It's just that the SGX540 is not close to being tested by benchmarks like neocore. The GPU IS frequency dependent, but in the case of those two EVO-appropriate benchmarks, our Epics can hit the frame rate cap with one arm and one leg tied behind its back.
[Epic 4G Android Development] juice.ki11z:
odin back to stock. so far stock it working with browser with no prob. so yeah im guess it the kernel and my phone they just dont get along.
[Epic 4G Android Development] BrianFX:
Regarding governors, I'm having significant choppy/laggy issues with the conservative governor (seems to be tied to wifi use). Appears as if though it's staying locked at 100mhz.

The ondemand governor is smooth sailing 100%. Is there a significant battery hit of running the ondemand governor vs conservative?

Great kernel all the way! Running at 1.4ghz vs 1.2ghz before, I didn't think I'd notice much of any difference. But there was a very noticeable performance boost running SNESoid and PCE.emu (TG-16). :D

Running Syndicate 1.1.0, 1.4ghz max, 100mhz min.
[Epic 4G Android Development] thomasskull666:
Tanimn and I have had a real struggle getting consertative to play nicely with our overclocking, so until it is fully operational I would suggest using the ondemand governor.
[Epic 4G Android Development] JohnCorleone:
Can you explain a little about the Voodoo Color. I swear the colors look more vibrant since I added this kernel and the battery isn't running hot at all running 1.4! Edit..battery settled in around 82 degrees at 200/1400 On Demand and the CPU gains are definitely noticeable. I am loving this. It added this really cool effect to Viper Pad. Previously if I used Viper Pad, the homescreen dimmed, now it fades all the way black making my shortcuts more visible. Great!

[Epic 4G Android Development] thomasskull666:
Just about to post the same link, thanks man!
[Epic 4G Android Development] JohnCorleone:
Thanks flyers....I knew my eyes weren't playing tricks on me. I probably should have Googled that question myself. Appreciate it as always
[Epic 4G Android Development] Tirregius:
Looking back to the first frozen ROM 1.0.0, I was getting some insane results from all benchmarks ...

1500/3400 smartbench 2010

2450 quadrant

@ 1200mhz.

Any insight you might be able to give as to why that rev. was so fast?
[Epic 4G Android Development] JohnCorleone:
Man, I think they were tricking tests then The correlating Bonsai had super high benchmarks too then next releases dropped scores..just my theory, not a fact. I had the 2450 area scores on Bonsai 3.0.1 then on Bonsai 4 they went to 1800-1900
[Epic 4G Android Development] thomasskull666:
No clue, I don't touch ROM business as that's all k0nane's neck of the woods. This question would best be asked in the rom thread.

Please keep in mind people that this is not a daily driver kernel YET, so issues are bound to arise. Most of them can be fixed by lowering the clock speed.

And one more time, if you want 1.2ghz rather than 1.3 go use Twilight Zone kernel :-)
[Epic 4G Android Development] JohnCorleone:
@thomasskull666..if this isn't a daily yet, I can't wait to see what you do next. IMO the color is so much better and the phone is much faster. If I need more battery, I will back it off some. I am not a huge game person so the FPS stuff doesn't really apply to me
[Epic 4G Android Development] thomasskull666:
The next few additions will help tremendously with day to day use, such as adding in BFS and fixing the conservative governor. There is also some really neat OC/UV stuff coming soon...
[Epic 4G Android Development] JohnCorleone:
Oh man, can't wait. I am more impressed with this kernel than I have been with some recent ROM releases. Lappy took a crappy so I can't click thanks 5x!
[Epic 4G Android Development] thomasskull666:
7K views in a little over a day, thanks everyone for taking interest!
[Epic 4G Android Development] theimpaler747:
This has 1.4 and voodoo color. ;)

No, don't flash genocide. Flash twilight.

I live the voodoo color and the 1.4, so there! :p

Can't wait for that! :D
[Epic 4G Android Development] bryanberlin:
I wonder how this would work on ext4 Midnight byor rom, any ideas?
[Epic 4G Android Development] theimpaler747:
Should work fine :D
[Epic 4G Android Development] relz:
I love the 1.3Ghz and voodoo color mod on this kernal, thanks a lot! Just curious, how come the color mod options don't show up in the voodoo control app?
[Epic 4G Android Development] theimpaler747:
Not tweakable with the app like sound :)
[Epic 4G Android Development] JohnCorleone:
I am running it on Midnight 5 EXT4 and its working great. Its more about if your phone handles the higher overclock
[Epic 4G Android Development] itisagoodname:
Absolutely no issues to report other than this Kernal is amazing.

