The fix is for OpenBIOS to not allow the client to POP() more items from the stack than were there before the CIF call, for which I have a local patch whilst I wait for the QEMU guys to update their git repository from our SVN. Please try the attached and let me know if you manage to get any further. ATB, Mark.

Can init-program cause code to run?
by Mark Cave-Ayland 31 Dec '13

31 Dec '13

Hi all, I've recently seen a couple of test cases in SPARC64 Forth bootloaders whereby during execution, the bootloaders call "init-program" on an address and expect it to start executing immediately. My understanding from reading the IEEE1275 specification is that "init-program" merely sets up the execution state ready for it to be invoked by "go" and doesn't start execution itself - or could it be that because "go" is currently running then "init-program" detects this and automatically re-invokes "go" on the new payload itself? ATB, Mark.

Qemu/OpenBIOS 64-bit
by Nick Couchman 29 Dec '13

29 Dec '13

So, I have Solaris 9 working inside a qemu-system-sparc (32-bit) environment with OpenBIOS, but no such luck getting 64-bit Solaris (8/9/10/11) to boot. I've attached boot output from Solaris verions 8, 9, 10, and 11. Getting a later version (10+) to work would be nice, since it seems that at least up to Solaris 9 doesn't support CPU power management, which means the qemu-system-sparc process runs at 100% CPU usage constantly. If I need to hook up a debugger and do more digging, I can...just let me know. Thanks, Nick -------- This e-mail may contain SEAKR Engineering (SEAKR) Confidential and Proprietary Information.

Qemu, OpenBIOS, and HostID
by Nick Couchman 29 Dec '13

29 Dec '13

First, thanks to everyone who has worked to get OpenBIOS up to its current functional level over the past couple of years. I'm using Solaris 9 on OpenBIOS with pretty good success these days, which is awesome. I do have a question about Qemu, OpenBIOS, and the Solaris hostid. It seems that, currently, when booting Solaris with Qemu, the host ID is set to "80000000." As far as I can tell, this isn't near correct - according to all of the documentation I've read, the host ID should be calculated based on the machine type, and some portion of the MAC address. This may be the wrong forum in which to ask this, but I'm wondering if someone could shed light on why it shows up that way, and if there's a way in OpenBIOS via the PROM/NVRAM data to set the host ID to something a little bit closer to normal? Thanks! -Nick -------- This e-mail may contain SEAKR Engineering (SEAKR) Confidential and Proprietary Information.

Probably a dumb question - Intel MB DG45ID
by Philip Rhoades 28 Dec '13

28 Dec '13

People, I have been on this list for some time lurking - just because I think it is interesting that a bit of firmware can allow hardware to be actually useful! I haven't done more than read the occasional post that was of interest but the thought occurred to me again about replacing the BIOS that is on my current machine with something that is open so I went back to the OpenBIOS home page but was a bit puzzled to see on the Download page: "Do not try to put OpenBIOS in a real boot ROM, it will not work and may damage your hardware!". After a little more looking around I am still confused - the ultimate aim of this software is to eventually allow people to replace their proprietary BIOSes right? I have an Intel MB DG45ID but I couldn't Google much overlap with OpenBIOS . . Thanks for any enlightenment! Regards, Phil. -- Philip Rhoades GPO Box 3411 Sydney NSW 2001 Australia E-mail: phil(a)pricom.com.au

Yes, if things do try and access the NVRAM directly then that would definitely be a better solution (I had no idea that QEMU did this until I read your previous email!). It's not particularly on my radar at the moment as I'm back deep in SPARC64-land, but I'd be happy to support anyone that did come up with something suitable. ATB, Mark.

[commit] r1246 - trunk/openbios-devel/drivers
by repository service 20 Dec '13

20 Dec '13

Author: mcayland Date: Fri Dec 20 11:45:54 2013 New Revision: 1246 URL: http://tracker.coreboot.org/trac/openbios/changeset/1246 Log: tcx/cgthree: remove hard OpenBIOS dependency from driver Since QEMU 1.7, the OpenBIOS TCX framebuffer FCode ROM is made available to Open Firmware upon boot. However, this causes a boot failure for people who use a Sun OBP firmware with QEMU since the FCode throws an exception trying to access some OpenBIOS-specific variables. This causes an invalid device node to be created in the tree, causing a crash on boot as reported by Peter Bartoli and Artyom Tarasenko. Fix both drivers so that if OpenBIOS is not detected, we fall back to the QEMU framebuffer defaults of 1024x768x8 which should generate a valid device node and avoid the crash.
