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.

while I realize that many people hate benchmarks the truth in my humble opinion as a windows hacker and android enthusiast is that benchmarks, run properly, can tell you a whole lot. there is some variances but usually that is from screen brightness settings, running at different core temps, background apps, widgets, and waving the accelerometer around like you just don't care lol. and you can say all you want to synthetic means nothing but the fact is even manufacturer's use benchmarks in their testing of new chips as well. just look at the current benchmarks from sd 600 vs sd 800 from qualcom. so I have decided to carefully benchmark every kernel myself to find what gives ME the best user expieriance. maybe it will help the dev's, maybe not. maybe it will help you, maybe you hate my dog and want to skin my cat.
a benchmark can tell you how well the kernel makes use of the hardware so for testing purposes I have used stock rom on all tests. I have set up my cold box for testing so that the cpu and gpu do not suffer and return quickly to normal and have set brightness at 50. testing is done stationary against the back of the cold box proped so that cool air flows over the systemboard. for testing purposes there is only the stock clock widget and micro cpu monitor and a few battery temp/sytem stats apps running. after each benchmark the tablet memory was swept. all benchmarks were run 3 times and the highest score given is used here unless there was a wild varient and then it was tracked down and all benches ran again. after contemplating it i ran some of these plugged up to the ac on my cold box and sometimes i forgot to plug it up. and some using debugging but i honestly doubt that had an effect. so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
im also not really comparing custom kernels to one another but I do to stock kernel, every last one of them are great and offer a lot of features you cant get with stock. all offer performance above stock if the proper settings are used and the overclocks are not to extreme for the framework. they are all also still works in progress so I think they will improve with the developers attention as time goes by. i started with stock kernel and ran antutu, quadrant, velimo, 3d mark ice storm, 3d mark ice storm extreme, basemark x, gfxbench 2.7.0 t-rex hd onscreen, gfx 2.7 egypt hd onscreen
stock kernel
stock ran well and i liked it, but i hated having to long press wifi to toggle and short press takes you to settings, wtf google?
edit.... so at any rate my benches will probably be a little lower than yours on all these kernels as im running stuff to keep me informed in the background
whatever flo 002 kernel
the kernel ran smooth and i liked it. i have the same complaints about it as i do stock. wtf google?
so on this kernel as you can see it functioned better than stock on every single benchmark. some were close but just a little better is...well...better.
jassy release 5 kernel
this kernel is set up to use an external kernel control app. it will not function worth a hill of beans without it in my testing. and even further than that it seems to not like trickster mod for me as it bench's higher with faux kernel control app paid version. real world expierance is good. fauxclock is set to 1.89 ghz CPU OC. cpu ondemand governor. snake charmer and mpdecision on. intelithermal at 60 and 80 respectfully. gpu at 487. gpu simple governor. fiops i/o at 512 read ahead. as you can see in cpu and gpu performance it face smashes stock kernel then kicks it while its down and makes it cry for momma. i dont know what the dude pasted into this kernel but i like it. jassy worked hard so we could have a full featured kernel that works well. release 6 = win, release 5 o yeah baby performance even ondemand. i could still kick this to performance governor lol
elementalx 0.7 kernel
settings with no external kernel control app.
1988 cpu overclock on each core. 487 gpu overclock. simple gpu governor. stock bus. stock voltage. no stw, dtw. the kernel ran well in real world performance. STW and DTW are awsome features by the way and i really like this kernel but didnt install them for testing purposes, one less potential irritation. as you can see it actually lost a bit from stock performance though in every benchmark except basemarkx and gfxbench 2.7 t rex. that tells me there is a problem with cpu performance in this kernel. also look at the cpu vs gpu in antutu vs stock kernel. so what i like this kernel and with lower clocks, dude it rocks. stw and dtw are wins.
elementalx 0.7
settings with no external control app.
1890 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus.stock voltage. no stw, no dtw. again the kernel ran well in real world performance but as you can see it took a serious hit in performance at this cpu clock setting. the gpu features continue to score high though
elementalx 0.7 kernel
settings with no external kernel control app.
1728 cpu overclock on each core. 487 gpu overclock. ondemand governor. stock bus. stock voltage. no stw, dtw.
as usual really nice running and here the voltage values are more sane i guess. bested stock in every bench. i figure 1.9 ish before the poo poo hits the fan and performance benches go south rather than north. that seems about the same for the other kernels ive tested too. flar2 really has a winning kernel here with stw and dtw. highly recommend giving it a try
3flo v4 kernel
not testing this one yet as my boy doesn't even have the nexus 7 2013 but I tell ya, I got a good feeling about him. seems dedicated and excited.
Edit...he just got a mpdecision kernel booting and posting good scores but has a cores on touch problem for me. Very beta but it shows that even without a device you can build. Still got a good feeling about this one.
faux123 flo jb 4.3 001 kernel ulta
not coming. I can boot it and even run at highest settings but antutu ehh and im tired lol. maybe ill do it if the overclock structures are changed in some way but ehh not interested in this high on this chip.
faux123 flo jb 4.3 001 ES
settings. faux 123 kernel control paid version. 1.512 ghzcpu. mpdecision off. cpu governor ondemand. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400 and ondemand. fiops I/o 512 read ahead.
so here you can see again the same slight loss in gpu performance which lead to slightly lower scores than stock. cool kernel though and I do like intelli thermal so
faux123 flo jb 4.3 001 kernel mainline
settings in faux123 kernel control app paid version. 1.83 cpu OC. CPU Governor ondemand. intelliplug. mpdecision off. eco modeoff. snake charmer on. stock voltages. intelli thermal 60 and 80. gpu 400. gpu governor ondemand. fiops I/o 512 read ahead.
so I found the kernel smooth in real world. I looked for my sweet spot and found it around 1.836-1.89 cpu. above that didn't really work out well for me. so in this great kernel the cpu benchmarks higher than stock but for one reason or other the gpu seems to bench lower than stock. all in all a great kernel and omg I love the idea of eco mode and I think with proper cpu governor and eco this kernel would rock some battery butt.

