Is there a way to have individual core Control - Nexus 7 Q&A, Help & Troubleshooting

Is there a way to have individual core Control clock speeds and governor if possible I'd prefer an app for obvious reasons (easier) I'm on cm10.1 5/9 nightlies

Some of the rate governors (not all of them) let you select the maximum number of cores allowed to be online. Depends on the kernel, but in principle you can use Trickster Mod. While clocking on the Tegra 3 is quite flexible, I believe it is not possible to have separate G cores operating simultaneously with different clock rates.

That's lame the subject came up because I have it working on my Atrix HD AT&T but I think I'll try another kernel

Extra battery but more speed with a kind of stepping stone per say look at it like this using my dual core 1.5 ghz atrix hd as an example
Sleep one core and you run single core with lots of lag
But with this method you can under clock core 0 1ghz to and change the government to interactive use the second core as something to the n7 companion core take it way down farther let's say 600mhz with on demand or possibly conservative governor. That way the second core would come on in times of lag for a small push to end lag spikes and like I said works on my atrix quite well

I think I would expect what you are describing to exhibit strange (pathological) behavior unless all of the rate governors are re-coded to collect their heuristics partitioned by processor thread affinity.
Does this also mean the 2nd processor is never off-lined? (They can drain a lot of juice even when underclocked due to static power dissipation issues, so it makes me wonder if the power savings is real)
Is the kernel development work for that device (Atrix HD) described anywhere by the implementer(s)?

A couple I couldn't point you to a definitive answer as I'm not a dev though it's defiantly someplace here on the forums even a kernel to look at

Are you talking about that script-ware by smokin1337? If so, it seems to (try to) work by forcing the second core to be on-line at all times, and then changing rate governors on a per cpu basis, not in the kernel but by continuously writing to each cpu entry in sysfs.
I peeked over in the Atrix HD forum and it seems it doesn't even have any working custom kernels yet...

@Franzferdinan51
Maybe you could throw me a bone - what exactly is it that you are using on your Atrix HD that does this? (Is it baked in to somebody's ROM, or a separate flashable patch)?
I *did* go searching over in the Atrix HD forum rather extensively.
Downloaded Codex01's "CM10.1PreformanceEnhancements-3.0.1" and looked in there - this doesn't do what you say.
Downloaded tcf38012's popcorn kernel and unpacked it and poked around - it also doesn't do what you say (lots of other tweaks tho).
Found a mention of something similar in posts by skeevydude. Downloaded smokin1337's "CPU Editor" for snapdragon - it was mentioned in passing in the Atrix CM 10.1 thread.
Am I just looking at the wrong things?
Anyway, everything that I've found so far that looks close to what you are describing writes control information to stuff in /sys/devices/system/cpu{/cpu0|/cpu1}/*
For what it is worth, that same (sysfs) stuff does exist in various N7 kernels - for instance, per-cpu entries for min/max frequencies and rate governors in /sys/devices/system/cpu/cpu{0|1|2|3}/cpufreq/.
So, maybe what I said first was wrong. Maybe the right answer should have been "kinda - maybe - sorta". I would have to understand the PLL schemes that different kernels use a lot better than I do to be definitive.
But I am still a bit skeptical that it actually produces the result that it claims - saving battery life by forcing two cores to be online at all times... without also affecting performance. And the part about two independent control loops affecting each other in pathological ways remains open as well (threads running on the other core with a different rate governor affect the measurement of the recent system load averages used by the second rate governor - and vice versa).
It would be useful to have a decent and repeatable way to benchmark interactivity - the first-person reports of "this is really smooth" or "lags badly" are always completely subjective and non-repeatable, so it is hard to know who to really believe when it comes to reports about this stuff.

What's the point of overclocking???

Ok I aint joking but seriously what is the point of overclocking a Desire z/G2. Unless I am running on a slow phone I don't see the point. Stock speed never lags and i haven't seen any difference between 1.5 ghz vs 800mhz.
The only time when 1.5ghz clock speed is useful is when i running quadrant and rubbing its scores infront of my friends face.
There is any areas where you can actually see the performance difference?
bluntly, if you dont see the point of it then you don't need it.
For others, sometimes you run alot of stuff in the background and still want to be able to have your main app perform at its best level.
There is also the minute tweaking of speed and snappiness of the interface. The idea of instant reaction when you open your message app, or your email, or anything.

