I have begun doing work with OpenBIOS. I was wondering if it is possible to compile OpenBIOS for PowerPC on Mac OS X? If not, what Linux distro should I use? Any advice would really help.

Solaris 9: failed boot with strange device names
by Mark Cave-Ayland Aug. 25, 2010

Aug. 25, 2010

Hi all, So given that the Fcode evaluator is sorted for Solaris 10, I thought I'd try my original Solaris 9 disk image again and was surprised to find that it didn't boot. Further investigation seems to show that strangely encoded device names are being passed into cif-open which is failing: : get-file ( 6000 ffe35870 27 ) 00000000ffe36378: fname>devname$ 3 > 2dup type /platform/OpenBiosTeam,OpenBIOS/ufsboot ok 3 > resume ok ( 6000 ffe35870 27 ) 00000000ffe36378: fname>devname$ ( 6000 ffe35ee8 2f ) 00000000ffe36380: ufs-fopen 3 > 2dup type cdrom:a,|platform|OpenBiosTeam,OpenBIOS|ufsboot ok 3 > resume ok ( 6000 ffe35ee8 2f ) 00000000ffe36380: ufs-fopen : ufs-fopen ( 6000 ffe35ee8 2f ) 00000000ffe360e8: drop ( 6000 ffe35ee8 ) 00000000ffe360f0: cif-open ( 6000 0 ) 00000000ffe360f8: (semis) : get-file ( 6000 ffe35870 17 ) 00000000ffe36378: fname>devname$ 3 > 2dup type /platform/sun4u/ufsboot ok 3 > resume ok ( 6000 ffe35870 17 ) 00000000ffe36378: fname>devname$ ( 6000 ffe35ee8 1f ) 00000000ffe36380: ufs-fopen 3 > 2dup type cdrom:a,|platform|sun4u|ufsboot ok 3 > resume ok ( 6000 ffe35ee8 1f ) 00000000ffe36380: ufs-fopen : ufs-fopen ( 6000 ffe35ee8 1f ) 00000000ffe360e8: drop ( 6000 ffe35ee8 ) 00000000ffe360f0: cif-open OFMEM: ofmem_claim_virt virt=ffffffffffffffff size=0000000000000200 align=0000000000000001 ( 6000 0 ) 00000000ffe360f8: (semis) It looks as if a special type of device-specifier is being passed into cif-open consisting of a device and argument, a comma, then the actual filename required with /s replaced by |s. Is this some kind of special syntax that needs to be taught to the dev word and/or cif-open words?

/packages/disk-label, /packages/sun-parts and /packages/misc-files
by Mark Cave-Ayland June 8, 2010

June 8, 2010

Hi folks, Is there some kind of specification for the above packages or are we free to design the interface as we choose? The reason I ask is that the current interposition order doesn't seem to be particularly logical. At the moment, the order goes like this for a CDROM: cdrom -> deblocker -> disk-label -> (misc-files or sun-parts or pc-parts) But I think it makes more sense to do this: cdrom -> deblocker -> disk-label -> (sun-parts or pc-parts) -> misc-files The reason for suggesting a change is because by placing misc-files directly after disk-label, all partition offsets have to be bubbled back up the chain using a series of get-info words to the device. If this could be reordered, it should be possible to remove most of this logic and simply pass the read/seeks back up to the parent. Otherwise, like at the moment, there is lots of code in misc-files that has to work out whether you are accessing a file or a partition directly and act differently which can't be a good thing.

I have a patch on my disk doing this for ISO9660 (not sure) but it is 7 months old and I don't know if it applies (and works) anymore.

In my current patch set, if no partition table is found then all I do is interpose misc-files under disk-label. As long as we bubble back up the packages methods, no changes are required. > Could you have a look to "CHRP binding" document, I think it describes some behaviors about this ? No, this is great! According to p.59 or thereabouts, disk-label conditionally interposes the filesystem package depending upon what it finds. This was the main part of the patch I was unsure about. I notice there is no mention of the sun-parts or pc-parts packages though; does anyone know where there is a copy of the SPARC platform bindings for more information?

Okay; I've just tried your patch and the crash is gone :) However, the boot now seems to freeze with "su: Cannot register IRQ 0" which didn't happen before the recent PCI fixes. I think that maybe another bug is being triggered somewhere now that the PCI bus is being handled more correctly.

[PATCH 00/10] encode-int related changes and pci bus scan amendment
by Igor V. Kovalenko May 27, 2010

May 27, 2010

These mostly are cleanups up to pci bus scan amendment changes. The pci bus scan is reworked, now we start with pci host bridge which will initiate primary bus scan. PCI-to-PCI bridges do the same. Although bridges are still mostly unusable in qemu due to missing address space remappings one can now put e.g. ide and vga on sun4u behind secondary bus and see it is found correctly and can be configured. With these applied my debian etch ppc installation still boots to shell, and helenos can get to video screen (with appropriate QEMU,VGA driver.) Another bonus point that on sparc64 recent linux "btext" boot console works (colors are a bit off though.) --- Igor V.
