Re: [Qemu-devel] ARM CPU affinities

 Actually, IMHO this code is quite universal. My initial idea was to introduce 
a global variable instead of ARM_CPUS_PER_CLUSTER definition. By setting this 
variable before creating CPU objects you could make whatever layout you want. 
But, yes, it always starts from 0. Perhaps you could add another global 
variable, like 'offset', in order to cover this.

 But, PM didn't want global variable. Okay, you can add a property and override 
this default during machine model creation. And this has nothing to do with 
KVM. KVM code is executed after default MPIDR is assigned and overrides IDs 
with whatever it gets from the kernel. All you can do with current kernels is 
to patch device tree with new IDs.
