[Barrelfish-users] Barrelfish-users Digest, Vol 33, Issue 2

[Matt Horsnell]

Hi Kournilios,

I think Zeus, currently interning with us at ARM, will follow up with a more informed email detailing some of the issues we've identified in trying to get the barrelfish tip running on the gem5 tip.

My personal input would be to try and persuade you to settle on supporting the Versatile Express EMM platform as the basis for the gem5 port. This is the default platform ARM is currently supporting through our efforts with gem5 and it is likely to remain the most stable going forward. As a reference point this will also give you the ability to make comparisons directly to Linux/Android (those kernels being actively maintained by ARM and Linaro for EMM).

In terms of actual hardware that is a political decision best left to the community. I know you guys are already using the Pandaboards and that there are a number of other relatively cheap platforms available (Samsung's Arndale board being a recent example). A good guide explaining how you would go about porting the OS to another board would probably be more useful than supporting more than one board.

As mentioned in the past, I am happy to help/facilitate/support where I can,

// Matt
