Yep, I have no idea. The last time I tested this it worked (although I might not have tested interrupts) and now it doesn't. Nothing has changed in the series, my guest software has changed though. I can see the root complex, but no devices underneath it. Sorry for the confusion with the MicroSemi PCIe root complex. I think I'll just drop this patch. It doesn't work for 32-bit guests, but I would like to model the hardware so I don't want to change the addresses. We can revisit this in the future along with the gpex high MMIO support and USB support. Alistair > > Alistair > > > > > Logan
