It's just the default in the Linux kernel. 50% is the default for how much the kernel allows apps to overcommit a malloc, meaning that if there is say 1GB RAM available then it will allow an app to allocate 1.5GB. This is because apps often allocate more RAM than they actually use.

But, just to reiterate, this only matters if you have the overcommit_memory set to 2, meaning that you want to define manual overcommit values instead of letting the kernel use it's own heuristic to predict a reasonable limit (via overcommit_memory=0, this is the Linux default) or instead of setting the kernel to always allow any app to commit as much as it wants, unless it's an absurd value (via overcommit_memory=1, this is the Android default).

You can read a little more info about it here: https://www.kernel.org/doc/Documentation/vm/overcommit-accounting (Linux kernel docs) and here: https://android.googlesource.com/kernel/common/+/android-3.10/Documentation/sysctl/vm.txt#609 (Android kernel docs). You can read some really good info on this post at the IBM forums: https://developer.ibm.com/answers/q...s-the-impact-of-using-the-default-vmovercomm/

Note that Android's default of 1 is NOT recommended in Linux, and Linux default of 0 is NOT recommended in Android due to different design philosophies and behavior in memory management. 0 is used on systems with a dedicated swap partition and that are OK to get OOM errors, whereas 1 is used on systems that have their own memory managers like Android. This is one of the major differences between Android and Linux kernels. Consider the Android default of 1 as "defer to Android's LMK to manage memory commitment, it knows what it's doing", instead of Linux's "overcommit all the things! For SCIENCE!" interpretation of that option.

I honestly don't blame you, I only just recently discovered this myself - it seems practically nobody in the Android world has caught onto this lol. And yeah, those that did know probably just didn't care to share it.

This should of been covered in the XDA article on optimization myths, an article that cannot get enough coverage IMO.

Another interesting tidbit is that I discovered a very high zRAM amount on modern devices with low RAM but crazy CPU's, like my silly Helio X20 phone with 2GB RAM, is a REAL performance benefit. I'm talking 50% (1GB) zRAM here. The device actually runs faster and multitasks better on this workhorse CPU, and preliminary results show that it actually seems to *save* battery (difficult to quantify these things in real world scenarios though) possibly because the compression to/from RAM is less resource intensive than constantly reloading/recreating apps that are killed off during multitasking.

But I digress :)

Anyway, keep up the good work!
[Android Apps and Games] DB126:
Interesting you mention this. I read a similar testimonial elsewhere and questioned whether I was seeing some marginal benefit on a modest 1 GB device with an equally modest CPU. I suspect the difference was awash on that device due to mediocre processing power. It will be interesting to test on a different RAM starved gizmo with a bigger brain should one come my way. Thanks for sharing. :)

Do we have an answer for this issue yet? Running 6p with oreo
[Android Apps and Games] fitittome:
Core4 Locked

Using a Samsung S5 with LineageOS and Kernel Adiutor.

The kernel reports version number: 3.4.113-lineageos-gb3ae458 (latest for this model)

KA shows Core4(cpu3) locked at 2457Mhz

With Core4 (cpu3) locked at that I speed I don't see any problems except that it does not want to go offline either. Core2&3 (cpu1&2) are offline most of the time. Core1(cpu0) runs at 300Mhz for most of the time.

I had a look at the permissions and groups using ADB, they all look consistent (root mainly). One thing I did notice is that /sys/devices/system/cpu/cpu0/cpufreq is populated with these:-

affected_cpus

cpu_load

cpu_utilization

cpuinfo_cur_freq

cpuinfo_max_freq

cpuinfo_min_freq

cpuinfo_transition_latency

related_cpus

scaling_available_frequencies

scaling_available_governors

scaling_cur_freq

scaling_driver

scaling_governor

scaling_max_freq

scaling_min_freq

scaling_setspeed

stats

Whilst cpufreq is not defined for these cpus:-

/sys/devices/system/cpu/cpu1/cpufreq

/sys/devices/system/cpu/cpu2/cpufreq

/sys/devices/system/cpu/cpu3/cpufreq

When I load Kernel Adiutor that list in cpufreq seems to get populated for

cpu3 only

and does not appear to be removed when it Kernel Adiutor exits.

Can you point me for things to check?

How to save settings in this app bcoz it doesn't apply on boot
[Android Apps and Games] guest4711:
Did you set "apply on boot" for your selection? It may be hidden by the wheel on top of each card. You may test it using "settings - apply on boot - test".

And you may save your settings uding "profiles"...
[Android Apps and Games] gaurav247star:
Thanks
[Android Apps and Games] :
the answer is this app is broken on oreo and you are better off using a different app...

AFAIK, the dev hasn't responded or commented on this issue at all... i've seen many people ask here, there was a bug report/issue on github and i also commented to the dev on google play, no response...

I love this app, but Oreo has been out for months and it's still broken... I paid for this app too, but now I've had to switch to ex kernel manager....
[Android Apps and Games] lucastracq:
can you link this bug report/issue you are talking about? i can't find it...
[Android Apps and Games] :
https://github.com/Grarak/KernelAdiutor/issues/549

should've been pretty easy to find. it's the second issue down from his github's issues tab.... it looks like a couple of people have commented, but no reply from the Dev... although he has made a commit or two, since that issue was posted...

