I've applied these on top of my MacOS virtual memory branch at
https://github.com/mcayland/qemu/commits/q800.upstream2-vm and I can confirm that
MacOS 8.1 now boots here with virtual memory enabled :)
Possibly it might be worth including a tidied-up version of the "WIP: target/m68k:
always exit_tb when changing sr with andi/ori/eori" commit from that branch which is
also related to switching between supervisor and user modes under MacOS. Shall I tidy
it up and send it to the list?
ATB,
Mark.
I've compiled the branch mentioned above with a fully updated MSYS2 on windows. The executable hangs when running Mac OS 8 with Virtual Memory enabled. On a fast machine I see Error 7 as before, on a slower machine, the boot screen just hangs with no error shown. A Linux build does work, also on the slower machine.
Best,
Howard
