Valve Steam Deck and T2/Linux
A Linux native, x86_64 AMD Zen 2 based portable gaming console. The Steam Deck includes a custom 0405 APU built by AMD, named Aerith, with 4 cores, 8 threads and the GPU runs on 8 RDNA 2 compute units.
The Steam Deck boots using a regular UEFI BIOS and therefore can boot modern T2 easily, e.g. by holding the Vol- button while turning the unit on.
