Tuna is the codename for all variants of the Galaxy Nexus so this kernel can be flashed on all Galaxy Nexus versions.
Yes but without the new user space libs the updated driver in kernel won't work . it may be possible to replace all the necessary libs with anykernel2 , I might try if I get some time .

Pardon me.
Nothing wrong with posting
Old software is still good software! In fact, I wish we had recorded what the best 4.2/4.3/4.4 builds of ROMs and kernels were, and then stickied them at the top of the forum. That way you wouldn't need to go searching. I used to run AOKP 4.2 and it was great!
And I run CM 12.1 now and it works great too. A lot of people are running CM 13 and say it's good. That's all I can help you with. =)

To quote @Hetalk from the second post on the first page,
What's the difference between these three kernels?
- DirtyV versions are the ones where your 1080p recording works.
- SR versions are the "SuperRAM" versions where a lot of RAM has been reclaimed. You get more RAM, but you need to give up 1080 recording, as a trade-off. If you plan to use this one, make sure you change your camera video recording to 720p instead of 1080p. Latest kernel versions will make this change automatic.
- The 3rd one is @bsmitty83 's own build that he's running for his tests. You can use this and feel like a developer.
This one might not have all the governors/freqs/io/settings that you can't live without, so be prepared to be surprised.

Hello everyone , this is my personal Android 4.4 kernel . I figured I'd share it with everbody since it seems to be working good . anyhow flash it if you want ,
ALL credit and thanks should be directed to @styr , the Vanir Devs , and any developers who's commits I used ( alot )
The Basics,
Based on Linux kernel 3.0.101
- Forked from jimsth/vanir_tuna
- Added some things I use ( governors and schedulers ) , some performance commits
- Built with @Christopher83 's custom optimized- Linaro 4.9.1 toolchain -O3 optimized, graphite , link-time opt.
- Ramdisk made by @osm0sis

F2FS Updates !!
Just to avoid multiple questions on this subject, I'll add f2fs related updates here,tomorrow.
Please point me to stuff outside this thread, as basically this is the only thread that I read everything on.
[*]What is this "f2fs" thingy?
Read more about this awesome file systems here
[*]How to use this f2fs?
Read this and this and this (nice workaround) . If you understand it all, go ahead and have fun.
There's a small guide by @p34rp34r here.
Another awesome guide for f2fs and our device. by @burstlam
Again, if you don't understand what you're doing, DONT DO IT.
[*]How to test f2fs thing?
Read this post
[*]Compatible ROMs?new
@aosp and @bsmitty83 have been using vanir's commotio builds for f2fs test on this thread
There's a SlimKat f2fs unofficial version here
I've managed to get a paranoid f2fs version. See post here
Here's the most beloved Liquidsmooth f2fs version by @Punkiderma
F2FS converted OmniROM by @pianistaPL
Our own @poo706 has ported and improved upon an awesome tool that would convert most ROMs to f2fs compatible ROMs. Jump to it's own thread for more info.
[*]More questions?new
Why not? Jump to the F2Fs Q&A thread by @jhonnyx .
Feel free to read and search thru the thread. Ask questions that you still are unsure of.

