If the LITTLE processor is treated as normal processor, and this processor is slower, than I think that lags could be caused by migration of apps to this processor.

Reboots could be caused by kernel panic when there is no memory.

Don't know much about holo. Is it just a kernel?

I use 2 google accounts, nextcloud with dav calendar, contacts, tasks, sms sync, firefox, twitter, tapatalk, imap/smtp account. Mostly just google hangouts and e-mails, less frequently tapatalk, twitter, g+, some gps apps.

I flashed kernel HoloN_v6S7_MR2_KVM.zip and all problems I have are independent from "which kernel" issue. Clean NutOS kernel caused same problems.

Reboots are really rare - 3 so far noticed since I started using newest rom. Let's just first solve lags issue.
[ZenFone 2 Android Development] sheva_xan:
I have also experienced that. When I am sitting with the phone in my jeans pocket, the power button gets pressed, which in turn causes phone to reboot. Are you sure that it is not the case?
[ZenFone 2 Android Development] CapSel:
Sounds lame ;)

I never squize my phones in pocket. If pocket is ... to narrow I do not keep phone there.
[ZenFone 2 Android Development] SpiderPack:
Yeah... Sounds like it would make, but in my case won't. After a while (3 days without reboots) the 2nd BIG core starts being too idle. It'll only show 3% of usage. But once one little core is disabled, this one wakes up.

CapSel says exactly what I thought:

Trust me, I don't like suggesting "solutions" without certainty of what's the real problem... But at this point, I'm finding tweaks while the train is running, you know? lol

Sounds a bad idea, but LITTLE cores are less powerful (maybe less cache or were designed to be power efficient) and when I disabled one the lag went away!

At least give a try!
[ZenFone 2 Android Development] nutcasev1.5:
You do realize, that kamr invented big & little cores for our device right? ?

That they don't exist in real life, nor are any different from the eyes of Holo or anything else.

I will look into the cpu util thing. Maybe a good lead.
[ZenFone 2 Android Development] nutcasev1.5:
I didn't understand. So you have these problems on all kernels? Including stock? Why did you flash kvm?

The no memory theory does not work because android would kill non system apps if it goes there. Also, I would like the console ramoops or dmesg after such a reboot to diagnose for sure what is the problem.
[ZenFone 2 Android Development] jade01win:
I think if the phone is lag I just set min CPU to maximum until the phone is not lagy and set the minimum back to the default.... Coz I got that issue too but that issue , I got on groovy android rom with holo kernel , but after move to NutOS that issue is gone.... And playing game more smoothly like PUBG Mobile running more smoothly.... Thanks NutOS haha ?
[ZenFone 2 Android Development] jade01win:
And I got this too ?
[ZenFone 2 Android Development] CapSel:
I started using different kernels just to experiment. Latest installation of holo kernel was to find out if kernel is the problem. Its not.

Lags has stopped for me. No reboots yet.

I have 1000 of zram, 100% swappiness, 100% overcommit ratio, "big" core set with interactive governor, freq 250 - 2000 Hz, "LITTLE" set with ondemand governor, freq 583 - 2500 Hz.

Seems that all processes are migrated to second core whatever is set on governor and min max freqs for any of them. first core stays iddle most of the time. I didn't want to disable any core so I tried to emulate "big.LITTLE" tech by switching schedulers and frequency.

edit:

Phone started lagging again. It took more time than before and its not as intensive as was before these settings.
[ZenFone 2 Android Development] methuselah:
People always crying regarding lags here. The thing is remember, it's just a 2 GB ram device. I have installed nut's kernel on my asus, and my nephew is using it. He also play games. I never had any issues. This device holds a atom professor. I mean common it was Intel's first take on mobiles. This professor still give me more on an average Qualcomm processors. Just make sure once in a month or 15 days you guys dirty flash ROM and every night give decide a reboot. I prefered in the morning. This device has already outlived it's life. Either buy new device or stay with the fact it's just a 2 gb ran device. But the thing is you should not tweak kernel settings. The dev already here did so much testing. I tried to do mess with the kernel, it certainly helped with lags but at the cost of battery. So I can live with lags for a while. It matters for what issue I ping the dev. ?
[ZenFone 2 Android Development] nutcasev1.5:
Thanks methusala but other kernels don't lag on the 2g devices so it's a software problem with Holo.

( btw where can i find this professor who hands out Processors? Can you get me one ??? )

Now! Let me make it clear. The lags are not because of a performance derp. Or a bad configuration. The code is fundamentally flawed. There is no way around it. If you use the kernel & get lags, you will get lags no matter what you change.

