Nexus 7 Kernel - Nexus 7 Q&A, Help & Troubleshooting

Hey, do you recommend any Kernel control apps (setcpu, EG) for use with the Nexus 7 on Enhance Stock 1.2ghz? I am a bit confused what happens if I am not running any apps to set the cpu speed, does it just choose on it's own? or what.
My ROM: http://forum.xda-developers.com/showthread.php?t=1830016
The Kernel I want to install (currently Stock) : http://forum.xda-developers.com/showthread.php?t=1804374 (Max Stock Enhanced 1.2)
Please give me suggestions!
Thanks for the help.
-Eric

The kernel has default settings just like a stock kernel, and without a management app it just uses the defaults.
I can't remember if Scotts ROM had built in performance settings in the regular settings menu.
I recommend avoiding set CPU, and I would run system tuner, and just ignore everything but the CPU category if it seems overwhelming at first to see everything the app can do.
CPU master is much more basic and simple and user friendly and although it doesnt have nearly as many configuration features, its much more simple and to the point.

can someone explain this Kernel stuff

I rooted my MY4G and installed IG last week...nothing else..i have added some little stuff like setCPU, terminal emulator, etc.
I keep reading about dif Kernels and i have no idea if i need to install one or what they do over the ice glacier i all ready installed.
explain all this too me please.
thanks
Different kernels just have different features. The stock kernel that comes with Iced Glacier is already a custom kernel (Gr8Gorilla's 1.8 GHz v.05). If I remember right, this kernel didn't have UV (Under Volting). There are many different features offered with each kernel choice. Such as:
OC (Over Clocking support): This just allows you to go higher than the factory settings.
UV (Under Volting): This means the kernel's voltage tables have been lowered to attempt to save battery life.
MinMax: This feature keeps the CPU running at the set minimum and maximum settings.
Smartass: Scales the CPU "intelligently." It acts in lieu of SetCPU profiles by scaling the processor down for screen off.
There are also different scaling types enabled in different kernels. Just give them a flash to see if you like them! Make sure you remember to do a nandroid first. Happy flashing!

[Arrows - Guide] Best Aosp GB & ICS Roms [Updated - 1/22/12]

Feel Free to post and give feedback ^_^
Also feel free to Vote the thread ^_^
Q&A is in Post 2
_____________________________________
Hi Everyone, Arrow here and this is my guide to find what is the best aosp setup for your evo or android. It is true when people say "every phone is different." However there is an average of people that get similar results. At the moment people have different interest such as some people want performance and some want to improve their battery life. Of course certain people want both but only some get both.
*Remember what i put here is an average and may be different on your evo*
AOSP GB ROM'S: Ok so to start off, these are aosp roms still being updated as of now.
CyanogenMod 7 (CM7) - The most famous aosp rom out there, all or almost all other aosp roms are based off of this rom. This rom has a stable rom and experimental nightly builds. Anyone will tell you that you can't go wrong by choosing this rom. and believe me you will enjoy it.
CyanogenMod 7 Thread
Miui - This rom has the longest battery life and is very customizable. This rom is based off of CM7 and is an excelent rom. However unlike CM7 this rom does not have 4g so if you are willing to sacrifice 4g then believe me this is your rom.
Miui Thread
Gingerbread Evo Deck - Ok so although CM7 is amazing decks gb rom has said to be the exact same thing but giving off better battery life. other then that it is pretty much the same thing with some minor tweaks and some bloat ware removed.
Gingerbread-Evo-Deck's Thread
Xplod E4G - Team Nocturnal designed this rom and it is pretty much CM7 with the Sony Launcher + their apps. This rom will give your phone a nice cool feel that other people don't have. If you like a lot of eye candy then get this rom because it is CM7 just with a different look and feel.
Team Nocturnals Xplod E4G RLS1.2

using Xplod: there's a 50/50 chance the new tiamat kernels [4.0.7+] may not boot, in that case, they should use 3.3.7.

