Debian formed a ROCm Team a while ago and we are working hard on getting this to work out of the box, as in: apt-get install and you're done.
For various reasons, our initial focus was on RDNA2 and CDNA2 and earlier, mainly because we are building a CI network in which we test all of our packages (and their reverse dependencies) on actual cards, and we had to bootstrap the network infrastructure first. CI is central to the Debian ecosystem but all our official infrastructure cannot deal with the requirements for specific hardware attached to a machine -- that was never a factor, until now.
AMD has generously supported us with hardware donations, among which are RDNA3 cards. These are already in our possession, and it's just a question of person-time until these are integrated into our CI. We are already spec'ing the systems, though.
