[KERNEL][CM7][Froyo] Dalingrin's OC kernel w/fixed IO perf (quadrant) & 1.2Ghz test
Disclaimer: As always, flash at your own risk.
Background
So, recently there has been alot of debate over why quadrant (and to some extent, system performance) was lower with the OC kernel, as compared to the stock CM7 kernel. (http://forum.xda-developers.com/showthread.php?t=1002504) As part of my examining the problem, i went looking for a solution. Starting from the first OC CM7 kernel, i would run quadrant and see how the performance fared. I finally found the issue appeared in the 3-08a kernel; using that, i rolled back changes until i found the commit remove to fix the issue. Specifically, it seems to be somewhere in the 2.6.29.6 update: https://github.com/dalingrin/nook_kernel/commits/gingerbread-exp
In short, using his source, i have compiled a kernel with fixed I/O performance, and all his other tweaks (interactive gov, etc).
So, I want to make this clear; this is still dalingrin's kernel; in no way do i wish to take credit for his work. But, while he is out, work must go on, right?
Information
Who is this kernel for?
eMMC Froyo and CM7 users
Will this work on SD cards?
It may if you manually replace you uImage, but i cannot guarantee it (since i cannot test it)
Is everything working in this release?
everything like bluetooth and dsp should still be just fine (you may have to do a few hard shutdowns/reboots to kick on BT, like normal).
Kernel Links -3/25/10
OC kernels (up to 1100Mhz, Interactive gov, BT and DSP):
Regular

Extra network features (PPP, etc)
http://www.mediafire.com/?i9h76wn483tk16v
OC kernel (up to 1190Mhz, Interactive gov, BT and DSP):
http://www.mediafire.com/?v6d2jpzaynvchde
For those having problems setting this speed in the CM7 performance settings, give setCPU a try, but don't use profiles. Using set CPU, i am able to get my system stable at 1190, where the CM7 manager instantly locks up.
Feedback
After flashing, please make note of OVERALL system response. The dip in quadrant scores prompted the fix, but i feel that the system is overall better; I would like some more input if others are seeing this as well.
Any and all feedback is welcome, and I will do what i can for support...
Great job man, you and dalingrin both!
Ran 3 quadrant tests on newest nightly (#30)
1. 1856
2. 1700 even
3. Whopping 2030!
Can you be more specific about which network features are in the second choice ?
Thanks !!

Um....truth is, i am really not too familiar with it, but looking a the diff between the two configs:
# Core Netfilter Configuration
# IP: Netfilter Configuration
# CONFIG_TUN
# CONFIG_PPP
I am trying out the net kernel again, to see if it is better than the last time i tried it..
Edit: Its looking better than the last time i tried it. Launcher pro hangs for a but on startup, but so far so good after that.
Just started using CM7 last night (w/bottom keys mod, so the nightly is from a few revisions back), but just installed this kernel (the regular version, w/out the Net adds, which I don't need), wiped cache & Dalvik, rebooted, set OC to 1100 and "performance" in CyangenMod Settings and now getting 1918 Quad score...vs. 1372 on the stock kernel with no OC.
I can definitely live with that score...great work to you and dalingrin!!
Thanks for taking care of this while I am gone. Much appreciated.
The update to *.6 is not necessary anyway.
When I get back I will revert the *.6 update and compile some of the netfilter/iptables and tun as modules as this seems to be more compatible than compiling them directly into the kernel.
Madcat, kudos to you. This is perceptibly faster.
great work!
so is this a 2.6.29.5 kernel then?
WOW, scrolling through XDA forum is much smoother than it used to be.
Tried on SDcard, installed by copying uImage to Boot. Reboots to EMMC when trying to load desktop. Back to CM7 stock. I guess I'll wait. Thanks though!