ICS(mod7) - Team Blaze designed this rom and you can consider this rom like Xplod E4G, a rom just like CM7 with some minor tweaks but with a different look and feel. None the less this rom has something very special this is the closest rom to being like ICS (Ice Cream Sandwich). I 100% support this rom because they are doing the best they can to make this rom look and run as smooth as ICS. so if you want to look like your ahead of the game definitely get this rom.
ICS(mod7) Thread
AOSP GB Kernels: These are three kernels that i know of, if you know of more please let me know and i will add them.
Tiamat 4.1.0 - This is the latest kernel made by Tiamat and this is the only aosp kernel still being updated. This kernel on average gives people great performance but lacks on battery life. The main Governor for this kernel is SmartassV2 which is a balanced governor, good to turn on your phone and good to use on a normal day to day bases. For this kernel i do recommend using this governor. It does have SBC and Non-SBC kernels. *Side Note* (Some people say Tiamat 3.3.7 works better for them and is also known as the LEE Kernel because it was awesome like Bruce Lee and looks like Lee backwards [337])
Tiamat Website I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen - This kernel is no longer being updated, however it is still amazing this kernel seems to be Tiamat's competition. Where Tiamat lacks on battery Savaged-Zen does not. However it's performance is not as good as Tiamat. This Kernel comes in two version BFS (Brain F***ed Scheduler) and CFS (Completely Fair Scheduler). BFS is said to give better performance and CFS is the normal kernel. This kernel only comes with SBC however you may download "SVZ Manager" which will allow you to turn SBC on or off. The main governor for this kernel i believe is on demand However i use smartass and a lot of people us InteractiveX.
Savaged-Zen CFS sbc I also put the Zips in the Attachment (At The Bottom)
Savaged-Zen BFS sbc in attachments (At The Bottom)
SVZ Manager I also put the Zips in the Attachment (At The Bottom)
GoDm0de - This Kernel was made by toastcfh and is no longer being updated. It is non-sbc and in my opinion definitely the best non-sbc kernel. This Kernel has insane battery life and a pretty good performance. If you do not want to use an sbc kernel i recommend for you to 100% use this kernel. The Governor for this kernel is set on on demand (i think) however i got the best battery/performance using Interactive.
GoDm0dE Kernel I also put the Zips in the Attachment (At The Bottom)
AOSP ICS ROM'S:
ICS rom by: the_Plattypus and it is still in Alpha testing. however the development for this rom is moving really fast so hopefully a beta will come soon.
EVO 4g Ice Cream Sandwich from source
ICS-evo-deck: This Rom is by kushdeck, After testing out Decks ICS Pre-Alpha 4 & 7 rom i conclude that although it is a alpha it can easily be used as a day to day rom. extremely fast and very snappy. only thing that i found not working was the camera. (Now on Alpha5)
[ROM][ICS][1-11-12][WIP] ics-deck-evo [alpha5]
All Decks ICS Pre-Alphas
All Decks ICS Gapps
AOSP ICS Kernels:
Jaredthegreat ICS - jared has the most advanced ics rom which is in beta 2 but does not have a working camera to check this rom go here:
[ROM's] -ICS- 4.0.1-4.0.3>[AOSP]<--~B.2.0~
Will post them when they are released!!!
Rom Manager/Kernel Manager:
Rom Manager: This is an app from the android market and is extremely useful for pretty much anything. you can back up your rom, you may go into boot loader and you can check if certain roms such as "CM7 Nightlies" have been updated. However people do prefer Amon Ra for flashing, which is another plus of Rom Manager it allows you to flash alternative recovery, which will flash Amon Ra for you.
Kernel Manager: This app was working before but has stopped now, however if it does start working again what it had was pretty much all the kernels that you needed for any rom. this app would allow you to flash a new kernel immediately by going to the kernel you want to flash.
Reserved
Q&A:
Q: What is SBC?
A: SBC stands for super battery charger. SBC is trickle charging, It stops your battery from dropping from 100% to 90% right when you take it off the charger. Some say that it harms your battery but i haven't seen any harm and plus it only costs $5 to get a new battery on Amazon.
Q: How to set up and flash your roms and kernels?
A: well my friend "Crossrocker" made a guide for this with everything you need. so just click to go to his thread. [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q: What is the difference between governors?
A: This Thread by "RJackson" explains it all:SetCPU governors (explained)
But if you're too lazy to click it here they are:
As explaind by RJackson:
ondemand - Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative - Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance - Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave - Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive - The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
As explained by MDJ:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245. No need for sleep profiles any more![/QUOTE]
As explained by teh roxxorz:
Lagfree - like the performance governor. It will scale the cpu to higher frequencies when needed, but not to 100% like performance, so you'll get a lil better battery out of it
SmartassV2 - A smarter smartass governor. Code was re-managed/removed to make it more optimized, and have better scaling performances
InteractiveX - a better interactive governor I believe; low scale cpu settings, for texting, browsing, ect, nothing intensive. I wouldn't use it for emulators, ect.
Q: Do you need PRL/Profile/Radio updates? Do you need to go back to sense based to do these still?
A: No you don't have to go back to sense to do these and you don't have to do these because Rom's will come with what you need. None the less if you would like to update your radios here is a thread by "Calkulin" where he keeps the latest radios updated: [ Radios ][ 9-5 ] All EVO Radio, WiMAX, PRI, NV & HBoot versions
Q: Does HDMI mirroring work on these roms?
A: As of this moment Miui and CM7 both have HDMI mirroring working, and sense all the other ones are cm7 with some tweaks they as well have HDMI working however from what i have read the only one that has not had problems with HDMI is Decks Gingerbread Rom
Q: Are all other major features (4G (except for Miui), bluetooth, front & rear camera, GPS, apps such as Netflix, Skype, Google Voice, Sprint Visual voicemail) all working at least as well as on a Sense or stock ROM?
A: Yes everything is working, however on CM7 and i presume on some others you also have to flash a gps fix which you can get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration. and the Voicemail seems to have some issues for some people but works flawlessly on Decks with it's gapps + Voicemail which you may also get from this thread: [GUIDE||Oct/23]Best AOSP(CM7|Decks|MIUI) configuration.
Q:My wifi is connecting/disconnecting after a second, what should i do?
A: This answer was given to me by "teh roxxorz." This has nothing to do with your rom or kernel, do this:
Back up everything into Titanium Backup
Boot into recovery
wipe cache, Dalvik, and pretty much everything
reflash your rom,kernel and gapps (or if you would like to check out some other roms and kernels just click on the link in my sig)
once you've set up your phone download Titanium Backup from the market
in titanium backup restore all your apps ONLY!!! (don't get apps w/ data - only get apps, and do not get system data)
after this your wifi should be working just fine
Q: I am having wake issues?
A: Here is a Guide made by JBabey[FIX] Wake Issue (Android OS) - Combination of Radio/PRI/NV/Wimax/GPS !Solved!
Q: Can i make my 3g speed faster?
A: Yes, This answer was given to me by teh roxxorz:
You need to flash a sprint sense rom. I emphasize sprint because it won't work on the sense 3.5 roms, as they're all ports of other non sprint roms.
1. Flash sense rom
2. Obtain your msl, download msl reader from market, use it, write it down
3. type in ##3282# , input your msl (you can get this from the app msl reader)
4. Click edit mode > advanced
5. Scroll down to HHTD proxy port and address
6. Change the proxy port to 0 and proxychange the address to 0.0.0.
Q: How can I fix my GPS?
A: This answer was given to me by teh roxxorz:
- flash a sense rom
- open up the dialer
- Type ##GPSCLRX# or ##4772579#
- Your enter your MSL at the prompt
- Your phone will soon reboot > done
Q: Is there a guide like this but for sense roms?
A: Yes if you are looking for a sense guide rather than aosp then check out this thread by tropicalbrit
Q: What is your setup at the moment?
A: Rom - Decks 4.0.3 Pre-Alpha 7 ICS Rom
Kernel - Stock
Governor - Conservative
CPU Max/Min Frequency - 729/128
IncrediControl (app) - (-100) [I get to (-100) by first doing (-75) and leaving it there for 3 days and then I do another (-25)]

