Thanks, and yes I did see that thread. As my goal is just to use the
IP-over-myrinet driver in Dom0, this seemed like a feasible goal. At least,
as nothing in the discussion you referenced that said it would be impossible...
Anyway, I actually managed to get the GM kernel module and associated tools to
compile under xen-unstable (Dom0 kernel is a xenified 126.96.36.199 linux kernel).
I try to load the module, though, it gets this far:
<other gm messages>
GM: MCP for unit 0: L9 4K
GM: LANai rate set to 132 MHz (max = 134 MHz)
GM: Board 0 supports 2072 remote nodes
GM: Board 0 page hash cache has 32768 bins
GM: Board 0 has 1 packet interfaces.
GM: Allocated IRQ48
... and then my computer freezes. I am of coursenot should what to so at this
point, so if you've tried anything similar and gotten any results (or similar
failures) I'd be happy to hear it.
