I have tried 2.3, 3.0, and 4.0 on rooted stock. On all three using tegrak, voltage control, and now extweak, i see no usage above 800 mhz in cpu spy, and sitting in voltage control it shows my cpu pegged at 800. Nothing above or below.. Cpu spy shows deep sleep and 200 usage however.

I can tell it isn't working from benchmarks, also. Linpack only hits 25 for me. Strange thing is with either smartass or pegasus my phone is much more responsive. Even with the bug. And battery life seems improved.
[Samsung Epic 4G Touch] leaderbuilder:
Yep. used RootExplorer and that worked.

Without any overclock just got a 6634 Antutu score. [quadrant scored 3376] With some tweaking and settling in I'm sure I can better that and improve battery too.

Getting late. I'll have to toy with it on the morrow and see what comes of that.

Thanks again Agat (and Chris41G too) for all the work and support.

ExTweaks I get No Compatible Interfaces detected?
[Samsung Epic 4G Touch] Sloth:
If after running app (ExTweaks) you will get "no supported interface" message you would have to manually create a /data/.agat folder (note the dot before agat, it's very important). I had 2 instances when the folder wasn't created and I had to do it manually.
[Samsung Epic 4G Touch] konman21:
I'm having problems adding that DOT before

Agat, it will add without the dot.

"Operation failed please use a different name"

Adding at /sdcard/data/
[Samsung Epic 4G Touch] Sloth:
The only way I got it to work was to use Root Explorer :D
[Samsung Epic 4G Touch] 5FOOTER:
I used ROM toolbox and put it in data not sdcard data and it worked fine
[Samsung Epic 4G Touch] konman21:
Alright, purchased the app already it added the folder.

But my error was adding it to my sdcard data, that's why it

Didn't add before.

There goes 3.99 out the pocket
[Samsung Epic 4G Touch] jonathanclary:
Tried /data wouldn't accept name. So went to sdcard/data and worked.
[Samsung Epic 4G Touch] TheHighlightGuy:
Thanks for the work agat!

I was wanting to know if USB Host will be available at some point in the futute? I'm not asking for an ETA, I'm just wondering if it'll be possible.

Thanks!
[Samsung Epic 4G Touch] agat63:
I'm looking into it.

Reading a lot and lurking around trying to find anything about it.

I'm positive it's possible but the bigger question is if I can do it.

let's not forget I'm at the bottom of learning ladder there are a lot of things I can't do.

So can't be any ETA because first I should be able to answer the question:

"Can I do it?"

But I really wanna try to make it happened.

So, fingers crossed.
[Samsung Epic 4G Touch] TheHighlightGuy:
Thanks for the reply and good luck!! I'm sure you can do it man

Used Root Explorer to create folder,restart phone and app opens up, will not open without a restart.

I have not made any changes in ExTweaks, just flashed 4.0 , have noticed that battery percentage dropping faster than with 3.0 with no changes after flashing.
[Samsung Epic 4G Touch] agat63:
No other parts of kernel have been touched.

Small changes in defconfig and added ExTweaks support.

Clean up should not affect the battery life at all.

Let it run a bit.
[Samsung Epic 4G Touch] cdss:
Will run it for couple days and see what happens,after a second restart battery went from 59% to 20% , running ICE Rom.

Thanks Agat for your work on this,appreciate it.
[Samsung Epic 4G Touch] agat63:
Restart does weird things to battery.

Happened to me before.

After restart battery reading dropped from 43% to 17%.

Left phone sitting there without plugging it to charge.

Batter reading start climbing.

That was very initeresting to watch how battery % goes up with phone being connected to charger.
[Samsung Epic 4G Touch] s9amme:
That's always been a bug even with GB. The fix is to turn on airplane mode before you reboot the phone. The battery percentage should read correctly with that fix.
[Samsung Epic 4G Touch] PhAkEer:
Hate to bug you so only answer if you have time.