Can I have the config file for the first? I'm going to play with the kernel a bit.
EDIT: I'm just going to keep my big mouth shut for a while. I hoped it was just a bug with quadrant, but I flashed your kernel just now. There is a huge difference in interactivity. I was playing with the app drawer yesterday and couldn't get it to be smooth with "labels fade in" turned on and a 1000ms or so time on the animation for the app drawer. Now it's perfect every time.
GOOD JOB!
I love Open Source.
Will try this in some minutes. (Nook charging)
Ok, tested it. My scores below.
** QUADRANT SCORES **
Before update, 1100mhz: ~700
After update, 800mhz: ~1500
Now, 1100mhz: 1920
**********************
Awesome!
Just flashed it on mine and seems silky smooth to me. Not real sure there is a big difference, but it is not worse at least. Seems better to me.. Good job Madcat!!
Waiting anxiously for Dalingrin to return to his lab and see what else he can whip up for us..
nice!
i'm getting the same numbers as others (~1800) now. haven't really tested for overall smoothness yet.
will this kernel ever get a nookie version?

I have to admit - i said CM7 only, since that is all i have to test it on. If you do want to try it, you don't really risk anything; if it doesn't work, simply reboot to recovery and flash your last working kernel again.
As it is, i haven't really given a good look at what might be different between versions, so i can't give much advice on why it would/wouldn't work on Froyo.

Got the same issue with the Net feature kernel. However the other one works fine. Got 1918 Quadrant on SD Card with OC 1100 GHz + interactive gov.
So I guess CM7 performance on SD is not too bad compared to eMMC
@Divine_Madcat : Could you look into the problem of the Net features kernel with SD Card booting? It run into eMMC after the bootanimation.
Thanks much for your work, an action is much better than thousand words !!
I tried both of these from SD card. The non-net features version boots but posted some terrible #s for me (<700 Quadrant and ~6-7 Linpack); the net features version doesn't boot. Is there something special I need to do with the first kernel to see the benefits? I checked and was clocked to 1.1GHz in CM settings.

hmmmm.. that doesn't sound right at all. May i ask which nightly you are using? Right now, i am on nightly 27, and haven't seen anything like that (in my case, it either works, or just boot loops, if i set the clock too high).

TEAM n0ob FIRST RELEASE!
Ok after my OverClock How-To, I decided to play with overclocking and see what exactly can be gained from stock Max regulator Voltage (1.3v). I have found that at stock you can get up to around 1.13ghz. It is slightly faster than what pershoots kernel runs (38400khz).
As persiansown says, the standard stock voltage is set to 1275, and the regulator is maxed at 1.3v.
What Kind of gains will you see?
You will notice a difference in games like Asphalt, that use a lot processor. You will notice a decrease in battery life as well. Your linpack scores will vary from about 8.5-9.5 depending on your chip.
I have included pershoots undervolting, 21MB ramhack, and audio hack as well. Several optimizations, following in the footsteps of the Ivan/intersectRaven Kernels. (You could say we KANGED pershoot and just added two frequencies above his)
The frequencies in the kernel from 1113300-1152000 are at stock voltage(1.3v), and I have included the relevant source files. As such they "should" be safe. You never know though! The frequencies below this are Undervolted down to .925v!
This is using SLUB allocator and Deadline IO scheduler.
The recommendation of Team n0ob, is to use set CPU to set your phone to a frequency below 1.11ghz unless you need the extra power for something. Otherwise your battery life will suck and you will stress your processor for no reason.
This is confirmed working on CM-5.0.6-N1.
WARNING!!! THE LONG TERM EFFECTS OF OVERCLOCKING YOUR PROCESSOR CAN INCLUDE:
1. SHORTENED PROCESSOR LIFE
2. OVERHEATING
3. REDUCED BATTERY LIFE
4. BRICKED (IE DEAD DEVICES)
Mod edit: removed link, till source is link to kernel.
I ask that if you notice anything funny that you flash to a more tested kernel and notify this board immediately. This kernel is at stock voltage, but the increased speeds could have adverse effects. Please let us know if you notice any.
Team n0ob takes no responsibility for any damage that may occur to your device.
Credits: pershoot( thanks for the hard work), Kmobs (same), intersectRaven, Ivan (for beginning optimization trend), Rotohammer(experimental random/music/start fix), Cyanogen for awesome roms (whose source this is pulled from), chris soyars, and coolbho3000, Koush for the anykernel updater.
Team n0ob Testers: jlevey, DAMNiaTX Hell! (Thanks)
Following pershoot, I recompiled the Kernel with VFPv3 Optimizations.
resync to 2.6.33.3, old wifi drivers as everyone has problems with the new ones.
Lowered minV to 925. maxV is still 1.3. Voltages are increased to 1.3 only on the 2 frequencies above pershoots 1.113ghz. The other frequencies are undervolted similar to the Kmobs and or the Pershoot values.
Well, by "lowering processor life", how exactly long will my processor last? Does it depend on my phone? My uses? Im all in it for overclocking, and im very aware of said risk.. But processor life I'm not educated in..

