i have a question about vfio , here is my description. i have 8 gpus in my server machine , but they are all behind a pcie bridge. when i make a vfio passthrough , i can't use the gpus in my guest os. dmesg shows the following message
[ 662.208072] vfio-pci 0000:87:00.0: irq 140 for MSI/MSI-X [ 725.761623] vfio-pci 0000:04:00.0: irq 140 for MSI/MSI-X i started two vm , one use 87 and another use 04, dmesg shows that they share the same irq 140 . is this normal ? i also saw the iommu groups, each gpu stays in a separate group， and with no other device in group. so this means ACS works correctly ? hope to get your helps !
