# of a certain configuration (e.g. the "host" model for KVM). If that CPU
# model is identical or a subset, it will run in that configuration.
#
# The result returned by this command may be affected by:

# * QEMU version: CPU models may look different depending on the QEMU version.
# (Except for CPU models reported as "static" in query-cpu-definitions.)
# * machine-type: CPU model may look different depending on the machine-type.

# * machine options (including accelerator): in some architectures, CPU models
# may look different depending on machine and accelerator options. (Except for

# This interface can be used by tooling to create a compatible CPU model out

# @typename: Type name that can be used as argument to @device-list-properties,

# (since 2.9)
#
# @unavailable-features is a list of QOM property names that
# represent CPU model attributes that prevent the CPU from running.

# way to make the CPU model run in the current host. Implementations
# that choose not to provide specific information return the
# property name "type".
# If the property is read-write, it means that it MAY be possible
# to run the CPU model in the current host if that property is
# changed. Management software can use it as hints to suggest or
# choose an alternative for the user, or just to generate meaningful
# error messages explaining why the CPU model can't be used.
# If @unavailable-features is an empty list, the CPU model is
# runnable using the current host and machine-type.

# information for the CPU is not available.
