It makes sense to go with Drew's patches, so he doesn't need to re-base
his existing current implementation.

Yup. I was planning to send it as part of a small "hw/arm/virt: add
cpu-map" series I pretty much have ready, but didn't finish and send
yet because I got distracted working on the larger plan (among other
things). The motivation (larger plan) for cpu-map is full cpu-topology
configuration, but working on that has led to an smp parameter rework

patch now though to get it done sooner than later.

Thanks,

So is there a plan to provide a virt-2.7 for the next release?

Applied to target-arm.next, thanks.

[Qemu-devel] [PATCH V1 0/2] Versioning ARM virt machine types

[Wei Huang]

We start to see more features been added to ARM virtual machine models.
For the purpose of backward compatibility (e.g. migration), it is time
to consider versioning machine types for ARM VMs. As a beginning step, this
patchset defines an abstract machine type for ARM VMs. The current
"virt" machine is re-written based on this new abstract type accordingly.
These patches have been verified by booting existing VMs.

RFC->V1:
 * Rename the machine type to "virt-2.6", matching the imminent QEMU version
 * Remove mc->is_default (Peter's comment)

Thanks,
-Wei

  arm: virt: Add an abstract ARM virt machine type
  arm: virt: Move machine class init code to the abstract machine type