It's the Linux kernel updates from 2015 that are the issue. They were not done properly, I stupidly just picked them from old kernels like flare. Now when I cross verified, they didn't have vital changes & skipped a lot of stuff & had new changes that were not there in the original updates. Absolute mess. So, I started again. Right now testing 3.10.82, in about 10 days I can get everything running fine.
[ZenFone 2 Android Development] CapSel:
My device has 4G of ram and I experience lags.
[ZenFone 2 Android Development] Arerive:
same for me. now i just use it without profiles for now.
[ZenFone 2 Android Development] nutcasev1.5:
[MENTION=5439285]Druboo666[/MENTION] Could you please search & point me to the fonts fix for oms. The sepolicy change you talked about?

Also, 3.10.92 in testing now.
[ZenFone 2 Android Development] alphaprosper12:
Me too
[ZenFone 2 Android Development] okicupu:
Hai, can you give me tutorial? This lags so annoying me so well :eek:
[ZenFone 2 Android Development] LSS4181:
Is anyone having issues with SIM card detection? I did read a few posts and they mention about hardware related causes, but I don't think it's 100% hardware related.

For some reason recent ROMs couldn't properly initialize the SIM cards at boot. The SIM cards are there and I could use some apps to read their information (at least for SIM 1), but it just says "No Service" and the SIM Cards settings pane says "SIM empty". From the Phone Test menu accessible via *#*#4636#*#*, the SIM status (data connection) read "Disconnected", but its information were all there.

It's not just NutOS, I'm having the issue with every recent ROM and regardless of kernel. The situation was a bit better with GA, but the SIM cards were initialized late, as I see the select SIM card menu every boot which shouldn't be the case.

I'm able to force a reinitialization by reinserting the SIM (it then becomes "No Service - No SIM card" then shows the carrier name and such after a few secs), but it turned out I may need to repeat this procedure every boot, and I may have to reconfigure which SIM card to use for cellular data, calls, SMS, etc.
[ZenFone 2 Android Development] kenbo111:
Have you tried shimming the sim card with a piece of paper. They are notoriously loose on this phone.
[ZenFone 2 Android Development] LSS4181:
I know about that, but I don't think mine is that loose, as I haven't recorded any cases when the SIM card would lose connection halfway while running. It only happens right after boot, and it only happened recently with recent ROMs. The SIM cards were picked up by the system but the phone was not initializing them properly until I reinsert them (even though the system says No Service or SIM slots empty, I could still find my phone numbers, IMSI, everything about the SIM cards).
[ZenFone 2 Android Development] Azmaluth:
Hi guys, sorry to ask, in case it had already been asked, but dow this rom work on the zenfone zoom? The Z00XS to be precise. Thanks!
[ZenFone 2 Android Development] YudhaNoob99:
Can you give Music & omniswitch zip link please?
[ZenFone 2 Android Development] nutcasev1.5:
Quite simply, no

You mean the lineage music player? Also, omniswitch?

Have you read the OP?
[ZenFone 2 Android Development] YudhaNoob99:
Yes I have read. In your lineage apps not contain eleven player and omni switch
[ZenFone 2 Android Development] deksman2:
With respect, mine has 4GB RAM, and I still experience lags on NutOS.

GroovyAndroid though for some reason is absent of lags and works fine on my Zenfone 2 (Z00A).

I experimented with other kernels on NutOS, and they don't seem to have any effect on lags though - the problem lies elsewhere (possibly in how the ROM is configured).

Also, this phone is not exactly 'outdated'.

It has rather powerful hardware inside and 4GB of RAM (at least mine does).

I've had it for nearly 2 and a half years now, and I don't intend on changing it just yet (maybe in another year or so when RAM and hardware in phones improve and 5G support comes out?).

Right now, the phone runs pretty good, and I think this particular ROM simply needs adjusting to other versions of Zenfone 2.
[ZenFone 2 Android Development] YudhaNoob99:
I have download lineage suite, but when flash is done. All apk is force stopped.

I downloaded again with mini zip and reflash, flash is done but after reboot no apk already installed _-
[ZenFone 2 Android Development] Luq4dmin:
Since when default lineage got omniswitch ? I think only RR got it n other heavy customized roms...
[ZenFone 2 Android Development] CapSel:
It seems that load of cpus or memory usage or even speed of gpu does not have anything to do with lags. Seems like just fps slows down with uptime.
[ZenFone 2 Android Development] YudhaNoob99:
Can u backup your eleven music apk please :(
[ZenFone 2 Android Development] nutcasev1.5:
Why? It's included in the rom by default. You are definetly doing something wrong during the flash. No one has the fcs you are talking about.
[ZenFone 2 Android Development] YudhaNoob99:
I try to dirty flash your suite too but the apk still force close. Why nut os zip not contain basic apk like eleven calendar and gallery:(
[ZenFone 2 Android Development] CapSel:
[MENTION=7074010]nutcasev1.5[/MENTION] could you make a rom with -O2 switch whenever gcc is used? I'v heard at some C++ conference a comment that gcc often (very often) produces faster code than with -O3. clang has no problems with it.

