Subject: [Qemu-devel] SPARC32 SMP booting problem

We are trying to build a tiny SPARC32 Linux SMP kernel for debugging use.
The kernel is compiled with SMP support and Enhanced RTC.

With the command line parameter
   -M SS-600MP -smp 1
the kernel boots successfully.

But with
   -M SS-600MP -smp 2
booting will hang at

SILO Version 1.4.13
boot:
Loaded kernel version 2.6.18
Loading initial ramdisk (3212127 bytes at 0x3000000 phys, 0x60000000
virt)...
PROMLIB: obio_ranges 1
Booting Linux...

In addition, Debian netinst cdrom will hang at this point if booting with
SMP.
NetBSD with an GENERIC.MP kernel can only recognize one core when booting
with 2 cores.

Is there some bug with the SPARC32 SMP implementation?
Or any one know how should I configure the SPARC32 Linux kernel to
boot correctly with SMP?


Many thanks!
Naruil
