With the addition of PHB hotplug, we have a static number of DRCs that can be used to handle hotplug/unplug operations on our PHBs, and need a consistent way to map PHBs to these connectors, and assign a unique identifiers for the connectors. This patch adds a drc_id property for that purpose. Signed-off-by: Greg Kurz <groug@kaod.org> --- hw/ppc/spapr_pci.c | 1 + include/hw/pci-host/spapr.h | 2 ++ 2 files changed, 3 insertions(+)