Kernel FAQ :
- Whythree kernels?
More choice for different users and different user activity.
[*]What's the difference between these three kernels?
DirtyV versions are the ones where your 1080p recording works.
SR versions are the "SuperRAM" versions where a lot of RAM has been reclaimed. You get more RAM, but you need to give up 1080 recording, as a trade-off. If you plan to use this one, make sure you change your camera video recording to 720p instead of 1080p. Latest kernel versions will make this change automatic.
The 3rd one is @bsmitty83 's own build that he's running for his tests. You can use this and feel like a developer.
This one might not have all the governors/freqs/io/settings that you can't live without, so be prepared to be surprised.
[*]What are recommended kernel settings?
Follow @Nephilim 's kernel settings. Here they are
[*]Anyone got any nice init scripts to automate neph's settings?
Yes. @büscher got it all covered for you here Thank him.
[*]Can I use on x ROM?
Sure. If it doesn't work, let people here know. There might be a workaround.
[*]How to submit a bug?
Post a note here with relevant information(what you were doing when x happened, screenshots, how to replicate, logs, etc)
[*]What is this log that people talk about? How to take a useful log?
Read this
or use syslog app from play store.
[*] Does Touchwake/PGM/<your favorite touchmanager> work?
This kernel has an inbuild touchwake. You can set it using a kenel settings application (eg. TricksterMod).Sadly, not any more.
It's also got the required modules to support <your fav tool>. You need to ask the app developer to include support for dirty kernels.
Latest smitty version has touchwake removed, so that PGM developer can update his app to support dirty kernel.
PGM fans, see and thank this post
[*] What is the difference between linaro and sabermod?
The difference is just what toolchain was used to compile them. Linaro is a highly optimized custom built toolchain, and sabermod is based off aosp toolchain but with lots of extra patches for optimization
Presently, @bsmitty83 is using @metalspring 's custom toolchain to compile all dirty versions. And, they come with a ramdisk, specially made for all of us, by @osm0sis
[*] Is Fast Charge broken? I can still access my files with fast charge on!
Nope. It's not broken. With some super voodoo now you can access your files along with fast charging your battery. But, do it only if you are in a hurry. Fast charging might not be good for battery life(citation needed).
[*] My Antutu with <insert kernel name here> is bigger/better/wider/thicker than yours.
Wateva
[*] Can I try this on my favorite 4.2/4.0/2.6/0.1.1 ROM ?
Check this post by @osm0sis on how to accomplish this not-so-difficult task.
[*] When will the next version be released?
Now. Just check the last couple pages, and you'll see @bsmitty83 's got another one for you. :victory:
[*] Latest version does not have my favorite io/gov. Why he no love me no more?
Most likely, smitty forgot to add it in. Just put a comment about the missing item and he'll put it back. In the meantime, try out other io/gov/freq/etc. Maybe you'll find a hidden gem (like @Nephilim found illinois)
[*] I don't like the kernel splash screen (coming soon)
Eyelids are provided for a reason. Close them for a couple seconds after turning on your phone and you'll get rid of the bootsplash
[*] What is this synapse thing that I hear about?
Synapse is a kernel settings tool, that you can use to tweak kernel settings that smart people on this thread talk about. @osm0sis has been instrumental in making this tool work for our beloved kernel. Thank him for this free tool.
And Yea " 720p works on all of the builds. ":highfive::victory::good:53Some init.d script's I made for DirtyV
Download Nephilim's settings all-in-one script (latest changes: 14.04.2014 - updated settings)
Download büscher's settings all-in-one script (latest changes: 17.04.2014)
Download Lowmemorykiller whitelist script -> Please have a look here for lowmemorykiller whitelist explanation.
Link to Nephilim's Settings
changes:
10.04.14: new minfree settings in buescher's script
14.04.14: set OMAP gamma contrast to 0 - gets rid of sync_lost
16.04.14: new minfree values for new SmittyV, min freq @ 190MHz, max screen off freq @ 525MHz, sioplus@512 as new ioscheduler, 525MHz as input_boost_frequency, 700MHz as high_speed_frequency
17.04.14: reverted to 920MHz highspeed_freq
Büscher's settings and differences to Nephilim's Settings (Kernel Stock where nothing mentioned):
- CPU Max Frequency @ 1500MHz
- Max Screen Off Frequency @ 525MHz: To avoid music glitches with Poweramp - lowered as it seems to work way better than on previous versions
- Min Frequency @ 190MHz: works good
- Min Screen On Frequency @ 230MHz: to avoid choppiness with screen on
- Interactive Governor
- Hispeed Frequency @ 920MHz: Frequency which to initially ramp when CPU load hits the value specified in go_hispeed_load
- Above Hispeed Delay 20000: When speed is at or above hispeed_freq, wait for this long before raising speed in response to continued high load.
- go_hispeed_load @ 85: more aggressive than stock - and not 'being mean' to the governor
- Input Boost Frequency @ 525MHz: Frequency which to ramp when you touch the phone
- boostpulse_duration @ 500000: min time at input_boost_freq after touching the phone - less aggressive and more battery friendly
- min_sample_time @ 10000: The minimum amount of time to spend at the current frequency before ramping down - gives the cpu the possibility to ramp down frequencies earlier - more battery friendly
- target_loads @ 75: the lower the target load, the more often the governor will raise CPU speeds to bring load below the target - more aggressive than stock
- timer_rate @ 10000: sample rate to increase freq - overall snappier feeling but less battery friendly
- timer_slack @ 60000: maximum time to allow deferring of timer_rate - just raised to a 10'000th
- sioplus as I/O Control
- Read Ahead Buffer 512: new measurements lead me to this - you may want to try other values as my storage seems to be borked
- Async_Expire 2500: Deadline for asynchronous requests
- Sync_Expire 304: Deadline for synchronous requests (Default ~10 times less than async_expire)
- fifo_batch 0: Number of requests to issue before checking for expired requests
- TCP Congestion Control westwood: best results in Switzerland
- Enable Content Adaptive Brightness: Saves Battery
- Enable Fast Charge: Lets you charge your phone faster on USB - doesn't break media transfer anymore
- Overclock GPU to 384 MHz: Same voltages as 307MHz - more battery friendly if you don't need your phone for gaming
- Headphone Volume Boost is set to 2: I don't use Nexus Louder and just set this to two - can cause music stutters, set it to 1 if so
- Enable High Performance Sound
- Dynamic FSYNC: disabled: I had data loss more than once because of this
- Multicore Power Saving 0: I can't get anything out of this
- Apply SmittyV 4/6 default minfree settings
- Disable ZRAM
- Vibrator strength 70
- more options available
Androbench screenshot for comparison:
Quadrant Benchmark for comparison: (my settings with GPU@512MHz)
How to Install:
1. Download scripts and rename to no extension
2. Put the script to system/etc/init.d
3. Set permission to 755 ( rwxr-xr-x )
Some important lines:
Not all of Neph's Settings are present in my scripts (undervolt, blx, vibrator strength) as I don't use them.
undervolting with init.d scripts is to risky for me, the rest can be added if wanted and if I find the right path to the parameters.
Please check frequently for changes
All benchmarks done with SmittyV-NoMeM { 2/28 }
Credits:
@Nephilim for the hard work finding the best values for our phone!
@osm0sis for helping me out and explaining stuff the easy way
Francos Dev team for disabling sysctl.conf lines49
I only accept donations from the thanks button . man , this is a hobby , I do it for fun and I want to keep it like that . people on here have donated enough to me in knowledge :beer:
