Yes, math emulation should just work on 32-Bit PowerPC. > In fact I found some discussions from 8 years ago that said tha A1222 can > in fact run powerpc code with the MATH_EMULATION kernel option enabled. > It's not recommended, since the FPU performance is terrible. There is no other option at this point unless one wants to invest time and effort to build Debian for powerpcspe with LLVM/Clang. Also, as already mentioned in the other mail, the driver support for A1222 was never upstreamed. > I will continue to despise the A1222 even existing for the fact they > put that garbage CPU on it that is not a proper powerpc and broke all > existing compatibility of AmigaOS 4 FPU using code. Yeah, that CPU was an unfortunate choice given that Linux support for it was lacking as well. One option is to install FreeBSD which is currently supported on A1222: See: https://www.freebsd.org/platforms/ppc/#hardware Adrian -- .''`.
