From 6b1566cbe372660c77ca4aa7aa0071fa30f5f930 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Mon, 17 Mar 2014 13:40:23 +1100 Subject: qdev: Introduce FWPathProvider interface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit QEMU supports firmware names for all devices in the QEMU tree but some architectures expect some parts of firmware path names in different format. This introduces a firmware-pathname-change interface definition. If some machines needs to redefine the firmware path format, it has to add the TYPE_FW_PATH_PROVIDER interface to an object that is above the device on the QOM tree (typically /machine).