Battery is <3%/hour without juice defender and my phone can run 1.4 all day long without an issue. I have it tuned back to 800 max while i test battery life and this this thing is still super fast.
[Epic 4G Android Development] thomasskull666:
Hey guys I was trying to release an update to this today but its looking like I won't be able to, but expect one either late tonight or tomorrow morning!
[Epic 4G Android Development] theimpaler747:
Bah! That won't do!!!! Lmao, take your time to make it right :)
[Epic 4G Android Development] sultan.of.swing:
1.4 is flying,2134 in quadrant but it does not feel as smooth as the twilight kernel to me.

There is a bit more studdering while scrolling in menus I think.
[Epic 4G Android Development] theimpaler747:
You need to let 1.4 warm up on some CPUs
[Epic 4G Android Development] thomasskull666:
+1
[Epic 4G Android Development] sultan.of.swing:
Well even on 1ghz it is still studdering quite a bit. Should I let the kernel set in for a few days?

I was using the 1.0.2 twilight kernel before and it was as smooth as silk.
[Epic 4G Android Development] theimpaler747:
Interesting, both have been smooth for me. Try wiping the dalvik from CWM.
[Epic 4G Android Development] thomasskull666:
The stuttering is just the cpu getting adjusted to the speed of the kernel. It may clear up, it may not but the only way to tell is to reboot a couple of times and just let it run. If it doesn't clear up, go flash to Twilight Zone 1.1.0 and see if it works better.
[Epic 4G Android Development] shigmata:
Been running this kernel since last night and its great. No probs at all wif it. Last night I was at 1.4 stable, saw smoke coming out of the speaker area. This morning I backed it down to 1.3 max 100 min, great battery. Oh that's wif an extended battery. Brings back memories of o/c my PII 400 back in the day, lol. Great work!!!
[Epic 4G Android Development] sultan.of.swing:
I wiped dalvik and cache before flashing.
[Epic 4G Android Development] theimpaler747:
Well humor me and do it again ;) Or as tom says, flash TW zone 1.1 and see if it's better
[Epic 4G Android Development] sultan.of.swing:
Im gonna let it set in tomorrow, the phone is silly fast at 1.4ghz. If I scroll slow enough the studdering isnt noticeable anyway, only when scrolling kinda fast.
[Epic 4G Android Development] sultan.of.swing:
No, not trying to start a kernel war ;)

Ill sit on it tonight and tomorrow, been on 1.4 ghz now for about 30 minutes plugged into the wall and no issues.
[Epic 4G Android Development] jct522:
Just flashed it and looks like its running good for me. Im on Midnight BYOR currently and have had no problems. I'm at 1400-200 onedemand. Phone is nice and cool and everything seems to be working good.

Thanks ACS!
[Epic 4G Android Development] thomasskull666:
Excellent, glad to hear it's working good for you!
[Epic 4G Android Development] s84471:
I was wondering the same thing.

Any idea if/when we'll be seeing color tweaks in settings somewhere?
[Epic 4G Android Development] k0nane:
Never, unless Supercurio implements them, or we do.
[Epic 4G Android Development] theimpaler747:
They're in the kernel's source, and from my understanding, are not all that tweakable... could be wrong, and if so, someone correct me please :p :D
[Epic 4G Android Development] thomasskull666:
No your spot on, the tweaking has already been done which is what the mod is. Not really anything else to modify unless you want to for some reason have your screen make weird colors lol
[Epic 4G Android Development] JohnCorleone:
Refresh...refresh...refresh. Man, can't wait for the update. I stayed awake all night last night putting the VisionKernel kindness through the paces.
[Epic 4G Android Development] k0nane:
By the way, congrats Thomas on a very successful first release. And thank you users, for supporting ACS and our kernel team!

Visit ACS's home at http://www.acsyndicate.net, and follow us on Twitter at @ACSyndicate!​
[Epic 4G Android Development] JohnCorleone:
Congratulations to Tom and Team ACS for pushing the envelope to the very edge and making it work!

so i get a freezing at 1.3 also, only when running intensive apps like n64 emulator. Flashed to SyndicateROM Frozen 1.1.0 which allowed me to run 1.4 for a while longer, but eventually crashed. what ROM is everyone running?
[Epic 4G Android Development] k0nane:
1.3 and 1.4ghz won't work on everyone's devices - ROM doesn't really matter. If it freezes up, that's why!
[Epic 4G Android Development] b15love:
got it..thx!
[Epic 4G Android Development] Tirregius:
I meant to post in the ROM thread. :-P.

