[Kernel][N8000 Beta][OC][TW][Linaro][23 Dec]Xcstacy Kernel Linaro v2.0

xcstacy · Apr 12, 2013

Hi all,

I am quite new to this forum and I haven't found a decent kernel in this forum so I've decided to make one myself for daily use.
I am not a professional coder but I do know the basics of Github and all other necessary things to make this kernel work.

Please look here for current build.

This is a kernel for N8000/N8010/N8013. ~~I might add support to N8013 variant if the kernel is overall stable.~~

I will try my best to bring patches from great kernel devs e.g. Faux, Gokhanmoral, Franco and many more to our Note 10.1.

This kernel is working on latest OMEGA, Redemption and ARHD ROM.

Initd is finally fixed.

This kernel is currently compiled with Linaro Toolchain(cfx toolchain) 4.7.3 from codefirex.

To enable cifs, type these in terminal
su
insmod lib/modules/cifs.ko

Disclaimer:
Not responsible for bricking your phone, voiding your warranty, or any other pain or suffering you may feel as result of using this kernel!!!

Installation Guide:

Note: First of all BACKUP your current kernel! See the backup section of this post,

A. Using Recovery:
1. Reboot into recovery.
2. Flash the zip file of the kernel.
3. Clear Dalvik Cache to be sure (Not obligatory, but recommended).
4. Reboot.

B. Using Mobile Odin:
1. Extract boot.img from the zip file of the kernel.
2. In MobileOdin under kernel section select the boot.img file.
3. Hit 'flash firmware'.

NOTE: If you flash any ROM, the boot.img of that ROM will be flashed. So if you flash Stock ROM or restore your Stock Backup your kernel will be STOCK. If you want to use this kernel you have to flash again after doing those things.

Reverting back:
A. If you have boot.img and Mobile Odin:
1. Fire up MobileOdin and under kernel section, select the backedUp boot.img of yours.
2. Hit 'flash firmware'.

B. Using TWRP recovery:
1. Restore the backup you performed before you flash this kernel.

C. If you don't have any of those backups:
1. You can always try the boot.img which is in the ROM zip of the custom ROM you're using. If you're stock and you don't have the ROM zip you can ask in the Q&A thread for the users to upload the one for you. Just mention the base of your Stock rom (ex. CMD1) and they would help you. After you obtained boot.img you may use A of this guide to flash it using mobileOdin.

Backing up your Currect Kernel:
A. If you have ROM zip of the custom ROM you're using:
For example you're using ARHD 7.0:
1. Open ARHD 7.0 zip file (The rom zip file you flashed in order to install ARHD 7.0) and extract boot.img.
2. This would be the boot.img of your current rom. So keep it safe in case you wanted to revert.

B. If you don't have ROM zip or you're stock:
You will need TWRP recovery to perform this.
1. Reboot into recovery.
2. Select backup.
3. Only Check boot.
4. Perfrom backup.
5. Keep the backup files safe.

Known Issues:
Some people are experiencing hard reboots with build 5. Use build 4, Xcstacy is working hard to fix the issue.

Useful Programs:
- MobileOdin: To flash firmwares, kernels, and other stuff. Very useful app for samsung devices.
- TricksterMod: A powerful app to change kernel features/parameters.

Starter Guide about kernel parameters/features:
If you are new to custom kernels and want to know why should you go into the trouble of flashing one, or/and you want to learn how to start visit this guide.

Ok, download and install okay. How can I make UC and OC?

Well personally I'm using Android Tuner. Pretty good.

I'm going to optimize the governors and add Hyper governor. Hopefully to see better battery performance without compromising the performance.

Great. A governor like that is really needed.
For best performance, interactive or on demand?

Just wanted to say thank you for working on a new kernel.
Am never a big fan of over clocking but Note10.1 is missing some great features like usb mount and others due to lack of kernel support. Hope you will be able to bring in more features.

I like interactive better for performance. It feels snappier.

The current ondemand is not very optimized for our device and that's why we have pegasus governor.

I've noticed that in commit 10d28c0 you've removed "MMC_CAP_ERASE" from the MMC host driver. This is called the "EMMC Brickbug Fix"- but it's not necessary on the Galaxy Note as they don't use the same EMMC as the SGS3.

Having this "fix" in will break "discard" functionality, eventually slowing down the tablet as the I/O stalls during EMMC write-block reclaims when the Flash memory fills up.

FYI

csec · Apr 12, 2013

Quick Questions:

1. init.d support?
2. Pegasus is the same as the tweaked one (pegasusq) down at s3/note 2 forums?
3. How about tweaked deadline?
4. Undervolt?
5. Boot at 1.4Ghz?

Thanks in advance!

Hmm it makes sense. I learned something new today. Will revert the commit in my next build.

Cheers!
