Greetings!
Are you all still looking for arm64 testers? I've been running a Radeon RX 7900 XT on my RPi 5 for a few months now, and recently started looking into whether or not AMDVLK or ROCm supports arm64, yet. I happened upon a post in LevelOneTechs, and then found the APT archive page for this group. FWIW, I have multiple 16gb and 8gb RPi 5's to test with, and they are mostly running patched versions of the 6.12 kernel, but I've been using 6.14, lately. I'm not the original author of the patches, but I have ported them over (from 6.6) to work w/ 6.12 and 6.14, and maintain them here,
https://github.com/nicholasaiello/linux/pulls . Patches aside, it'd be pretty compelling to demonstrate that your build of ROCm works w/ arm64 platforms, like a Raspberry Pi.
