[Qemu-devel] Porting QEMU to run on Plan9

[Qemu-devel] Porting QEMU to run on Plan9

We are graduate students from CMU, working on an OS project. We want to port
QEMU so it can run on Plan9 and Plan9 users can thus run Linux on Plan9 that
way.

Is there a porting guide to port QEMU to a new host OS ? Anyone have
suggestions on how to go about it?

Thanks,
Deepti & Bankim

Maybe

http://libvncserver.sourceforge.net/qemu/qemu-porting.html

can help you.

We had already visited that link. But it seems to us that the guide is for porting it to a new hardware platform, and not for porting it so it runs on a new OS. Are we wrong?

I'd start by hacking configure. It is a plain shell script (no autoconf 
here). I presume you do not want to port to a new CPU? Then you only have 
to add new code for Plan 9 (just look for "SunOS", and imitate one of the 
platforms). Note that you have to disable user mode (this can only work 
when the emulated OS has the same set of syscalls).

After you can run configure successfully, I'd just start fixing 
compilation errors until I am done.

You are not completely wrong. It was intended as a guide line on how to 
port to a new OS _and_ CPU. Since you are doing just half of that, the 
text behind the link should help you tremendously: if there is a problem, 
the document should help you understand how to fix it.
