From eb2e259d95a67ef0cd8a61c0bd4974559e9bfa5d Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Tue, 9 Mar 2010 14:26:40 -0600 Subject: [PATCH] Add kbd_mouse_has_absolute() kbd_mouse_is_absolute tells us whether the current mouse handler is an absolute device. kbd_mouse_has_absolute tells us whether we have any device that is capable of absolute input. This lets us tell a user that they have configured an absolute device but that the guest is not currently using it.