Is there a way of selecting cpu scheduler (not freq governor)?
[ZenFone 2 Android Development] nutcasev1.5:
Because most people disable them anyway & install what they like. Did you flash gapps? Are you flashing in the right order? Did you do a clean flash when you moved to NutOS? You need to flash the rom 042118 version, the apps zip you want, latest gapps; even on a dirty flash to update.

Then wipe cache & dalvik & reboot.

Please, a link, because by definition O3 is supposed to be faster than O2 & here we use effectively Ofast, which goes beyond O3.

I have observed in practice with both NutOS & Holo the same trend.

There is nothing to select for us as far as I know. Only HMP socs use a thread migration scheduler. Let me know if there is something like that in the Linux 3.10 kernel, because I don't know anything about this. Maybe, do you mean the thread execution scheduling? In which case it is handled by the scheduler framework, which you can tune using the sysctl terminal command on android.
[ZenFone 2 Android Development] CapSel:
Seems to better describe situation with gcc:

https://stackoverflow.com/questions/11546075/is-optimisation-level-o3-dangerous-in-g

I was asking for -O2 or -Os just to check if it makes any difference.

Do you have maybe some kind of instruction how to compile ROM? I could try to setup compile host in docker...
[ZenFone 2 Android Development] nutcasev1.5:
The thread you linked to was from 2013, I was pleasantly surprised that even then most of the answers say that if your code is fine O3 won't cause issues.

For the one answer which caused a drop in performance, it was due to cache missing in the fast memory of the processor. I already have a change in my kernel to prevent that.

The gcc used to build Holo, 7.3.1 was released by Linaro 2 weeks ago. The rest of the rom is built with Google 4.9 which is about an year old. By default, every rom I have come across uses O2, with the exception of Bliss.

When I was working on the first builds of NutOS implementing Ofast for gcc & O3 for clang gave a better result & I don't see any reason why that would change now.

ROM development is to hard to explain here. If you are interested, pm me here & we will continue on telegram.

Thanks for your interest. The lag problem seems to be gone in the kernel betas I recently released for the testers.
[ZenFone 2 Android Development] Blackdragonbird:
Hi, I read in this thread some time ago that this rom was going to receive the Marshmallow GPU driver. It is true and have happened already?:D

I'm having graphical corruption in some games in another Nougat ROMs, issues that vanish in Marshmallow ROMs, but M ROMs have issues with multitasking, that N ROMs don't have, and I need multitasking for my use with games in the phone.:(
[ZenFone 2 Android Development] abutrex:
Any news regarding the Oreo ROM? I'm super excited for that
[ZenFone 2 Android Development] CapSel:
wrong thread
[ZenFone 2 Android Development] nutcasev1.5:
It's been shelved. My collaborator on it is offline & not responding. That is bernardobas. He's unreachable. So no work going on over there right now.

If you are referring to that 'Hope Thread' that thread has only given you hope so far. Not even a Lineage 14 build, which can be made within 2 days even on a very slow setup.

I'm very skeptical that the thread will go anywhere.
[ZenFone 2 Android Development] septimvs80:
IMO upgrading kernel to 4.4 would be far more useful and important than Oreo. Phone would be safer and easy to patch until 2022. Security and longevity are more important than feature gimmicks.
[ZenFone 2 Android Development] nutcasev1.5:
Useful things come hard. Turns out to do the update would take a team of dedicated devs as you would have to completely rewrite the device specific drivers to work with 4.4

The difference between 3.10 & 4.4 is about 250000 commits, most of them, I would say, breaking our drivers.
[ZenFone 2 Android Development] :
3.10 is enough for mee... Just for MAGISK ;)

And what about Oreo? Is it harder?
[ZenFone 2 Android Development] nutcasev1.5:
Hard things are not impossible. But alone, achieving them isn't worth it.

I have said many times that I can't do this alone. But alone is what I am. No other devs are around to help me really. That's why Oreo is basically impossible & for the same reason 4.4 is as well.

A fair amount of my testers are facing hardware trouble. Emmc dying, loose sim card ports, degrading batteries.

After all this, not much reason is there to continue developing for such an old phone. I'll keep maintaining my work, that is the kernels & NutOS, as long as I use the device but I just don't find any reason to keep going.

