List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: marcel@redhat.com, mst@redhat.com, imammedo@redhat.com, pbonzini@redhat.com, ehabkost@redhat.com PXBs do not support hotplug so they don't have a PCNT function. Since the PXB's PCI root-bus is a child bus of bus 0, the build_dsdt code will add a call to the corresponding PCNT function. Fix this by skipping the PCNT call for the above case. While at it skip also PCIe child buses.