Not asking if YOU can but rather asking if it is supposed to be able to be done.

I don't have 256 being commanded from. anything directly so this surprised me since it doesn't fit within the requirements of the setting.
[Samsung Epic 4G Touch] agat63:
Can't recall for sure but I think I did it in init.rc and also increased SD read ehead.

Gotta check tho.
[Samsung Epic 4G Touch] mb3:
Not so much. Still drops. I never saw this with GB.

We all on same page here and want to get as much as we can from our phones.

I hope I can add that option to kernel some times soon.
[Samsung Epic 4G Touch] agat63:
OK guys.

We are approaching 400 downloads for 0.4.0 now and you have nothing to say?

Before I move forward and try to implement more mods to the kernel I've gotta know that this one is OK.

No bugs or problems.

Please give me some feedback so I know what direction to move.
[Samsung Epic 4G Touch] PhAkEer:
Don't know what you're looking for, but I've been using it today and have had no issues.

The only thing that Im having a problem with is Modding that power save governor..

Any chance of seeing conservative in the future?
[Samsung Epic 4G Touch] agat63:
Conservative shouldn't be a problem.

I'll make sure it's part of next release.

I hope I won't forget it. ;)

That tweaks app is it supposed to set on boot, it doesn't seem to be doing it
[Samsung Epic 4G Touch] PhAkEer:
That'd be kind of you, sir :)

I need to stop procrastinating and just get myself a legitimate setup... I just need some crappy PC and I'll just convert a 32 x10 sdcard into a Linux boot...

I've been wanting to play with kernels since before I..hell... its what got me into IO tweaks in the first place.

Would there be anything stopping me from compiling on a on kernel via AndroidVNC? I can boot up umuntu and it runs smooth, but I haven't actually made on there... ( cause of the interface )

Noob question: Can this kernel fix ICS wifi diconnect issues that everybody's been having with stock FF18, blazer rom?
[Samsung Epic 4G Touch] agat63:
Don't know what problem you talking about.

Never had any disconnect issue with my wifi.

Connects autmatically as soon as a known network is in range and stays connected.
[Samsung Epic 4G Touch] agat63:
I know that's PITA to do it manually.

I'm thinking I have some permissions problem in the kernel and that's why the folder is not created automatically.

Will be looking into it tonight and hopefully can fix that problem.

Theoretically folder should be created automatically when support is there on first run of ExTweaks apps.

uci.sh script wich is included in kernel is runed by ExTweaks and it looks for a foder described in helper script (/data/.agat). If folder is not there it should creat one.

I guess I missed something when implemented these tweaks from siyah kernel.

Hi agat63,

One of the places this issue is described is here at the top of the page: http://xdaforums.com/showthread.php?t=1363071&page=858

I'm charging my my phone now to install your latest kernel, 0.4.0, over the blazer rom kernel. Going to install AGAT_v0.4.0.zip from agat recovery as soon as it is charged.
[Samsung Epic 4G Touch] agat63:
Read it and kinda surprised.

I have wifi on all the time and when home I'm on wifi only.

Never had a problem with reconnect.

I should mention tho I'm running my tFF18 rom and my kernels only.

With all my attempts to develope I just don't have time to try anything else and beside I know my rom is not the greatest or anything but to test kernels I have to know that rom is working and if I see anything broke I would know it's a kernel issue.

If I would run different roms it would be harder to tell what causing the problem.

I'm trying to read thru other rom threads and trying to follow them but honestly not enough time for all of them.
[Samsung Epic 4G Touch] delfin2003:
Totally understand! Thank you for all your hard work :)
[Samsung Epic 4G Touch] tdunham:
Never enough time Ag. ;)

The wifi thing has been around for a while but doesn't affect everyone. Typical symptom is disconnect after coming out of sleep even though wifi signal shows connected. Even happens on stock rom so cannot be blamed on a tweak. But hard to fix because it does not happen to every phone or a particular setup. :(

Sent from my SPH-D710
[Samsung Epic 4G Touch] agat63:
That sux.

