[KERNEL] [SM-N9005 HLTE] [03 July] SkyHigh TW Kernel [v3.3]

THIS PROJECT IS NOW ABANDONED DUE TO MY OTHER COMMITMENTS FOR FAMILY, WORK & OTHER DEVICES IN XDA. THERE IS JUST NOT ENOUGH TIME IN THE DAY. SEE YOU ALL AROUND XDA & HAPPY MODDING !!

N9005 HLTE TW supported only. (No S5 ROM port. Newer ROMs based on NFx firmware may not be compatible )
I don't have time to build and debug for other variant devices I can't test or a ROM I don't use - sorry.

Let get it straight, I am not a real Developer, but I am UpInTheAir, former part time kernel “hack” of SGT 7.7 JB & ICS Kernels. I now share with you my first SELinux TW N9005 LTE Kernel compiled from official Samsung sources.

* I don't pretend to know everything, so if you can be constructive and help out this project, please do so. You will find allot of answers by searching gitHub, XDA and SEARCH

Just like I do …......

v1.0 is released. Please read Posts #1-3 before flashing.

I'll post initial changelog somewhere in due course, but time to get working on v1.1

Reminds me, I'll post a disclaimer...........

Edit: I'll upload a flashable stock boot.img

finally after your awesome kernel back then in 7.7...congrat and tq for this kernel

Your welcome. :good:

Big thanks to the real devs here and hard-working forum members that also contribute to the various features and commits etc !

More to come of this simple kernel yet

But don't expect it to be full works. I can only do my best with my limited knowledge and the time I can afford. I just see it as a challenge and share accordingly. Also big thanks to @civato with many of his initial commits and base synapse config.

Cheers,

UITA

Screenshots

Added some screenshots :good:

Doesn't cover all options, but users should get the idea

Next release, user will be able to set CPU voltage for individual frequency (as in screenshot). I've kept the Global CPU voltage control in case user prefer that.

Baby steps...........

GPU oc doesnt work properly

If you're going to post in development section with a percieved "bug", please in future give full details allowing to replicate.

Reflashed v1.0 & tested with Antutu GPU test. GPU OC - works fine. It scales to 550 MHz if load requires. If you want to lock the frequency, set the min to the same as max.

Edit: I use cool tool app to observe "live" frequencies during testing etc

Edit 2: I believe (could be wrong. Need time to study code) that the GPU may have thermal limiting, reducing frequency under high temp, just like the CPU. This would also be normal.

Seems to be a lot more stable for synapse boot (under SkyHigh default conditions).

Enjoy :good:

Update to v1.2 sometime today or tonight. I'm really busy, so no time for release. .....

I just checked and all is good.

I like to keep this project in one place. Great idea by XDA.

Please try again, sometimes the XDA is a little "finicky" to UL, so maybe same for DL too. Refresh your page and try again :good:

I have to go away for a few days, I have plenty of ideas and additions for next release. Until return......

Hey buddy. Gr8 Job mate..
I have V1.3 on my device since dis mornin, and I can say it's gr8....!!!! Thx
I just need some info about the settings in wifi & Advanced section in Synapse. It would be so cool If u could explain more about diz parts.... :good:

Thanks. The kernel is still a "work in progress", and trying to keep it stable but with a number of mods and exposed configurable options.

I'm still not sure if I'll add any custom governors or schedulers, easy to do but the stability of stock is great. Maybe intellidemand though?

I'm away for a few days, so I will try and add some info into post 3 and synapse as I progress with further builds when I return home.

Wifi - use cubic or Westwood plus. Edit: Maybe I'll look at adding option to use Google dns server, tcp speed tweaks etc from V6SuperCharger.

Personally, I haven't yet had to tweak the LMK minfree values on Note 3 (unlike my Galaxy Tab 7.7 with 1GB RAM and multi-window mod). It's just got so much RAM and great multi-tasker. I haven't got around to playing with entropy values either. A lot of tunable values are just exposed so if user "wants" or "needs" to tweak, it's there anyway.

There is a lot of info on the Internet that can explain things better than I ever will or pretend to understand. In that case 99/100 times I leave the values at stock.

My personal value for randomize VA space =0. Supposedly helps with GUI smoothness. ..... Somethings are hard to tell or placebo.

I've got lots of things on the "to do list", Enjoy v1.3 and beyond
