The PS5's custom I/O complex (that hardware decompression unit) must have been a headache to work around — did you end up bypassing it entirely or did you manage to get any of that throughput exposed to Linux?
I'm curious about thermal behavior under sustained load. The PS5's cooling is tuned tightly to the stock firmware's power envelope; running arbitrary Linux workloads probably hits different thermal profiles. Did you see throttling during long gaming sessions, or is the headroom sufficient when you're not pushing the RSX equivalent?
Linux and GPU drivers had already been ported to the BC-250, which was a binned down variant of the PS5 processor.
The driver change to support the actual PS5 was a 1-line fix to make it recognize the slightly different GPU ID on the PS5
