[Qemu-devel] Adding SMP support for Sparc Target

[Damien Hilloulin <damien.hilloulin@epfl.ch>]

Hello everyone,

I'm a newcomer in QEMU and my goal would be to port an existing system 
simulator using another emulator to QEMU.
Some work has already been done, and Sparc has been the main target so 
far because of its simplicity (and because we have a very good support 
for Sparc with the other emulator).
QEMU is great, open-source (contrary to the other emulator we have been 
using in the past), and that's why we are aiming at using it.

However, it seems that the Sparc targets doesn't really support SMP/CMT 
as of now. So I am considering two possibilities:
- adding SMP support in QEMU for the Sparc targets (and contribute it to 
QEMU :) )
- switch our focus to another arch wich supports SMP/CMT in QEMU e.g 
x86, ARM (lot of work for us : ( )...

So that's why I'm writing to you, to judge how feasible it is to add the 
SMP/CMT support for the Sparc Targets.
I'm not a Sparc guru at all, so I don't really know what would be the 
steps to add this support.
Do you have any idea about how to approach it? Do you know where I can 
find some good documentation that could help me?
How much time it would take for someone having 3 or 4 hours per day to 
dedicate it?


Thanks for any help,

Best Regards,
Damien.