Ya i know what overclocking is but I haven't found one instances where I needed it to run an app. G2 is already damn fast and it runs android with no lag but I really see no point until more demanding ver. of android come out.
I just wanted to see who overclocks their G2 everyday and for what purpose.

Fair question IMHO.
I don't see the difference when overclocking, or rather I don't feel it. Software does make a difference, but not the extra 200-500Mhz. I do feel however the battery drain
It always makes me laugh when somebody asks a legitimate question and you get silly responses like the above 2. It's as if these people feel threatened and have to justify that they are more knowledgeable than the op. The facts of the matter are most of the tweaks, mods and alterations are wholly unnecessary in the real world.
If you don't feel like it makes it better then you don't have to use it. I use it because I feel it makes everything just a little snappier and more instant. If you don't notice a difference that's fine. It's probably trivial for me to notice the little hang ups but I can't help it.

For me there's several reasons. For the most part, the reason for oc is because you can. But there are practical reasons as well. For example, with the stock ROM running at 800MHz, you're stuck with that. With an oc kernel and using SetCPU or built in clock settings in CM, you can adjust it as needed. Gonna play a game? Bump it up to 1GHz or so. Done with said game? Take it back down to 800MHz. But it's not all about oc. Sometimes there's a need to underclock. Getting low on battery and don't have a charger near by and need to squeeze another hour or two out of it? Maybe take it down to 768MHz or 600MHz (if you're running Pershoot's kernel).
Dungeon Defender:
800 mHz : not fun, laggy
1.5 gHz : fun, graphic are more smooth
Reasons for using over clocking:
Because I can
Because sometimes I do notice the difference in performance of the UI and some applications (wait for Sense 3.0 etc...)
Because I also use it to underclock.
Like everything else, a lot of it is perception. My wife cannot see any difference between our normal cable channels and the HD ones. I can (or am I just trying to convince myself that I can?). Oh well.
Finally some practical and helpful responses, showing an understanding of the need for information from some people.
here's my experience when it comes to overclocking. keep in mind that, like with your computer, it does vary from user to user... so I'm making these statements from MY experience, not making blanket statements regarding all of our devices:
- if you run multiple homescreens with multiple widgets and ui "smoothness," not just aesthetically, but performance-wise as well, is of concern, mild overclocking becomes necessary.
- if you have several apps running at any given time (in background or foreground) and ui smoothness, same definition as above, is of concern, mild overclocking becomes necessary.
- if you run any iteration of a sense rom in any configuration and ui smoothness is of concern, mild overclocking becomes necessary.
- if you run PSX/N64 emulators and you don't want audio distortion or general lagginess, more aggressive (in my case, 1209 is a safe speed for maximizing performance without having a drastic effect on battery life) overclocking becomes necessary.
on AOSP builds, especially gingerbread-based, I don't think there is a necessity for more processing power than what we get from the factory if you're running a relatively slim setup and aren't using something like a PSX/N64 emulator regularly.
I run mine at 1ghz, but I did use 1.2ghz before. I do notice a slight performance difference. Overall tho I don't notice it much. I notice it more when I'm doing multiple things.
Nonsense!

I run 1.1 because it is noticably faster. Everything opens faster and works smoother. My wife has a stock G2 and when I grab it to look something up on the web or to use maps when we're out, I instantly notice how mucher slower hers is.
Works for me so I use it.
I notice a definite performance boost on mine, but it also depends on which kernel/ROM you use. I was running meXroid for a few days and found that it got extremely laggy even overclocked with Flippy's kernel built in (1.9Ghz), plus my battery was dying faster than a Chuck Norris joke. PyroMod has always been reliable for me and I flashed back to 2.0 earlier and it's just as reliable and power-saving as ever.

