Which is a decent way to do it. However, in this scenario we want to compare against other phones. Quadrant gives huge unfair advantage to phones running 2.2 because of JIT.

If I were the dev, I'd find another test and remove the ones that rely on those. Sure its fine when ALL phones are 2.2+, but sadly we haven't reached that point.
[Epic 4G Android Development] troyolson92:
Genious, are we too expect more of your magic in form of a kernal update tonight?
[Epic 4G Android Development] Geniusdog254:
Probably, theres a bug with some new brightness settings that popped up today during testing. I need to fix it real quick and make sure it's gone.

On the bright side, I ran this all day. First time I've felt *confident* in my Epic's battery life. I went 10 hrs 27 minutes until low battery and I plugged it into charge then. I could have gone another hour or 2 until it died, so things are great!
[Epic 4G Android Development] odub303:
Is it safe to assume you were engaged in moderate to heavy usage? If you enjoy this phone half as much as I do, I can't imagine using at in any other way lol.
[Epic 4G Android Development] Geniusdog254:
C'mon now, we both know there IS no other way to use this beauty than heavily ;)
[Epic 4G Android Development] odub303:
Tell me about it. I bump charge it during my drive to work, keep my old Palm Pre wall charge at work and then charge it on the way home. Fruit Ninja (the ultimate time suck - soon to be supplanted by Angry Birds when it comes out of beta), Bubble Blast and general messing around eat up my battery real quick.
[Epic 4G Android Development] troyolson92:
10 hrs wow. I went from full overnight charge to 30% in two hours this morning heavy use.

Btw I did some testing, during that time and found no quadrant score difference in having 120mb free of ram or 170mb free. It was very very interesting to learn that much ram difference made no preformance difference. Guess I can be alittle more leanant with my minifree memory app. Had it set to 150 now set to 120
[Epic 4G Android Development] Envynet:
Stop using task killers... its been proven they do more harm than good.

http://www.tested.com/news/android-task-killers-are-deadheres-what-you-should-be-doing/923/
[Epic 4G Android Development] odub303:
I believe the minifree app he is using is not a task killer but rather modifies android's settings with respect to when it kills off applications based on free memory and priority. It seems like the general consensus that this is the best way to go these days.
[Epic 4G Android Development] Coucher:
Geniusdog254,...is this Sunday night update, that became a Monday night update, becoming a Tuesday night update?

:p

Looking forward to it..
[Epic 4G Android Development] Geniusdog254:
Unfortunately yes lol. I ran this as my daily driver today and found a couple bugs that I *think* I fixed, but will test tomorrow to be sure.

Also ended up with lots of schoolwork tonight, so I didn't have as much time as I hoped.

Sorry guys, 'tis coming though! :D
[Epic 4G Android Development] troyolson92:
Thanks for advice but I use auto killer memory manager. Just like min memory manger it just allows user presets for the android system to utilize versus 'killing' apps.

After update I'm going to attempt to switch over to the ex2 and 4 file system. I'll post results and stability and speed.

Why doesn't rom manager and quick boot boot into recovery? Is the kernal that sends it to stock recovery? I have stock di9 with the mixedup voodoo kernal and clockwork.
[Epic 4G Android Development] Geniusdog254:
Nope, that is Samsung's filesystem setup. Thanks, morons :rolleyes:

They should really learn to code lol
[Epic 4G Android Development] odub303:
My Rom Manager boots into Clockwork Recovery. I have both noobnl's CWM and the official Koush CWM installed (as I understand it they install in different places in the file system). This way I can access CWM through either Rom Manager or using the volume/camera/power combo on boot.
[Epic 4G Android Development] ragnarokx:
Why do you need both? I went back to stock using Odin and only installed the official CWM and I can boot using the key combo or ROM Manager.
[Epic 4G Android Development] akijikan:
According to that article, that's only true of 2.2 and beyond.
[Epic 4G Android Development] andrewjb:
I am assuming the voodoo in this rom is tweaked for Epic. This site say's it isnt supported yet. Can I flash just the voodoo zip?
[Epic 4G Android Development] Geniusdog254:
No, download the voodoo version of the kernel. This IS NOT the lagfix. There is no need for it on the Epic since we don't use the EMMC interface for internal memory. It is just the color fix. And yes, it's ported for Epic.

Release is coming tonight. I think I fixed the brightness bug.
[Epic 4G Android Development] Xaeonis:
Are you planning on releasing the kernel for any of the other revisions? DI07 and DI18? The updates are already out, and I assume the kernels are just extracted from that?