And any reason you were gona message me?

Hi,
Thanks for guide... I am considering changing from
my stock rooted ROM, so very timely for me!
Some features that you don't mention or summarize
that may help me and others.
PRL/Profile/Radio updates? I believe you need to
go back to sense based to do these still? [yuk]
HDMI mirroring?
Are all other major features (4G (except for Miui),
bluetooth, front & rear camera, GPS, apps such as
Netflix, Skype, Google Voice, Sprint Visual voicemail)
all working at least as well as on a Sense or stock ROM?
Thanks in Advance,

Faster ICS performance on any ROM

I noticed this juts few days ago and did this on all my family's Nexus S.
Install Chainfire3d
from the market and then open the app and tap to install the driver. I used the normal method not the advanced. Don't set any other settings after your phone reboots. You can if you want to but a lot of aps won't work with those settings.
What this app does is it installs an intermediate open GL driver between the apps and phone GPU driver to give you better performance.
Just figured I'll share it with everyone. It really made a difference for me on ICS speed. The way I see it it should be baked it to all ICS ROMs.
isnt this just used for games?
that's why its called chainfire3D
the whole point is to trick proprietary games "apps" into thinking you have GPU that you don't
so you are able to play tegra adreno..ect games on other devices
dont think its works on anything other than games so i don't se how its helping make overall ICS faster.
ICS is already using our sgx540 just fine
Well, it does and it makes a difference. Try it and see for your self. Chainfire3d is not just for games.
Thank you for pointing out this tweak. I too was under the impression that chainfire was just for games.
Both tapatalk and the browser feel much smoother.
Thanks