I have no preference for 1.2ghz :-). This kernel is working perfectly for me and I love the mods you've baked in. I ran @ 200/1000 on ondemand all day today and from 330 to 7 with light use the battery went from 82% to79%!!! Less than 1% per hour. Killed the drm service this morning and used the recommended screen brightness widget @ 25% which is more than adequate. When I bought the phone I was ready to buy the big battery, now I feel like I have one. Unreal. Fantastic work.
[Epic 4G Android Development] theimpaler747:
Yup, just lower to 1.2 or below!
[Epic 4G Android Development] theimpaler747:
Glad you like the rom! :D
[Epic 4G Android Development] thomasskull666:
Thank you very much everyone, I really appreciate all of the nice comments being posted! Expect more great things coming soon ;-)
[Epic 4G Android Development] Esteway.619:
So I had a question. My friend has a vibrant and I know the have voodoo kernels but why do they have voodoo lag fix and what are really the difrence of that compered to the voodoo kernel we have here? Just wondering thanks in advance
[Epic 4G Android Development] k0nane:
The Voodoo lag fix is essentially EXT4 with journaling. It's unnecessary here.
[Epic 4G Android Development] Esteway.619:
Ohh ok thanks for the explination makes a lot of scense.
[Epic 4G Android Development] XxLostSoulxX:
When I scroll on the browser there's no lag nor studder and when I open the app drawer its so smooth and doesn't lag. Onlt time I have had it to lag was when the cpu gov was on conservative and I just opened locksxreen and quickly hit the app drawer.
[Epic 4G Android Development] ecooce:
This is what I've seen... I can't run 1.4ghz or 1.3ghz with this kernel,Quadrant and phone crashes at the planets (phone freezes after a couple minutes regardless); But with Twilight 1.1 at 1.3ghz and setcpu set at 1.3ghz performance,I can run all day no problem,tests and everything.

An3DBench score - 7307 with 200/1400 On Demand
[Epic 4G Android Development] compuw22c:
Thanks, I did see the source in the OP. Not to ask for too much hand-holding, but I was wondering if you could point me in the direction of the files containing voltage parameters it could help "teach this man to fish". I do know there are plenty of guides on how to build from source so I'm sure I could handle that (googling and reading) myself. If that's not something that can be quickly answered feel free to leave me to my own devices :)

Now to do my job, providing feedback. After 2 days of trying various techniques/roms, I could not get 1.3 to run reliably in "performance" mode (either performance governor or on demand with max/min both @1300) enough to keep it as a daily. So I'll be back down to 1.2 for now carefully watching this thread. Obviously this is because of my CPU not the great kernel work being done here, just trying to provide as much feedback as possible.
[Epic 4G Android Development] b15love:
I was about to post the same thing for twilight, takes 1.3ghz fine, but had higher FPS and benchmark scores with @ 1.3ghz with Vision (although unstable)..
[Epic 4G Android Development] JohnCorleone:
Is "user space" supposed to be faster than "performance" in SETCPU? The only way I could get the phone to freeze at 1400/1400 was with "user space" on Smartbench. I ran 1400/1400 "performance" for an hour and a half trying to lock it up but couldn't.
[Epic 4G Android Development] juice.ki11z:
has anyone got this working on STOCK SPRINT ROM with no problem??? using CWM 2.5xx?
[Epic 4G Android Development] rhyme187:
does this kernel support wired tether im running ACS' Latest RoM BTW
[Epic 4G Android Development] drizek:
People generally only use On Demand, Conservative or performance. I think if it works on performance, set it to conservative or on demand and you should be fine.

That said, try setting it to 1GHz or 1.2GHz on performance and see if that crashes it in smartbench
[Epic 4G Android Development] JohnCorleone:
I can't make it crash at all at 1400/1400, 1400/200, ,1000/200 on performance or on demand ..guess I am lucky there. I have had it 1400/200 on demand for 24 hours without a single issue. If I go to 100, that may be a different story
[Epic 4G Android Development] thomasskull666:
Unfortunately no, RNDIS support was removed for stability issues but it will hopefully be back with the next update.
[Epic 4G Android Development] dyehya:
I am just waiting for the dual-core unlocked kernel ;)

I think these voltages could use a little more tweaking at 1.3GHz or maybe using the same voltage for that level as tanimn's kernel as it seems more stable for people. Maybe look at an internal release with slightly modified voltages at 1.4 to see how they perform on multiple devices before release.

Regardless awesome work and hit me up in IRC. ~Cyc
[Epic 4G Android Development] caspertodd:
Has anyone tried playing a Divx file with this kernel? Mines seems to stutter quite a bit. I have SetCPU set at 100/1000, on demand. Conservative wouldn't even play at all. So far for me that is the only issue I have noticed.
[Epic 4G Android Development] JohnCorleone:
Are there any websites that use divx videos as their default so I can test this out?
[Epic 4G Android Development] WhiteWidows:
Is there any undervolting?
[Epic 4G Android Development] JungleJiujitsu:
So are you able to go on for more than 1 or 2 days w/o charging batt?
[Epic 4G Android Development] wizzlewizzle:
Someone asked me what wireless tether issue I was having.

