Official RPI Kernel on Ubuntu

[isteiger]

Does anyone know how to get the official RPI kernel on Ubuntu ARM 64bit working?

What you are asking doesn't make sense. You want to run the official Raspberry Pi ARM kernel on x86 Ubuntu? Or something else?

I want the official RPI kernel on arm64 Ubuntu, as there is no hardware acceleration on the official Ubuntu kernel. I’ve tried but it didn’t boot afterwards, I think it was missing some kernel modules but I’m not sure how to add modules.

/lib/modules contains the modules - you need to ones that were compiled with the kernel so need to copy them across. May still not work however, and you may not get the acceleration you desire depending on what other libraries (we.g. Mesa) are present.

That may not be possible. What specific hardware acceleration do you need?

I need GPU acceleration.

I need GPU acceleration.

GPU acceleration (open GL, graphics drivers, etc)
and/or
CODEC acceleration (MPEG, H.264, H.265, etc)

They are distinct from each other on the RPi.

I also need GPU acceleration for OpenGL.

Please take a look at the comment I just added to:

Here's the procedure that worked for me for building and running what I thought was the "official" kernel:

Unfortunately, I'm having trouble just now, as noted here:
viewtopic.php?p=1691801#p1691801

But I may have a saved snapshot of my system as of version 1009. If so, I'll to try the proposed config changes and report the results as a comment in the launchpad bug.

Switch your SDCard to one with RaspiOS and run away happy. What's the reason for wanting Ubuntu? Can you wait until the Ubuntu stuff catches up with the RaspiOS stuff?

If you could get by with 3D acceleration in some other 64-bit Linux with recent libraries, then could you also consider other 64-bit distros?

• Gentoo on RPi: https://github.com/sakaki-/gentoo-on-rpi-64bit
• Manjaro on ARM: https://forum.manjaro.org/t/manjaro-arm ... sed/148221

As far as I know, there is no publically available video acceleration in any of the 64-bit distros yet (Raspberry Pi OS 64-bit beta included). Happy to be informed that I'm wrong

I've just gotten GPU rendering working on a pi 4 in 32-bit Ubuntu 20.04.
It just required config changes.

Details here:

I don't know if the same fix works in 64-bit systems.

After upgrading to the latest proposed kernel (5.4.0-1014.14) I have GPU acceleration working! Just add

to

Code: Select all

/boot/firmware/usercfg.txt

after upgrading to the proposed kernel.
