[Qemu-devel] [RFC 00/13] hw/m68k: add Apple Machintosh Quadra 800 machine

[Laurent Vivier]

I'm rebasing some of these patches for seven years now,
too many years...

It's an RFC because things have changed in QEMU in seven years,
for instance the VIA has a new implementation (mos6522) introduced
by Mark Cave-Ayland and I didn't rework my implementation to
fit into this new one (any volunteers?), display has some glitches,
ADB devices are not identified correctly.

if you want to test the machine, I'm sorry, it doesn't boot
a MacROM, but you can boot a linux kernel from the command line.

You can install your own disk using debian-installer, with:

    ...
    -M q800 \
    -serial none -serial mon:stdio \
    -m 1000M -drive file=m68k.qcow2,format=qcow2 \
    -net nic,model=dp83932,addr=09:00:07:12:34:57 \
    -append "console=ttyS0 vga=off" \
    -kernel vmlinux-4.15.0-2-m68k \
    -initrd initrd.gz \
    -drive file=debian-9.0-m68k-NETINST-1.iso \
    -drive file=m68k.qcow2,format=qcow2 \
    -nographic

If you use a graphic adapter instead of "-nographic", you can use "-g" to set 
the
size of the display (I use "-g 1600x800x24").

You can get the ISO from:

https://cdimage.debian.org/mirror/cdimage/ports/9.0/m68k/iso-cd/debian-9.0-m68k-NETINST-1.iso

and extract the kernel and initrd.gz:

guestfish --add debian-9.0-m68k-NETINST-1.iso --ro \
          --mount /dev/sda:/ <<_EOF_
copy-out /install/cdrom/initrd.gz .
copy-out /install/kernels/vmlinux-4.15.0-2-m68k .
_EOF_

The mirror to use is: http://ftp.ports.debian.org/debian-ports/
when it fails, continue without boot loader.

In the same way, you can extract the kernel and the initramfs from the qcow2
image to use it with "-kernel" and "-initrd":

guestfish --add m68k.qcow2 --mount /dev/sda2:/ <<_EOF_
copy-out /boot/vmlinux-4.15.0-2-m68k .
copy-out /boot/initrd.img-4.15.0-2-m68k .
_EOF_

and boot with:

   ...
   -append "root=/dev/sda2 rw console=ttyS0 console=tty \
   -kernel vmlinux-4.15.0-2-m68k \
   -initrd initrd.img-4.15.0-2-m68k