Does your kernel not also suffer from the upload issues from the 3g? I only ask, because Im loving your kernel and havent updated to DI07 or DI18 but now with the release of the offical DI18 standalone update with odin, I see no reason to, unless, of course, your kernel isnt affected by the issues of upload (which, from what I understand, and I could be wrong, is a problem with the DG27 kernel, which mixup is based upon, right?)

If the 3g speeds are limited by the ROM, theres no reason not to update...correct?

Thanks Genius, loving things so far! :D
[Epic 4G Android Development] Geniusdog254:
If I understand what you mean, this new version is rebased to DI18 source. If the problem did lie completely in the kernel & modules & not at all in the ROM, then this will fix it when I release.
[Epic 4G Android Development] Xaeonis:
Rebased eh? Then it looks like Im wiping my phone and redoing everything rom scratch using the DI18 source and odin method, then using your kernel when its finished.

****ing amazing. Great work dude. I could not be any more pleased with your progress. Thank you so much for giving to the community like this :D
[Epic 4G Android Development] odub303:
::twitching in anticipation of updated kernel::
[Epic 4G Android Development] Geniusdog254:
Building now. I just have to zip them up and upload. Oh and get my source all together..
[Epic 4G Android Development] odub303:
hooray!!!!!! looking forward to it, love your kernels.
[Epic 4G Android Development] Geniusdog254:
Aaaannnddd it's up. Be sure to read the whole OP over as I changed a few things. Also, be sure you download the 20101005 version from today! I left up the old version for people who haven't upgraded to DI18 yet, in case the DI18 kernel causes issues for them.

I'm open to feedback! I don't think there are any bugs, but I'm probably wrong on that. Pretend its a scavenger hunt lol.
[Epic 4G Android Development] Mammon88:
Great Job!!! Can't wait..Im building my rom right now....!!!!!!

Thanks for the hard work!!!
[Epic 4G Android Development] odub303:
zomg...flashing now.....
[Epic 4G Android Development] Dameon87:
Already flashed. DEFINATELY snappier than the noobnl kernel.

Very, very nice work Genius! Running a few benchmarks now.
[Epic 4G Android Development] odub303:
Just flashed, using with AOSP Magic .3, using non OC'd specs (1 ghz max cpu) I got the following benchmark scores.....

Linpack - 9.45 mflops

Quadrant - 1016

That is bananas for a non oc'd kernel lol.

OC'd to 1.2ghz I got the following:

Linpack - 9.6 mflops

Quadrant - 1015

Is that weird or what? But who cares! I will leave it on 1ghz max and enjoy the tremendous performance!
[Epic 4G Android Development] Dameon87:
First run on Linpack = 9.684

Quadrant = 1027

Neocore = 55.6 FPS

(NOTE: This is NOT using SetCPU, and using default CPU scaling)
[Epic 4G Android Development] MysteryEmotionz:
With the updated modem and your kernal my upload speeds are stool capped
[Epic 4G Android Development] odub303:
I can confirm that I do NOT have capped upload speeds over 3g using this kernel in AOSP Magic .3
[Epic 4G Android Development] MysteryEmotionz:
I'm using the boss rom v.02
[Epic 4G Android Development] odub303:
Does this version include an updated voodoo color version? I swear the color improvement isn't just at 100% brightness.....
[Epic 4G Android Development] MysteryEmotionz:
I went outside and ran another speed test and I hit a upload of 456 so it must have been my building blocking signal on my last test
[Epic 4G Android Development] ericizzy1:
i dont know why but installed the non voodoo version, but my phone says its the voodoo version...anyone?
[Epic 4G Android Development] Vanquish46:
Does this work with the EpicExperience ROM? I don't mean to question the developer but, is it safe to overclock and reduce voltage at the same time?

Sorry for the mundane questions. This is my first android device and I'm trying to get up to speed so I can start developing myself.
[Epic 4G Android Development] icantdrawanime:
What kernel version should show up after flashing this rom? I'm getting 2.6.29

I suspect that the kernel isnt being flashed correctly...

