Some sort of Broadcom chipset, I think. Full dmesg and lspci output are
appended.
The PCI bridge does mention MSI, so maybe it does support it. Would
using the DMA from the host mean that the guest system couldn't use the
DMA controller at all? All of the channels share the same interrupt line
on the guest. I need one channel on the DMA controller on the guest to
do realtime transfers from some data processing FPGAs on the board.
This stuff is never easy, is it? :)
Thanks for the help so far, I really appreciate it.
