This series adds a virtio-multitouch device to the family of devices emulated by virtio-input implementing the Multi-touch protocol as descripted here:
https://www.kernel.org/doc/html/latest/input/multi-touch-protocol.html?highlight=multi+touch It also extends the GTK UI backend to be able to receive multi-touch events and transpose them to a guest, so the latter can recognize them as gestures when appropriate. An example of this in action can be seen here: https://fosstodon.org/@slp/109545849296546767 Since v2: - Fix InputMultitouchEvent doc in qapi/ui.json (Marc-André). - Use warn_report() instead of fprintf() in gtk.c (Marc-André). - Rebase and collect R-b. 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.
