Hi,
I'm looking at how easy it would be to boot the x86-64 version of the
Barrelfish OS on m5 (http://www.barrelfish.org/ says more about the project,
although the most recent source release is now getting a bit out of date).
The OS itself runs on the bare metal. It has fairly limited
Hi Nate, Gabe, thanks for the pointers!
I've got a simple Barrelfish system now running. It gets as far as booting 1
core, starting various system processes on them, and running a user-mode test
app. My current changes are a mess -- both the changes to m5 and to Barrelfish
-- so I'll need to
could probably recreate them from your descriptions if you don't want to
for some reason.
Thanks again for letting us know about the bugs, and best of luck moving

being truncated. I was seeing IsLastMicroop being lost, leading to
assert-fails (m5.opt) /
