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.

QEMU OpenBIOS booting?

by Steven Noonan

Hi folks, I've been trying to use OpenBIOS with QEMU, and I've had trouble getting it to boot any PowerPC-based OS discs (Linux, Mac OS X, etc). OpenBIOS just doesn't seem to find anything bootable. If I try booting QEMU with -nographic, I get this output (I get the same with a self-built openbios-qemu.elf from the OpenBIOS SVN as well): ---- snip ---- >> ============================================================= >> OpenBIOS 1.0 [Apr 12 2009 00:55] >> Configuration device id QEMU version 1 machine id 1 >> CPUs: 1 >> Memory: 128M >> UUID: 00000000-0000-0000-0000-000000000000 >> CPU type PowerPC,970FX Welcome to OpenBIOS v1.0 built on Apr 12 2009 00:55 >> ELF - yaboot_startup: Entering boot, no path >> ELF - try_bootinfo: Trying hd:0,ppc\bootinfo.txt >> ELF - try_bootinfo: Can't open hd:0,ppc\bootinfo.txt >> ELF - try_path: Trying hd:2,\ofclient >> ELF - try_path: Can't open hd:2,\ofclient >> ELF - try_path: Trying hd:2,\yaboot conf=hd:2,\yaboot.conf >> ELF - try_path: Can't open hd:2,\yaboot >> *** Boot failure!

Has such a bug been confirmed? I was trying to find the bug myself (I am an experienced C/C++ programmer), but the bug seems to be subtle, and my lack of familiarity with the code base doesn't help much. I've been trying to figure this out for 7 hours straight now... Any advice or other help would be much appreciated! - Steven

Cross-compiling and testing sparc64 on Mac OS X

by Andreas Färber

Hello guys, It's awesome seeing you've made some progress towards emulating Solaris/sparc64! However trying myself, compiling on Mac OS X (after making sure that NEED_INT128_T is defined) fails with the following error: HOSTCC host/kernel/bootstrap.o In file included from ../include/openbios/sysinclude.h:7, from ../kernel/bootstrap.c:9: /usr/include/stdlib.h:267: error: syntax error before ‘arc4random’ make[1]: *** [host/kernel/bootstrap.o] Error 1 The return type of arc4random is u_int32_t, which is defined (in my case) in <ppc/types.h>. Not sure what goes wrong there. I thought it could be a name clash with OpenBIOS' __TYPES_H (malc would be furious!), but - luckily - Apple uses __TYPES_H_ for their _types.h. Anyway, not having these functions declared by defining _POSIX_C_SOURCE made the compilation proceed with only one warning: HOSTCC host/kernel/bootstrap.o ../kernel/bootstrap.c: In function ‘interpret_source’: ../kernel/bootstrap.c:529: warning: implicit declaration of function ‘strcasecmp’ If I symlink .../share/qemu/openbios-sparc64 to .../obj-sparc64/ openbios-builtin.elf (or copy it over) I get this at runtime: qemu: fatal: Trap 0x0010 while trap level (5) >= MAXTL (5), Error state pc: 0000000000004200 npc: 0000000000004204 General Registers: %g0: 0000000000000000 %g1: 0000000000000000 %g2: 0000000008000000 %g3: 0000000000000000 %g4: 0000000000000000 %g5: 0000000000000000 %g6: 0000000000000000 %g7: 0000000000000000 Current Register Window: %o0: 00000000ffe00000 %o1: 00000000ffe01000 %o2: 000001fff0100000 %o3: 000001fff0000000 %o4: 0000000000000000 %o5: 0000000000000000 %o6: 0000000000000000 %o7: 000001ff00000000 %l0: 0000000007e80000 %l1: 000001ff00000000 %l2: 000001fff0080000 %l3: 0000000000000000 %l4: 0000000000000000 %l5: 0000000000000000 %l6: 0000000000000000 %l7: 0000000000000000 %i0: 0000000000000000 %i1: 0000000000000000 %i2: 0000000000000000 %i3: 0000000000000000 %i4: 0000000000000000 %i5: 0000000000000000 %i6: 0000000000000000 %i7: 0000000000000000 Floating Point Registers: %f00: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f04: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f08: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f12: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f16: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f20: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f24: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 %f28: 000000000.000000 000000000.000000 000000000.000000 000000000.000000 pstate: 0x00000015 ccr: 0x99 asi: 0x00 tl: 5 fprs: 0 cansave: 6 canrestore: 0 otherwin: 0 wstate 0 cleanwin 6 cwp 7 fsr: 0x00000000 ../qemu-solaris-sparc.command: line 3: 3289 Abort trap / Users/andreas/Q/latest/bin/qemu-system-sparc64 -nographic -boot d - cdrom /Users/andreas/Q/sol-10-u3-ga-sparc-dvd.iso This looks different from what you've posted and is identical with QEMU's version of openbios-sparc64.

PATCH v2: Rework CIF interface to handle parameters in reverse order

by Mark Cave-Ayland

Hi everyone, Here is a second version of the patch which attempts to reverse the argument order of the CIF Forth words so that they can be called correctly from both Forth and C. The patch is fairly straightforward; probably the only unexpected part is the need to rename the existing /openprom/client-services "claim" and "release" words to "cif-claim" and "cif-release" respectively. This is because we need to use the "claim" and "release" words in forth/system/ciface.fs to reverse the argument order before calling the real underlying words. I've tested this on a FC12 PPC CD as well as my SPARC64 Milax CD and with this version of the patch, the CIF words are called correctly in both cases. I'd like to apply this reasonably soon, so please can people test on their setups to make sure it doesn't break anything?

OpenBIOS built in Mac OS X?

If so, how? Every attempt I made has failed. I'm using GCC 4.0.1. Could it be a problem with my compiler version?

RFC: fcode-utils portability

by Andreas Färber

Hello, When compiling the FCode utils on Mac OS X v10.5 I got an error when stripping. A workaround was to run `make STRIP=:`, not stripping at all. I now figured out that it's about the -s option: -s is short for -- strip-all in GNU strip but in Apple's strip -s references a text file with a list of symbols to preserve. I didn't spot an obvious equivalent to --strip-all. http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPa… Since the fcode-utils use pure Makefiles without prior art of platform- based decisions, I am wondering how to best supply a patch... Should the hardcoded -s be moved to a new STRIPFLAGS variable or into STRIP itself? And more important, how would we set either variable based on platform? Do we assume GNU make so that we can get the platform via $ (shell sh - c 'uname -s 2>/dev/null') or similar, as seen in Git? Creating a configure script seems like overkill for such a tiny fix. Thanks, Andreas

feature request

by G 3

There should be a 'make' command option that builds only the qemu target, and not the openbios-unix target. Something like this is what I have in mind: make -qemu_only Whenever I try to build OpenBIOS, I receive a whole bunch of errors with the unix target, but not with the openbios-qemu.elf target for some reason.

PPC cross-compiler defaults to 'powerpc-linux-gnu-' prefix

by Mark Cave-Ayland

Hi all, While setting up a PPC cross-compiler environment for OpenBIOS, I noticed that the default cross-compiler prefix is set to 'powerpc-linux-gnu-' as opposed to 'powerpc-elf-'. Is there any particular reason that we need the linux platform version, instead of the elf version which is used by SPARC? The reason I ask is that the Linux platform version is much much harder to compile as you need an extra set of glibc headers and have to bootstrap the gcc build by hand in order to produce the working final compiler. On my tests here everything seems to work fine with just the 'powerpc-elf-' prefix as far as I can tell.