Not drastic. Not concrete figures but I've heard figures like instead of something like maybe 6 years, you may get 4-5 years. The processors are designed to last so long that even things that harm them typically still leave them outlasting the upgrade cycle of the user. It depends on the silicon in your phone as well.
Also, Gr8Gorrilla, does this include CM's latest commits from a day or two ago that fixes the pink cam tint issue?
No telling really. It shouldn't be much different than stock. However, as soon as I say that someone will install this brick the phone and blame me. So I am using it and I have a two year contract with T-mobile, I figure it should make it that far.
This is basically pershoots kernel plus 38400 khz. (pershoot in no way endorses this kernel). Take that for what it is worth. The top three voltages 1113, 1132, & 1152, are at stock voltage (1.3v).
I resynced my repo last night before compiling this.
Damn nice kernel is all I have to say

Ok thanks! Definitely flashing this now!
Stock voltage is actually 1.275v. The processor is, however, rated to handle 1.3v (it was originally going to ship at 1.3v, but qualcomm decided to have it ship at 1.275v instead)

I stand corrected. I should have said stock max regulator voltage. I will update the OP.
thanks Gr8gorilla
I'm definitely gonna try this out. I've been using intersect's and ivan's, just jumping back and forth. Good to see that there's another kernel out there to play with. Thanks Team n0ob!

Yes that is correct.
Nexus FireBall 1.15GHz.
I will be also flashing this kernel update to 1.15 GHz tonight. I want to try and optimize my nexus one to its fully potential capabilities. : )
Updated, Changed Kernel optimizations. Since this kernel follows pershoot, he recommends if you are on 5.0.6 to flash the VFPv3 optimized version.
VFP works great
Hi guys when i unzip their 4 files i know the ko and zimage but the other 2 files do i need to install them too?? and how? thanx in advance.
The other two files are the source files. They there so you can research what changes I have made in the voltage and frequencies and also you could compile this on your own if you want.
Title says a helluva lot ;-)
READ THIS WHOLE POST AND THE WHOLE POST AFTER IT!
Features:
All steps undervolted about 25%. Should be stable still
The table is currently 300, 600, 950mhz until I can make it scale more than 3 steps.
The voltage for 950Mhz is less than at stock for 800Mhz, so you should see better battery life even though we're overclocked.
Display flicker fixed (or at least toned down, it can't be completely eliminated with the LED backlighting)
Scheduler tweaks backported from later kernel versions
Some governor tweaks of my own for responsiveness
To install this, just flash the zip in ClockworkMod. This shouldn't harm your device, but I make no promises. I trust it enough to run it on my device, if that means anything to y'all. I also attached a zip to flash back to the stock kernel (..but why would you break my heart by doing so..? ;P).
Next Up:
I REALLY want to get 1Ghz+ working, and my code is sound (I'm sure of that) but it won't boot on my device. I think I just need to find the right voltage, or I could have a bad die for OC'ing. This is the first thing I will work on.
Maybe the interactive CPU governor
Look into the 2-point touch limitation

