Version of GCC and other GNU tools required to build OpenBIOS Spa rc32
by Armistead, Jason
What version of GCC do I need to build OpenBIOS Sparc32 ?
What about the other GNU tools - what is the minimum set needed ?
I would like to either cross-compile on Windows 2000 (under MINGW or
CYGWIN), or to build on Solaris (choice of systems from Solaris 2.5.1 to
Solaris 2.10 available).
Thanks

Re: [OpenBIOS] Old SunOS boot CDs / ISO images ( was: Starting QE MU with OpenBIOS for Sparc32)

I have a Solaris 1.1.2 (SunOS 4.1.4) boxed kit sitting in my office, plus
some Sparcstation IPX and ELC hardware running Sunos 4.1.3 / 4.1.4.
Possibly I have Solaris 1.1.1 (SunOS 4.1.3) media somewhere too (it would be
in a pile of inherited stuff I got when I got the Sparcstations - sigh !)
So, if you want some files, extracted from these systems or CDs let me know
EXACTLY what you want - go easy on me, I'm still a newbie !
As soon as I can figure out how to make QEMU work best for me (presently
under Windows) I will let you know. I've managed to get it to build under
MINGW, after working around the dependence on fsync() function calls in some
of the disk image handling modules (which does not exist on Win32). Which
reminds me, I need to feed this back to the QEMU developers !
Alternatively, I can try building QEMU under Solaris 10, 8, 7, 6 or 5, all
of which are running on one or more of the workstations in the office - I
probably need to sort out the right GCC and GNU tools to use for these
though, so any help appreciated.
My long term goal is to be able to switch off the Sparcstations entirely so
that we can retire the ageing hardware, and fire up a "virtual Sparc"
whenever I need to do some legacy work. I've had similar success with DEC
hardware guru Bob Supnik's SIMH, a VAX emulator, which runs the entire VMS
operating system on it (see http://simh.trailing-edge.com) or can also
emulate a number of other interesting nostalgic CPUs and systems. I reckon
if they can make VMS run reliably in an emulator, that's VERY impressive.
Hopefully one day QEMU / OpenBIOS can be so good.
The only downside with QEMU and SIMH seems to be that they eat 100% of my
CPU because the target CPUs do not use any sort of HLT mechanism to pause
the CPU when idle - at least on a hyper threading CPU it is only running at
50% according to task manager !

Re: [OpenBIOS] Starting QEMU with OpenBIOS for Sparc32

Do you keep this proll.elf (which is really OpenBIOS) up to date with the
latest SVN snapshot ?
If not, maybe you could generate a proll-svn.elf file which contains the
latest from SVN for people without access to the cross tools (and leave the
proll.elf as the latest "stable" version)

On Windows, starting QEMU with -nographic is not possible because it keeps
on saying
qemu: could not open monitor device 'stdio'
I'm guessing it works OK on Linux and Unix QEMU, but what to do on Windows
where the concept of "stdio" is not as well defined ? Is there a workaroumd
/ hack for QEMU or something I need to configure on Windows ?

Crude Patch
by Jason Hooper
Hi all,
A very very crude patch to get the Solaris boot to go a bit further. We are missing the definition and code for vector v2_dumb_mem_alloc. I have tested with various addresses for the dumb memory alloc, but I am sure there are others on the list who know enough to do this properly!
I now get errors about device sizes after the Solaris kernel boots. I even get the rotating cursor for a little while!
