You mean every CPU reacts differently even under the same exact test conditions. ;) They may be identical chips but in the real world they're different somehow.

Undervolting is a really good example. I could undervolt to -100 with no problem, the next guy may only be able to UV to -75mv, the third guy's phone will work at -50mv & -100mv but his phone won't boot at -75mv. All the same applies to overclocking (of course using UV and OC at the same time is not recommended anyway).
[Samsung Epic 4G Touch] s9amme:
I flashed the latest kernel this morning. Using the smartassV2 gov and set up my profiles to -25mv from stock values and limit to 800mhz when the screen is off and in calls. Getting much better battery life so far halfway through the day. I'm at 63% battery with 1 1/2 hours of display time. I'm on pace to hit 3+ hours! Almost GB battery levels.

Going to undervolt with -50mv tomorrow and see how it goes. Thanks for all the hard work Agat!

Voltage Control Extreme (paid one) seems to be working for clock and voltage settings but I done see overclock yet. Does it have to be enabled with an adb command?

Sup JC. With Tegrak Ultimate I was able to OC up to 1.4(1.3 in the screenies from a cpl days ago). I didn't need to mess with adb.

Bigger pics here.
[Samsung Epic 4G Touch] tt281gt:
Try downloading free Tegrak and see if it has the option [free one is a little limited though]
[Samsung Epic 4G Touch] sniper:
The free tegrak can over and underclock, but you can't change the voltages.

[Samsung Epic 4G Touch] dohchp:
I have been running this kernel all day. Im under clocked to 1000mhz and for the first time since owning this phone it went all day without charging. I use my phone quite a bit for work so i think this is pretty awesome.
[Samsung Epic 4G Touch] localguyincali:
running AGAT_v0.1.1 kernel, No setcpu or anything :good:
[Samsung Epic 4G Touch] sjsharksfan420:
Im missing something.. How would i overclock to 2g?

Ive tried tegrak but it still only goes up to 1.425g max..

Im not very familiar with using tegrak for custom frequencies..

sj
[Samsung Epic 4G Touch] agat63:
If you using Tegrak ultimate (don't know if free version has that option) go to optimization/frequesy.

First frequency option (1200) will allow you to go up to 2000.
[Samsung Epic 4G Touch] s9amme:
so what's your screen time? ;)
[Samsung Epic 4G Touch] yellowman82:
That's what its all about to me screen on time lol if I wanted 3-4 days ill just let my phone sit in idle and not use it but meh these phones was meant to be used lol
[Samsung Epic 4G Touch] localguyincali:
roughly a hour or two or so, i don't camp out on my phone, like web surfing, tapatalk etc etc, just heavy txtn, emails few calls here and there, mind you i'm running stock rom only thing done to it is rooted with all of sprints bloatware! i just wanted to see how this kernel ran, i'll flash a rom in a bit and use same kernel, like i said other day, used kuban rom with his stock kernel ( not his new one ) and battery life was bad! so i'll try his rom again but with this kernel,
[Samsung Epic 4G Touch] FrankAmato:
Im pretty sure that was a typo agat XD.. just lookin out for you
[Samsung Epic 4G Touch] sjsharksfan420:
Ah, thank you kind sir, i havent used tegrak much since i paid for ultimate version and then started having trouble with it (i thought)

Thanks again Agat!

sj
[Samsung Epic 4G Touch] agat63:
2000 is not typo unless Tegrak makes it up.
[Samsung Epic 4G Touch] MiguelHogue:
Just get something dialed in and let it settle.. Battery life is there.. Don't let your phone out smart you :thumbup:

I will never click ok on 2k, but I definitely DO have the option.

Im curious though, is there a way for me to adjust the lower steps? I cant overwrite /sys/power/cpufreq_table no matter what I try...
[Samsung Epic 4G Touch] agat63:
New kernel uploaded.

OP updated links posted.

Added new features and tweaks.

Hope for some added battery life.

Don't have phone yet (will get it tomorrow) so wasn't able to test it.

It should work and won't damage phones. No worries there.
[Samsung Epic 4G Touch] DataHawg:
Thanks Agat. We've been saying for months great things would come with source code and you are proving that.
[Samsung Epic 4G Touch] agat63:
I'm not alone bro.