When I try to start the wireless tether, the phone reboots. I have the profile set to samsung epic 4g.
[Epic 4G Android Development] JohnCorleone:
I believe its undervolted at 1000 like the other kernels. Nice avitar...
[Epic 4G Android Development] JohnCorleone:
That depends how you use your phone. I have been at 1400/200 on demand for a day and a half(yes on and off the charger). I have been messing with my Epic nonstop the past few days so I can't give real battery stats yet. I swear the battery seems as good as when I was running 1200...almost better but that can't be possible,can it? Lol
[Epic 4G Android Development] caspertodd:
Hmm, not that I know of. I have a movie collection (that I own) that I have in Divx format that I put on my sd card and am playing from.
[Epic 4G Android Development] JohnCorleone:
Did you try bumping up the minimum to 200? I only ask because you said conservative isn't working at all. Maybe the low end is a bit too low? Just something to try since I can't play a Divx at the moment myself. My phone handles 1400 but doesn't like 100 minimum very much.

My 1.4ghz Epic 4G
[Epic 4G Android Development] Custodian:
Hmm...while at 1.4 100 what are your symptoms? Im testing now and getting no errors so far...

Edit: just stressed tested @ 1400/1400....and hot damn!my cpu power level is over 9000!!!!
[Epic 4G Android Development] JohnCorleone:
Its not the 1400, its just that in the past my phone didn't wake from 100. I keep my daily setup at 1400/200 just to avoid the possibility of wake lockup. Now my friend can't get up to 1400 but never has issues running minimum of 100.

I think that was actually it! I changed to 200mhz min, and when I tested it did not stutter. I changed back to 100mhz min, and it stuttered quite a bit. Cool! Thanks!

Video Recording Issue

My phone seems to be stable at 1.3 and 1.4ghz but when recording video everything is out of sync meaning that the video does not record or play back smooth as the footage recorded is blurry when whatever being recorded is moved or moving...

If the video recording issue was fixed I would use this as the phone was super snappy!

I installed last night and tested out a few things and found that video recording was not working properly so I just Nandroided back to my backup and everything works just fine....

Any ideas?
[Epic 4G Android Development] JohnCorleone:
Well thomasskull said it takes a bit of time for the system to get up to speed when cranking it up to 1.4 so maybe it wasn't up to speed yet. You had me second guessing myself so I recorded a TV commercial at 720 resolution and it was fine. Could just be an oddity of going that high on overclock. I managed to get the screen to freeze for about 30 seconds while playing "3D pool" for a while but it fixed itself. I am by no means an expert but I am so fired up about an update that I am trying to help the dev out by answering some questions. His answers may be more complete and helpful. I am really pushing it trying to lock it up so I know what to do and what not to do. My mistake was having my hand on the back of the phone so battery didn't get any air through the bottom...lol
[Epic 4G Android Development] thomasskull666:
I definitely appreciate the help, my girl just left and so now its work time. Also in response to the post before the quoted one, video recording shouldn't be affected by overclocking but the refresh rate mod might be the culprit. I'll be releasing an update today that will set it back down to 56 until we can get it working properly. Currently trying to get documentation for the screen to see what needs to be done.
[Epic 4G Android Development] dyehya:
I don't have the link or whatever and can't remember what it was as I was really tired but I was watching a stream in Video Player and it broke the sound. I was using headphones. It started okay but a little bit into it the sound would go and I could hear the line "active" and little artifacts of sound and all of the system sound wouldn't work for awhile. I went into the Voodoo Control and uncheck and rechecked the default and closed the apps. Sometimes sound would come back to the system other times I would reboot the phone to get it to work. I don't know what could be causing this but it isn't just the video sound as it breaks all phone sounds once the glitch happens. Just thought I would let you know. Thanks again for a great kernel.

Also the new Juice Defender beta can now adjust the processing speed on it's own for better battery management :)

I keep having this problem with stock ec05 freezing when installing anything. Ive tried to install the latest ACSsyndacite rom and this kernel multiple times on RFS and EXT4 and it freezes at the sprint 4g logo. EVERY TIME no matter how many wipes. This sucks.....aparently my phone has had enough of custom roms and kernels. All I want is stock ec05 with a custom kernel to make it slightly faster. What gives?!?
[Epic 4G Android Development] theimpaler747:
Ummm.... don't wipe anything, try that.
[Epic 4G Android Development] carnivalrejectq:
Pretty sure i did that the first time before trying it with wiping. Same thing.
[Epic 4G Android Development] theimpaler747:
Can you flash any kernel?
[Epic 4G Android Development] carnivalrejectq:
havent tried any others just the tikaya (? lol) syndacite rom and this kernel.....really wasnt expecting it to hang like the rom did but i got the same results.