Hi,
Is the cloudy kernel the best for pure performance in terms of lag? Not looking for battery or other performance enhancements.
Is cloudy kernel 1.5 the latest ( just to make sure i have a backup kernel to re-install just on case)?
Is the tweak on hidden menu for HIGH TEMPERATURE still relevant with these kernels?
I am running with ondemand governor.
And just to make sure:
- to install a new kernel i just boot to recovery and flash the kernel without any wipes, right?
- i have xposed and some G2 tweaks running, i don't need to disable/reset or anything?
Thanks for your help! I am still learning.
Nico.

Hello Nico.
I'm hoping that I can assist you with this topic.
First off, regarding the kernel you have plenty of choices. There are two, however, that I'd recommend.
1. Dorimanx Kernel. That kernel is absolutely amazing with LOTS of tweaks, thermal protection, ad-blocker, allows overclocking to 2.8Ghz and much much more. I can't list all the features because they are so many. But there's one thing in particular - it's fast. Dorimanx has created a hybrid kernel from 3.4.xxx and 3.10.y source codes. This is my go-to kernel.
2. Bruce Kernel. It's a modified stock kernel with Bruce's own tweaks. It's fast, very battery friendly but lacks customisation. It also doesn't have thermal protection or any thermal throttling.
Now to your other questions:
Yes, Cloudy 1.5 should be the latest.
I wouldn't mess with the ROM thermal protection found in hidden menu. The gain in speed is most likely negligible but you make your phone more prone to heat damage.
Ondemand governor is great for smoothness, but you'll have a ton of options if you decide to use dorimanx. I use alucard because it's the sweet spot between amazing battery performance and smoothness.
You can install a new kernel without any wipes. Kernel doesn't interfere with ROM as such and you don't have to disable anything. A Kernel is basically what makes software and hardware work together.
I hope this helps!

Thanks a lot for your answers, these are exactly what I was looking for.
I just flashed Dorimanx, and without knowing too much on how to tweak it (more on that later), it is really smooth. I am keeping it!

Thanks. Flashed perfectly, twice (I had trickster mod on and wasn't sure what it reset at boot, so uninstalled it and re-installed Dorimanx.)
Got 1040/2900 on geekbench even if that is not really what I care about. I had 950/2750 before, not that much noticeable difference in %.

OK, we're onto kernel tweaks , I have a few questions:
I discovered that I had STweaks installed, so let's use that.
1) Apart from governor alucard, what other settings should I apply? You mention thermal controls. I expect the defaults of STweaks are OK? If not, what should I do?
2) I found a GPU governor, should I do something there to have better performance?
3) my real goal is to achieve super smoothness when interacting with the phone, I don't play high CPU 3D games or anything like that. I want the phone to react instantly when I press somewhere or open something or press home or recent apps. Any advice? I modified touch boost frequency...
4) if I "reset settings to default" in STweaks, will it reset to Dorimanx' installed default as I just installed the kernel?
5) so that I don't bother anyone anymore, is there a manual about all these tweaks in Dorimanx/STweaks?
Thanks again so much!

