I've been focused on making cross-compilers and using those to create kernels and a minimal native build environment I could use to natively compile packages with. (The way I designed the thing you could substitute real hardware for the qemu step, assuming you had it. Or another emulator like armulator for a specific platform.) I don't believe QEMU emulates parisc yet, although it adds new platforms all the time. (It just grew an alpha emulation last month.) It's under very active development. Rob
