VM would not get those (it's global statistics), but the size could
balloon if you specify no target at all.
Adding a syntax for 'all' into the vcpus list would fix that?
I don't like having special syntax. The current QAPI just doesn't
filter what is not in the arguments.
"providers": [
{ "provider": "kvm",
"names": [ "l1d_flush", "exits" ] } } }
It's not clear to me whether the "target" should also be specific
to a given provider.
No, the target is a QEMU concept, such as a CPU or a device backend. It is
identified by either a QOM path or a unique id.
But doesn't 'kvm' as a provider only make sense for vcpus and VMs; if
you're imagining block devices and other things as targets it would seem
wrong to have that set of providers separate.
Yes, those would have different providers. But a single target can
support multiple providers.
