Currently the common structure base provides the name of the accelerator, while the specific part is empty, but each accelerator can expand it. - 'query-accels' QMP command returns a list of @AcceleratorInfo For example on a KVM-only build we get: { "execute": "query-accels" } { "return": [ { "name": "qtest" }, { "name": "kvm" } ] } Reviewed-by: Eric Blake <ebl...@redhat.com> Reviewed-by: Alex Bennée <alex.ben...@linaro.org> Tested-by: Alex Bennée <alex.ben...@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <phi...@redhat.com> --- v8: - Include code snippet from Markus adding to machine-target.json to be able to use enum values or union branches conditional. - Use accel_find() on enum to be sure the accelerator is enabled at runtime (chat with jsnow / eblake).
