Re: Support for Gaisler multicore LEONx SoCs

[Frederic Konrad]

Hi Gregg,

AFAIK the leon3-generic can emulate the GR712RC with some little differences in the memory

map 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.

Regards,

Fred

We are considering the Gaisler GR712RC (2 core LEON3) and GR740 (4 core LEON4) SoCs for a new deep space mission.

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 can

see there have been no Leon-related commits for a few years, so I don't

think this area of QEMU is being actively developed. We seem to have

currently LEON2 and LEON3 CPU support, and one machine type, the

"Leon-3 generic" machine.

thanks
