hw/core/machine-smp: Deprecate unsupported "parameter=1" SMP configurations
Currently, it was allowed for users to specify the unsupported
topology parameter as "1". For example, x86 PC machine doesn't
support drawer/book/cluster topology levels, but user could specify
"-smp drawers=1,books=1,clusters=1".
This is meaningless and confusing, so that the support for this kind of
configurations is marked deprecated since 9.0. And report warning
message for such case like:
qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
Unsupported clusters parameter mustn't be specified as 1
qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
Unsupported books parameter mustn't be specified as 1
qemu-system-x86_64: warning: Deprecated CPU topology (considered invalid):
Unsupported drawers parameter mustn't be specified as 1
Users have to ensure that all the topology members described with -smp
are supported by the target machine.
