[Barrelfish] [Barrelfish-users] ARM port and programmable

The ARM port is at a fairly early stage. What is there is being developed on QMEU with an ARMv5TE ISA similar to the IXP/IOP instruction set. At some stage someone will hopefully take it forward to run an I/O card based on one of the these. The benefit of running on something like an IXP will really be felt if someone goes on to target the micro-engines.
For a contemporary system that did run on an I/O card there’s the Helios paper here: http://research.microsoft.com/apps/pubs/default.aspx?id=81154 The benefit of running code on this particular processor was slight. The processor has hardware acceleration for RAID operations and Helios wasn’t exercising this functionality in the paper.

Subject: [Barrelfish] [Barrelfish-users] ARM port and programmable network cards
I'm a currently working on a research proposal about multi-kernel ideals in network interfaces.
I noticed a paragraph under "Experience and future work" in your paper stating you where working on an ARM port to support programmable network cards.
In that context I was wondering if you had made any progress, or plans on how to integrate I/O devices like a network interface into your implementation of a multi-kernel operating system.
Any information would be greatly appreciated.