Any ideas?
[Epic 4G Android Development] Mammon88:
You know one the thing I like most about Geniusdog254 is he gives us the source!! This is truly a great community Dev!! Keep it up Geniusdog254...Its time to find that donate link.....
[Epic 4G Android Development] icantdrawanime:
Actually, it seems like the voodoo kernel didnt work but the non-voodoo does...
[Epic 4G Android Development] hozg1121:
just downloaded and flashed onto my phone which is running Epic Experience 1.1.4 ROM and my first benchmark test was only 860??
[Epic 4G Android Development] jsanta11:
Just loaded up the non voodoo version and everything running extra smooth got it set to 1200.. am running ver 1.1.4
[Epic 4G Android Development] bubby323:
Speechless, first time personally trying out your kernal and battery life is superb. Don't even get me started about voodoo color fix, friggin amazing. Night and day diffrence.
[Epic 4G Android Development] Geniusdog254:
My bad, I just checked my ramdisk. I left it set to display Voodoo no matter what haha, my bad.

Actually, the kernel version will always say 2.6.29 (until we get 2.6.32 source from Samsung for FroYo anyway) check the Build Number box. It is what I update to show my kernel version. In this case (because of a fail on my part) they both read "SPH-D700 Mixup Kernel - DI18 - VooDoo". Anyway, if you see that it's being applied.

EDIT: Also, to the person who asked about it being safe to undervolt & overclock at once, yes. See, it isn't a static voltage for every speed. I individually set each speed step to a safe voltage. Samsung has to set it a little high just to be on the safe side that it runs on all phones. I have undervolted about 75mV on every speed step from stock, because any lower would probably lead to instability on some phones. This value is perfectly safe, and at the very worst case if you got a bad CPU for undervolting, it just freezes up and as soon as you flash a different kernel with a voltage that works for you you're safe again ;)
[Epic 4G Android Development] hozg1121:
is it good to leave set cpu at 1200 max and 100 min and no profiles like for screen off because usually when i use setcpu with a screen off profile i wake up in the morning and my phone is just a black screen and i have to do a battery pull? Please elaborate on setting up setcpu with this kernel. Thanks!!
[Epic 4G Android Development] Geniusdog254:
You don't have to use SetCPU if you don't want to, my kernel handles that. I personally keep SetCPU installed because I sometimes need to tweak things on the fly, but I never miss with profiles so I can't really give you any pointers there.
[Epic 4G Android Development] ragnarokx:
It seems like voodoo now works at all brightness levels. Awesome!
[Epic 4G Android Development] BopChie:
thanks for the update... been pateintly waiting for this since flashing to DI18
[Epic 4G Android Development] keysoh2:
I installed both voodoo and nonvoodoo it seems that the voodoo version is OC by default. I got 8.1 on the nonvoodoo and 9.7 on the voodoo version ;-)...
[Epic 4G Android Development] mattallica76:
I noticed too, but not a problem for me. Saved me some time.
[Epic 4G Android Development] Geniusdog254:
Haha **** guys I made some mistakes here. Actually, I think I mixed up the files. I just checked the voodoo version, and Voodoo isn't really there.

Alright, just checked. I think I uploaded two of the same file with a different name lol. I suck today :o

Fixes soon guys!
[Epic 4G Android Development] Mr.Muscles:
Dude you freakin rock man! I've been refreshing this page like a crack head waiting for his next fix. Your work is awesome. This Epic being my first Android device, is the pest phone I've ever had, and now with the upload problems gone and your sweet overclock kernel is the icing that makes it perfect. Question I've yet to try any roms, could someone recommend me any, I'm kind fond of touch wiz now, I've just been stock with overclock.

Sent from my f'n awesome Epic 4G
[Epic 4G Android Development] Vanquish46:
Thank you!

Also thanks for the explanation geniusdog :) it satisfied my curiosity.
[Epic 4G Android Development] 1deviant:
Uploaded the Voodoo version about 30 minutes ago...FAST! Thank you very much for all your work. Is this version the 'fixed' one ...actually has Voodoo and is there a good way to tell?

Thanks again and glad to see the troll from before has gone away...
[Epic 4G Android Development] Forcystos:
It seems kinda stupid to ask something like this, but here goes: I installed this (1005-novoodoo), removed the other root stuff (jk-su, playlogo and renamed the other, etc), but I can't use Root Explorer. What gives?

EDIT: Same with SetCPU

EDIT2: Just tried su from ConnectBot and I get permission denied. Should I install Superuser.apk?