I'm getting a lot of help from other devs.
[Samsung Epic 4G Touch] leaderbuilder:
Well it's running great! Well see how battery lasts throughout the fatty tomorrow
[Samsung Epic 4G Touch] probowler2009:
Will the update 0.2.3 work with blu kuban romantic?
[Samsung Epic 4G Touch] agat63:
If the previous one worked than this will too.
[Samsung Epic 4G Touch] localguyincali:
Flashed rom kubans along with his RC1 kernel, i have setCPU installed and set on intellidemand / sio / MAX 1000 min 200 i had it at 800 but seemed little laggy opening stuff so switched to 1000. My question is, i know from EVO days we made a profile for sleep/screen off for when we werent using the phone,My question is im in the settings made a profile for screen off, it says priority of this profile its set on 50 now, should that be changed higher or lower?
[Samsung Epic 4G Touch] agat63:
Honestly can't answer that question.

I'm on my rom and my build.prop sends phone to deep sleep very fast.

I never thought about it and never tried since I know my phone is in deep sleep within seconds after screen goes off.
[Samsung Epic 4G Touch] localguyincali:
hmmm, i wonder how i can test/try this to see if it sleeps right away?
[Samsung Epic 4G Touch] agat63:
You can try cpu spy.

Free from play store.

It will show percentage of frequencies phone stays on. If you phone goes to sleep fast you deep sleep bar and % will be biggest.
[Samsung Epic 4G Touch] localguyincali:
Thankyou just dloaded it i'll give a try and see what happens :)

[Samsung Epic 4G Touch] t4d73:
Anyone else getting some page with code on it when they hit download link for 2.3 on dev-host?

Edit: dev-host seems to just be having issues I guess. Can't wait to try though.
[Samsung Epic 4G Touch] tdunham:
It's only the Tar link. The zip dev-host link is working fine. Can't really flash the tar with mobile odin anyway so I'm fine with that.
[Samsung Epic 4G Touch] t4d73:
Yeah I see the download count going up but I can't seem to get it. Have to try later from my pc I guess. I'm trying to get the the zip file.

Edit: finally got it! Time to flash.
[Samsung Epic 4G Touch] kiswa:
The zip file is failing for me.

I don't suppose there's a mirror anywhere?
[Samsung Epic 4G Touch] t4d73:
I just kept trying and finally I got it.
[Samsung Epic 4G Touch] kiswa:
I guess I'll just keep hitting refresh then. Wish me luck!
[Samsung Epic 4G Touch] t4d73:
Good luck! I'm on the new kernel now. Overclocked to 1.3. See how this goes.
[Samsung Epic 4G Touch] t4d73:
Well this it's working out just great! I installed the kernel and rebooted. Once it booted I rebooted again. Overclocked with tegrak and it's holding strong at 1.3. No longer getting sluggish after a couple min or anything! Haven't gone past 1.3 but just gonna see how it does after an hr or two. So far so good! Great work!
[Samsung Epic 4G Touch] SSaxman:
If the screen off profile is the only profile you have set up, then the priority doesn't matter. Priority comes into play when you have multiple profiles in which case you would set a higher priority for the more important profile. For example, let's say you set a profile for when the battery is less than 50% and one for when the battery is less than 40%. You would set the priority of the 40% profile higher. If the 40% profile had a lower priority, it would never go into effect. Make sense?
[Samsung Epic 4G Touch] flamebeats:
Can some one post mirror because file host is not working
[Samsung Epic 4G Touch] t4d73:
Just keep trying and u should get it.
[Samsung Epic 4G Touch] t4d73:
Ok so I noticed there is a new sio scheduler. Anyone really know what the scheduler does. Guess I'll Google it lol.
[Samsung Epic 4G Touch] t4d73:
So after messing with this for quite a while and trying all different combos and scenarios, I found that it was best to just reboot and leave this kernel alone and leave it the way it is without overclocking or even changing the governor from what it comes with.
[Samsung Epic 4G Touch] jonathanclary:
I am having no luck with .zip download. Sends me to the download page, I click the link, almost a minute later I end up at an error page.
[Samsung Epic 4G Touch] mcadamry:
To all who think

It's not.

It's more inconvenient.

JUST KEEP CLICKING.

