[Qemu-devel] [PATCH 0/4] x86: Support "-cpu feature=force"

[Eduardo Habkost <ehabkost@redhat.com>]

This series implements "-cpu feature=force", to allow a feature
to be forcefully enabled even if the underlying accelerator
report it as unsupported. This feature should be used only for
testing and debugging.

We use a new QAPI alternate type to keep command-line
compatibility, and to keep compatibility with code that reads the
existing feature QOM properties and expects boolean values.

Eduardo Habkost (4):
  visitor: Add 'supported_qtypes' parameter to visit_start_alternate()
  string-input-visitor: Support alternate types
  tests: Add [+-]feature and feature=on|off test cases
  x86: Support feature=force on the command-line