As advertised. Nice find obsanity, it does make things noticeably smoother on general.
Noticed speed improvements thank you man

Chainfire dev recommends disabling all driver settings unless being used by a specific applications, per his xda thread:
" I strongly advise that when you are NOT using Chainfire3D for something specific, you disable all the options. This is better for system performance."
Anyone know why? Is he talking about the non-default options?
I don't know exactly, but it seems like it is just to do with the specific settings (inside the default settings section). Using the driver is fine, but any of the options being ticked has the ability to make some applications go awry depending on the device. Those options, i assume, are only meant to be used when you want to use a specific app that requires or benefits from them.
Also, i've noticed great improvements in ES File Explorer scrolling. It would lag a fair bit scrolling through long folders, but now it's nice and smooth.

That's what I was thinking as well. Thanks.
I'm installing this now... Have you guys noticed any decline in battery life?
Hopefully not :3
Does anyone know if this has the same downside as forcing gpu acceleration in the developer setting? I remember reading the Googler's post on G+ on how it increased the memory overhead by 8mb per app, reducing the memory available for other apps and processes.
Sent from my Nexus S using Tapatalk
It doesn't force GPU rendering. Alot of the Android UI is already using GPU rendering, using this intermediate driver just somehow makes it more fluid.
Trying it now, though I don't notice much improvements in scrolling.
I use force GPU setting on my phone. With the live OC in Matr1x at 111% (max my phone can handle) it does make a bit of difference in UI. But this Chainfire3D driver makes the most difference for me.
Also, in case you are on a ROM which doesn't let you change min memory settings, I'm using MinFreeManager which is a small app that just does that. The default settings which it comes built in are for GB but you can just change them manually. I don't touch the top 3 and just tweak the bottom 3. I'm currently on:
14,19,24,32,64,128
Does it effect battery drain?
Will this eat more battery juice?
Highly doubt it, and so far havn't noticed anything particularly different on my end. You can uninstall it anyway if it does cause trouble (though might be wise to perform a nandroid backup while initially installing).
Thx man, now trying it!!

Tips to increase performance and increase battery life |Xperia X8/W8

Hey people, this is my first post.
So basically this post is for people still using xperia x8 / w8.
TIPS to increase performance :
1. Install a custom ROM (with a custom kernel). It's no use installing a ROM on stock kernel because it's not very fast and battery life is low too ( I like Minicm7 and Minicm10)
2. After installing the kernel and rom, install a nice launcher. (LauncherPro for gingerbread and nova /apex for ice cream sandwich or jelly bean).
3. Tweak cyanogenmod performance settings : increase vm heap size, allow purging of assets, disable surface dithering, set cpu governor to smartassv2. Overclock if you want but not too much.
4. Use v6 supercharger script. (easy to follow and works great). Do it only if you have custom kernel, because on stock it asks to update busybox which soft bricks the phone).
5. Use autostart manager to remove unnecessary apps from boot.
6. Install apps that you need.
7. Enable "long press to kill apps" in development and kill after you use them like browsers etc.
8. Don't use task killer.
Battery life tips (I assume you are on custom ROM with custom kernel) :
1. Use setcpu and enable profiles. Make the following
A) Screen off - Set Minimum and maximum values of clock the lowest.
B) Battery levels - Choose the maximum to any value below 600 mhz but above 320 when say, the level is less than 40 percent or maximum 480 when the level drops below 50 percent.
2. Make sure you uninstall Dsp manager with titanium backup or root uninstaller.
It sucks lots of battery.
3. Don't set auto brightness.
4. Keep vm heap size to 32.
5. Set governor to on-demand using set cpu for all profiles. AS WELL as for normal usage. (where there are sliders)
6. You may use antutu battery saver. It may or may not work for you.
7. Use v6 supercharger script.
That's it. Press thanks if I helped.

