I stick with boring ol' CM. I'm lazy, and the features of other ROMs don't justify the effort to move all my apps over. :p

Temperature does affect stability, though the thermal throttle (if enabled) should kick in before it becomes a problem. The AC was the easiest cooling method within reach. ;) I didn't check, but I'm sure it only reduces CPU temperature by a few degrees at the most.

The CPU voltage is an interesting observation. I'll give it a shot. I wonder if there's any leaked docs on the subject, since I haven't figured out a whole lot by digging through the kernel source.
[Sprint Samsung Galaxy S III] Joffie87:
Well, so far my cpu hasn't limited itself now, so I have no reason to make you a log. Typical right? I will be sure to upload one if the problem returns. I'm still getting odd issues with the gpu oc. Playing magic 2015, I get fc's, and shadowland will sometimes freeze, then go from landscape to portrait, then back to landscape, then go to the lock screen. Then I can unlock and resume play with no crash. The first kernel would just fc in that game, so I'm guessing you've had success with some of those changes.
[Sprint Samsung Galaxy S III] decimalman:
Yup, nothing stops a bug quite like actually wanting it to happen. :p I'm having the same problem with GPU OC: I'm trying to get it to crash so I can actually tell when I fix it, but it won't. :mad:

mudflap2.0 (and anyone else having trouble with 600 MHz): does this test build help at all? As an experiment, I added some logic to raise a few voltages that I suspect could be causing problems. The logic isn't very fancy since I don't know if it'll even work, so it might cause some extra battery drain.

Well, come Sunday my Galaxy S3 journey will end and the S4 one will begin. My mom's taking my upgrade for dropping my phone face first (instant screen death for any phone) & I get her S4. I'm gonna miss you, DKP. Thanks [MENTION=4932679]decimalman[/MENTION] for the best kernel I have ever used on the S3. I can only pray to Based God there's an S4 equivalent.
[Sprint Samsung Galaxy S III] Joffie87:
Ok, it locked up on me again. Here's a link to my log file on Google docs. I'm no expert but the only thing weird I saw had the words su and denied. Truthfully I didn't recognize anything else.

[Sprint Samsung Galaxy S III] decimalman:
Wow, there's some serious logspam coming from the video encoding stuff. I think I'll turn some of that off. It looks like it managed to completely wipe out anything interesting that might have been logged. :(

I'm not terribly familiar with SELinux, but those denials are probably just an app being denied root.
[Sprint Samsung Galaxy S III] decimalman:
Time for yet another GPU OC test build (AOSP-only, like usual). Changelog:

Disabled some logspam to make debugging easier

Disabled some of the GPU voltage logic (it shouldn't affect stability)

Tweaked the "interactive" GPU governor to make it less aggressive

EDIT: Oh, and Joffie87: I still haven't removed the extra debug information, so feel free to upgrade.

VM GSIII/jdsingle76's deodexed NDC 4.4.2/stock kernel ?
[Sprint Samsung Galaxy S III] mudflap2.0:
Yeah, now anything over 480 is unstable for dead trigger 2, and like normal My phone doesn't go over 1.89GHz, even at 1400mv, but who cares, at that clock everything would be unstable so right now at 1.78ghz,1400mv, and 480 on GPU is what I've been running without a hitch, as for before about running 600 flawlessly, it ran flawless for a day, then everything froze like before, so I run 480, if you could try smaller increases on GPU clocks like 480,500,533,550,580...etc that would be interesting to see, but what interests me is, what would you have to do to an s3 kernel to get 10,000 on quadrant and 20,000 on antutu?

---------- Post added at 12:46 AM ---------- Previous post was at 12:37 AM ----------

Well I'm testing right now to see of 600 is stable, don't know if you implemented this on the other test build or this one is special, but seems like best Bet so far

---------- Post added at 12:59 AM ---------- Previous post was at 12:46 AM ----------

Yep, doesn't cut it at all, same freezes, as for battery life, I'm the wrong person to ask, my phones always plugged in at the weekends and has 7000 mah on the weekday

To be more specific about the freezing try playing dead trigger 2 on tegra 4 settings(you can search tegra 4 graphics on any android device) and you will see e freezing I put up with [MENTION=1601421]600[/MENTION]mhz, not justdt2 but dt1, and many graphic intensive ones, now if you want I'll fricken show you the heatsink with aluminum foil held together by tape I have on my phone, in my attempt to over clock in front of the a/c on lowest temp on high, looks cool but puppy wouldn't let me slip by 1.91 at with 1400mv, this makes me sad, this is an ouya heatsink
[Sprint Samsung Galaxy S III] mudflap2.0:
Man; if only we had a dev like you in the nvidia shield forums; making a kernel this awesome. And. Continiued support for it too; now I don't know why; but for some reason I always want to flash back and forth from touchwiz; to aosp but don't know why I think its becuase I want all the integration and stuff that works on touchwiz; with all the modding goodness and up to date software and support for stock cm11. If youcould pretty please release a kernel for tw(4.4) that has gpu oc and bravia engine?

