If you know of anyone who is working on this or of pitfalls I should
consider before jumping in, please let me know.
Is the instruction set virtualizable?
FWIW it's not. Kernel mode is used based on an address offset of the IP.
Since you'd want to have your guest running in user mode, you're pretty
much lost there.
I guess that would qualify as a pitfall. Thanks Avi and Alex.
After thinking about this some more, I think this means we can't run
an unmodified guest. It should be possible to build the guest kernel
to run in supervisor or user mode/address space.
I'm new to MIPS, so I'm still looking for other challenges in virtualizing
the instruction set.
Hi Dale, how is this going?
