Turns out that the mobile processor in this server is so new that #AMD hasn't released #ROCM libraries for the integrated GPU, a #Radeon 780M - GFX1103, yet. "New" is relative; AMD is, seemingly, terrible at releasing code to keep pace with hardware releases. To contextualize how terrible, ROCM just got support for the 7900XT in the last 3 months; this GPU was released in December of 2022. I wish external GPU enclosures weren't a million dollars.