And I was research research Bing about people whonoptimized the isle(image signal prossesor) and made camera framerates better and video don't know how they did it but interesting; and a few more knickknacks knacks; how to turn off vsync in android? How to get brighter flash in camera? And lastly; how to boost audio and microphone performance/ quality?
[Sprint Samsung Galaxy S III] decimalman:
I grabbed DT1 and DT2 to test with. DT1 works fine for me, with max graphics and 600 MHz OC. DT2 isn't working for me at all (even without GPU OC, it freezes almost immediately), and I'm working on fixing it. Since I haven't had any issues with GPU OC itself, so I'm pretty much flying blind. I know it's a pain, but the only way I can make any improvements is to experiment and get your feedback on what works and what doesn't.

Clearly, the voltage stuff is causing problems, so I'll revert it. I'll try adding a couple extra frequencies, but I'm not sure how stable they'll be (certain frequencies don't work well with the GPU for no apparent reason).

You're not going to get 10k or 20k benchmarks with the S3's hardware, at least not without cheating. By today's standards, the S3 is a mid-range device, and no amount of overclocking and software optimization will change that. That said, there's still plenty of things that can be done to improve its performance and generally make it a nicer device. I can only handle one project at a time, though. :)
[Sprint Samsung Galaxy S III] decimalman:
Okay, I got DT2 working (at least, it's working as far as I've played), and I can't get it to crash my GPU either. Also, I tried adding a few extra frequencies, but they're not working well. :(

Since it's been a few days, let's do another (AOSP) test build. It's available as a direct download or on MediaFire. Off the top of my head, here's what's new:

Reverted the voltage stuff, since it's clearly causing problems.

Tweaks to GPU frequency scaling, and an overhaul to the "interactive" governor.

A handful of optimizations, cleanups, bugfixes, and an ugly hack to fix DT2.
[Sprint Samsung Galaxy S III] Joffie87:
I had my little sisters wedding the other day so I was too busy for testing, and I needed a stable kernel for the wedding. Going to give the new one a try though. Thanks for all your hard work.
[Sprint Samsung Galaxy S III] The~Skater~187:
So the process of trying the new test kernel today I had to random freezes. I ended up having to do a hard reboot to get phone going again. I'm going to play around and see if I can get it to freeze again so i can get you a log file. But thanks for the awesome update.

Edit: Update, I haven't had the freeze issue so far today. Been running fine all day. I'm starting to think it was just my phone settling into the new kernel. I'll keep you posted though.

I wonder can your phone suffer hardware failure and break from using another kernel or pusing it too high, I was lazy and on cm11nightly and on your expiremental kernel( only oc to1.6, and normal voltages no GPU oc or anything else), phone acts up and starts randomly rebooting, even with no apps installed, and even with the cm kernel, also I wiped the phone clean all wipes you can imagine on philz, then used nd8 tar, and for about 8 hours no problems, but after going home after rage quiting subway surfers, my phone freezes, and reboots, now I'm suspicious, everything is stock non rooted, so can this be a hardware issue?, so far its been 30or so minutes and no problem, so I don't know what would have couased that reboot on stock kernel and everything!
[Sprint Samsung Galaxy S III] avd:
Don't forget, the SGG3s are getting old. They don't have a 10 year design life. Maybe you are just seeing symptoms of old age.
[Sprint Samsung Galaxy S III] decimalman:
Switching kernels shouldn't cause any problems. In itself, pushing your phone too hard shouldn't cause any lasting problems either, but the heat your phone produces in the process could. You'd probably see major instability before the heat did any immediate damage, but it never hurts to be cautious.

Next time you're using a kernel that supports it, check what /proc/last_kmsg says after a random reboot. Towards the end, it'll usually give a reason for the reboot. There are plenty of fixable reasons for random reboots, even after returning to stock.

I promised a user I'd put out a new AOSP build today, so I guess I will. It's up on both mirrors.

Changelog:

Merged the latest commits from CM: Linux 3.4.104 and a fix for the BT headset issue

Built with a shiny new GCC 4.9 toolchain

Added a new, wildly experimental CPU governor that I've been playing with for a couple days*

Switched to 120 Hz timer frequency as an experiment

* The new governor is called "tierservative" because it's vaguely similar to conservative, except it uses frequency "tiers," and I'm not at all creative. :p It's nowhere near finished, but I expect good things from it in the future.

EDIT: Looks like MediaFire just took down the latest build, and I can't get it uploaded again. :mad:

[Sprint Samsung Galaxy S III] decimalman:
Great! I keep worrying that tierservative must have some major flaw that I haven't noticed yet. It's barely a week old and seems to do its job well, and that never happens. :p

Definitely post a report on tierservative's battery life. My (original, 2-year-old) battery is pretty temperamental these days, so I can't get a reliable impression.