Nexus 7 freezing

I don't know weather this is a bug in M-Kernel a38, but occasionally it keeps freezing:
CPU: 1.6 GHz - Performance
GPU: 468 MHz - Unknown Governor
Possible, but you should post this in the M-kernel thread, you could get your answer there. Weather is nice here
Derp, spelling.
Well of course it's going to freeze! You've overclocked it to 1.6 GHz. Not all devices are going to be stable at that frequency. You may be able to improve it by tweaking the voltages a bit.
And I would NOT use the performance governor for purposes other than testing, and especially not permanently. On m-kernel, it sets all four cores to max frequency no matter what. That's a great way to have horrible battery life and a hot device, with excessive processor wear. I don't really see why you would even need to use it.
Start by changing governor to touchdemand, and if that doesn't help, try adjusting voltages.

That observation only provides info about what your individual device is capable of; it provides no information at all about what clock rates another device will begin to fault at.
The fact that the EDP code in the stock kernel downclocks from 1.3 to 1.2 GHz when more than one of the G-cluster cores comes online is evidence that Nvidia observed some small fraction of Tegra30 devices that can barely operate safely with a single core running at 1.3 GHz. Otherwise, what would the point of that EDP code be - to willfully make their devices less competitive against other SoCs?
Running the performance rate governor for anything but short benchmarks is like trying to purposely shorten the operating lifetime of both the mobo and the battery.
I tried M-Kernel last week, and it constantly crashed when it was doing something.
Such as browsing Chrome/Youtube/Gmail.
M-Kernel just doesn't seem stable atm. Not only the crashes but also reboots with M-Kernel.
Before anyone says, I didn't overclock/undervolt anything, so its the kernel in general.
Went back to Faux kernel and not had a single crash.

The problem was not m-kernel. It's m-kernel in your configuration. I'm in that thread daily and flash every rev including the alphas. Are there are no reports of problems like this. The act of flashing Faux is probably what fixed your problem. Did you flash a ROM/GAPPS? All those apps you reported crashing are Google apps.

TricksterMod replacement

Do you know any good alternatives for TricksterMod that support OC and undervolting? I'm running latest ParanoidAndroid with M-kernel. Help much appreciated!
Why do you want to use another app? If you read OP of M-Kernel, you will see that only trickster is supported to change parameters. Extract from the OP: "The only app supported for changing any kernel parameters and settings is TricksterMod".
Odp: TricksterMod replacement
I want to try another one, because when I downclock to 1,2 Ghz, there seems to be no direct voltage change option for that frequency, closest is 1170 and 1230 Mhz. So I have no idea which one should I change.
That's the way the nexus 7 gets frequencies. Instead of using specific voltages, it uses an incremental table.
Sent from my Nexus 7 using xda app-developers app
Yep, i've read that tegra uses the table as a reference... Even if there the kernel has clock speeds that directly relate to the one you are going to use, -50mv does not mean a direct -50mv sent to the core. Also, tegra does auto 'cold zone' undervolt when it's capable. Hence, the voltage set contrasted to the frequence set in any software is relative to tegra but not 100% definitive...
Odp: TricksterMod replacement
Thanks, seems like undervolting my Nexus won't be as easy as I thought.
Dont worry too much about it. It's just like your local speed limit, if 40mph/kph you wont stay exactly at 40 all the time, neither always below or always above. It will be a reference and realtime decisions are made based on road conditions. Somewhat simillar here.
Im lucky to have a good chip, able to run at 1.6G with voltages meant for 1.2 stock... Able to push it lower but it starts locking up once in a while. It might take a few days so have fun! Remember to backup anything important just in case =>

S7 Edge Snapdragon Overclock

Hello,
Fairly new to the entire thing but I will get straight to it.
I have a SM-G935T Snapdragon in the USA, I am looking for a kernel for overclocking the device. At the moment what I have done is what I presume is a "lite" root custom on the stock 7.0 with supersu and Flashfire. I have tried using kernel adiutor and a few other apps that let you choose different settings but nothing seems to have any substantial effects on the benchmark scores.
As a note; the s7 edge is strictly dedicated to gaming purposes, I have debloated it and it has no SIM installed, it has a battery bank case and will spend most of its time plugged in or near a wall outlet, it is being treated as a mobile gaming platform. I have a Note3 specifically for taking with me as a phone.
With that said battery life is not a concerning factor I am looking for a decent overclocked kernel for the Snapdragon version, so far all I have seen is Exynos and stuff from other countries that don't match my 935t.
I'm likely overlooking something but any help would 've appreciated, doing it manually doesn't super interest me, I'm looking for a flash and go solution for this model that isn't going to trip app security searches.
Thanks!