If you can't recreate error hard to fix.

I guess I'm the lucky one since I never had the problem.

Even when I was out of country and setup the wifi for place I was it reconnected every time without any problems.

And also would reconnect when I left the place and then came back.

Since we know Samsung doesn't have 2 phones that are same it's might be a hardware problem as well.

[Samsung Epic 4G Touch] cas8180:
Regarding wifi I get consistent repro. I get the reconnect issues when leaving the device alone for a while. Also massive battery drain and I believe this is related to the fact that when on Wi-Fi the device never goes into a deep sleep.

On another note you can find tons of people reporting these same exact issues on sprint's community forum site as well as our general section. I have also contacted sprint and they are aware of the issue and have notified Samsung....
[Samsung Epic 4G Touch] agat63:
Had wifi on all night (never turning it off) and CPU Spy shows 57% (over 9 hours) deep sleep.
[Samsung Epic 4G Touch] cas8180:
Guess your device isn't exhibiting the bug but many of us do have it....
[Samsung Epic 4G Touch] agat63:
May be we should take a closer look at rom/kernel/tweak/mod combos.

I know there are too many and it won't be an easy task but if we wanna try to find a fix we should

find a root of the problem.

I guess the issue might be caused by build prop tweaks of the rom or some init.d scripts.

Just an idea tho.
[Samsung Epic 4G Touch] cas8180:
Honestly I can get it with just a stock FF18 odin flash with NO mods all factory. I did the full wipe and all the voodoo tricks people posted many times I just genuinely feel like its a bug possibly in the kernel. I can tell you this when I flash back to EL29 I dont expierence any issues at all and wifi works good. I have been monitoring everything with CPUspy and GSam battery

Just an FYI of other reports.

It's hard to find solution to a problem I don't have or I haven't seen.

Since not everyone has it may be it is a hardware issue?

As mentioned before I'm on my rom with my kernel all the time.

And lot of people using my kernel with other roms. If the problem is in kernel we should of hear more about it.

I'm not trying to defend my work just trying to understand what is causing the problem.

If we can determin with certainty that it's a kernel problem I'll gladly fix it.

Well I know I can turn wifi on and give you a screen shot of my device never going into a deep sleep. But I am sure you need lower level logs. So what can I do to provide the info you need for your diagnostic?
[Samsung Epic 4G Touch] agat63:
Which brings us back to a possible hardware issue.

If no matter what rom/kernel you flashing you still have the problem (not you personally but general statment) it might be not software related?
[Samsung Epic 4G Touch] agat63:
you should either:

1. Run a logcat and save it to a txt file

2. run dsmeg log and save it to txt file.

May be not me (don't thing I'll be able to tell heads from tail) but someone else with more knowledge can give us an idea what is happening and how to fix it.
[Samsung Epic 4G Touch] cas8180:
I can do that Agat. No problem. However not be insulting or anything but with that many people reporting the issue ( I mean just a little googling searching will bring up other reports the list goes on and on) I find it hard to believe its hardware related it might be an issue on how the implemented it with specific hardware sets and didnt properly QA but my device is literally 3 months old as well...
[Samsung Epic 4G Touch] 5FOOTER:
Not the kernel I'm on blazer 1.3 or 1.4 beta and have not had that issue with any of your kernels. Mine deep sleeps like a baby or a drunk father.
[Samsung Epic 4G Touch] agat63:
Mine gets into deep sleep almost immediatly after screen turns off.

That's why it is hard for me to look for solution.

I'm not saying that people don't have it or it doesn't exist.

All I'm saying is I can't fix a problem I don't have. May be with logcat and/or dsmeg we can figure it out.

