Subject: [Qemu-devel] [PATCH] i386/vmmouse: Properly reset state
Date: Sun, 21 Jul 2019 10:58:56 +0200 [thread overview]
Message-ID: <f056c7e5-fa74-469c-87f8-0f0925301b2d@web.de> (raw)
From: Jan Kiszka <jan.kiszka@siemens.com>
nb_queue was not zeroed so that we no longer delivered events if a
previous guest left the device in an overflow state.
The state of absolute does not matter as the next vmmouse_update_handler
call will align it again.
