disabling those + unloading stuff from memory would generally edge the benchmarks a little higher...but i wouldn't think idle it would make that much of a difference in a pure sql bench

Thank you thank you thank you. Rodderik you da man.
[Epic 4G Android Development] Rodderik:
on the eve of OTA (i hope) i present to you

https://github.com/Rodderik/Genocide-Kernel-EB13

i encourage everyone to fork the kernel and if you do anything cool with it please let me know what you did so i can consider adding the changes
[Epic 4G Android Development] jbadboy2007:
Then do kill all process's or re boot
[Epic 4G Android Development] herzzreh:
I tried that of course. Looks like it is that 0 process... Cleared dalvik cache and enabled network location and it went away. I wonder what causes it to run out of control...

Any plans for a Vanilla version?

Are there any plans to make a vanilla version of this kernel, flashable w/ heimdall, and w/o the Voodoo Sound or Color mods? I have a Epic 4G and a Galaxy Tab, the Tab has a 1.4Ghz OC (no UV) kernel and runs like a dream. I am trying to find something simmilar so i can run my Epic at 1.2 or 1.3 Ghz but don't want to have to use Voodoo mods, CWM, or anything like that. Thanks for all the great work!
[Epic 4G Android Development] Rodderik:
no i don't plan on maintaining different versions. you should be able to download the kernel and extract the zImage from the .zip file and flash that with heimdall

may i ask why you don't want the voodoo mods? no one has complained about them and there isn't anything you HAVE to install or do.
[Epic 4G Android Development] J3ff:
sigh I'm such a newb.

I get "installing update" and then "installation aborted"

I'm running the Syndicate EC05 ROM. :-/

I'm sure this means I just dont have something setup right, but the kernal that came with syndicate is horrible.
[Epic 4G Android Development] Rodderik:
re-download the kernel and try again
[Epic 4G Android Development] J3ff:
thanks for the advice.

Is it possible to uv deep sleep state more than what it possibly might be?
[Epic 4G Android Development] Kitteh298:
My phone did not like ec05 and this kernel. It would not wakeup or respond at all when the screen turns off.

Sucks

[Epic 4G Android Development] squshy 7:
Eww..that sounds like bad news bears. ive heard alot of reports (myself included) of ppl only losing about 1% an hour when the phones sleeping...that sounds good enough to me... This isn't perpetual motion you know lol
[Epic 4G Android Development] mis3:
Started setting undervolts now... Just curious, can anyone tell me how much some of the kernels out now (ie, twilight, vision, bonsai) undervolt their frequencies? I'd like to see how my settings compare.
[Epic 4G Android Development] Custodian:
Contact sprint and demand a new phone. Good luck.
[Epic 4G Android Development] Custodian:
Mostly if not all kernels on these boards are undervolted. Many aren't compatible with the latest voltage control release just yet. But I strongly recommend using any up to date and future genocide releases, even the betas....unless, your phone dislikes genocide :-)
[Epic 4G Android Development] Custodian:
Its called a coma. Lol.
[Epic 4G Android Development] Rodderik:
with deep sleep the phone is actually turning the processor OFF so no we can't undervolt null current
[Epic 4G Android Development] theimpaler747:
Lol, but I want negative voltage!!!!! :p :D You have really done a nice job with this kernel man, keep it up :)
[Epic 4G Android Development] Rodderik:
how i would love to stuff a flux capacitor into the kernel code to trickle charge your battery while it sleeps...i don't think we have the technology yet
[Epic 4G Android Development] mis3:
I guess I wasn't clear. I know most of the kernels are undervolted, I'm wondering by how much (25?, 50?, 75?). ie, if I undervolt by 50, is that more or less than say latest version of twilight?
[Epic 4G Android Development] theimpaler747:
Standard is usually 25. And the next version of twilight and vision have the custom UV as well :)
[Epic 4G Android Development] Rodderik:
you will have to look on their github at the file: Kernel/arch/arm/mach-s5pv210/victory/max8998_consumer.c and look at the table "frequency_match_1GHZ"

for example in my source it starts on line 87 https://github.com/Rodderik/Genocid...h/arm/mach-s5pv210/victory/max8998_consumer.c

in that table you will typically find 4 values and ill even explain what they are...