But as of this moment I'm lost and can't do anything bout that.
[Samsung Epic 4G Touch] tdunham:

I've been running 4.0 for a couple days now on smartass governor and it's been great. Overclock still gets a little sluggish after a while but I think that's expected. Btw my WiFi must be as good as urs lol cause I have zero issues. Also people there are multiple WiFi keep alive apps on the play store that are free and I'm sure they would help ur issues. One in particular that I'm a fan of was Repon Wi-Fi keep alive. Thanks again agat for all ur hard work.
[Samsung Epic 4G Touch] cas8180:
Problem is that Keep Alive often = Keep Awake and you can test this with GSam battery app or better battery stats. And for us having the issue when we do wake our device it will often show as connected. But there is no internet access you have to toggle the wifi radio on/off to get a connection back. Its annoying as hell.

@Agat,tdun

So just a quick update. I reflashed my ICS build I had a custom ROM I have been using for sometime its based off PH 0.13 and I just updated the kernel on it to Agat 4.0 flavor. I am using Tegrak as my app for controlling Goveners and I am currently running SmartAssv2. I have also undervolted every step -50mah to squeeze every bit of battery life I can out of this puppy. I just installed catlog and turned wifi on. I also reset all my timers in CPUSpy so I can effectively monitor if my device goes into a deep sleep while on wifi. So right now I am count to let these monitoring tools collect a good sample and then I can post the logs/screen shots here if needed.
[Samsung Epic 4G Touch] Subiegsr:

Nope.

Not on /sdcard/data but in /data

got a question.. maybe its been discussed, but what is causing the kernal to lag down after 1.3ghz!? or lets say, why is overclocking slowing and lagging down!?
[Samsung Epic 4G Touch] agat63:
I don't think it's kernel.

I think it's the chip itself.

But I might be wrong.

List your OC w/ voltages...

And as agat stated. It maybe your chip.

It does stick on boot.

You sure you gave ExTweaks SU permissions?

AFAIK it works with sprint phones but has some problems.

If it has some improvements from FF18 I might make a rom.

Gotta read more about it I guess.
[Samsung Epic 4G Touch] bigpeng:
It is boost mobile but can just be switched to sprint with few changes. I don't think it's any better, your time is better put into the kernels. I :D;)

I click accept everytime it asks ,How do I check to see if its sticking, I opened tegrak and it said the default rom settings not what tweaks said

On mine v4.0 kernel there aren't any cpu apps that will list CPU settings above the stock 1200, is it possible to overclock without using tegrak ?
[Samsung Epic 4G Touch] agat63:
You can overclock with ExTweaks app.
[Samsung Epic 4G Touch] SweetwaterBurns:
I am having the same issue. No matter what i do, no oc(even using extweaks) i can tell because benchmarks are pretty much the same.
[Samsung Epic 4G Touch] agat63:
Well.

After reading your post I did some tests and got interesting results.

I did install Tegrak Ultimate and changed settings in Tegrak.

Reboot the phone.

Tegrak and Extweaks are showing different scheduler and governor.

I don't have any explanation for that tho.

They should show same settings.
[Samsung Epic 4G Touch] ewilley2008:
When I change the scaling freqs in Extweaks then check in other apps the freqs are still stock

Really great battery yesterday on .4 kernel with wifi set to off when sleeping. CPUSpy said 200mhz and deep sleep about equal percentage.

Set wifi to never off today and CPUSpy says 0% deep sleep. Battery usage shows wifi never shut off but I had problems at least 8 times with having the wifi icon disappear and the 3G took over. Ended up manually disabling/re_enabling wifi to get reconnected.

Same issue yesterday with the wifi not connecting when waking from sleep. Just about twice the drain today without any noticable advantage in connectivity for me.

[Samsung Epic 4G Touch] agat63:
Quick update.

Was talking to Chris41g on IRC.

He told me that Tegrak is using external modules and it doesn't touch the kernel/kernel settings.

Thus it reports it's own settings. Different from what set in kernel.
