These fixes greatly improve qemu booting on PPC - many Linux
distributions with kernel 2.4 now work. It's two big patches (one for
qemu, one for OpenHackWare) - let me know if someone prefers them broken
out into smaller pieces.
There's still some work to be done to get PREP in good shape as well as
a Linux 2.6 kernel to work well - expect some more patches in the near
future.
Highlights
* Real serial
* Correct PCI host bridge for PREP (wrong in Pearpc, Qemu and
OpenHackWare)
* -Werror building for OpenHackWare
* proper reboot
* HFS OpenHackWare now correctly traverses the B*tree - greatly improves
probability of booting *all* HFS based filesystems
* Many, MANY other fixes

+ - to -> too
+ - recurs -> recurse
+ - catched -> caught
+* HFS - Correctly descend right most nodes instead of giving up

+ - Don't probe partitions until after disk controllers are initialized
+ - Correctly exit out of pci_check_host()
+
+2005-01-27: version 0.3+msw:
+* OpenFirmware emulation:
+ - Recognize additional debian forth script.
+ - Deal with a kernel name which is quoted in the forth script.
+ - Boot off of first bootable partition on device (not last).
+ - Change reported machine type from PPC to PowerPC (fix for debian installer)
+ - Add PC Keyboard input support (PREP emulation).
+ - Add initial (broken) ADB keyboard support.
+ - Add serial port input support.
+ - Read input from any console with input available.
+ - Support firmware output to all consoles (VGA and Serial).
+* Partition management:
+ - Make partition search (Apple_bootstrap and the like) case-insensitive.
+* Misc:
+ - Add strncasecmp and tolower.
+ - Update copyrights.
+ - Cleanup code for GCC 3.2 warnings.
+ - Fix typo in BIOS ld script.

Very good ! Have you looked at Darwin and Mac OS X ? I feel QEMU (and
OpenHackWare) are very close to launch them: at least all the hardware
emulation is there. I am unable to look at the problem because I don't
have an easy way to recompile the Darwin kernel to insert debug
messages... and another problem is that I don't have the time :-)

Should be "emulating PPC" rather than "booting on PPC".

Thanks - I should mention that Matthew S. Wood did quite a bit of the
work.

I haven't looked at them. I'd like to try OSX, but I don't have a copy
and haven't bugged the right person for one. Hopefully I'll get around
to it, however it isn't as high of a priority as generl PPC emulation.

I might be in the same boat, unfortunately. I'm mostly hoping that if
the general problems get fixed then it will be easier for someone to
pursue the special case problems. If qemu/OpenHackWare can be show to
be generally solid and work well for linux/ppc, then hopefully some
that's motivated to have OSX or Darwin will give it a go.
I'm interested to know when the patches will be applied to Qemu and
OpenHackWare or when I'll get feedback regarding what needs to be done
differently.
Thanks.

Hi.
Thanks for the work. I need to take a close look of your patches because
I completely restructured OHW. For example, HFS code is quite different
in my working repository (but still have problems on some fs)...
I have a few remarks about the patches:
* in Qemu:
pci_enabled option should not be used for PPC emulation: we don't
emulate MCA, so PCI is mandatory for PREP and the Mac target is Mac99
which also always have PCI.
The rest of the patch seems OK, imho.
I can't compare OHW for now, as it seems that most of the patch is
cosmetic (blanks, tabs) and as most files have changed. Could you please
regenerate the patch using:
--ignore-all-space --ignore-blank-lines --ignore-space-change --minimal
-p
options to make it easier to read ?
I'll send you my current working version of OHW by mail so you can
compare and see where your patches can still apply easily (while I'll
try too...).

Okay. I'm shooting in the dark, somewhat. I don't really have any
PREP/CHRP hardware - I'm just going off of some random lspci outputs I
have found with Google. I do know, however, that the PREP PCI host
bridge is incorrect in Pearpc, Qemu and OpenHackWare.
Does anyone have a Linux 2.6 /sys tree for PREP and CHRP? That would be
most useful for getting all the ISA, PCI and other devices correct.

I'm a bit confused. I closely reviewed the patch prior to sending and I
didn't notice any instances of whitespace-only diff. There are,
however, many lines of spelling changes. :) controler -> controller,
recurs -> recurse, to -> too, etc..

I'll look for it.

Oh well, I looked closer, and you're absolutely right, there are lots of
typo I didn't saw at first sight.... I'm sorry about my mistake.
But I would still appreciate a diff with -p option, then I have the
function name with the diff, which may helps when code has been
splitted...

Adds a Motorola Raven PCI host bridge. Without this none of the PCI
