Thanks for all your testing ..

The kernel you like uses static kernel driver .. all new ROM will use kernel module.

For this reason you are stuck at 04. April release .. otherwise no WLAN anymore.

Pls test kernel below .. same 23/03 kernel but using the same wifi driver as kernel module .. to be ready for future ROM updates ..

pie-m105-kernel-3.18.91-gtaxllte-WLAN-20190430.zip

Sources:

https://github.com/followmsi/android_kernel_samsung_exynos7870/tree/pie-m105-hmp-oc-module

Fix for Wifi MAC, Disabled KNOX and CRC for MMC .. otherwise no changes to 23/03 kernel .. no upstream !

Pls compare with new upstream .139 kernel from today .. what are your testing results ?

All kernel installer packages do include WLAN modules now .. to fit current kernel.

3.18.14 kernel in same gdrive kernel folder is using stock WLAN module and should run on older ROM too.

This 3.18.14 kernel is CPU/GPU overclocked - but no HMP - as we break stock WiFi this way !

Cheers

Thank you, i will test the 3.18.91 Kernel :good:

BTW, it's true, i had no WLAN with newer Roms than 04. April :D

Today i deleted my NFS Injector Module, because i switched to FDE.AI from XDA Page.

NFS is very good, but i prefer FDE since newest Release. It's Magic.

Edit:

I tested the 3.18.91 Kernel with 04/04 Rom = No WLAN.

Tested 3.18.91 and the 3.18.139 with 11/04 Rom.

But the Gaming Performance is not good in Asphalt 9 & Darkness Rises.

It lags at heavy special Lightning or Weather Effects / Explosions etc...

Installed 23/03 Kernel with 04/04 Rom again = All smooth, no Lags or Stuttering.

Confused.... Sorry, that i can't report positive Results.

ResurrectionRemix-P-v7.0.1][64-Bit] -> 20190411

Possible a bug. My SD-CARD is use as internal

I had made a backup in the TWRP (3.3.0.2) on the SD-Card. TWRP meant the path is /external_sd/media/0/twrp. But the path on Android is /storage/emulated/0/twrp

and it's empty. Restart in the recovery and under TWRP the backup is available.

I try to search the backup files with the X-PLORE commander, nothing found. The path /external_sd isn't available. Backup on the USB-Stick works
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] followmsi:
Sounds like it's related to module loading/unloading .. we block module unloading in latest releases, due to wifi issue.

Difference to 23/03 kernel.

Will make test kernel for you .. allowing module unload again.

But all kernel will need 11/04 ROM for wifi .. soon the May updates are coming based on updated RR 7.0.2.

Actually I am not sure if this is the root cause .. kernel modules are not magisk modules.

Anyway .. let's test with kernel module unloading.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] followmsi:
The mountpoint in TWRP is different .. yes.

You basically can take and restore backups but you don't see the backup files in Android ?

Not sure .. if encryption is blocking the "view" of the files.

Android uses "/storage/emulated/0" for internal storage .. not sure about adopted storage now.

Not sure when I will have time to replicate this "issue".

[MENTION=5480152]followmsi[/MENTION] did you forget to upload the checksums for the ROM?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] followmsi:
Sorry .. RR Pie does not produce checksums while build process.

Actually the first ROM which does not make some checksums automatically.

RR may add them in the next time ..
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] soaringowl2145:
Can you please at least tell us the checksum manually?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Diabolus_Musica:
What's the big deal with the checksum? If you download it from where he says and it works then it's correct, no?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] soaringowl2145:
I don't know about you but I would like to make sure it works before I flash it and I don't like doing things twice do you?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Diabolus_Musica:
I see your point but if it downloads the complete file without errors why would it not work? Now I could see if some 3rd party site was hosting the file and you'd want to make sure that they didn't tamper with it, but this download is directly from the source. This is an excellent rom by the way.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] soaringowl2145:
yeah I see your point but I still like to do the checksums anyway regardless. Though as far as tampering is concerned the checksum is not going to tell you whether or not it has been tampered with. The only thing that would tell you if it has been or not is with verifying a signature and determining whether or not the signature matches. It's just simply something I love doing and I've got in the habit of doing.

Ok thanks for the explanation, I was just curious.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] soaringowl2145:
Also in RR Oreo when you update/download and install an app from the play store there would be a notification that it is downloading and installing. In RR Pie the only notification is after the app is installed. This issue also occurs in Lineage 16 by Valera.

Is this a bug or is this normal behavior for Android Pie?

Good news !

Added the LTE version too ..

pie-m105-kernel-3.18.139-gtaxllte-WLAN-20190501.zip

As we know the root cause we can make new "gamer" kernel easily ..

https://github.com/followmsi/androi...mmit/759d351ff7b7f3d68783febd3208dee454a3074e

Pls be aware that this kernel (05/01) will not survive the "Naptime app - deep sleep test".

If you loose WiFi pls reboot device.

For the next RR ROM we will use 04/30 kernel .. without module unload - just for the WiFi module.

