We do not use the vtuner patch, since it is not funktional. But we build the vtuner as a separate package (dvb-vtuner) by external module build.

Hi Claus,

The kernel panic problem is solved, i can't believe i was using a wrong config file  :o
Please delete that config from dev container.
I took config file from 092021 and it worked.
I will delete all the unnecessary comments i made related to that issue
 
Yes. we discussed qemu ARM emulation in docker before. i hope MLD kernel cross-compile will also work in the future.

Best Regards.

Hi Claus,

BCM2835 thermal driver is enabled in 092021 config instead of BCM2711
Therefore CPU temp for RPI4 is always 00

Best Regards.

Hi,

Code: [Select]
MLD> vkcube
vulkan: No DRI3 support detected - required for presentation
Note: you can probably enable DRI3 in your Xorg config
Could not find both graphics and present queues

Maybe solving the above error can help?

I have looked for a solution but there is only config for Nvidia and Intel,something like that

Code: [Select]
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "DRI"    "3"
EndSection

Code: [Select]
Section "Device"
   Identifier  "nvidia Graphics"
   Driver      "nvidia"
   Option      "DRI"    "3"
EndSection

I haven't found any config for RPI4

I created a config file in /etc/X11/xorg.conf.d/20-broadcom.conf but it doesn't do anything.

Code: [Select]
Section "Device"
   Identifier  "Broadcom"
   Driver      "V3D"
   Option      "DRI"    "3"
EndSection

Any idea?

On MLD you can create a file with the name 30_broadcomDevice.add and this content:
Code: [Select]
   Driver      "V3D"
   Option      "DRI"    "3"
That will merge into the right config file on xorg startup.

Hi,
after creating that file xorg failed to start.
I found that in log
Code: [Select]
[    60.992] (II) LoadModule: "v3d"
[    60.993] (WW) Warning, couldn't open module v3d
[    60.993] (EE) Failed to load module "v3d" (module does not exist, 0)
[    60.993] (EE) No drivers available.
Although v3d module is already loaded.
What's wrong?

I think the problem is not the kernel module but the xorg module at /usr/lib/xorg/modules/...

There is v3d driver also in /usr/lib/arm-linux-gnueabihf/dri/v3d_dri.so

Anyway, according to the following page

https://monkstone.github.io/jruby_art/update/2020/03/21/V3D_Drivers_RaspberryPI.html

Code: [Select]
OpenGL renderer string: llvmpipeis a Legacy renderer

Code: [Select]
OpenGL renderer string: V3D 4.2is FakeKMS renderer
Since there is no raspi-config in MLD i tried to edit config.txt manually

I tried dtoverlay=vc4-fkms-v3d but my RPI4 still using the Legacy renderer.

Hi,

you could compare the config.txt of RaspiOS and MLD.
