Re: [Nubus-pmac-users] Porting to Quadra 700 with PowerPC 601 Upgrade Card

[Jeremiah H. <jjh...@gm...>]

The two things that need to be looked at and replace m68k platform code and
either rewrite or move into the powerpc kernel are the drivers for the ADB
controller and the graphics files are in dirvers/macintosh/via-macii.c for
the ADB and drivers/video/macfb.c. My C skills are pretty elementary but
from my basic understanding getting this going we will basically have to
make the drivers understand the PPC IRQ setup. Of the two I think the ADB
will less work since ADB already exists on the PowerPC side should take too
much add the MacII support. I know nothing about graphics drivers but the
ValkryieFB exists on both m68k and PowerPC aswell maybe there is some clues
there.  We could at least get around no onboard video since the kernel
seems to already support nubus cards. I was planning on picking up a HPV
card anyhow, that way I can see if the kernel is actually booting after
bootx kicks off the process.