Changelog:
1-11-11 - Screamer:
Overclock to 950Mhz. Still chokes at 1Ghz, which tells me it's probably my device. 950 is stable.
Temp sensor drivers. Thanks to the Nookie FroYo guys!
Updated to 2.6.29.6.
Scheduling tweaks from 2.6.31.
Code idle time from 2.6.34.
Scaling fixed. Now scales properly between all 3 CPU levels. Adding more than 3 makes it choke for some reason. I'll look into it.
Test version set at 1Ghz added. Just because it doesn't work for me doesn't mean it won't work for you. Don't get your hopes up though, I've tried making it work every way from Sunday
Notes:
Screen WILL be unresponsive immediately after a boot. Just lock the device for several seconds, unlock it, and all will be fine until another reboot. I blame B&N, it happens with all custom kernels.
Yes, I know there are more versions of this kernel than there are Windows Vista. The middle one is the recommended one. If your Nook can't run at 950Mhz (crashing often, or just won't boot) try the one with the 900mhz tag. If you wanna try and push it higher, try the 1Ghz one. Be warned: very little success is reported with the 1Ghz kernel. The top level of these chips seems to be right around ~925-975Mhz. Very few devices will be able to hit 1Ghz.
You should probably wipe your cache partition after flashing this. You won't lose anything, and many people are reporting that it makes things more stable at the higher freqs for them.

Wow thanks so much for this. Gotta try it out!
wow very nice! going to have to give this a shot!
Awesome! But is it compatible with nookie froyo (2.2) or the stock BN (2.1)?
Update: It boots Nookie Froyo but powers off immediately after booting. I am looking forward to the release of the 2.6.32 version of your work. Keep up the good work!

Just stock 2.1.
With the Nookie FroYo, it wouldn't flash the kernel to the SD for boot, plus (at least on th Epic) a 2.6.29 kernel won't boot on FroYo, it needs 2.6.32 or higher
Glad to have you part of the nook color family. You did awesome work on the Epic4G.
Looking forward to more great stuff from you.

Loss of touch sensitivity
I loaded up the new kernel via Clockwork and all went smoothly with the install. I noticed immediately that my touch sensitivity has decreased. I now have to press and hold just about as long as you would press and hold to bring up a context menu or something. If I don't do that, my touch is ignored and not registered.
Interestingly enough, when I type an email on the keyboard, it recognizes my typing very quickly. No apparent loss of sensitivity when I'm using the keyboard. I wonder why and how that is???
I guess I need to recalibrate the screen again to regain sensitivity.
I did notice that Castle Crashers frame-rate has improved a good bit with the overclock. It's a noticeable and welcome difference.
Angry birds was a bit annoying to play with the loss of screen sensitivity.
Edit: I alleviated the loss of touch sensitivity by installing the LCDDensity app from the Android Marketplace and selecting a density of 200.
Tried to install via clockwork and I keep getting errors unable to install. an I missing something?

Got it working with clockwork update... thanks!
Flashed. Am loving it, seems much snappier, and the keyboard response at 900mhzz is much improved. Keep up the good work!
NC overcklock
Hi,
Last month I made some tests with overcloking /undervolting. I was able to push the NC at 1.15GHz, with a little voltage tweaking. 1Ghz was achieved without voltage tuning. The smartreflex technology adjusts automaticaly the OPP voltages to minimize the power consumption. Maybe the L3 speed can be increased to 200 Mhz by setting DPLL at 400MHz (in u-boot).

me too, seems touch for a while(XXms) take effect, less then that screen acts like nothing touch it. this drived me mad when using Gellery, switch pictures give terrible feeling.
i think this relay to the clock scaling, i will check this out using SetCPU.
thanks for your work!
Amazing work with the kernal. I flashed and changed density to 200 in Root Explorer /system/build.prop and it works great.
Also in Spare parts I change both animations to Fast instead of defaults.

Can you add me in GTalk? [email protected]
I have some stuff I'd like to ask about. How did you do the OC? Did you change the actual clock in u-boot so everything scales up? Or did you add more VDD_OPP* steps. I used some of the code I saw before for the Droid's 3430 chipset, using the OPP steps. The stock kernel has steps built in for up to 1.2Ghz, but if I enable them I can't make it boot, at least on my device.
I can't figure out the voltages either, probably because I fail at hex. If I understood that, it would help me a lot.

