Anthony Liguori has contributed the QEMU Object Model (QOM) as new infrastructure for device modeling and inspection at the beginning of this year. Highlight some of the changes for device authors this requires and provide an outlook of what new possibilities this offers over former qdev. Focus of this talk will be my ongoing CPU remodeling - vision, achievements for v1.1 and v1.2, next goals.
I assume that Anthony will say some words about QOM in his key note. This presentation will not cover the why/how but rather the how-to and where-to for device authors in the status quo as well as some DOs and DON'Ts concerning CPU*State for all contributors. Depending on upstream progress this talk might also cover a brief overview of differences between softmmu and linux-user wrt CPU. I don't plan to go into x86 CPU hotplug details, that could well be covered by Igor/Eduardo in a separate talk.
