I've tried to find the missing drivers for my system (Ubuntu 22.04.2). I've
looked in packages.ubuntu.com as well as cloned the newest Git repository
(git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git).

The missing drivers (e.g. vega10_cap.bin) are nowhere to be found. 

Then I've stumbled across this page, named "Updated Open Graphics Drivers -
since 2011!":

https://launchpad.net/%7Eoibaf/+archive/ubuntu/graphics-drivers

I'm not sure what this is. It doesn't seem to provide what's missing.

In the Askubuntu page you mentioned, there a PPA is desribed, but I couldn't
find the missing drivers there. I'm hesitant to include it nonetheless,
because I don't want to risk breaking my system.

I've googled around, and found a couple of pages with the same or a similar
problem, but couldn't find the vega10_cap.bin file anywhere.

Why do those warning messages refer to some drivers as missing, when they
appear not to exist anywhere...?

Cheers,
Volker