Hrrm. It sounds like the CPU scaling is staying low, because I see absolutely no change in the touch sensitivity, and I didn't touch any of the code related to it. Try setting the CPU Governor to OnDemand or Performance in SetCPU if it isn't set there already.

Odd. That's exactly what I've done (with a couple diff voltages) but it won't boot on my Nook. I guess I just got a bad die. Can you explain the voltage values? I know how to increase/decrease the hex number, but how does it correlate to the actual voltage? Like how is 0x38 = 1.35V in a stock kernel?
Definitely going to try this out. Thanks for the work. I'll report back with comments/questions/concerns.

This kernel has been around for the Inc and the Evo. Now I'm bringing it to the N1 and the Desire!!
Great stuff, always nice to have more kernel choices
MOD : Can you post only Nexus One kernel on your post please (more readable)
Had been having some wifi issues this past week using cm7 nightly along with various kernels. Wifi was frequently dropping or just very slow. Spent most of Sunday screwing with my home network which seems stable now. I think comcast must have been doing something. however, my phone wifi was still poor. installed this kernel last night and so far phone is performing as it should on wifi. the difference was immediate. not sure whats going on. cant comment on battery life yet, but it's looking very good through this mornings use. Thank you!

I'm glad it's working for you, but that is strange... The only change I make to wifi from CM is undervolting it. And now that I think about it, I may have forgotten to bring that tweak over to the n1 and desire...
Can you summarize how your kernel differs from the others (CM, pershoot, wildmonks, redstar).

Versus the main CM kernel, this has unrestricted overclocking, HAVS, smartass, undervotling, sysfs interface and several other tweaks/improvements. I don't have a N1 and honestly dont know anything about the other kernels out there for it. The kernel started on the Inc and Evo, mostly around MIUI, and I was asked by a few people to bring it over to the N1 and Desire, so I figured I would post it up for everyone.
Hi all,
Been running this since 0800 this morning (its now 1800) no problems at all.
Can't say its faster or better on the battery for sure but its certainly no worse than CM stock.
Whats the smartass govenor? Just the same as on demand as it seems to replace it?
Oh, just one thing, although it has the option (in SetCPU) to go down to 128mhz, I've not seen it go lower than 245mhz which makes me wonder if its clocking down to 128 with the screen off.
Anyone else?

The on demand governor was removed to force the default to smartass (the default is usually set to on demand by the ramdisk and is not affected by setting the default in the kenrel), but the two are not similar. Smartass was built off the interactive governor.
As for the 128Mhz floor - that is something finicky about the smartass governor. It should drop to 128 on any other governor though.
Smartass Governor shows real potential...thanks for this!
what about the wonk?
From what I gather the wonk is due to something in CM7 kernel. I also noticed that it is absent from stock 2.3.3 and also absent from AOSP builds.
Has anyone tried CM7 with this kernel?
thanks for the N1 kernel.
I'll try ASAP.
I will try this kernel now, thanks for posting. New kernel cooks are always welcomed.
After about 18 hrs on this kernel, the results are pleasing.
Extremely stable on the Smartass Governor, which is surprising because I've had friends compile me kernels incorporating this governor, and the end result = unusable.
Battery life seems fantastic so far.
Clocked 128-998. No profiles.
Thank you again for this kernel.
Results on N1
I have been running this kernel for 24hrs at 128/1228 and it's been running great with smartass selected on my AT&T N1. I tried going even higher than 1228 but that causes it to crash immediately (I'm surprised it can even handle 1228.) Linpack is a little low at 23 compared to other kernels that can get up to 40. Quadrant also comes up behind at only 1051.
tried going at the highest setting & it crashed my N1 , BACK TO RESDTAR'S kernel .
Been using the kernel for a few hours, Kernel seems stable but definatly doesnt feel snappy.

