What exactly do you see? Because no where does faux actually mention undervolting or that the kernel supports uv'ing nor is it mentioned in his change log. The only thing slightly related is a recommendation of the use of system tuner.

My bad its just at the top of this post for this kernel it says to use system tuner to do oc and uv so naturally one would assume that was stated because this kernel could do both... but apparently not. Np

Thanks

Frequencies do not stick on boot. I've tried SetCPU, Voltage Control, and System Tuner...all no go. I cleared caches and davlik before and after installation of kernal and even did a fix permissions after install for giggles. Still no go...Any app that stresses the CPU enough will change the settings. MC3, quadrant, antuntu, Nova3.....after running qudrant once and using my phone for a while it was getting unusually hot...I look at the settings and both min and max are set at MAX! :o

I can confirm that also, not that it bothers me cause i prefer 1.1 speed anyways, but even with version 13 there is still stutter in TouchWiz launcher, so i went back to version 9 and everything smooth again :) (so probably wont be updating kernels anymore)

I hope they get that kernel source for UVALH2 out soon...

I am running 13u on stock and LOVE it but the push notifications I gotta keep ignoring till the next day are annoying as hell...lol

I'll be glad when I can just run this kernel and allow the firmware push to happen.

Notifications are annoying...lol

Great work btw on the kernel....love love love it.... :)
[T-Mobile, Samsung Galaxy SIII] faux123:
It would be even nicer when people encounter issues with the newer base to post dmesg logs to help themselves. With logs maybe I can hax the current source to work with the newer base.. without logs, there IS NOTHING I can do...

If you want to help.

Do this...

Turn off wifi => turn on wifi => use terminal and type "su" followed by "dmesg > /sdcard/dmesg.log", save the output to a log and post here to help me debug this...

Remember, there is NO KERNEL SOURCE for the new base... THERE IS NOTHING I CAN DO WITHOUT LOGS OR SOURCE.... If you want to continue with my kernel, I would refrain from loading the OTA until source is available :( BLAME SAMSUNG/ATT/TMOBILE for WITHHOLDING the kernel sources even AFTER OTA update is official...

Thank u I was scurred.... by the way ... u archive 1.9 by fauxu ? Or r u just rounding up? What was the stock baseline before u UV'ed 1300? U can UV by more then -100Mv? If so that's amazing! It's up to the chip right?
[T-Mobile, Samsung Galaxy SIII] benefit14snake:
Yes using faux and actually it's 1.83 I thought it was 1.89 for some reason. Baseline was 1300 (if I remember correctly) and I can run 1175 with 100 percent stability. Yes it's up to the chip.

Below is what my UV are, if I go any lower I get lag and sometimes reboots or touchwiz restarts. It's possible that my wallpaper (live waterfall wallpaper) uses quite a bit of processing and memory so if I can't UV any more than what I have. Which is -75mV on all speeds at the moment.

I'm jealous of these -125 UV's .... I just hope 116 isn't too hot... is -75 descent for an UV at performance?

Options anyone? On temp and UV levels...

I want the -125 UV.... :'(

---------- Post added at 01:22 AM ---------- Previous post was at 01:20 AM ----------
[T-Mobile, Samsung Galaxy SIII] benefit14snake:
All under volts should be tested at full load for maximum stability.

Also to the guy with the. 75 under volt, it's hard to believe you have a completely linear voltage curve. Try lower voltage at lower frequencies.

I personally limit my cpu to the speed I'm testing and under volt from there. For instance, if you want to under volt 1.ghz stepping set you maximum clock speed to that and try under volting ONLY stepping below 1ghz. Run some stress tests and benchmarks to test stability and take it slowly. If you really want to under volt the testing alone should take a week or two.

If you under volt too many stepping too quickly it is hard to determine which one is too low. You will never get anywhere that way. Find the lowest at each level and go down from there.

Happy under volting!