You can always flash 05/01 on top of all new ROM .. if there are major changes we will make new "unload" kernel for the gamers :)

ResurrectionRemix-P-v7.0.2 - May 2019

I have added a new version of SamsungDoze .. this way AmbientDisplay works too.

For AmbientDisplay we need to check Nougat/Oreo ROM .. maybe stock ROM too.

Did open/swipe of AmbientDisplay notification ever work on 580/585 devices ?

For this ROM I have used "3.18.139 (04/30)" kernel .. and kernel module unloading is not working.

For the next time there are 3 different kernels available ..

3.18.14 - stable stock WiFi module but "4" cores only. (if you have heavy load the other 4 cores are online too)

3.18.139 (04/30) - latest kernel with "8" cores (HMP) - kernel modules are not unloading - to survive Naptime WiFi deep sleep.

3.18.139 (01/05) - latest kernel with "8" cores (HMP) - kernel module unloading is allowed - gamer kernel !

Here we are ..

RR-P-v7.0.2-20190511-gtaxlwifi-Unofficial.zip

RR-P-v7.0.2-20190511-gtaxllte-Unofficial.zip

Changes:

RR-P-v7.0.2-20190511

- Google security updates -> May 2019

- kernel: Upstream to 3.18.139 (other minor changes)

- Re-enabled Samsung Doze

I'm sure Ambient Display swiping/tapping used to work on my T585 ... I thought it was with RR Pie but maybe it was on RR Oreo :confused: ... but I'm like 98% sure that it worked at some point.

What is "kernel module unloading" and is it bad if that doesn't work?

Thanks for the update :) :good:
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] fiddi1973:
A kernel module is a program which can loaded into or unloaded from the kernel upon demand, without necessarily recompiling it (the kernel) or rebooting the system, and is intended to enhance the functionality of the kernel.

In general software terms, modules are more or less like plugins to a software.

The Kernel with unload function provides better Gaming Performance, because some unused Modules will be unload.

We need to know name and/or date of the ROM where open/swipe was working fine.

I will not have the time to test Nougat and Oreo ROM soon.

It seems we miss required kernel support to make open/swipe possible.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] followmsi:
Due to various reason (size, functionality ..etc.) you can move kernel code from kernel binary into kernel modules.

The kernel binary is located in boot.img and the modules are located in system.img.

The kernel modules can be loaded and unloaded without reboot, if configured.

Kernel modules have to fit kernel binary version.

If you change kernel config too much or use upstream patches you break this compatibilty.

Pls search on Google to get more infos about kernel modules.

For SM-T580/585 we are using Samsung stock WLAN kernel module in system.img to make WiFi working at all !

The stock Samsung WLAN kernel module is used in Nougat, Oreo and Pie.

Actually we just use one single kernel module for 580/585 devices - this "famous" WLAN module.

We are "fighting" with this stock WLAN kernel module since day one.

Starting with kernel "pie-m105" (3.18.91) we got (again) problems to make stock WiFi module running and started to use

fresh own built WLAN driver from sources.

The first driver was built-in into kernel binary (no module) - the following drivers were built as module again.

For this reason some ROM last month were not getting Wifi connection at all - if they used different kernel.

This fresh built WLAN driver from sources is part of the current ROM .. but we do still have problems some problems left.

(deep sleep with naptime app .. reboot to get wifi back .. etc.)

As a workaround for "Naptime app deep sleep" we block module unloading. (04/30 kernel + 05/11 RR ROM)

Magisk modules have nothing to do with kernel modules !

The "gamer" kernel needs "module unloading". (01/05 kernel)

As it looks like "module unloading" is related to "stop_machine" (bring offline single cores)

The gamer module wants to stop kernel cores, apply performance config and bring cores online again.

If the magisk gamer modules can not bring down/up cores you will not use/apply their "performance" config.

Need to check this again later on .. in case we disable modules completely.

Pls check Google for general infos about HMP (heterogeneous multi processing) - explains 8x1 cores and 2x4 cores.

Sorry .. no more time left for better and more detailed explanation.

Enjoy RR :p

Quickly asked in monthly Lineage Nougat thread .. here Ambient Display seems not work at all .. not even show the messages.

Oreo is left for testing/verification .. but no more time.

Are you able to restore Oreo to verify if swipe/open works ? .. 100% and not 98% :)

Maybe it works on Samsung stock Oreo ROM (only) ?

We may ask stock users in their XDA thread.

Like for Wifi driver topic too ..

If Samsung "forget" to publish all kernel sources we will have much more problems to makes things working.

Thanks for the search- but what I should have said is I've done this on previous Pie ROMs... On the latest RR and AICP incarnations I've tried (oh God bless you Devs) I don't get the option to move any app/data to external. Lots of apps won't move, granted, but none I select offer "change storage" anymore.

It's not the end of the world as I know it, just struck me strange. Some medical apps use huge app data files, so I might go to the "use my SD as internal" instead, that would work too.