I would like to thank all the testers who were brave enough to flash my kernel. Please be advised that I do not own any Transformer device (well I used to own a TF101 before it's ICS days till my boys ended its life early) and so I relied heavily on the testers. Please click on the DONATE TO ME button if you appreciate my work.
BIG THANKS to my wife for allowing me to do this work Big thanks to all the testers too. Thanks to the donation of Blackwidowman (first donation), shaolin95, Stuart P, Jack S it's greatly appreciated
A Backup is a must and you should be knowledgable on Restoring your device, NVflash knowledge is recommended.

I would love to test this if for JB. PM me o know! I have been trying all the JB builds trying to get the most stable in the KB dock and have all features enabled. Even the best seems to randomly reboot every now and then. Its still fun to mess with all the options and builds!

Hello corey113888! Have you tried the new Baked JB that Craig put out yesterday? I installed and set lock delay in settings to 15 seconds after screen blank and so far I have not had a reboot in the dock!

Cool. I am installing that one now. I guess TWRP does not support mounting micro SD card formatted NTFS. I cant seem to get recovery to see it. Otherwise I would be rocking it already. I use a wireless mouse to. It has a USB receiver and I did not know if it might be causing the reboots.

We got it to boot in Androwook and ClearROM This kernel is not based on _motley but on asus 10.4.4.18 which is JB. I also built one for CM10.

I also have a wireless mouse with the usb receiver. That plus an sd card in my dock. I've tried taking everything out of dock and still would get sod's and reboots. In my case it always happens when the screen times out. In the baked settings you can delay the lock for a settable amount of time and since I delayed the lock, I've not had a problem!
cool, where do I download the kernel?

I didn't download any special kernel. Just using what was in the rom. I did flash the tweaks and disabled journaling.
The Prime really takes off with this, I have both a Infinity and a Prime and the Prime handles graphics MUCH better due to the higher
screen resolution of the Infinity. Thanks for this, almost like a new device.
I will figure out how to pull dmesg to post. But I don't think I ever tried to overclock that high. Regardless, I'll donate when you post a working kernel. I'm very excited for a new kernel for this device. I think we could really use it. Thank you.
Update:
1. Some testers able to boot with my 1.8ghz 650gpu on stock ROM and kernel modified for stock ROM, some can't boot. Some are unstable at 1.8ghz
2. Same as above CM10 rom with CM10 kernel but wifi is not working at all
Beta kernel released
Will be trying this on Androwook 1.3. My Prime already flies with the Cleankernel but 1.8gh is irresistible. Will post back with how it goes.
EDIT: Flashed fine. Unstable running benchmarks at max OC and is now bootlooping.

I tested kernel and it booted fine but resets when running bench marks. Also i tried down clocking it to 1.4 or 1.5 but even though i have it set to top out at those speeds it was still running up to 1.8 and running at top speed(1.8) the tablet began running real warm so i restored my backup to flash my previous kernel so i dont dmg my device before you get this all worked out for us.
Running this on hairy bean 1.3 in the KB dock and all is well so far.
Can we get SIO scheduler? or an i compile one and add it

Same here. Runs smooth until some heavy CPU stuff is going on, then reset. I guess, my Prime isn't up for 1,8GHz, but I really like the overall performance of that kernel. Any chance to restrict the maximum frequency to 1,7 or 1,6GHz?
Regards,
Kashban
I used the clymsyn-blades kernel for the longest time on my TF101 before I traded it in for my prime. Definitely going to be using this one.
Question though, do the battery saver/medium performance/high performance buttons work with this kernel?
I tried to give this a whirl, but as I suspected, it overwrote my data2sd installation (so I restored my nandroid)...
Anyone knowledgeable able to merge the two together?
I just installed with with Androwook 1.3 JB and Quadrant is reporting max speed as 1300Mhz only and I cannot get it to go even past 1.2Ghz no matter what mode I try.
Anyone else having this problem?
Are the engery options still working with your kernel? I dont want to run it @1800 all the time...
Boots at 1800 but system tuner or something puts it to 1400. then I had random reboots and went back to clean kernel.
What file controls the GPU speed?
This is loosely based on CTXz's kernel. I just wanted a little more from it. I'm using it on my "Nook". Hence the name.
So may I present to you.....
Nuki - Kernel
Install:
Just flash this through TWRP recovery. I use 2.8.7.0. It'll do it's own wipes.
It's built for the "Nook" version. But should work for any WiFi only ROM.
My preferred tuner for the kernel is Kernel Audiutor . But others should work also.

