My workaround at this end is to just revert openbios-ppc to the earlier version. I still think that bisecting to find the specific commit that broke it would be informative, but your repository's move to /trunk at commit 470 essentially wiped all repository history before that. Your development page doesn't say how to download the old versions, just the ones under "trunk": http://www.openfirmware.info/OpenBIOS Nor does your repository viewer view anything before 470 from the little pull- down menu: http://tracker.coreboot.org/trac/openbios/browser/trunk/openbios-devel?rev=… http://tracker.coreboot.org/trac/openbios/browser/trunk/openbios-devel?rev=… I guessed how to get the repository viewer to show me the earlier versions: http://tracker.coreboot.org/trac/openbios/browser/openbios-devel?rev=469 But this doesn't work: $ svn co -r 469 svn://openbios.org/openbios/openbios-devel svn: File not found: revision 480, path '/openbios-devel' Then again, I can always bisect by downloading tarballs from your repository viewer... Eh, why not. For easy cut and pasting, my build reproduction sequence is: chmod +x config/scripts/switch-arch config/scripts/switch-arch cross-ppc PATH=~/firmware/firmware/build/cross-compiler-powerpc/bin:$PATH \ make TARGET=powerpc- sudo cp obj-ppc/openbios-qemu.elf /usr/local/share/qemu/openbios-ppc 469 exhibits the bug, so it's before that. I believe 450 is the "known good" version, so let's try 460... Bug. 455... Bug. 452... Bug. 451... Works. So the bug was introduced (or at least triggered) by revision 452: http://tracker.coreboot.org/trac/openbios/changeset/452/openbios-devel Anything in there look broken to you? Rob P.S. Please at least put up a link to this on your development page: http://tracker.coreboot.org/trac/openbios/browser/openbios-devel?rev=469 Right now earlier versions of your repository are completely inaccessible to newbies like me...

Diagnostics support

by Robert Reif

How much diagnostics support is already in OpenBIOS and what would it take to add something like sun's OBDiag. Has anyone ever tried running a sparc32 OpenBIOS image on real hardware?

The kernel makes the equivalent of the following calls to OF interface: finddevice("/") = 0x11d5c finddevice("/chosen") = 0x1197c finddevice("/openprom") = 0x11b3c getprop(0x11b3c, "model", 0x78efeb0, 0x40) = 0xf getprop(0x11d5c, "stdout", 0x78efea0, 0x4) = 0x4 instance-to-path(0x86ea0, 0x12ad0dc, 0xff) where it crashes because memmove overwrites all memory. But where does this 0x86ea0 come from?
