND, SLUB_DEBUG are enabled?

Maybe you can find the addresses like ffffffc06672f000 in the generated System.map after the build? If not then enabling those other debugging is probably the way to go.
[Nexus 9 Original Android Development] USBhost:
Will do

Edit: will do in a few

about 1h
[Nexus 9 Original Android Development] bbedward:
Edited. You can see if you can find them in System.map first
[Nexus 9 Original Android Development] USBhost:
OK now this should help

Anything need to be done for the "link" in terminal or is it just part of the kernel now

Well yes and no

You just put

BL then the number you want in terminal

BL is just a simpile script that was put in /system/bin

echo "$@" | su -c tee /sys/class/backlight/tegra-dsi-backlight.0/brightness

In the kernel i changed backlight

you need to copy it to clipboard

no it wont stay over reboot

USBhost can your N9 get these I/O scores in androbench? (279 read, 79 write)

I think the 16GB uses a slower nand chip...I can only get ~120mb read after disabling encryption.

" LTE support "

Does this mean it removes the fact that "Mobile networks" is using my battery and keeping the tablet awake while it's not being used. I've got the LTE model but I don't have a SIM card in it.
[Nexus 9 Original Android Development] USBhost:
Can you do

dmesg in terminal

when it does not sleep
[Nexus 9 Original Android Development] Phantom Pt. II:
You mean the Terminal emulator app? When I simply type "dmesg" in there it tells me

klogctl: Permission denied.

I haven't flashed your kernel, btw.
[Nexus 9 Original Android Development] USBhost:
I can do a special build with no lite

When you guys get a reboot pls give me the log

OH. Forgot to turn that off. I will try that while running the beta version. Thanks.

I'm not entirely sure that chrome is the issue though. Might be the installation or something.
