Hi Gregg, AFAIK the leon3-generic can emulate the GR712RC with some little differences in the memorymap and / or timer / CPU count. (You should be able to boot the Gaisler monocore linux with it).
About the SMP support AdaCore had a few patches for it, I'll let Fabien answer.

Does QEMU support these two multicore configurations at present? Is there an effort planned to provide multicore LEONx emulation? I've cc'd the people listed in MAINTAINERS for Leon, but as far as I cansee there have been no Leon-related commits for a few years, so I don'tthink this area of QEMU is being actively developed. We seem to havecurrently LEON2 and LEON3 CPU support, and one machine type, the"Leon-3 generic" machine. thanks -- PMM
