[Qemu-devel] [PATCH 00/17] m68k: add partial Motorola 680x0 support

[Laurent Vivier]

This series of patches is a port to Qemu 0.10 of Andreas Schwab M68K patch
to support Motorola 680x0 CPU family.

It has been tested with some commands from a debian m68k lenny disk.

Commands like "uname", "date", "ls", "more", "grep" work well.

Ohh cool, now I just need to add a real system target to test my Haiku
port :)

Has there been any progress on this?  (Or current versions I can test?)

I have a cross compiler, root filesystem, and kernel built for m68k, but no 
test environment.  Charles Stevens got a system image running under aranym, 
but that has several limitations (such as no serial I/O, which makes a serial 
console problematic), and I'm testing all my other targets on qemu.

All the current system images are coldfire, which I haven't played with because 
I haven't done any nommu targets yet.  Presumably I could shoehorn a real m68k 
into a coldfire system emulation, assuming I could beat a relevant .config out 
of the kernel...

I try to keep in sync this git tree:

http://gitorious.org/qemu-m68k/qemu-m68k

But the FPU need a lot of rework.

Only linux-user qemu is supported.

Regards,
Laurent
