Re: [OpenBIOS] SS-10 and SS-20

I'm curious whether support exists for sparcstation's 10 & 20 yet.
Any comments?

OpenBIOS can be used as the BIOS for QEMU and for this combination,
SS-10 and SS-20 work pretty well.

If instead you'd like to use OpenBIOS as a replacement for the OBP,
then this is not supported. It would be possible to replace QEMU
specific parts (for example fw_cfg) with bare metal versions, but so
far nobody has been interested enough to start hacking. Being able to
run on real HW would certainly improve the level of realism, for
example SBus probing is not implemented.

Am I missing something, or do the QEMU SS-10 and SS-20 not have the 
CS4231 wired up as a serial console?

I don't think real SS-10/20 used CS4231 (Crystal semi audio) either,
that was only on SS-5. Maybe you are thinking of the AMD
serial/audio/ISDN chip, DBRI? That one is not implemented. The console
uses Zilog serial.

need help building sparc32 crosstool

[Robert Reif]

It's been a few years since I did any qemu and openbios hacking
and I want to give it another try.  I'm using ubuntu 10.10 on a PC
but my last development work was on redhat 9 so things have changed.

I need to start from scratch so could I get some advice on what
compiler and glibc version everyone is using.  I remember getting
a working crosstool took some effort but I don't remember what I did.

I assume people are still using crosstool-0.43? It that still true?
What about crosstool-ng?  Something else?

Thanks in advance,

Bob.

I didn't use anything special. OpenBIOS does not need glibc or kernel
headers, so that makes things a bit simpler.

Great news! Are you interested at looking at some of the outstanding 
Solaris issues at all?

I ended up just building my own from scratch following various guides on 
the internet, starting with binutils etc. Currently I use GCC 4.5 for my 
SPARC32/SPARC64/PPC32 testing.

HTH,

Mark.

I am interested in getting more of SuperSPARC working.  The problem is
most of the interesting stuff in the CPU is accessed using memory addresses
rather than ASIs by OBP and even bds knows about some of the addresses.
I had exposed both MBus and XBus functionality so Sun4D development is
possible.

I believe I posted my SuperSPARC work a few years ago for someone to pick
up but no one did so I'm considering picking it up myself again.

I have a lot of real hardware.  I have at least one of every Sun4M machine
(I only have 1 java station) so I can compare QEMU/OpenBios to real
hardware.
