[Kernel][ICS 3.08] Crossbones 0.1.5 [7.18.2012] Crossbones-Fork [Post 2] [7.19.12]

This is the Crossbones Kernel from this thread: http://forum.xda-developers.com/showthread.php?t=1433544
It is not supported by the Crossbones Developers, but it was created by them. I just compiled it and brought it here.
Crossbones Kernel Information:
Current version: 0.1.5
Kernel is included in ROM and not available or supported as a flashable zip.
Source Code: https://github.com/C...ossbones_kernel
The kernel that's included in the Crossbones is a customized kernel based on Google's latest source (Linux 3.0.8). The idea behind this kernel is to provide a kernel that improves performance and the user experience but keep the stability of the stock kernel.
This kernel has been tested by all members of the team for over 48 hours and everyone has had the same result: nothing but excellent performance. This kernel is not even overclockable (yet) and honestly, doesn't feel like overclocking is needed. Every new feature added to the kernel is tested by all team members to ensure it does not affect stability and only improves the kernel. Our goal with this ROM and kernel is to have better performance and keep the stability of the stock ROM and kernel. Overclocking and undervolting will be added to the kernel eventually so if you're looking to overclock the kernel, flash a kernel that lets you overclock. However, we recommend trying our ROM with our kernel for a day and you'll see how good it is, guaranteed.
Kernel Information:
* LulzActive2 Governor
* SIO Scheduler
* Fixed bug with cpu frequencies being reported to sysfs
* Set noop to default scheduler
* Google's/Samsung latest base (3.0.8)
* BFQ I/O Scheduler (Set as default)
* SLQB slab allocator (Set as default)
* LagFree CPU Governor (Set as default and our favorite)
* BLN
* BLX
* BLD
* Voodoo
* CFS Autogroup scheduling enabled
* Other minor things I forgot I as wrote this (I'll try to take notes)
Credits:
* Google and Samsung for a great base and device
* Ezeekeel for all his awesome contributions and tweaks used in this kernel
* Paolo Valente and Fabio Checconi for BFQ
* Nick Piggin for SLQB
* supercurio for voodoo
* All the other devs that contribute into this great open source community. If I missed anyone and you feel you deserve credit please let me know
Other:
During our testing, some of us preferred using no-op as the default I/O scheduler while other chose BFQ. We suggest you test and be the judge

Download 0.1.5 compiled 7/15/12
For now it installs the modules in 2 places to make sure it is compatible with stock ics and with CM9. My testing showed that wifi would break if I used the stock module location on CM9. Looking into it.
This runs great on stock ics! I have been using it for several days on stock ics and have not seen one issue. Let me know your experience, and what you might like to see in a forked version (I may also do a fork of the crossbones kernel with other features, but with jelly bean right around the corner that idea could get derailed).
You can configure the kernel settings with NSTools.

Crossbones-Fork
If anyone is feeling adventurous, here is a test of my fork of the Crossbones kernel.
It has all the features of the original Crossbones Kernel (see first post), still attempting to focus on stability while adding new features.

Added _thalamus's IDLE2 port for S5PV210 (v0.130) (Improved Deep Idle patch) thread Go hit his thanks (or donate) button
Removed (hopefully) On/off flicker

Thanks. Start testing

FAQ's
How can I enable sweep2wake, sweep2sleep and doubletap2wake in this kernel?
- To do this, first open up a terminal. Then type:
For sweep2wake:
Code:
echo [mode] > /sys/android_touch/sweep2wake
For sweep2sleep:
Code:
echo [mode] > /sys/android_touch/s2w_s2sonly
For doubletap2wake:
Code:
echo [mode] > /sys/android_touch/doubletap2wake
Modes available:
0 - disable
1 - enable
How to set the vibration intensity with ThunderQuake Engine?
- Again, open up a terminal. Type:
Code:
echo [value] > /sys/kernel/thunderquake_engine/level
Values available: 0 - 7
Why none of my videos are playing and I'm having issues with viper4android?
- Just change your selinux mode to permissive with the help of an app called selinux mode changer. Google it.
Install that app, then open it and tap on permissive to enable the permissive selinux mode. Also tick the box that shows you the notification when the selinux mode is changed.
That's it, now after every reboot selinux will be set to permissive and all those issues will be gone.
Help me! This bug has caused me XYZ issue!!
- Simply take a logcat of the issue and then post it here.
Little OT is OK, but go too far and you will get a warning!
Thanks

Gonna try it soon, any plans on adding LG like KnockCode feature??

