Yes this can be closed, no problems now using open bios to boot Solaris
and it does support multiple processors though this is actually slower
than one.

Title:
qemu-system-sparc w/ SS-20 ROM does not add processors

Status in QEMU:
Fix Released

Bug description:
When booting a SPARCstation-20 with the original ROM, qemu does not
set the number of processors in a way that this ROM can understand it,
and the ROM always reports only 1 processor installed:


~/qemu  /usr/local/bin/qemu-system-sparc -bios ./ss20_v2.25_rom -M SS-20 -cpu 
"TI SuperSparc 60" -smp 2 -nographic

Power-ON Reset


SMCC SPARCstation 10/20 UP/MP POST version VRV3.45 (09/11/95)


CPU_#0 TI, TMS390Z50(3.x) 0Mb External cache

CPU_#1 ******* NOT installed *******
CPU_#2 ******* NOT installed *******
CPU_#3 ******* NOT installed *******

<<< CPU_00000000 on MBus Slot_00000000 >>> IS RUNNING (MID =
00000008)


...

Cpu #0 TI,TMS390Z50
Cpu #1 Nothing there
Cpu #2 Nothing there
Cpu #3 Nothing there

...

SPARCstation 20 (1 X 390Z50), No Keyboard
ROM Rev. 2.25, 128 MB memory installed, Serial #1193046.
Ethernet address 52:54:0:12:34:56, Host ID: 72123456.


(It is necessary use SS-20 since it is the only sun4m model that
supports 512MB RAM, and I can't get Solaris to install on the SS-20
using OpenBIOS.)

When booting with OpenBIOS I can't seem to boot any version of Solaris
though I had heard this did work. Solaris 8 and 9 do work nicely with
this ROM, but I am opening this to see if it is possible to fix this
to allow the original OBP ROM to see multiple processors.
