The Chardev events are listed in the QEMUChrEvent enum. To be able to use this enum in the IOEventHandler typedef, we need to explicit all the events ignored by this frontend, to silent the following GCC warning: CC hw/char/virtio-console.o hw/char/virtio-console.c: In function ‘chr_event’: hw/char/virtio-console.c:154:5: error: enumeration value ‘CHR_EVENT_BREAK’ not handled in switch [-Werror=switch] 154 | switch (event) { | ^~~~~~ hw/char/virtio-console.c:154:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not handled in switch [-Werror=switch] hw/char/virtio-console.c:154:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ not handled in switch [-Werror=switch] cc1: all warnings being treated as errors Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> --- v2: Add all missing enums Cc: "Michael S.
