Subject: [PATCH] hw/i386/vmmouse: Require 'i8042' property to be set
|
|
MIME-Version: 1.0

cherry picked from commit 5a3a2eb3b1096a52580c1b8c3eb0739714e7d941
|
|
|
|
If the 'i8042' property is not set, mouse events handled by
|
|
vmmouse_mouse_event() end calling i8042_isa_mouse_fake_event()
|
|
with a NULL argument, resulting in ps2_mouse_fake_event() being
|
|
called with invalid PS2MouseState pointer. Fix by requiring
|
|
the 'i8042' property to be always set:
|
|
|
|
$ qemu-system-x86_64 -device vmmouse
|
|
qemu-system-x86_64: -device vmmouse: 'i8042' link is not set
|
|
|
|
