Public bug reported:
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.
