TKT will work, but it will FC on the tuneables tab. Your settings will stick, but the constant FC thing can get a bit annoying. Franco's app works perfectly though, and I'm sure the others do too (I haven't tested Glados or Trickster though). Give me a second, and I'll link to a post I left in the Rootz thread, regarding some different governor/scheduler setups, that may be helpful to you. :)

Edit: the link seems to just take you to the OP, so here's my entire post...it's super long...that's why I just wanted to link to it.

-----------------------------------------------------

Ok guys...here are some of my findings, based on testing different governor/scheduler combos. Your results may vary, depending on how you use your device:

*First...do a clean flash (cache and dalvik wipe) to avoid any potential boot issues.

Interactive/sio: a trued and true combo, that's both quick and responsive, and decent on battery.

On demand/ deadline: another old combo, that many people prefer for its low battery consumption.

SavagedZen/CFQ: slightly slower than Interactive/sio, but very smooth, and provides great battery. If you don't care too much about benchmarking, and want a great all-around setup...this may be a good choice. *[Best for battery...by a LOT]

Interactivex/sio: slightly better battery than Interactive/sio, but similar overall performance. *[Fastest combo...does give micro lag at times]

Lulzactive/sio or deadline: choose a scheduler based on how you want your device to perform. Lulzactive is a mix of Interactive and Smartass, so pairing it with sio will give you faster overall performance, while deadline gives a little more smoothness and battery.

Intellidemand/deadline, sio, or CFQ: Intellidemand has some GPU scaling properties to it, that fit perfectly with JB's Project Butter code changes. Mix it with deadline for better battery, sio for speed, or CFQ for a nice balance.

*My personal setup is Intellidemand/CFQ, as I've found it to be the best for me. I get good battery, it's great for gaming (tested with Order and Chaos, Dungeon Defenders and Modern Combat), stays pretty cool, and stays stable.

***Some Tweaks {color and performance} * * *

ROM Toolbox Pro:

(Under systctl tweaks):

vm.dirty_background_ratio = 70

vm.min_free_kbytes = 4096

vm.vfs_cache_pressure = 30

vm.oom_kill_allocating_task = On

(Under SD boost): set to 4096

Franco app color tuning:

Color multipliers: 157, 144, 200

RGB Gama: -4, 0, 4

Trinity's Contrast Interface: -13

OMAP4 Gama Interface: 1.4

Disable CAB: checked

*Again...these are just what works for me. Try them and play around with them if you want. Hope this helps. ￼

Here is IMO, the best governor/scheduler resource guide in all of my internets! If you want to learn a bit more, check it out.

There's a setting that allows you to "set on boot" in Trickster Mod so you don't have to set everything up again :)
[Samsung Galaxy Nexus] shinydesert:
Woooww,what a great reply man. Thanks a ton for such a great post,I am gonna keep the whole post,great recommendations.

Regardless of what I try once the screen off frequency goes below 307 mhz or 307 mhz the device stops getting emails, must be a very low speed.

I have been testing different kernels though,even the ones which min. frequency is 384mhz TKT shows 307mhz as the min, but anyways I will keep playing with it.

Thanks Mr. Encyclopedia for your help. :good:
[Samsung Galaxy Nexus] pnut22r:
Can someone help me out with an explanation on these? And how they should be set?
[Samsung Galaxy Nexus] jjhiza:
What governor/scheduler setup are you using?
[Samsung Galaxy Nexus] gm007:
Can't you see he is using ondemand governor.

Anyway, nice work and that fast our phone should be...

this kernel is great,hoping the battery will be also great :D
[Samsung Galaxy Nexus] pnut22r:
Yeah, it says OnDemand at the top. I'm also using deadline
[Samsung Galaxy Nexus] jjhiza:
Lmao! I had a brain fart...I thought the On demand label was the name if the kernel control app. :p For On demand, those settings should be fine...I don't mess with those too much.

My sampling down factor is 25, and my Up threshold is 95, but I'm using a Intellidemand/cfq setup, which scales differently.

