Remove the dependency of vkbd on vfb: use qemu_console_lookup_by_index to find the principal console (to get the size of the screen) instead of relying on a vfb backend to be available (which adds a dependency between the two). Signed-off-by: Stefano Stabellini Reviewed-by: Paul Durrant --- Note that this patch conflicts with Owen's series (http://marc.info/?l=qemu-devel&m=149908803419893&w=2). However it should be very easy to rebase one on top of the other. Changes in v3: - use qemu_console_lookup_by_index to find the console from xenfb_mouse_event - remove con from struct common and add it to struct XenFB - remove in->c.con check from input_initialise Changes in v2: - remove xen_init_display from xen_backend.h - handle cases where vkbd is missing diff --git a/hw/display/xenfb.c b/hw/display/xenfb.c index e76c0d8..df8b78f 100644 --- a/hw/display/xenfb.c +++ b/hw/display/xenfb.c @@ -46,7 +46,6 @@ struct common { struct XenDevice xendev;
