[KERNEL][E5823] GreenKernel for Nougat (stock ROM)

[kryosan]

@GreyLeshy, could you please update e2fsprogs to fresh version, if this possible? AFAIK, there's should be added support of mounting ext4 via fuse.
UPD: yes, it's there!

Homepage: http://e2fsprogs.sourceforge.net/
Git: http://git.kernel.org/?p=fs/ext2/e2fsprogs.git;a=summary
Changelog: http://e2fsprogs.sourceforge.net/e2fsprogs-release.html#1.44.5

And fuse2fs is the module that I really want (it's part of e2fsprogs source):
https://blueprints.launchpad.net/ubuntu/cosmic/arm64/fuse2fs/1.44.1-2
man fuse2fs : http://man7.org/linux/man-pages/man1/fuse2fs.1.html
man mount.fuse: http://man7.org/linux/man-pages/man8/mount.fuse3.8.html

If I have free time will make.

Hi,

first of all, thank you GreyLeshy especially for your hard work (I can really imagine the time it took as I'm now trying similar work) and all the contributors and testers of your kernel. I'm now cherry-picking from your repo and trying to create alternative kernel for suzuran on LOS 14.1 inspired by your kernel. First I've synchronized suzuran LOS sources with upstream, f2fs for 3.10 and CAF. Then around november last year, I began synchronization with your sources. Unfortunatelly, my kernel is still plagued with one problem, which I'm unable to solve.


This always happen only on idle phone with screen off, with frequency of every 4 days in average:

I think it happens during suspend after the log "Disabling non-boot CPUs", I have to say that it was a surprise to me, that android kernel is using some sort of frequent suspend-to-ram procedure to save power, but I consider it now to be some hardware specific feature of arm soc, which is far from common OS suspend to ram (I wasn't able to find more documentation about this functionality). Anyway, from the log, I suspect that the bug is most probably in his part of power suspend or wakeup code (as a side note I still dont understand the purpose of powersuspend patch and its adreno-idler dependency - however disabled, I know), my second suspect would be power efficient workqueues or something around tickless/nohz, or some unfortunate combination. I was only able to identify the root cause somewhere between initial 300 commits I've cherry-picked at the beginning from green kernel, but because this problem manifests once every 4 days in average, I started paying attention only when I was at least 3k commits forward, when at some revision suddenly the bug was triggered in several hours. I was then able to go back a little to the point where the probability of this is still those 4 days in average, and then tried to revert some patches which I suspected can cause this. To make the story short - I had't succeeded, I always reverted 4-5 patches, after approximtely 4 days phone rebooted, then I repeated the same procedure for a whole month (last what I reverted was state nofifier, but phone reboots after day 4 on different crash caused by some android userspace - can't remember the name but is part of android sources - responsible for power management). I have given up, reverted the changes and continue different way. I post this here only just for the case someome would be able to provide any usefull info or advice on the matter, but I really don't expect that. I also post this as more detailed explanation for others from suzuran LOS thread here on xda, and I'm gonna post other update about the kernel development now to Berni's thread, so you can check it there if you're interested.

how can i remove this core clean?

Hello! Thanks for upload.

I'm not an "advanced" user. Would you recommend getting this update anyway?

Regards,

EDIT: Oh and again, just wanted to mention that I can't put more power to specifically big cores, just global, on all cores. It's on +5mV now, thinking of trying +10. What is usually the numbers here? How far am I safe to go, just to prevent the phone shutdowns? It's becoming annoying by now, I can't trust my phone at all during calls.

For normal use, a stock kernel is sufficient.

Stable voltage for kernel.

This is how my voltages look atm

after some time i got back to stock kernel with grey 1st kernel so far super stable (i just need root and no other customizations)
btw i found out some "custom rom" stoled your kernel (and they also stole the roms from other people)
edit :im using RC12 Pre-release at the end the best stable so far (stock patched wifi didnt wor)

Wich rom?

hey my video recorder in front camera dosnt work(get stuck)
anymore tried front camera recording with lastest kernel Kernel 25.02.2019 RC12 g5a9eacf.?
because this is the only problem beside that no problems

ps: even at 3rd party app front video recording get stuck

im not sure if this is kernel related

but even if it is, i prefer this on other roms\kernels combo

 

[kryosan]

@GreyLeshy lastest kernel 25.02.2019 RC12 g5a9eacf looks very good, but seems to lack KCAL driver. Was it removed on purpose?
@Superrman I can't find any issues with front or rear cameras.

 

[kryosan]

Default interactive governor is way too power-wasting. Now I'm trying electron governor, it looks much better in power terms.

Actual quantity of nesting levels is more than 4000. Even if bottom directory has only a few kilobyte file, directory structure itself could use more than 200 megabytes!

The only way I could delete such paths without formatting whole card is the Windows program called "Dlinnoput 2".

In terms of battery, version 1.10.28 IS the best for me, but video recording produces corrupted files.

Actual quantity of nesting levels is more than 4000. Even if bottom directory has only a few kilobyte file, directory structure itself could use more than 200 megabytes!

The only way I could delete such paths without formatting whole card is the Windows program called "Dlinnoput 2".

After using Dlinnoput 2, exFAT table became corrupt, so android mounted exFAT in r/o. Any tool couldn't fix that. I've tried:

1. windows chkdsk with keys /F /X /R — exits with reading structure error; /F /X — couldn't find any errors;
2. linux fsck.exfat — each time produces random errors;
3. android's exfatck -r -s /dev/block/mmcblk1p1 — fixed some FAT structure errors, but re-running previous two tools after this one, produced same results: r/o.

So, that was way too much struggle with this exFAT piece of $h1t. It hasn't any pros over FAT32. It's buggy. It couldn't be repaired if broken. Opensource exFAT driver, written by single guy can't be more stable, than good old FAT32 driver (stable, universal, could be fixed under almost any OS). I have reformatted my 64GB SD card's exFAT to FAT32 with this tool: https://xdaforums.com/tmobile-lg-g3/general/guiformat-fat32-simple-windows-sd-card-t2960190

If anyone bothered about wear leveling: all current SD cards have their own controller with FTL. We don't really need exFAT or f2fs on modern SD cards.

PS: I don't care about files larger than 4 GB.

Hello everyone, I do not quite understand, after removing the factory lock, root and flashing another kernel to the stock firmware, what will I lose? Screen enhancements, noise reduction, sound enhancements, etc. will stay?

 

[trax7]

@GreyLeshy if you are still sometimes looking at this thread, good sir, here are some logs from a random reboot mid-call

Thank you for making the best kernel for our Z5C! :highfive:

 

[trax7]

Sorry for double posting, forgot the logs xd

Sorry for double posting, forgot the logs xd

It seems so random who is affected by this and not. I didn't have any issues to begin with, now it's pretty much every call unless I pump up the voltage to the point where my battery can't hold up. Massive heat increase. If I really need to use my phone I go through maybe 5+ reboots a day, and I just cba doing something about it so just went with it hoping the reason would unveil.

Waiting patiently.

Yeah, although I think the problem is somewhere else. You might have an undervoltage-induced error only because of one of the frequencies. So not all the voltage settings, just a particular one.
And only that one is giving you trouble. It was like that with my Z5C. Ofc, if you get more reboots then either your voltage for the problematic freq is too low or you have several problematic frequencies.

Apart from that, my Z5C is pretty stable. So if there is an error, it's from a race condition somewhere that's exacerbated from the inaccurate voltage tweaks.
