    target-i386: Add "feature-words" property to X86CPU · 8e8aba50
    Eduardo Habkost authored
    
    
    This property will be useful for libvirt, as libvirt already has logic
    based on low-level feature bits (not feature names), so it will be
    really easy to convert the current libvirt logic to something using the
    "feature-words" property.
    
    The property will have two main use cases:
     - Checking host capabilities, by checking the features of the "host"
       CPU model
     - Checking which features are enabled on each CPU model
    
    Example output:
    
      $ ./QMP/qmp --path=/tmp/m \
        qom-get --path=/machine/icc-bridge/icc/child[0] \
                --property=feature-words
