   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.