I'm just going to preface things by saying benchmarks are not indicative of actual improved performance. There are numerous ways in which manufacturers can cheat benchmarks such that when you overclock you may not see improvements.
I'd suggest actually finding out if you overclocks through kernel auditor are actually working, download and run this to check if the cpu frequency maxes out at the one you set.
If the overclock is working as intended then the benchmarks are just not showing it due to other factors. More likely is that the overclock is not supported on your stock kernel so you'll need to flash a custom one with overclocking enabled,

I appreciate the reply, the issue is that none of the apps will actually go beyond the big cores 2.1ghz and the smalls 1.6ghz. My only options that I do have are basically enabling "performance" but the cores will still throttle even when Temps are 30c. What I'm saying is I have found nothing that has given me the freedom to actually attempt over clocking at all anyway and nothing will peak the cores as they say they should, even with supersu granted.
Hopefully that makes sense.
I took a screenshot of monitoring during a benchmark, so what's interesting is sometimes I get a 3D Mark Slingshot Extreme score of 2700ish and other times, more often than not, I get 1600 and looking at the graph, the cpu is up and down and all over the place like a bouncy castle in a birthday party but it's barely going over 1.2ghz on any core even during the cpu test and there is a massively noticeable difference even in benchmark and games. I have to restart the phome, wait for several minutes, clear the ram, wait a little more and then I might get a couple of good scores but I'm thrown right back into the bouncy castle throttling. I have a screenshot but I can't post it because I can't give links with less than 10 posts.
I've tried kernel editors, they don't stick anything and read false speeds, and the integrated performance mode seems to do nothing but make it brighter and change the resolution to 1440p.

I may be able to help with the latter. If you are able to flash xposed and install the Wanam Xposed toolkit you can disable DVFS controls, this should help with the throttling.
This applies for overclocking when playing games only.
There's an app made by Samsung itself called 'Game Tuner'. I've checked that when i run an app through game tuner the average cpu frequency is much higher than when i run it without game tuner. Also the device get noticably warmer with game tuner. So in my knowledge this is the only way you can overclock your s7 edge without rooting

I also tried pubg and yes, it's too damn laggy. lowering the resolution to 720p didn't help much. i guess i have to see how it runs on another device to be sure it's not a crappy app (Even though it looks like it)
I though the same thing, wish there was a easy way of lowering like on Samsung roms.

if you're willing to use the navbar (or mipop if you're on stock), it's as simple as making a couple of shell scripts that change density and resolution, then adding widgets for them. Since probably nobody is looking at the capacitive buttons bug this will probably be the only way to do it
The main problem for gpu intensive games is that they start to lag more the longer u play. Its because (at least on stock roms) the kernel throttles the cpu and gpu way too aggressively at a certain temperature. Same happens to hearthstone.
At beginning i can play a few rounds with 40-60fps, but after some time the kernel throttles the cpu and gpu down by alot even though the device itself only just got a bit warm. Main issue is throttling happens way too soon by way too much. And well some games are not well optimized and dont clear graphic cache often enough. Hearthstone for example has this issue, even if device is cooled, the game drops fps (not as much as with throttling tho) if too many graphical stuff loaded into the graphical ram over time (at least thats how i think it is)

I play PUBG on stock ROM after basically disabling CPU GPU thermal throttling and adjusting the governors to use the full frequency range accordingly. Having a fan of any sort, even a small usb powered one blowing air on the back up to a meter will keep the battery under around 50degC. The aluminum unibody cools effectively and efficiently with the help of a fan. I use a Tasker task to change the CPU limits and other optimizations before playing.
After eliminating the processor bottleneck the game can run on high settings smoothly. However the game uses 1GB of RAM on high settings that I've tested and the device lags under around 500Mb of free RAM on stock's OOM configuration. So free RAM needs to be able to reach at least 1.5Gb to not cause slow downs. Having already debloated and using greenify with and root commands to disable background user processes, I can play without RAM being an issue. I monitor free RAM and other hardware in real time to check these function without issue.
Having now removed both those bottlenecks I found there's still some lag that can develop after the phone has been playing for a few games or after standby overnight uptime. I've only just started testing changes to Virtual Memory thinking it might be a delay caused there. But the post quote above gave me the thought it could be GPU video memory related. Anyone know where to check in the kernel for how much RAM is reserved for GPU on the Axon 7?
I also gave the resolution lowering trick a little try and that didn't seem to improve performance at all. I'm still on B32.