MM blobs is a good way to say goodbye to Android development for me. I'll move onto actual hardware development after that.
[ZenFone 2 Android Development] jade01win:
Can anyone tell me about if my phone battery under 20% , my phone suddenly off??
[ZenFone 2 Android Development] Shredinger22:
Omg, Pixel launcher animation on this rom is so laggy and not smooth... Am i only one with this issue?
[ZenFone 2 Android Development] DeadrosesDR:
What lineage appsuite have you installed? The full one or the mini one? I have performance issuse with the full one. Takes about 20-25 seconds to install KAM and everything else was just a laggy mess and pixel launcher really laggy

While mini one took only 5 seconds to install KAM and everything else is super duper smooooothhhhh

I am not entirely sure if its the app suites tho but this is what ive experienced
[ZenFone 2 Android Development] HugoClaw:
Don't know what the problem might be, for me everything went smooth with full lineage appsuite. Was it a clean flash ?

P.S - Just tested pixel and it is working just fine for me
[ZenFone 2 Android Development] DeadrosesDR:
Clean flash yes:D

That's good to hear! May i know your Twrp version?
[ZenFone 2 Android Development] JBolho:
I use updated TWRP for a long time now, no issues with rom.

When installing this rom, PLEASE, do a clean install. And by clean install I mean wipe:

Cache

Dalvik/art cache

System

Data

And if possible, internal memory.

This is to be sure that there are no residual conflicts to mess up the functionality.

Secondly, don't mess with file systems, keep everything ext4 (which is the default for this device)

Installation should be in this order:

1 - Rom

2 - Lineage Apps

3 - Gapps (use OpenGapos x86 7.1 nano)

Myself and others have been testing this for weeks / months to get to this point.

I'm personally running this rom, every day, with Bluetooth, Location, Sync, Android Wear.

I use the full Lineage App suite and the Pixel Launcher.

All these things have been tested and tried, on different ZF2s, with zero issues. UX performance on Antutu is better than a Nexus 6 running 7.1.1, I **** you not.

After first boot, ART runtime will take time to build and optimize the cache on the background, so it's possible to feel minor stutters/lag on the first hour or two.

There are no major lags, even less with Pixel Launcher, and if you encounter this issue, sorry, you are doing something wrong.

Follow these recommendations, and you will be fine.

P.S.: Do not restore apps / files / whatever from other roms with Titanium or similar apps. Do everything from scratch.
[ZenFone 2 Android Development] Domanshi:
Is there a problem with running it on f2fs? Coz I am since I forgot to change it back. Haven't run into issues so far but maybe it affects something else?
[ZenFone 2 Android Development] JBolho:
F2FS has notoriously worse performance on our device. Use ext4.
[ZenFone 2 Android Development] Domanshi:
Oh I see. I'll clean flash again. Thanks.
[ZenFone 2 Android Development] nutcasev1.5:
Keep running it.

Let him test it there.
[ZenFone 2 Android Development] fish_pudding:
running f2fs wif battery profile no serious lags juz small.small stutters here and there battery is nt tat good
[ZenFone 2 Android Development] Domanshi:
Unfortunately, I have just clean flashed it to ext4 system. But regarding running it on f2fs, I had no problem whatsoever. There were some lag here and there, but I guess it's mostly due to the apps running on my phone.

I am not sure:D i installed mine in this order

Rom>gapps>mini app

No lag whatsoever at first boot, app installations fast af and really good stable gaming performance(heroes evolved on High settings)

Its supposed to be laggy at first, maybe im doing something wrong?:/
[ZenFone 2 Android Development] filipe_m:
Hi...

Today I will flash this rom...

But appreciated if first someone could explain to me the advantages of installing lineage app suite or the problems of not install.

Thanks for your work!!
[ZenFone 2 Android Development] ashish.ramani:
The rom is made with least required apps. Totally debloated. So the Lineage apps are to provide any extra apps required. Flashing only the rom will give basic functionality apps.

[ZenFone 2 Android Development] nutcasev1.5:
Define ditching. I won't work to include new features or spend much time. But as long as I have the physical device in working condition I'll keep making maintenance updates.

But no new features or the kind. No oreo or 4.4. I won't develop new things anymore.

Is anyone having stability issues with this rom for some reason when im browsing the web the screen presses random places by it self.I dont think its the screen as sometimes it works properly sometimes it doesn't Also im using your custom kernel battery profile i don't know if this is the cause or not.
[ZenFone 2 Android Development] methuselah:
This issue I guess with the faulty display. When display heats up this issue arises. I also use to had this issue. But now the thing is I am not really sure about this thing. Rebootseems to fix sometimes this for me .
[ZenFone 2 Android Development] 4242hanspeter4242:
Im using this rom since 2 days now and I must admit that this rom is great! I did compared Benchmarks with my brothers zenfone with official Android M and while his GPU score was around 6k my score was 9k. So basically its a huge GPU improvement.

Also my picture quality from the camera improved alot over Android L.

Overall its pretty stabile. Battery life seems pretty ok.

The only bug i met so far is, that after taking the picture when u tap in the taken picture u cant watch at the picture in landscape mode although i took the picture in landscape.
