From dd83b06ae61cfa2dc4381ab49f365bd0995fc930 Mon Sep 17 00:00:00 2001 From: Andreas Färber Date: Sat, 28 Jan 2012 16:39:52 +0100 Subject: qom: Introduce CPU class MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reintroduce CPUState as QOM object: It's abstract and derived directly from TYPE_OBJECT for compatibility with the user emulators. The identifier CPUState avoids conflicts between CPU() and the struct. Introduce $(qom-twice-y) to build it separately for system and for user emulators. Prepare a virtual reset method, (re)introduce cpu_reset() as wrapper.