So impressed with this kernel!!! I've used Franco, lean, I think all of them and this one totally rocks. I noticed something after I flashes it though.... my boot loader is now locked. Didn't see the open lock at startup, so I did the 3 finger salute and it states boot loader:locked!

But everything is still running as normal. I can still flash ROMs and kernels with no problem...strange.

Just need to sit down and tinker with it...
[Samsung Galaxy Nexus] bbedward:
I updated the WiFi drivers to then latest bcmdhd with a lot of then updates from android 3.4 + omap 3.0.

All seems good, tested on 4.1 and 4.2 Roms.

Well see if it fixes the issues some users were having.

The update was pretty substantial, a lot of the driver basically rewritten. I kept in some of the extra android pm features as well.
[Samsung Galaxy Nexus] gm007:
Thanks for your hard work,but you have to know that the new drivers doesn't work with wep security.Some users will report it as a bug,hope you are aware of it.

By the way wifi is working fine here and reconnect automatically.
[Samsung Galaxy Nexus] gnlcp:
I don't know why after flashing v8 4.2 on ota 4.2 rom I get bootlop on Google logo...
[Samsung Galaxy Nexus] Febby:
Thanks for this great kernel mate. loving it!
[Samsung Galaxy Nexus] bbedward:
Oh thanks for the heads up. I won't worry about wep if it improves the driver in other ways.

My ultimate suggestion for people who use wep is to not use it :)
[Samsung Galaxy Nexus] Savant:
Great words because wep gets hacked easily and businesses shouldn't use it because it can lead to problems down the road.
[Samsung Galaxy Nexus] bbedward:
I find most people don't use wep anymore anyway, if I convert one person to WPA/WPA2 by not supporting wep that's probably a good thing :)

I did confirm v9 does not work with wep, so the above statement is indeed correct.

I hate to say it, but I'd rather have the best for 95% and exclude the few who need wep instead of having a lesser product for 100%.
[Samsung Galaxy Nexus] bigbear6708:
Just want to say I tweaked interactive gov a bit to try and tame it...I changed above high-speed freq to 60000 and the high-speed freq to 729. Still smooth and battery is a touch better. Just wondering that since I didn't see an enable option..is input_boost enabled by default?

Notice the screenshot..spending most time low...but scaling nicely as needed!
[Samsung Galaxy Nexus] in1400:
100% Agree! :good:
[Samsung Galaxy Nexus] ak:
this is my experience with new wifi drivers:

My phone don't lose connection when screen off

wep is not a bug but it's not supported

the wifi tethering for me doesn't work (only with 4.2 roms)

PS:

Very good work guys!

hi, is this kernel already undervolted(if there is such a thing) ? i find my nexus restarting even after applying just 25mv....using system tuner to undervolt..
[Samsung Galaxy Nexus] gm007:
This kernel is well calibrated, no need to undervolt more,leave the default setup.
[Samsung Galaxy Nexus] bbedward:
Its already undervolted. You can try disabling SR and seeing if you can squeeze more that way

Bootloop after installing ZenSeries kernel for 4.1

After installing ZenSeries kernel for Android 4.1 (v8) my GN got into bootloop. I tried flashing this kernel again without wiping cache and Dalvik, as recommended in this thread, but the bootloop happened again. I had to flash the current kernel (FuguMod v935) in order to make my GN using ParanoidAndroid 2.54 ROM (based on CM10 4.1.2) boot normally.

I know some people avoid the bootloop issue reinstalling ROM and then ZenSeries kernel, but is there any other way to install this kernel? What about the cleaner script included with ZenSeries kernels? Thanks in advance.
[Samsung Galaxy Nexus] since77:
Hi Bredwardine, how do I disable SR.? Thanks
[Samsung Galaxy Nexus] bbedward:
The boot loops or inability to boot is due to the Roms ram disk setting something that doesn't place nice.

That's why some users say flashing a kernel with a custom ram disk, such as Franco/,Lean first, resolves the issue.

