Cc: aliguori@us.ibm.com, armbru@redhat.com Subject: [Qemu-devel] [PATCH 5/5] PCI: do_pci_info(): PCI bridge devices support X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org This commit completes the do_pci_info() conversion to QObject by adding support to PCI bridge devices. This is done by recursively adding devices in the "pci_bridge" key. IMPORTANT: This code is being added separately because I could NOT test it properly. According to Michael Tsirkin, it depends on ultrasparc and it would take time to do the proper setup.