{1000000, 1275, 1125, 4},

in that example { cpu frequency, arm voltage (this is what you are undervolting), internal voltage, frequency step }

so in my example 1275 is the value you are looking for

hope that helps...happy hunting
[Epic 4G Android Development] mis3:
Thanks, appreciate the answer. Right now, a couple hours of testing in and 4 freezes later, I'm using

200 -75

400 -75

600 -50

800 -50

1000 -50

1200 -50

Wasn't sure how much time to dedicate to pushing for more. Knowing that most uv's are 25, I'm feeling better about these numbers, though still jealous of those whose phones seem to be able to handle much higher.
[Epic 4G Android Development] Rodderik:
ya some of these guys are getting pretty insane undervolts...i'm impressed
[Epic 4G Android Development] theimpaler747:
At least they say they are ;) :p I'm set up like this, starting from 1.2 and going down:

-25

-50

-75

-125

[Epic 4G Android Development] volkly:
thanks for the awesome kernel!

I can OV by 100 on all ranges stable except for the 600 MHZ, had to use 75 or it will freeze, but can;t overclock anything beyond 1 ghz even at stock voltage =(. still battery life has been excellent, heavy use, and lasting 10-11 hours
[Epic 4G Android Development] aleph23:
You're not alone. I can run stock ec05 fine, but I wake lock on any custom kernel I've tried.

And yes, it does suck. Stock sucks. :(
[Epic 4G Android Development] thatdudepoops:
Rodderick I must say this kernal completely blows my puny mind, well done sir, well done. Before, I was restricted due to fear of use/distance awy from an plug-in....

But NOW tho..I am free to roam and play in a world without outlets and wires in my back pocket:-)...

I ran Pandora for 5 hours today, with some long phone calls, browsing ...really try it hard....after a 10 Hour day at work...I was at 33%! $*%@ing 33%. That's like 3x the battery life I usually get..I will fuel ur ego on this one:-) ur efforts in this war on battery consumption have not gone unoticed

I'd show u my set up but for the life of me xda wont upload cus of invalid format?..but ill post it if asked:-)

have a good trip, and take it easy :)
[Epic 4G Android Development] yogi2010:
i am curious as to what seems to freeze your phone the most when playing with undervolting? i could swear, for me it's web browsing..... i have tried with several different browsers, and that is what does it every time. if it wasn't for web browsing, i feel like i could get away with some wicked undervolting. there may be other things that would do it that i don't use much, but browsing for sure....
[Epic 4G Android Development] dchawk81:
Other than the obvious CPU intensive stuff, for me it seems to be, of all things, shutting down.
[Epic 4G Android Development] yogi2010:
hehe damn, i've had that one before too.
[Epic 4G Android Development] dchawk81:
I think it's because of those stupid images used to mimic an animation.
[Epic 4G Android Development] jbadboy2007:
My current config I haven't set as boot yet but I would freeze phone then dial back. So should be good.

1000-100

800-100

600-75

400-150

200-150

100-175

600 mhz step is annoying me that I can't uv it more. And 100 mhz was running 200uv I dialed it back just to make sure its not gonna wake lock on me even though it still might cuz my wake lock test didn't go beyond 3 seconds. Lol
[Epic 4G Android Development] Rodderik:
delete them from /system/media/video/shutdown/ and see
[Epic 4G Android Development] dchawk81:
Wouldn't that give me a black screen? As much as I don't like them, I do want something showing me my shutdown progress. Believe me, I thought about doing that way before you hooked us up with this kernel.

