[RFC PATCH 0/2] implement device nodes needed by xnu kernel
by Amadeusz Sławiński
Following patches implement /uni-n and /pci/mac-io/via-cuda/power-mgt
With them xnu kernel no longer panics when recognizing machine type.

Seems like someone checked moderation queue, it's old message, from
december. I did resend it

testing Max OS X boot on latest trunk (revision 1080)
by Amadeusz Sławiński
Here are results of my testing booting OS X on latest trunk
Logs in attachment
Not patched ones (fails without get-key-map):
10.0.log
10.2.log
10.4.log
Patched with gsoc get-key-map patch:
10.0-gkm.log
10.2-gkm-panic.log
10.4-gkm.log
Patched with gsoc divide by 0:
10.2-gkm-dvb0.log
Logs from patched boot without CIF:
all-without-cif.log
10.2 ones show that there is need for some solution regarding division
by 0, some notes from my talks with Mark:
My g5 machine returns 0 when dividing by 0, no warnings are printed:
0 > 0 0 / ok
1 > . ok
0 > 0
0 > 2 0 / ok
1 > . ok
0 > 0
Question is how to implement it, or maybe just use gsoc patch?
Also it seems that Mac OS X seems to provide it's own fill-rectangle and draw-rectangle
it prints:
FILL-RECTANGLE isn't unique.
and also similar message when I apply gsoc draw-rectangle patch
so it seems that this one isn't needed
Another problem is that it seems to be unable to open/load kernel.
On graphic side of things it seems to draw things better than with gsoc
patches, graphics are not weirdly resized, but there is not much to see
except boot folder graphic (10.0)/white apple(10.2, 10.4).

[commit] r1100 - trunk/openbios-devel/packages
by repository service
Author: mcayland
Date: Thu Feb 28 00:06:10 2013
New Revision: 1100
URL: http://tracker.coreboot.org/trac/openbios/changeset/1100
Log:
mac-parts.c: Fix /packages/mac-parts boot when the package arguments are empty.
Commit r1072 removed a couple of NULL pointer checks for package arguments,
however if the arguments are empty in Forth then they are converted back to a
NULL pointer which causes an exception when dereferenced.
Add the checks back in which fixes boot of the debian_lenny_powerpc_small.qcow2
test image with quik once again. Based upon an earlier patch by Alexander Graf

[PATCH] ppc: Don't do relative branches from relocated memory
by Andreas Färber
On startup, OpenBIOS copies exception vectors to 0x00000000.
Therefore jumps cannot be performed relative to the compile-time address
to outside the relocated exception vectors.
QEMU's g3beige and mac99 did not run into this so far, but prep does.

Macintosh device tree
by Programmingkid
I am investigating the device tree of the mac99 model. It looks like it is wrong. The part that I am concerned with is the via-cuda node. Both my iMac and iBook don't even have a via-cuda. They both have a via-pmu@16000 node. I'm hoping someone has an original blue and white PowerMac G3. I would like the full device tree printout from it. The question I am trying to answer is does any newworld Mac have a via-cuda? If they don't, we know that it should be changed to a via-pmu@16000 node.

[PATCH] Fix mac label whole partition case
by Alexander Graf
Commit r1072 removed the check for NULL pointer strings in the mac
partition lookup. However, without that check we would end up dereferencing
this string pointer later, breaking my Debian Lenny test image.
Add the check back in. This fixes Lenny with quik again.
