Version of GCC and other GNU tools required to build OpenBIOS Spa rc32
by Armistead, Jason 07 Jun '06

07 Jun '06

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 Jason

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) >NOTE: This one only works with -nographic, as the framebuffer handling >code keeps most OS boots hanging. 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 ? Thanks Jason

Crude Patch
by Jason Hooper 07 Jun '06

07 Jun '06

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! Regards,