They only freeze when I UV too far so they aren't a huge problem.
[Epic 4G Android Development] Rodderik:
no actually you will get a box that says shutting down and the normal spinner things (with your last screen still in the background)...if you just wanted to test then rename the shutdown folder to shutdownold or something
[Epic 4G Android Development] dchawk81:
Oh well in that case I'll give it a try.
[Epic 4G Android Development] dchawk81:
Didn't seem to help like I thought it would. Oh well. I'm still keeping it off because I like this shutdown better.
[Epic 4G Android Development] Custodian:
Love how we run the same exact settings. And the 600 step is important as hell, it will not go beyond, 75 for nothing...im also blasting the 1200 step at 50...tried it at 75 for an hour or so and I froze all up. 50 is stable though..
[Epic 4G Android Development] herzzreh:
Is anyone getting an occasional failure to wake up? Battery pull is needed. This is hardly with any UV.
[Epic 4G Android Development] Custodian:
Can you post your settings
[Epic 4G Android Development] herzzreh:
k0nane's ROM, Genocide kernel, no UV, 100Mhz step disable, no overlclocking...
[Epic 4G Android Development] jbadboy2007:
Some are having wake lock issues with custom kernels syndicate has a kernel for it 1.0.4 and rod I believe is making one soon.
[Epic 4G Android Development] jbadboy2007:
I think its cuz rod said the 600 is not a stock frequency so that might have a lil bit to do with it. Maybe that step needs a lil refining in code somewhere so its no so tempermental. I might disable it all together.
[Epic 4G Android Development] herzzreh:
So I have to use one that comes with that ROM? Meh...
[Epic 4G Android Development] Custodian:
I can confirm that 600-400 ranges are important lower mid ranges, your browser, and other random apps operate in those ranges, especially quick boot. I have ran a series of tests to back this. And about 10mins ago I also tested quick boot reboot option with the 400 range uv at various levels, more importantly the 100-200 range. 400 uv @ 125 or lower the phone reboots fine. Any higher, I have to pull the battery. And also, while on the charger for some reason @ 125. The phone won't reboot, but off it, it will.
[Epic 4G Android Development] NetMedic:
I have never nad an issue runnimg any viper rolm. I have bren runnkng synergy on my epic and my girlfriends epic with no issues. I flashed the new 1.4 kernal and lost all of my apps and settings. Is this normal? I have read and read the OP and searched the thread but cant find any reference to the loss of appd and settings. Is this normal? I also got force close on most stock apps.

Are 2 great apps to back up your apps.

Also, it sounds like a terrible wipe. Berfore flashing any kernel, always wipe the dalvik cache twice. Recovery>advanced options>dalvik cache

Man this sucks. I can't undervolt anything more than -25 or I get freezes.

Hey guys I tried searching but this is a seriously hefty thread at this point, no one has mentioned it that I've seen but is there a problem with saving the boot settings? Mine comes up as an error.

[Epic 4G Android Development] vocaltreat:
Dang net...didn't have that prob....I had some force close issues but it was cuz of currupt data when it randomly rebooted one time...but that was fixed by reinstalling them....hit up chat and well see if we can get it figured out for ya :-)
[Epic 4G Android Development] burgerpimp07:
If that is the case, then shouldn't peoples idle battery drain be the same? All phones regardless of undervolts, should be draining the same standby? (assuming they have the same running apps/syncs in the background).
[Epic 4G Android Development] jbadboy2007:
Ill tell you this since I have gone further with my uv it makes my drain less in the area of when I get a text and am not by the phone and the screen on and tone play. I seen a 1% drain in 8 hours with 3g kinda amazing. Now I'm trying to get phone calls to use less battery. I think that's due to voodoo though running while on a call.
[Epic 4G Android Development] pauze10:
Forget Smartbench, you know what's my go-to stress test app now?

freakin Words With Friends.

After a few days of finding good undervolts, I thought I had a stable phone (benched several times, made calls, watched videos, browsed, etc.)

Last night I finally sit down to catch up on my days-old games and it's freeze city after a few minutes.

So now I'm back at square one, lowering voltage a step at a time and playing some WWF every so often to verify the UV is good.
[Epic 4G Android Development] squshy 7:
Not neccessarily, that last part you threw in there is the catch. Theres going to be some app/syncs that will engage the processor while the screen is off. While the percentage of cpu used during the time your screen is off should be mostly skewed towards deep sleep (assuming you dont have something keeping your phone from sleeping lol), its that little bit of time that the processor was used that you gain an advantage.