Plz compatibility with other roms

I love you. I'm glad you another kernel for the condor . You compiled it with any toolchain ? And d2tw is freezing the screen as in zapdos ?

Will this work with AOSP based roms?
Thanks for brining this for condor.....

Great,maybe u can try to add overclock and undervolt?Thanx
STAY ADDICTED!!!

Great work.

Woww, another Kernel for our Device, gotta try now

Unfortunately gave bootloop in slimsaber . If you like to install as the others ( zapdos , phenomenal ) I think it will be compatible with all roms . But since it is already a big project.

Tried on Sokp, Bootloop Aosp roms not supported i think......

Works great on latest AICP 10.0,no issues till now.
STAY ADDICTED!!!

@NV-Dev is this based on Linaro?

default: cfq
* added a few TCP congestion algorythms (bic, cubic, westwood, htcp, hybla, vegas, scalable, lp, veno, yeah, illinois, dctcp, lia, olia, wvegas, balia)
default: westwood
* full f2fs support, ported from official OnePlus 3/3T kernel source
* fixed some misbehaving drivers
* complete implementation of Synapse, to have everything at your fingertip
* overclock and underclock support for both CPU and GPU
* full voltage control (CPU, GPU, BUS and so on...)
* notification LED fading control
* numerous performance and stability tweaks (defconfig, fstab and Makefile)
* SELinux set to Permissive by default (can be changed by the user if he wants to)

While searching the Internet you might also find versions which aren't listed here: these are Beta versions and their changelog isn't available (but included in the one of the next stable version, so you don't miss anything).
All the changes I made are listed on GitHub.
Version 2.4.2
Code:
- update sdcardfs
- updated build scripts and recovery scripts
- changed toolchain to a better version (Linaro Android gcc 6.3.1)
- widely improved ramdisk scripts
- updated ramdisk to latest version from RR with 7.1.2 support
Changelogs for previous versions:
Version 2.4.0
Code:
- updated with latest Linux patches
- various fixes (including thermal management and network communication)
Version 2.3.0
Code:
I'm constantly working to provide a better kernel. This implies a lot of research, testing and stressing my eyes staring at code. I'm adding a lot of small fixes.
So, try to understand me if I don't always have time to report a changelog.
As always, you can check GitHub for a detailed changelog.
Version 2.2.1
Code:
Sorry if I didn't write down a changelog for the last releases, I've been quite busy.
Anyway: since version 2.1.6b there are a LOT of changes, performance, battery, stability... Just check it out (and check GitHub for a full changelog).
Version 2.1.6b
Code:
- updated busybox and sqlite3 binaries with more convenient versions
- changed optimizations, enabled safety features and possibly fixed f2fs cryptography
- getting ready for the Synapse restyling
- build the kernel uncompressed
The latter fix solves most lagging issues and noticeably improve performance over compressed version; I'll look into the kernel size issue soon!
Version 2.1.5
Code:
- ramdisk rebased over RR's one
- kernel size reduced
Version 2.1.4
Code:
- updated interactive governor with Samsung optimized version
- implemented the AMOLED flicker free patch
- updated ramdisk for both herolte and hero2lte to the one from latest LineageOS builds
- updated ramdisk to be compatible with SlimROM (untested)
- removed a few redundant tweaks
- fireactive it's on its way to debut, but still disabled because incomplete, sorry :(
Version 2.1.2
Code:
- init: added a few tweaks
- ramdisk: changes in sepolicy
- ramdisk: try to fool safetynet and fix wakelocks
- updated to DQBO kernel source
- fstab: reworked mount options
- fs: add exfat support
- fs: implement optimised and stable f2fs (from oneplus/QC8996_N)
- enabled Swap (I had the idea while looking into the OP3 sources)
Version 2.1.0
Code:
Many beta versions came before this one, and all of them had their list of fixes... I'll try to summarize:
- some configs were tweaked
- enabled init.d support
- Synapse support
- implemented elementalx
- various fixes
- faked Knox 0x0 and try to hide from SafetyNet
- switched back to cfq as default scheduler
- probably other stuff I can't remember now... I need to sleep ahahah
Version 1.2.4
Code:
- temporarily reverted to Linux 3.18.14 (and so fixed the video playback issue)
- updated mount options to reduce I/O overhead
- tweaked the kernel configuration to have better performance
- enabled additional compression algorithms and cryptography utilities
Version 1.2.3
Code:
- updated zen sched driver to version 1.1
- SELinux is now set to Permissive by default
Version 1.2.2
Code:
- now using zen as default I/O scheduler
- changed the default frequency range for the CPU
- updated to Linux 3.18.17 (still working to bring the latest patches)
- switched to a custom Makefile optimised for our architecture
Version 1.2.0
Code:
- overclock and underclock support for both CPU and GPU
- voltage control (see notes in the OP [B][**][/B])
- moved to Uber Toolchain 7.x (aarch64-linux-android-7.x)
- improved recovery installation script
Version 1.1.0
Code:
- First public release