I almost gave up.
[Samsung Epic 4G Touch] t4d73:
So I went back to 2.2 kernel. It just seems a little more stable cause even after touching nothing and leaving 2.3 settings as is it still seemed to get a little sluggish over time.

Is anyone else having a problem flashing 0.2.3? When I flash from AGAT_Recovery 0.2.1, it says "Flashing AGAT_v0.2.3 with tREC_v-.2.1... Install from sdcard complete."

Orbot Transparent Proxying Not working with kernel

I have tried using both the 0.2.2 and 0.2.3 versions and neither allows Transparent Proxying while using Orbot. I have gone back and tried the stock one and it works just fine with Orbot. Did you change anything with the Iptables? I can't figure out why it isn't working with your kernel :confused:
[Samsung Epic 4G Touch] rwilco12:
Just finished uploading Agat's latest source-built recovery to the Kernel Repo!

It's available in TAR, ZIP and One-Click.exe formats.

Enjoy!
[Samsung Epic 4G Touch] hollywood084:
I get I9100 Splash with a yellow boxed "!" after installing 0.2.3 one-click. My recovery still shows 0.2.1
[Samsung Epic 4G Touch] agat63:
Just checked the zImage in zip file.

It's dated 7/19. Should be correct one.

As I said I don't have phone to check/test it.

If tar file has a correct zImage you guys can pull zImage from tar and place it in zip file for flash in recovery.

But I see more than 130 downloads of zip file and only few posts about it flashing 2.1.

Please zim file users chip in and let me know if you all getting 2.1 as kernel version in "about phone".

Edit: Downloaded tar and zip files and compared zImage files in them. Bot files have exact same size 7,797,072 bites and both files have same timestampt 7/19/12 at 21.25 pm.

So either bot zip and tar would flash 2.1 or both would flash 2.3. There should be no difference.

I'll pick up my phone at noon today and will try to flash both.
[Samsung Epic 4G Touch] ewilley2008:
SetCPU still not overclocking in 2.3
[Samsung Epic 4G Touch] hollywood084:
Yes, I actually just checked "About phone" after I updated the kernel via ROM updater to v0.2.2, and it showed 0.2.2. I installed 0.2.1 One click, still have GT-I9100 splash screen, but About phone recovery showed 0.2.1. Flashed 0.2.3 zip and "about phone" shows 0.2.3, I should have checked about phone sooner :). I don't know why I'm getting the GT-I9100 Splash now, but whatever. My splash screen only changed to GT-I9100 when I used the one-click version of 0.2.3, and not the zip.
[Samsung Epic 4G Touch] agat63:
I checked cpufreq.c yesterday. Frequencies are populated and should be seen by other apps.

I'm leaving country today and will be back late Tuesday. Any fixes and edits will be done after I'm back.

I'm not taking my laptop with me so I won't have any tools to work on anything for 4-5 days.
[Samsung Epic 4G Touch] hollywood084:
Confirmed with AnTuTu CPU Master, here.
[Samsung Epic 4G Touch] agat63:
I have used some files from initenational galaxy for OC/UV/UC so that might be the cause of GT-I9100 splash screen.

As for kernel and recovery.

Recovery is still version 0.2.1 but kernel is 0.2.3. That might be the confusion.

When booted to recovery you guys see recovery verstion and not the kernel version.
[Samsung Epic 4G Touch] hollywood084:
Yes, I think that is the confusion! No big deal. I think it was missed with my late edit, but I wanted to add that it only changed my splash screen with I used the one click, and not the zip, if that helps anything.
[Samsung Epic 4G Touch] s9amme:
Another update?! sweet! I'm still testing out 0.2.2 before I update it to see the differences. I've been getting much better battery life now since the last update. Thanks!

BTW, I kept getting mysql error text when downloading, just keep trying, it'll eventually let you download it
[Samsung Epic 4G Touch] feyrune:
If you used pc odin to flash the tar, you get the yellow triangle. Use a usb jig ($2 or make it yourself) or download Triangle Away ($2 or free from xda thread).
[Samsung Epic 4G Touch] 5FOOTER:
Running great so far on 2.3 about phone shows 2.3 also used the zip.
[Samsung Epic 4G Touch] t4d73:
Anyone else getting sluggish on 2.3 after a while? Was really bad for me and all I did was flash the file. No tegrak or setcpu or anything. Mflops were in the 30s on linpack. This after 3 flashes as well. Anyway back to 2.2.
[Samsung Epic 4G Touch] hollywood084:
Weird, I never got that before. Flashed odin recoveries/roms a bunch of times.
[Samsung Epic 4G Touch] musclehead84:
Using Odin on a PC will trigger the yellow triangle if flashing a custom kernel. If flashing stock it won't. Using mobile Odin will not trigger the yellow triangle.
[Samsung Epic 4G Touch] okantomi:
I have v0.2.3 #2
[Samsung Epic 4G Touch] agat63:
You will get yellow triangle only when flashing kernel.

