I'm lightly investigating this option. I've tried both:
~/sfw/qemu-4.2.1/bin/qemu-system-ppc64 -s -S -cpu e6500 -nographic -m
2g -M ppce500 -kernel hello.exe -D log -d in_asm,cpu,int
and
~/sfw/qemu-4.2.1/bin/qemu-system-ppc64 -s -S -cpu e6500 -nographic
-serial mon:stdio -m 2g -M mpc8544ds -kernel hello.exe -D log -d
in_asm,cpu,int
E.g. machines either ppce500 or mpc8544ds and in both case the code hang
up in bsps/shared/dev/serial/ns16550-context.c:534 which is:
532 /* Wait for transmitter holding register to be empty */
533 do {
534 status = get( port, NS16550_LINE_STATUS);
535 } while ((status & SP_LSR_THOLD) == 0);
536 }
so I'm hitting infinite loop here since serial is badly configured
probably. Otherwise I think this stacktrace shows a bit of hope that
something is really working:
Program received signal SIGINT, Interrupt.

Now, the question is how to make serial to work well. Qemu supplied
device tree text representation is also attached.
Thanks,
