This and some other descriptions in OP like "smoother, cooler and more battery friendly" makes me wonder how this was achieved and why the original developer team didn't do this.

In OP there is written:

"2.Disable all kernel debug and logging

3.Some minor optimizations of config file"

and with v2: "more tweaks to the config file to further reduce heating"

So with some changes in the standard config file it gets faster, battery "considerate" and cooler. And a normal user can feel or measure it.

Significant changes are a result from significant optimizations in the kernel sources - at least this is my experience.

I simply assume that an experienced and brilliant developer team like CM doesn't release a config file with really bad values after modifying the kernel.

Maybe the OP can shed light on this and explain his optimizations with a few examples.

Hi [MENTION=4576973]forest1971[/MENTION]

Do you have the MD5 checksum for the V2 Kernel please......... not that I don't trust MediaFire..................
[Galaxy Note GT-N7000 Android Development] forest1971:
No. a bit lazy doing that since seeing no problem so far. if the kernel flash fine and works well then no need to worry about md5. maybe I will generate md5 later on. cheers.
[Galaxy Note GT-N7000 Android Development] forest1971:
The changes aim to eliminate logging and debugging actions by kernel to reduce cpu and ram workload. Hence, it helps reduce heating.

The stock version need to keep logging and debugging to be complete, but most users do not use these functions. They can flash back to stock to get log.

About CM they are legendary and i have no doubt about it.

btw, you have recently sound like a difficult old man mate :laugh:!

V6t kernel (slim) trimming not works with lagfree app ( kernel not supported message)
[Galaxy Note GT-N7000 Android Development] azlav:
wait wait wait...what happened?are there any side effects?:eek:

you can use terminal emulator and type the commands yourself

fstrim -v /system (for system)..change to other partition such as /data, /cache and if something changes, include /preload
[Galaxy Note GT-N7000 Android Development] carabao72:
Hello,

A small question, I suppose that the fstrim command has to be made unsettled partition ?

Possible via the application terminal to emulator? No, I suppose!

Thank you
[Galaxy Note GT-N7000 Android Development] Lanchon:
fstrim -v /the/mounted/partition

must reply: XXX bytes trimmed

otherwise it is not trimming!

[Galaxy Note GT-N7000 Android Development] forest1971:
It will introduce a bug when booting or charging off line. The bug is mild in tw but a bit more troubsome in cm. Btw, with trim the performance is already amazing for kk so decided to drop oc oled to avoid the bug.

Hi [MENTION=4576973]forest1971[/MENTION],

This is the first time I've ventured into the Trim world / (kernels), so please bare with me... lol

Whilst I understand that all bricking of eMMC is practically non-existent now as it was only (ICS stock kernels that were affected, and all GB, JB, KK & LP are fine).

This is new to me, so basically just going by what I see... I've installed the KK kernel, so guess Trim is included/built in. But I believe you have to run it first via the App. I've got the App installed, but do I select all partitions (as included in this quoted message) even System... Or will that cause issues...??

Thanks, Lister

do the bug exist even from 59Hz OC?:crying:
[Galaxy Note GT-N7000 Android Development] GeeckoDev:
I think building the entire kernel with -fno-pic solves the issue. If I remove this flag with the TW kernel, the recovery becomes inaccessible (that's why r4/TW is currently broken).

I also observed that even with this flag, the screen can flash sometimes but it's very rare. A reboot usually solves the problem.
[Galaxy Note GT-N7000 Android Development] forest1971:
Great finding Geecko! as always you lead the way for our device kernel development with magic after magic!:good::good::good::good::good::highfive:
[Galaxy Note GT-N7000 Android Development] GeeckoDev:
I never tested it on AOSP and I don't know the exact effects of -fno-pic (it's always used when building kernel modules in Android, but not for the whole kernel. but SpeedMod does this). Also maybe the lcdfreq driver in /driver/video/samsung/lcdfreq.c is part of the problem.

Thanks :)

Dear Forest,

I am on RR528 and was on 527.

I had no issues with v3t. The phone only has probs with dowbloading large files, to slow and sometimes phone gets hot. But I dont think that is kernel side.

On 528 for 1h everything ok.

I had to delete data of lagfix premium though. They removed superuser for some weird reason and lagfix didnt survive that. After deleting data privacy guard granted root and lagfix went successfilly through the process. Of course I cannot tell what it really does at all ;) Btw, I had to use Nexus4 buildprop data to force google play to show lagfix at all! Just in case any of you are wondering.

I had GPS after 10sek after flash and boot.

No Wifi problems on my side.

I noticed RR528 says it has CWM 605 and v3t only has 6049. may that be a reason to problems u said existed?

In case you care: I dont understand why OLED OC was decided to be not implemented. Could you please explain in other words? Thank you.
[Galaxy Note GT-N7000 Android Development] Lanchon:
found this:

" Another issue is that the kernel does not export the _GLOBAL_OFFSET_TABLE_ symbol, so modules need to be compiled with the -fno-pic compiler option. I'm not sure why that actually works, but it does. :) "
[Galaxy Note GT-N7000 Android Development] phoenX80:
RR528+v3t

I charged phone over night switched on. Phone was cool and charged 99%. The 99% may be a bug, I had this on 526 and 7 also. Maybe 5h charging is not enough.

