Cc: alex.williamson@redhat.com Subject: [Qemu-devel] [PATCH v2 03/16] qdev: Add a get_dev_path() function to BusInfo 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 function is meant to provide a stable device path for buses which are able to implement it. If a bus has a globally unique addresses scheme, one address level may be sufficient to provide a path. Other buses may need to recursively traverse up the qdev tree.