Last time I checked, westwood worked the best in my area, though the difference wasn't very dramatic (maybe 5-10% better throughput? I don't really remember). I usually waffle between sioplus and bfq, though I'm not convinced that normal usage stresses them enough to make much difference.

Finally made the move to SlimKat and am enjoying using dkp kernel after WAY too long on the TW Rom. So far, the tierservative governor has been working well.

Love being back on this kernel.

Thanks for still being there for us.

I'm running the tierservative for the last 2 days {2 days prior for it to settle on, so 4 total} using the 7k ZeroLemon battery on heavy usage about 25% a day.. thats with 5 to 6 hours screen time.. workin nice
[Sprint Samsung Galaxy S III] wyelkins:
Tierservative ran great today with a lot of heavy use around town on LTE and various WiFi Hotspots. 3g and Bluetooth were good too. At "rest" there was very little battery use.

Runs great with AICP. I have had no lockups or reboots. I watched almost 2 hours of Netflix during my morning and afternoon commutes today using Bus WiFi. Downloaded Roms and listened to PocketCasts. Never a glitch.

I am sure it is a coincidence but my USB charging port started working again after being broken for several months. . It stopped working not long after I Odined to NDC. I have been running Wicked-X and Conquest Singularity ever since and have had to use wall chargers. I suspect that whatever lint is in there got moved around or fell out.

have been using tierservative for a while now with Slimkat 7.0. Working great. Great battery life. No issues that I have encountered.

Great job on the governor. Nice bell curve on the processor speeds. I am underclocking to 54 Mhz up to 1188 Mhz and I have a nice little bell curve on the processor speeds around 216/270 and then it tails off with negligible time above 702.

Great work!

[MENTION=4932679]decimalman[/MENTION]... I do have one thing to report... Was fooling around with some other stuff and looking at top during an adb shell session and I noticed a process uksmd which was using between 10% and 20% of the CPU consistently. That seemed awfully high to me so I did a little investigation and found that it was installed with a flash of the dkp kernel.

I even disconnected the adb and just ran terminal on the phone and top still reported it with the same amount of CPU as before. It is even asking for more CPU than top, which is kind of amazing.

What is that process? Should it be taking so much of the cpu?

Thanks.

I think it's time for a new build. I'm not 100% satisfied with the new changes to tierservative (battery usage has definitely increased), but a new build is way past due.

New AOSP build is up on both mirrors. Changelog:

Lots of changes to tierservative

Changed balanced performance profile (i.e. the default) to use tierservative

Feedback on the changes to tierservative is encouraged. They definitely increased battery usage a bit, but also smoothed out performance considerably.

I am running on SlimKat 7.0 and the new kernel killed my GPS and tethering on 7.0. Just to check, I clean flashed 7.21 and tethering seemed to work ok but GPS was still broken. Went back to Nandroid and got tethering and GPS back but after flashing the new kernel, GPS and tethering were broken again.
[Sprint Samsung Galaxy S III] involuntaryqool:
GPS broke for me as well
[Sprint Samsung Galaxy S III] decimalman:
Curious. I'm on CM, and GPS is working fine for me (I don't have anything handy to test tethering with, but it looks like it's working). Later tonight, I'll grab Slim and try to reproduce this. I have a hunch what's going on (I really didn't change much in this build, so there's only a few things it could be), and it should be a pretty easy fix.

Without details, this doesn't really tell me anything. techdog's post tells me a lot: how he's determined that dkp is causing the problems, how I can reproduce the problems myself, etc. That's the sort of information that I need in order to identify and fix bugs.
[Sprint Samsung Galaxy S III] techdog:
Ok. Let me know and I'll give it a test. I'm going to stay on 7.0 for awhile, just because I think it is more stable than 7.21, but I had the issue with 7.0 and 7.21.

GPS Failed on CM11 M9

[MENTION=4932679]decimalman[/MENTION]

I was having problems with the GPS as well on the latest build. I am on thr M9 snapshot of CM11 (not updating intentionally), and it seems that the latest build of the kernel causes the GPS to stop working. To check, I installed the kernel from 10/02, and it is able to lock onto sattelites without any issue.

I have been dirty flashing the kernels (only wiping cache/dalvik cache), so I switched between the original CM11 kernel, the 10/02 release, and the 10/30 release multiple times to verify. The 10/30 release seems to consistently have this issue, while the other two are perfectly fine.

Let me know if you need any logs and whatnot. dmesg didn't seem to reveal anything interesting, and the phone does heat up like normal with the GPS on when using the latest kernel, so I think the antenna is turning on but the resultant data is lost somewhere...

Nonetheless, thanks for the work on this kernel. It's definitely nicer than the CM one I've been using for ages. I undervolted quite easily after installation, and the tierservative governor is really nice - processor is nice and cool now! :good:
