The mac99 machines always have a USB controller. Usually not having one around
doesn't hurt quite as much, but Mac OS 9 really really wants one or it crashes
on bootup.
So always add OHCI to make it happy.

According to the ISA setting the Rc bit on mtspr is undefined behavior.
Real 750 hardware simply ignores the bit and doesn't touch cr0 though.
Unfortunately, Mac OS 9 relies on this fact and executes a few mtspr
instructions (to set XER for example) with Rc set.
So let's ha

The lsxw instruction checks whether the desired string actually fits
into all defined registers. Unfortunately it does the calculation wrong,
resulting in illegal instruction traps for loads that really should fit.
Fix it up, making Mac OS happier.

Change the CUDA packet model to use a three-byte header as in real hardware.
Also add handlers for CUDA_COMBINED_FORMAT_IIC and CUDA_GET_SET_IIC.

This patchset greatly improves QEMU's ability to run Mac OS 9 on the mac99
machine, allowing progress past the bootloader and partial progress through
the load screen.

The current macio device implementation declares an interrupt that doesn't
seem to exist in the actual hardware or any other emulators. Mac OS 9 counts
the presence of this interrupt as a fatal error and progresses further without
it.

Hi all,
My name is Cormac O'Brien and I'm one of QEMU's student developers for Google
Summer of Code 2015. My project goal is to have Mac OS 9 running on both the
g3beige and mac99 machines by the end of the summer (it currently doesn't
boot on either). I'll be workin
While trying to implement OS 9 support on QEMU, I've run into the following
errors from the operating system:
g3beige:
*** MacOS: Fatal Error! (0xF3B37FDB) ***