...like making sure the ads / donate shows up, if you try to use the app data sharing feature.... sigh.

anyway, the only thing that I miss the ex kernel manager doesn't have is custom controls... which would be great to have.... but at least it sees constant updates and supports a bunch of features that kernel Aduitor doesn't...
[Android Apps and Games] lucastracq:
but they say it's in nougat too. am i missing something?
[Android Apps and Games] colinlinton:
Do any other kernel managers have profiles that you can integrate with tasker? I use the kernel profiles to change the rgb settings for driving, sleeping, etc.
[Android Apps and Games] :
yes and no, they said it was in LineageOS (Nougat)...

i never had a problem with my Stock Pixel Rom for 7.1.1....

it could be that LOS was carrying a patch that now is in Oreo. but that's all speculation, even if very possible. I mean, i've/seen cases where the reverse is true. For example; OSMonitor worked fine on LOS, but didn't on Stock 7.x.x... in that case; for whatever reason LOS didn't apply a security feature from Nougat, so the app still worked properly...

anyway, regardless it is broken on Oreo, across the board, afaict, so LOS 7.1.1 doesn't really matter. the report was for Oreo.
[Android Apps and Games] :
I can't help u there. no idea...

that said; if you use KCal for changing RGB / post processing, technically - you could set those values without a kernel manager... they are accessible/in the file system.

you'd have to look up the location (maybe a thread on kcal in xda), then it's just a matter of tuning the handful of values u need in tasker and manage your settings from there...

Add s2s Gesture

Is there anyway to add sweep to sleep with this app to stock kernel of nexus 6p with android 8.1?
[Android Apps and Games] :
sweep2sleep is Part of the WAKE_GESTURES patch for the kernel. Just so you have a better understanding;

Apps can't add new features to the kernel; they can only utilize what is already available in a kernel. :)

Features like Advanced Color Management (Kcal), Wake gestures, USB Fast Charge, various io schedulers, etc - must be patched in and then compiled into the kernel. Unfortunately, Google doesn't add in a lot of extra sauce like that. So, you'll need to stick with stock or run a custom kernel for that kind of extra stuff.

[Android Apps and Games] :
that's because it's broken on oreo. none of your settings are being applied on boot because it crashes...

it's been mentioned throughout the thread... it used to be my favourite kernel manager; especially for it's custom controls... now I use exkm. sure, it isn't free ~ but at least it's actively developed...
[Android Apps and Games] jolinnard:
You can use latest version, Grarak fix boot for Oreo today ;)

https://github.com/Grarak/KernelAdiutor/commit/d02debf4c52992ef1e858736598b969d289d4fac
[Android Apps and Games] :
Thanks for pointing that out, but the dev not updating this for months left a bad taste in my mouth... Not only that - but I develop a kernel for the Google Pixel and at this point; EXKM is doing a much better job than KernelAdiutor at managing settings. ~

there are things that KA just does wrong, one Example being CPU-boost; it doesn't include all of the sysctls available && says input boosting is disabled on all cores, when it verifiably enabled on all cores....

Changing Colour/KCal settings is also dreadful in KA.... The only feature that I'm lacking is custom controls, but they aren't critical for me, just a nice thing to have... + they don't update properly either / are often wrong for some controls.

Maybe I'll revisit KA down the road - but for now, I use (and recommend) anyone using my kernel to get EKXM.

Good luck to the dev though and not knocking the app, but it just doesn't meet my requirements anymore.
[Android Apps and Games] jolinnard:
FYI Yeah, I was using EXKM in my shamu, but see the commit and just tried.... After compiling Grarak's KA still fails at boot. So no luck for now.

EDIT: My bad, it's not fixed with that commit.
[Android Apps and Games] :
Interesting, from looking atthe commit - i would've thought it was resolved now. Did you try the play store release?

Shouldn't make a difference, but you never know. lol.

I think KA definitely needs some TLC, i think. I hate working with/on Java / Android apps. Plus, I find android app development confusing. Ironically, I would rather work with linux kernel / C code ~ makes more sense to my brain. lol
[Android Apps and Games] jolinnard:
Yeah, sorry. It's not fixed:

[Android Apps and Games] :
Ouch, the fix didn't fix it ;)

Ya, i didn't even check / instal KA -> since I'm sticking with EXKM now.... I suppose I will periodically check in on KA development, if it starts to pick up.... because I do have a soft-spot for it - I used it for a longtime, donated, etc... But I gotta stick with what works.

Hi guys,

I wanted to change the max frequency of my cpu cores, but since then it used no frequencies above that anymore, but also stopped down scaling if there's no load.

It just stays all the time on the chosen max frequency.

After a reboot (and set on boot applied those settings again) the little cores scale fine between the lowest and set max frequency. But the big cores are still running just on the set max frequency.

I'm using a OnePlus3 with LineageOS 14.1

I saw that under /sys/devices/system/cpu/cpu%d/cpufreq/scaling_min_freq

The little cores (0,1) had the correct min frequency, but the big cores (2,3) had the same value as scaling_max_frequency. I tried changing it by hand, but it didn't work.

Anything I should capture into a log in a specific moment to help understand this?

Edit: found that using an other app, it set's fine for the little cores, but the big cores after reopen the app, it has for min the same set as for max freq.

So, maybe it's a problem with my rom? Reported in in my roms thread, too.

Merry Christmas,

L
[Android Apps and Games] iXaidyiu:

I uninstalled the app and installed a different kernel manager app and everything is working fine. Has anybody experienced this same problem? I set the toggle switch apply on reboot.
