Wire up as default catch in parse_display(). Improves the error message for unknown display types. Also enables json as -display argument, i.e. -display "{ 'type': 'gtk' }" Signed-off-by: Gerd Hoffmann --- vl.c | 29 +++++++++++++++++++++++++++-- 1 file changed, 27 insertions(+), 2 deletions(-) diff --git a/vl.c b/vl.c index fce1fd12d8..784c3fb795 100644 --- a/vl.c +++ b/vl.c @@ -126,6 +126,7 @@ int main(int argc, char **argv) #include "sysemu/replay.h" #include "qapi/qapi-events-run-state.h" #include "qapi/qapi-visit-block-core.h" +#include "qapi/qapi-visit-ui.h" #include "qapi/qapi-commands-block-core.h" #include "qapi/qapi-commands-misc.h" #include "qapi/qapi-commands-run-state.h" @@ -2090,6 +2091,31 @@ static void select_vgahw(const char *p) } } +static void parse_display_qapi(const char *optarg) +{ + Error *err = NULL; + DisplayOptions *opts; + Visitor *v; + + v = qobject_input_visitor_new_str(optarg, "type", &err); + if (!v) { + error_report_err(err); + exit(1); + } + + visit_type_DisplayOptions(v, NULL, &opts, &error_fatal); + visit_free(v); + + /* + * We don't have any dynamically allocated stuff inside + * DisplayOptions, so we can simply copy the struct content and + * free opts without ending up with pointers pointing into + * nowhere. + */ + dpy = *opts; + qapi_free_DisplayOptions(opts); +} + static void parse_display(const char *p) { const char *opts; @@ -2201,8 +2227,7 @@ static void parse_display(const char *p) } else if (strstart(p, "none", &opts)) { dpy.type = DISPLAY_TYPE_NONE; } else { - error_report("unknown display type"); - exit(1); + parse_display_qapi(p); } }
