[Qemu-devel] SMP Proll image

[Blue Swirl]

Hi,

The attached Proll image can be used to test Qemu (latest CVS) Sparc32 SMP 
support. Example:
$ qemu-system-sparc -L  ~/proll  -kernel ~/vmlinuz-2.2.17-14smp  -append 
"console=prom -p" -nographic -smp 4

And then the kernel hangs.

At register level, Sun4m architecture supports up to 16 CPUs, but Linux 
limits the number to 4. I guess that's the hardware limit on real machines.
