When running qemu-system on Darwin, the vcpu processes guest code,

I don't get to see anything on the cocoa screen.
Out of curiosity, does it work with iothread?
Seems to work with -nographic, yes. With cocoa it doesn't seem as
happy :o. It certainly gets a lot further than without.
-nographic has issues with --enable-io-thread, too. It gets further
than Cocoa though before it bails out.
Actually, I'm still seeing issues with your patch as well. Might be
multiple independent issues that have cropped up?
In particular I'm observing that AIX on qemu-system-ppc - as reported
by Kenneth - doesn't reach the point where it tells us the 32-bit CPU
is incompatible. With your patch it is now possible to exit the QEMU
process though.
Any ppc64 guests don't even seem to enter OpenBIOS at all, whether
OpenBIOS/ppc or OpenBIOS/ppc64.
It seems there is a DSI exception when turning on the MMU in OpenBIOS
(before any serial output occurs). Does that ring a bell with you,
some pSeries change maybe?
The pSeries changes did some cleanups to the MMU code, yes, but they
looked pretty much sane to me. Are you running on a ppc64 host? Maybe
there's some undefined corner case shifting happening :).
