testing Max OS X boot on latest trunk (revision 1080)
by Amadeusz Sławiński 28 Feb '13

28 Feb '13

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).

[PATCH] ppc: Don't do relative branches from relocated memory
by Andreas Färber 25 Feb '13

25 Feb '13

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 24 Feb '13

24 Feb '13

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 23 Feb '13

23 Feb '13

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.
