[PATCH v4 0/5] Add horizontal mouse scroll support

[Dmitry Petrov]

This patchset adds implements passing horizontal scroll
events from the host system to guest systems via ps/2
mouse device.

This is useful during testing horizontal scroll behaviour
in guest operating systems as well as using it in case it
provides any benefits for a particular application.

The patch is based on the previous work by Brad Jorsch done
in 2010 but never merged, see