EDIT3: Installing Superuser.apk fixed everything. Should be installed by default in this case.
[Epic 4G Android Development] Geniusdog254:
Actually I haven't uploaded the fixed one yet. I have to track down the issue.. The code is all there right, and the files are right, yet it doesn't work? I'll get an update out tomorrow. That appears to be the only bug, everything works well otherwise, just no voodoo on either kernel.
[Epic 4G Android Development] mattallica76:
Root Explorer works fine for me, but I never had the other root stuff installed.
[Epic 4G Android Development] id_twin:
This means you most likely don't have root, and you will need to re-root your device.
[Epic 4G Android Development] Geniusdog254:
Uploaded a fixed Voodoo version. Should be version mixup-20101005-1119-voodoo.zip

All is well on my end.
[Epic 4G Android Development] NYYFan325:
After flashing the new kernel version my brightness at 0% seems VERY low...

I notice every once in a while it goes back to normal for a few seconds and the second i touch the screen it goes back to being dim.

Even turning the brightness up over 0% still has odd fluctuations (it seems to dim back down without me touching anything)

This issue wasn't present in the non-voodoo version

Just a heads up...

(This is in regards to the voodoo version)
[Epic 4G Android Development] Geniusdog254:
Thats intentional. I set it slightly lower since in a totally dark room even at 0% it's still too bright for my eyes. If I get too much bad feedback I'll raise it some more, but me (and several of my testers) agreed that the default lowest brightness was still too bright.
[Epic 4G Android Development] NYYFan325:
Ahhh OK good to know. Thanks for the info.
[Epic 4G Android Development] thomasskull666:
Awesome, works flawlessly. Thanks Genuisdog i appreciate your effort!

[Epic 4G Android Development] thematrixkid17:
Brightness on low setting looks okay, but whites look a little yellow at that brightness. Probably why they didn't have it go that low to begin with.

So.... rndis is next on the list, right? :D :D :D

Comcast is doing maintnance (they broke the internets) again and I'm tired of losing connection every evening...
[Epic 4G Android Development] ZenInsight:
Man, I was wondering if my eyes were tricking me. On 0% the whole room was lit up. lol. Anyway, I haven't even flashed this yet and I just wanted to say I really appreciate dedication from guys like you. Rock on man!!
[Epic 4G Android Development] keysoh2:
using the app "Quick Settings" the lowest brightness is from 6% - 9%, then from 5% - 0% its actually brighter.

Quick settings always brought the brightness even lower than the stock lowest settings.

The voodoo version is OC by default right?
[Epic 4G Android Development] 1999TL:
HELLLLL YAH. the default lowest setting is way to bright. THANK YOU for changing that.
[Epic 4G Android Development] ZenInsight:
"Fixed root issues finally, if you experience them you still have the JoeyKrim exploit installed"

I did use one-click root from Noobln which was based on joeykrim wasn't it? Am I supposed to do something different? I am on stock DI18.
[Epic 4G Android Development] Linuxuberant:
Where are the sources for the latest version 1119?
[Epic 4G Android Development] xusxmarinesx:
So I hve clockwork and flashed the new 1119 kernal and it gets stuck at the samsung screen
[Epic 4G Android Development] drizek:
Thank you for lowering the minimum brightness. I used to not be able to use the phone at night. Hopefully this is better.
[Epic 4G Android Development] Flak:
anyway to get the lowered brightness without everything going yellow? ;)
[Epic 4G Android Development] tommi_han:
Great kernel but crash and had to pull battery when playing intense 3d games like nova and sandstorm...had to go back to non oc kernel
[Epic 4G Android Development] ZenInsight:
Ignore this post. I don't know what the warning was but I am running this kernel with no problems at all and I still have root.

[Epic 4G Android Development] Xaeonis:
Geniusdog...

I think I love you :D

Just flashed (using odin) back to DI18 tonight, ran one click root, got clockwork installed, then flashed your kernel and everything is super awesome kickass ridiculously ultra mega ****ing sweet.

Just sayin'.

Oh and expect a donation coming your way. Its up to you on whether you would prefer an app buy or a cash donation through paypal or something.

Thank you again for all of your hard work, and dedication to an open source project like this. Also, thank you for keeping this open source and providing your source to future developers. I may not know what the hell to do with it, but I know other people do, and can use it for the good of the community.

Looking forward to all of the updates I know youll have in store for us in the future (and of course, FroYo builds :D!).
[Epic 4G Android Development] phantomevo77:
Man, I am STILL having the lock up issue. I don't run SetCPU i run it like a stock kernel and I get lockups every 2-3 hours.

