[Galaxy Note GT-N7000 Android Development] Zarhymn:
Extreme lag spikes on Lollipop Kernel, very high mmcqd and kswapd usage.

At random intervals, or when performing the very basic tasks of opening apps, browsing the web, lags and freezes were common, with app anr dialogs. Utilising the CPU Usage overlay finds that mmcqd and kswapd are the top 2 processes responsible for the lag in a lag spike. The usage spans from 65%-85%, resulting in a long wait before I can use the phone normally.

Now I went ahead to search up and found a similar issue affecting Nexus users running lollipop. This user managed to capture a full logcat of CPU usage and found the same 2 processes hogging the CPU. The kernel itself seems to be calling these processes. Memory stats are normal.

So maybe the kernel from lollipop has a huge issue, maybe try and simulate these results and find a solution? I'm using NightOwl's latest beta.

Using v8 with the latest SlimKat, how long does it take for the kernel to "settle"?

I do see an increase in speed but it doesn't seem to work much on rythm games (probably because it's more demanding?)

Anyhoo, after I used this kernel my backlight turns on even though the settings had it disabled. A clean flash doesn't work either
[Galaxy Note GT-N7000 Android Development] azlav:
will this v5 still support latest lollipop beta ?
[Galaxy Note GT-N7000 Android Development] forest1971:
It should work with beta9.
[Galaxy Note GT-N7000 Android Development] azlav:
well i saw the warning though in bouner's thread...i can't turn off my backlight button anymore, it keeps check and no change can be applied
[Galaxy Note GT-N7000 Android Development] forest1971:
It is so easy to flash a zip kernel. if you want to use custom kernel then u should try yourself. Don't live on others too much. If you try and have some problems then u can report, but better not report "other reports".

When I'm installing V7_T for KK Omni I am not able to access my external SD card. Strange.
[Galaxy Note GT-N7000 Android Development] azlav:
ahaha sorry, it's true that was my own report, i already used it before i made any comments...the backlit report part was based on my experience when i used raw kernel, i also unable to turn off the backlit, and to make sure i have no bad intention, i already post the report on both this thread and the rom's thread. :D
[Galaxy Note GT-N7000 Android Development] forest1971:
Okie. But this is not raw kernel thread?
[Galaxy Note GT-N7000 Android Development] forest1971:
No body seems to have this. Btw, better use v8 for KK which is the latest and better one.

Can someone help?
[Galaxy Note GT-N7000 Android Development] forest1971:
U can use odin version of Philz kernel for that purpose.
[Galaxy Note GT-N7000 Android Development] NLS:
Yes this is is what I was looking for too. But Philz only has very old versions in .tar.md5 format.

In any case I solved my problem, thanks anyway.

(I went back to original ROM and unrooted the device and then re-rooted and flashed 5.1 lolipop ROM)
[Galaxy Note GT-N7000 Android Development] :
So, is there a program to benchmark performance and battery saving for kernels? I wanna compare the usage, as I get a 10% drain when playing rythm games for about 10 minutes or so.

Edit: I use an xposed app called Performance Profile to underclock Clash of Clans and to maintain frequency for the rythm game to reduce lag.

But I'm also worried it clashes with CPU tuner, as both these apps have functions missing from each other. CPU tuner flexibly adjusts the speed according to phone conditions, but Performance Profile has more of an impact when you're opening specific apps.

Compatible w/ cm12.1 ?

Dear Forest, is the V5(CM12) compatible with LP ROM based on cm12.1, like Resurrection Remix 5.4.4?

If not, kindly consider updating your terrific kernel to 12.1 when you are less tied up. THX! :)

You disabled logging and debugging.

As a result a smoother, cooler and more battery-friendly kernel.

How to down clock this kernel I need 1.2ghz for better battery????
[Galaxy Note GT-N7000 Android Development] ASMI1:
go to about phone in settings and click 7 hits on the build info (this will show you performance and developer options in the settings

best CPU config (for me) are:

PEGASUSQ as governor

ROW as clock

i think you have to use 3rd party app to set cpu clock like No-frills CPU Control

here is the rom's link (thanks to [MENTION=1321017]porselinaheart[/MENTION])
[Galaxy Note GT-N7000 Android Development] nokiamodeln91:
I didn't say it is because of the kernel.. Or may be you quoted me by mistake or you didn't understand what I wrote.. After using cm11 with out rebooting for a long time, it tends to freeze and hot reboots..