Weird, I found this morning I left it at 500-1200 this night by accident and phone hasnt crashed until now 9h later. So this experience may have been caused by something else
[Galaxy Note GT-N7000 Android Development] avincric:
read OP carefully.

v3t is NOT recommended for rr 5.2.7...therefore it obviously ges for 5.2.8 as well.

if you're still persistent to use it,dont expect it to work without bugs

That is the exact reason im giving forest the feedback. I think hes not even sure wether its suitable or not. So im telling him basically theres no issues on my phone.

What is the TRIM? Why does it make phone faster and is it really faster than without it? Is it dangerous for bricking phone? Thx for answer. :)
[Galaxy Note GT-N7000 Android Development] azlav:
yes, usually battery draining is caused by wakelocks,check if any of it exist using wakelock detector, while discharging of course...then report it and make sure u turn off all auto sync as the first step..

just flash it and wipe dalvik & cache the reboot...asume you are in the right rom

simply, it delete unused blocks...it should be fine if your phone doesn't have trim bug...just ask Lanchon if you really blind about it

V6 and V7 performance on KK

[MENTION=1301150]ashes[/MENTION]

In response to your query about the performance of this kernel on KK ROMs, below is my experience.

I have used both V6 and V7 with Dirty Unicorns KK ROM which is Omni based.

I have been using Dirty Unicorns for over 12 months now, occasionally trying other ROMs, but always returning to DU.

My current setup is at the bottom of this post.

I haven't tried the Lollipop ROMs yet as some of the glitches would affect how I use my device, HD Video recording for example.

Both V6 and V7 perform well.

Both V6 and V7 seem equally quick, even with V7 throttled back to 1.4GHz.

V7 is definitely smoother than V6, probably as a result of the increased refresh rate.

Both kernels are noticeably faster and smoother than the "stock" kernel in the DU ROM.

3D performance of both kernels is much better than the "stock" kernel in the DU ROM.

Far less tearing and jitter in 3D apps, with V7 performing better than V6.

V7 battery performance is better than V6.

Battery performance in V7 is better than the "stock" kernel in the DU ROM.

Battery performance in V6 is worse than the "stock" kernel in the DU ROM.

Also, the occasional freezes, reboots, force closes etc. I was getting with the stock kernel seem to go away with V6 and V7 on Dirty Unicorns.

I am sticking with V7 for the moment.

I like the silky smoothness of transitions and scrolling.

There is still a little jitter on scrolling in some apps, but much less than with other kernels.

In fact the jitter is hardly noticeable.

Thanks [MENTION=4576973]forest1971[/MENTION] for continuing to improve our device.

It's great to see talented individuals such as yourself continuing to push the boundaries with Kernels and Lollipop ROMs.

Current Setup:

ROM: KitKat 4.4.4 Team D.I.R.T Dirty Unicorns V8.2 20141104-1817 UNOFFICIAL TEST BUILD

KERNEL: Forest KK V7 T(Omni)

GAPPS OFFICIAL Up-to-Date PA-GOOGLE APPS + gapps-config.txt

Radio: N7000XXLT3

Partitioning: 8Gb DATA Application Partition with PreLoad
[Galaxy Note GT-N7000 Android Development] ashes:
Thanks a lot for the detailed explanation.

I'm currently trying CM12 but in the past I've been using DU also. From all the KK roms for me it was the best one - still having some random reboot from time to time.

I'm happy with CM12 for now, but i agree that Video Recording is important. I'll keep with it while waiting for the fix from [MENTION=799465]bauner[/MENTION] - but if I've to go back, DU will be the option.

The fact that DU was discontinued was also why i decided to try CM12.

Nighowl CM12 stable release with Forest kernel (with bugfixes and OC oled) will be the best option, in my opinion.

Kudos for everyone working on the old note :highfive:

[Galaxy Note GT-N7000 Android Development] FabreFaction:
With both V6 and V7 I don't seem to get any of the random reboots, freezes, FCs I got with the stock kernel on the DU8.2TestBuild.

I will update my original post to reflect that.

It is possible we might see an Unofficial DU Lollipop build at some point in the future, but no guarantees.

NightOwl seems pretty close to what I would consider to be a daily driver, and [MENTION=4576973]forest1971[/MENTION] kernels have improved every ROM I have used them with, so looking forward to that setup in the near future on my device.

---------- Post added at 02:09 PM ---------- Previous post was at 02:03 PM ----------

To be honest, I didn't know there was an LT4 modem out.

I use this thread to source my modems, and LT3 is the latest on there.

Where did you source LT4?

UPDATE:

Looks like LT4 is the ROM not the Modem.

The LT4 ROM came with a variety of different modems depending on region.

Source - take a look at post 497 onwards.