If you flash full restore/rom/modem via ODIN you won't get yellow triangle even if kernel is included in full restore rom.
[Samsung Epic 4G Touch] sjsharksfan420:
Well.. I'm slightly frustrated.. I'm not sure what i did wrong, but I'm running goodness v16.5, went to flash the updated kernel Agat posted, booted into recovery (Agat 2.2) didn't wipe data or anything, just cleared cache and dalvik, updated kernel, but when I rebooted, I went to go put the kernel on my ext SD, and I lost all my data .. all my recovery backups gone, rom backups gone, kernel and modem backups gone..

I don't understand what happened.. :/ I'm not screwed cause most apps and account info I use are cloud based so its just time.. but I need to find out what happened to prevent it from happening again..

I actually ran a backup to see if it hung on data, and backup went through and I restored that backup.. so I know I'm not bricked, but I'm kinda scared to do a restore from my PC cause if it hangs on data then, I'll be screwed..

Anyone have any ideas?

sj
[Samsung Epic 4G Touch] agat63:
WOW.

I have no idea what it can be but even if you format data/system/cache and make a full wipe etc it never touches your sd card.

Can't even imagine what could of go that wrong.
[Samsung Epic 4G Touch] sjsharksfan420:
me either.. no worries.. the internal card is all there so all backed up apps are still there..

The other really weird thing was only 3 folders that I could tell got deleted, my backups, my roms and ringtones.. (I saved some favorite copies for easy access..)

I have a feeling that since its a 16 gb card and I was updating and removing old data yesterday.. maybe it just crapped out on me.. I am thinking it is a completely isolated issue

sj
[Samsung Epic 4G Touch] s9amme:
Definitely a isolated issue I think. I can't see how flashing would touch the ext sd card. I just updated to the latest kernel, just to verify. I did the same procedure. Wiped cache and dalvik, flashed the kernel, then rebooted. All my data is still intact.
[Samsung Epic 4G Touch] sjsharksfan420:
Yea.. I just feel so naked when I loose backup data.. :/ my fault for having the SD card not backed up itself on my PC.. I used to do that all the time but started laggin on that lately .. bit me in the ass this morning.. :/

I already have goodness backed up, just finished BluKuban.. gonna do super Nova and CM9 later and save a back up..

The ONLY backup I'm frustrated about loosing is my AoKPm5 .. I had that one set up perrrrrrfect..

sj
[Samsung Epic 4G Touch] dlgltal:
I ODINed 0.2.3, used jig to clear yellow triangle and everything was running great. Using as is on Blu Kuban, no tweaks. This afternoon I could only get 30k speeds on 3G so I turned on 4G and got the 4G reboot after 3 minutes. I only had that happen once before, back around FE07.

Is there something I need to address?

@agat

I know if anyone reported this or not but with the latest kernel I can never scale all the way up to my highest step. No matter what I set it too CPU spy always shows me pegged at 800mhz and I also confirmed this in quadrant standard when you go to system info says current freq is 800mhz. Now if I flash back to kernel 0.21 I can scale all the way up with no problems. However then my device never goes into a deep sleep which is kind of weird I can only go into a deep sleep state with 0.23

Anyone else have similar issues?