Hey there. Thanks a lot for your answers, despite the thread being so old.
I actually learned a lot since i posted that
I use 2x intelliactive, 2x alucard, alicard HP, max freq 2.3, 2.3, 1.9, 1.9, gpu 100-533, i/0 read 1024, dirty tatios 5%/10%
Your settings look interesting, you sure you get great battery life? With 2 cores min? I am going to try
No mate, I said that's settings for u, u said u don't care about battery, so I tried to give u the best settings I can come up with for performance, I myself use 3 cores max, all 2,3 ghz 1 core boost, Alucard on-demand Alucard. 1024. 100 320 GPU. It's pretty smooth with art. But if I wouldn't care about battery, I would do the settings I told u. Hehe

no worries!
I learned to care more about battery I realized that it is really smooth anyway. I have a lot of SOT daily (movies, etc) and realized that using performance settings just drains too quickly and is not needed.
I do put animations to x0.5 (transition animation to OFF).
What I am really struggling with is home redraws... A bit better now, but they used to be 1000x times a day.
I would run with ART but it takes a lot more memory, and with my 16 GB I don't have enough memory left when running ART.
Buddy, I am on 16 too. I had 8.5 hours sot with art and cloudy 2.1!! I use nova launcher and I am happier with it can give it a try

I have a few very large apps (navigon, games,...) they take 2-3 GB.
I al so have movies, remaining is only 1.3 GB.
If i want to backup ROM i need to delete obb files, etc. With ART i will have nothing left!
Tried niva but didn't like it. Will try apex again maybe, but i really like the look of G3 home.
Hmm, I see. I didnt know that internal memory and has a thing to do ART, I just made it ART and everything was ok. Launcher is a matter of taste I guess. For lg launcher, I read that there are some hidden settings to lock it in RAM, so that it doesnt redraw that often, maybe u can take a look for that. Hope to share more information for better experience with our phones
@bloof I forgot to tell, I also like how g3 theme looks, and I use a g3 theme with my nova launcher. If pm me ur gmail, can send u my screenshots
I Need the Best gaming Lollipop Rom for I9505 with great performance and Battery life ?
That would be AOSP rom by the JDCTeam.
Make sure you set alucard kernel to the extreme performance or performance profile if you want better performance in gaming.

"great performance and Battery life ?" Performence or battery life! 5.1.1 CM with Alucard Kernel
if you get an alucard kernel in your rom then the raising the minimum clock speed to 810 khz on all four cores and the minimum for GPU speed to 200 khz it will help.
*gentle fair sleepers off
*arch power on
*CPU governors to ondemand or alucard with alucard hotplug
in developer option hardware overlays to off.
personally I think ktkernel was better with more options but you'd need to stick to AOSP 5.0 for that or lower
If he were to stick to older android versions (5.0 and lower) then he might aswell get KT kernel, which gives him the posibility of overclocking the CPU and GPU, something that is missing from the other kernels right now.
GPU overclocking isn't really stable, it actually takes away from the gaming experience.
How can increasing the GPU frequency, and therefor the performance, be bad?
If you overclock it too high of course it is unstable. But you should be able to take around 500 MHz easily.

I can't remember the steps you get in kt but I'm pretty sure the uppermost ones were next to unusable, 500 is only just above the standard speed.
the games are always going to have a fixed system requirement levels based on the hardware we have so there isn't that much to gain over optimisations for our roms I feel...
I always judge a rom based on how well it can play shadowgun deadzone. most untweakable kernel rom combos aren't so great fresh out of the box.
Well, I used KT kernel in the 5.0 days. I ran a gaming profile created by ktoonsez himself, which had GPU overclock, and ran stable all the way.
I usually judge a rom by how fast it opens the settings app. This presumes that the app was fully closed, otherwise it will just switch to it, wich is a lot faster than actually opening it. Also, animations are all off.
So, between the pressing of the icon and the actual opening of the app there will be a black screen (if animations are turned off). The longer you see that black screen, the slower the rom is.
So I installed Kernel Adiutor to tweak the I/O performance and was kinda curious about the governors and all. I noticed that all 4 cores stay on at ALL times. Is this normal behaviour? Why is there no hotplugging? could it be implemented in a custom kernel?
Coming from a Snapdragon 801 which had quad custom cores, it used to have hotplugging to save battery. Thanks for answering if anyone knows

My only guess here is probably the Developer haven't add support for the new'er Snapdragon chip/s?
Been using Kernel Auditor for awhile and I see sd820 reads as single cluster where should 2 (big-LITTLE) . Well just a thought
ok that makes sense, do you know of a kernel tweaker which is updated to work with the new snapdragons by any chance?
I found an app that works, for anybody who is interested, EX Kernel manager works great with the big.LITTLE cores on the s820, happy tweaking!
I'm currently trying out the Interactive governor tweaks posted around the forums