Tbh thats quite an interesting thread for ppl that have either heating issues and want to lower voltages and edit throttling levels or for ppl that would like to have a more consistent performance when gaming. As you mentioned in that thread, i too renamed the 2 thermal config files with .bak at the end. Will test later to see the results.
But i think you could maybe update the thread with a guide for like:
-ppl that want to preserve battery life
-ppl that want to get more consistent performance
-and ppl that want to have a good mix between performance and battery life.
Also in that thread you mentioned disabling vdd restriction (like through kernel adiutor i guess). Is this necessary to really see the full effect of renaming the thermal engine files to .bak? I ask because i saw that inside the thermal engine files, there are also entries for vdd monitoring. So in the end would disabling vdd restriction actually do something? (Since the values from thermal engine files won't be applied at boot anymore after renaming them)

I get some lag even in Angry Birds 2, never had this on my Sony Xperia XZ Premium. The reason is due to throttling from over heating.
The phone does indeed get hot after some heavy gaming and this is when throttling starts and causing some lag.

That's some useful suggestions. For each point
- I've already shared that function. Just modify to a lower voltage you prefer. In terms of using it in combo with throttling disabled, that can be more advanced.
- Consistent like powerful? Need to tweak values in the file for full performance. Personally I've edited several profiles of various CPU GPU configs to range from light games to heavy executable from Tasker.
- Really a matter of preference. There isn't really a perfect middle ground. That's why vendors are offering power mode switches for normal use and gaming. Problem there is ZTE's is shipped broken and others still have decided limits. Which as my previous point, I use a basic profile for normal use and switch to suit based on the gaming demand. The method in that thread alone is inefficient as it's moderately powerful but isn't power saving for example.
Yeah I meant in a kernel configuration app like Adiutor. It's rather confusing but IIRC switching on VDD is it's own set of restriction different than unmodified. Removing the files by renaming .bak falls back to some hidden profile as described in that thread. Now I just edit the file for no limits instead and use Tasker to change parameters when needed.
I may post a guide. But I'm not sure how much interest or benefit there is. Hardcore tweakers aren't on stock, it's probably only a small group that prefer stock for particular reasons and are still advanced tweakers. One factor against AOSP though is I've heard repeatedly in the past the GPU driver gaming performance is lacking, don't know if that has changed. I'm all for helping out though, just unsure about useless effort. I welcome questions to get anything working and it's more direct than writing up a whole guide.

Well a guide might be useful for many users. Maybe also what your setup in tasker is.
Personally im usually not that into graphic intensive mobile games (except for like shadowgun legends, cool game imo).
I mean i play games while watching youtube or any series sometimes. But its still annoying when games start to lag after like 10 minutes already.
I also play hearthstone alot on my axon 7 since i used to play it alot on my laptop (sadly the game lags way too much now on my laptop due to weak hardware, hence why i play it on mobile now).
About the consistent performance i mentioned earlier, yes i meant as in powerful which keeps the performance without dropping down.
Sadly the performance governor isnt a big help since the aggressive throttling is still active, which makes the governor quite useless if it cant keep up the cpu clock at max.
Anyway, from what i noticed after renaming the 2 thermal files, shadowgun legends for example runs better for a longer period of time than before (it takes longer before the game starts to drop frames significantly)

With most GPU intensive apps and games like PUBG and Daydream View, I have to disable the Night Light. It provides a noticeable difference in performance.
@ Isopropil,
Hi,
Would you like to post your screenshot here? I experience the same problem and we probably help each other. My phone is A2017U, what about yours?
Thanks in advanceļ¼
Hope to hear you soon!