EDIT:

After a little more testing with 0.23 kernel after a reboot I could then get my device to scale to my highest clock speed tiny case 1300mhz however it would only maintain this speed for a short while even though I was actively using the device. It appears to quickly scale down to 800mhz and hold there. I was able to reproduce this behavior wth both the ondemend and smartass goveners.
[Samsung Epic 4G Touch] g_ding84:
I'm not over locking but I can get mine into a deep sleep. And it scales up to 1200. (Sorry not a fan of OC)
[Samsung Epic 4G Touch] g_ding84:
What are you using? I had to switch to voltage control from tegraz because it was really laggy and rebooted a few times. Made the switch and phone is running nice.
[Samsung Epic 4G Touch] Shadow_God:
I am using CPUEditor on battery Saver and running at max 800mhz....and uv a lil
[Samsung Epic 4G Touch] caspersfi:
I'm stumped on something along this line. I'm not concerned about battery right now just want to see what kind of performance I can get out of this phone by overclocking.

I'm overclocked to 1.4 using Tegrak. I also increased my voltages by 50 across the board.

My question is why is my phone barely ever running at 1.4 but basically stuck at 800. I thought by running performance gov. and increasing the voltages that would help with keeping my phone at 1.4 most of the time rather then 800.

Any ideas?

TIA

[EDIT] Bigpeng's been helping me out on this thru Gtalk. I'm gonna try changing my scheduler to cfq for a bit..... see if that makes a difference. I'm not familiar enough with schedulers yet so I've got some reading to do. From the little I have read it seems cfq is more of a performance scheduler.
[Samsung Epic 4G Touch] tim1089:
2 days running no lag yet

Here is my screen shot. Battery is doing great. I did go from 2.2 to 2.3
[Samsung Epic 4G Touch] chris-allen:
same here...i thought it was just me.... do share what u find out!
[Samsung Epic 4G Touch] cas8180:
Had the same issue I switched govener to performance in tegrak. Then I oc'd to 1.3ghz and went -50mah on each step to effectivaly give the perfect balance of battery life and speed. I also now ramp up to 1.3ghz without issue and everything seems very stable.
[Samsung Epic 4G Touch] caspersfi:
Morning ya'll. Well just woke up and checked my settings and this is what I got. Quite the improvement. :) Couple things tho... I'm testing a new kernel from sleshepic AND I changed my scheduler to Deadline.

So I would suggest anyone else with this problem to play around with some different schedulers. Also, big props to Team Venum. What a great group of helpful guys. :)

Will be testing more as I use my phone today and see if the settings continue to stick
[Samsung Epic 4G Touch] abhaxus:
I installed 0.2.2 this weekend and i see the same 800mhz bug with both tegrak ultimate and voltage control free. Unless i set governor to performance, cpu does not go above 800mhz. Even setting min and max to 1504 does not help, only performance governor. Hope this helps.
[Samsung Epic 4G Touch] caspersfi:
Alright guys, I guess I'm just stumped and gonna have to read around some more. I've tried different schedulers with some improvement on my 1.4 on time.

Now I'm wondering why not only is alot of my time spent at 800 but it barely ever goes below. Why is my minimum set at 200 if I'll be sticking at 800 so much of the time? Maybe it's because at this time my voltages are increased.

Gonna try RJ'S RC1 kernel next..... If that doesn't do it might switch over to Setcpu rather then use Tegrak.

I am keeping in mind though that source just recently came upon us so I'm not blaming any of our great kernel devs. Just thinking there has to be some kind of setting I'm missing.

---------- Post added at 04:14 PM ---------- Previous post was at 03:36 PM ----------

Just gonna bump this one time...... looking for any ideas or suggestions.

TIA!:)
[Samsung Epic 4G Touch] PhAkEer:
not sure if this helpful or not but I ran into this a few times while getting placebo up and running..

I couldn't always track it, but a couple of times it was due to sloppy usage of *s in scripts, but mostly hit this when I was writing a screenstate scaling script and this happened if the coding was off. .. even if I never once said 1000000... it was my min..

sorry I can't help more.

do you have any scripts that use

while (w/e)

do

if $?

very few pieces of code that you see on android would actively overwrite a cpuctl apk
[Samsung Epic 4G Touch] caspersfi:
Appreciate the feedback bro but no.... I'm not running any scripts. These cpl of screenies here are with RJ'S RC1 kernel running cfq as my scheduler with Setcpu and leaving the voltages untouched.

IDK man I'm running out of things to try. I guess today I'll go back to Tegrak and start trying some different governers. I just don't know enough about kernels yet to understand why I'm so stuck at 800mhz.

[EDIT] Sorry Agat/guys I should probably open a thread on this over at Q&A. This is kind of getting away from Agats awesome work.
