From d45f80ba82f281a35168011125cf6664cd217c22 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marc-Andr=C3=A9=20Lureau?= Date: Fri, 3 Nov 2017 16:28:24 +0100 Subject: [PATCH] test: add some chardev mux event tests MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Check the expected behaviour of qemu_chr_be_event() on a mux chardev. For some reason, sending the event on the base chardev broadcast to all frontends, while sending it on the mux chardev itself should trigger the event on the currently focused chardev frontend.