You can disable SR in an app such as trickster, glados, etc. I think anarkia has in his thread how to do it via terminal

Do you use hotplug governor? It gaves this type of problems to me.
[Samsung Galaxy Nexus] bigknowz:
Weak Signal

Is anyone noticing an issue with their mobile signal? My phone seems to lose signal more often than when I was on stock kernel. Running v8 with Bugless Beast 10-30 build, baseband I515.09 V.FF02 / I515.FG02
[Samsung Galaxy Nexus] WoodroweBones:
I believe this is a 4.2 bug. It seems to have something to do with Wi-Fi. As an example if you leave your phone off Wi-Fi the signal will probably be pretty steady. but once connected to Wi-Fi both start behaving erratically

There isn't one that's "best"... it's all a matter of personal preference. You can check the link below for a detailed explanation of what certain governors and schedulers do. It's really a great resource, and will help you make the choice for yourself. :)

[Samsung Galaxy Nexus] taz1458:
Could anyone give me some pics of their voltage? Would like to undervolt but don't want to try it myself. Thanks
[Samsung Galaxy Nexus] bigbear6708:
This kernel is already insanely undervolted... going any lower, IMO, won't give any better results
[Samsung Galaxy Nexus] jjhiza:
Agreed. bbedward has undervolted the kernel a lot... going any lower could cause instability and/or loss of functionality. Even if you don't experience issues, the benefits of undervolting are negligible.

I've had first hand experience with this, as I used to run and undervolt Trinity, before Zen was released. I spoke to Simms regarding a running conversation he and morfic had with Franco, and he explained to me that lowering voltages on an already undervolted kernel, could cause major problems. Since then, I run the preset voltages... but if you want to try undervolting more, I'd suggest lowering values in steps of 5MHz, until you find settings that work for you. :)
[Samsung Galaxy Nexus] taz1458:
Think ill just stick with it then. LOL. Just got my nexus running today(waiting on a sim card since im an hour from a verizon store....) and so far its freaking awesome. cj has aliendroid on it. Im debating about flashing a stock 4.2 rom just to get that experience.
[Samsung Galaxy Nexus] jjhiza:
Personally, I'd wait on Google to either patch 4.2 or for them to release 4.2.1. I jump between 4.1.1 and 4.2, simply because I need to test the kernel builds for you guys and gals, but 4.2 is (IMO) a very sub par update in a lot of ways, and isn't worth flashing if you need a daily driver. The ROMs I've used are stable, but there are some issues with it that annoy me to no end...and then there's the annoying sdcsrd/0 issue that comes along with 4.2...It may simply not be worth your time, but obviously, it's completely up to you. :)

[Samsung Galaxy Nexus] gm007:
Really i don't know how those settings work,you need little research,there is lot of explanation about it.i prefer the default kernel setup with interactivex,its doing great for performance and battery,but you can try this settings if you like playing a lot :D

You could create CPU profiles in Rom Toolbox Pro. (Not sure if Lite version allows profiles, I think it doesn't.)

Or there may be some other applications (Tasker-like) that enable you to auto change your max frequency.

[Samsung Galaxy Nexus] bbedward:
Hey guys, hope everyone had a good holiday (at least those who recognize it :) )

Things slowed down in recognition of it, but have some nice things planned yet for v9 .

I'm going to make the kernel 4.1+4.2 compatible by adding in a sysfs for the Bluetooth driver. That way a "4.1 Bluetooth compat" value can be set to fix the driver. Its a slightly better solution than 2 kernel builds :)

Is there any recommended governor/scheduler?I would like to use InteractiveX,but i remember huge problems at Lean and this govervor...
[Samsung Galaxy Nexus] Bl4ck3urn:
What kind of problems?
[Samsung Galaxy Nexus] bbedward:
interactiveX is fine, and is actually the default governor. It is interactive + some suspend/wake features and has CPU hotplugging features (so should conserve more battery than interactive)

As for I/O schedulers, they're all pretty much safe bets. I'd stay away from fifo, unless you want to test some I/O operations on a strict FCFS basis, or you have a situation where pure FCFS is ideal.

FIOPS/SIO/zen are the ones that claim to be optimized for SSD/Flash storage