Mine! Will post feedcack! :fingers-crossed:
@engine95 - awesome. Gonna test it out and let you know
Looking good. Confirm working looking the SM-T230NU......should work on SM-T230 as well.
Well done. I hope it works good for you all!
Just a little update.
I'm trying to work on the GPU now, and it's proving very interesting. This GC1000 GPU treats the cores as being separate. Meaning one is for 2d @ 416mhz the other is for [email protected]
It looks like our possible freq's are 533, 624, 702. And maybe one close to 800 according to the specs.
The problem I see happening, is that we'll be locked into whatever freq I build into it. Meaning there isn't a way to change it through a kernel tuner.
So far, I havent had any luck OC'ing either of them. But we'll see what happens.
V1.1 is in OP See read changelog
Still no luck with OC GPU. But theres 2 builds: Linaro and Ubertec toolchains. Let me know which one you like/prefer.
Enjoy
Nice
so what's the point?
new features?
overclocked?

I don't know you. So I don't know if this is sarcastic or not. So I'll play this answer in the middle.
Read the change log and look at the git. Almost everything here has been reworked, updated and/or added. Oc is the only thing I haven't touched. Yet.
@engine95 - for me, my tablet runs smoother on the linaro build.
Nice update and thank you.

On my past kernels, Ubertec seems to usually run faster. While Linaro runs smoother. But on this tab, it's harder to tell. So Thanks for letting me know. :good:
I am impressed with a lot of the optimizations that "Sammy" has already build into this. Source code I'm used to changing is already in it. And this thing sleeps like a baby.
It's too bad Marvell/Vivante/Sammy has throttled this CPU/GPU so much according to the specs. I mean, for a low-end setup it could be a lot better. But then, it would probably lose battery.
I'm not going to add anymore "stuffs" to it, as I think we have a good selection now. What is in it should satisfy " battery thru performance" depending on the settings people choose.
I haven't even looked a OC CPU yet. All I've tried so far is GPU and that hasn't gone well.
These will be the next things I'll work on. Unless......"SQUIRREL!"
forgive my ignorance, normally i would use the googles and xdas to educate myself before asking such a question, however, I have basically given up on this tablet.....so does your development of this kernel bring the tab 4 7" owners any close to getting an aosp build, this tablet is useless running TW?
edit: upon review, my post was thankless but i am very thankful for you doing what you do for this tablet, it so needs the attention!

Its all good. No worries.
Unfortunately, no. It just improves on stock.
Im new to Samsung, so its all a new learning curve for me. I am kinda shocked at how "low-end " this is for a mainstream tablet. I'd have thought it would be.....better.
T-230 with nuki v1.1 linaro. Working amazingly. Thank you much.
Thank you for this kernel! I've never even thought to use another kernel for this low-end device.
Mine was originally the Nook version as well but I have flashed the latest non-nook firmware and heavily modded it.
I'm using the Linaro version. Xposed is running with a few modules. tuning with Kernel Audiutor.
The device it running very well. smoother than normal. It's a bit warmer too. but we'll see about that though.
Uber variant. Makes a huge difference. Thank you!!!
Still using the linaro. I can't seem to make either of the CPU frequencies stop being max. (1344)
Any suggestions? I'll end up trying the Uber kernel in a moment.

When you reboot, you'll need to set min, manually. I don't know why.
Or, try a different gov. Lionheart and conservativex are my preference.
You may need to remove the set on boot option, then reenable it.
It shouldn't be sticking like that
Mhh, that all sounds very interesting. Possible I can test it this weekend.
CTXz kernel is my first choice all that last year, so I can test it against yours. Don't get me wrong it will be very interesting to see what's different.
Not to see what is better, I wish to see the difference. Every ROM has his specific use and modifications. So it is the science guy who wish to know it .
Will report later about it and CTXz I will be every time a fan of your work .