[TUTORIAL] How to set up your phone with f2fs
1) First you have to install a compatible recovery. Recent TWRP releases can format and mount f2fs, but they don't handle a few installation scripts correcty. I recommend TWRP 3.0.2-4 by @lyapota which has the correct patches. You can find it here.
2) Then you have to backup all your data (internal storage will be wiped too, so make sure to copy ALL your files in the INTERNAL storage). So, any TWRP backup should be taken on external SD card.
3) After this, reboot into TWRP. From Wipe / Advanced Wipe check only /data, then select Change Filesystem and check f2fs. Do the same for /cache. At the moment I don't think there are ROMs that support f2fs on /system too (LineageOS, for example, forces ext4 and formats despite settings).
4) Reboot into recovery once again, so we're sure that it can mount everything.
5) At this point you're done. Flash your ROM of choice, this kernel, any GApps and whatever you want.
Reboot and profit!
ROMs supporting f2fs formatted /system will be listed here when available.

Awesome. Will this make oasp run better as there based on proper drivers etc? Can this improve the camera? Sorry for questions I have really messed with aosp on s7e yet

The idea is to have more customizations, features and overall a better user experience than the kernel the maintainers of our device provide. The changes I made are listed under features.

Dosent work with slimrom

Thanks man. Runs fine on RR and it feels smoother right away.

I'll have to look into the sources to see if they did specific changes to the kernel.

Am I right in saying kernels are the main things that help battery life

Do I just Flash the .zip in TWRP to install kernel?

Yes. It's a simple .zip that just flashes the kernel (not rooting or anything, but maybe in a future I can upgrade to an aroma installer).

I just posted in another thread regarding use of your kernel
https://forum.xda-developers.com/s7...extended-rom-v3-1-t3559696/page4#post71203867
I had hoped that using your kernel would allow for full functionality of Magisk -- unfortunately it did not
I really think that since Magisk works well with Stock ROMs it has to do with repacking of the boot img
Hopefully you would be willing to touch base with @topjohnwu to work on obtaining full Magisk compatibility with AOSP Galaxy S7 Edge ROMs
Thanks for you work

wow! thanks so much was hoping for a custom kernel for AOSP! i hope you will consider adding undervolting and synapse support. Thanks for your efforts!

Yes there is a link for both S7 and S7 edge.
EDIT: there is a separate thread for the S7 (flat) here

The next in my to-do list are underclock and overclock, followed by voltage control.

I flashed it right now on RR . and im impressed as its smooth af. Im not too sure about battery life , but i fully admit its improvement on performence . good job dev . keep it going
