Hi all,
I am trying to enable PCI-e device pass-through mode with KVM, since
Juno-r2 board has PCI-e bus so I firstly try to use vfio to
passthrough the network card on PCI-e bus.
According to Juno-r2 board TRM [1], there has a CoreLink MMU-401 (SMMU)
between PCI-e devices and CCI bus; IIUC, PCI-
20 matches
