[KERNEL][Android 10-13][OOS/Custom] mcd-kernel [r19]

[mcdachpappe]

Hello,

this releaase add's another kernel type ' _custom-los-fod' because of the latest LineageOS FOD driver code changes. Choose this build on custom ROMs if you are having FOD issues.

Thanks - again - to anyone who improves this project with me. Enjoy!

# Changelog:​

• Compiled with mcd clang v13 for maximum stability
• Upstream AnyKernel3 source
• Upstream up to android stable-linux to 4.9.272
• Downstream wifi drivers to CAF tag 'LA.UM.8.3.r1-06900-sdm845.0'
• Fixup vbswap initialization
• Disable userspace / CAF cpu boosting [fixes max cpu frequencies while scrolling / flinging]; bd81a3c
• Add devfreq_boost driver and introduce a kind of frame boosting; bd433c1
• Replace lmkd with simple_lmk

# Notes:​

Choose the correct kernel .zip file depending on your current ROM:

• _oos: OxygenOS 10.*
• _custom: Any AOSP based custom ROM
• _custom-los: AOSP based custom ROM with LineageOS displaymode handling (livedisplay)
• _custom-los-fod: Custom ROM with LineageOS displaymode handling (livedisplay) + updated FOD code

# Download:​

Github: mcd-r5​

FKM Updater configs: oos | custom | custom-los | custom-los_fod

# Installation:​

Dirty flash over any previous mcd-kernel is just fine. Consider a clean ROM flash if you are coming from any other custom kernel!

thanks for reporting. I assume you are using an _oos variant? please re-download it, it's fixed now

Using crdroid for past 3 months.
one issue
my wifi stuck at wifing turning on and doesnt turns on. it works only with mcd kernel that too r3 april build only. latest mcd kernel r4 too doesnt switch on the wifi.
crdroid ROMs last mcd build and may months last release candidate wifi worked out of the box but the latest build also wifi doesnt turn on but as i flash mcd rc3 it works..

Tried a fresh install of the rom
tried with oos latest zip flashing to both slots
then flashed the crdroid still no luck of wifi working with stock kernel as soon as i flash mcd r3 it works

Which one did u flash? People who flashed custom-los-fod had the alert slider toast showing mute for all modes. Not sure if custom-los would go fine

Thanks for the update, just want to make a report and see if anyone else experienced it on their end. After upgrading to mcd-r5, after the phone goes to sleep the WiFi somehow was automatically disconnected. It will reconnect again after turning the screen on.

I'm currently on OOS 10.3.11, and all the options in the Settings -> Wi-Fi & internet -> Wi-Fi -> Wi-Fi preferences is turned off.

That's caused by a battery saving feature of OOS, I'm not sure what the name of the feature was since I'm running a custom ROM for quite some time. But I am pretty sure the feature I'm talking about it located somewhere in the battery menu in the settings.

that's what I first thought too, but I've always turned off battery saver option in the battery settings. I didn't change any settings in the OOS before flashing mcd-r5, was previously on mcd-r4 and didn't have this behavior.
anyways, I'm just posting this to see if anyone else had the same experience or it's just me. If it's just me, then it's probably something wrong on my end.

No, I'm not talking about the standard battery saving options but those with literally "WiFi" in the name, there's an OOS feature that automatically turns WiFi off as soon your phone goes to sleep. It's tucked away in some menus. Sadly I can't remember where it's exactly located. But to me it sounds like that feature is enabled on your end.

Have a look at:

Settings - Battery - Battery optimisation - Advanced optimisation (3 dots at the top right corner) - disable: 'Sleep standby optimisation'

This is what @Mr.FREE_Bird is referring to

I was remembering from other ROM that had the setting called "Turn off WiFi on screen off" or something like that but couldn't find that in OOS. I guess "Sleep standby optimization" is what they called it in OOS.

I have checked that and it's already disabled:

I'm currently reverting back to mcd-r4 and the WiFi is behaving normal. It's alright, R4 is doing fantastic job anyways, so no worries. Thanks for trying to help.

Have you flashed the latest oxygenos to both slots? There are rumors that this might fix some signal / wifi issues if it's installed to both slots.

Yes, I always flash the ROM on both slots, never had signal or wifi issues. Just found it weird that I'm only experiencing wifi disconnection during screen off on R5 but not on previous releases. Maybe it got something to do with the wifi drivers being used in R5 that didn't play nicely with my router.

Wifi still broken for me on r4 (didn't try r5 b/c it doesn't list any wifi changes in changelog). Initially things work fine, but eventually I will find that my wifi is on but not connected to the local wifi and the list of available wifi networks will be blank. The only way to fix this is to reboot the phone. There have been improvements with each "r" version, because it now takes longer for this problem to occur in r4, and on some earlier r versions I couldn't connect to 802.1x (enterprise) networks at all.

The last version where wifi works 100% properly is 11/14/2020. I'm on the latest stock Oxygen OS, latest stable Magisk.

If there are any logs or other data I can provide to help troubleshoot this, please let me know.

thanks for your feedback. please join our telegram group to grab the latest test build which is based on my old kernel tree (this includes your mentioned wifi drivers of 11/14/2020).

Hello. I checked your TG group and found the test kernel just for OOS. On R5 I am having yet again the same 2.4GHz WiFi performance issue (using RRemix). I'll keep an eye out for a Custom variant of the test kernel.

 

[Aashay]

I am on the latest version of the kernel and using FKM app. I wanted to block wakelocks but I am unable to see that option anywhere. Any help is appreciated.

That option isn't present via the fkn app. This is a great kernel out of the box as is. I run this kernel and, Nolimits and, this phone is great. Try nolimits 12.0 if you are using Oxygen OS. You won't regret.
