Omega 3 Kernel

Hello everyone! This is my first custom kernel, is based on source of motley with various features from franciscofranco, metallice, faux123, intersectRaven, stratosk and kasperh.

Works on Nexus 7 and Nexus 7 3G.

Features from motley:
  • Asus\Nvidia\Google Linux 3.1.10 base. All stock features are supported (camera, OTG, NFC etc.)
  • OC to 1.6GHz (optional)
  • Voltage control - be careful to not save the setting on boot until you are 100% sure!
  • GPU OC to 446Mhz
  • Dynamic EDP - allows EDP to remain enabled (safer), but with an added simple temperature throttle switch (based on Asus Prime)
  • ZRAM - must be enabled by a script
  • initramfs - insecure (your ROM must have busybox)
  • CIFS/UTF8, NFS, NTFS r/w, TUN - built-in, no need for any kernel modules
  • fsync sysfs enable/disable switch (defaults to fsync enabled)
  • kexec with hardboot (for supporting Linux/MultiROM)

New features:
  • Compiled with latest Linaro 12.12 - GCC 4.7.3
  • 7 I/O schedulers - SIO, V(R), CFQ, NOOP, deadline, ROW(default), BFQ v5r1
  • 13 Governors - Interactive(default), Performance, Ondemand, Userspace, PowerSave, Conservative, Lulzactive, SmartassV2, PegasusQ, Wheatley, InteractiveX, OndemandX, Lazy
  • TCP setting: cubic(default), reno, bic, westwood, highspeed, hybla, htcp, vegas, veno, scalable, lp, yeah, illinos
  • Optimized misc: SHA1, AES, lib string/memcpy, ARM RWSEM algorithm, OTG unplug and many many others :p
  • Update ZRAM (3.3), ZCACHE (3.3), Android Binder (3.3), Lowmemorykiller (3.4), Logger (3.4), Time GPIO (3.4)
  • Dynamic Sync Control
  • Support init.d scripts
  • Jay's Recipe for Buttery Goodness integrated (without init.d script)
  • Tweak to random entropy (just some more random data avaible)
  • Much more Ram avaible
  • GPU Overclock Interface
  • CPU LP Overclock Interface

2013/01/16 - r4
  • Removed Thalamus ARM Generic Hotplug (much more battery)
  • Revert Interactive governor to 3.1 (more balanced)
  • Revert Android staging drivers to 3.4 (fix lowmemorykiller bug)
  • Fix compaction for lowmemorykiller 3.4
  • Revert VM_MAX_READAHEAD to 128 (1024/2048 are useless for battery/performance)
  • Added GPU Overclock Interface
  • Added CPU LP Overclock Interface
  • Tweaked Ramdisk for much more Ram avaible (to see the differance type free on terminal before/after flash)
  • Compiled with -O2 (in testing)

2013/01/14 - r3
  • Added InteractiveX governor
  • Added OndemandX governor
  • Added Lazy governor
  • Tweak to random entropy (just some more random data avaible)
  • TCP setting: cubic, reno, bic, westwood, highspeed, hybla, htcp, vegas, veno, scalable, lp, yeah, illinos

2013/01/12 - r2
  • Interactive governor from 3.4
  • Tweaked ramdisk
  • Support init.d scripts
  • Jay's Recipe for Buttery Goodness integrated (without init.d script)
  • Kernel compressed with XY

2013/01/11 - r1
  • Initial release.

Thanks to all XDA developers :)

I'll test this out on cm10.1 should work if you built from motley source

EDIT: Is it okay if i cook this in my ROM? Thanks.

I tested it out on sgt7 (cm10.1) and it was stuck at the max freq. Couldn't get it to scale down no matter what governor I chose or after rebooting. Went back to lean kernel and all is well again. Idk what happened?

Ok, no problem for me :)

Have you tried if with motley too there is the same problem?
OK, tested. But according to antutu is a little bit slower than motley one, but anyway I will keep testing for a couple days more.

Try with performance gov because I've optimized interactive gov to be less aggressive scaling at 1Ghz (hispeed_freq) for save more battery :p
Remember that a difference of 400~ points is normal from one test to another and if you just rebooted, wait that media scanner finish its work.

ehi Brisma,good work man!tried the kernel,smooth and fast!benhmarks are a bit lower,but real-use is great!
Really like what you cherry-picked,i think i'll stay with that for now!:p
keep up the good work!

same here...back to franco for the moment...
i have tried different governors and parameters but always at max freq.

ondemand or interactive performance and conservative are those you can play with.
Others are always giving you problems. Other governors are more buzzwords than anything else.
At least it's my opinion...

And what about SmartassV2? It gives great battery life and good performance not like ondemand(not so good performance) and interactive(not so good at battery life).

Just my opinion, for me no need to them. I use interactive when gaming an conservative for other things.
And my battery is great and i always keep stability.
The only kernels i use are trinity and franco kernels because of that.
To much governors, schedulers, patch and mods always gives you stability problem.
I do not denigrate any kernel or kernel devs, i just love when it's clean lean and simple.

    Download on first post.

    This is a test build compiled with -O2 and some reverted driver to see if fix the bugs of excessive use of the cpu and the forceclose without warning.
    For the ram tweak, to see the difference type free on terminal before/after flash the kernel :)

    Okay, i feel like a kid asking to santa :p could you please add lulzactivev2 and ondemandax governors? Specially lulzactivev2 because it's a multi core governor and uses wisely hotplug feature.

    Lulzactive was already v2 :)

    Did you try to build the same kernel but without all those scheduler, governors, zram and other things people love (i can understand that).
    Just to see? I'm sure your kernel will be ten times more powerfull.
    And it will be a real plaisure to test it and see the difference! ;)
    Simply don't use these feature, they aren't active if you don't select them :p
    You need to post a link to you source. Complying with GPL is something we do around here :) Wouldn't want the mods to close it now.

    Oh and just a tip - o3 is a bad idea with kernels. Leads to a bloated and slow build. Its better to use o2 and cherry pick some o3 flags here and there rather than all of the ones included by o3.

    I'm sorry, but for now my internet connection don't allow me to upload source (I've an internet key with 2Gb data/month) :(
    But if someone want source, just ask me, no problem, I'm happy to share them :)

    IMHO, for the -O2/-O3 is a complicated situation, someone says that -O2 is better for stability/performance because -O3 isn't ready/useful, other says that -O3 is just ready from 1 year and can incrementate performance... Trying both I noticed that are both stable and performance are the same, but -O3, in my test, is 5%-10% more powerful in benchmark that -O2...so why don't use it if it is stable :p ?

    Sorry for my poor english, I'm italian :(
