An example of this in action can be seen here: https://fosstodon.org/@slp/109545849296546767 Since v1: - Split 0002 patch to implement ui, virtio-input-hid and virtio-input-pci changes in different patches (Marc-André). - Fix versioning in qapi/ui.json (Marc-André). - Print a warning if touch->sequence >= INPUT_EVENT_SLOTS_MAX (Marc-André). - Only send SYN_REPORT once, if needed (Marc-André). - Rebase and collect R-b.
