AMD BC-250 is a mining board based on an AMD APU with an integrated GPU that kernel recognizes as Cyan Skillfish. It is basically RDNA1/GFX10, but with added hardware ray tracing support. LLVM calls it GFX1013, see https://llvm.org/docs/AMDGPU/AMDGPUAsmGFX1013.html Support for this GPU hasn't been extensively tested. Some games are known to work, some non-trivial ray query compute and ray tracing pipeline rendering works too. Q2RTX works. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/33116>