[T-Mobile, Samsung Galaxy SIII] gordonzhao:
I just tried applying the same as Jerry's settings, before I could finish the phone crashed.
[T-Mobile, Samsung Galaxy SIII] benefit14snake:
Most definitely sir.

Thing is... Is a certain clock does a certain voltage then all clocks under Will do the same voltage. For instance, if 1.5ghz = 1150mv then 1.0 ghz uses the same if not less. This means if you work your way down the clock speeds, you do a lot less work. Usually about .025mv above reboot is good for stability (ymmv of course)

So if your system crashes at a certain voltage (which it usually will if you limit your clock speed to the one you are altering) then go. 025mv up from there and check stability.

Some of the lower frequencies kind of suck to test because they make your system lag but it is an awesome feeling to know your kernel is 100 percent tailored to your specific phone.
[T-Mobile, Samsung Galaxy SIII] s2556:
I am using mostly around the middle column but with some variations through out. On the lower end I use closer to Jerry's. Here are some screen shots of my recent set up. I've been changing them quite a bit though.
[T-Mobile, Samsung Galaxy SIII] gordonzhao:
You're using 13U then right? 13m is maxed at 1.6 whereas 13U is OC'ed to 1.8. I had to bump all mine up by 37.5mv from Jerry's settings. Wasn't stable, lagged every now and then even when just browsing through Facebook.

[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Hey Faux, in case you still need this dmesg output ive got 2 logs for you. I just updated to UVALH2 last night and just flashed your 13u kernel.

The first log I turned on wifi and left it alone for a min before turning off and getting the log.

The second I turned on then off as soon as it connected.

Dont know if you can use both but figured why not just in case.

Ive only been on it for a few but so far everythings going fine. Wifi does have to reconnect every few minutes it seems but otherwise has stayed active for me thus far.

If I can do anything else let me know.

Edit: just after posting I got a text msg and wifi dropped. It would see the network but just keep trying to connect over and over. I grabbed another dmesg right after it dropped and another after turning wifi off.

Dmesg3 is after wifi crashed and dmesg4 is after turning it off.

Turned wifi back on snd its acting as before where it keeps reconnecting every few minutes or so.

Hope these extra ones csn be useful to you.

I have a T-Mobile Galaxy S3 - Rooted - Stock Rom - Latest OTA Update

I love your kernel and I am having two main issues which you may not already be aware of.

1.) WiFi - It seems to constantly disconnect/reconnect.

2.) After the phone has been on for a few hours I will go to use it and I hit the power button to get to my lock screen, but the touch functionality on the screen is gone. I can't unlock the phone on the unlock screen and end up having to reboot.

Just wondering if this is because of the most recent OTA update?

3 times in the last two days my phone froze. The screen would flicker fast and I couldn't end task, had to pull out the battery all three times..

Once I was using my gps, once was in the browser. And once my phone was idle charging...

Should I re examine my undervolt settings?
[T-Mobile, Samsung Galaxy SIII] benefit14snake:
100 percent yes. If you followed directions it should be the last setting you changed . Up it .0125 mv and problems should subside.

Edit: it may be easier to hold power volume down and home button instead of pulling battery. I do it all the time when I Bork my kit.

CFS vs BFS

This may be a good read. You would have to digest this for use with the SGS3. I did some scheduling work a while back and you're right it would depend on your most common usage patterns. (Which probably aren't too much different than many of us).

Also, I skipped ahead in this thread so if there's a better answer floating around I'm sorry I missed it.

EDIT: After a little more reading on BFS I can quote this.

However

BFS was designed(Is being designed) to work well on systems with low numbers of cores and fewer processes (relative to desktops). Maybe I can find the code for BFS and CFS and run a simplified test to see which one might be better on the SGS3.

However, I think the best way to find out would be to script up a bunch or relevant tasks with a timer, and just switch the scheduler on your phone. Let me know if you want to give it a shot and want help with that. I won't install this kernel as I value stability over everything and my sgs3 is mission critical all the time.