Sir, Thank you for your review and the beer Yes I am aware of the fact that many people know about it but are tired going through many threads so I compiled a list. That's all.
Exactly this thread will be helpful for noobs much. Nice info :thumbup:
Sent from my XPERIA X8 using Tapatalk 2
@op you may want to review some info. for example, for performance, smartassv2 isn't really the best choice (interactive or ondemand, anyone?). you may also want to remove v6 supercharger since noobs will ultimately ask a lot of questions about it (specially ics/jb users). conversely, ondemand is NOT the best choice if you want to save battery. it has a hair trigger that jumps to max freq and stays there for a long time (like interactive but with different conditions for scaling iirc). there are also lighter launchers than nove/apex/launcherpro. uninstalling or freezing unused apps can also help performance instead of trying to kill them (specially with apps that simply restart themselves). you also have the undervolt option. and updating busybox will not necessarily cause issues if you're on custom kernel. i've updated mine on cm7&10 without issues. i do think gdx (at least on stock kernel) bootloops if you update it. as daggre said, we already have lots of tuts about this, so it would be best to give accurate info or else it will just confuse users.

@op you may want to review some info. for example, for performance, smartassv2 isn't really the best choice (interactive or ondemand, anyone?). you may also want to remove v6 supercharger since noobs will ultimately ask a lot of questions about it (specially ics/jb users). conversely, ondemand is NOT the best choice if you want to save battery. it has a hair trigger that jumps to max freq and stays there for a long time (like interactive but with different conditions for scaling iirc). there are also lighter launchers than nove/apex/launcherpro. uninstalling or freezing unused apps can also help performance instead of trying to kill them (specially with apps that simply restart themselves). you also have the undervolt option. and updating busybox will not necessarily cause issues if you're on custom kernel. i've updated mine on cm7&10 without issues. i do think gdx (at least on stock kernel) bootloops if you update it. as daggre said, we already have lots of tuts about this, so it would be best to give accurate info or else it will just confuse users.

Sorry for the mistakes. I wrote smartass v2 because interactive sucks too much battery and isn't practical to use. I would like to delete the thread. I'm new here so please tell me how. I will update the facts and then write

you'll have to ask a mod to delete the thread. why not just update it though? it's a good thread for new guys. just update some info and you're good to go.

Alright, I'll update by Monday. Thanks
Haha, thanks for the tips :good:

[Q] KTManta vs. Franco vs. Trinity

Hey guys,
I wanted to get everyone's feedback and experiences between the 3 kernels. I realize that every device behaves differently, but was curious about which ones people have tried, if they found any cool things about specific ones they really liked Or if you wanted to share your experience about the latest build.
Thanks!
Trinity and franco are about the same, but trinity>franco.
KTmanta is in a totally different league, it offers total customization and imo is the best kernel just because of that.
Franco and Trinity are all about performance where ktmanta is about battery optimizations and customizations.
I haven't used Franco or trinity in a while, I know they score higher in benchmarks if that means anything at all.

I think everyone knows my preference, but they are all good kernels. Unfortunately this tablet is not on Franco's priority list and does not see much development. I dont believe it has a 4.3 compatible version yet and the last release has a serious bug that causes SoD for most people.
I like Trinity and KManta for different reasons (those stated above). If I need to squeeze out battery life, I go with KManta and tweak the settings accordingly. But for my day-to-day use, I like Trinity for its smoothness. Just my two cents
Awesome input guys! Real useful information.
How would you guys describe KTManta when just using the stock values? When you guys say "customization", do you guys mean the voltage settings and stuff like that? I've been flashing for years, but have never really understood how that worked. Which is funny, because I am an experienced PC overclocker. People say the concept is very similar. If KTManta's customization options were removed, would it be then comparable to Trinity? Or would it still be better without all the options?
Would you guys say Trinity still has decent battery life? Compared to KTManta at stock values?
Which one does Chrome work the best with?
Thanks!
Stock for stock Trinity is better because Morfic hardcodes overclock and undervolt values into the kernel and sets up all that stuff as his stock settings for the kernel. KTManta allows you to do those things and WAY more, but does not set them up as stock values because Ktoonsez prefers to keep the default settings for his kernel closer to the default settings of the stock AOSP kernel. So while Trinity may have -50mv undervolt to everything and a GPU overclock of 620MHz (I think that is the speed?), KTManta allows you to go +/- 200 mv to any frequency step for CPU or GPU that you feel like and also allows OC to 2.1GHz on CPU and 720MHz on the GPU if you want to, as well as RAM OC if you want to, and control of the scaling of every part of the chipset, again if you *want* to. But it doesnt set any custom stuff as default since everyone's device is unique and people want to do different things with it. That is why we have pre-made settings available from various users so that you can load custom values to try out without having to go through a bunch of experimentation yourself.
