Hi Alex:
Recently I am interested in igd passthrough. On the 'igd-assign' text, I
don't understand why the lpc bridge need to be created ?
Looking forward to your reply. Thanks.
qemu/hw/vfio/pci-quirk.c
/* Create our LPC/ISA bridge */
ret = vfio_pci_igd_lpc_init(vdev, lpc);
if (ret) {
error_report("IGD device %s failed to create LPC bridge, "
"legacy mode disabled", vdev->vbasedev.name);
goto out;
}
/* Stuff some host values into the VM PCI host bridge */
ret = vfio_pci_igd_host_init(vdev, host);
if (ret) {
error_report("IGD device %s failed to modify host bridge, "
"legacy mode disabled", vdev->vbasedev.name);
goto out;
}
