No, but I think I'm doing that right. I put the little bit of code that
sets up the request below, so please let me know if I'm not. Also, I
think I figured out the problem. I have a function to send a message
out, but it was always using timing mode. The -atomic- simple CPU was
apparently upset about getting a timing callback. Now that that's fixed
it seems to be working fine.

PacketPtr
prepIntRequest(const uint8_t id, Addr offset, Addr size)
{
RequestPtr req = new Request(x86InterruptAddress(id, offset),
size, UNCACHEABLE);
PacketPtr pkt = new Packet(req, MemCmd::MessageReq,
Packet::Broadcast);
pkt->allocate();
return pkt;
}