It might not seem like much, but that is dependent on what you run. For instance, I've been using system panel the past couple days. While it uses minimal resources, the resources it DOES use are now less battery consuming.

These things are hard to look at in black and white. If you were talking about two people who had ZERO apps or gapps, then yes, one undervolted and one not will probably get the same sleep life. But we know that is obviously not the case, and there are so many things that can eat a little processor time here and there that it shouldn't come as a surprise that our phones aren't in deep sleep state 100% of the time when off.

EDIT: BTW, ^^^^^^ all that was typed with the physical keyboard with impalers setting applied, and not one skipped key, only typos by user ;) freakin awesome

[Epic 4G Android Development] Anon9mouz:
So is that first step 100 and do u have a 600 step bc I been hearing people saying issues and try to delete or or get it to skip this step so I'm trying to see if I wanna leave setcpu and goto voltage control or what. I think I'm one of the only few that setcpu loves my phone hehe
[Epic 4G Android Development] theimpaler747:
I do have a 600 step.
[Epic 4G Android Development] Anon9mouz:
Ok I kinda figured that well ima try and see so I would want to step 1.3 the same as 1.4

I'd do them both at −25 to start.

Ok so I did all those settings and apply for now and it reboot my phone reset my launcher pro settings and idk if I just caused data corruption or what. Now idk if settings are applied bc of reboot but kinda seems a bit laggy but will try longer. O yeah also went from 50% battery to 12% after reboot
[Epic 4G Android Development] Custodian:
I just turned on the 1.1 step..uv at 100...my phone is smooth as heck now...guess battery will be better aswell :-) ......

100

100

100

75

125

175
[Epic 4G Android Development] theimpaler747:
That means you are too UVed if it rebooted and froze.

Glad it's working well for you :)
[Epic 4G Android Development] Anon9mouz:
Should I try same settings again to see if it works or start with something different. Why can't it just be simple like setcpu
[Epic 4G Android Development] theimpaler747:
No, lower it all. And it's not supposed to be simple, it takes work. If you don't think you can do it, I'd simply stop now.
[Epic 4G Android Development] Anon9mouz:
Lol ok I might use setcpu until I can sit down one day and actually mess with it. But me having journaling on is it harder for me to get data corruption if I get reboots like that?
[Epic 4G Android Development] theimpaler747:
With journaling on, there is no data corruption ;)
[Epic 4G Android Development] Anon9mouz:
O nice so then I can play around a lil bit hehe
[Epic 4G Android Development] theimpaler747:

Did 3 wipes on both cache's.
[Epic 4G Android Development] theimpaler747:
What problems are you trying to solve?
[Epic 4G Android Development] NetMedic:
My original post was 1433.

Short version(i thinkg)....running synergy since released and phone has been running like a dream. Not a single issue with anything. Bumped my wifes epic to synergy about a week ago and she to is having no issues and really loving her phone more now than before. Same with all viper roms.

I flashed Rodds new 1.4 kernal and after a really long reboot, I lost all apps that I installed from the market and almost all stock apps force close as soon as I click the icon for them and phone seemed kind of laggy. Rebooted three times just to be sure. Oh yeah, I also lost the actuall phone app so I couldn't make any calls.

I did this last week. I was also on call and my cell is vital to being on call so I didn't have time to really investigate. I had to odin back EB13 stock, then EC05 modem and then flashto synergy to get up and running again. I am going to try again this weekend and see what happens. The lost of apps was not a big deal. It was the loss of phone and f/c on all apps.

This is not me complaining or fauling the kernal. Just wondering if anyone else has had the same problems and what I might have done wrong. I did read the OP a few times and tried searching the thread but no lucl.

I'm running th latest Bonsai rom with Genocide of course. I used Voltage control to only select the 1000 Mhz and then only undervolted by 25mV. The phone requires a battery pull after the screen is turned off as it will not wake.