[Epic 4G Android Development] NYYFan325:
So one more thing in regard to the brightness with the voodoo kernel...

So you purposely made 0% lower which is cool, but after the screen timeout where it would usually get dimmer right before the screen shuts off it gets brighter instead. Is there anything I can do to change that or possibly does it need a fix?
[Epic 4G Android Development] NeonMonster:
The 0% setting is a good level, but the fact that its MUCH more yellow is visually distracting.

I also noticed that when the screen times out, the screen gets brighter than shuts off.

Likewise when the screen is woke up, it is brighter then dims to the murkey yellowish white.

posted from a EPIC4G.
[Epic 4G Android Development] dondadah88:
I see the yellow but im sooooooo happy the screen is so dim. I can now use my phone at night time. I just wish it would auto change.

It would be nice of it dim like when you press the brightness on the clock app.
[Epic 4G Android Development] phantomevo77:
Newest kernel, i still get my lockups every 2-3 hours. UGHHH SOO FRUSTRATING!
[Epic 4G Android Development] icantdrawanime:
Some SOCs wont be able to handle undervolting. Thats just an unfortunate consequence of the way processors are made. If your processor locks up its because the voltage is not enough to deliver critical signals to the right places fast enough. You'll have to go with a normal kernel. If geniusdog has time, he may upload a kernel that isnt undervolted. but for now you have to go back to stock.
[Epic 4G Android Development] cicada:
This kernel seems great, thanks Geniusdog254!

After rooting around the voodoo color project page, I decided to give it a try and I'm glad I did - perfectly fixes the blue saturation at full brightness!

I'm curious though, it seems like by default the voodoo installer wants to reformat a partition to EXT4 to fix lag issues with the rfs filesystem - after installing the kernel I don't see any ext partitions, assuming this part of voodoo wasn't included?

[edit] Ignore that, just read on the Voodoo page that Epic support hasn't been included yet for this.
[Epic 4G Android Development] tommi_han:
I think he ported the color and not the whole voodoo since epic doesn't need lag fix, afaik
[Epic 4G Android Development] joshottley:
This kernel is amazingly fast. Just flashed it a few mins ago and I can see th difference. You rock!
[Epic 4G Android Development] amdille:
Sweet!! I can haz moor battereez now!!
[Epic 4G Android Development] joshottley:
Anyone had this new one running for a while to see how the battery lasts
[Epic 4G Android Development] thematrixkid17:
Well considering it was released yesterday.... its been running so far fine for me... it seems to be better than stock
[Epic 4G Android Development] joshottley:
Yeah I litterally flashed it 30 mins ago. I definatly see a speed increase but im also hoping for improved battery life
[Epic 4G Android Development] cicada:
Installed last night of course, charged overnight until about 6:30AM, it's 11:45am and with what I'd consider pretty normal usage my battery is down to a whole 92%

I'd call that pretty great so far.
[Epic 4G Android Development] zetterwing:
Love this kernel. Awesome work! Speed and battery life combined. Now that I have a "stock" situation I love it's time to try some roms.
[Epic 4G Android Development] Geniusdog254:
Uploading my source to github right now. Woot!
[Epic 4G Android Development] akijikan:
I updated, fully charged the battery and did a battery stats reset. Now I'm fully draining. After that will fully charge and start measuring battery life.
[Epic 4G Android Development] 1deviant:
Love it...Love it...Love it!

Thank you very much for all your work!
[Epic 4G Android Development] aestil:
Can I flash this over the previous version of your kernel?
[Epic 4G Android Development] joshottley:
I just flashed stock with no problems. I don't see why flashing over another version would be a prob.
[Epic 4G Android Development] MysteryEmotionz:
Yes you can. Its s hole new kernal
[Epic 4G Android Development] aestil:
Will it also stop the phone from telling me to apply the new system update?

I'm still on DG27 and would like to update to the new OTA. Don't want to jack my phone up though. I have root and CWM recovery.

Phone keeps telling me to apply the system update, which I am of course ignoring. Just not clear if I should flash this directly over the old one, since the old one is based off the old OTA?
[Epic 4G Android Development] ipaq3115:
I'm not sure if the new kernal would work with the old software version.

If I were you I'd accept the update then get the DI18 update from here: http://xdaforums.com/showthread.php?t=797090

The first one that says Update to DI18 - flashes new DI18 kernel.

Before you do the first update I think you have to remove Root and CWM then add them back afterward to flash DI18 with.

Then of course you would flash mixup.
