Apparently there are some limitations on the C/H/S parameters you use for the disk that correspond with how UFS wants to format a new filesystem. I'm not sure what exactly those limitations are at this point, but, by adjusting a couple of the C/H/S settings when using format to set up the disk I was able to get it to work correctly. So, I now have Solaris 9 installed on qemu-system-sparc with OpenBIOS! I'll probably go back to Solaris 8 as that one has a free binary license while Solaris 9 is a commercial license, IIRC. I do own a Solaris 9 commercial license, but I like the free idea, better. Anyway, now I'm on to an issue with networking - I've used the following two qemu network parameter combinations: -net nic -net tap,ifname=tap0 -net nic -net user In the first instance, tap0 was configured on my Linux box and added to my bridge br0. In both cases the Solaris system is unable to obtain a DHCP address - the DHCP client times out. Not sure if I should be using a different parameter set, or if this is another area that needs some work either for OpenBIOS or qemu? -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

[PATCH] RFC: Change ofmem_common.c to set memory translation properties by reference
by Mark Cave-Ayland 04 May '11

04 May '11

Hi folks, The attached patch changes OFMEM so that instead of allocating new space within the Forth dictionary every time the /memory and /virtual-memory available/translations nodes are updated, we simply change the property to point directly to a static buffer. This has the effect of saving substantial amounts of memory during OpenSolaris 10 boot (in fact the final dictionary size after boot is now < 256K once again). Blue/Andreas: please could you take a look at this patch and make sure it doesn't break anything in your SPARC64/PPC tests? On the plus side, with this patch applied Milax gets to the end of its natural boot without crashing giving the following output: OpenBIOS for Sparc64 Configuration device id QEMU version 1 machine id 0 kernel cmdline CPUs: 1 x SUNW,UltraSPARC-IIi UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.0 built on Oct 14 2010 20:18 Type 'help' for detailed information Trying cdrom:f...

After booting the install successfully from the Solaris ISO/CDROM and getting through the initial configuration (on both Solaris 8 and 9), the install fails trying to label the hard drive. First, I see the following during the installer boot: WARNING: /iommu@0,10000000/sbus@0,10001000/espdma@5,8400000/esp@5,8800000/sd@0,0 (sd0): corrupt label - wrong magic number Then, after doing the system identification, I get the following: One or more disks are found, but one of the following problems exists: > Hardware failure > Unformatted disk. At which point I get dropped to a shell. If I try to use the format command from the shell, format cannot auto-configure the disk. Even if I try manually setting C/H/S parameters (either at qemu run time or in the format command), it does not seem to want to use the disk. This seems to happen whether I'm using an LVM volume or a file-based disk. Also, seems as though all changes are lost on the disk when I exit format and then immediately go back in. Ideas? Any further help/input/debugging I could provide? -Nick -------- This e-mail may contain confidential and privileged material for the sole use of the intended recipient.

[commit] r1037 - in trunk/openbios-devel: config/examples drivers
by repository service 27 Apr '11

27 Apr '11

Author: mcayland Date: Wed Apr 27 21:20:10 2011 New Revision: 1037 URL: http://tracker.coreboot.org/trac/openbios/changeset/1037 Log: Fix up LANCE ethernet DMA mapping under Solaris 8 on SPARC32. It seems that Solaris doesn't set up a DMA mapping for the LANCE DMA buffers and hence must inherit this from OpenBIOS. To make things more complicated, Solaris appears to assume that the buffers are fixed at 0xff000000 rather than detecting this information from the OpenBIOS IOMMU pagetable before switching. Mimicking this behaviour with a fixed location allows Solaris 8 to correctly use the network card under QEMU.

Otherwise the patch looks OK.
