I note that this driver also applies to all AMD Ryzen AI 5 and AMD Ryzen
AI 7 processors such as those installed into Framework 13 AMD
and Tuxedo Infinity Book 14 laptops.
The userland software for this driver is completely missing in Debian.
Cordell Bloor has done an initial writeup of what is needed at
https://wiki.debian.org/XDNA
In any case, the availability of this driver would lay the foundation of
forwarding the hardware device into podman containers that would
actually be able to make use o the functionality. Therefore, I suggest
that the addition of the driver would be useful to enable tinkering with
this hardware feature.