I've been lurking around Omni and Dirty Unicorns for a good few months, but have recently switched to SOKP, so am interested in Forest's kernel.

It's great to see active development on the N7000.

Have fun :)
[Galaxy Note GT-N7000 Android Development] ASMI1:
the build of 04/11 is almost stable and Forest's kernel made it more stable and battery friendly (this is my own opinion)

Forest-M-Kernel_V1

NightOwl CM13 rom seems to be now stable so I make a kernel for myself and to give more options for Note users to play with. Feeling quite satisfied with this kernel:victory:

Forest-M-Kernel! another choice of MM kernel

Credit should go to [MENTION=799465]bauner[/MENTION] who has done the hard and excellent job with the NighOwl rom and kernel. I only make minor kernel tweaks.

Change log:

- Remove kernel debugs to reduce kernel load. Logcat is kept so that you can make log.

- OC CPU to 1600 Mhz in P (powerful) version.

- Play with different toolchains. V1 uses Uber toolchain. Will play with Hypertoolchain (to do)

- Play with GPU (to do)

- other minor tweaks

Instruction:

- Flash the kernel zip file in recovery

- Reboot, then use No-frills CPU control to set CPU frequency and desired governor/scheduler.

- Pegasusq/Row combo seems to be very good.

- Enjoy! :victory:

[Galaxy Note GT-N7000 Android Development] cuneyttekinay:
It is really good still developers support our old note. And thank you for your works.

Do you think to implement call recording to your kernel.

Oops. I forgot trim support. This is easy so will do it soon.
[Galaxy Note GT-N7000 Android Development] forest1971:
I believe call tecording is implemented in the rom level, not in the kernel.
[Galaxy Note GT-N7000 Android Development] forest1971:
Edit the above post:

I was wrong. after rechecking the issue found that trim is already enabled. the problem is with lagfix it does not seem work on NightOwl CM13.

Solution is easy and better: use Trimmer from Gplay store. It also offer schedule auto trim.

[Galaxy Note GT-N7000 Android Development] nokiamodeln91:
In nightowl 12.1 there was a cache file in init which activated trim once after a reboot and it used to get deleted. Is that not the case in mm?

Hi Forest, I have problems with the camera, I get the memory unmounted, kernel Forest M V1P

H60-L02 using Tapatalk
[Galaxy Note GT-N7000 Android Development] :
I hope this is not too much to ask, but how hard would reducing voltages for a bit be? I'm asking this since my Note on load heats up to about 75 degrees Celsius with 1400mhz on twitch, and starts to thermal throttle. How about even hanging the throttling temperature? I've seen this in a Note 3 kernel, changing the throttling temperatures manually in Kernel Adiutor, could this be done? Thanks in advance!
[Galaxy Note GT-N7000 Android Development] forest1971:
I put the throttle now at 71 degree C, 6 higher than stock. in JB kernel it can be increased safely to even 80 degree C. i feel keeping at 71 is suitable.

For voltage control i can open up voltage control interface in later version, then you can modified using Setcpu. For throttle, it should be kept at a safe level, and I do not know how to create interface to change it manually.
[Galaxy Note GT-N7000 Android Development] forest1971:
do you mean internal or external card? if internal, then should format it as vfat.

I do not have that problem with either. Suggest to try if it occur in stock NightOwl kernel or not.

Btw, camera in CM13 does not work well as the one in CM11 now.
[Galaxy Note GT-N7000 Android Development] panamera2011:
I solved after a new wipe cache wipe art the camera works.

doesnt meant to be greedy, but will you add an UV feature on this kernel? i think that would be great instead of OC as the problem (in my phone's opinion) is the battery life and the warmness. i dont know how your phone state is right now, but my phone still give me a heat. is it true that when you say "cooler" (like in the OP), it means only cooler than the stock but still hot, or it is really cool and no heat at all? sorry guys, noob need a food.
[Galaxy Note GT-N7000 Android Development] FabreFaction:
I have a cool experience with this kernel.

No excessive heat unless I'm thrashing a 3D game.

You might want to install Better Battery Stats to see if you have a rogue app chewing up your battery and your processor.
