[Qemu-devel] [PATCH 0/2] machine opts framework

[Glauber Costa]

This patch adds initial support for the -machine option, that allows
command line specification of machine attributes (always relying on safe
defaults). Besides its value per-se, it is the saner way we found to
allow for enabling/disabling of kvm's in-kernel irqchip.
    
A machine with in-kernel-irqchip could be specified as:
    -machine irqchip=apic-kvm
And one without it:
    -machine irqchip=apic
    
To demonstrate how it'd work, this patch introduces a choice between
"pic" and "apic", pic being the old-style isa thing. It does introduce
a behavioral change, however: In old code, pic would always be a fallback.
Now, it will have to be explicitly selected. I believe it is better behaviour,
but this is not the most important part of it, so I can easily go back
if people want it out.
    
Let the flames begin!
