There are a lot of things missing for qemu-system-alpha to be available: - the PALCode emulation is far from being complete or even usable - there is no hardware machine emulation for Alpha in Qemu. As I have no Alpha platform, I don't know much about the hardware to be emulated. But the first step about the Alpha target would be to properly debug the linux-user-mode emulation, that would validate the core CPU INSNS emulation part. I guess my Alpha CPU and ABI knowledge is too restricted to find the problem of most program crashing for now. It seems to me that the Unique register is not initialized properly, but this is just a guess and I have no idea of what's going wrong with this register and what should be its value. -- J.
