Re: [Qemu-devel] [ADD] PPC processor emulation

[Raymond W . Lucke IV]

Hmm...

My goal is not necessarily to run Linux binaries directly on Darwin, 
that would truly mean doing Linux syscall emulation. But from what I 
understand, trying to make vl would actually be in a number of ways 
much simpler, since it does not translate syscalls one by one, but 
instead the operating system being executed handles it's own, and calls 
virtual hardware provided by vl.
