Hi,

There's a problem in Rpi4 docker package,
in order to fix it i replaced the following files from cgroupfs-mount debian package
cgroupfs-mount
cgroupfs-umount

The following files are missing as well
containerd-shim-runc-v1
containerd-shim-runc-v2

I got them from containerd debian package

Best Regards.

Du you use the default MLD kernel config? And Du you build the kernel package with the MLD build system (make file)?
Do you update also all depended packages (do a "make all_depends" in the kernel folder)?
Do you also install all kernel depended packages?

[clausmuus]

The kernel has no dependencies.
And if you build and install all kernel depended packages by apt, it should work. If you use dpkg therefor, some pre- and post-install hooks are missing. But they are necessary to change the kernel and initramfs
You can add the "develserver" package to you build environment, to setup a lite package server. Have a look on the MLD Wiki for more infos therefore.

[clausmuus]

The "root" is the user, who build the package. This is actual only an information to see where the package from.
It's normally not a good ide to run the build as root user. But I'm not sure if it's the default in the MLD dev container.
Your problem should not be the "root", but the "Permission denied". There are wrong permissions on some files ()maybe in the folder /lib/modules/...
If you remove the root from the package version. your new packages would no longer prefered on installation. In this case until installation some old packages will be used and not all new.

[clausmuus]

I don't know if the kernel package is OK, but it is installed.

You must set a
DEVELOPER = ""
in your Makefile.config

But then you can not use the develserver any more. So it's not recemented.

You must set a
DEVELOPER = ""
in your Makefile.config

Now conrol file looks as follows:

Code: [Select]

Package: kernel
Version: 5.12.6.203-204+""
Section: system
Priority: required
Essential: yes
Maintainer: Claus Muus <mld@clausmuus.de>
Architecture: armhf-rpi4
Multi-Arch: foreign
Homepage: http://www.minidvblinux.de
Installed-Size: 5224
Description: The Linux Kernel
I used DEVELOPER = instead.

Now i have to delete package folder from all packages 

I'd better wait till you fix the patches to be working with kernel 5.12.6 then will start from scratch.

Are you going to fix it soon?

Best Regards.

If i set DEVELOPER = in Makefile.config it will remove +root from the package name only.
However if i downloaded any package from the develserver +root will be in the control file.

Best Regards.

[clausmuus]

Then the packages would not be rebuilded. The option is for both, the filename and the control file.

[clausmuus]

We use the kernel config file, that is part of the kernel package.

[clausmuus]

You must specify the audio device (plug:iec958) you want to use, like we do for the sofhddrm. It is not configured in the asound.conf, since it needs a other syntax than the devices for all other platforms.
If I remember right, the vc4-kms-v3d-pi4 is an old syntax, that are not supportet any more.

[gr4vity]

Hi Claus,

I think the audio problem i have is different than sofhddrm.



On a working MLD kernel 5.12.6

There is vc4-hdmi-0, vc4-hdmi-1 sound cards.



On MLD kernel 5.12.6.203 i build in dev container

There is no sound cards.

I can't see vc4 module in lsmod.

It seems that vc4 module isn't configured properly , even if i run modprobe vc4
There is no sound cards.

Should i build the kernel again with vc4 built-in?

Bdw: i'm using pulseaudio.

Best Regards.

Hi,

can you teste with

dtoverlay=vc4-kms-v3d,noaudio

in the config.txt

best regrads,
  Roland

[gr4vity]

Hi Roland,

I tested that, unfortunately it didn't work.



I think the problem is due a missing module, i have checked a working alsa package and the package i build.
There is a missing seq folder and snd-seq-device.ko
Could that be the reason?
How to enable it in the config file?

Best Regards.

[gr4vity]

Hi,

I have checked a working MLD system, kernel v5.12.6

If i used dtoverlay=vc4-kms-v3d in config.txt then i'll have no sound cards.

So, it's not related to snd-seq-device module.

You guys can try that too.

Best Regards.
